Summary of Significant Accounting Policies  
Use of Estimates in the Preparation of Financial Statements
Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes.  Actual results may differ from those estimates and such differences could be material to the financial statements.

Realized gains and losses are recorded in noninterest income using the specific identification method.
Offsetting Assets and Liabilities
Offsetting Assets and Liabilities

In December 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2011-11, “Disclosures About Offsetting Assets and Liabilities.” This project began as an attempt to converge the offsetting requirements under U.S. GAAP and International Financial Reporting Standards ("IFRS"). However, as the FASB and International Accounting Standards Board were not able to reach a converged solution with regards to offsetting requirements, they each developed convergent disclosure requirements to assist in reconciling differences in the offsetting requirements under U.S. GAAP and IFRS. The new disclosure requirements mandate that entities disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position as well as instruments and transactions subject to an agreement similar to a master netting arrangement. ASU No. 2011-11 also requires disclosure of collateral received and posted in connection with master netting agreements or similar arrangements. In January 2013, the FASB issued ASU No. 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities." The provisions of ASU No. 2013-01 limits the scope of the new balance sheet offsetting disclosures to the following financial instruments, to the extent they are offset in the financial statements or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in the statement of financial position: (1) derivative financial instruments; (2) repurchase agreements and reverse repurchase agreements; and (3) securities borrowing and securities lending transactions. The Company adopted the provisions of ASU No. 2011-11 and ASU No. 2013-01 effective January 1, 2013. As the provisions of ASU No. 2011-11 and ASU No. 2013-01 only impacted the disclosure requirements related to the offsetting of assets and liabilities and information about instruments and transactions eligible for offset in the statement of financial position, the adoption had no impact on the Company's consolidated statements of income and condition.
Reclassifications Out of Accumulated Other Comprehensive Income
Reclassifications Out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued ASU No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," to improve the transparency of reporting these reclassifications. ASU No. 2013-02 does not amend any existing requirements for reporting net income or other comprehensive income in the financial statements. ASU No. 2013-02 requires an entity to disaggregate the total change of each component of other comprehensive income (e.g., unrealized gains or losses on available-for-sale investment securities) and separately present reclassification adjustments and current period other comprehensive income. The provisions of ASU No. 2013-02 also requires that entities present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source (e.g., unrealized gains or losses on available-for-sale investment securities) and the income statement line item affected by the reclassification (e.g., realized gains (losses) on sales of investment securities). If a component is not required to be reclassified to net income in its entirety (e.g., amortization of defined benefit plan items), entities would instead cross reference to the related note to the financial statements for additional information (e.g., pension footnote). The Company adopted the provisions of ASU No. 2013-02 effective January 1, 2013. As the Company provided these required disclosures in the notes to the Consolidated Financial Statements, the adoption of ASU No. 2013-02 had no impact on the Company's consolidated statements of income and condition.
