(d) Distribution and power supply borrowers. If the aggregate of the investments, loans and guarantees of a distribution or power supply borrower exceeds 15 percent of the borrower's total utility plant as a result of the cumulative profits or margins, net of losses, earned on said transactions over the past 10 calendar years (i.e., the sum of all profits earned during the 10 years on all transactions—including interest earned on cash accounts, loans, and similar transactions—less the sum of all losses experienced on all transactions during the 10 years) then:
- (1) The borrower will not be in default of the RUS loan contract or RUS mortgage with respect to required approval of investments, loans and guarantees, provided that the borrower had not made additional net investments, loans or guarantees without approval after reaching the 15 percent level; and
- (2) At the request of the borrower, the Administrator in his or her sole discretion may decide to exclude up to the amount of net profits or margins earned on the borrower's investments, loans and guarantees during the past 10 calendar years, if the Administrator determines that such exclusion will not increase loan security risks. The borrower must provide documentation satisfactory to the Administrator as to the current status of its investments, loans and guarantees and the net profits earned during the past 10 years. Any exclusion approved by the Administrator may or may not reduce the level of investments, loans and guarantees to or below the 15 percent level. If such exclusion does not reduce the level to or below the 15 percent level, RUS will notify the borrower in writing that it must reduce or restructure its investments, loans and guarantees to a level of not more than 15 percent of total utility plant. If the borrower does not come within the 15 percent level within a reasonable period of time determined by the Administrator, which shall not exceed 12 months from the date the borrower was notified of the required action, then, upon written notice from RUS, the borrower shall be in default of its RUS loan contract and mortgage.
