ADC Arrangement Under the ADC Arrangement, the Company provided financing to the property developer for the acquisition, development, and construction of a retail shopping center. The Company also expected to participate in the residual profit resulting from the ultimate sale or other use of the property. Classification and accounting for the ADC Arrangement as a loan, an investment in real estate, or a joint venture was determined by the Company’s evaluation of the characteristics and the risks and rewards of the ADC Arrangement. Because the Company expected to receive more than 50% of the residual profit from the ADC Arrangement which had characteristics similar to a real estate investment, the costs of the real estate project were capitalized and interest was recognized in net investment income.
