The statements are unaudited but include all adjustments, consisting only of recurring items, except as noted, that the Company considers necessary for a fair presentation of the information set forth herein. The results of operations for the six months ended June 30, 2012 are not necessarily indicative of the results to be expected for the entire year.

ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The Company adopted this guidance on January 1, 2012, and its adoption did not impact the consolidated financial position, results of operations or cash flows of the Company. In June 2011, FASB issued ASU 2011-05 “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 allows an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, FASB issued ASU 2011-12 “Comprehensive Income (Topic 220); Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”). ASU 2011-12 deferred certain aspects of ASU 2011-05. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 and the deferrals in ASU 2011-12 did not impact the consolidated financial position, results of operations or cash flows of the Company.
