[1] Position or portion thereof is an unfunded loan commitment, and no interest is being earned on the unfunded portion, although the investment may be subject to unused commitment fees. Negative cost and fair value results from unamortized fees, which are capitalized to the investment cost. The unfunded loan commitment may be subject to a commitment termination date that may expire prior to the maturity date stated.
