Non-GAAP Measures Disclosures
We supplement the reporting of our financial information determined under U.S. generally accepted accounting
principles (GAAP) with certain non-GAAP financial information. The non-GAAP financial information presented excludes certain
significant items that may not be indicative of, or are unrelated to, results from our ongoing business operations. We believe that
these non-GAAP measures provide investors with additional insight into the company’s ongoing business performance. These
non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other
companies may define such measures differently. We encourage investors to review our financial statements and publicly-filed
reports in their entirety and not to rely on any single financial measure. The following definitions are provided:
Core Operating Earnings, Core Operating Margin and Core Earnings Per Share
Core operating earnings is defined as GAAP earnings from operations excluding unallocated pension and postretirement
expense. Core operating margin is defined as core operating earnings expressed as a percentage of revenue. Core
earnings per share is defined as GAAP diluted earnings per share excluding the net earnings per share impact of unallocated
pension and post-retirement expense. Unallocated pension and post-retirement expense represents the portion of pension and
other post-retirement costs that are not recognized by business segments for segment reporting purposes. Management uses
core operating earnings, core operating margin and core earnings per share for purposes of evaluating and forecasting
underlying business performance. Management believes these core earnings measures provide investors additional insights
into operational performance as they exclude unallocated pension and post-retirement costs, which primarily represent costs
driven by market factors and costs not allocable to government contracts. A reconciliation between the GAAP and non-GAAP
measures is provided on page 14.
Operating Cash Flow Before Pension Contributions
Operating cash flow before pension contributions is defined as GAAP operating cash flow without pension
contributions. Management believes operating cash flow before pension contributions provides additional insights into underlying
business performance. Management uses operating cash flow before pension contributions as a measure to assess both
business performance and overall liquidity. Table 2 provides a reconciliation between GAAP operating cash flow and operating
cash flow before pension contributions.
Free Cash Flow
Free cash flow is defined as GAAP operating cash flow without capital expenditures for property, plant and equipment
additions. Management believes free cash flow provides investors with an important perspective on the cash available for
shareholders, debt repayment, and acquisitions after making the capital investments required to support ongoing business
operations and long term value creation. Free cash flow does not represent the residual cash flow available for discretionary
expenditures as it excludes certain mandatory expenditures such as repayment of maturing debt. Management uses free cash
flow as a measure to assess both business performance and overall liquidity. Table 2 provides a reconciliation between GAAP
operating cash flow and free cash flow.
