Adventure IO generally supports payment amounts that are payable from or to Participants or Guides to the smallest unit supported by a given currency (i.e., U.S. cents, Euro cents or other supported currencies). Where Adventure IO’s third-party payment services provider does not support payments in the smaller unit supported by a given currency, Adventure IO may, in its sole discretion, round up or round down amounts that are payable from or to Participants or Guides to the nearest whole functional base unit in which the currency is denominated (i.e. to the nearest dollar, Euro or other supported currency); for example, Adventure IO may round up an amount of $101.50 to $102.00, and round down an amount of $101.49 to $101.00.
