In 1993, the Insurance Services Office (ISO) revised the language of the form 2010 endorsement utilized by the insurance industry to expressly restrict coverage for an additional insured to the "ongoing operations" of the named insured. This revised language effectively precludes application of the endorsement's coverage to completed operations losses. (Wielinski et al., Contractual Risk Transfer, supra, XI.C, p. 26.) One insurance commentator stated regarding the 1993 revisions of the standard additional insured endorsement forms: "The restriction of coverage in the two endorsements to only ongoing operations makes it clear that additional insureds will have no coverage under the named insured's policy for liability arising out of the products-completed operations exposure. . . . the effect of this change--restricting the coverage to ongoing operations--is, however, much more profound on [form 2010]. Previous editions of [that form] contained no completed operations exclusion and, thus, could be called on to cover an additional insured for liability arising out of the products-completed operations hazard." (Malecki, the Additional Insured Book (IRMI 3d ed. 1997) ch. 9, pp. 141-142.) Similarly, construction industry and underwriting spokespersons have echoed this assessment: "Completed Operations Coverage. Prior to the 1993 . . . revisions, the standard ISO additional insured endorsements provided the additional insured with coverage for liability arising out of 'your operations performed for' the additional insured, which included completed operations. More recent editions of these endorsements provide coverage only with respect to 'your ongoing operations,' which effectively eliminates coverage for completed operations." (Construction Risk Management (IRMI 1999) VI, p. VI.C.25.)
