A. With reference to insurance against loss or damage to property (except as provided in Section 1507 of this article) and with reference to all general casualty insurance, and surety insurance, every insurer shall maintain an unearned premium reserve on all policies in force.

B. The Insurance Commissioner may require that such reserves shall be equal to the unearned portions of the gross premiums in force after deducting reinsurance in solvent insurers as computed on each respective risk from the policy's date of issue. If the Insurance Commissioner does not so require, the portions of the gross premium in force, less reinsurance in solvent insurers to be held as a premium reserve, shall be computed according to the following table:

C. Unearned premium reserves on policies written for an intermediate period shall be calculated at the succeeding longer period or on a monthly pro rata basis.

D. In lieu of computation according to the foregoing table, all of such reserves may be computed, at the option of the insurer, on a monthly or more frequent pro rata basis.

E. After adopting a method for computing such reserve, an insurer shall not change methods without approval of the Insurance Commissioner.

F. This section does not apply to title insurance.
