In the section, the word “obligation” is substituted for “security” in the defined term for consistency in the chapter and the revised title and to eliminate using the word “security” in 2 different ways in the same section.

In subsection (b), the words “Under such regulations as he may deem necessary for the administration of this section” are omitted as unnecessary because of section 321(b) of the revised title.

In subsection (c)(1), the words “whether before, at, or after maturity” and “in effect” are omitted as surplus.
