Item 1.

Business.

Overview

Middlesex Water Company (Middlesex) was incorporated as a water utility company in 1897 and owns and operates regulated water utility and wastewater systems in New Jersey, Delaware and Pennsylvania. Middlesex also operates water and wastewater systems under contract on behalf of municipal and private clients in New Jersey and Delaware.

The terms “the Company,” “we,” “our,” and “us” refer to Middlesex Water Company and its subsidiaries, including Tidewater Utilities, Inc. (Tidewater) and Tidewater’s wholly-owned subsidiaries, Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh). The Company’s other subsidiaries are Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy) Inc., (USA-PA), Tidewater Environmental Services, Inc. (TESI) and Twin Lakes Utilities, Inc. (Twin Lakes).

The Company’s principal executive offices are located at 1500 Ronson Road, Iselin, New Jersey 08830. Our telephone number is (732) 634-1500. Our website address is http://www.middlesexwater.com. We make available, free of charge through our website, reports and amendments filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, after such material is electronically filed with or furnished to the United States Securities and Exchange Commission (the SEC).

Middlesex System

The Middlesex System in New Jersey provides water services to approximately 61,000 retail customers, primarily in eastern Middlesex County, New Jersey and provides water under wholesale contracts to the City of Rahway, Townships of Edison and Marlboro, the Borough of Highland Park and the Old Bridge Municipal Utilities Authority. The Middlesex System treats, stores and distributes water for residential, commercial, industrial and fire protection purposes. The Middlesex System also provides water treatment and pumping services to the Township of East Brunswick under contract. The amount of water supply allocated to the Township of East Brunswick is granted directly to the Township by the New Jersey Water Supply Authority. The Middlesex System produced approximately 60% of our 2016 consolidated operating revenues.

The Middlesex System’s retail customers are located in an area of approximately 55 square miles in Woodbridge Township, the City of South Amboy, the Boroughs of Metuchen and Carteret, portions of the Township of Edison and the Borough of South Plainfield in Middlesex County and, to a minor extent, a portion of the Township of Clark in Union County. Retail customers include a mix of residential customers, large industrial concerns and commercial and light industrial facilities. These customers are located in generally well-developed areas of central New Jersey.

The contract customers of the Middlesex System comprise an area of approximately 110 square miles with a population of approximately 219,000. Contract sales to the Townships of Edison and Marlboro, the City of Rahway and the Old Bridge Municipal Utilities Authority are supplemental to the water systems owned and operated by these customers. Middlesex is the sole source of water for the Borough of Highland Park and the Township of East Brunswick.

Middlesex provides water service to approximately 300 customers in Cumberland County, New Jersey. This system is referred to as Bayview, and is not physically interconnected with the Middlesex System. Bayview produced less than 1% of our 2016 consolidated operating revenues.

Index

Tidewater System

Tidewater, together with its wholly-owned subsidiary, Southern Shores, provides water services to approximately 43,000 retail customers for residential, commercial and fire protection purposes in nearly 400 separate communities in New Castle, Kent and Sussex Counties, Delaware. White Marsh is a wholly-owned subsidiary of Tidewater that is unregulated as to rates and operates or maintains more than 50 water and/or wastewater systems under contracts that serve approximately 4,000 residential customers. White Marsh owns two commercial properties that are leased to Tidewater as its administrative office campus and its field operations center. The Tidewater System produced approximately 26% of our 2016 consolidated operating revenues.

Utility Service Affiliates-Perth Amboy

USA-PA operates the City of Perth Amboy, New Jersey’s (Perth Amboy) water treatment and distribution system and its wastewater collection system under a 20-year agreement, which expires in 2018. USA-PA serves approximately 11,700 homes and businesses, most of which are served by both the water and wastewater systems. Under the agreement, USA-PA receives fixed fees, and may receive variable fees, based on customer revenue growth. Fixed fee revenues increase over the term of the 20-year contract based upon a schedule of rates. USA-PA produced approximately 8% of our 2016 consolidated operating revenues.

In connection with the agreement with Perth Amboy, USA-PA entered into a subcontract with a wastewater operating company for the operation and maintenance of the Perth Amboy wastewater collection system. The subcontract provides for the sharing of certain fixed and variable fees and operating expenses and its term is concurrent with USA-PA’s contract with Perth Amboy.

Pinelands System

Pinelands Water provides water services to approximately 2,500 residential customers in Burlington County, New Jersey. Pinelands Water produced less than 1% of our 2016 consolidated operating revenues. Pinelands Water is not physically interconnected with the Middlesex System.

Pinelands Wastewater provides wastewater collection and treatment services to approximately 2,500 residential customers. Under contract, it also services one municipal wastewater system in Burlington County, New Jersey with approximately 200 residential customers. Pinelands Wastewater produced approximately 1% of our 2016 consolidated operating revenues.

Utility Service Affiliates, Inc.

USA operates the Borough of Avalon, New Jersey’s (Avalon) water utility, sewer utility and storm water system under a ten-year operations and maintenance contract expiring in 2022. USA serves approximately 6,200 Avalon homes and businesses, most of which are served by both the water and wastewater collection systems. In addition to performing day-to-day operations, USA is responsible for billing, collections, customer service, emergency responses and management of capital projects funded by Avalon.

USA also provides unregulated water and wastewater services under contract with several other smaller New Jersey municipalities.

Under a marketing agreement with HomeServe USA (HomeServe), USA offers residential customers in New Jersey and Delaware various water and wastewater related home maintenance programs. HomeServe is a leading national provider of such home maintenance service programs. USA receives a service fee for the billing, cash collection and other administrative matters associated with HomeServe’s service contracts. The agreement expires in 2021.

USA produced approximately 2% of our 2016 consolidated operating revenues.

Index

TESI System

TESI provides wastewater collection and treatment services to approximately 3,400 residential retail customers in Sussex County, Delaware. TESI produced approximately 2% of our 2016 consolidated operating revenues.

Twin Lakes System

Twin Lakes provides water services to approximately 120 residential customers in Shohola, Pennsylvania. Twin Lakes produced less than 1% of our 2016 consolidated operating revenues.

Water Supplies and Contracts

Our New Jersey, Delaware and Pennsylvania water supply systems are physically separate and are not interconnected. In New Jersey, the Pinelands System and Bayview System are not interconnected with the Middlesex System or each other. We believe we have adequate sources of water supply to meet the current service requirements of our present customers in New Jersey, Delaware and Pennsylvania.

Middlesex System

Our Middlesex System, which produced approximately 15.1 billion gallons in 2016, obtains water from surface sources and wells (groundwater sources). In 2016, surface sources of water provided approximately 74% of the Middlesex System’s water supply, groundwater sources provided approximately 19% from 31 wells and the balance was purchased from a non-affiliated regulated water utility. The Middlesex System’s distribution storage facilities are used to supply water to customers at times of peak demand, outages and emergencies.

The principal source of surface water for the Middlesex System is the Delaware & Raritan Canal, which is owned by the State of New Jersey and operated as a water resource by the New Jersey Water Supply Authority (NJWSA). Middlesex is under contract with the NJWSA, which expires November 30, 2023, and provides for

Index

average purchases of 27.0 million gallons per day (mgd) of untreated water from the Delaware & Raritan Canal, augmented by the Round Valley/Spruce Run Reservoir System. The untreated surface water is pumped to, and treated at, the Middlesex Carl J. Olsen (CJO) Water Treatment Plant. Middlesex also has an agreement with a non-affiliated regulated water utility for the purchase of treated water. This agreement, which expires February 27, 2021, provides for minimum purchase of 3.0 mgd of treated water with provisions for additional purchases.

Tidewater System

Our Tidewater System produced approximately 2.1 billion gallons in 2016 from 162 wells. Tidewater expects to submit applications to Delaware regulatory authorities for the approval of additional wells as growth, customer demand and water quality warrant. Tidewater augments its water production with annual minimum purchases of 15.0 million gallons of treated water under contract from the City of Dover, Delaware. Tidewater does not have a central water treatment facility for the nearly 400 separate communities it serves. As the number has grown, many of Tidewater’s individual systems have been interconnected, forming several regional systems that are served by multiple water treatment facilities.

Pinelands Water System

Water supply to our Pinelands Water System is derived from four wells which produced approximately 152.0 million gallons in 2016. The aggregate pumping capacity of the four wells is 2.2 mgd.

Pinelands Wastewater System

The Pinelands Wastewater System discharges into the South Branch of the Rancocas Creek through a tertiary treatment plant that provides clarification, sedimentation, filtration and disinfection. The total capacity of the plant is 0.5 mgd, and the system treated approximately 95.8 million gallons in 2016.

Bayview System

Water supply to Bayview customers is derived from two wells, which produced approximately 7.3 million gallons in 2016.

TESI System

The TESI System is comprised of seven wastewater treatment systems in Sussex County, Delaware, which are not interconnected. The treatment plants provide clarification, sedimentation, and disinfection. The combined total treatment capacity of the plants is 0.7 mgd. The TESI System treated approximately 107.7 million gallons in 2016.

Twin Lakes System

Water supply to Twin Lakes’ customers is derived from one well, which produced approximately 15.4 million gallons in 2016.

Employees

As of December 31, 2016, we had a total of 309 employees. None of our employees are subject to a collective bargaining agreement. We believe our employee relations are positive. Wages and benefits are reviewed annually and are considered competitive within both the industry and the regions where we operate.

Competition

Our business in our franchised service areas is substantially free from direct competition with other public utilities, municipalities and other entities. However, our ability to provide contract water supply and wastewater services and operations and maintenance services that are not under the jurisdiction of a state public utility commission is subject to competition from other public utilities, municipalities and other entities. Although

Index

Tidewater and TESI have been granted exclusive franchises for each of their existing community water and wastewater systems, their ability to expand service areas can be affected by the Delaware Public Service Commission awarding franchises to other regulated water and wastewater utilities with whom we compete for such franchises and for projects.

Regulation

Our rates charged to customers for water and wastewater services, the quality of the services we provide and certain other matters are regulated by the following state utility commissions (collectively, the Utility Commissions):

New Jersey-New Jersey Board of Public Utilities (NJBPU)

Delaware-Delaware Public Service Commission (DEPSC)

Pennsylvania-Pennsylvania Public Utilities Commission (PAPUC)

Our USA, USA-PA and White Marsh subsidiaries are not regulated public utilities. However, they are subject to environmental regulation with respect to water quality and wastewater effluent quality to the extent such services are provided.

We are subject to environmental and water quality regulation by the following regulatory agencies (collectively, the Government Environmental Regulatory Agencies):

United States Environmental Protection Agency (EPA)

New Jersey Department of Environmental Protection (NJDEP) with respect to operations in New Jersey

Delaware Department of Natural Resources and Environmental Control, the Delaware Department of Health and Social Services-Division of Public Health (DEDPH), and the Delaware River Basin Commission (DRBC) with respect to operations in Delaware

Pennsylvania Department of Environmental Protection (PADEP) with respect to operations in Pennsylvania

In addition, our issuances of equity securities are subject to the prior approval of the NJBPU and require registration with the SEC. Our issuances of long-term debt securities are subject to the prior approval of the appropriate Utility Commissions.

Regulation of Rates and Services

For regulated rate setting purposes, we account separately for operations in New Jersey, Delaware and Pennsylvania to facilitate independent rate setting by the applicable Utility Commissions.

In determining our regulated utility rates, the respective Utility Commissions consider the revenue, expenses, rate base of property used and useful in providing service to the public and a fair rate of return on investments within their separate jurisdictions. Rate determinations by the respective Utility Commissions do not guarantee achievement to us of specific rates of return for our New Jersey, Delaware and Pennsylvania regulated utility operations. Thus, we may not achieve the stated rates of return authorized by the Utility Commissions. In addition, there can be no assurance that any future rate increases will be granted or, if granted, that they will be in the amounts requested.

Middlesex Rate Matters

In August 2015, Middlesex’s Petition to the NJBPU seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $5.0 million. The new base water rates were needed to recover increased costs and lost customer revenues, as well as a return on invested capital in rate base of $219.0 million, based on a return on equity of 9.75%. The rate increase became effective on August 29, 2015.

Index

In June 2014, Middlesex’s Petition to the NJBPU seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $4.2 million. The new base water rates were designed to recover increased costs and lost customer revenues, as well as a return on invested capital in rate base of $208.6 million, based on a return on equity of 9.75%. The rate increase became effective on July 20, 2014.

On November 1, 2016, Middlesex implemented a NJBPU-approved purchased water adjustment clause sufficient to recover additional costs of less than $0.1 million for the purchase of treated water from a non-affiliated regulated water utility.

Tidewater Rate Matters

In August 2014, Tidewater’s Application to the DEPSC seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $0.8 million. The new base water rates were designed to recover increased costs and a return on invested capital in rate base of $208.6 million, based on a return on equity of 9.75%. The rate increase became effective on August 19, 2014.

Effective January 1, 2017, Tidewater increased its DEPSC-approved Distribution System Improvement Charge (DSIC) rate, which is expected to generate revenues of approximately $0.3 million annually.

In April 2014, the DEPSC approved Tidewater’s 50-year agreement with the United States Department of Defense for the privatization of the water system of Dover Air Force Base (DAFB) in Dover, Delaware. On October 1, 2014, Tidewater assumed ownership of the DAFB water utility assets and began providing regulated water service to DAFB under Tidewater’s DEPSC approved tariff rates.

TESI Rate Matters

In October 2014, TESI implemented a DEPSC-approved 33.5% base wastewater rate increase for residential customers in the Plantations development in Delaware (approximately $0.1 million annually).

Pinelands Rate Matters

In April 2016, the NJBPU approved $0.2 million and $0.1 million of increases, respectively, in Pinelands Water and Pinelands Wastewater’s annual base rates, effective May 7, 2016. In October 2015, the companies had filed petitions with the NJBPU seeking permission to increase base rates by approximately $0.5 million per year. The rate filings were necessitated by capital infrastructure investments the companies have made, or have committed to make, increased operations and maintenance costs and lower non-fixed fee revenues. The Pinelands Water base water rate increase will be phased-in over two years.

Southern Shores Rate Matters

Under the terms of a multi-year DEPSC-approved agreement expiring in 2020, customer rates will increase on January 1^st of each year to generate additional annual revenue of $0.1 million with each increase.

Twin Lakes Rate Matters

In June 2016, the PAPUC approved a $0.1 million increase in Twin Lakes’ base water rates, effective June 15, 2016. In November 2015, Twin Lakes had filed a petition seeking permission to increase its base water rates by approximately $0.2 million per year. This request was necessitated by capital infrastructure investments Twin Lakes has made, or committed to make, and increased operations and maintenance costs. The rate increase will be phased in over two years.

Future Rate Filings

Management monitors the need for rate relief for our regulated subsidiaries on an ongoing basis. When capital improvements (both made and planned) and/or increases in operation and maintenance costs require rate relief, base rate increase requests are expeditiously filed with those subsidiaries’ Utility Commissions.

Index

Water and Wastewater Quality and Environmental Regulations

Regulations relating to water quality require us to perform tests to ensure our water meets state and federal quality requirements. In addition, government environmental regulatory agencies continuously review current regulations governing the limits of certain organic compounds found in the water as byproducts of the treatment process. We participate in industry-related research to identify the various types of technology that might reduce the level of organic, inorganic and synthetic compounds found in water. The cost to water utilities to comply with the proposed water quality standards depends in part on the limits set in the regulations and on the method selected to treat the water to the required standards. We regularly test our water to determine compliance with existing required government environmental regulatory agencies’ water quality standards.

Treatment of groundwater in our Middlesex System is by chlorination for primary disinfection purposes. In addition, at certain locations, air stripping is used for removal of volatile organic compounds.

Surface water treatment in our Middlesex System is by conventional treatment; coagulation, sedimentation and filtration. The treatment process includes pH adjustment, chlorination for disinfection, and corrosion control for the distribution system.

Treatment of groundwater in our Tidewater System is by chlorination for disinfection purposes and, in some cases, pH correction and filtration for nitrate and iron removal and granular activated carbon filtration for organics removal. Chloramination is used for final disinfection at Southern Shores.

Treatment of groundwater in the Pinelands, Bayview and Twin Lakes Systems (primary disinfection only) is performed at individual well sites.

The NJDEP, DEDPH and PADEP monitor our activities and review the results of water quality tests that are performed for adherence to applicable regulations. Other applicable regulations include the Federal Lead and Copper Rule, the Federal Surface Water Treatment Rule and the Federal Total Coliform Rule and regulations for maximum contaminant levels established for various volatile organic compounds.

Seasonality

Customer demand for our water during the warmer months is generally greater than other times of the year due primarily to additional consumption of water in connection with irrigation systems, swimming pools, cooling systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand may vary with temperature and rainfall timing and overall levels. In the event that temperatures during the typically warmer months are cooler than normal, or if there is more rainfall than normal, the customer demand for our water may decrease and therefore, adversely affect our revenues.

ITEM 1A.

RISK FACTORS.

Our revenue and earnings depend on the rates we charge our customers. We cannot raise utility rates in our regulated businesses without filing a petition with the appropriate Utility Commissions. If these agencies modify, delay, or deny our petition, our revenues will not increase and our earnings will decline unless we are able to reduce costs.

The NJBPU regulates our public utility companies in New Jersey with respect to rates and charges for service, classification of accounts, awards of new service territory, acquisitions, financings and other matters. That means, for example, that we cannot raise the utility rates we charge to our customers without first filing a petition with the NJBPU and going through a lengthy administrative process. In much the same way, the DEPSC and the PAPUC regulate our public utility companies in Delaware and Pennsylvania, respectively. We cannot give assurance of when we will request approval for any such matter, nor can we predict whether these Utility Commissions will approve, deny or reduce the amount of such requests.

Certain costs of doing business are not completely within our control. The failure to obtain any rate increase would prevent us from increasing our revenues and, unless we are able to reduce costs, would result in reduced earnings.

General economic conditions may materially and adversely affect our financial condition and results of operations.

Adverse economic conditions could negatively impact our customers’ water usage demands, particularly the level of water usage demand by our commercial and industrial customers in our Middlesex System. If water demand by our commercial and industrial customers in our Middlesex System were negatively impacted, our financial condition and results of operations could continue to be negatively impacted.

We are subject to environmental laws and regulations, including water quality and wastewater effluent quality regulations, as well as other state and local regulations. Compliance with those laws and regulations requires us to incur costs and we are subject to fines or other sanctions for non-compliance.

Government environmental regulatory agencies regulate our operations in New Jersey, Delaware and Pennsylvania with respect to water supply, treatment and distribution systems and the quality of water. Government environmental regulatory agencies’ regulations relating to water quality require us to perform expanded types of testing to ensure that our water meets state and federal water quality requirements. We are subject to EPA regulations under the Federal Safe Drinking Water Act, which include the Lead and Copper Rule, the maximum contaminant levels established for various volatile organic compounds, the Federal Surface Water Treatment Rule and the Total Coliform Rule. There are also similar NJDEP regulations for our New Jersey water systems. The NJDEP, DEDPH and PADEP monitor our activities and review the results of water quality tests that we perform for adherence to applicable regulations. In addition, Government Environmental Regulatory Agencies are continually reviewing regulations governing the limits of certain organic compounds found in the water as byproducts of treatment.

Index

We are also subject to regulations related to fire protection services in New Jersey and Delaware. In New Jersey there is no state-wide fire protection regulatory agency. However, New Jersey regulations exist as to the size of piping required regarding the provision of fire protection services. In Delaware, fire protection is regulated statewide by the Office of State Fire Marshal.

The cost of compliance with the water and wastewater effluent quality standards depends in part on the limits set in the regulations and on the method selected to implement them. If new or more restrictive standards are imposed, the cost of compliance could be very high and have an adverse impact on our revenues and results of operations if we cannot recover those costs through our rates that we charge our customers. The cost of compliance with fire protection requirements could also be high and make us less profitable if we cannot recover those costs through our rates charged to our customers.

In addition, if we fail to comply with environmental or other laws and regulations to which our business is subject, we could be fined or subject to other sanctions, which could adversely impact our business or results of operations.

We depend upon our ability to raise money in the capital markets to finance some of the costs of complying with laws and regulations, including environmental laws and regulations or to pay for some of the costs of improvements to or the expansion of our utility system assets. Our regulated utility companies cannot issue debt or equity securities without regulatory approval.

We require financing to fund the ongoing capital program for the improvement in our utility system assets and for planned expansion of those systems. We expect to spend approximately $223 million for capital projects through 2019. We must obtain approval from our economic regulators to sell debt or equity securities to raise money for these projects. If sufficient capital is not available, or the cost of capital is too high, or if the regulatory authorities deny a petition of ours to sell debt or equity securities, we may not be able to meet the costs of complying with environmental laws and regulations or the costs of improving and expanding our utility system assets to the level we believe operationally prudent. This may result in the imposition of fines from environmental regulators or restrictions on our operations which could curtail our ability to upgrade or replace utility system assets.

We rely on our information technology systems to help manage our operations.

Our information technology systems require periodic modifications, upgrades and or replacement which subject us to costs and risks including potential disruption of our internal control structure, substantial capital expenditures, additional administration and operating expenses, retention of sufficiently skilled personnel to implement and operate existing or new systems, and other risks and costs of delays or difficulties in transitioning to new systems or of integrating new systems into our current systems. In addition, challenges implementing new technology systems may cause disruptions in our business operations and have an adverse effect on our business operations, if not anticipated and appropriately mitigated.

We rely on our computer, information and communications technology systems in connection with the operation of our business, especially with respect to customer service and billing, accounting and, in some cases, the monitoring and operation of our operating facilities. Our computer and communications systems and operations could be damaged or interrupted by natural disasters, power loss and internet, telecommunications or data network failures or acts of war or terrorism or similar events or disruptions. Any of these or other events could cause service interruption, delays and loss of critical data or, impede aspects of operations and therefore, adversely affect our financial results.

Cyber-attacks on entities around the world have caused operational failures and/or compromised corporate and personal data. Such attacks could result in the loss, or compromise, of customer, financial or operational data, disruption of billing, collections or normal field service activities, disruption of electronic monitoring and control of operational systems and delays in financial reporting and other management functions. Possible impacts associated with a cyber-incident may include remediation costs related to lost, stolen, or compromised data, repairs to data processing systems, increased cyber security protection costs, adverse effects on our compliance

with regulatory and environmental laws and regulation, including standards for drinking water, litigation and reputational damage.

Weather conditions and overuse of underground aquifers may interfere with our sources of water, demand for water services and our ability to supply water to customers.

Our ability to meet current and future water demands of our customers depends on the availability of an adequate supply of water. Unexpected conditions may interfere with our water supply sources. Drought and overuse of underground aquifers may limit the availability of ground and/or surface water. Freezing weather may also contribute to water transmission interruptions caused by water main breakage. Any interruption in our water supply could cause a reduction in our revenue and profitability. These factors may adversely affect our ability to supply water in sufficient quantities to our customers. Governmental drought restrictions may result in decreased customer demand for water services and can adversely affect our revenue and earnings.

Our business is subject to seasonal fluctuations, which could affect demand for our water service and our revenues.

Demand for our water during the warmer months is generally greater than during cooler months due primarily to additional consumption of water in connection with irrigation systems, swimming pools, cooling systems and other outdoor water use. Throughout the year, and particularly during typically warmer months, demand may vary with temperature and rainfall levels. In the event that temperatures during the typically warmer months are cooler than normal, or if there is more rainfall than normal, the demand for our water may decrease and adversely affect our revenues.

Our water sources or water service provided to customers may become contaminated by naturally-occurring or man-made compounds and events. This may cause disruption in services and impose operational and regulatory enforcement costs upon us to restore the water to required levels of quality as well as may damage our reputation and cause private litigation claims against us.

Our sources of water or water in our distribution systems may become contaminated by naturally-occurring or man-made compounds or other events. In the event that any portion of our water supply sources or water distribution systems is contaminated, we may need to interrupt service to our customers until we are able to remediate the contamination or substitute the flow of water from an uncontaminated water source through existing interconnections with other water purveyors or through our transmission and distribution systems, where possible. We may also incur significant costs in treating any contaminated water, or remediating the effects on our treatment and distribution systems, through the use of our current treatment facilities, or development of new treatment methods. Our inability to substitute water supply from an uncontaminated water source, or to adequately treat the contaminated water supply in a cost-effective manner, may reduce our revenues and make us less profitable.

We may be unable to recover costs associated with treating or decontaminating water supplies through rates, or recovery of these costs may not occur in a timely manner. In addition, we could be subject to claims for damages arising from government enforcement actions or other lawsuits arising out of interruption of service or human exposure to hazardous substances in our drinking water and water supplies. Such costs could adversely affect our financial results.

Contamination of the water supply or the water service provided to our customers could result in substantial injury or damage to our customers, employees or others and we could be exposed to substantial claims and litigation, which are inherently subject to uncertainties and are potentially subject unfavorable rulings. Negative impacts to our profitability and our reputation may occur even if we are not responsible for the contamination or the consequences arising out of human exposure to contamination or hazardous substances in the water or water supplies. Pending or future claims against us could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Index

We face competition from other water and wastewater utilities and service providers which might hinder our growth and reduce our profitability.

We face risks of competition from other utilities or other entities authorized by federal, state or local agencies to provide utility services. Once a state utility regulator grants a franchise to a utility to serve a specific territory, that utility effectively has an exclusive right to service that territory. Although a new franchise offers some protection against competitors, the pursuit of franchises is often competitive, particularly in Delaware, where new franchises may be awarded to utilities based upon competitive negotiation. Competing entities have challenged, and may challenge in the future, our applications for new franchises. Also, third parties entering into long-term agreements to operate municipal utility systems may adversely affect our long-term agreements to supply water or wastewater services on a contract basis to municipalities, which could adversely affect our financial results.

We have long-term contractual obligations for water, wastewater and storm water system operation and maintenance under which we may incur costs in excess of payments received.

USA-PA operates and maintains the water and wastewater systems of Perth Amboy under a 20-year contract expiring in 2018. USA operates and maintains the water, wastewater and storm water systems of Avalon under a 10-year contract expiring in 2022. These contracts do not protect us against incurring costs in excess of revenues we earn pursuant to the contracts. There can be no absolute assurance that we will not experience losses resulting from these contracts. Losses under these contracts, or our failure or inability to perform, may have a material adverse effect on our financial condition and results of operations.

We serve as guarantor of performance of an unaffiliated company that operates a leachate pretreatment facility at the Monmouth County Reclamation Center in Tinton Falls, New Jersey.

Middlesex entered into agreements, expiring in 2028, with Applied Water Management, Inc. (AWM), Natural Systems Utilities, LLC, (NSU) the parent company of AWM, and the County of Monmouth, New Jersey (County) for the operation of a leachate pretreatment facility at the Monmouth County Reclamation Center in Tinton Falls, New Jersey. Under the terms of the agreement, AWM operates the County-owned landfill leachate pretreatment facility. Middlesex is the guarantor of AWM's performance under the agreement (the Guaranty), for which Middlesex earns a fee, in addition to providing operational support if necessary. If asked to perform under the Guaranty, Middlesex could be required to fulfill the remaining operational commitments of AWM. There can be no absolute assurance that we will not experience losses if asked to perform under the Guaranty. Losses from performance under this Guaranty, or our failure or inability to perform, may have a material adverse effect on our financial condition and results of operations. NSU and AWM have agreed to indemnify Middlesex for any costs Middlesex may incur in connection with its Guaranty to the County.

Capital market conditions and key assumptions may adversely impact the value of our postretirement benefit plan assets and liabilities.

Market factors can adversely affect the rate of return on assets held in trusts to satisfy our future postretirement benefit obligations as well negatively affect interest rates, which impacts the discount rates used in the determination of our postretirement benefit actuarial valuations. In addition, changes in demographics, such as increases in life expectancy assumptions, can increase future postretirement benefit obligations. Any negative impact to these factors, either individually or a combination thereof, may have a material adverse effect on our financial condition and results of operations.

An important element of our growth strategy is the acquisition of water and wastewater assets, operations, contracts or companies. Any pending or future acquisitions we decide to undertake may involve risks.

The acquisition and/or operation of water and wastewater systems is an element of our growth strategy. This strategy depends on identifying suitable opportunities and reaching mutually agreeable terms with acquisition candidates or contract partners. Further, acquisitions may result in dilution of our equity securities, incurrence of

Index

debt and contingent liabilities, fluctuations in quarterly results and other related expenses. In addition, the assets, operations, contracts or companies we acquire may not achieve the sales and profitability expected.

The current concentration of our business in central New Jersey and Delaware makes us susceptible to adverse development in local regulatory, economic, demographic, competitive and weather conditions.

Our New Jersey water and wastewater businesses provide services to customers who are located primarily in eastern Middlesex County, New Jersey. Water service is provided under wholesale contracts to the Townships of Edison, East Brunswick and Marlboro, the Borough of Highland Park, the Old Bridge Municipal Utilities Authority, and the City of Rahway in Union County, New Jersey. We also provide water and wastewater services to customers in the State of Delaware. Our revenues and operating results are therefore subject to local regulatory, economic, demographic, competitive and weather conditions in a relatively concentrated geographic area. A change in any of these conditions could make it more costly for us to conduct our business.

The necessity for ongoing security has and may continue to result in increased operating costs.

Because of physical and operational threats to the health and security of the United States of America, we employ procedures to review and modify, as necessary, physical and other security measures at our facilities. We provide ongoing training and communications to our employees about threats to our water supply, our assets and related systems and our employees’ personal safety. We have incurred, and will continue to incur, costs for security measures to protect against such risks.

Our ability to achieve organic growth in our market area is dependent on the residential building market. Housing starts are one element that impacts our rate of growth and therefore, may not meet our expectations.

We expect our revenues to increase from customer growth for our regulated water and wastewater operations as a result of anticipated construction and sale of new housing units. If housing starts decline, or do not increase as we have projected, as a result of economic conditions or otherwise, the timing and extent of our organic revenue growth may not meet our expectations, our deferred project costs may not produce revenue-generating projects in the timeframes anticipated and our financial results could be negatively impacted.

There can be no assurance that we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.

We have paid dividends on our common stock each year since 1912 and have increased the amount of dividends paid each year since 1973. Our earnings, financial condition, capital requirements, applicable regulations and other factors, including the timeliness and adequacy of rate increases, will determine both our ability to pay dividends and the amount of those dividends. There can be no assurance that we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.

If we are unable to pay the principal and interest on our indebtedness as it comes due or we default under certain other provisions of our loan documents, our indebtedness could be accelerated and our results of operations and financial condition could be adversely affected.

Our ability to pay the principal and interest on our indebtedness as it comes due will depend upon our current and future performance. Our performance is affected by many factors, some of which are beyond our control.

We believe cash generated from operations and, if necessary, borrowings under existing credit facilities, will be sufficient to enable us to make our debt payments as they become due. If, however, we do not generate sufficient cash, we may be required to refinance our obligations or sell additional equity, which may be on terms that are less favorable than we desire.

No assurance can be given that any refinancing or sale of equity will be possible when needed, or that we will be able to negotiate acceptable terms. In addition, our failure to comply with certain provisions contained in our

Index

trust indentures and loan agreements relating to our outstanding indebtedness could lead to a default under these documents, which could result in an acceleration of our indebtedness.

We depend significantly on the technical and management services of our senior management team, and the departure of any of those persons could cause our operating results to temporarily be short of our expectations.

Our success depends significantly on the continued individual and collective contributions of our senior management team. If we lose the services of any member of our senior management, or are unable to attract and retain qualified senior management personnel, our operating results could be negatively impacted.

We are subject to anti-takeover measures that may be used to discourage, delay or prevent changes of control that might benefit non-management shareholders.

Subsection 10A of the New Jersey Business Corporation Act, known as the New Jersey Shareholders Protection Act, applies to us. The Shareholders Protection Act deters merger proposals, tender offers or other attempts to effect changes in control that are not approved by our Board of Directors. In addition, we have a classified Board of Directors, which means only a portion of the Director population is elected each year. A classified Board can make it more difficult for an acquirer to gain control of the Company by voting its candidates onto the Board of Directors and may also deter merger proposals and tender offers. Our Board of Directors also has the ability, subject to obtaining NJBPU approval, to issue one or more series of preferred stock having such number of shares, designation, preferences, voting rights, limitations and other rights as the Board of Directors may fix. This could be used by the Board of Directors to discourage, delay or prevent an acquisition that the Board of Directors determines is not in the best interest of the common stockholders.

Middlesex Water Company (Middlesex) has operated as a water utility in New Jersey since 1897, in Delaware through our wholly-owned subsidiary, Tidewater Utilities, Inc. (Tidewater), since 1992 and in Pennsylvania through our wholly-owned subsidiary, Twin Lakes Utilities, Inc. (Twin Lakes), since 2009. We are in the business of collecting, treating and distributing water for domestic, commercial, municipal, industrial and fire protection purposes. We also operate two New Jersey municipal water and wastewater systems under contract and provide regulated wastewater services in New Jersey and Delaware through our subsidiaries. We are regulated as to rates charged to customers for water and wastewater services, as to the quality of water service we provide and as to certain other matters in New Jersey, Delaware and Pennsylvania. Only our Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy), Inc. (USA-PA) and White Marsh Environmental Services, Inc. (White Marsh) subsidiaries are not regulated utilities.

Index

Our New Jersey water utility system (the Middlesex System) provides water services to approximately 61,000 retail customers, primarily in central New Jersey. The Middlesex System also provides water service under contract to municipalities in central New Jersey with a total population of approximately 219,000. We also have an investment in a joint venture, Ridgewood Green RME (RGRME), that operates facilities to optimize the production of electricity at the Village of Ridgewood, New Jersey wastewater treatment plant and other municipal facilities. In partnership with our subsidiary, USA-PA, we operate the water supply system and wastewater system for the City of Perth Amboy, New Jersey (Perth Amboy). Our Bayview subsidiary provides water services in Downe Township, New Jersey. Our other New Jersey subsidiaries, Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), provide water and wastewater services to approximately 2,500 customers in Southampton Township, New Jersey.

USA operates the Borough of Avalon, New Jersey’s (Avalon) water utility, sewer utility and storm water system under a ten-year operations and maintenance contract expiring in 2022. In addition to performing day to day operations, USA is responsible for billing, collections, customer service, emergency responses and management of capital projects funded by Avalon. Under a marketing agreement with HomeServe USA (HomeServe), USA offers residential customers in New Jersey and Delaware a menu of water and wastewater related home maintenance programs. HomeServe is a leading national provider of such home maintenance service programs. USA receives a service fee for the billing, cash collection and other administrative matters associated with HomeServe’s service contracts. The agreement expires in 2021. USA also provides unregulated water and wastewater services under contract with several New Jersey municipalities.

Our Delaware subsidiaries, Tidewater and Southern Shores Water Company, LLC (Southern Shores), provide water services to approximately 43,000 retail customers in New Castle, Kent and Sussex Counties, Delaware. Tidewater’s subsidiary, White Marsh, services approximately 4,000 customers in Kent and Sussex Counties through various operations and maintenance contracts.

Our Pennsylvania subsidiary, Twin Lakes, provides water services to approximately 120 retail customers in the Township of Shohola, Pike County, Pennsylvania.

Recent Developments

Pinelands Water, Pinelands Wastewater and Twin Lakes Rate Increases – In the second quarter of 2016, Pinelands Water, Pinelands Wastewater and Twin Lakes implemented base rate increases of $0.2 million, $0.1 million and $0.1 million, respectively. The rate increases were necessitated by capital infrastructure investments the companies have made and increased operations and maintenance costs. The Pinelands Water and Twin Lakes rate increases will be phased-in over two years.

Tidewater Distribution System Improvement Charge (DSIC) - Effective January 1, 2017, Tidewater increased its Delaware Public Service Commission (DEPSC)-approved DSIC rate, which is expected to generate $0.3 million of annual revenues. A DSIC is a rate-mechanism that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements made between base rate proceedings.

Strategy for Growth

Our strategy for profitable growth is focused on five key areas:

Prudent acquisitions of investor- and municipally-owned water and wastewater utilities;

Timely and adequate recovery of prudent investments in utility plant required to maintain appropriate utility services;

Operate municipal, commercial and industrial water and wastewater systems under contract;

Index

Invest in renewable energy projects that are complementary to the provision of water and wastewater services, and to our core water and wastewater competencies; and

Invest in other products, services and opportunities that complement our core water and wastewater competencies.

Rates

Middlesex - In August 2015, Middlesex’s Petition to the New Jersey Board of Public Utilities (the NJBPU) seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $5.0 million. The new base water rates were needed to recover increased costs and lost customer revenues, as well as a return on invested capital in rate base of $219.0 million, based on a return on equity of 9.75%. The rate increase became effective on August 29, 2015.

On November 1, 2016, Middlesex implemented an NJBPU-approved purchased water adjustment clause sufficient to recover additional costs of less than $0.1 million for the purchase of treated water from a non-affiliated regulated water utility.

Tidewater - In August 2014, Tidewater’s Application to the DEPSC seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $0.8 million. The new base water rates were designed to recover increased costs and a return on invested capital in rate base of $208.6 million, based on a return on equity of 9.75%. The rate increase became effective on August 19, 2014.

Effective January 1, 2017, Tidewater increased its DEPSC-approved DSIC rate, which is expected to generate revenues of approximately $0.3 million annually.

TESI - In October 2014, TESI implemented a DEPSC-approved 33.5% base wastewater rate increase for residential customers in the Plantations development in Delaware (approximately $0.1 million annually).

Pinelands - In April 2016, the NJBPU approved $0.2 million and $0.1 million of increases, respectively, in Pinelands Water and Pinelands Wastewater’s annual base rates, effective May 7, 2016. In October 2015, the companies had filed petitions with the NJBPU seeking permission to increase base rates by approximately $0.5 million per year. The rate filings were necessitated by capital infrastructure investments the companies have made, or have committed to make, increased operations and maintenance costs and lower non-fixed fee revenues. The Pinelands Water base water rate increase will be phased-in over two years.

Southern Shores - Under the terms of a multi-year DEPSC-approved agreement expiring in 2020, customer rates will increase on January 1^st of each year to generate additional annual revenue of $0.1 million with each increase.

Twin Lakes - In June 2016, the Pennsylvania Public Utilities Commission approved a $0.1 million increase in Twin Lakes’ base water rates, effective June 15, 2016. In November 2015, Twin Lakes had filed a petition seeking permission to increase its base water rates by approximately $0.2 million per year. This request was necessitated by capital infrastructure investments Twin Lakes has made, or committed to make, and increased operations and maintenance costs. The rate increase will be phased in over two years.

Outlook

Our ability to increase operating income and net income is based significantly on four factors: weather, adequate and timely rate relief, effective cost management, and customer growth (which are evident in comparison discussions in the Results of Operations section below). Weather patterns experienced in 2015 and 2016, which contributed to overall increases in operating revenues, may not reoccur in 2017. Changes in customer water usage habits, as well as increases in capital expenditures and operating costs, are significant factors in determining the timing and extent of rate increase requests. As operating costs are anticipated to increase in 2017 in a variety of categories, we continue to implement plans to further streamline operations and further reduce, and mitigate increases in, operating costs.

Organic residential customer growth for 2017 is expected to be consistent with that experienced in recent years.

The Company has projected to spend approximately $223 million on its 2017-2019 capital investment program, including approximately $36 million to construct a large-diameter transmission pipeline that will provide a second connection between Middlesex’s main water treatment plant and distribution system in New Jersey, $34 million on our RENEW Program, our ongoing initiative to eliminate unlined mains in the Middlesex System and $27 million for the upgrade of Middlesex’s main water treatment plant in New Jersey.

Operating Results by Segment

The Company has two operating segments, Regulated and Non-Regulated. Our Regulated segment contributed approximately 89%, 88% and 88% of total revenues for the years ended December 31, 2016, 2015 and 2014, respectively and approximately 98%, 94% and 93% of net income for the years ended December 31, 2016, 2015 and 2014, respectively. The discussion of the Company’s results of operations is on a consolidated basis, and includes significant factors by subsidiary. The segments in the tables included below are comprised of the following companies: Regulated- Middlesex, Tidewater, Pinelands, Southern Shores, TESI and Twin Lakes; Non-Regulated- USA, USA-PA, and White Marsh.

Index

Operating Revenues

Operating revenues for the year ended December 31, 2016 increased $6.9 million from the same period in 2015. This increase was primarily related to the following factors:

Middlesex System revenues increased $5.9 million due to:

Sales to General Metered Service and Public/Private Fire customers increased by $4.4 million from a NJBPU-approved rate increase implemented in August 2015 ($3.2 million) and favorable weather conditions ($1.2 million); and

Sales to Contract customers increased by $1.5 million due to higher water demand ($1.4 million) and from a NJBPU-approved rate increase implemented in August 2015 ($0.1 million);

Tidewater System revenues increased $0.6 million primarily due to additional customers;

White Marsh revenues increased $0.2 million due to new contracts to operate water and wastewater systems as well as additional billable supplemental services under existing contracts; and

Pinelands revenues increased $0.2 million due to the NJBPU-approved rate increase implemented in May 2016 and weather-related demand.

Operation and Maintenance Expense

Operation and maintenance expenses for the year ended December 31, 2016 increased $0.4 million from the same period in 2015, primarily related to the following factors:

Labor costs increased by $1.6 million due to company-wide higher average labor rates, increased headcount and incentive compensation partially offset by higher capitalized labor at Middlesex;

Costs associated with Middlesex’s large main condition assessment program increased $0.3 million;

Insurance costs increased $0.3 million primarily due to higher workmen’s compensation premiums;

Employee benefit expenses decreased by $1.3 million due primarily to lower retirement plan costs. The 2016 costs were calculated using a higher discount rate than in the 2015 calculation of our net periodic plan costs;

Decreased main break repair activity, as compared to 2015, resulted in lower costs of $0.2 million in our Middlesex System;

Variable production costs decreased $0.2 million, due primarily to improved non-revenue water management and higher raw water quality in our Middlesex System; and

All other operation and maintenance expense categories decreased $0.1 million.

Depreciation

Depreciation expense for the year ended December 31, 2016 increased $0.7 million from the same period in 2015 due to a higher level of utility plant in service.

Other Taxes

Other taxes for the year ended December 31, 2016 increased $1.0 million from the same period in 2015, primarily due to higher gross revenue taxes on increased Middlesex system revenues.

Other Income (Expense), net

Other income (expense), net for the year ended December 31, 2016 decreased $1.2 million from the same period in 2015, due primarily to a $1.9 million charge in connection with Middlesex’s joint venture equity investment in, and loan to, RGRME. RGRME owns and operates a renewable energy system solution comprised of an anaerobic digester, biogas generator and several solar panel sites for the Village of Ridgewood, New Jersey (Ridgewood). RGRME earns revenues primarily by selling renewable sourced electricity to Ridgewood and charging fees for liquid waste disposal. During the fourth quarter of 2016, RGRME identified that significant additional investment was required to optimize the liquid waste disposal and biogas electric generation process.

Index

Middlesex concluded that RGRME’s inability to effectively operate the renewable energy system without significant additional investment would impair its ability to generate enough cash flow to cover its current and future operating and debt service obligations. Middlesex recorded an allowance for uncollectible notes receivable for $1.7 million and an impairment charge of $0.2 million on its equity investment. Offsetting some of the these losses was the recognition by USA of previously deferred income associated with the 10-year marketing agreement with HomeServe and higher allowance for funds used during construction due to higher construction expenditures.

Interest Charges

Interest charges for the year ended December 31, 2016 decreased $0.3 million from the same period in 2015 due to lower average long-term and short-term debt balances outstanding.

Income Taxes

Income taxes for the year ended December 31, 2016 increased $1.2 million from the same period in 2015, primarily due to higher taxable income in 2016 as compared to 2015.

Net Income and Earnings Per Share

Net income for the year ended December 31, 2016 increased $2.7 million as compared with the same period in 2015. Basic and diluted earnings per share were $1.39 and $1.38 for the year ended December 31, 2016 and 2015, as compared to $1.23 and $1.22, respectively, for the same period in 2015.

Operating Revenues

Operating revenues for the year ended December 31, 2015 increased $8.9 million from the same period in 2014 due to the following factors:

Middlesex System revenues increased $5.6 million due to NJBPU-approved rate increases implemented in July 2014 (approximately $2.2 million) and August 2015 (approximately $1.6 million) and higher weather-driven customer demand (approximately $1.8 million);

Tidewater System revenues increased $1.8 million due to higher demand from existing customers and the October 2014 acquisition of the Dover Air Force Base system;

Index

USA-PA’s revenues increased $0.8 million from scheduled fixed fees increases under our contract with Perth Amboy ($1.0 million) partially offset by lower revenues ($0.2 million) under the same contract for supplemental services;

TESI’s revenues increased $0.3 million due primarily to base wastewater rate increases effective in October 2014 and April 2015;

USA’s revenues increased $0.2 million due to a higher amount of billable supplemental services under our contract to operate the Avalon water, wastewater and storm water system (see corresponding expense increase in “Operation and Maintenance Expense” below); and

All other revenues increased $0.2 million.

Operation and Maintenance Expenses

Operation and maintenance expenses for the year ended December 31, 2015 increased $6.0 million from the same period in 2014 due to the following factors:

Employee benefit expenses increased $3.4 million due to higher employee healthcare insurance costs and higher retirement plan costs resulting from a lower discount rate than in the prior year and the required adoption of new mortality tables, reflecting longer life expectancies. Both factors impacted the calculation of the 2015 net periodic plan costs;

Variable production costs increased $0.9 million due to an increase in the rate the Company pays for residuals removal in our Middlesex System and increased production in our Middlesex and Tidewater systems;

USA-PA’s operation and maintenance costs increased $0.9 million due mostly to higher subcontractor expenditures (see corresponding increase in “Operating Revenues” above);

USA’s operation and maintenance costs increased $0.6 million due to expenditures for billable supplemental services under USA’s contract to operate the Avalon water, sewer and storm water systems (see corresponding revenue increase in “Operating Revenues” above); and

All other operation and maintenance expense categories increased $0.2 million.

Depreciation

Depreciation expense for the year ended December 31, 2015 increased $0.6 million from the same period in 2014 due to a higher level of utility plant in service.

Other Taxes

Other taxes for the year ended December 31, 2015 increased $0.8 million from the same period in 2014 due to higher revenue related taxes on increased revenues in our Middlesex system.

Other Income, net

Other Income, net for the year ended December 31, 2015 increased $0.7 million from the same period in 2014 due higher allowance for funds used during construction, resulting from a higher level of capital projects in progress, and lower business development costs at our TESI subsidiary.

Interest Charges

Interest charges for the year ended December 31, 2015 decreased $0.1 million from the same period in 2014 due to lower average interest rates on decreased average total debt outstanding.

Income Taxes

Income taxes for the year ended December 31, 2015 increased $0.6 million from the same period in 2014 due to increased pre-tax operating income in 2015 as compared to 2014.

Index

Net Income and Earnings Per Share

Net income for the year ended December 31, 2015 increased $1.6 million as compared with the same period in 2014. Basic and diluted earnings per share increased to $1.23 and $1.22, respectively, for the year ended December 31, 2015, as compared to $1.14 and $1.13, respectively, for the year ended December 31, 2014.

Liquidity and Capital Resources

Cash Flows from Operating Activities

Cash flows from operating activities are largely influenced by four factors: weather, adequate and timely rate increases, effective cost management and customer growth. The effect of those factors on net income is discussed in the Results of Operations section above.

For the year ended December 31, 2016, cash flows from operating activities were $47.1 million, which enabled us to internally fund approximately 75% of utility plant expenditures in 2016. This was a decrease in cash flows of $4.1 million from 2015 and resulted primarily from higher payments for income tax and materials and supplies partially offset by higher water sales and timing of payments to vendors.

For the year ended December 31, 2015, cash flows from operating activities increased $18.6 million to $51.2 million. The increase in cash flows from operating activities resulted from a net refund of previously paid federal income taxes resulting from the Company’s adoption of final IRS regulations pertaining to the deductibility of costs that qualify as repairs on tangible property (approximately $8.8 million), income taxes paid and higher net income. The $51.2 million of net cash flow from operations enabled us to internally fund all utility plant expenditures incurred in 2015.

Increases in certain operating costs impact our liquidity and capital resources. We continually monitor the need for timely rate filing to minimize the lag between the time we experience increased operating costs and capital expenditures and the time we receive appropriate rate relief. There can be no assurances however that our regulated subsidiaries’ respective Utility Commissions will approve base water and/or wastewater rate increase requests in whole or in part or when the decisions will be rendered.

Cash Flows Used in Investing Activities

For the year ended December 31, 2016, cash flows used in investing activities increased $23.0 million to $47.4 million, which was attributable to higher utility plant expenditures.

For the year ended December 31, 2015, cash flows used in investing activities increased $2.5 million to $24.4 million. The increase in cash flows used in investing activities resulted from increased utility plant expenditures partially offset by increased restricted cash inflows.

For further discussion on the Company’s future capital expenditures and expected funding sources, see “Capital Expenditures and Commitments” below.

Cash Flows Used in Financing Activities

For the year ended December 31, 2016, cash flows from financing activities positively increased $26.7 million to $0.7 million. The majority of the increase in cash flows provided by financing activities is due to the net increase in short-term debt funding.

For the year ended December 31, 2015, cash flows used in financing activities increased $13.1 million to $26.0 million. The increase in cash flows used in financing activities resulted from increased short-term debt refunding and lower net cash inflows from long-term debt, as the Company did not require any additional New Jersey State Revolving Fund (SRF) long-term financing in 2015.

For further discussion on the Company’s short-term and long-term debt, see “Sources of Liquidity” below.

Index

Capital Expenditures and Commitments

To fund our capital program, we use internally generated funds, short term and long term debt borrowings, proceeds from sales of common stock under the Middlesex Water Company Investment Plan (Investment Plan) and, when market conditions are favorable, proceeds from sales offerings to the public of our common stock.

The table below summarizes our estimated capital expenditures for the years 2017-2019.

	(Millions)
	2017		2018		2019		2017-2019
Distribution/Network System	$	39.2	$	49.9	$	45.8	$	134.9
Production System		11.6		32.1		20.6		64.3
Information Technolgy (IT) Systems		3.8		0.5		0.7		5.0
Other		5.6		6.4		6.7		18.7
Total Estimated Capital Expenditures	$	60.2	$	88.9	$	73.8	$	222.9

Our estimated capital expenditures for the items listed above are primarily comprised of the following:

Distribution/Network System-Projects associated with installation and relocation of water mains and service lines and wastewater collection systems, construction of water storage tanks, installation and replacement of hydrants and meters and our RENEW Program. RENEW is our ongoing initiative to eliminate unlined mains in the Middlesex System. In connection with our RENEW Program, we expect to spend approximately $11.8 million in 2017 and $11.2 million in both 2018 and 2019. Construction of a large-diameter transmission pipeline that will provide a second connection between Middlesex’s Carl J. Olsen (CJO) water treatment plant and our distribution system is expected to result in approximately $35.5 million of expenditures beginning in 2017 through 2019.

Production System-Projects associated with our water production and water/wastewater treatment plants, including expenditures of approximately $2.8 million in 2017 for the upgrade of a booster station at one of Middlesex’s well fields and approximately $27.0 million of expenditures beginning in 2017 through 2019 for the upgrade of the CJO water treatment plant.

IT Systems-Upgrade of our enterprise resource planning system and hardware and software purchases for our other IT systems.

Other-Purchase of transportation equipment, tools, furniture, laboratory equipment, security systems and other general infrastructure needs.

The actual amount and timing of capital expenditures is dependent on the need for replacement of existing infrastructure, customer growth, residential new home construction and sales, project scheduling and continued refinement of project scope and costs.

To pay for our capital program in 2017, we plan on utilizing:

Internally generated funds;

Proceeds from the Investment Plan;

Proceeds from the 2016 and 2017 New Jersey SRF program (approximately $19.0 million depending on construction timing). SRF programs provide low cost financing for projects that meet certain water quality and system improvement benchmarks (see discussion under “Sources of Liquidity-Long-term Debt” below) ; and

Short-term borrowings, as needed, through $60.0 million of available lines of credit with several financial institutions. As of December 31, 2016, there remains $48.0 million of available credit under these lines.

Index

Sources of Liquidity

Short-term Debt. The Company had established lines of credit aggregating $60.0 million throughout 2016. At December 31, 2016, the outstanding borrowings under these credit lines were $12.0 million, at a weighted average interest rate of 1.71%.

The weighted average daily amounts of borrowings outstanding under the Company’s credit lines and the weighted average interest rates on those amounts were $7.4 million and $15.3 million at 1.54% and 1.19% for the years ended December 31, 2016 and 2015, respectively.

Long-term Debt. Subject to regulatory approval, the Company periodically issues long-term debt to fund its investments in utility plant and other assets. To the extent possible, the Company finances qualifying capital projects under SRF loan programs in New Jersey and Delaware. These government programs provide financing at interest rates that are typically below rates available in the broader financial markets. A portion of the borrowings under the New Jersey SRF is interest-free.

Under the New Jersey SRF program, borrowers first enter into a construction loan with the New Jersey Environmental Infrastructure Trust (NJEIT) at a below market interest rate. The current interest rate on construction loan borrowings is zero percent (0%). When construction on the qualifying project is substantially complete, the NJEIT will coordinate the conversion of the construction loan into a long-term securitized loan with a portion of the principal balance having a stated interest rate of zero percent (0%) and a portion of the principal balance at a market interest rate at the time of closing using the credit rating of the State of New Jersey. The current term of the long-term loans offered through the NJEIT is up to thirty years. The current portion of the principal balance having a stated interest rate of zero percent (0%) is 75% with the remaining portion of 25% having a market based interest rate. The NJEIT generally schedules its long-term debt financings in May and November.

In January 2017, the NJBPU approved Middlesex’s request to borrow up to $37.0 million under the New Jersey SRF program to fund the construction of a large-diameter transmission pipeline from the CJO water treatment plant and interconnect with our distribution system. Middlesex expects to close on the SRF construction loan in 2017 with proceeds requisitions occurring throughout 2017, 2018 and 2019.

In January 2017, the NJBPU approved Middlesex’s request to borrow up to $10.0 million under the New Jersey SRF program to fund the 2017 RENEW Program, which is an ongoing initiative to eliminate all unlined water distribution mains in the Middlesex system. Middlesex expects to close on the SRF construction loan in 2017 with proceeds requisitions occurring throughout 2017.

In July 2016, the NJBPU approved Middlesex’s request to borrow up to $4.0 million under the New Jersey SRF program to fund the upgrade of a booster station at one of its well fields. Middlesex expects to close on the SRF construction loan in 2017 with proceeds requisitions occurring through September 2017.

In March 2016, the NJBPU approved Middlesex’s request to borrow up to $16.0 million under the New Jersey SRF program to fund the 2016 RENEW Program. Middlesex closed on an $11.8 million zero percent (0%) SRF construction loan on June 28, 2016. Through December 31, 2016, Middlesex has drawn down $7.5 million and expects to draw down the remaining proceeds during the first quarter of 2017. The NJEIT notified the Company that it has scheduled this project to be included in the May 2017 long-term loan financing.

In February 2016, Tidewater closed on a $1.2 million General Obligation Note loan with the Delaware SRF program to fund the replacement of the water distribution system in a manufactured home community. Tidewater has drawn $1.1 million on this loan and the project is considered complete. The interest rate on the $1.1 million is 2.0% with a final repayment maturity date of February 1, 2036.

interest rate transaction, but which was switched to a fixed rate of 4.47% in January 2017. The proceeds were used to pay down short-term debt and for other general corporate purposes. The final maturity date of all borrowings under this loan agreement is April 2040.

Substantially all of the Utility Plant of the Company is subject to the lien of its mortgage, which includes debt service and capital ratio covenants. The Company is in compliance with all of its mortgage covenants and restrictions.

Common Stock. The Company periodically issues shares of common stock in connection with the Investment Plan. The Company raised $1.5 million through the issuance of 42,604 shares under the Investment Plan during 2016. In July 2015, the Company registered an additional 700,000 common shares for potential issuance under the Investment Plan with the United States Securities and Exchange Commission, increasing the number of NJBPU-authorized shares to 3.0 million.

Contractual Obligations

In the course of normal business activities, the Company enters into a variety of contractual obligations and commercial commitments. Some of these result in direct obligations on the Company’s balance sheet while others are commitments, some firm and some based on uncertainties, which are disclosed in the Company’s consolidated financial statements.

The table below presents our known contractual obligations for the periods specified as of December 31, 2016.

The table above does not reflect any anticipated cash payments for postretirement benefit plan obligations. The effect on the timing and amount of these payments resulting from potential changes in actuarial assumptions and returns on plan assets cannot be estimated. In 2016, the Company contributed $5.2 million to its postretirement benefit plans and expects to contribute approximately $4.9 million in 2017. In addition, the table above does not reflect the provision against refundable taxes of $2.3 million related to the Company’s adoption of IRS tangible property repair cost regulations due to the uncertainty of future cash flows (see Note 3 of the Notes to Consolidated Financial Statements for further discussion).

Critical Accounting Policies and Estimates

The application of accounting policies and standards often requires the use of estimates, assumptions and judgments. The Company regularly evaluates these estimates, assumptions and judgments, including those related to the calculation of pension and postretirement benefits, unbilled revenues, and the recoverability of certain assets, including regulatory assets. The Company bases its estimates, assumptions and judgments on historical experience and current operating environment. Changes in any of the variables that are used for the Company’s estimates, assumptions and judgments may lead to significantly different financial statement results.

Index

Our critical accounting policies are set forth below.

Regulatory Accounting

We maintain our books and records in accordance with accounting principles generally accepted in the United States of America. Middlesex and certain of its subsidiaries, which account for approximately 89% of Operating Revenues and 99% of Total Assets, are subject to regulation in the states in which they operate. Those companies are required to maintain their accounts in accordance with regulatory authorities’ rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 980 Regulated Operations (Regulatory Accounting).

In accordance with Regulatory Accounting, costs and obligations are deferred if it is probable that these items will be recognized for rate-making purposes in future rates. Accordingly, we have recorded costs and obligations, which will be amortized over various future periods. Any change in the assessment of the probability of rate-making treatment will require us to change the accounting treatment of the deferred item. We have no reason to believe any of the deferred items that are recorded will be treated differently by the regulators in the future.

Revenues

Revenues from metered customers include amounts billed on a cycle basis and unbilled amounts estimated from the last meter reading date to the end of the accounting period. The estimated unbilled amounts are determined by utilizing factors which may include historical consumption usage, current weather patterns and economic conditions. Differences between estimated revenues and actual billings are recorded in a subsequent period.

Revenues from unmetered customers are billed at a fixed tariff rate in advance at the beginning of each service period and are recognized in revenue ratably over the service period.

Revenues from the Perth Amboy management contract are comprised of fixed and variable fees. Fixed fees, which have been set for the life of the contract, are billed monthly and recorded as earned. Variable fees, which are based on billings and other factors, are recorded upon approval of the amount by Perth Amboy. The variable fees are not a material component of the management contract.

Revenues from USA’s operations and maintenance contract for the Avalon water utility, sewer utility and storm water system are fixed for the life of the contract, are billed monthly and recorded as earned. USA also provides services to Avalon in addition to the base services provided under the operation and maintenance contract. These additional services are recorded as earned and billed upon approval of Avalon.

Retirement Benefit Plans

We maintain a noncontributory defined benefit pension plan (Pension Plan) which covers all currently active employees who were hired prior to April 1, 2007. In addition, the Company maintains an unfunded supplemental plan for its executive officers.

The Company has a retirement benefit plan other than pensions (Other Benefits Plan) for substantially all of its retired employees. Employees hired after March 31, 2007 are not eligible to participate in the Other Benefits Plan. Coverage includes healthcare and life insurance.

The costs for providing retirement benefits are dependent upon numerous factors, including actual plan experience and assumptions of future experience. Future retirement benefit plan obligations and expense will depend on future investment performance, changes in future discount rates and various other demographic factors related to the population participating in the Company’s retirement benefit plans, all of which can change significantly in future years.

Index

The allocation by asset category of retirement benefit plan assets at December 31, 2016 and 2015 is as follows:

	Pension Plan									Other Benefits Plan
Asset Category	2016			2015			Target			2016			2015			Target
Equity Securities		59.7	%		59.1	%		55	%		54.1	%		50.0	%		43	%
Debt Securities		36.6	%		37.8	%		38	%		43.3	%		47.4	%		50	%
Cash		1.0	%		1.3	%		2	%		2.6	%		2.4	%		2	%
Real Estate/Commodities		2.7	%		1.8	%		5	%		0.0	%		0.2	%		5	%
Total		100.0	%		100.0	%					100.0	%		100.0	%

The primary assumptions used for determining future postretirement benefit plans’ obligations and costs are as follows:

Discount Rate - calculated based on market rates for long-term, high-quality corporate bonds specific to the expected duration of our Pension Plan and Other Benefits Plan’s liabilities;

Compensation Increase - based on management projected future employee compensation increases;

Long-Term Rate of Return - determined based on expected returns from our asset allocation for our Pension Plan and Other Benefits Plan assets;

Mortality –The Company utilizes the Society of Actuaries’ mortality table (RP 2014) (Mortality Improvement Scale MP2016 for the 2016 valuation); and

Healthcare Cost Trend Rate - based on management projected future healthcare costs.

The discount rate, compensation increase rate and long-term rate of return used to determine future obligations of our postretirement benefit plans as of December 31, 2016 are as follows:

	Pension Plan	Other Benefits Plan
Discount Rate	4.06%	4.06%
Compensation Increase	3.00%	3.00%
Long-term Rate of Return	7.50%	7.50%

For the 2016 valuation, costs and obligations for our Other Benefits Plan assumed a 9.0% annual rate of increase in the per capita cost of covered healthcare benefits in 2017 with the annual rate of increase declining 1.0% per year for 2018-2020 and 0.5% per year for 2021-2022, resulting in an annual rate of increase in the per capita cost of covered healthcare benefits of 5% by year 2022.

The following is a sensitivity analysis for certain actuarial assumptions used in determining projected benefit obligations (PBO) and expenses for our postretirement benefit plans:

Pension Plan

Actuarial Assumptions	Estimated Increase/ (Decrease) on PBO (000s)			Estimated Increase/ (Decrease) on Expense (000s)
Discount Rate 1% Increase	$	(10,873	)	$	(1,074	)

ITEM 7A.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK.

We are exposed to market risk associated with changes in interest rates and commodity prices. The Company is subject to the risk of fluctuating interest rates in the normal course of business. Our policy is to manage interest rates through the use of fixed rate long-term debt and, to a lesser extent, variable rate long-term and short-term debt. The Company’s interest rate risk related to existing fixed rate, long-term debt is not material due to the term of the majority of our First Mortgage Bonds, which have final maturity dates ranging from 2018 to 2047. Over the next twelve months, approximately $6.2 million of the current portion of existing long-term debt instruments will mature. The Company manages its interest rate risk related to existing variable-rate long-term and short-term debt by limiting our variable rate exposure. Applying a hypothetical change in the rate of interest charged by 10% on those fixed- and variable-rate borrowings would not have a material effect on our earnings.

Our risks associated with commodity price increases for chemicals, electricity and other commodities are reduced through contractual arrangements and the ability to recover price increases through rates. Non-performance by these commodity suppliers could have a material adverse impact on our results of operations, financial position and cash flows.

We are exposed to credit risk for both our Regulated and Non-Regulated business segments. Our Regulated operations serve residential, commercial, industrial and municipal customers while our Non-Regulated operations engage in business activities with developers, government entities and other customers. Our primary credit risk is exposure to customer default on contractual obligations and the associated loss that may be incurred due to the non-payment of customer accounts receivable balances. Our credit risk is managed through established credit and collection policies which are in compliance with applicable regulatory requirements and involve monitoring of customer exposure and the use of credit risk mitigation measures such as letters of credit or prepayment arrangements. Our credit portfolio is diversified with no significant customer or industry concentrations. In addition, our Regulated businesses are generally able to recover all prudently incurred costs including uncollectible customer accounts receivable expenses and collection costs through rates.

The Company's retirement benefit plan assets are exposed to the market price variations of debt and equity securities. Changes to the Company's retirement benefit plan assets’ value can impact the Company's retirement benefit plan expense, funded status and future minimum funding requirements. Our risk is reduced through our ability to recover retirement benefit plan costs through rates.

MIDDLESEX WATER COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Organization, Summary of Significant Accounting Policies and Recent Developments

(a) Organization - Middlesex Water Company (Middlesex) is the parent company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Tidewater Environmental Services, Inc. (TESI), Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy) Inc. (USA-PA) and Twin Lakes Utilities, Inc. (Twin Lakes). Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh) are wholly-owned subsidiaries of Tidewater.

Middlesex Water Company has operated as a water utility in New Jersey since 1897, in Delaware, through our wholly-owned subsidiary, Tidewater, since 1992 and in Pennsylvania, through our wholly-owned subsidiary, Twin Lakes, since 2009. We are in the business of collecting, treating, distributing and selling water for domestic, commercial, municipal, industrial and fire protection purposes. We also operate New Jersey municipal water, wastewater and storm water systems under contract and provide unregulated water and wastewater services in New Jersey and Delaware through our subsidiaries. Our rates charged to customers for water and wastewater services, the quality of services we provide and certain other matters are regulated in New Jersey, Delaware and Pennsylvania by the New Jersey Board of Public Utilities (NJBPU), Delaware Public Service Commission (DEPSC) and Pennsylvania Public Utilities Commission (PAPUC), respectively. Our USA, USA-PA and White Marsh subsidiaries are not regulated utilities.

(b) Principles of Consolidation – The financial statements for Middlesex and its wholly-owned subsidiaries (the Company) are reported on a consolidated basis. All significant intercompany accounts and transactions have been eliminated. Other financial investments in which the Company holds a 50% or less voting interest and cannot exercise control over the operation and policies of the investments are accounted for under the equity method of accounting. Under the equity method of accounting, the Company records its investment interests in Non-Utility Assets and its percentage share of the earnings or losses of the investees in Other Income (Expense).

(c) System of Accounts – Middlesex, Pinelands Water and Pinelands Wastewater maintain their accounts in accordance with the Uniform System of Accounts prescribed by the NJBPU. Tidewater, TESI and Southern Shores maintain their accounts in accordance with DEPSC requirements. Twin Lakes maintains its accounts in accordance with PAPUC requirements.

(d) Regulatory Accounting - We maintain our books and records in accordance with accounting principles generally accepted in the United States of America. Middlesex and certain of its subsidiaries, which account for 89% of Operating Revenues and 99% of Total Assets, are subject to regulation in the state in which they operate. Those companies are required to maintain their accounts in accordance with regulatory authorities’ rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance provided in Accounting Standards Codification (ASC) 980, Regulated Operations.

In accordance with ASC 980, Regulated Operations, costs and obligations are deferred if it is probable that these items will be recognized for rate-making purposes in future rates. Accordingly, we have recorded costs and obligations, which will be amortized over various future periods. Any change in the assessment of the probability of rate-making treatment will require us to change the accounting treatment of the deferred item. We have no reason to believe any of the deferred items that are recorded will be treated differently by the regulators in the future. For additional information, see Note 2 – Rate and Regulatory Matters.

Index

(e) Retirement Benefit Plans - We maintain a noncontributory defined benefit pension plan (Pension Plan) which covers all active employees who were hired prior to April 1, 2007. In addition, the Company maintains an unfunded supplemental plan for its executive officers. The Company has a retirement benefit plan other than pensions (Other Benefits Plan) for substantially all of its retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance.

The Company’s costs for providing retirement benefits are dependent upon numerous factors, including actual plan experience and assumptions of future experience. Retirement benefit plan obligations and expense are determined based on investment performance, discount rates and various other demographic factors related to the population participating in the Company’s retirement benefit plans, all of which can change significantly in future years. For more information on the Company’s Retirement Benefit Plans, see Note 7 – Employee Benefit Plans.

(f) Utility Plant – Utility Plant is stated at original cost as defined for regulatory purposes. Property accounts are charged with the cost of betterments and major replacements of property. Cost includes direct material, labor and indirect charges for pension benefits and payroll taxes. The cost of labor, materials, supervision and other expenses incurred in making repairs and minor replacements and in maintaining the properties is charged to the appropriate expense accounts. At December 31, 2016, there was no event or change in circumstance that would indicate that the carrying amount of any long-lived asset was not recoverable.

(g) Depreciation – Depreciation is computed by each regulated member of the Company utilizing a rate approved by the applicable regulatory authority. The accumulated provision for depreciation is charged with the cost of property retired, less salvage. The following table sets forth the range of depreciation rates for the major utility plant categories used to calculate depreciation for the years ended December 31, 2016, 2015 and 2014. These rates have been approved by the NJBPU, DEPSC or PAPUC:

Source of Supply	1.15% - 3.44%	Transmission and Distribution (T&D):
Pumping	2.00% - 5.39%	T&D – Mains	1.10% - 3.13%
Water Treatment	1.65% - 7.09%	T&D – Services	2.12% - 3.16%
General Plant	2.08% - 17.84%	T&D – Other	1.61% - 4.63%
Wastewater Collection	1.42% - 1.81%

Non-regulated fixed assets consist primarily of office buildings, furniture and fixtures, and transportation equipment. These assets are recorded at original cost and depreciation is calculated based on the estimated useful lives, ranging from 3 to 40 years.

(h) Preliminary Survey and Investigation (PS&I) Costs – In the design of water and wastewater systems that the Company ultimately intends to construct, own and operate certain expenditures are incurred to advance those project activities. These PS&I costs are recorded as deferred charges on the balance sheet because these costs are expected to be recovered through future rates charged to customers as the underlying projects are placed into service as utility plant. If it is subsequently determined that costs for a project recorded as PS&I are not recoverable through rates charged to our customers, the applicable PS&I costs are recorded as Other Expense on the statement of income at that time.

(i) Customers’ Advances for Construction (CAC) – Utility plant and/or cash advances are provided to the Company by customers, real estate developers and builders in order to extend utility service to their properties. These transactions are recorded as CAC. Contractual Refunds of CACs in the form of cash are made by the Company and are based on either additional operating revenues generated from new customers or as new customers are connected to the respective system. After all refunds are made and/or contract terms have expired, any remaining balance is transferred to Contributions in Aid of Construction.

Index

Contributions in Aid of Construction (CIAC) – CIAC include direct non-refundable contributions of utility plant and/or cash and the portion of CAC that becomes non-refundable.

CAC and CIAC are not depreciated in accordance with regulatory requirements. In addition, these amounts reduce the investment base for purposes of setting rates.

(j) Allowance for Funds Used During Construction (AFUDC) - Middlesex and its regulated subsidiaries capitalize AFUDC, which represents the cost of financing projects during construction. AFUDC is added to the construction costs of individual projects exceeding specific cost and construction period thresholds established for each company and then depreciated along with the rest of the utility plant’s costs over its estimated useful life. AFUDC is calculated using each company’s weighted cost of debt and equity as approved in their most recent respective regulatory rate order. The AFUDC rates for the years ended December 31, 2016, 2015 and 2014 for Middlesex and Tidewater are as follows:

	2016		2015		2014
Middlesex		6.73%		6.72%		7.03%
Tidewater		7.92%		7.92%		7.91%

(k) Accounts Receivable – We record bad debt expense based on historical write-offs combined with an evaluation of current conditions. The allowance for doubtful accounts was $0.9 million and $0.8 million as of December 31, 2016 and 2015, respectively. For the years ended December 31, 2016, 2015 and 2014, bad debt expense was $0.7 million, $0.8 million and $0.7, respectively. For each of the years ended December 31, 2016, 2015 and 2014, write-offs were $0.6 million. Receivables not expected to be received in 2017 are included as non-current assets in Operations Contracts, Developer and Other Receivables, including a loan by Middlesex to Ridgewood Green RME (RGRME).

In 2011, Middlesex entered into a joint venture agreement that established the legal entity RGRME for the purpose of owning and operating a renewable energy facility at a municipal wastewater treatment plant in New Jersey. Construction was completed and the facility began operating in 2013. This public-private partnership includes the production of electricity from solar panels and biogas to meet the electric power needs of the municipal wastewater treatment plant. A major element of the project’s profitability is the ability to procure, and process, an adequate supply of high quality feedstock material from outside sources to supplement the production of biogas. Such feedstock is in the form of fats, oils, grease and other materials from various commercial operations. During the fourth quarter of 2016, RGRME determined that significant additional investment would need to be made to optimize the liquid waste disposal and biogas electricity generation process. As of December 31, 2016, Middlesex had an investment of $0.2 million of equity capital (included in “Non-utility Assets – Net”) and a $1.7 million loan to RGRME (included in “Operations Contracts, Developer and Other Receivables, net”). The Company has determined that it is more likely than not that RGRME will be unable to satisfy its remaining debt service obligation to Middlesex and therefore, an allowance for uncollectible notes receivable of $1.7 million has been recorded. Furthermore, Middlesex has recognized a noncash impairment charge of $0.2 million, representing the Middlesex’s equity investment in RGRME. These charges are included in “Other Expense” on the consolidated statement of income.

(l) Revenues - Retail customer invoices for regulated utility service are typically comprised of two components; a fixed service charge and a volumetric or consumption charge. Revenues from retail customers, except Tidewater fixed service charges, include amounts billed in arrears on a cycle basis and unbilled amounts estimated from the last meter reading date to the end of the accounting period. The estimated unbilled amounts are determined by utilizing factors which include historical volumetric or consumption usage and current climate and economic conditions. Actual billings may differ from our estimates. Tidewater customers are billed in advance for their fixed service charge and these revenues are recognized as the service is provided to the customer.

Southern Shores is an unmetered system. Customers are billed a fixed service charge in advance at the beginning of each month and revenues are recognized as earned.

Index

Customers in portions of the TESI system are billed a fixed service charge in arrears.

Revenues from White Marsh’s base water and wastewater system operating contracts are fixed, billed monthly and are recorded as earned. White Marsh also provides services in addition to the base services provided under its water and wastewater operating contracts, which are billed and recorded as earned.

Revenues from the City of Perth Amboy management contract are comprised of fixed and variable fees. Fixed fees, which have been set for the life of the contract, are billed monthly and recorded as earned. Variable fees are recorded upon approval of the amount by the City of Perth Amboy.

Revenues from USA’s operations and maintenance contract for the Borough of Avalon, New Jersey (Avalon) water utility, sewer utility and storm water system are fixed for the life of the contract, are billed monthly and recorded as earned. USA also provides services to Avalon in addition to the base services provided under the operation and maintenance contract. These additional services are recorded as earned and billed upon approval of Avalon.

(m) Unamortized Debt Expense and Premiums on Long-Term Debt - Unamortized Debt Expense and Premiums on Long-Term Debt, included on the consolidated balance sheet in long-term debt, are amortized over the lives of the related debt issues.

(n) Income Taxes - Middlesex files a consolidated federal income tax return for the Company and income taxes are allocated based on the separate return method. Investment tax credits have been deferred and are amortized over the estimated useful life of the related property. For more information on income taxes, see Note 3 – Income Taxes.

(o) Statements of Cash Flows - For purposes of reporting cash flows, the Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents represent bank balances and money market funds with investments maturing in less than 90 days.

(p) Restricted Cash – Restricted cash includes cash proceeds from loan transactions entered into through state financing programs and are held in trusts for debt service.

(q) Use of Estimates - Conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates.

(r) Recent Accounting Pronouncements

Consolidation - In February 2015, the Financial Accounting Standards Board (FASB) issued guidance that amends the consolidation analysis for variable interest entities (“VIEs”) as well as voting interest entities. The amendments under the new guidance modify the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities and eliminate the presumption that a general partner should consolidate a limited partnership. This guidance was effective January 1, 2016. The adoption of this guidance did not have a material impact on the Company’s financial statements.

Debt Issuance Costs - In April 2015, the FASB issued an update to authoritative guidance related to the presentation of debt issuance costs on the balance sheet, requiring companies to present debt issuance costs as a direct deduction from the carrying value of debt. The guidance was effective January 1, 2016. As a result of adopting this guidance, the December 31, 2015 balance sheet was revised, which resulted in decreases of $3.3 million to deferred charges and other assets and long-term debt, respectively. The adoption of this guidance had no impact on the Company’s statements of income or cash flows.

Deferred Income Taxes – In November 2015, the FASB issued guidance on the classification of deferred tax assets and deferred tax liabilities, requiring entities to present them as noncurrent on the balance sheet. This guidance was effective January 1, 2016 and did not have a material impact on the Company’s balance sheet.

Index

Inventory - In July 2015, the FASB issued guidance on simplifying the measurement of inventory. The new guidance replaces the current lower of cost or market test with a lower of cost or net realizable value test when cost is determined on a first-in, first-out or average cost basis. The guidance is effective January 1, 2017 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

Accounting for Share-Based Payments - In March 2016, the FASB issued guidance which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance is effective January 1, 2017. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

Revenue Recognition - In May 2014, the FASB issued an update to authoritative guidance related to revenue from contracts with customers. The update replaces most of the existing guidance with a single set of principles for recognizing revenue from contracts with customers. Additionally, the accounting for CIAC may be impacted if these contributions are determined to be revenue from contracts with customers. The FASB has deferred the effective date of these new revenue recognition standards by one year to January 1, 2018. The Company is currently analyzing the impact this standard will have on our financial statements and has begun creating an inventory of its contracts with customers, which consist primarily of regulated municipal water sale contracts and non-regulated operation and maintenance contracts for water and wastewater systems. Based on the Company’s initial interpretation of the guidance, this update is not expected to have an impact on the Company’s regulated municipal water sale contracts. The impact on the Company’s non-regulated operation and maintenance contracts, if any, is not expected to be material. The Company’s non-regulated segment contributed approximately 11% and 2% of total revenues and net income, respectively, for the year ended December 31, 2016. These assessments are preliminary and subject to change pending the Company’s completion of its review of the guidance and its impact on the Company’s contracts with customers, including the determination of whether or not CIAC is considered revenue from contracts with customers.

Recognition and Measurement of Financial Assets and Financial Liabilities - In January 2016, the FASB issued guidance which (i) requires all investments in equity securities, including other ownership interests such as partnerships, unincorporated joint ventures and limited liability companies, to be carried at fair value through net income, (ii) requires an incremental recognition and disclosure requirement related to the presentation of fair value changes of financial liabilities for which the fair value option has been elected, (iii) amends several disclosure requirements, including the methods and significant assumptions used to estimate fair value or a description of the changes in the methods and assumptions used to estimate fair value, and (iv) requires disclosure of the fair value of financial assets and liabilities measured at amortized cost at the amount that would be received to sell the asset or paid to transfer the liability. The guidance is effective for fiscal years beginning after December 15, 2017 with early adoption permitted. The guidance is required to be applied retrospectively with a cumulative effect adjustment to retained earnings for initial application of the guidance at the date of adoption (modified retrospective method). The Company is currently analyzing the impact this standard will have on our financial statements.

Leases - In February 2016, the FASB issued an update to authoritative guidance related to leases which will require lessees to recognize a lease liability (a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis) a right-of-use asset (an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term). The guidance is effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The Company is currently assessing the impact of this standard on its consolidated financial statements and footnote disclosures, but does not expect that the adoption of this guidance to have a material impact on the Company’s financial statements.

Statement of Cash Flows - In August 2016, the FASB issued guidance which amends the previous guidance on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of this guidance is to reduce the diversity in practice that has resulted from the lack of consistent principles on this

Index

topic. The guidance is effective January 1, 2018 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

Restricted Cash - In November 2016, the FASB issued an update to authoritative guidance related to the classification and presentation of restricted cash in the statement of cash flows, which requires entities to a) include restricted cash balances in its cash and cash-equivalent balances in the statement of cash flows and b) include a reconciliation of cash and cash-equivalents per the statement of financial position as compared to the statement of cash flows. Changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents will not be presented as cash flow activities in the statement of cash flows. In addition, an entity with a material balance of amounts described as restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The guidance is effective January 1, 2018 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

There are no other new adopted or proposed accounting guidance that the Company is aware of that could have a material impact on the Company’s financial statements.

Note 2 - Rate and Regulatory Matters

Rate Matters

Middlesex - In August 2015, Middlesex’s Petition to the NJBPU seeking permission to increase base water rates was concluded, based on a negotiated settlement, resulting in an increase in annual operating revenues of $5.0 million. The new base water rates were needed to recover increased costs and lost customer revenues, as well as a return on invested capital in rate base of $219.0 million, based on a return on equity of 9.75%. The rate increase became effective on August 29, 2015.

Effective January 1, 2017, Tidewater increased its DEPSC-approved Distribution System Improvement Charge (DSIC) rate, which is expected to generate revenues of approximately $0.3 million annually. A DSIC is a rate-mechanism that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements made between base rate proceedings.

Index

Regulatory Matters

We have recorded certain costs as regulatory assets because we expect full recovery of, or are currently recovering, these costs in the rates we charge customers. These deferred costs have been excluded from rate base and, therefore, we are not earning a return on the unamortized balances. These items are detailed as follows:

	(Thousands of Dollars)
	December 31,				Remaining
Regulatory Assets	2016		2015		Recovery Periods
Retirement Benefits	$	40,603	$	39,378	Various
Income Taxes		15,899		15,541	Various
Rate Cases, Tank Painting, and Other		4,392		3,633	2-10 years
Total	$	60,894	$	58,552

Retirement benefits include pension and other retirement benefits that have been recorded on the Consolidated Balance Sheet in accordance with the guidance provided in ASC 715, Compensation – Retirement Benefits. These amounts represent obligations in excess of current funding, which the Company believes will be fully recovered in rates set by the regulatory authorities.

The recovery period for income taxes is dependent upon when the temporary differences between the tax and book treatment of various items reverse.

The Company uses composite depreciation rates for its regulated utility assets, which is currently an acceptable method under generally accepted accounting principles and is widely used in the utility industry. Historically, under the composite depreciation method, the anticipated costs of removing assets upon retirement are provided for over the life of those assets as a component of depreciation expense. The Company recovers certain asset retirement costs through rates charged to customers as an approved component of depreciation expense. As of December 31, 2016 and 2015, the Company has approximately $11.3 million and $10.9 million, respectively, of expected costs of removal recovered currently in rates in excess of actual costs incurred as regulatory liabilities.

The Company is recovering through customer rates acquisition premiums totaling $0.5 million over the remaining lives of the underlying Utility Plant. These deferred costs have been included in rate base as utility plant and a return is being earned on the unamortized balances during the recovery periods.

As part of its 2014 Federal income tax return, the Company adopted the final IRS regulations pertaining to the tax deductibility of costs that qualify as repairs on tangible property. The adoption resulted in a net reduction of $17.6 million in taxes previously remitted to the IRS, for which the Company has already sought and received refunds pertaining to tax years 2012 through 2014 in accordance with IRS regulations. Subsequently, the Company’s 2014 federal income tax return was selected for examination by the IRS. Concurrently with the IRS examination, the Company agreed to extend the statutory review period for its 2012 tax year. It is unknown at this time whether the results of this examination will result in any changes to the filed 2014 tax return. While the

Index

Company believes that its treatment of qualifying tangible property repair costs is proper, its deductibility could be challenged as part of the current examination by the IRS. Therefore, the Company has recorded a provision against refundable taxes of $2.3 million.

It is probable that any net tax benefits that resulted from adopting the regulations will be considered in determining the revenue requirement used to set base rates for the Company in a future regulatory proceeding. Consequently, adoption of the new regulations did not and will not have a significant impact on the Company’s financial statements or effective tax rate.

The statutory review periods for income tax returns for the years prior to 2012 have been closed. In the event that there are interest and penalties associated with income tax adjustments in the current examination and future examinations, these amounts will be reported under interest expense and other expense, respectively. Other than the effects of the provision against refundable taxes discussed above, there are no unrecognized tax benefits resulting from prior period tax positions.

Note 4 - Commitments and Contingent Liabilities

Water Supply - Middlesex has an agreement with the New Jersey Water Supply Authority (NJWSA) for the purchase of untreated water through November 30, 2023, which provides for an average purchase of 27.0 million gallons a day (mgd). Pricing is set annually by the NJWSA through a public rate making process. The agreement has provisions for additional pricing in the event Middlesex overdrafts or exceeds certain monthly and annual thresholds.

Middlesex also has an agreement with a non-affiliated regulated water utility for the purchase of treated water. This agreement, which expires February 27, 2021, provides for the minimum purchase of 3.0 mgd of treated water with provisions for additional purchases.

Tidewater contracts with the City of Dover, Delaware to purchase treated water of 15.0 million gallons annually.

Contract Operations - USA-PA operates the City of Perth Amboy, New Jersey’s (Perth Amboy) water and wastewater collection systems under a 20-year agreement, which expires in 2018. In connection with the agreement with Perth Amboy, USA-PA entered into a 20-year subcontract with a wastewater operating company for the operation and maintenance of the Perth Amboy wastewater collection system. The subcontract provides for the sharing of certain fixed and variable fees and operating expenses and its term is concurrent with USA-PA’s contract with Perth Amboy.

Guarantees - As part of an agreement with the County of Monmouth, New Jersey (County), Middlesex serves as guarantor of the performance of Applied Water Management, Inc. (AWM), an unaffiliated wastewater treatment contractor, to operate a County-owned leachate pretreatment facility at the Monmouth County Reclamation Center in Tinton Falls, New Jersey. The performance guaranty is effective through 2028 unless another guarantor, acceptable to the County, replaces Middlesex before such date. Under agreements with AWM and Natural Systems Utilities, LLC (NSU), the parent company of AWM, Middlesex earns a fee for providing the performance guaranty. In addition, Middlesex may provide operational support to the facility, as needed, and AWM and NSU, serving as guarantor to Middlesex with respect to the performance of AWM, agree to indemnify Middlesex against any claims that may arise under the Middlesex guaranty to the County.

Index

If requested to perform under the guaranty to the County and, if AWM and NSU, as guarantor to Middlesex, do not fulfill their obligations to indemnify Middlesex against any claims that may arise under the Middlesex guaranty to the County, Middlesex would be required to fulfill the remaining operational commitment of AWM. As of December 31, 2016 and December 31, 2015, the liability recognized in Other Non-Current Liabilities on the balance sheet for the guaranty is approximately $0.1 million and $0.2 million, respectively.

Construction –The Company has projected to spend up to $60.2 million in 2017, $88.9 million in 2018 and $73.8 million in 2019 on its construction program. The actual amount and timing of capital expenditures is dependent on the need for replacement of existing infrastructure, customer growth, residential new home construction and sales, project scheduling and continued refinement of project scope and costs. There is no assurance that projected customer growth and residential new home construction and sales will occur.

Litigation – The Company is a defendant in lawsuits in the normal course of business. We believe the resolution of pending claims and legal proceedings will not have a material adverse effect on the Company’s consolidated financial statements.

Change in Control Agreements – The Company has Change in Control Agreements with certain of its officers that provide compensation and benefits in the event of termination of employment in connection with a change in control of the Company.

Note 6 - Capitalization

All the transactions discussed below related to the issuance of securities were approved by either the NJBPU or DEPSC, except where otherwise noted.

Common Stock

The Company periodically issues shares of its common stock in connection with its Middlesex Water Company Investment Plan (the Investment Plan), a direct share purchase and sale and dividend reinvestment plan for Middlesex common stock. In July 2015, the Company registered an additional 700,000 common shares for potential issuance under the Investment Plan with the United States Securities and Exchange Commission,

Index

increasing the number of NJBPU-authorized shares to 3.0 million. The cumulative number of shares issued under the Investment Plan at December 31, 2016 is 2.3 million. For the years ended December 31, 2016, 2015 and 2014, the Company raised approximately $1.5 million, respectively, through the issuance of shares under the Investment Plan.

The Company issues shares under a restricted stock plan for certain management employees, which is described in Note 7 – Employee Benefit Plans.

The Company maintains a stock plan for its outside directors (the Outside Director Stock Compensation Plan). For the years ended December 31, 2016, 2015 and 2014, 3,976, 4,795 and 5,082 shares, respectively, of Middlesex common stock were granted and issued to the Company’s outside directors under the Outside Director Stock Compensation Plan and 68,144 shares remain available for future awards. The maximum number of shares authorized for grant under the Outside Director Stock Compensation Plan is 100,000.

In the event dividends on the preferred stock are in arrears, no dividends may be declared or paid on the common stock of the Company.

Preferred Stock

At December 31, 2016 and 2015, there were 0.1 million shares of preferred stock authorized and less than 0.1 million shares of preferred stock outstanding. There were no preferred stock dividends in arrears.

The Company may not pay any dividends on its common stock unless full cumulative dividends to the preceding dividend date for all outstanding shares of preferred stock have been paid or set aside for payment. If four or more quarterly dividends are in arrears, the preferred shareholders, as a class, are entitled to elect two members to the Board of Directors in addition to Directors elected by holders of the common stock. In addition, if Middlesex were to liquidate, holders of preferred stock would be paid back the stated value of their preferred shares before any distributions could be made to common stockholders.

The conversion feature of the no par $7.00 Series Cumulative and Convertible Preferred Stock allows the security holders to exchange one convertible preferred share for twelve shares of the Company's common stock. In addition, the Company may redeem up to 10% of the outstanding convertible stock in any calendar year at a price equal to the fair value of twelve shares of the Company's common stock for each share of convertible stock redeemed. In 2014, 4,293 shares (approximately $0.5 million) of the Company’s no par $7.00 Series Cumulative and Convertible Preferred Stock were converted into 51,516 shares of common stock.

The conversion feature of the no par $8.00 Series Cumulative and Convertible Preferred Stock allows the security holders to exchange one convertible preferred share for 13.714 shares of the Company's common stock. The preferred shares are convertible into common stock at the election of the security holder or Middlesex.

Long-term Debt

Subject to regulatory approval, the Company periodically issues long-term debt to fund its investments in utility plant and other assets. To the extent possible, the Company finances qualifying capital projects under State Revolving Fund (SRF) loan programs in New Jersey and Delaware. These government programs provide financing at interest rates that are typically below rates available in the broader financial markets. A portion of the borrowings under the New Jersey SRF is interest-free. Under the New Jersey SRF program, borrowers first enter into a construction loan with the New Jersey Environmental Infrastructure Trust (NJEIT) at a below market interest rate. The current interest rate on construction loan borrowings is zero percent (0%). When construction on the qualifying project is substantially complete, the NJEIT will coordinate the conversion of the construction loan into a long-term securitized loan with a portion of the principal balance having a stated interest rate of zero percent (0%) and a portion of the principal balance at a market interest rate at the time of closing using the credit rating of the State of New Jersey. The current term of the long-term loans offered through the NJEIT is up to

Index

thirty years. The current portion of the principal balance having a stated interest rate of zero percent (0%) is 75% with the remaining portion of 25% having a market based interest rate. The NJEIT generally schedules its long-term debt financings in May and November.

In March 2016, the NJBPU approved Middlesex’s request to borrow up to $16.0 million under the New Jersey SRF program to fund the 2016 RENEW Program, which is an ongoing initiative to eliminate all unlined water distribution mains in the Middlesex system. Middlesex closed on an $11.8 million zero percent (0%) SRF construction loan on June 28, 2016. Through December 31, 2016, Middlesex has drawn down $7.5 million and expects to draw down the remaining proceeds during the first quarter of 2017. The NJEIT notified the Company that it has scheduled this project to be included in the May 2017 long-term loan financing.

In 2015, Tidewater completed the drawdown of a $15.0 million long-term debt transaction. The interest rate on $11.0 million of the loan is 4.45%. $4.0 million of the loan was initially set up as a market-based variable interest rate transaction, but which was switched to a fixed rate of 4.47% in January 2017. The proceeds were used to pay down short-term debt and for other general corporate purposes. The final maturity date of all borrowings under this loan agreement is April 2040.

Bond Series QQ, RR and SS are term bonds with single maturity dates subsequent to 2020. Principal repayments for all series of the Company’s long-term debt except for Bond Series X, Y, Z and AA extend beyond 2020. The aggregate annual principal repayment obligations for all long-term debt over the next five years are shown below:

Year		(Millions of Dollars) Annual Maturities
	2017	$	6.2
	2018	$	6.6
	2019	$	6.6
	2020	$	6.4
	2021	$	6.4

The weighted average interest rate on all long-term debt at December 31, 2016 and 2015 was 3.88% and 3.87%, respectively. Except for the Amortizing Secured Notes ($42.5 million), all of the Company’s outstanding long-term debt has been issued through the New Jersey Economic Development Authority ($55.4 million), the NJEIT program ($34.8 million) and the Delaware SRF program ($9.7 million).

In both 2016 and 2015, the NJEIT de-obligated principal payments of $0.5 million on several series of SRF long-term debt.

Earnings Per Share

The following table presents the calculation of basic and diluted earnings per share (EPS) for the three years ended December 31, 2016. Basic EPS is computed on the basis of the weighted average number of shares outstanding. Diluted EPS assumes the conversion of both the Convertible Preferred Stock $7.00 Series and $8.00 Series.

Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments for which it is practicable to estimate that value. The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and notes payable approximate their respective fair values due to the short-term maturities of these instruments. The fair value of First Mortgage and State Revolving Fund Bonds (collectively, the Bonds) issued by Middlesex is based on quoted market prices for similar issues. Under the fair value hierarchy, the fair value of cash and cash equivalents is classified as a Level 1 measurement and the fair value of notes payable and the Bonds in the table below are classified as Level 2 measurements. The carrying amount and fair value of the Bonds were as follows:

	(Thousands of Dollars)
	At December 31,
	2016				2015
	Carrying		Fair		Carrying		Fair
	Amount		Value		Amount		Value
Bonds	$	82,786	$	84,821	$	85,600	$	88,431

For other long-term debt issuances for which there is no quoted market price and there is not an active trading market, it was not practicable to estimate their fair value. For details, including carrying value, interest rate and due date on these series of long-term debt, please refer to those series of long-term debt described as “Amortizing Secured Note”, “State Revolving Trust Note” and “Construction Loans” on the Condensed Consolidated Statements of Capital Stock and Long-Term Debt). The carrying amount of these instruments was $59.7 million and $54.7 million at December 31, 2016 and December 31, 2015, respectively. Customer advances for construction have carrying amounts of $20.8 million and $20.5 million at December 31, 2016 and December 31, 2015, respectively. Their relative fair values cannot be accurately estimated since future refund payments depend on several variables, including new customer connections, customer consumption levels and future rate increases.

Note 7 - Employee Benefit Plans

Pension Benefits

The Company’s Pension Plan covers all active employees hired prior to April 1, 2007. Employees hired after March 31, 2007 are not eligible to participate in this plan, but can participate in a defined contribution profit sharing plan that provides an annual contribution at the discretion of the Company, based upon a percentage of the participants’ annual paid compensation. In order to be eligible for contribution, the eligible employee must be

Index

employed by the Company on December 31^st of the year to which the contribution relates. The Company maintains an unfunded supplemental plan for its executive officers. The Accumulated Benefit Obligation for the Company’s Pension Plan at December 31, 2016 and 2015 was $66.8 million and $62.3 million, respectively.

Other Benefits

The Company’s Other Benefits Plan covers substantially all of its current retired employees. Employees hired after March 31, 2007 are not eligible to participate in this plan. Coverage includes healthcare and life insurance. Accrued retirement benefit costs are recorded each year.

Regulatory Treatment of Over/Underfunded Retirement Obligations

Because the Company is subject to regulation in the states in which it operates, it is required to maintain its accounts in accordance with the regulatory authority’s rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance of ASC 980, Regulated Operations. Based on prior regulatory practice, and in accordance with the guidance in ASC 980, Regulated Operations, the Company records underfunded Pension Plan and Other Benefits Plan obligation costs, which otherwise would be recognized in Other Comprehensive Income under ASC 715, Compensation – Retirement Benefits, as a Regulatory Asset, and expects to recover those costs in rates charged to customers.

The Company uses a December 31 measurement date for all of its employee benefit plans. The tables below set forth information relating to the Company’s Pension Plan and Other Benefits Plan for 2016 and 2015.

Two outside investment firms each manage a portion of the Pension Plan asset portfolio. One of those investment firms also manages the Other Benefits Plan asset portfolio. Quarterly meetings are held between the Company’s Pension Committee of the Board of Directors and the investment managers to review their performance and asset allocation. If the actual asset allocation is outside the targeted range, the Pension Committee reviews current market conditions and advice provided by the investment managers to determine the appropriateness of rebalancing the portfolio.

Index

The objective of the Company is to maximize the long-term return on retirement plan assets, relative to a reasonable level of risk, maintain a diversified investment portfolio and maintain compliance with the Employee Retirement Income Security Act of 1974. The expected long-term rate of return is based on the various asset categories in which plan assets are invested and the current expectations and historical performance for these categories.

Equity securities include Middlesex common stock in the amounts of $0.8 million (1.4% of total Pension Plan assets) and $1.0 million (2.0 % of total Pension Plan assets) as of December 31, 2016 and 2015, respectively.

Fair Value Measurements

Accounting guidance provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:

Level 1 – Inputs to the valuation methodology are unadjusted quoted market prices for identical assets or liabilities in accessible active markets.

Level 2 – Inputs to the valuation methodology that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. If the asset or liability has a specified contractual term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Certain investments in cash and cash equivalents, equity securities, and commodities are valued based on quoted market prices in active markets and are classified as Level 1 investments. Certain investments in cash and cash equivalents, equity securities and fixed income securities are valued using prices received from pricing vendors that utilize observable inputs and are therefore classified as Level 2 investments.

Benefit Plans Contributions

For the Pension Plan, Middlesex made total cash contributions of $3.6 million in 2016 and expects to make approximately $3.3 million of cash contributions in 2017.

For the Other Benefits Plan, Middlesex made total cash contributions of $1.6 million in 2016 and expects to make approximately $1.6 million of cash contributions in 2017.

401(k) Plan

The Company maintains a 401(k) defined contribution plan, which covers substantially all employees with more than 1,000 hours of service. Under the terms of the Plan, the Company matches 100% of a participant’s contributions, which do not exceed 1% of a participant’s compensation, plus 50% of a participant’s contributions exceeding 1%, but not more than 6%. The Company’s matching contribution was $0.6 million for each of the years ended December 31, 2016, 2015 and 2014.

For those employees hired after March 31, 2007, and still actively employed on December 31, 2016, the Company approved, and will fund, a discretionary contribution of $0.4 million which was based on 5.0% of eligible 2016 compensation. For the years ended December 31, 2015 and 2014, the Company made discretionary contributions of $0.4 million and $0.3 million, respectively, for qualifying employees.

Stock-Based Compensation

The Company has a stock compensation plan for certain management employees (the 2008 Restricted Stock Plan). The Company maintains an escrow account for 0.1 million shares of the Company's common stock for the 2008 Restricted Stock Plan. Shares issued in connection with the 2008 Restricted Stock Plan are subject to forfeiture by the employee in the event of termination of employment within five years of the award other than as a result of normal retirement, death, disability or change in control. The maximum number of shares authorized for grant under the 2008 Restricted Stock Plan is 0.3 million shares, for which 0.1 million remain as unissued shares.

Index

The Company recognizes compensation expense at fair value for the 2008 Restricted Stock Plan awards in accordance with ASC 718, Compensation – Stock Compensation. Compensation expense is determined by the market value of the stock on the date of the award and is being amortized over a five-year period.

Note 8 – Business Segment Data

The Company has identified two reportable segments. One is the regulated business of collecting, treating and distributing water on a retail and wholesale basis to residential, commercial, industrial and fire protection customers in parts of New Jersey, Delaware and Pennsylvania. This segment also includes regulated wastewater systems in New Jersey and Delaware. The Company is subject to regulations as to its rates, services and other matters by the states of New Jersey, Delaware and Pennsylvania with respect to utility service within these states. The other segment is primarily comprised of non-regulated contract services for the operation and maintenance of municipal and private water and wastewater systems in New Jersey and Delaware.

Inter-segment transactions relating to operational costs are treated as pass-through expenses. Finance charges on inter-segment loan activities are based on interest rates that are below what would normally be charged by a third party lender.

CONTROLS AND PROCEDURES

(1) Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in Company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in Company reports filed under the Exchange Act is accumulated and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding disclosure.

As required by Rule 13a-15 under the Exchange Act, an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures was conducted by the Company’s Chief Executive Officer along with the Company’s Chief Financial Officer for the quarter ended December 31, 2016. Based upon that evaluation the Company’s Chief Executive Officer and the Company’s Chief Financial Officer concluded:

(a) Disclosure controls and procedures were effective as of the end of the period covered by this report.

(b) No changes in internal control over financial reporting occurred during our most recent fiscal quarter that has materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

Accordingly, management believes the consolidated financial statements included in this report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented.

Index

(2) Management’s Report on Internal Control Over Financial Reporting

The management of Middlesex Water Company (Middlesex or the Company) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13A-15(f) and 15d-15(f). Middlesex’s internal control system was designed to provide reasonable assurance to the Company’s management and Board of Directors of adequate preparation and fair presentation of the published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to the adequacy of financial statement preparation and presentation. Middlesex’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 framework). Based on our assessment, we believe that as of December 31, 2016, the Company’s internal control over financial reporting is operating as designed and is effective based on those criteria.

Middlesex’s independent registered public accounting firm has audited the effectiveness of our internal control over financial reporting as of December 31, 2016 as stated in their report which is included herein.

(3) Report of Independent Registered Public Accounting Firm

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Middlesex Water Company

We have audited Middlesex Water Company’s (the “Company”) internal control over financial reporting as of December 31, 2016 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Middlesex Water Company's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

An entity’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. An entity’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and directors of the entity; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the entity’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Middlesex Water Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets and consolidated statements of capital stock and long-term debt and the related consolidated statements of income, common stockholders’ equity, and cash flows of Middlesex Water Company and our report dated March 3, 2017 expressed an unqualified opinion.
