We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate risk, primarily by managing the amount, source, and duration of our assets and liabilities, and through the use of derivative instruments. Derivative instruments are used to reduce the effects that changes in interest rates may have on net income and cash flows. We also use derivative instruments to facilitate transactions on behalf of our customers.

All derivatives are carried on the Consolidated Balance Sheets at fair value and do not take into account the effects of master netting arrangements we have with other financial institutions. Credit risk is included in the determination of the estimated fair value of derivatives. Derivative assets are reported in the Consolidated Balance Sheets in other assets and derivative liabilities are reported in the Consolidated Balance Sheets in other liabilities. Changes in fair value are recognized in earnings except for certain changes related to derivative instruments designated as part of a cash flow hedging relationship.

Certain derivative exchanges have enacted a rule change which in effect results in the legal characterization of variation margin payments for certain derivative contracts as settlement of the derivatives mark-to-market exposure and not collateral. Accordingly, we have changed our reporting of certain derivatives to record variation margin on trades cleared through these exchanges as settled. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

Interest Rate Contracts. We entered into interest rate derivative agreements to modify the interest rate characteristics of certain commercial loans and certain of our FHLB advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges, hedging the exposure to variability in expected future cash flows. The derivative’s gain or loss, including any ineffectiveness, is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same line item associated with the forecasted transaction when the forecasted transaction affects earnings. Prior to 2019, any ineffective portion of the gain or loss was reported in earnings immediately.

As of December 31, 2019, the maximum length of time over which forecasted interest cash flows are hedged is 4.9 years. In the twelve months that follow December 31, 2019, we expect to reclassify from the amount currently reported in AOCI net derivative gains of $4.5 million ($3.5 million net of tax), in association with interest on the hedged loans and FHLB advances. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to December 31, 2019.

There were no components of derivative gains or losses excluded from the assessment of hedge effectiveness related to these cash flow hedges. Also, during the years ended December 31, 2019 and 2018, there were no gains or losses from cash flow hedge derivatives reclassified to earnings because it became probable that the original forecasted transactions would not occur.

Interest Rate Swaps. We enter into interest rate swap agreements to meet the financing, interest rate and equity risk management needs of qualifying commercial loan customers. These agreements provide the customer the ability to convert from variable to fixed interest rates. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. Swap derivative transactions with customers are not subject to enforceable master netting arrangements and are generally secured by rights to non-financial collateral, such as real and personal property.

We enter into positions with a derivative counterparty in order to offset our exposure on the fixed components of the customer interest rate swap agreements. We seek to minimize counterparty credit risk by entering into transactions only with high-quality financial dealer institutions.

The interest rate swap agreement with the loan customer and with the counterparty is reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as other income or other expense.

Interest Rate Lock Commitments. Interest rate lock commitments represent an agreement to extend credit to a mortgage loan borrower, or an agreement to purchase a loan from a third-party originator, whereby the interest rate on the loan is set prior to funding. We are bound to fund the loan at a specified rate, regardless of whether interest rates have changed between the commitment date and the loan funding date, subject to the loan approval process. The borrower is not obligated to perform under the commitment. As such, outstanding IRLCs subject us to interest rate risk and related price risk during the period from the commitment to the borrower through the loan funding date, or commitment expiration. The IRLCs generally range between 30 to 270 days. The IRLCs are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as mortgage banking operations income.

Forward Delivery Commitments. Forward delivery commitments on mortgage-backed securities are used to manage the interest rate and price risk of our IRLCs and mortgage loan held for sale inventory by fixing the forward sale price that will be realized upon sale of the mortgage loans into the secondary market. Historical commitment-to-closing ratios are considered to estimate the quantity of mortgage loans that will fund within the terms of the IRLCs. The forward delivery contracts are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as mortgage banking operations income.

Credit Risk Contracts. We purchase and sell credit protection under risk participation agreements to share with other counterparties some of the credit exposure related to interest rate derivative contracts or to take on credit exposure to generate revenue. We will make/receive payments under these agreements if a customer defaults on their obligation to perform under certain derivative swap contracts.

Risk participation agreements sold with notional amounts totaling $201.5 million as of December 31, 2019 have remaining terms ranging from two months to nine years. Under these agreements, our maximum exposure assuming a customer defaults on their obligation to perform under certain derivative swap contracts with third parties would be $0.3 million and $0.1 million at December 31, 2019 and 2018, respectively. The fair values of risk participation agreements purchased and sold were $0.1 million and $0.3 million, respectively, at December 31, 2019 and $0.05 million and $0.11 million, respectively, at December 31, 2018.

We are party to master netting arrangements with most of our swap derivative dealer counterparties. Collateral, usually marketable securities and/or cash, is exchanged between FNB and our counterparties, and is generally subject to thresholds and transfer minimums. For swap transactions that require central clearing, we post cash to our clearing agency. Collateral positions are settled or valued daily, and adjustments to amounts received and pledged by us are made as appropriate to maintain proper collateralization for these transactions.

Certain master netting agreements contain provisions that, if violated, could cause the counterparties to request immediate settlement or demand full collateralization under the derivative instrument. If we had breached our agreements with our derivative counterparties we would be required to settle our obligations under the agreements at the termination value and would be required to pay an additional $0.1 million and $0.7 million as of December 31, 2019 and 2018, respectively, in excess of amounts previously posted as collateral with the respective counterparty.
