(a) General. The PBGC will defer payment, or agree to other arrangements for the satisfaction, of any portion of liability to the PBGC only when—

(b) Upon request. If the PBGC determines that such action is necessary to avoid the imposition of a severe hardship on persons that are or may become liable under section 4062, 4063, or 4064 of ERISA and that there is a reasonable possibility that persons so liable will be able to meet the terms prescribed and pay the entire liability, the PBGC, in its discretion and when so requested in accordance with paragraph (b)(2) of this section, may grant deferred payment or other terms for the satisfaction of such liability.

(c) Liability exceeding 30 percent of collective net worth. If the PBGC determines that section 4062(b) liability exceeds 30 percent of the collective net worth of persons subject to the liability, the PBGC will, after making a reasonable effort to reach agreement with such persons, prescribe commercially reasonable terms for payment of so much of the liability as exceeds 30 percent of the collective net worth of such persons. The terms prescribed by the PBGC for payment of that portion of the liability (including interest) will provide for deferral of 50 percent of any amount otherwise payable for any year if a person subject to such liability demonstrates to the satisfaction of the PBGC that no person subject to such liability has any individual pre-tax profits (within the meaning of section 4062(d)(2) of ERISA) for such person's last full fiscal year ending during that year.

(d) Interest. Interest on unpaid liability is calculated in accordance with § 4062.7(a).

(e) Security during period of deferred payment. As a condition to the granting of deferred payment terms, PBGC may, in its discretion, require that the liable person(s) provide PBGC with such security for its obligations as the PBGC deems adequate.
