Insurance Code (usually included in commercial codals)
Section 243. The amount of any loss or damage for which an insurer may be liable, under any policy other than life insurance policy, shall be paid within thirty days after proof loss is received by the insurer and ascertainment of the loss or damage is made either by agreement between the insured and the insurer or by arbitration; but if such ascertainment is not had or made within sixty days after such receipt by the insurer of the proof of loss, then the loss or damage shall be paid within ninety days after such receipt. Refusal or failure to pay the loss or damage within the time prescribed herein will entitle the assured to collect interest on the proceeds of the policy for the duration of the delay at the rate of twice the ceiling prescribed by the Monetary Board, unless such failure or refusal to pay is based on the ground that the claim is fraudulent.
