If, based on the qualitative factors, an entity determines that the fair value of the reporting unit is greater than its carrying amount, then the entity would not be required to perform the two-step quantitative impairment test for that reporting unit. However, if the qualitative assessment indicates that it is not more-likely-than-not that the reporting unit’s fair value exceeds its carrying value, then the quantitative assessment must be performed. An entity is permitted to perform the qualitative assessment on none, some or all of its reporting units and may also elect to bypass the qualitative assessment and begin with the quantitative assessment of goodwill impairment.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The interim consolidated financial statements reflect all adjustments which in the opinion of management are necessary for a fair statement of results of operations, comprehensive income, financial condition, cash flows and stockholders' equity for the periods presented. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. The interim consolidated financial statements have been compiled without audit. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s 2011 Annual Report on Form 10-K.

The year-end balance sheet data was derived from the audited financial statements as of December 31, 2011, but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Earnings Per Share

The Company’s unvested restricted common stock and unvested restricted stock units that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in the earnings allocation in computing earnings per share using the two-class method. Basic earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding. Diluted earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding after giving effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the dilutive effect of outstanding stock options and performance share units granted under the Company’s Amended and Restated Employee Long-Term Incentive Plan and its Amended and Restated Non-Employee Director Long-Term Incentive Plan. Earnings allocable to participating securities include the portion of dividends declared as well as the portion of undistributed earnings during the period allocable to participating securities.

Adoption of New Accounting Standards

On January 1, 2012, the Company adopted an amendment issued by the Financial Accounting Standards Board ("FASB") to the accounting standards related to fair value measurements and disclosure requirements. This standard provides certain amendments to the existing guidance on the use and application of fair value measurements and maintains a definition of fair value that is based on the notion of exit price. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

On January 1, 2012, the Company adopted amendments issued by the FASB to the accounting standards related to the presentation of comprehensive income.
