The Company’s fourth quarter was primarily influenced by increased drilling activity in the North American market coupled with stable prices for the Company’s products and services, and by a significant increase in revenue per rig in Latin America and Africa for both M-I SWACO and the Smith Oilfield segments. The improved North American environment contributed to strong revenue growth in the Distribution segment, as well as in the PathFinder and cased-hole wireline service businesses. Although healthy revenue growth for M-I SWACO and Smith Technologies outside North America helped improve overall profitability, margin expansion was hampered by the current level of pricing in the U.S. market.
