Without the Secretary's prior written approval, you may provide Financing or a Commitment to an Enterprise only if the resulting amount of your aggregate outstanding Financings and Commitments to that Enterprise and its Affiliates does not exceed 10 percent of the sum of:
Your Regulatory Capital as of the date of the Financing or Commitment; plus
Any permitted Distribution(s) you made during the five years preceding the date of the Financing or Commitment which reduced your Regulatory Capital; plus
The total amount of Leverage provided to the Rural Business Investment Company by the Secretary since it was licensed under § 4290.390.
For the purposes of paragraph (a) of this section, you must measure each outstanding Financing at its original cost plus any amount of the Financing that was previously written off.
