What is the primary role of a fund's custodian?

The primary role of a fund's custodian is to safeguard the mutual fund's assets and ensure proper handling of transactions. Custodians are responsible for holding and protecting the securities of the fund, which includes tasks such as settling transactions, collecting income from investments, and maintaining accurate records of the fund's holdings. They ensure that the assets are secure and properly accounted for, which is crucial for maintaining investor confidence and regulatory compliance.

While the other options describe important functions related to mutual funds, they do not capture the core responsibilities of a custodian. For instance, managing marketing and communications, setting investment strategies, or providing administrative services are typically handled by different parties or roles within the investment management ecosystem. The custodian's focus is specifically on the physical safety and proper management of the fund's assets.
