12 CFR §160.31

1. (a)If a loan or other investment is authorized under more than one section of the HOLA, as amended, or this part, a Federal savings association may designate under which section the loan or investment has been made. Such a loan or investment may be apportioned among appropriate categories, and may be moved, in whole or part, from one category to another. A loan commitment shall be counted as an investment and included in total assets of a Federal savings association for purposes of calculating compliance with HOLA section 5(c)'s investment limitations only to the extent that funds have been advanced and not repaid pursuant to the commitment.
2. (b)Loans or portions of loans sold to a third party shall be included in the calculation of a percentage-of-assets or percentage-of-capital investment limitation only to the extent they are sold with recourse.
3. (c)A Federal savings association may make a loan secured by an assignment of loans to the extent that it could, under applicable law and regulations, make or purchase the underlying assigned loans.
