Share Repurchases
On April 17, 2008, the Schlumberger Board of Directors approved an $8 billion share repurchase program for
Schlumberger common stock, to be acquired in the open market before December 31, 2011. On July 21, 2011, the Board
of Directors approved an extension of this repurchase program to December 31, 2013.
Schlumberger did not repurchase any common stock during the three months ended December 31, 2012. The
maximum value of shares that may be purchased under this program as of December 31, 2012 was $879 million.
In connection with the exercise of stock options under Schlumberger’s incentive compensation plans, Schlumberger
routinely receives shares of its common stock from optionholders in consideration of the exercise price of the stock
options. Schlumberger does not view these transactions as requiring disclosure under this Item 5 as the number of
shares of Schlumberger common stock received from optionholders is not material.
Unregistered Sales of Equity Securities
As discussed in Note 13 of the
Consolidated Financial Statements
, Schlumberger maintains a Discounted Stock
Purchase Plan (the “DSPP”), which was established in 1988. The DSPP provides for two purchase periods each
calendar year: January 1 to June 30 and July 1 to December 31. Schlumberger filed registration statements with the
SEC to register the shares initially available for purchase under the DSPP as well as to register additional shares that
were approved by Schlumberger stockholders in 2005. In 2010, Schlumberger stockholders approved an amendment to
the DSPP that, among other things, increased the number of shares available for purchase under the DSPP by
10,000,000 shares. In December 2012, Schlumberger discovered that it had inadvertently failed to file a registration
statement with the SEC to register the additional DSPP shares approved in 2010. In December 2012, Schlumberger
registered the sale of the shares that remain available for purchase under the DSPP. Prior to such registration,
however, some of the shares Schlumberger sold under the DSPP were unregistered. With respect to the six-month
