Cal. Fin. Code § 5602

In addition to the minimum capital required, the commissioner may require that the consideration for the issuance of capital stock shall be sufficient to create a paid-in surplus in an amount satisfactory to the commissioner. The minimum capital and surplus may be used for the reserves required by law and for other purposes as may be permitted by the board of directors, provided that the par value or stated value of the stock subscribed shall be maintained as the permanent capital of the association, as required by Sections 5604 and 5605.
