ADC Arrangement Under the ADC Arrangement, the Company provides financing to a property developer for the acquisition, development, and construction of a retail shopping center. The Company also expects 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 is determined by the Company’s evaluation of the characteristics and the risks and rewards of the ADC Arrangement. If the Company expects to receive more than 50% of the residual profit from the ADC Arrangement and it has characteristics similar to a real estate investment, the costs of the real estate project will be capitalized and interest will be recognized in net investment income.
