Does anyone have an example of "an actuarial statement of valuation showing compliance" with Section 401(a)(12) and the regs under 414(l) for Form 5310-A question 4(B)?

Does the statement need to be signed by anyone? If so, by whom?

Does the statement need to show specific numbers?

How does the statement "show" compliance?

Is it enough to simply have a statement that the action complies with 401(a)(12) and 414(l)?
