October 27, 1986, referred to in subsec. (e)(1)(B), was in the original “the date of the enactment of this Act” which was translated as meaning the date of the enactment of Pub. L. 99–563, which enacted subsec. (e), to reflect the probable intent of Congress.
Subsec. (b)(1). Pub. L. 99–563, § 12(d)(1), substituted “liability insurance” for “product liability or completed operations liability insurance, and comprehensive general liability insurance which includes either of these coverages,”.
Subsec. (b)(2)(A). Pub. L. 99–563, § 12(d)(2), struck out “product liability or completed operations insurance, and comprehensive general” before “liability coverage”.
