①If a bond-issuing company redeems a bond for which a bond certificate is issued before it matures, if a coupon attached to the bond is missing, the bond-issuing company must deduct the amount of the claim for interest on the bond indicated on coupon from the redemption amount;provided, however, that this does not apply if relevant claim has fallen due.

②The possessor of the coupon in the preceding paragraph may demand at any time that the bond-issuing company pay the amount that must be deducted under the provisions of that paragraph in exchange for the coupon.
