Item 3. Source and Amount of Funds or Other Consideration

     On December 21, 2004, Pampa acquired 6,000,000 Series A Shares on the
Chilean Stock Exchange for an aggregate purchase price of Ch$24,006,000,000.
Yara loaned Pampa the funds necessary to complete the acquisition. In order to
secure the loan from Yara, Pampa issued notes to Yara in the amount of
US$43,000,000 (the "Notes"). On January 10, 2005, Pampa repaid Yara the full
amount due under the Notes with the proceeds of a loan from Banco BCI, which
matures on May 30, 2012 and accrues interest at an annual rate of 6.56%.



                                                                             14


     On January 14, 2005, SQYA acquired 6,145,092 Series A Shares on the
Chilean Stock Exchange for an aggregate purchase price of Ch$24,592,658,184.
Yara and Banco BCI loaned SQYA the funds necessary to complete the
acquisition. In order to secure the loans from Yara and Banco BCI, SQYA issued
notes to Yara and Banco BCI in the amounts of US$30,000,000 and US$20,000,000,
respectively. The notes issued to Yara mature on May 30, 2015 and accrue
interest at an annual rate of 6.65%. The notes issued to Banco BCI mature on
May 30, 2011 and accrue interest at an annual rate of 6.40%.

     Pampa originally acquired ownership of 53,557,332 Series A Shares prior
to SQM's registration with the Securities Exchange Commission with funds
received from bank loans and capital contributions of its affiliates.

     On June 4, 2006, Pampa initiated a tender offer in Chile for Series B
Shares. The tender offer was consummated on July 3, 2006, and in connection
with the tender offer Pampa acquired 6,207,539 Series B shares for an
aggregate purchase price of Ch$35,072,595,350. The source of funds for the
acquisition of shares include (i) affiliate contributions in the amount of
Ch$13,602,595,350; (ii) a loan from Banco Santander Santiago in the amount of
US$30,000,000, which matures in 180 days from June 4, 2006 (this loan is in
the process of being refinanced with a new loan from Banco Santander Santiago,
which is expected to mature in June 2012); (iii) a loan from Banco BCI in the
amount of US$6,500,000, which matures in June 2012 and (iv) a loan from Banco
Corpbanca in the amount of US$6,500,000, which matures in June 2012. The
average annual interest rate on these three loans is 7.19%.

Item 4. Purpose of Transaction

     Pampa and SQYA undertook the purchase of additional shares of Series A
Shares in order to increase their interest in SQM. The interests of Pampa,
SQYA and the Reporting Persons in SQM were acquired solely for the purpose of
investment.

     Pampa purchased the Series B Shares in order to increase Mr. Ponce's
indirect combined ownership in SQM to over 25% for investment purposes so that
he would be deemed, solely for purposes of Chilean law, as a "controlling
shareholder" under Articles No. 97 and No. 99 of the Chilean Securities Market
Law. The acquisition by Pampa of the Series B Shares, however, did not
materially affect the Reporting Persons' control rights over SQM since the
Series B Shares have limited voting rights (holders of Series B Shares elect
one of eight members of the Board of Directors (the "Series B Director") and
vote together with the Series A Shares on other matters); the Reporting
Persons' ownership of 5.16% of the Series B Shares does not allow them to
materially influence the election of the Series B Director and their increased
ownership, on a combined basis, of Series A and Series B Shares from 24.97% to
27.33% does not materially increase their voting power with respect to other
matters. Although being deemed as a "controlling shareholder" for purposes of
Chilean law does not provide additional control rights, it does result, under
Chilean corporate law, in the "controlling shareholder" not being required to
extend a mandatory public tender offer upon subsequent purchases of securities
of the Company.

     Each of the Reporting Persons intends to review its investment in SQM on
a regular basis and, as a result thereof, may at any time or from time to time
determine, either alone or as part of a group, (a) to acquire additional
securities of SQM, through open market purchases, privately negotiated
transactions or otherwise, (b) to dispose of all or a portion of the
securities of SQM owned by it in the open market, in privately negotiated
transactions, in one or more registered public offerings or otherwise, or (c)
to take any other available course of action, which could involve one or more
of the types of transactions or have one or more of the results described in
the next paragraph of this Item 4. Notwithstanding anything contained herein,
each of the Reporting Persons specifically reserves the right to change its
intention with respect to any or all of such matters. In reaching any decision
as to its course of action (as well as to the specific elements thereof), each
of the Reporting Persons currently expects that it would take into
consideration a variety of factors, including, but not limited to, the
following: SQM's business and prospects; other developments concerning SQM and
its businesses generally; other business opportunities available to the
Reporting Persons; changes in law and government regulations;



                                                                             15


general economic conditions; and financial and stock market conditions,
including the market price of the Series A and Series B Shares.

     Except as set forth in this Item 4, the Reporting Persons have no present
plans or proposals that relate to, or that would result in, any of the actions
specified in clauses (a) through (j) of Schedule 13D of the Exchange Act.
