Defined Benefit and Defined Contribution Recordkeeping

Investment Service Operations System

Corporate Audit Department (CAD)
Based on its periodic risk assessments of Company operations, CAD conducts internal audits of
MassMutual business operations and systems. The results of the audits are presented to MassMutual
management who are required to respond with action plans to remediate audit findings.

Information and Communication
MassMutual management consistently and regularly communicates the importance of following policies
and procedures as well as the importance of complying with the rules and regulations that govern our
operations. Management uses a variety of mechanisms to communicate this message including department
meetings and compliance newsletters. Additionally, MassMutual Corporate Policies and Procedures help
enforce the importance of open communication channels through Corporate Policies and Procedures
Manuals such as the Code of Conduct. Associates are encouraged and empowered to identify and raise
concerns and issues to management to facilitate appropriate and timely resolution. MassMutual employs a
number of tools to facilitate open communication such as the MassMutual Compliance and Ethics Reporting
Hotline. Additionally, the employee and manager performance evaluation program is designed to
encourage open and regular communication and information sharing.

MassMutual also encourages and maintains two way communications with its Plan Sponsor and participant
clients regarding the services that MassMutual provides including new and changed products, privacy and
security concerns and satisfaction with services offered and scope and availability of related SOC reports.

Other Considerations

The Company is subject to regulation and supervision by the Division of Insurance of the Commonwealth
of Massachusetts as well as other countries and states in which business is conducted. As such, the
Company is required to file periodic reports with and is subject to periodic examination by, the
Commonwealth of Massachusetts as well as other countries and states where business is conducted. The
Company’s most recent, completed examination by the Division of Insurance was for the year ended
December 31, 2014; an examination for the year ended December 31, 2019 was initiated but not completed
during the period. In addition, MassMutual is subject to regulation by the Department of Labor (DOL), the
Internal Revenue Service (IRS), the Securities and Exchange Commission (SEC), and the Financial
Industry Regulatory Authority (FINRA).
Changes in the Control Environment

As part of ongoing operations, MassMutual makes changes to its operations and various support group’s
roles and responsibilities to better align the business to service clients. No significant changes to the in-
scope control environment were introduced during the period.
