( 1 ) repurchases made pursuant to the $ 1.5 billion stock repurchase program approved by our board of directors in february 2008 .
under this program , our management is authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices as permitted by securities laws and other legal requirements , and subject to market conditions and other factors .
to facilitate repurchases , we make purchases pursuant to a trading plan under rule 10b5-1 of the exchange act , which allows us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods .
this program may be discontinued at any time .
as reflected in the above table , in the fourth quarter of 2008 , we significantly reduced purchases of common stock under our stock repurchase program based on the downturn in the economy and the disruptions in the financial and credit markets .
subsequent to december 31 , 2008 , we repurchased approximately 28000 shares of our common stock for an aggregate of $ 0.8 million , including commissions and fees , pursuant to this program .
we expect to continue to manage the pacing of the program in the future in response to general market conditions and other relevant factors. .
