When a mutual insurance company is not possessed of cash funds above its reserve sufficient for the payment of insured losses and expenses, it must make an assessment for the amount needed to pay such losses and expenses upon its members liable to assessment therefor in proportion to their several liabilities. The company shall cause to be recorded in a book kept for that purpose the order for the assessment, together with a statement which must set forth the condition of the company at the date of the order, the amount of its cash assets and deposits, notes, or other contingent funds liable to the assessment, the amount the assessment calls for, and the particular losses or liabilities it is made to provide for. This record must be made and signed by the directors who voted for the order before any part of the assessment is collected, and any person liable to the assessment may inspect and take a copy of the same. When, by reason of depreciation or loss of its funds or otherwise, the cash assets of such company, after providing for its other debts, are less than the required premium reserve upon its policies, it must make good the deficiency by assessment in the manner above provided. If the directors are of the opinion that the company is liable to become insolvent they may, instead of such assessment, make two assessments, the first determining what each policyholder must equitably pay or receive in case of withdrawal from the company and having his policy canceled; the second, what further sum each must pay in order to reinsure the unexpired term of his policy at the same rate as the whole was insured at first. Each policyholder must pay or receive according to the first assessment, and his policy shall be cancelled unless he pays the sum further determined by the second assessment, in which case his policy continues in force; but in neither case may a policyholder receive or have credited to him more than he would have received on having his policy canceled by a vote of the directors under the bylaws.
