Three states and a handful of cities and counties have objected to a plan that would estimate the total value of legal claims against bankrupt opioid manufacturer Insys Therapeutics Inc.

Insys, which filed for Chapter 11 bankruptcy protection June 10, filed a motion to estimate the costs of about 1,000 lawsuits brought against the Phoenix-based company over the opioid crisis. The procedure would preserve funds and “fix aggregate amounts of particular categories of claims on an expedited basis,” according to the motion.
