The New York attorney general's office, as part of an ongoing case against Purdue Pharma and some members of the Sackler family, said in court filings on Friday it's discovered approximately $1 billion the family may have been trying to hide from parties suing them over the opioid crisis.

The Sackler family, which owns Purdue Pharma, used Swiss and other hidden bank accounts to transfer around $1 billion from the company to themselves, the New York attorney general’s office claimed Friday.

The family stands to lose billions after a litany of lawsuits claiming that their company marketed the painkiller OxyContin as nonaddictive despite knowing otherwise.

The transfers support allegations by New York and other states that the Sacklers have worked to shield their wealth in the face of mounting legal threats.

The New York Attorney General's Office has allegedly uncovered $1 billion in wire transfers by the Sackler family, which owns Purdue Pharma, which could suggest attempts to hide its wealth as it faces litigation over its role in the opioid crisis.

The transfers include some done through Swiss bank accounts, The New York Times reported.

State Attorney General Letitia James (D) reportedly issued subpoenas last month to 33 financial institutions and investment advisers in an attempt to fully discover the family's wealth.

Purdue Pharma has tentatively reached the first "global" settlement in the nationwide opioids lawsuit, the New York Times and AP report. The plaintiffs later confirmed this to Axios.

The big picture: The deal would reportedly result in the maker of OxyContin entering bankruptcy and the Sackler family owners paying $3 billion over 7 years, among other terms. Some states still aren't on board with the proposal and may pursue Purdue and the Sacklers further, NYT reports. But the first major deal appears imminent ahead of the scheduled October trial.
