Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	4. Earnings per Share Basic earnings per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock and resulted in the issuance of common stock that then shared in earnings. Outstanding stock options with anti-dilutive effect were not included in the computation of diluted earnings per share. The following table sets forth earnings per common share calculations: Three months ended June 30, Six months ended June 30, (Dollars in thousands, except share and per share data) 2015 2014 2015 2014 Net income $ 45,200 $ 35,084 $ 81,180 $ 66,343 Weighted-average shares: Basic weighted-average number of common shares outstanding 79,939,197 79,642,993 79,887,699 79,619,506 Dilutive effect of weighted-average outstanding common share equivalents Warrants 566,405 273,759 456,274 286,079 Options 139,867 97,476 124,249 99,575 Restricted stock units 53,525 32,243 37,043 37,786 Diluted weighted-average number of common shares outstanding 80,698,994 80,046,471 80,505,265 80,042,946 Average stock options and warrants with anti-dilutive effect 939,615 2,003,896 1,246,123 1,994,922 Earnings per common share: Basic $ 0.57 $ 0.44 $ 1.02 $ 0.83 Diluted $ 0.56 $ 0.44 $ 1.01 $ 0.83

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	5. Stock-Based Compensation Under the Company’s equity incentive plans, directors and eligible employees may be granted incentive or non-statutory stock options and/or restricted stock units, or awarded non-vested stock. As of June 30, 2015, the only options granted by the Company were non-statutory stock options to selected Bank officers and non-employee directors at exercise prices equal to the fair market value of a share of the Company’s common stock on the date of grant. Such options have a maximum ten-year term and vest in 20% annual increments (subject to early termination in certain events) except certain options granted to the Chief Executive Officer of the Company in 2005 and 2008. If such options expire or terminate without having been exercised, any shares not purchased will again be available for future grants or awards. There were no options granted during the first six months of 2015 or during 2014. Option compensation expense was zero for the three months and for the six months ended June 30, 2015, and June 30, 2014. Stock-based compensation was fully recognized over the requisite service period for all awards. Stock options covering 73,350 shares were exercised in the six months ended June 30, 2015, compared to zero in the six months ended June 30, 2014. Cash received totaled $1.7 million and the aggregate intrinsic value totaled $556,000 from the exercise of stock options during the first six months ended June 30, 2015. The table below summarizes stock option activity for the periods indicated: Weighted-average Aggregate Weighted-average Remaining Contractual Intrinsic Shares Exercise Price Life (in years) Value (in thousands) Balance, December 31, 2014 2,332,904 $ 32.34 1.2 $ 1,388 Exercised (3,750 ) 23.37 Forfeited (808,670 ) 35.63 Balance, March 31, 2015 1,520,484 $ 30.62 1.6 $ 3,156 Exercised (69,600 ) 23.37 Forfeited (267,884 ) 33.99 Balance, June 30, 2015 1,183,000 $ 30.37 1.5 $ 5,010 Exercisable, June 30, 2015 1,183,000 $ 30.37 1.5 $ 5,010 In addition to stock options, the Company also grants restricted stock units to eligible employees which vest subject to continued employment at the vesting dates. The Company granted restricted stock units for 72 ,900 shares at an average closing price of $28.11 per share in the first six months of 2015 compared to 17,601 shares at an average closing price of $24.66 per share in 2014. The restricted stock units granted are scheduled to vest two years from grant date for 2014 grants and to vest three years from grant date for 2015 grants. The Company granted performance share unit awards in which the number of units earned is calculated based on the relative total shareholder return (“TSR”) of the Company’s common stock as compared to the TSR of the KBW Regional Banking Index. In addition, the Company granted performance share unit awards in which the number of units earned is determined by comparison to the targeted EPS as defined in the award for the next three years. In December 2014, the Company granted performance TSR restricted stock units for 60,456 shares and performance EPS restricted stock units for 57,642 shares to six executive officers. Both the performance TSR and performance EPS units awarded in 2014 are scheduled to vest at December 31, 2017.

The contractual terms of those investments do not permit the issuers to settle the security at a price less than the amortized cost of the investment. At June 30, 2015, management believed the impairment was temporary and, accordingly, no impairment loss on debt securities has been recognized in our condensed consolidated statements of operations. The Company expects to recover the amortized cost basis of its debt securities, and has no intent to sell and will not be required to sell available-for-sale debt securities that have declined below their cost before their anticipated recovery. Investment securities having a carrying value of $519.2 million at June 30, 2015, and $591.3 million at December 31, 2014, were pledged to secure public deposits, other borrowings, treasury tax and loan, and securities sold under agreements to repurchase.

The Company has no specific industry concentration, and generally its loans are secured by real property or other collateral of the borrowers. Loans are generally expected to be paid off from the operating profits of the borrowers, from refinancing by other lenders, or through sale by the borrowers of the secured collateral. The components of loans in the condensed consolidated balance sheets as of June 30, 2015, and December 31, 2014, were as follows: June 30, 2015 December 31, 2014 (In thousands) Type of Loans: Commercial loans $ 2,387,450 $ 2,382,493 Residential mortgage loans 1,713,312 1,570,059 Commercial mortgage loans 4,849,381 4,486,443 Equity lines 176,067 172,879 Real estate construction loans 370,828 298,654 Installment and other loans 4,970 3,552 Gross loans $ 9,502,008 $ 8,914,080 Less: Allowance for loan losses (153,437 ) (161,420 ) Unamortized deferred loan fees (10,207 ) (12,392 ) Total loans, net $ 9,338,364 $ 8,740,268 Loans held for sale $ - $ 973 At June 30, 2015, recorded investment in impaired loans totaled $166.1 million and was comprised of non-accrual loans of $66.1 million and accruing troubled debt restructured loans (“TDRs) of $100.0 million. At December 31, 2014, recorded investment in impaired loans totaled $174.5 million and was comprised of non-accrual loans of $70.2 million and accruing TDRs of $104.3 million. For impaired loans, the amounts previously charged off represent 18.6% at June 30, 2015, and 17.1% at December 31, 2014, of the contractual balances for impaired loans.

The nature of the process by which the Bank determines the appropriate allowance for credit losses requires the exercise of considerable judgment. This allowance evaluation process is also applied to troubled debt restructurings since they are considered to be impaired loans. A troubled debt restructuring is a formal modification of the terms of a loan when the lender, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, including a change in the stated interest rate, a reduction in the loan balance or accrued interest, or an extension of the maturity date that causes significant delay in payment. TDRs on accrual status are comprised of the loans that have, pursuant to the Bank’s policy, performed under the restructured terms and have demonstrated sustained performance under the modified terms for six months before being returned to accrual status. The sustained performance considered by management pursuant to its policy includes the periods prior to the modification if the prior performance met or exceeded the modified terms. This would include cash paid by the borrower prior to the restructure to set up interest reserves. At June 30, 2015, accruing TDRs were $100.0 million and non-accrual TDRs were $42.6 million compared to accruing TDRs of $104.3 million and non-accrual TDRs of $41.6 million at December 31, 2014. The Company allocated specific reserves of $1.4 million to accruing TDRs and $5.8 million to non-accrual TDRs at June 30, 2015, and $6.5 million to accruing TDRs and $4.9 million to non-accrual TDRs at December 31, 2014. The following tables present TDRs that were modified during the first six months of 2015 and of 2014, their specific reserve s at June 30, 2015, and 2014, and charge-off s during the first six months of 2015 and of 2014: Six months ended June 30, 2015 June 30, 2015 No. of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Charge-offs Specific Reserve (Dollars in thousands) Commercial loans 1 $ 850 $ 850 $ - $ - Commercial mortgage loans 4 14,411 14,411 - 40 Residential mortgage loans and equity lines 4 1,522 1,374 148 43 Total 9 $ 16,783 $ 16,635 $ 148 $ 83 Six months ended June 30, 2014 June 30, 2014 No. of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Charge-offs Specific Reserve (Dollars in thousands) Commercial loans 3 8,490 8,490 $ - $ 20 Residential mortgage loans and equity lines 3 1,393 1,393 - 32 Total 6 $ 9,883 $ 9,883 $ - $ 52 Modifications of the loan terms during the first six months of 2015 were in the form of changes in the stated interest rate, and/or extension of maturity dates, and/or reduction in monthly payment amount. The length of time for which modifications involving a reduction of the stated interest rate or changes in payment terms that were documented ranged from six months to three years from the modification date. We expect that the TDRs on accruing status as of June 30, 2015, which were all performing in accordance with their restructured terms, will continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. A summary of TDRs by type of concession and by type of loan, as of June 30, 2015, and December 31, 2014, is shown below: June 30, 2015 Accruing TDRs Payment Deferral Rate Reduction Rate Reduction and Payment Deferral Total (In thousands) Commercial loans $ 12,386 $ 1,496 $ 1,957 $ 15,839 Real estate construction loans - - 5,730 5,730 Commercial mortgage loans 29,465 6,082 34,055 69,602 Residential mortgage loans 5,088 1,005 2,747 8,840 Total accruing TDRs $ 46,939 $ 8,583 $ 44,489 $ 100,011 June 30, 2015 Non-accrual TDRs Payment Deferral Rate Reduction and Payment Deferral Total (In thousands) Commercial loans $ 2,272 $ - $ 2,272 Real estate construction loans 10,366 5,990 16,356 Commercial mortgage loans 1,566 20,540 22,106 Residential mortgage loans 611 1,250 1,861 Total non-accrual TDRs $ 14,815 $ 27,780 $ 42,595 December 31, 2014 Accruing TDRs Payment Deferral Rate Reduction Rate Reduction and Forgiveness of Principal Rate Reduction and Payment Deferral Total Commercial loans $ 11,572 $ - $ - $ 4,934 $ 16,506 Real estate construction loans 5,765 - - - 5,765 Commercial mortgage loans 20,543 26,694 - 26,351 73,588 Residential mortgage loans 3,316 - 410 4,771 8,497 Total accruing TDRs $ 41,196 $ 26,694 $ 410 $ 36,056 $ 104,356 December 31, 2014 Non-accrual TDRs Payment Deferral Rate Reduction Rate Reduction and Payment Deferral Total (In thousands) Commercial loans $ 1,423 $ 860 $ 1,269 $ 3,552 Real estate construction loans - - 19,462 19,462 Commercial mortgage loans 15,917 - 973 16,890 Residential mortgage loans 1,026 - 688 1,714 Total non-accrual TDRs $ 18,366 $ 860 $ 22,392 $ 41,618 The activity within our TDRs for the periods indicated are shown below: Three months ended June 30, Six months ended June 30, Accruing TDRs 2015 2014 2015 2014 (In thousands) Beginning balance $ 100,393 $ 118,922 $ 104,356 $ 117,597 New restructurings 5,798 722 16,426 8,097 Restructured loans restored to accrual status - - - 962 Charge-offs - - (148 ) - Payments (6,180 ) (1,278 ) (10,434 ) (8,290 ) Restructured loans placed on nonaccrual - (7,230 ) (10,189 ) (7,230 ) Ending balance $ 100,011 $ 111,136 $ 100,011 $ 111,136 Three months ended June 30, Six months ended June 30, Non-accrual TDRs 2015 2014 2015 2014 (In thousands) Beginning balance $ 44,541 $ 37,797 $ 41,618 $ 38,769 New restructurings - 247 209 1,786 Restructured loans placed on nonaccrual - 7,230 10,189 7,230 Charge-offs (489 ) (595 ) (3,243 ) (599 ) Payments (1,457 ) (1,074 ) (6,178 ) (2,619 ) Restructured loans restored to accrual status - - - (962 ) Ending balance $ 42,595 $ 43,605 $ 42,595 $ 43,605 A loan is considered to be in payment default once it is 60 to 90 days contractually past due under the modified terms. The Company had one commercial mortgage loan in the amount of $9.6 million that was modified as a TDR during the previous twelve months and which subsequently defaulted as of June 30, 2015. The Company had previously taken a charge off in the amount of $598,000 on this same commercial mortgage loan during the previous twelve months. Under the Company’s internal underwriting policy, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification in order to determine whether a borrower is experiencing financial difficulty. As of June 30, 2015, there were no commitments to lend additional funds to those borrowers whose loans had been restructured, were considered impaired, or were on non-accrual status. As part of the on-going monitoring of the credit quality of our loan portfolio, the Company utilizes a risk grading matrix to assign a risk grade to each loan. The risk rating categories can be generally described by the following grouping for non-homogeneous loans: ● Pass/Watch – ● Special Mention – ● Substandard – ● Doubtful – ● Loss – The Company had no loans held for sale as of June 30, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	8. Commitments and Contingencies The Company is involved in various litigation concerning transactions entered into in the normal course of business. Management, after consultation with legal counsel, does not believe that the resolution of such litigation will have a material effect upon its consolidated financial condition, results of operations, or liquidity taken as a whole. Although the Company establishes accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated, the Company does not have accruals for all legal proceedings where there is a risk of loss. In addition, amounts accrued may not represent the ultimate loss to the Company from the legal proceedings in question. Thus, ultimate losses may be higher or lower, and possibly significantly so, than the amounts accrued for legal loss contingencies. In the normal course of business, the Company becomes a party to financial instruments with off-balance sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit in the form of loans, or through commercial or standby letters of credit and financial guarantees. These instruments represent varying degrees of exposure to risk in excess of the amounts included in the accompanying condensed consolidated balance sheets. The contractual or notional amount of these instruments indicates a level of activity associated with a particular class of financial instrument and is not a reflection of the level of expected losses, if any.

Income Taxes Income tax expense totaled $31.1 million, or an effective tax rate of 27.7%, for the first six months of 2015, compared to an income tax expense of $38.6 million, or an effective tax rate of 36.8%, for the same period a year ago. The effective tax rate includes the impact of the utilization of low income housing tax credits for both periods. At June 30, 2015, the Company forecasted its effective tax rate for the full year 2015 to be 27.7%, including the utilization of alternative energy tax credits generated from an investment made in April 2015, and applied the forecasted full year effective tax rate to the results of operations for the first six months of 2015. As of December 31, 2014, the Company had income tax refunds receivable of $18.1 million. These income tax receivables are included in other assets in the accompanying condensed consolidated balance sheets.

Disclosure Text Block [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	11. Fair Value Measurements The Company adopted ASC Topic 820 on January 1, 2008, and determined the fair values of our financial instruments based on the following: ● Level 1 - Quoted prices in active markets for identical assets or liabilities. ● Level 2 - Observable prices in active markets for similar assets or liabilities; prices for identical or similar assets or liabilities in markets that are not active; directly observable market inputs for substantially the full term of the asset and liability; market inputs that are not directly observable but are derived from or corroborated by observable market data. ● Level 3 – Unobservable inputs based on the Company’s own judgment about the assumptions that a market participant would use. The Company uses the following methodologies to measure the fair value of its financial assets and liabilities on a recurring basis: Securities Available for Sale Warrants Foreign Exchange Contracts Interest Rate Swaps The valuation techniques for the assets and liabilities valued on a nonrecurring basis are as follows: Impaired Loans. Goodwill. — Commercial Lending and Retail Banking. The Company then completes “step one” of the impairment test by comparing the fair value of each reporting unit (as determined based on the discussion below) with the recorded book value (or “carrying amount”) of its net assets, with goodwill included in the computation of the carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary. If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test is performed to determine the amount of impairment. Step two of the impairment test compares the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill. The implied fair value of goodwill is computed by assuming that all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill. This adjusted goodwill balance is the implied fair value used in step two. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value. In connection with the determination of fair value, certain data and information is utilized, including earnings forecasts at the reporting unit level for the next four years. Other key assumptions include terminal values based on future growth rates and discount rates for valuing the cash flows, which have inputs for the risk-free rate, market risk premium, and adjustments to reflect inherent risk and required market returns. Because of the significance of unobservable inputs in the valuation of goodwill impairment, goodwill subject to nonrecurring fair value adjustments is classified as a Level 3 measurement.

The fair value adjustment of warrants was included in other operating income in the second quarter of 2015. The significant unobservable inputs in the Black-Scholes option pricing model for the fair value of warrants are their expected life ranging from 1 to 5 years, risk-free interest rate from 0.65% to 1.65%, and stock volatility from 10.0% to 13.7%.

The significant unobservable (Level 3) inputs used in the fair value measurement of collateral for collateral-dependent impaired loans was primarily based on the appraised value of collateral adjusted by estimated sales cost and commissions. The Company generally obtains new appraisal reports every nine months. As the Company’s primary objective in the event of default would be to monetize the collateral to settle the outstanding balance of the loan, less marketable collateral would receive a larger discount. During the reported periods, collateral discounts ranged from 55% in the case of accounts receivable collateral to 65% in the case of inventory collateral. The significant unobservable inputs used in the fair value measurement of loans held for sale was primarily based on the quoted price or sale price adjusted by estimated sales cost and commissions. The significant unobservable inputs used in the fair value measurement of other real estate owned (“OREO”) was primarily based on the appraised value of OREO adjusted by estimated sales cost and commissions. The Company applies estimated sales cost and commissions ranging from 3% to 6% to collateral value of impaired loans, quoted price, or loan sale price of loans held for sale, and appraised value of OREO.

Fair Value Disclosures [Text Block]	12. Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each class of financial instruments. Cash and Cash Equivalents. Short-term Investments. Securities Purchased under Agreements to Resell. Securities. Loans H eld for S ale Loans. The fair value of performing loans was calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, a Level 3 measurement. The fair value of impaired loans was calculated based on the net realizable fair value of the collateral or the observable market price of the most recent sale or quoted price from loans held for sale. The Company does not record loans at fair value on a recurring basis. Nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on the current appraised value or adjusted appraised of the collateral, a Level 2 or Level 3 measurement. Deposit Liabilities. Securities Sold under Agreements to Repurchase. Advances from Federal Home Loan Bank . Other Borrowings. Long-term Debt. Foreign Exchange Contracts Interest Rate Swaps Off-Balance-Sheet Financial Instruments. Fair value was estimated in accordance with ASC Topic 825. Fair value estimates were made at specific points in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates were based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates were subjective in nature and involved uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. The following table presents the carrying and notional amounts and estimated fair value of financial instruments as of June 30, 2015, and as of December 31, 2014: June 30, 2015 December 31, 2014 Carrying Carrying Amount Fair Value Amount Fair Value (In thousands) Financial Assets Cash and due from banks $ 166,933 $ 166,933 $ 176,830 $ 176,830 Short-term investments 48,711 48,711 489,614 489,614 Securities available-for-sale 1,545,699 1,545,699 1,318,935 1,318,935 Loans held for sale - - 973 1,225 Loans, net 9,338,364 9,271,167 8,740,268 8,688,072 Investment in Federal Home Loan Bank stock 17,250 17,250 30,785 30,785 Warrants 32 32 27 27 Notional Notional Amount Fair Value Amount Fair Value Foreign exchange contracts $ 193,066 $ 2,326 $ 167,005 $ 1,876 Financial Liabilities Carrying Carrying Amount Fair Value Amount Fair Value Deposits $ 9,338,863 $ 9,341,551 $ 8,783,460 $ 8,785,342 Securities sold under agreements to repurchase 400,000 419,915 450,000 473,816 Advances from Federal Home Loan Bank 210,000 210,020 425,000 424,974 Other borrowings 20,261 17,571 19,934 17,978 Long-term debt 119,136 59,015 119,136 59,425 Notional Notional Amount Fair Value Amount Fair Value Foreign exchange contracts $ 188,048 $ 3,201 $ 178,868 $ 5,007 Interest rate swaps 298,538 4,095 300,480 4,626 Notional Notional Amount Fair Value Amount Fair Value Off-Balance Sheet Financial Instruments Commitments to extend credit $ 2,003,486 $ (4,123 ) $ 2,071,766 $ (3,442 ) Standby letters of credit 50,293 (202 ) 53,910 (243 ) Other letters of credit 57,204 (35 ) 48,142 (29 ) Bill of lading guarantees 199 (1 ) 108 - The following tables present the level in the fair value hierarchy for the estimated fair values of financial instruments as of June 30, 2015, and December 31, 2014.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	13. Goodwill and Goodwill Impairment The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value. The Company first assesses 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 as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The two-step impairment testing process, if needed, begins by assigning net assets and goodwill to our two reporting units — Commercial Lending and Retail Banking. The Company then completes “step one” of the impairment test by comparing the fair value of each reporting unit (as determined based on the discussion below) with the recorded book value (or “carrying amount”) of its net assets, with goodwill included in the computation of the carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary. If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test is performed to determine the amount of impairment. Step two of the impairment test compares the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill. The implied fair value of goodwill is computed by assuming that all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill. This adjusted goodwill balance is the implied fair value used in step two. An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value. At June 30, 2015, the Company’s market capitalization was above book value and there was no triggering event that required the Company to assess goodwill for impairment as of an interim date.

Derivative Instrument Detail [Abstract]
Schedule of Derivative Instruments [Table Text Block]	14. Financial Derivatives It is the policy of the Company not to speculate on the future direction of interest rates. However, the Company enters into financial derivatives in order to seek mitigation of exposure to interest rate risks related to our interest-earning assets and interest-bearing liabilities. We believe that these transactions, when properly structured and managed, may provide a hedge against inherent interest rate risk in the Company’s assets or liabilities and against risk in specific transactions. In such instances, the Company may enter into interest rate swap contracts or other types of financial derivatives. Prior to considering any hedging activities, we seek to analyze the costs and benefits of the hedge in comparison to other viable alternative strategies. All hedges must be approved by the Bank’s Investment Committee. The Company follows ASC Topic 815 that establishes accounting and reporting standards for financial derivatives, including certain financial derivatives embedded in other contracts, and hedging activities. It requires the recognition of all financial derivatives as assets or liabilities in the Company’s consolidated balance sheet and measurement of those financial derivatives at fair value. The accounting treatment of changes in fair value is dependent upon whether or not a financial derivative is designated as a hedge and, if so, the type of hedge. Fair value is determined using third-party models with observable market data. For derivatives designated as cash flow hedges, changes in fair value are recognized in other comprehensive income and are reclassified to earnings when the hedged transaction is reflected in earnings. For derivatives designated as fair value hedges, changes in the fair value of the derivatives are reflected in current earnings, together with changes in the fair value of the related hedged item if there is a highly effective correlation between changes in the fair value of the interest rate swaps and changes in the fair value of the underlying asset or liability that is intended to be hedged. If there is not a highly effective correlation between changes in the fair value of the interest rate swap and changes in the fair value of the underlying asset or liability that is intended to be hedged, then only the changes in the fair value of the interest rate swaps are reflected in the Company’s consolidated financial statements. In May 2014, Bancorp entered into five interest rate swap contracts in the notional amount of $119.1 million for a period of ten years. The objective of these interest rate swap contracts, which were designated as hedging instruments in cash flow hedges, was to hedge on Bancorp’s $119.1 million of Junior Subordinated Debentures that had been issued to five trusts, the quarterly interest payments throughout the ten-year period beginning in June 2014 and ending in June 2024, from the risk of variability of these payments resulting from changes in the three-month LIBOR interest rate. Bancorp pays a weighted average fixed interest rate of 2.61% and receives a variable interest rate of the three-month LIBOR at a weighted average rate of 0.28%. As of June 30, 2015, the notional amount of cash flow interest rate swaps was $119.1 million and their unrealized loss of $1.7 million, net of taxes, was included in other comprehensive income. The amount of periodic net settlement of interest rate swaps included in interest expense was $703,000 for the three months ended June 30,2015 compared to $101,000 for the same quarter a year ago. For the six months ended June 30, 2015, the periodic net settlement of interest rate swaps included in interest expense was $1.4 million compared to $101,000 for the same period in 2014. In June 2014, the Bank entered into ten interest rate swap contracts in the notional amount of $148.1 million for various terms from four to eight years. In October 2014, the Bank entered into four additional interest rate swap contracts in the notional amount of $34.9 million. These interest rate swap contracts that are matched to individual fixed-rate commercial real estate loans in the Bank’s loan portfolio. These contracts have been designated as hedging instruments to hedge the risk of changes in the fair value of the underlying commercial real estate loan due to changes in interest rates. The swap contracts are structured so that the notional amounts reduce over time to match the contractual amortization of the underlying loan and allow prepayments with the same pre-payment penalty amounts as the related loan. The Bank pays a weighted average fixed rate of 4.60% and receives a variable rate at the one month LIBOR rate plus a weighted average spread of 292 basis points, or at a weighted average rate of 3.11%. As of June 30, 2015, the notional amount of fair value interest rate swaps was $179.4 million and their unrealized loss of $1.2 million was included in other non-interest income. The amount of periodic net settlement of interest rate swaps reducing interest income was $682,000 for the three months ended June 30, 2015, compared to $26,000 for the same quarter a year ago. The amount of periodic net settlement of interest rate swaps reducing interest income was $1.4 million for the six months ended June 30, 2015 compared to $26,000 for the same period a year ago. As of June 30, 2015, the ineffective portion of these interest rate swaps was not significant. Interest rate swap contracts involve the risk of dealing with institutional derivative counterparties and their ability to meet contractual terms. Institutional counterparties must have a strong credit profile and be approved by the Company’s Board of Directors. The Company’s credit exposure on interest rate swaps is limited to the net favorable value and interest payments of all swaps by each counterparty. Credit exposure may be reduced by the amount of collateral pledged by the counterparty. Bancorp’s interest rate swaps have been assigned by the counterparties to a derivatives clearing organization and daily margin is indirectly maintained with the derivatives clearing organization. Cash posted as collateral by Bancorp related to derivative contracts totaled $7.2 million as of June 30, 2015. The Company enters into foreign exchange forward contracts with various counterparties to mitigate the risk of fluctuations in foreign currency exchange rates for foreign exchange certificates of deposit or foreign exchange contracts entered into with our clients. These contracts are not designated as hedging instruments and are recorded at fair value in our condensed consolidated balance sheets. Changes in the fair value of these contracts as well as the related foreign exchange certificates of deposit and foreign exchange contracts are recognized immediately in net income as a component of non-interest income. Period end gross positive fair values are recorded in other assets and gross negative fair values are recorded in other liabilities. At June 30, 2015, spot, forward, and swap contracts in the total notional amount of $193.1 million had a positive fair value of $2.3 million. Spot, forward, and swap contracts in the total notional amount of $188.0 million had a negative fair value of $3.2 million at June 30, 2015. At December 31, 2014, spot, forward, and swap contracts in the total notional amount of $167.0 million had a positive fair value of $1.9 million. Spot, forward, and swap contracts in the total notional amount of $178.9 million had a negative fair value of $5.0 million at December 31, 2014.
