Our credit exposure on derivative instruments is limited to the net favorable value and interest payments by each counterparty. In some cases collateral may be required from the counterparties involved if the net value of the derivative instruments exceeds a nominal amount. Our credit exposure associated with these instruments, net of any collateral pledged, was approximately

$48.7 million at December 31, 2019 and approximately $18.7 million at December 31, 2018. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap and cap values, as well as for changes in the value of forward sale commitments. At December 31, 2019, we had $56.6 million in cash collateral pledged for these derivatives, of which $54.3 million was included in interest-bearing deposits in other banks and $2.3 million was included in accrued interest receivable and other assets. At December 31, 2018, we had $25.3 million in cash collateral pledged for these derivatives, of which $11.2 million was included in interest-bearing deposits and $14.1 million was included in accrued interest receivable and other assets.

We also enter into credit risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are either a participant or a lead bank. The risk participation agreements entered into by us as a participant bank provide credit protection to the financial institution counterparty should the borrower fail to perform on its interest rate derivative contract with that financial institution. We are party to 12 risk participation agreements where we are a participant bank with a notional amount of $146.7 million at December 31, 2019, compared to 13 risk participation agreements having a notional amount of $149.1 million at December 31, 2018. The maximum estimated exposure to these agreements, assuming 100% default by all obligors, was approximately $3.6 million at December 31, 2019 and $1.5 million at December 31, 2018. The fair value of these exposures was insignificant to the consolidated financial statements at both December 31, 2019 and December 31, 2018. Risk participation agreements entered into by us as the lead bank provide credit protection to us should the borrower fail to perform on its interest rate derivative contract with us. We are party to 12 risk participation agreements where we are the lead bank having a notional amount of $145.9 million at December 31, 2019, compared to 9 agreements having a notional amount of $114.8 million at December 31, 2018.
