Our press release contains information regarding ROIC, which is a non-GAAP financial measure. We believe that ROIC is useful to investors as a measure of performance and of the effectiveness of the use of capital in our operations. We use ROIC as one measure to monitor and evaluate our performance. Our measure of ROIC may be different from that used by other companies. We define ROIC as the percentage resulting from the following calculation:

(b) average invested capital for the year, calculated as a five quarter rolling average using the sum of Short-term debt, Long-term debt, Shareowners’ equity, and accumulated amortization of goodwill and other intangible assets, minus Cash and cash equivalents, short-term investments, and long-term investments (fixed income securities), multiplied by;

(c) one minus the effective tax rate for the period.

ROIC is calculated as follows (in millions, except percentages):
