[1] In addition to the valuation techniques and unobservable inputs discussed above, at March 31, 2022 and December 31, 2021 certain collateral dependent installment loans totaling approximately $0.16 million and $0.17 million, respectively are secured by collateral other than real estate. For the majority of these loans, we apply internal discount rates to industry valuation guides.
