The Pentagon has identified an additional $2 billion in accounting errors regarding military aid sent to Ukraine, raising the total miscalculated amount to $8.2 billion. This miscalculation was primarily due to the use of 'replacement value' instead of 'depreciated value' when assessing the worth of the equipment. The Government Accountability Office (GAO) reported that these inconsistencies stem from vague definitions in the Foreign Assistance Act and a lack of specific guidance for the Presidential Drawdown Authority. As a result, the Pentagon could allocate an additional $2 billion in arms to Ukraine, following the Biden administration's approval. The GAO has recommended that Congress clarify valuation definitions and has issued seven proposals for the Pentagon to improve its valuation processes. The Department of Defense has agreed with these recommendations and is working to implement changes.
