When any domestic company becomes insolvent, or is unable to pay in full its liabilities as set forth in sections ten, eleven and twelve, claims for unpaid losses under its policies, other than life or endowment policies or annuity or pure endowment contracts, shall, in the distribution of its assets, whether liquidation is effected by a receiver or otherwise, be deemed and treated as preferred over claims for return premiums on cancelled or unexpired policies. Nothing in this section shall impair the obligation now or hereafter imposed by law upon the officers of a mutual company, other than a life company, to make assessments on its members to pay its incurred losses and expenses.
