[['change in assumption', 'estimatedincrease to 2008pensionexpense ( in millions )'], ['.5% ( .5 % ) decrease in discount rate', '$ 1'], ['.5% ( .5 % ) decrease in expected long-term return on assets', '$ 10'], ['.5% ( .5 % ) increase in compensation rate', '$ 2']]
we currently estimate a pretax pension benefit of $ 26 million in 2008 compared with a pretax benefit of $ 30 million in .

Question: does a .5% ( .5 % ) decrease in discount rate have a greater impact on pension expense than a .5% ( .5 % ) decrease in expected long-term return on assets?
Answer: no
