因为GPB是公司所在地的货币，所以GBP的变动不影响公司operating expence?

问题如下：

Mark Crawley is an analyst at a London-based private equity firm and is reviewing the firm's file on Thames Air Plc (Thames), a company it provides financing for. Thames uses International Financial Reporting Standards (IFRS) in the preparation of its financial statements. Thames is a relatively new airline based in the United Kingdom specializing in flights and vacation packages to Mediterranean locations, primarily Spain. Thames sells most of its flights and vacation packages to British residents in British pounds (GBP) and considers the costs of local competitors' packages when determining its prices. Costs are incurred in multiple currencies:

•Wage costs are primarily in GBP.

•Typical of the industry, airline fuel and lease costs are normally priced in US dollars (USD).

•The landing fees paid at the vacation-area airports are in the local currency, primarily euros (EUR).

Crawley reviews the change in the exchange rate for the USD to GBP during 2015, shown in Exhibit 1, and wonders what the effect of this change was on Thames's operating income.

Which of the following statements about the effect of the change in the USD to GBP exchange rate during the year is most accurate? Operating income for Thames would:

选项：

A.

increase because of the positive effect on revenues.

B.

increase because of the positive effect on operating costs.

C.

decrease because of the negative effect on operating costs.

解释：

Thames incurs fuel and lease costs in USD. During the year, the USD has strengthened relative to the GBP (from GBP0.6400/USD to GBP0.6800/USD), thereby making purchases (costs) in USD more expensive for Thames and thus decreasing operating income.
