11. Non-GAAP Measures Definitions
Non-GAAP Financial Measures Disclosure
Today’s presentation and the accompanying web charts contain non-GAAP (Generally Accepted
Accounting Principles) financial measures, as defined by SEC Regulation G and indicated by a footnote.
While we believe that these non-GAAP financial measures may be useful in evaluating Northrop Grumman,
this information should be considered as supplemental in nature and not as a substitute for financial
information prepared in accordance with GAAP.
Definitions are provided for the non-GAAP measures used in our presentation. Other companies may
define the measures differently.
Segment Operating Margin
Segment Operating Margin is the total earnings from each of our seven segments including allocated
pension expense recognized under government Cost Accounting Standards (CAS).
Reconciling items to total company Operating Margin are:
– Unallocated & other expenses, which include unallocated corporate, legal, environmental, state income tax, and other
retiree benefits expenses.
– Net pension expense, which includes GAAP pension expense less the CAS pension expense included in Segment
Operating Margin.
Management uses segment operating margin as an internal measure of financial performance of our
individual business segments. This measure also may be helpful to investors in understanding period-over-
period operating results separate from items that may be influenced by external market fluctuations.
Free Cash Flow
Free cash flow (FCF) is the cash from operations less capital expenditures and outsourcing contract &
related software costs.
