(1) The estimated fair value of derivatives with customers was $9.8 million and $25.4 million as of December 31, 2021 and December 31, 2020, respectively. The estimated fair value of derivatives with third-parties was $(9.8) million and $(25.9) million as of December 31, 2021 and December 31, 2020, respectively.
Generally, the gains and losses of the interest rate derivatives offset due to the back-to-back nature of the contracts. However, the settlement values of the Bank's net derivative assets with customers were increased by $355,000 and reduced by $422,000 as of December 31, 2021 and December 31, 2020, respectively, due to the recognition of a credit valuation adjustment. A credit valuation adjustment was not recorded on the Bank's net derivative assets as of December 31, 2019.
