B. Amount realized. The amount realized from the sale or other disposition of property shall be the sum of any money received plus the fair market value of property (other than money) received.

C. Recognition of gain or loss. In the case of a sale or exchange, the extent to which the gain or loss determined under this Section shall be recognized for the purpose of this Chapter, shall be determined under the provisions of R.S. 47:132 through 47:138.
