Commercial loans held for sale consists primarily of mortgage warehouse loans. These mortgage warehouse lending transactions are subject to master repurchase agreements and are designated as held for sale and reported at fair value based on an election made to account for these loans at fair value. Pursuant to the master repurchase agreements, Customers funds the pipelines for these mortgage lenders by sending cash payments directly to the closing agents for funded loans (i.e., the purchase event) and receives proceeds directly from third-party investors when the loans are sold into the secondary market (i.e., the sale event). The fair values of the mortgage warehouse loans are estimated as the amount of cash initially advanced to fund the underlying mortgage, plus accrued interest and fees, as specified in the respective agreements. The interest rates on these loans are variable; and the lending transactions are short-term, with an average life of 22 days from purchase to sale. The primary goal of these lending transactions is to provide liquidity to mortgage companies. Effective June 30, 2017, Customers Bank transferred $150.6 million of multi-family loans from loans receivable (held for investment) to loans held for sale. Customers Bank transferred these loans at their carrying value, which was lower than the estimated fair value at the time of transfer. At December 31, 2017, the carrying value of these loans approximates their fair value. Accordingly, a lower of cost or fair value adjustment was not recorded as of December 31, 2017. Effective December 31, 2016, Customers Bank transferred $25.1 million of multi-family loans from held for sale to loans receivable (held for investment) because the Bank no longer had the intent to sell these loans. Customers Bank transferred these loans at their carrying value, which was lower than the estimated fair value at the time of transfer.
