In general. The actuarial report described in this section must be filed on behalf on a defined benefit plan to which the minimum funding standards of section 412 apply. The actuarial report must be filed by the plan administrator (within the meaning of section 414(g)) on Schedule B as an attachment to the annual Return/Report of Employee Benefit Plan (Form 5500 series). The instructions accompanying the Form 5500 series prescribe the place and date for filing Schedule B.

Plan years for which report required. In the case of a plan in existence on January 1, 1974, Schedule B must be filed for the first plan year beginning after December 31, 1975, for which the minimum funding standards apply to the plan, and for each plan year thereafter for which the Schedule must be filed under the instructions accompanying the Schedule and the Form 5500 series. In the case of a plan not in existence on January 1, 1974, Schedule B must be filed for the first plan year beginning after September 2, 1974, for which the minimum funding standards apply to the plan, and for each plan year thereafter for which the Schedule must be filed under the instructions accompanying the Schedule and the Form 5500 series. For rules relating to when a plan is considered to be in existence, see § 1.410(a)-2(c). For purposes of this section, “plan year” means the plan year as determined for purposes of the minimum funding standards.

Contents of report. The actuarial report of a plan filed on Schedule B must contain—

The date of the actuarial valuation applicable to the plan year for which the report is filed (see section 412(c)(9) for rules relating to the frequency with which an actuarial valuation of the plan is required to be made),

A statement that the report is based in part on information provided by another person, that the actuary believes such information is or may be inaccurate or incomplete, but that the inaccuracies or omissions are not material, the inaccuracies or omissions are not so numerous or flagrant as to suggest that there may be material inaccuracies, and that therefore the actuarial report is substantially accurate and complete and fairly discloses the actuarial position of the plan,
