The value of the accounting error was revised up from the $3 billion that was first reported by Reuters in May, the result of assigning a higher-than-warranted value on U.S. weaponry shipped to Ukraine.

Additional funding was uncovered as Pentagon officials researched the situation more thoroughly and clarified protocols for valuing equipment based on Financial Management Regulation and Department of Defense policy, Pentagon deputy press secretary Sabrina Singh said.

The $6.2 billion breaks down to $3.6 billion for fiscal year 2023 and $2.6 billion for fiscal year 2022, she said, adding that the errors did not impact the size of presidential drawdown authority or support for Ukraine.
