§ 4043.32 Transfer of benefit liabilities.
(a) Reportable event. A reportable event occurs for a plan when—
(1) The plan makes a transfer of benefit liabilities to a person, or to a plan or plans maintained by a person or persons, that are not members of the transferor plan's controlled group; and
(2) The amount of benefit liabilities transferred, in conjunction with other benefit liabilities transferred during the 12-month period ending on the date of the transfer, is 3 percent or more of the plan's total benefit liabilities. Both the benefit liabilities transferred and the plan's total benefit liabilities are to be valued as of any one date in the plan year in which the transfer occurs, using actuarial assumptions that comply with section 414(l) of the Code.
