ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
None.
ITEM 9A. CONTROLS AND PROCEDURES
The company maintains a system of disclosure controls and procedures to give reasonable assurance that information required to be disclosed in the
company's reports filed or submitted under the Securities Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized and reported within the
time periods specified in the rules and forms of the SEC. These controls and procedures also give reasonable assurance that information required to be
disclosed in such reports is accumulated and communicated to management to allow timely decisions regarding required disclosures.
As of December 31, 2011, the company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), together with management, conducted an
evaluation of the effectiveness of the company's disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on
that evaluation, the CEO and CFO concluded that these disclosure controls and procedures are effective.
There has been no change in the company's internal control over financial reporting that occurred during the fourth quarter of 2011 that has materially
affected, or is reasonably likely to materially affect, the company's internal control over financial reporting. The company has completed its evaluation of its
internal controls and has concluded that the company's system of internal controls over financial reporting was effective as of December 31, 2011 (see
page F-2).
ITEM 9B. OTHER INFORMATION
