The Office of Financial Operations (FMO), under the Assistant Secretary of the Navy, Financial Management and Comptroller (ASN, FM&C), acts on behalf of the DON and is responsible for financial and accounting matters. FMO leads financial programs and activities that are designed to improve the way the DON does business and support the warfighter.

As Department of Defense (DoD) directives and policies are set for financial efficiency, effectiveness, and transparency, FMO reports on financial data, as well as develops and manages accounting and finance related programs to help Budget Submitting Offices (BSOs), Commands, and other Shared Service Providers (SSP) comply with the DoD requirements and audit response.
