13 CFR § 107.830 - Minimum duration/term of financing.
(a) General rule. The duration/term of all your Financings must be for a minimum period of one year.
(b) Restrictions on mandatory redemption of Equity Securities. If you have acquired Equity Securities, options or warrants on terms that include redemption by the Small Business, you must not require redemption by the Small Business within the first year of your acquisition except as permitted in § 107.850.
(c) Special rules for Loans and Debt Securities—(1) Term. The minimum term for Loans and Debt Securities starts with the first disbursement of the Financing.
(2) Prepayment. You must permit voluntary prepayment of Loans and Debt Securities by the Small Business. You must obtain SBA's prior written approval of any restrictions on the ability of the Small Business to prepay other than the imposition of a reasonable prepayment penalty under paragraph (c)(3) of this section. For purposes of evaluating prepayment restrictions under this section, requirements to apply prepayments pro rata among a group of lenders participating in such Financing that is pari passu in rights to payment will not be deemed to constitute a restriction on prepayments.
(3) Prepayment penalties. You may charge a reasonable prepayment penalty which must be agreed upon at the time of the Financing. If SBA determines that a prepayment penalty is unreasonable, you must refund the entire penalty to the Small Business. A prepayment penalty equal to 5 percent of the outstanding balance during the first year of any Financing, declining by one percentage point per year through the fifth year, is considered reasonable.
