Asset management giant Vanguard has been fined more than $100 million to settle charges related to disclosures around target date investment funds, the Securities and Exchange Commission announced Friday.

The $106.41 million penalty will be paid out to hundreds of thousands of investors, whom investigators say Vanguard failed to adequately inform of a critical change to its retirement funds.

An investigation by the S.E.C. and several states found that the company had failed to notify investors of changes in the terms of some funds, leading to higher capital gains taxes.
