Sec. 13. The department may authorize the credit union resulting from a charter conversion under this chapter to do the following:
(1) Wind up any activities that the mutual savings bank legally engaged in at the effective time of the charter conversion but that otherwise are not permitted to credit unions.
(2) Retain for a transitional period any assets that the mutual savings bank legally held at the effective time of the charter conversion that otherwise may not be held by credit unions.
The terms and conditions of the winding up of activities under subdivision (1) and the retention of assets under subdivision (2) are subject to the discretion of the department. However, the transitional period during which activities may be carried out under subdivision (1) or assets may be retained under subdivision (2) may not exceed ten (10) years after the effective time of the charter conversion.
