15. Commitments and Contingencies Repurchase Contingencies . The Company is contingently liable under terms of repurchase agreements with financial institutions providing inventory financing for independent retailers of its products. These arrangements, which are customary in the industry, provide for the repurchase of products sold to retailers in the event of default by the retailer. The risk of loss under these agreements is spread over numerous retailers. The price the Company is obligated to pay generally declines over the period of the agreement (generally 18 to 36 months , calculated from the date of sale to the retailer) and the risk of loss is further reduced by the resale value of the repurchased homes. The Company applies ASC 460 and ASC 450-20 to account for its liability for repurchase commitments. Under the provisions of ASC 460, issuance of a guarantee results in two different types of obligations: (1) a non-contingent obligation to stand ready to perform under the repurchase commitment (accounted for pursuant to ASC 460) and (2) a contingent obligation to make future payments under the conditions of the repurchase commitment (accounted for pursuant to ASC 450-20). Management reviews the retailers' inventories to estimate the amount of inventory subject to repurchase obligation, which is used to calculate: (1) the fair value of the non-contingent obligation for repurchase commitments and (2) the contingent liability based on historical information available at the time. During the period in which a home is sold (inception of a repurchase commitment), the Company records the greater of these two calculations as a liability for repurchase commitments and as a reduction to revenue. (1) The Company estimates the fair value of the non-contingent portion of its manufacturer's inventory repurchase commitment under the provisions of ASC 460 when a home is shipped to retailers whose floor plan financing includes a repurchase commitment. The fair value of the inventory repurchase agreement is determined by c
