19 C.F.R. § 351.505
(iii) Exception for uncreditworthy companies. If the Secretary finds that a firm that received a government-provided long-term loan was uncreditworthy, as defined in paragraph (a)(4) of this section, the Secretary normally will calculate the interest rate to be used in making the comparison called for by paragraph (a)(1) of this section according to the following formula:
ib = [(1 − qn)(1 + if) n / (1 − pn)]1/n − 1,
where: n = the term of the loan; ib = the benchmark interest rate for uncreditworthy companies; if = the long-term interest rate that would be paid by a creditworthy company; pn = the probability of default by an uncreditworthy company within n years; and qn = the probability of default by a creditworthy company within n years.
“Default” means any missed or delayed payment of interest and/or principal, bankruptcy, receivership, or distressed exchange. For values of pn, the Secretary will normally rely on the average cumulative default rates reported for the Caa to C-rated category of companies in Moody's study of historical default rates of corporate bond issuers. For values of qn, the Secretary will normally rely on the average cumulative default rates reported for the Aaa to Baa-rated categories of companies in Moody's study of historical default rates of corporate bond issuers.
(4) Uncreditworthiness—(i) In general. The Secretary will consider a firm to be uncreditworthy if the Secretary determines that, based on information available at the time of the government-provided loan, the firm could not have obtained long-term loans from conventional commercial sources. The Secretary will determine uncreditworthiness on a case-by-case basis, and may, in appropriate circumstances, focus its creditworthiness analysis on the project being financed rather than the company as a whole. In making the creditworthiness determination, the Secretary may examine, among other factors, the following:
(ii) Government-owned banks. The Secretary will not investigate a loan provided by a government-owned bank absent a specific allegation that is supported by information reasonably available to petitioners indicating that:
(ii) Calculation of annual benefit. With respect to the benefit calculated under paragraph (c)(3)(i) of this section, the Secretary will determine the portion of that benefit to be assigned to a particular year by using the formula set forth in § 351.524(d)(1) and the following parameters:
Ak = the amount countervailed in year k, y = the present value of the benefit (see paragraph (c)(3)(i) of this section), n = the number of years in the life of the loan, d = the interest rate on the comparison loan selected under paragraph (a) of this section, and k = the year of allocation, where the year that repayment would begin on the comparable commercial loan = 1.
