Cal. CORP § 409

(a) Shares may be issued:

(1) For such consideration as is determined from time to time by the board, or by the shareholders if the articles so provide, consisting of any or all of the following: money paid; labor done; services actually rendered to the corporation or for its benefit or in its formation or reorganization; debts or securities canceled; and tangible or intangible property actually received either by the issuing corporation or by a wholly owned subsidiary; but neither promissory notes of the purchaser (unless adequately secured by collateral other than the shares acquired or unless permitted by Section 408) nor future services shall constitute payment or part payment for shares of the corporation; or

(2) As a share dividend or upon a stock split, reverse stock split, reclassification of outstanding shares into shares of another class, conversion of outstanding shares into shares of another class, exchange of outstanding shares for shares of another class or other change affecting outstanding shares.

(b) Except as provided in subdivision (d), shares issued as provided in this section or Section 408 shall be declared and taken to be fully paid stock and not liable to any further call nor shall the holder thereof be liable for any further payments under the provisions of this division. In the absence of fraud in the transaction, the judgment of the directors as to the value of the consideration for shares shall be conclusive.

(c) If the articles reserve to the shareholders the right to determine the consideration for the issue of any shares, such determination shall be made by approval of the outstanding shares (Section 152).

(d) A corporation may issue the whole or any part of its shares as partly paid and subject to call for the remainder of the consideration to be paid therefor. On the certificate issued to represent any such partly paid shares or, for uncertificated securities, on the initial transaction statement for such partly paid shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated. Upon the declaration of any dividend on fully paid shares, the corporation shall declare a dividend upon partly paid shares of the same class, but only upon the basis of the percentage of the consideration actually paid thereon.

(e) The board shall state by resolution its determination of the fair value to the corporation in monetary terms of any consideration other than money for which shares are issued. This subdivision does not affect the accounting treatment of any transaction, which shall be in conformity with generally accepted accounting principles.
