The registrant requires additional time to complete certain aspects of its fiscal 2017 Form 10-K. The registrant continues to dedicate significant resources to the audit of the financial statements, internal control testing and reporting, and the fiscal 2017 Form 10-K. Currently, the registrant expects to timely file its fiscal 2017 Form 10-K within the extension period granted hereby.

The registrant expects to report net income of $5.8 million for fiscal 2017 compared with net income of $12.2 million for fiscal 2016. The registrant disseminated a press release dated December 1, 2017 describing its results of operations for the quarter and twelve months ended September 30, 2017. A copy of that press release was filed by the registrant as an exhibit to the registrant's Current Report on Form 8-K filed with the Securities and Exchange Commission on December 1, 2017. The registrant does not expect that the results presented in its Annual Report on Form 10-K for the fiscal year ended September 30, 2017 will differ in any material respect from the results described in its December 1, 2017 press release.
