Whenever an association organized under this article with preferred capital stock desires to purchase the stock of any person, firm, corporation, or association or any property or property interest thereof, it may make the purchase, in whole or in part, by exchanging for the acquired interest shares of its preferred capital stock, in an amount which at par value would equal the fair market value of the stock or interest so purchased, as determined by the board of directors. The transfer to the association of the stock or interest so purchased shall be equivalent to payment in cash for the shares of stock issued.
