The balance represents the amount of loans that are secured by real estate mortgages, offset by any reserve to cover probable credit losses on the loan portfolio and deduction of deferred fees, unamortized costs, premiums and discounts from the face amounts. Included in this account is investment in unconsolidated joint venture which reflects the carrying amount on the entity's balance sheet of its investment in common stock of an equity method investee. This is not an indicator of the fair value of the investment, rather it is the initial cost adjusted for the entity's share of earnings and losses of the investee, adjusted for any distributions (dividends) and other than temporary impairment (OTTI) losses recognized.
