In a filing with U.S. financial regulators, Houston-based Smith named those two countries and Syria as places where the U.S. government imposed economic sanctions or other restrictions.
Smith said that, via non-U.S. affiliates, it earned about 1 percent of its $8.2 billion in 2009 revenue from the countries, and they were not "strategically significant" to its worldwide operations.
The company said separately that its restructuring last year, in response to a collapse in North American drilling activity, cost it $58.4 million. This was largely from shedding nearly 15 percent of its workforce, as Smith ended 2009 with 21,931 full-time employees.
While that was a deeper reduction than some larger rivals made, leading land-driller Nabors Industries Ltd revealed last week that it shed a third of its employees in 2009. (Reporting by Braden Reddall; editing by Gunna Dickson)
