[1] In March 2018, the Company acquired technology, talent and cross-border logistics infrastructure that operated a marketplace and casillero business. Investments in the technology, talent and infrastructure to expand our omni-channel capabilities, together with the operating results from the marketplace and casillero business, negatively impacted Net income attributable to PriceSmart, Inc. by $2.9 million for the quarter and $11.0 million for the nine months ended May 31, 2019. Management considers this business to be part of its United States operations.

[2] Translation adjustments arising in translating the financial statements of a foreign entity have no effect on the income taxes of that foreign entity. They may, however, affect: (a) the amount, measured in the parent entity's reporting currency, of withholding taxes assessed on dividends paid to the parent entity and (b) the amount of taxes assessed on the parent entity by the government of its country. The Company has determined that the reinvestment of earnings of its foreign subsidiaries are indefinite because of the long-term nature of the Company's foreign investment plans. Therefore, deferred taxes are not provided for on translation adjustments related to non-remitted earnings of the Company's foreign subsidiaries.
