McKinsey Tribal Opioid Settlement

A nationwide settlement has been reached to resolve all Opioids litigation brought by federally recognized Tribes against McKinsey & Company, Inc. This settlement will provide substantial funds to participating Tribes for abatement of the opioid epidemic in Indian country.

The settlement went into effect in December 2023 and settlement funds will be distributed to Tribes in January 2024. Here are the basic details of the settlement:

  • McKinsey is paying $39,500,000 to participating federally recognized Tribes in a single payment.
  • The settlement is open to all 574 federally recognized Tribes, whether or not a Tribe has filed litigation against McKinsey, just as is the case with earlier nationwide tribal opioid settlements.
  • Settlement funds will be allocated among Tribes using the inter-tribal plan of allocation approved and adopted in the related Purdue (Opioid) Bankruptcy. This is the same allocation used to allocate most of the earlier nationwide tribal opioid settlements.
  • A total of 15% of the settlement funds will be set aside to pay attorney fees. The balance of 85% of the funds will be paid to participating Tribes. This is the same division of funds used in most of the earlier nationwide tribal opioid settlements.
  • As with all the earlier nationwide tribal opioid settlements, the settlement funds must be used for abatement of the opioid epidemic in tribal communities. “Abatement” uses are specified in a broadly defined list of approved programs, activities and services, with special deference for tribal governments to decide which culturally appropriate or traditional healing practices are best suited to their communities. The approved abatement uses are attached as an Exhibit to the Tribes-McKinsey Settlement Agreement. Again, this is the same list used in all of the earlier settlements.
  • In order to participate, a Tribe must sign and submit a Tribal Participation Form through a secure portal that can be accessed through this website.
  • The deadline to participate in the settlement is December 28, 2024. After that date, unclaimed settlement funds will be reallocated to all participating tribes of record on that date.
