(1) A reciprocal insurer may return to its subscribers any unused premiums, savings, or credits accruing to their accounts. Such distribution may not unfairly discriminate between classes of risks or policies, or between subscribers, but may vary as to classes of subscribers based on the experience of the classes.
(2) In addition to the option provided in subsection (1), a domestic reciprocal insurer may, upon the prior written approval of the office, pay to its subscribers a portion of unassigned funds of up to 10 percent of surplus, with distribution limited to 50 percent of net income from the previous calendar year. Such distribution may not unfairly discriminate between classes of risks or policies, or between subscribers, but may vary as to classes of subscribers based on the experience of the classes.
