cash from operating activities was $ 1436 million , $ 1310 million , and $ 1345 million in 2011 , 2010 , and 2009 , respectively .

cash provided by working capital was greater in 2009 than 2010 and that decline was more than offset by the cash from higher 2010 earnings .

we expect to make share repurchases in 2012 as part of our cash deployment focused on earnings growth .
