(a) While class 1 public securities are outstanding, the association must deposit net premium and other revenue in the class 1 public security trust fund at periods and in amounts as required by the class 1 public security agreements to fund the class 1 payment obligation. As required by Insurance Code §2210.609(c), the association must deposit association surcharges collected under Insurance Code §2210.612 in the class 1 public security trust fund.     
      (b) Without limiting other options, the class 1 public security agreements may include an operating reserve fund. If the class 1 public security trust fund does not contain sufficient money to pay debt service on the class 1 public securities, administrative expenses on the class 1 public securities, or other class 1 public security obligations, the association must transfer sufficient money from any operating reserve fund or other association-held funds to the class 1 public security trust fund to make the payment.     
      (c) The association may not directly or indirectly use, borrow, or in any manner pledge or encumber association surcharges collected or to be collected, except for the payment of class 1 public security obligations and as otherwise authorized in this title.     
      (d) The trust company must deposit any net investment income earned on net premium and other revenue and on the association surcharges into the class 1 public security trust fund while these amounts are on deposit.     
      (e) Following the issuance of public securities, net premium may be pledged for the payment of class 2 and class 3 payment obligations. Net premium earned in one catastrophe year may be pledged for the repayment of public securities issued in prior catastrophe years.
