Establish and maintain a formal year-end closing calendar with internal milestones and deadlines aligned to the FAC submission due date. Document year-end closing procedures (including required tasks, timelines, and supporting documentation). Assign clear responsibilities for closing tasks and for preparation, review, and submission of the Single Audit reporting package and data collection form. Monitor progress through periodic status updates and management review to ensure timely completion of the year-end close and timely submission to the Federal Audit Clearinghouse (FAC).
