We define “adjusted net earnings” as net earnings as reported under GAAP before debt prepayment costs and AIT costs. We define “adjusted net earnings per diluted share” as net earnings per diluted share as reported under GAAP before debt prepayment costs and AIT costs. Also, we adjusted our 2012 earnings per share guidance to exclude debt prepayment costs.

We define “adjusted operating earnings” as operating earnings as reported under GAAP before AIT costs. “Adjusted operating margin” is adjusted operating earnings reflected as a percentage of revenue for the relevant period on a consolidated or segment basis.

We define “CMS adjusted operating earnings” as operating earnings before AIT costs. “CMS adjusted operating margin” is adjusted operating earnings reflected as a percentage of revenue for the relevant period on a segment basis.

We use adjusted operating earnings, adjusted operating margin, CMS adjusted operating earnings, CMS adjusted operating margin and adjusted earnings per diluted share to evaluate and assess the operational strength and performance of our business and of particular segments of our business. We believe these financial measures are relevant and useful for investors because it allows investors to have a better understanding of the Company’s actual operating performance unaffected by the AIT costs associated with recent acquisitions and by the costs associated with our recent debt refinancing. These financial measures should not be viewed as a substitute for, or superior to, operating earnings, in the case of adjusted operating earnings, or net earnings, the most directly comparable GAAP measures, as a measure of the Company’s operating performance.

The Company defines “free cash flow” as net cash flows provided by operating activities less capital expenditures. The Company uses free cash flow to provide investors with an additional perspective on the Company’s cash flow provided by operating activities after taking into account reinvestments. Free cash flow does not take into account debt service requirements and therefore does not reflect an amount available for discretionary purposes. The Company defines "free cash flow conversion ratio" as free cash flow expressed as a percentage of the Company's net earnings. The Company uses free cash flow conversion ratio to provide investors with a measurement of its ability to convert earnings into free cash flow. These financial measures should not be viewed as a substitute for, or superior to, net cash flows provided by operating activities, the most directly comparable GAAP measure, as a measure of the Company’s liquidity or operating performance.
