Dear Directors:
We are providing this letter to you for inclusion as an exhibit to your Form 10-Q filing pursuant
to Item 601 of Regulation S-K.
We have been provided a copy of the Companys Quarterly Report on Form 10-Q for the period ended
December 31, 2007. Note 1 therein describes a change in accounting principle related to changing
the Companys annual goodwill impairment test date in accordance with Statement of Financial
Accounting Standards No. 142, Goodwill and Other Intangible Assets (FAS 142) from October 31 to
the last day in February. It should be understood that the preferability of one acceptable method
of accounting over another for the annual goodwill impairment test date in accordance with FAS 142
has not been addressed in any authoritative accounting literature, and in expressing our
concurrence below we have relied on managements determination that this change in accounting
principle is preferable. Based on our reading of managements stated reasons and justification for
this change in accounting principle in the Form 10-Q, and our discussions with management as to
their judgment about the relevant business planning factors relating to the change, we concur with
management that such change represents, in the Companys circumstances, the adoption of a
preferable accounting principle in conformity with Statement of Financial Accounting Standards No.
154, Accounting Changes and Error Corrections.
We have not audited any financial statements of the Company as of any date or for any period
subsequent to December 31, 2006. Accordingly, our comments are subject to change upon completion
of an audit of the financial statements covering the period of the accounting change.
Very truly yours,
PricewaterhouseCoopers LLP
