[1] In addition to the valuation techniques and unobservable inputs discussed above, at December 31, 2018, we had an impaired collateral dependent commercial relationship that totaled $0.7 million that was secured by collateral other than real estate. Collateral securing this relationship primarily included accounts receivable, inventory and cash at December 31, 2018. Valuation techniques at December 31, 2018, included discounting financial statement values for each particular asset type. Discount rates used ranged from 20% to 80% of stated values.
