__________________ 
(a) Earnings were inadequate to cover the fixed charges by $602.5 million in the fiscal year ended June 30, 2009.
For purposes of calculating the ratio of earnings to fixed charges, earnings is the amount resulting from adding earnings before income taxes, plus fixed charges. Fixed charges for these purposes include interest expense, amortization of bond issuance costs, and one-third of rental expense, which KLA-Tencor considers to be a reasonable approximation of the interest factor included in rental expense.
