Notes:
(1) The corporate and other segment includes the results from the power segment for the periods prior to the year ended March 31, 2009.
(2) Segment profit is calculated by adjusting operating income for depreciation, depletion and amortization, voluntary retirement scheme
expenses, guarantees, impairment of investments and loans and gain on sale of real estate, as applicable. Segment profit is not a
recognized measurement under US GAAP. Our segment profit may not be comparable to similarly titled measures reported by other
companies due to potential inconsistencies in the method of calculation. We have included our segment profit because we believe it is an
indicative measure of our operating performance and is used by investors and analysts to evaluate companies in our industry. Our
segment profit should be considered in addition to, and not as a substitute for, other measures of financial performance and liquidity
reported in accordance with US GAAP. We believe that the inclusion of supplementary adjustments applied in our presentation of
segment profit are appropriate because we believe it is a more indicative measure of our baseline performance as it excludes certain
charges that our management considers to be outside of our core operating results. In addition, our segment profit is among the primary
indicators that our management uses as a basis for planning and forecasting of future periods. The following table reconciles operating
income to segment profit for the periods presented:
