Additionally, change any passwords for your Mizuno USA Inc. accounts and any other accounts where you might have reused the same credentials.

Mizuno USA Inc. had a legal obligation under various state and federal laws, including the Federal Trade Commission Act, to implement reasonable security measures to safeguard your personal information.
