Each contract seller shall file with the commissioner a report, on a calendar year basis, on a form provided by the commissioner. In the report, each contract seller that is required to deposit funds with a trustee shall state the name of each trustee where trust funds are on deposit and the amount remaining on deposit in the trust fund on December 31. Any contract seller that has voluntarily or involuntarily discontinued the sale of preneed contracts need not obtain a renewal of its license but shall continue to make annual reports to the commissioner until all the contracts have been fully performed.
