The company listed as much as $10 billion in assets, including $1.2 billion in cash, and $1 billion in debts in its Chapter 11 filing. Purdue officials said Sunday the costs of dealing with waves of opioid suits made a bankruptcy inevitable, and the company projected it will spend about $263 million on legal and related professional costs in 2019.

The Sacklers guaranteed they'll pay a minimum of $3 billion toward the settlement, with most of the sum generated by selling Purdue's U.K.-based drugmaker Mundipharma.

The family has rejected calls by some state attorneys general to boost their guarantee to $4.5 billion. Of the 48 states that have court actions pending against the company in some forum, half have refused to sign on to the settlement. States that aren't satisfied with Purdue's proposal will get a chance to voice their opposition before a bankruptcy judge approves the accord.

The plan calls for Purdue officials to set up a trust responsible for operating the company, which would generate money that governments could use to bolster drug treatment and policing budgets. That entity, run by trustees appointed by a bankruptcy judge, also will oversee payouts to state and local governments that sued.

"This unique framework for a comprehensive resolution will dedicate all the assets and resources of Purdue for the benefit of the American public," Steven Miller, the drugmaker's board chairman, said in an emailed statement.

To make its plan work, the company said it will soon ask the judge overseeing the case to halt lawsuits brought by local and state governments that are not part of the current deal. Typically, such government regulatory actions are allowed to continue while a company is in bankruptcy, while private lawsuits are halted.

Who gets what

The court that will oversee Purdue's case has the thorny task of trying to figure out how to apportion monies generated by the plan among thousands of states, cities and counties seeking reimbursement for tax dollars spent on the crisis.

That allocation "will be one of the main tasks in the case," Miller said Sunday. Lawyers for cities and counties have created computer programs that calculate how much a municipality could get under the deal based on the amount of opioids circulated in the area.

U.S. Bankruptcy Judge Robert Drain has been assigned to oversee Purdue's Chapter 11 case. His White Plains court is about a 20-minute drive from Purdue's Stamford, Connecticut headquarters.

A veteran bankruptcy judge, Drain has handled similar high-profile filings, including that of Sears Holding Corp., which was sold to hedge fund manager Eddie Lampert's ESL Investments Inc. He also oversaw the sale of some of Delphi Corp.'s assets in 2009 after the auto-parts maker and ex-General Motors Co. spinoff sought protection from creditors.

Bigger bite

The Sackler family said it backed the proposed settlement in hopes of finding a way to provide "critical resources" to address an epidemic that some attorneys general have accused them of spawning.

"This process will bring the thousands of claims into a single, efficient forum where the settlement can be finalized, reviewed by the bankruptcy court to ensure it is fair and just and then implemented," the family said in an emailed statement.

Opponents argue Purdue's plan isn't enough of a reckoning for the Sacklers, who made billions from the over-prescribing of OxyContin that was spurred by the company's allegedly illegal marketing. It also won't provide enough reimbursement for hundreds of thousands of overdose deaths and addiction damage inflicted on millions of U.S. families, opponents say.

"Irrespective of Purdue's actions or evasions, we will continue to pursue justice on behalf of those harmed by the Sacklers' greed, callousness, and fraud," Delaware Attorney General Kathy Jennings said in an emailed statement.

The Sacklers and Purdue officials had sought to persuade 35 attorneys general to back the current settlement proposal. That super-majority would have held more sway in bankruptcy court when it came time to win final approval of the deal. As of Sunday, the company had lined up as many as 29 U.S. states and territories, according to Purdue's news release.

Purdue planned to file for protection from creditors by the end of September to avoid facing a Cleveland jury that's scheduled to hear evidence starting next month in the first federal trial over the opioid epidemic.

Public nuisance

A host of other opioid makers, such as Johnson & Johnson, and drug distributors like McKesson Corp., will face claims they created a public nuisance across the U.S. with their mishandling of the medicines.

States and municipalities contend drugmakers, distributors and pharmacy chains conducted illegal marketing campaigns pushing the painkillers, failed to adequately oversee orders and ignored red flags about unusually frequent retail sales.

In March, Purdue settled claims brought by the state of Oklahoma for $270 million, and another defendant, Teva Pharmaceutical Industries Ltd., also reached an $85 million deal to avoid trial. J&J, which refused to settle, was ordered to pay $572 million for creating a public nuisance in the state with its over-promotion of its opioid pain medicines.

The case is Purdue Pharma LP 19-23649, U.S. Bankruptcy Court for the Southern District of New York (White Plains).
