RECONCILIATION OF AMOUNTS ADJUSTED FOR CERTAIN NON-RECURRING ITEMS WITH UNADJUSTED AMOUNTS

Table 2 includes amounts adjusted for certain non-recurring items, including segment operating income, unallocated corporate expense, non-operating income, net interest expense, income before income taxes, income taxes and net income, in each case as adjusted to exclude certain costs, expenses, charges or other amounts as described in the notes to Table 2. Harris management believes that these adjusted amounts, when considered together with the unadjusted amounts, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any particular period. Harris management also believes that these adjusted amounts enhance the ability of investors to analyze Harris’ business trends and to understand Harris’ performance. In addition, Harris may utilize adjusted amounts as guides in forecasting, budgeting and long-term planning processes and to measure operating performance for some management compensation purposes. Any analysis of adjusted amounts should be used only in conjunction with unadjusted amounts. The notes accompanying Table 2 provide a reconciliation of these adjusted amounts with the most directly comparable unadjusted amount.
