(a)Amounts primarily represent currency transaction gains and losses on contingent consideration payable related to G4S business acquisitions.

(b)Certain of our Latin American subsidiaries incur non-income taxes related to the billing of intercompany charges. These intercompany charges do not impact the Latin America segment results and are eliminated in our consolidation.

(c)State government tax incurred by our subsidiaries in Argentina on financial income generated by investments in mutual funds and other financial instruments.

(d)In 2023, the loss is primarily related to the impact of highly inflationary accounting on investments in marketable securities held by Argentina. In 2021, the gain was related to the market value increase of an investment in MoneyGram International, Inc. The investment was sold in 2021 and the gain was fully realized.

(e)Adjustment to indemnification asset related to business operations acquired from G4S. This adjustment was recognized outside of the measurement period for the related business operations acquired from G4S.
