The amounts due from Sonatide are denominated in U.S. dollars; however, the underlying third-party customer payments to Sonatide were satisfied, in part, in Angolan kwanzas. We and Sonangol, our partner in Sonatide, have had discussions regarding how the net losses from the devaluation of certain Angolan kwanza denominated accounts should be shared. In late 2019, we were informed that, as part of a broad privatization program, Sonangal intends to seek to divest itself from the Sonatide joint venture.

After offsetting the amounts due to Sonatide, the net amount due from Sonatide at March 31, 2020 was approximately $64.2 million. Sonatide had approximately $45.6 million of cash on hand (approximately $3.2 million denominated in Angolan kwanzas) at March 31, 2020 plus approximately $18.9 million of net trade accounts receivable to satisfy the net due from Sonatide. Given prior discussions with our partner regarding how the net losses from the devaluation of certain Angolan kwanza denominated accounts should be shared, we continue to evaluate our net amount due from Sonatide balance for potential impairment based in part on available liquidity held by Sonatide.

Amounts due to Sonatide represent commissions payable and other costs paid by Sonatide on our behalf.
