As part of continued efforts to improve how you access and use your Thermo Fisher Scientific benefits, the service provider for our Health Savings Account (HSA), Flexible Spending Accounts (FSA) and Commuter Benefits will transition to Fidelity Investments® effective January 1, 2025.

You could lose money by investing in a money market fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Fidelity Investments and its affiliates, the fund’s sponsor, are not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.

Fidelity’s government and U.S. Treasury money market funds will not impose a fee upon the sale of your shares.
