Example. A public utility has outstanding 1,000 bonds which were issued before October 1, 1942, and each of which has a face value of $100. On or after October 1, 1942, each of such bonds is retired in exchange for 11/10 shares of preferred stock issued on or after October 1, 1942, and having a par value of $100 per share. Only 10/11 of the dividends paid on the preferred stock thus issued in exchange for the bonds will be considered as having been paid on stock which was issued before October 1, 1942. Likewise, if preferred stock which is issued on or after October 1, 1942, has no par value but a stated value of $50 per share and such stock is issued in a ratio of three shares to one share to refund or replace preferred stock having a par value of $100 per share, only two-thirds of the dividends paid on the new shares of stock will be considered as having been paid on stock which was issued before October 1, 1942.
