Derivatives and Hedging

The Company is a party to derivative instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates and foreign currency exchange rates. The Company has made an accounting policy decision not to offset derivative fair value amounts under master netting agreements. See Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, for additional information on the Company's accounting policies related to derivative instruments and hedging activities. For derivatives cleared through central clearing houses the variation margin payments made are legally characterized as settlements of the derivatives. As a result, these variation margin payments are netted against the fair value of the respective derivative contracts in the balance sheet and related disclosures. The following table reflects the notional amount and fair value of derivative instruments included on the Company’s Unaudited Condensed Consolidated Balance Sheets on a gross basis.

Hedging Derivatives

The Company uses derivative instruments to manage the risk of earnings fluctuations caused by interest rate volatility. For those financial instruments that qualify and are designated as a hedging relationship, either a fair value hedge or cash flow hedge, the effect of interest rate movements on the hedged assets or liabilities will generally be offset by change in fair value of the derivative instrument.

Fair Value Hedges

The Company enters into fair value hedging relationships using interest rate swaps to mitigate the Company’s exposure to losses in value as interest rates change. Derivative instruments that are used as part of the Company’s interest rate risk management strategy include interest rate swaps that relate to the pricing of specific balance sheet assets and liabilities.

Interest rate swaps are used to convert the Company’s fixed rate long-term debt to a variable rate. The critical terms of the interest rate swaps match the terms of the corresponding hedged items. All components of each derivative instrument’s gain or loss are included in the assessment of hedge effectiveness.

The Company recognized no gains or losses for the three months ended March 31, 2018 and 2017, related to hedged firm commitments no longer qualifying as a fair value hedge. At March 31, 2018, the fair value hedges had a weighted average expected remaining term of 4.3 years.

The following table reflects the change in fair value for interest rate contracts and the related hedged items as well as other gains and losses related to fair value hedges including gains and losses recognized because of hedge ineffectiveness.

Other gains on interest rate contracts:
Interest and amortization related to interest rate swaps on hedged long term debt	Interest on FHLB and other borrowings	3,445			8,864

Cash Flow Hedges

The Company enters into cash flow hedging relationships using interest rate swaps and options, such as caps and floors, to mitigate exposure to the variability in future cash flows or other forecasted transactions associated with its floating rate assets and liabilities. The Company uses interest rate swaps and options to hedge the repricing characteristics of its floating rate commercial loans and FHLB advances. The Company also uses foreign currency forward contracts to hedge its exposure to fluctuations in foreign currency exchange rates due to a portion of money transfer expense being denominated in foreign currency. All components of each derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. The initial assessment of expected hedge effectiveness is based on regression analysis. The ongoing periodic measures of hedge ineffectiveness are based on the expected change in cash flows of the hedged item caused by changes in the benchmark interest rate. There were no gains or losses reclassified from other comprehensive income because of the discontinuance of cash flow hedges related to certain forecasted transactions that are probable of not occurring for the three months ended March 31, 2018 and 2017.

At March 31, 2018, cash flow hedges not terminated had a net fair value of $(2.0) million and a weighted average life of 0.5 years. Net losses of $38.5 million are expected to be reclassified to income over the next 12 months as net settlements occur. The maximum length of time over which the entity is hedging its exposure to the variability in future cash flows for forecasted transactions is 3.3 years.

The following table presents the effect of derivative instruments designated and qualifying as cash flow hedges on the Company’s Unaudited Condensed Consolidated Balance Sheets and the Company’s Unaudited Condensed Consolidated Statements of Income.

Derivatives Not Designated As Hedges

Derivatives not designated as hedges include those that are entered into as either economic hedges to facilitate client needs or as part of the Company’s overall risk management strategy. Economic hedges are those that do not qualify to be treated as a fair value hedge, cash flow hedge or foreign currency hedge for accounting purposes, but are necessary to economically manage the risk exposure associated with the assets and liabilities of the Company. The Company holds a portfolio of futures, forwards and interest rate lock commitments as well as options related to its equity-linked CDs to mitigate its economic risk exposure. The Company also enters into a variety of interest rate contracts and foreign exchange contracts in its trading activities. See Note 14, Derivatives and Hedging, in the Notes to the December 31, 2017, Consolidated Financial Statements for a description of the Company's derivatives not designated as hedges.

The net gains and losses recorded in the Company's Unaudited Condensed Consolidated Statements of Income from free-standing derivative instruments not designated as hedging instruments are summarized in the following table.

Derivatives Credit and Market Risks

By using derivative instruments, the Company is exposed to credit and market risk. If the counterparty fails to perform, credit risk is equal to the extent of the Company’s fair value gain in a derivative. When the fair value of a derivative instrument contract is positive, this generally indicates that the counterparty owes the Company and, therefore, creates a credit risk for the Company. When the fair value of a derivative instrument contract is negative, the Company owes the counterparty and, therefore, it has no credit risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically. Credit losses are also mitigated through collateral agreements and other contract provisions with derivative counterparties.

Market risk is the adverse effect that a change in interest rates or implied volatility rates has on the value of a financial instrument. The Company manages the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken.

The Company’s derivatives activities are monitored by its Asset/Liability Committee as part of its risk-management oversight. The Company’s Asset/Liability Committee is responsible for mandating various hedging strategies that are developed through its analysis of data from financial simulation models and other internal and industry sources. The resulting hedging strategies are then incorporated into the Company’s overall interest rate risk management and trading strategies.

Entering into interest rate swap agreements and options involves not only the risk of dealing with counterparties and their ability to meet the terms of the contracts but also interest rate risk associated with unmatched positions. At March 31, 2018, interest rate swap agreements and options classified as trading were substantially matched. The Company had credit risk of $124 million related to derivative instruments in the trading account portfolio, which does not take into consideration master netting arrangements or the value of the collateral. There were no credit losses associated with derivative instruments classified as trading for the three months ended March 31, 2018 and 2017. At March 31, 2018 and December 31, 2017, there were no material nonperforming derivative positions classified as trading.

The Company’s derivative positions designated as hedging instruments are primarily executed in the over-the-counter market. These positions at March 31, 2018, have credit risk of $15 million, which does not take into consideration master netting arrangements or the value of the collateral.

There were no credit losses associated with derivative instruments classified as nontrading for the three months ended March 31, 2018 and 2017. At March 31, 2018 and December 31, 2017, there were no nonperforming derivative positions classified as nontrading.

As of March 31, 2018 and December 31, 2017, the Company had recorded the right to reclaim cash collateral of $80 million and $92 million, respectively, within other assets on the Company’s Unaudited Condensed Consolidated Balance Sheets and had recorded the obligation to return cash collateral of $39 million and $24 million, respectively, within deposits on the Company’s Unaudited Condensed Consolidated Balance Sheets.

Contingent Features

Certain of the Company’s derivative instruments contain provisions that require the Company’s debt maintain a certain credit rating from each of the major credit rating agencies. If the Company’s debt were to fall below this rating, it would be in violation of these provisions, and the counterparties to the derivative instruments could demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on March 31, 2018, was $21 million for which the Company has collateral requirements of $20 million in the normal course of business. If the credit risk-related contingent features underlying these agreements had been triggered on March 31, 2018, the Company’s collateral requirements to its counterparties would require an additional increase of $1 million. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position on December 31, 2017, was $31 million for which the Company had collateral requirements of $30 million in the normal course of business. If the credit risk-related contingent features underlying these agreements had been triggered on December 31, 2017, the Company’s collateral requirements to its counterparties would have increased by $1 million.

Netting of Derivative Instruments

The Company is party to master netting arrangements with its financial institution counterparties for some of its derivative and hedging activities. The Company does not offset assets and liabilities under these master netting arrangements for financial statement presentation purposes. The master netting arrangements provide for single net settlement of all derivative instrument arrangements, as well as collateral, in the event of default with respect to, or termination of, any one contract with the respective counterparties. Cash collateral is usually posted by the counterparty with a net liability position in accordance with contract thresholds.

The following table represents the Company’s total gross derivative instrument assets and liabilities subject to an enforceable master netting arrangement. The derivative instruments the Company has with its customers are not subject to an enforceable master netting arrangement.
