pre_text: financing activities the decrease in cash used in 2010 relative to 2009 was attributable to a decrease in commercial paper repayments , net of proceeds , proceeds from our share issuance to bm&fbovespa as well as the termination of the nymex securities lending program in 2009 .
the decrease was partially offset by the distribution to dow jones of $ 607.5 million related to index services as well as an increase in share repurchases of $ 548.3 million .
share repurchases increased in an effort to offset most of the dilution associated with the issuance of shares to bm&fbovespa .
the increase in cash used in 2009 relative to 2008 was due to new issuances of debt of $ 2.9 billion in 2008 in conjunction with our merger with nymex holdings compared with net debt reductions of $ 900.1 million in debt instruments .
the following table summarizes our debt outstanding as of december 31 , 2010: .
