The quick ratio takes (cash + accounts receivable) / (current liabilities). Since all of these items are monetary assets and liabilities, they are all remeasured at the current exchange rate, resulting in no change to the ratio. The accounts receivable turnover ratio is calculated as (sales / accounts receivable). Note that the local currency (the U.S. dollar) is depreciating (it takes more $ to buy a pound). Since sales is remeasured at the average rate and accounts receivable is remeasured at the current rate, the depreciating currency means that the remeasured denominator will be smaller than the remeasured numerator, resulting in a larger ratio |
