Part II, Item 7 The following table summarizes the activity under these share repurchase programs during 2008, 2007 and 2006:
## Table 0 ##
Given the current credit and economic environment, Schlumberger anticipates that the total dollar amount of stock repurchases in 2009 may be significantly less than the $1.8 billion spent during 2008.
This anticipated reduction will serve to increase Schlumberger’s financial flexibility during these uncertain times.
Stock buy-back activity during 2009 will continue to be targeted to offset any dilution caused by the Schlumberger stock-based compensation programs.  ?
Cash flow provided by operations was $6.9 billion in 2008, $6.3 billion in 2007 and $4.7 billion in 2006.
These improvements were driven by the revenue and net income increases experienced in 2008 and 2007 offset by required investments in working capital.  ?
During 2008, 2007 and 2006, Schlumberger announced that its Board of Directors had approved increases in the quarterly dividend of 20%, 40% and 19%, respectively.
Total dividends paid during 2008, 2007 and 2006 were $964 million, $771 million and $568 million, respectively.  ?
Capital expenditures were $3.7 billion in 2008, $2.9 billion in 2007 and $2.5 billion in 2006.
These increases were a result of the increased activity levels experienced in recent years.
Capital expenditures are expected to approach $3.0 billion in 2009, including $385 million relating to the construction of seismic vessels.  ?
During 2008, 2007 and 2006 Schlumberger made $290 million, $250 million and $251 million, respectively, of contributions to its defined benefit pension plans.
The US qualified pension plan was 71% funded at December 31, 2008 based on the projected benefit obligation.
This compares to 109% funded at December 31, 2007.
Outside of the US, Schlumberger’s International Staff Pension Plan, which was converted to a defined benefit pension plan during the fourth quarter of 2008 (and therefore accounts for approximately half of the increase in the Postretirement Benefits liability on the Consolidated Balance Sheet at December 31, 2008), and UK pension plan are a combined 69% funded at December 31, 2008 based on the projected benefit obligation.
The UK pension plan was 92% funded at December 31, 2007.
Schlumberger currently anticipates contributing approximately $400 million to $500 million to its defined benefit pension plans in 2009, subject to market and business conditions.  ?
During 2008 and 2007, certain holders of Schlumberger Limited 1.5% Series A Convertible Debentures due June 1, 2023 and 2.125% Series B Convertible Debentures due June 1, 2023 converted their debentures into Schlumberger common stock.
The following table summarizes these conversions:
