In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2011 are not necessarily an indication of the results that may be expected for the year ending December 31, 2011.

New Accounting Standards

In April 2011, FASB issued ASU No. 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring. It provided additional guidance to assist creditors in determining whether a restructuring of a receivable meets the criteria to be considered a troubled debt restructuring. The amendments in this ASU are effective for the first interim or annual period beginning on or after June 15, 2011, and are to be applied retrospectively to the beginning of the annual period of adoption. The adoption of this ASU did not have a material impact on our consolidated financial position or results of operations.

In September 2011, FASB issued ASU No. 2011-08, Testing for Goodwill Impairment. It allows companies the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Companies would then only proceed to the existing two step impairment test if, after assessing the totality of the events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount. The ASU is effective for annual and interim goodwill tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. We intend to early adopt this ASU and apply to our annual goodwill assessment performed on October 1, 2011.

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, “Statement of Comprehensive Income” (“ASU 2011-05”), which requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 will only impact the company’s financial presentation as the company currently presents items of other comprehensive income in the statement of changes in equity. ASU 2011-05 will be effective for our fiscal year beginning January 1, 2012.
