Congressional Budget Office Cost Estimate: S. 3591, United States-Ecuador Partnership Act of 2022 [open pdf - 165KB]
From the Document: "S. 3591 would authorize the Administration to transfer up to two U.S. Coast Guard cutters to Ecuador. Section 9 would require the Administration to assess Ecuador's capacity to maintain cutters that the Coast Guard no longer requires and would authorize the transfer of up to two boats to Ecuador. Excess items are often sold at a discount or provided at no cost to the recipient. [...] CBO [Congressional Budget Office] estimates that satisfying that requirement would cost less than $500,000 over the 2022-2026 period. Such spending would be subject to the availability of appropriated funds."
