(1) Every company authorized to transact in this State any of the kinds of business described in Class 3 of Section 4 shall, at all times, maintain reserves in an amount estimated in the aggregate to provide for the payment of all losses and claims incurred, whether reported or unreported, which are unpaid and for which such company may be liable, and to provide for the expenses of adjustment or settlement of such losses and claims. For the purpose of such reserves, the company shall keep a complete and itemized record showing all losses and claims on which it has received notice, including all notices received by it of the occurrence of any event which may result in a loss. Such record shall be opened in chronological receipt order, with each notice of loss or claim identified by appropriate number or coding.
     (2) Whenever the loss and loss expense experience of such company shows the reserves, calculated in accordance with the foregoing provisions, to be inadequate, the Director may require such company to maintain additional reserves.
