A proposed settlement (“Settlement”) has been reached in a lawsuit against HIMSS. The lawsuit claimed that class members paid fees for exhibition space, meeting space and/or sponsorships at the HIMSS 2020 Conference (“2020 Conference Fees”), that the HIMSS 2020 Conference was cancelled on or about March 5, 2020 due to the COVID-19 pandemic, and that class members suffered damages and are entitled to relief as a result. HIMSS denies these allegations. If approved by the Court, the Settlement resolves the case and provides benefits to Settlement Class Members that do not exclude themselves, including the option of a cash payment to Settlement Class Members that submit valid claims.

What are my options?

If you paid 2020 Conference Fees to HIMSS, you can (1) do nothing and receive the Credit-Only Option, (2) submit a Claim Form by June 11, 2021 to instead receive the Cash/Credit Option, (3) exclude yourself by May 27, 2021 or (4) object to the Settlement by May 27, 2021.

If you do not exclude yourself, and the Court approves the Settlement, you will be bound by the Court’s orders and judgments and will release your claims against HIMSS (including any that you have already initiated in any proceeding), even if you do not file a claim.
