What effect is the sliding pound having on Britain's biggest companies?
In theory, the pound's 10 percent decline since the U.K. voted to leave the European Union on June 23 should make sales in other currencies more valuable when translated back into sterling. But borrowings in other currencies also become costlier to service, and imports become more expensive.
The reports present a mixed picture. This snapshot is based on companies publishing earnings on Thursday, one of the busiest days of the year for corporate results. It shows the effect of sterling's decline on profit growth.
Profit at Rolls Royce, for instance, was 4.2 percent higher than it would have been on constant 2015 exchange rates.

The pound was already down 3 percent since the start of the year by the time of the referendum date, so a weaker home currency has been part of the picture for U.K. companies all year.
