A Midwestern state has become the latest to encourage funeral insurers to stick with older, more conservative life expectancy tables.

Wisconsin has been permitting life insurers to use the 2001 Commissioners’ Standard Ordinary mortality table until Jan. 1, 2009, and requiring them to shift to the table, from the 1980 CSO mortality table, Jan. 1, 2009.

Wisconsin now will permit funeral insurers to continue using the 1980 CSO table, and it plans to develop a formal rule on the topic, Wisconsin Insurance Commissioner Sean Dilweg writes in a bulletin.

Regulators in Iowa and Michigan also have issued bulletins on the topic, noting that some question whether the life expectancies of holders of funeral insurance policies have increased as much as the 2001 CSO mortality table shows overall U.S. life expectancies have increased.
