Credit loss estimates	Credit loss estimates are derived by comparing the estimated fair value of the securities, which are based on a number of factors, including estimated probabilities of default, with the value that would have been derived if the probability of default for the same securities were zero percent. The difference between the recorded fair value and the estimated fair value assuming a zero probability of default is considered the portion of total decline in fair value attributable to credit losses.

Recently issued accounting standards, not yet adopted as of December 31, 2012	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”).  The objective of ASU 2013-02 is to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments require disclosure of information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, disclosure is required, either on the face of the statement where net income is presented or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The new requirements will take effect for public companies in interim and annual reporting periods beginning after December 15, 2012. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.
Recently adopted accounting pronoucements	In July 2012, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2012-02 Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”). ASU 2012-02 permits an entity to first assess qualitative factors to determine whether it is "more likely than not" (or a likelihood greater than 50%) that an indefinite-lived intangible asset is impaired before performing quantitative impairment testing. ASU 2012-02 is effective for fiscal years beginning after September 15, 2012, with early adoption permitted. The Company adopted ASU 2012-02 in connection with its 2012 indefinite-lived intangible asset impairment assessment. See Note 5 – Goodwill and Other Intangible Assets. In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“ASU 2011-04”). The objective of ASU 2011-04 is to converge guidance of the FASB and the International Accounting Standards Board on fair value measurement and disclosure. This update changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and disclosing information about fair value measurements; clarifies the FASB’s intent about the application of existing fair value measurement requirements; and changes particular principles or requirements for measuring fair value or for disclosing information about fair value measurements. ASU 2011-04, which the Company adopted as of January 1, 2012, was effective prospectively for interim and annual periods beginning after December 15, 2011. The wording of fair value disclosures in Note 6 - Fair Value of Financial Instruments corresponds to the new requirements. In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”). The objective of ASU 2011-05 is to improve the comparability, consistency and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income. ASU 2011-05 provides the option to present the total of comprehensive income, (equal to the components of net income and the components of other comprehensive income) either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of shareholders' equity as shown in the prior years. In December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05 (“ASU 2011-12”), which defers the provisions in ASU 2011-05 relating to the presentation of reclassification adjustments. ASU 2011-12 reinstates the requirements for the presentation of reclassifications out of accumulated other comprehensive income that were in place before ASU 2011-05. The remaining provisions of ASU 2011-05 are effective retrospectively for annual periods, and interim periods within those years, beginning after December 15, 2011. ASU 2011-12, which the Company adopted as of January 1, 2012, is effective for reporting periods beginning after December 15, 2011. See the consolidated statements of comprehensive income for related disclosures.
