As of late September 1999, seventy-five Year 2000-related cases had already been filed. The most prevalent claims allege failure to provide fixes for noncompliant software. The remaining cases primarily are shareholder actions and recently filed insurance coverage actions.

To date, the anticipated flood of litigation has not yet materialized. Additionally, plaintiffs have had difficulty maintaining actions related to mass-produced software in the absence of allegations of unfair business practices. However, few decisions to date involve hardware and custom software products, which are the subject of many pending cases, and the narrow focus of decided cases makes extrapolation of decisions to other products difficult.
