5 C.F.R. § 1639.53
A debtor who admits liability but elects not to have the debt collected by administrative offset will be afforded an opportunity to negotiate a written agreement for repaying the debt. If the financial condition of the debtor does not support the ability to pay in one lump sum, the Board may consider reasonable installments. No installment arrangement will be considered unless the debtor submits a financial statement, executed under penalty of perjury, reflecting the debtor's assets, liabilities, income, and expenses. The financial statement must be submitted within 10 business days of the Board's request for the statement. At the Board's option, a confess-judgment note or bond of indemnity with surety may be required for installment agreements. Notwithstanding the provisions of this section, any reduction or compromise of a claim will be governed by 31 U.S.C. 3711 .
