(b) Except as provided for in subsection (c) and subsection (d), a fiduciary shall allocate to principal any gain or loss realized upon the sale or maturity of any bond or obligation to pay money to the fiduciary, regardless of how such bond or other obligation was acquired.

(d) For bonds or other obligations that are acquired by a fiduciary subsequent to the time the principal was established and whose cost is greater than their par or maturity value, the fiduciary shall amortize periodically out of income the premium paid, and upon sale or maturity, shall allocate to principal any gain or loss realized thereon.
