[1] Fair values represent the amount at which an asset could be sold in an orderly transaction between a willing buyer and willing seller. The immediate liquidation value of these assets would likely be substantially lower.

[2] Amount at risk is calculated on an asset-by-asset basis for the facility and considers the greater of (a) the book value of an asset and (b) the fair value of an asset, in determining the total risk.
