ations to decommissioning trust agreements. Once a power reactor licensee has determined that it is within 5 years of permanent cessation of operations, it shall submit this report annually. Licensees of plants involved in mergers or acquisitions are also required to submit this report annually until the NRC has approved the merger or acquisition pursuant to 10 CFR 50.80 or 10 CFR 52.105. For such licensees, this report may be submitted as part of the license transfer application, provided that it contains the information described above. The NRC staff interprets this provision to require licensees to revert to a triennial reporting cycle upon completion of the merger or acquisition. 2.6.2 As long as the information described above is included in the report, no specific reporting format is required. The licensee should state with respect to any reporting item whether the item is not applicable, if appropriate. As part of the report, licensees do not need to submit a complete listing of all investments, although it is helpful to indicate broad categories of investments as a percent of the total trust portfolio (e.g., equities equal 20 percent of the total value of the trust, federal government bonds and notes equal 50 percent of the total value of the trust, etc.). In addition, each licensee should indicate the assurance mechanism being used as a source of revenues for the external sinking fund (e.g., traditional “cost-of-service” ratemaking, a non-bypassable charge, long-term contracts that the NRC has found to be acceptable pursuant to 10 CFR 50.75(e)(1)(v)).2 If the assumed real earnings rate on an external sinking fund exceeds 2 percent, each licensee should indicate the specific rate ruling or decision by its rate regulator that documents the earnings rate being used, as provided in 10 CFR 50.75(e)(1)(i) or (ii). If a licensee is using an assurance mechanism other than an external sinking fund, it should include adjustments to the assurance mechanisms (e.g.,
