What is cross currency headwinds?

I am hearing this term a lot these days in news related to IT and Pharma companies.

What is this?

Can anyone explain???

IT and Pharma companies have a significant revenue from export of services and goods. This means they receive money (revenues) in terms of foreign currency ($ mainly). Cross Currency head winds is a term used to indicate a possible loss in revenue due to volatility in currency cross such as USD-INR, INR-GBP , INR-JPY etc.
