i. Revenue Recognition 1) Interest income We recognize interest income from investments in commercial mortgage loans, mezzanine loans, and preferred equity interests on a yield to maturity basis. Certain of our commercial mortgage loans, mezzanine loans and preferred equity interests provide for the accrual of interest at specified rates which differ from current payment terms. Interest income is recognized on such loans at the accrual rate subject to managements determination that accrued interest and outstanding principal are ultimately collectible. Management will cease accruing interest on these loans when it determines that the interest income may not be collectible based on the ultimate value of the underlying collateral using discounted cash flow models and market based assumptions. The accrued interest receivable associated with these loans as of June 30, 2016 and December 31, 2015 was $28,358 and $34,132, respectively. These loans are considered to be impaired when the total amount owed exceeds the estimated value of the underlying collateral. None of these loans were considered to be impaired as of June 30, 2016 and December 31, 2015. Origination fees and direct loan origination costs on our investments in commercial mortgages, mezzanine loans and preferred equity interests are deferred and amortized to investment interest income, using the effective interest method, over the contractual life of the underlying loan security or loan, in accordance with FASB ASC Topic 310, Receivables. 2) Property income We generate property income from tenant rent and other tenant-related activities at our consolidated real estate properties. For multi-family real estate properties, property income is recorded when due from residents and recognized monthly as it is earned and realizable, under lease terms which are generally for periods of one year or less. For retail and office real estate properties, property income is recognized on a straight-line basis from the later of the date of the commencement of the lease
