45 C.F.R. § 30.26 Cost of collecting claim.
Title 45 - Public Welfare
The Secretary may compromise a debt if the cost or deterrence value of collection do not justify the enforced collection of the full amount. The amount accepted in compromise in such cases may reflect an appropriate discount for the administrative and litigative costs of collection, taking into account the time which it will take to effect collection. Costs of collection may be a substantial factor in the settlement of small debts, but not normally in the settlement of large debts.
