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 an asterisk *.
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 six business segments including royalty income and
pension expense to the extent that the cost is currently recognized under government Cost Accounting Standards (CAS).
Segment Operating Margin excludes unallocated corporate expenses, GAAP pension expense and the reversal of CAS
pension expense.
Reconciling items to total company Operating Margin are:
– GAAP pension expense reported separately as a reconciling item under the caption quot;Pension expense.quot;
– Reversal of CAS pension expense included in Segment Operating Margin as a cost recognized under CAS.
– Unallocated expenses which include unallocated corporate, legal, environmental, state income tax, and other retiree
benefits expenses.
– Royalty Income reversed under the caption “Reversal of royalty income included above” and reported under the
caption “Other, net.”
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.
