The net book value of the property was $31.6 million at the time of the sale, resulting in a pre-tax gain of $85.4 million after considering $3.6 million in selling costs. As the leaseback is an operating lease, $71.7 million of the gain was recognized on the closing date, and $13.7 million was deferred and will be recognized over the term of the lease agreement. In the third quarter of 2017, the Company sold the insurance brokerage business of its subsidiary, East West Insurance Services, Inc. (“EWIS”), for $4.3 million, and recorded a pre-tax gain of $3.8 million. EWIS remains a subsidiary of East West and continues to maintain its insurance broker license. The Company reports a business as held-for-sale when management has approved or received approval to sell the business and is committed to a formal plan, the business is available for immediate sale, the business is being actively marketed, the sale is anticipated to occur during the next 12 months and certain other specific criteria are met. A business classified as held-for-sale is recorded at the lower of its carrying amount or estimated fair value less costs to sell. If the carrying amount of the business exceeds its estimated fair value, a loss is recognized. Depreciation and amortization expense is not recorded with respect to the assets of a business after it is classified as held-for-sale. On November 11, 2017, the Bank entered into a Purchase and Assumption Agreement to sell all of its eight Desert Community Bank (“DCB”) branches located in the High Desert area of Southern California to Flagstar Bank, a wholly-owned subsidiary of Flagstar Bancorp, Inc.
