Mass. Gen. Laws ch. 176G, § 28
(b) Every health maintenance organization subject to registration shall file the registration statement on a form prescribed by the commissioner, which shall contain the following current information:
(l) Transactions within a health maintenance organization holding company system to which a health maintenance organization subject to registration is a party shall be subject to the standards specified by the commissioner by rule, regulation or order, including the following:
(m) The following transactions involving a domestic health maintenance organization and any person in its holding company system may not be entered into unless the health maintenance organization has notified the commissioner in writing of its intention to enter into any such transaction at least 30 days prior thereto, or such shorter period as the commissioner may permit, and the commissioner has not disapproved it within such period.
(5) any transactions, specified by regulation, which the commissioner determines may adversely affect the interests of the health maintenance organization's policyholders or enrolled members.
Notification shall be provided to the commissioner for transactions in clauses (1) to (5), inclusive, which increase or decrease the health maintenance organization's net worth as of the next preceding December 31 by 5 per cent or more. The notification shall accompany the next quarterly financial statement filing. Nothing in this section shall authorize or permit any transactions which would otherwise be contrary to law, or to relieve any health maintenance organization or other person of any obligation arising under chapter 180.
(q) No domestic health maintenance organization shall pay any extraordinary dividend or make any other extraordinary distributions to its shareholders, members or officers until 30 days after the commissioner receives notice of the declaration thereof and has not within such period disapproved such payment, or the commissioner approves such payment. For purposes of this section, an extraordinary dividend or distribution includes any dividend or distribution of cash or other property, whose fair market value together with other dividends or distributions made within the preceding 12 months exceeds the greater of (i) 10 per cent of such health maintenance organization's net worth as of the next preceding December 31, or (ii) the net income of the health maintenance organization for the 12–month period ending the next preceding December 31.
Notwithstanding any other general law to the contrary, a health maintenance organization may declare an extraordinary dividend or distribution which is conditional on the commissioner's approval thereof, and such a declaration shall confer no rights upon any person until the commissioner has approved the payment of such dividend or distribution or the commissioner has not disapproved such payment within the 30 day period set by this subsection.
