Hubbell Incorporated (“Hubbell”) has calculated the ratio of earnings to fixed charges by dividing “earnings,” consisting of income from continuing operations before income taxes and fixed charges for the periods indicated, by Hubbell’s “fixed charges,” consisting of interest expense (which includes interest on indebtedness, the amortization of discounts, and the amortization of capitalized debt issuance costs) and the portion of estimated rents that Hubbell believes to be representative of the interest factor (one-third of rental expense), in each case for the periods indicated.
