Accounting Policies [Abstract]
Newly Adopted Accounting Pronouncements	*Newly Adopted Accounting Pronouncements* ASU 2013-11 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). ASU 2013-11 requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. However, if a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments are not expected to have a material impact on the Company’s results of operations, financial position or disclosures. ASU 2013-02 – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). ASU 2013-02 requires an entity to provide information about the amounts reclassified from accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, 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 United States generally accepted accounting principles to be reclassified to net income in its entirety in the same reporting period. For all other amounts, an entity is required to cross-reference to other disclosures that provide additional details about these amounts. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. It did not have a material effect on the Company’s results of operations, financial position or disclosures. ASU 2012-06 – Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution (“ASU 2012-06”). When an entity recognizes an indemnification asset and subsequently a change in the cash flows expected to be collected on the indemnification asset occurs as a result of a change in the cash flows expected to be collected on the indemnified asset, ASU 2012-06 requires the entity to recognize the change in the measurement of the indemnification asset on the same basis as the indemnified assets. Any amortization of changes in value of the indemnification asset should be limited to the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets. ASU 2012-06 is effective for fiscal years beginning on or after December 15, 2012, and early adoption is permitted. It is to be applied prospectively to any new indemnification assets acquired after the date of adoption and to indemnification assets existing as of the date of adoption arising from a government-assisted acquisition of a financial institution. ASU 2012-06 did not have a material effect on the Company’s results of operations, financial position or disclosures. ASU 2011-04 – Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”). ASU 2011-04 generally represents clarifications of Topic 820, but also includes some instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. ASU 2011-04 results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements. ASU 2011-04 was to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011 for public companies. It did not have a material impact on the Company’s results of operations, financial position or disclosures. ASU 2011-05 – Amendments to Topic 220, Comprehensive Income (“ASU 2011-05”). ASU 2011-05 grants an entity the option 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. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income and a total amount for comprehensive income. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. ASU 2011-05 does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. For public entities, ASU 2011-05 was effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and was to be adopted retrospectively. It did not have a material impact on the Company’s results of operations, financial position or disclosures. ASU 2011-08 – Intangibles – Goodwill and Other (Topic 350) Testing Goodwill for Impairment (“ASU 2011-08”). ASU 2011-08 grants an entity the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This conclusion can be used as a basis for determining whether it is necessary to perform the two-step goodwill impairment test required in Topic 350. ASU 2011-08 was effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. It did not have a material impact on the Company’s results of operations, financial position or disclosures.
Fair Value of Financial Instruments	*Fair Value of Financial Instruments* The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair value is based on discounted cash flows or other valuation techniques. These techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The accounting standard for disclosures about the fair value of financial instruments excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The Company has elected to record mortgage loans held-for-sale at fair value in order to eliminate the complexities and inherent difficulties of achieving hedge accounting and to better align reported results with the underlying economic changes in value of the loans and related hedge instruments. This election impacts the timing and recognition of origination fees and costs, as well as servicing value, which are now recognized in earnings at the time of origination. Interest income on mortgage loans held-for-sale is recorded on an accrual basis in the consolidated statement of income under the heading “Interest income – interest and fees on loans”. The servicing value is included in the fair value of the Interest Rate Lock Commitments with borrowers. The mark to market adjustments related to loans held-for-sale and the associated economic hedges are captured in mortgage banking activities. The fair value hierarchy describes three levels of inputs that may be used to measure fair value: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments and other accounts recorded based on their fair value:
Cash and Due from Banks, Federal Funds Sold and Interest-Bearing Accounts	Cash and Due From Banks, Federal Funds Sold and Interest-Bearing Accounts: The carrying amount of cash and due from banks, federal funds sold and interest-bearing accounts approximates fair value.
Investment Securities Available for Sale	Investment Securities Available for Sale: The fair value of securities available for sale is determined by various valuation methodologies. Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Level 2 securities include mortgage-backed securities issued by government sponsored enterprises and municipal bonds. The level 2 fair value pricing is provided by an independent third-party and is based upon similar securities in an active market. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy and include certain residual municipal securities and other less liquid securities.
Other Investments	Other Investments: Federal Home Loan Bank (“FHLB”) stock is included in other investments at its original cost basis, as cost approximates fair value and there is no ready market for such investments.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale: The fair value of mortgage loans held for sale is determined on outstanding commitments from third party investors in the secondary markets and is classified within Level 2 of the valuation hierarchy.
Loans	Loans: The carrying amount of variable-rate loans that reprice frequently and have no significant change in credit risk approximates fair value. The fair value of fixed-rate loans is estimated based on discounted contractual cash flows, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The fair value of impaired loans is estimated based on discounted expected future cash flows or underlying collateral values, where applicable. A loan is determined to be impaired if the Company believes it is probable that all principal and interest amounts due according to the terms of the loan will not be collected as scheduled. The fair value of impaired loans is determined in accordance with accounting standards and generally results in a specific reserve established through a charge to the provision for loan losses. Losses on impaired loans are charged to the allowance when management believes the uncollectability of a loan is confirmed. Management has determined that the majority of impaired loans are Level 3 assets due to the extensive use of market appraisals. To the extent that market appraisals or other methods do not produce reliable determinations of fair value, these assets are deemed to be Level 3.
Other Real Estate Owned	Other Real Estate Owned: The fair value of other real estate owned (“OREO”) is determined using certified appraisals that value the property at its highest and best uses by applying traditional valuation methods common to the industry. The Company does not hold any OREO for profit purposes and all other real estate is actively marketed for sale. In most cases, management has determined that additional write-downs are required beyond what is calculable from the appraisal to carry the property at levels that would attract buyers. Because this additional write-down is not based on observable inputs, management has determined that other real estate owned should be classified as Level 3.
Covered Assets	Covered Assets: Covered assets include loans and other real estate owned on which the majority of losses would be covered by loss-sharing agreements with the Federal Deposit Insurance Corporation (the “FDIC”). Management initially valued these assets at fair value using mostly unobservable inputs and, as such, has classified these assets as Level 3.
Intangible Assets and Goodwill	Intangible Assets and Goodwill: Intangible assets consist of core deposit premiums acquired in connection with business combinations and are based on the established value of acquired customer deposits. The core deposit premium is initially recognized based on a valuation performed as of the consummation date and is amortized over an estimated useful life of three to ten years. Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangible assets deemed to have an indefinite useful life are not amortized but instead are subject to an annual review for impairment.
FDIC Loss-Share Receivable	FDIC Loss-Share Receivable: Because the FDIC will reimburse the Company for certain acquired loans should the Company experience a loss, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans and measured on the same basis, subject to collectability or contractual limitations. The shared-loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate which reflects counterparty credit risk and other uncertainties. The shared-loss agreements continue to be measured on the same basis as the related indemnified loans, and the loss-share receivable is impacted by changes in estimated cash flows associated with these loans.
Deposits	Deposits: The carrying amount of demand deposits, savings deposits and variable-rate certificates of deposit approximates fair value. The fair value of fixed-rate certificates of deposit is estimated based on discounted contractual cash flows using interest rates currently offered for certificates with similar maturities.
Securities Sold under Agreements to Repurchase and Other Borrowings	Securities Sold under Agreements to Repurchase and Other Borrowings: The carrying amount of variable rate borrowings and securities sold under repurchase agreements approximates fair value. The fair value of fixed rate other borrowings is estimated based on discounted contractual cash flows using the current incremental borrowing rates for similar borrowing arrangements.
Subordinated Deferrable Interest Debentures	Subordinated Deferrable Interest Debentures: The carrying amount of the Company’s variable rate trust preferred securities approximates fair value.
Off-Balance-Sheet Instruments	Off-Balance-Sheet Instruments: Because commitments to extend credit and standby letters of credit are typically made using variable rates and have short maturities, the carrying value and fair value are immaterial for disclosure.
Derivatives	Derivatives: The Company has entered into derivative financial instruments to manage interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivatives. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair value of the derivatives are determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates (forward curves derived from observable market interest rate curves). The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting any applicable credit enhancements such as collateral postings, thresholds, mutual puts and guarantees. Although the Company has determined that the majority of the inputs used to value its derivative fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself or the counterparty. However, as of September 30, 2013, December 31, 2012 and September 30, 2012, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustment is not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuation in its entirety is classified in Level 2 of the fair value hierarchy.
Deteriorated Loans Transferred Policy	FASB ASC 310 – 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310”), applies to a loan with evidence of deterioration of credit quality since origination, acquired by completion of a transfer for which it is probable, at acquisition, that the investor will be unable to collect all contractually required payments receivable. ASC 310 prohibits carrying over or creating an allowance for loan losses upon initial recognition for loans which fall under the scope of this statement. At the acquisition dates, a majority of these loans were valued based on the liquidation value of the underlying collateral because the future cash flows are primarily based on the liquidation of underlying collateral. There was no allowance for credit losses established related to these ASC 310 loans at the acquisition dates, based on the provisions of this statement. Over the life of the acquired loans, the Company continues to estimate cash flows expected to be collected. If the expected cash flows expected to be collected increases, then the Company adjusts the amount of accretable discount recognized on a prospective basis over the loan’s remaining life. If the expected cash flows expected to be collected decreases, then the Company records a provision for loan loss in its consolidated statement of operations.
