We plan to begin the subject audit in April 2017. The Chief Financial Officers Act of 1990, as amended, requires this audit. In accordance with the Act, the DoD Office of Inspector General is the principal auditor for the Department of the Air Force Working Capital Fund Basic Financial Statements. Our objective is to determine whether the Air Force Working Capital Fund Basic Financial Statements as of September 30, 2017, and September 30, 2016, taken as a whole, were presented fairly, in all material respects, and in conformity with accounting principles generally accepted in the United States of America. In addition, we will determine whether these principles were consistently applied. We will review the Air Force Working Capital Fund Consolidated Balance Sheet as of September 30, 2017, and September 30, 2016, the related Consolidated Statement of Net Cost, Consolidated Statement of Changes in Net Position, Combined Statement of Budgetary Resources, and the related footnote disclosures. We will also review the Required Supplementary Information and Other Accompanying Information. In addition, we will review internal controls related to the reliability of financial reporting and compliance with laws and regulations that apply to these financial statements.
