The maker of diggers and dozers direct exposure to the sector is equal to about $6.5 billion, or 12% of revenue, while its indirect exposure may be as much as 15% of revenues, analysts wrote in a note. That means almost 30% of its total revenue is facing pressure in 2015 and 2016.

The company said that “30% of its revenue is facing pressure”
That does not mean that all 30% of the revenue is at risk.
The 25% rise in the USD is a reduction of the ex-US topline (unless they hedge their exposure, which they probably do not).
