(1) All bonds registered in the name of that person alone;

(2) All bonds registered in the name of the representative of the estate of that person; and

(3) All bonds registered in the name of that person as first-named coowner.

(c) Bonds excluded from computation. In computing the purchases for each person, the following are excluded:

(1) Bonds on which that person is named beneficiary;

(2) Bonds to which that person has become entitled—

(i) Under § 353.70 as surviving beneficiary upon the death of the registered owner;

(ii) As an heir or a legatee of the deceased owner;

(iii) By virtue of the termination of a trust or the happening of a similar event;

(3) Bonds issued in an authorized exchange or reinvestment; and

(4) Bonds that are purchased and redeemed within the same calendar year.
