[1] In addition to the valuation techniques and unobservable inputs discussed above, at June 30, 2022 and December 31, 2021 certain collateral dependent installment loans totaling approximately $0.20 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.
