Recent Accounting Pronouncements and Updates to Significant Accounting Policies	Recent Accounting Pronouncements and Updates to Significant Accounting Policies Recent Accounting Pronouncements Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements — In May 2011, the Financial Accounting Standards Board (FASB) issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820)—Fair Value Measurement, to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. ASU 2011-04 was effective for the first quarter of 2012 and was applied prospectively. Adoption of this standard resulted in additional disclosures as presented in Note 13 but did not have any impact on the Company’s results of operations. Presentation of Comprehensive Income — In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220)—Presentation of Comprehensive Income, to require an entity to present the total of comprehensive income, 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. ASU 2011-05 is effective for the first quarter of 2012 and should be applied retrospectively. Adoption of this standard resulted in the presentation of a new statement of comprehensive income separate from the statement of shareholders’ equity but did not have any impact on the Company’s results of operations. In December 2011, the 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, to allow time to redeliberate whether to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. Adoption of this ASU did not have any impact on the Company’s consolidated financial statements or results of operations. Intangibles - Goodwill & Other — In September 2011, the FASB issued ASU 2011-08, Intangibles - Goodwill and Other (Topic 350) —Testing Goodwill for Impairment, which affect all entities that have goodwill reported in their financial statements. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The more likely than not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the totality of events or circumstances, an entity determines that it is more likely than not that the fair value of a reporting unit is more than its carrying amount, then performing the two-step impairment test is not required. Under the amendments in this update, an entity is no longer permitted to carry forward its detailed calculation of a reporting unit's fair value from a prior year as previously permitted under ASC Topic 350. This guidance was adopted in conjunction with the performance of the Company's annual goodwill impairment test performed during the second quarter of 2012. Adoption of this standard did not have any impact on the Company's consolidated financial statements or results of operations. Updates to Significant Accounting Policies Goodwill and Intangible Assets - Goodwill, core deposit premiums and other intangible assets are included in other assets in the consolidated balance sheets. Goodwill is not amortized and is evaluated for potential impairment on an annual basis or when events or circumstances indicate a potential impairment, at the reporting unit level. Reporting units are first evaluated qualitatively to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is believed that it is more likely than not that a reporting unit's fair value is less than its carrying value, the Company will estimate the reporting unit's fair market value to determine whether carrying value exceeds fair market value. If carrying value exceeds fair market value, goodwill is written down. The Company may use judgment in assessing goodwill and intangible assets for impairment. Estimates of fair value are based on projections of revenues, operating costs and cash flows of each reporting unit considering historical and anticipated future results, general economic and market conditions as well as the impact of planned business or operational strategies. The valuations employ a combination of present value techniques to measure fair value and consideration of market factors. Additionally, judgment is used in determining the useful lives of finite-lived intangible assets. Changes in judgments and projections could result in a significantly different estimate of the fair value of the reporting units and could result in an impairment of goodwill. Core deposit premiums are amortized over the estimated life of the acquired deposits using the straight-line method. Core deposit premiums are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Other identifiable intangible assets were recognized through business combinations. These intangible assets are amortized over their estimated life. No residual value was assigned to any of these intangible assets.

Updates to Significant Accounting Policies

Goodwill and Intangible Assets - Goodwill, core deposit premiums and other intangible assets are included in other assets in the consolidated balance sheets.

Goodwill is not amortized and is evaluated for potential impairment on an annual basis or when events or circumstances indicate a potential impairment, at the reporting unit level. Reporting units are first evaluated qualitatively to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is believed that it is more likely than not that a reporting unit's fair value is less than its carrying value, the Company will estimate the reporting unit's fair market value to determine whether carrying value exceeds fair market value. If carrying value exceeds fair market value, goodwill is written down.

The Company may use judgment in assessing goodwill and intangible assets for impairment. Estimates of fair value are based on projections of revenues, operating costs and cash flows of each reporting unit considering historical and anticipated future results, general economic and market conditions as well as the impact of planned business or operational strategies. The valuations employ a combination of present value techniques to measure fair value and consideration of market factors. Additionally, judgment is used in determining the useful lives of finite-lived intangible assets. Changes in judgments and projections could result in a significantly different estimate of the fair value of the reporting units and could result in an impairment of goodwill.

Core deposit premiums are amortized over the estimated life of the acquired deposits using the straight-line method. Core deposit premiums are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Other identifiable intangible assets were recognized through business combinations. These intangible assets are amortized over their estimated life.
