To mitigate these risks, Schlumberger utilizes derivative instruments.

Schlumberger’s functional currency is primarily the US dollar, which is consistent with the oil and gas industry. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies. Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar—reported expenses will increase (decrease). </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Schlumberger is exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to provide a hedge against a portion of these cash flow risks. These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the <i>Consolidated Balance Sheet </i>and in <i>Accumulated Other Comprehensive Loss. </i>Amounts recorded in <i>Accumulated Other Comprehensive Loss</i> are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded directly to earnings. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">At March 31, 2011, Schlumberger recognized a cumulative net $10 million gain in <i>Equity </i>relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next twelve months. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Schlumberger is also exposed to changes in the fair value of assets and liabilities, including certain of its long-term debt, which are denominated in currencies other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to hedge this exposure as it relates to certain currencies. These contracts are accounted for as fair value hedges with the fair value of the contracts recorded on the <i>Consolidated Balance Sheet </i>and changes in the fair value recognized in the <i>Consolidated Statement of Income </i>along with the change in fair value of the hedged item. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">At March 31, 2011, contracts were outstanding for the US dollar equivalent of $7.5 billion in various foreign currencies. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><i>Commodity Price Risk</i> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Schlumberger is exposed to the impact of market fluctuations in the price of certain commodities, such as metals and fuel. Schlumberger utilizes forward contracts to manage a small percentage of the price risk associated with forecasted metal purchases. The objective of these contracts is to reduce the variability of cash flows associated with the forecasted purchase of those commodities. These contracts do not qualify for hedge accounting treatment and therefore, changes in the fair value of the forward contracts are recorded directly to earnings. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">At March 31, 2011, $27 million of commodity forward contracts were outstanding. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><i>Interest Rate Risk</i> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Schlumberger is subject to interest rate risk on its debt and its investment portfolio. Schlumberger maintains an interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its investment portfolio and occasionally interest rate swaps to mitigate the exposure to changes in interest rates. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">During the third quarter of 2009, Schlumberger entered into an interest rate swap for a notional amount of $450 million in order to hedge changes in the fair value of Schlumberger’s $450 million 3.00% Notes due 2013. Under the terms of this swap, Schlumberger receives interest at a fixed rate of 3.0% annually and pays interest quarterly at a floating rate of three-month LIBOR plus a spread of 0.765%. This interest rate swap is designated as a fair value hedge of the underlying debt. This derivative instrument is marked to market with gains and losses recognized currently in income to offset the respective gains and losses recognized on changes in the fair value of the hedged debt. This results in no net gain or loss being recognized in the <i>Consolidated Statement of Income</i>. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">At March 31, 2011, Schlumberger had fixed rate debt aggregating $5.5 billion and variable rate debt aggregating $3.1 billion, after taking into account the effects of the interest rate swaps. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt"><i>Short-term investments </i>and <i>Fixed income investments</i>, <i>held to maturity</i>, totaled $3.1 billion at March 31, 2011, and were comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds, and were substantially all denominated in US dollars.

Schlumberger is cooperating with the governmental authorities and is currently unable to predict the outcome of this matter. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">In 2009, Schlumberger learned that United States officials began a grand jury investigation and an associated regulatory inquiry, both related to certain Schlumberger operations in specified countries that are subject to United States trade and economic sanctions. Also in 2009, Smith received an administrative subpoena with respect to its historical business practices in certain countries that are subject to United States trade and economic sanctions. Schlumberger is cooperating with the governmental authorities and is currently unable to predict the outcome of these matters. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">On April 20, 2010, a fire and explosion occurred onboard the semisubmersible drilling rig <i>Deepwater Horizon</i>, owned by Transocean Ltd. and under contract to a subsidiary of BP plc. Pursuant to a contract between M-I SWACO and BP, M-I SWACO provided certain services under the direction of BP. A number of legal actions, certain of which name an M-I SWACO entity as a defendant, have been filed in connection with the <i>Deepwater Horizon </i>incident, and additional legal actions may be filed in the future. Based on information currently known, the amount of any potential loss attributable to M-I SWACO with respect to potential liabilities related to the incident would not be material to Schlumberger’s consolidated financial position. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Schlumberger and its subsidiaries are party to various other legal proceedings from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material loss is remote and, as such, that any liability that might ensue would not be material in relation to Schlumberger’s consolidated financial position. However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of these proceedings. </div> </div>
