NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS

1.  Description of Business

L-3 Communications Holdings, Inc. derives all of its operating income and cash flows from its wholly-owned subsidiary, L-3 Communications Corporation (L-3 Communications). L-3 Communications Holdings, Inc. (L-3 Holdings and, together with its subsidiaries, referred to herein as L-3 or the Company) is a prime contractor in Command, Control, Communications, Intelligence, Surveillance and Reconnaissance (C³ISR) systems, aircraft modernization and maintenance, and government services.

The Company has the following four reportable segments: (1) C³ISR, (2) Government Services, (3) Aircraft Modernization and Maintenance (AM&M), and (4) Electronic Systems. Financial information with respect to each of the Company’s reportable segments is included in Note 21. C³ISR provides products and services for the global ISR market, C³ systems, networked communications systems and secure communications products. The Company believes that these products and services are critical elements for a substantial number of major command, control and communication, intelligence gathering and space systems. These products and services are used to connect a variety of airborne, space, ground and sea-based communication systems and are used in the transmission, processing, recording, monitoring, and dissemination functions of these communication systems. Government Services provides a full range of engineering, technical, analytical, information technology (IT), advisory, training, logistics and support services to the DoD, DoS, DoJ, and U.S. Government intelligence agencies and allied foreign governments.

2.  Basis of Presentation

These unaudited condensed consolidated financial statements for the quarterly and year-to-date periods ended September 24, 2010 should be read in conjunction with the audited consolidated financial statements of L-3 Holdings and L-3 Communications included in their Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

The accompanying financial statements comprise the consolidated financial statements of L-3 Holdings and L-3 Communications. L-3 Holdings’ only asset is its investment in the common stock of L-3 Communications, its wholly-owned subsidiary, and its only obligations are: (1) the 3% Convertible Contingent Debt Securities (CODES) due 2035, which were issued by L-3 Holdings on July 29, 2005, (2) its guarantee of borrowings under the revolving credit facility of L-3 Communications and (3) its guarantee of other contractual obligations of L-3 Communications and its subsidiaries. L-3 Holdings’ obligations relating to the CODES have been jointly, severally, fully and unconditionally guaranteed by L-3 Communications and certain of its wholly-owned domestic subsidiaries. Accordingly, such debt has been reflected as debt of L-3 Communications in its consolidated financial statements in accordance with the accounting standards for pushdown accounting. All issuances of and conversions into L-3 Holdings’ equity securities, including grants of stock options, restricted stock, restricted stock units and performance units by L-3 Holdings to employees and directors of L-3 Communications and its subsidiaries, have been reflected in the consolidated financial statements of L-3 Communications. As a result, the consolidated financial positions, results of operations and cash flows of L-3 Holdings and L-3 Communications are substantially the same. See Note 23 for additional information regarding the unaudited financial information of L-3 Communications and its subsidiaries.

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, they do not include all of the disclosures required by U.S. GAAP for a complete set of annual audited financial statements. In the opinion of management, all adjustments

L-3 COMMUNICATIONS HOLDINGS, INC.
AND L-3 COMMUNICATIONS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (Continued)

(consisting of normal and recurring adjustments) considered necessary for a fair presentation of the results for the interim periods presented have been included. The results of operations for the interim periods are not necessarily indicative of results for the full year.

It is the Company’s established practice to close its books for the quarters ending March, June and September on the Friday nearest to the end of the calendar quarter. The interim unaudited condensed consolidated financial statements included herein have been prepared and are labeled based on that convention. The Company closes its books for annual periods on December 31 regardless of what day it falls on.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and costs of sales during the reporting period. The most significant of these estimates and assumptions relate to contract revenue, profit and loss recognition, fair values of assets acquired and liabilities assumed in business combinations, market values for inventories reported at lower of cost or market, pension and post-retirement benefit obligations, stock-based employee compensation expense, income taxes, including the valuations of deferred tax assets, litigation reserves and environmental obligations, accrued product warranty costs, and the recoverability, useful lives and valuation of recorded amounts of long-lived assets, identifiable intangible assets and goodwill. Changes in estimates are reflected in the periods during which they become known. Actual amounts will differ from these estimates and could differ materially. For a more complete discussion of these estimates and assumptions, see the Annual Report of L-3 Holdings and L-3 Communications on Form 10-K for the fiscal year ended December 31, 2009.

During the quarter ended June 25, 2010, the Company made certain reclassifications between its Government Services and Electronic Systems reportable segments due to a re-alignment of a business unit in the Company’s management and organizational structure. See Note 21 for the prior period amounts reclassified between reportable segments.

Certain reclassifications have been made to conform prior year amounts to the current year presentation.

3.  New Accounting Standards Implemented

In June 2009, the Financial Accounting Standards Board (FASB) issued a revised standard for the accounting for variable interest entities (VIE), which replaces the quantitative-based risks and rewards approach with a qualitative approach and requires certain additional disclosures. The new qualitative approach focuses on determining which entity has the power and control to direct the activities of a VIE and requires an ongoing assessment of that conclusion. The revised accounting standard was effective for the Company beginning on January 1, 2010 and did not have a material impact on the Company’s financial position, results of operations or cash flows.

4.  Acquisitions

All of the business acquisitions are included in the Company’s results of operations from their respective dates of acquisition.

2010 Business Acquisitions

During the year-to-date period ended September 24, 2010, in separate transactions, the Company acquired three businesses for an aggregate purchase price of $705 million, which was financed with cash on hand. Based on preliminary purchase price allocations, the aggregate goodwill recognized for these businesses was $506 million, of which $490 million is expected to be deductible for income tax purposes. The goodwill was assigned to the Electronic Systems reportable segment. The Company also recognized identifiable intangible assets of $133 million in the aggregate, which primarily consisted of customer relationships and technology. The identifiable intangible assets will be amortized over a weighted average useful life of 13 years. A description of each business acquisition made by the Company during the year-to-date period ended September 24, 2010 is listed below:

•   On September 17, 2010, the Company acquired 3Di Technologies (3Di), a provider of highly specialized end-to-end secure communications utilized by forward-deployed U.S. special operations and in-theater personnel. The purchase price for 3Di is

AND L-3 COMMUNICATIONS CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (Continued)

subject to additional, contingent consideration not to exceed $11 million based upon 3Di’s post-acquisition financial performance through December 31, 2012. The Company recorded a $9 million liability on the acquisition date for the fair value of the contingent consideration, which was unchanged at September 24, 2010;

•   On August 4, 2010, the Company acquired all of the outstanding stock of Airborne Technologies, Inc. (ATI), a provider of highly specialized aeronautical engineering expertise, manufacturing and operations support for unmanned aircraft systems; and

•   On April 14, 2010, the Company acquired all of the outstanding stock of Insight Technology Incorporated (Insight), a manufacturer of mission critical night vision and electro-optical equipment.

The final purchase price for 3Di and ATI is subject to adjustment based on closing date actual net assets and net working capital, respectively. The final purchase price allocations for the 2010 business acquisitions are expected to be completed by the fourth quarter of 2010 and will be based on the final purchase prices and final appraisals and other analyses of fair values for acquired assets and assumed liabilities. The Company does not expect any of the differences between the preliminary and final purchase price allocations to have a material impact on its results of operations or financial position.

2009 Business Acquisitions

On January 30, 2009, the Company acquired all of the outstanding stock of Chesapeake Sciences Corporation (CSC) for a purchase price of $91 million in cash, which included a $7 million net working capital adjustment and $4 million related to certain tax benefits acquired. The net working capital adjustment included $6 million for cash acquired. The acquisition was financed using cash on hand. CSC is a developer and manufacturer of anti-submarine warfare systems for use onboard submarines and surface ship combatants. Based on the final purchase price allocation, the amount of goodwill recognized was $56 million, which was assigned to the Electronic Systems reportable segment, and is not expected to be deductible for income tax purposes.

Inventoried Contract Costs. In accordance with contract accounting standards, the Company accounts for the portion of its general and administrative (G&A), independent research and development (IRAD) and bid and proposal (B&P) costs that are allowable and reimbursable indirect contract costs under U.S. Government procurement regulations on its U.S. Government contracts (revenue arrangements) as inventoried contract costs. G&A, IRAD and B&P costs are allocated to contracts for which the U.S. Government is the end customer and are charged to costs of sales when sales on the related contracts are recognized.

Holdings’ common stock. See Note 10 to the audited consolidated financial statements for the year ended December 31, 2009, included in the Company’s Annual Report on Form 10-K for additional information regarding the CODES, including conditions for conversion. L-3 Holdings’ closing stock price on November 1, 2010 was $72.69 per share. The effective interest rate on the CODES is 6.33%. Interest expense relates to both the contractual coupon interest and amortization of the discount on the liability components. Interest expense recognized was $11 million for each of the third quarter periods ended September 24, 2010 and September 25, 2009, $32 million for the year-to-date period ended September 24, 2010, and $31 million for the year-to-date period ended September 25, 2009. The following table provides additional information about the Company’s CODES:

⁽³⁾ The current portion of long-term debt at September 24, 2010 includes the carrying value of L-3 Holdings’ $700 million CODES, as the holders of the CODES may require us to repurchase them in whole or in part at a cash price equal to 100% of the principal amount (plus accrued and unpaid interest, including contingent interest and additional interest, if any) through the exercise of a “put” option on February 1, 2011.

On May 21, 2010, L-3 Communications issued $800 million in principal amount of 4.75% Senior Notes that mature on July 15, 2020 (2020 Senior Notes) at a discount of $3 million. The discount was recorded as a reduction to the principal amount of the notes and will be amortized as interest expense over the term of the notes. The effective interest rate of the 2020 Senior Notes is 4.79%. Interest on the 2020 Senior Notes is payable semi-annually on January 15 and July 15 of each year, commencing on January 15, 2011. The net cash proceeds from this offering amounted to approximately $790 million after deducting the discounts, commissions and estimated expenses, and were used, together with cash on hand, to redeem L-3 Communications’ $800 million in aggregate 6¹/₈% Senior Subordinated Notes due 2014 and 2013 (collectively, the Subordinated Notes) on June 21 and July 15, 2010, respectively. In connection with the redemption of the Subordinated Notes, the Company recorded debt retirement charges of approximately $13 million ($8 million after income tax, or $0.07 per diluted share) during the second quarter ended June 25, 2010 and $5 million ($3 million after income tax, or $0.03 per diluted share) during the third quarter ended September 24, 2010.

In addition, the Company has numerous state and foreign income tax return audits currently in process. As of September 24, 2010, the Company anticipates that unrecognized tax benefits will decrease by approximately $22 million over the next 12 months.

Current and non-current income taxes payable include accrued potential interest of $21 million ($13 million after income taxes) at September 24, 2010 and $23 million ($14 million after income taxes) at December 31, 2009, and potential penalties of $11 million at September 24, 2010 and $9 million at December 31, 2009.

⁽¹⁾ L-3 Holdings’ CODES had no impact on diluted EPS for the quarter or year-to-date periods ended September 24, 2010 or September 25, 2009 because the average market price of L-3 Holdings common stock during these periods was less than the price at which the CODES would have been convertible into L-3 Holdings common stock. As of May 14, 2010, the conversion price was $98.94.

16.  Derivative Financial Instruments

The Company’s derivative financial instruments include foreign currency forward contracts, which are entered into for risk management purposes, and an embedded derivative representing the contingent interest payment provision related to the CODES.

Foreign Currency Forward Contracts. The Company’s U.S. and foreign businesses enter into contracts with customers, subcontractors or vendors that are denominated in currencies other than their functional currencies. To protect the functional currency equivalent cash flows associated with certain of these contracts, the Company enters into foreign currency forward contracts. The Company’s activities involving foreign currency forward contracts are designed to hedge the changes in the functional currency equivalent cash flows due to movements in foreign exchange rates compared to the functional currency. The foreign currencies hedged are primarily the Canadian dollar, the Euro, the British pound and the U.S. dollar. The Company manages exposure to counterparty non-performance credit risk by entering into foreign currency forward contracts only with major financial institutions that are expected to fully perform under the terms of such contracts. Foreign currency forward contracts are recorded in the Company’s condensed consolidated balance sheets at fair value and are generally designated and accounted for as cash flow hedges in accordance with the accounting standards for derivative instruments and hedging activities. Gains and losses on designated foreign currency forward contracts that are highly effective in offsetting the corresponding change in the cash flows of the hedged transactions are recorded net of income taxes in accumulated other comprehensive income (loss) (accumulated OCI) and then recognized in income when the underlying hedged transaction affects income. Gains and losses on foreign currency forward contracts that do not meet hedge accounting criteria are recognized in income immediately.

Notional amounts are used to measure the volume of foreign currency forward contracts and do not represent exposure to foreign currency losses. The table below presents the notional amounts of the Company’s outstanding foreign currency forward contracts by currency at September 24, 2010:

Currency	Notional Amount
	(in millions)
Canadian dollar	$	201
U.S. dollar		92
British pound		70
Euro		34
Other		4
Total	$	401

At September 24, 2010, the Company’s foreign currency forward contracts had maturities through 2016.

Embedded Derivative. The embedded derivative related to the issuance of the CODES is recorded at fair value with changes reflected in the unaudited condensed consolidated statements of operations.

The effect of gains or losses from foreign currency forward contracts was not material to the unaudited condensed consolidated statements of operations for the quarter and year-to-date periods ended September 24, 2010 and September 25, 2009. At September 24, 2010, the estimated net existing gain that is expected to be reclassified into income within the next 12 months is $3 million.

17.  Commitments and Contingencies

A substantial majority of the Company’s revenues are generated from providing products and services under legally binding agreements or contracts with U.S. Government and foreign government customers. U.S. Government contracts are subject to extensive legal and regulatory requirements, and from time to time, agencies of the U.S. Government investigate whether such contracts were and are being conducted in accordance with these requirements. The Company is currently cooperating with the U.S. Government on several investigations, including those specified below, from which civil, criminal or administrative proceedings have or could result and give rise to fines, penalties, compensatory and treble damages, restitution and/or forfeitures. The Company does not currently anticipate that any of these investigations will have a material adverse effect, individually or in the aggregate, on its consolidated financial position, results of operations or cash flows. However, under U.S. Government regulations, an indictment of the Company by a federal grand jury, or an administrative finding against the Company as to its present responsibility to be a U.S. Government contractor or subcontractor, could result in the Company being suspended for a period of time from eligibility for awards of new government contracts or task orders or in a loss of export privileges. A conviction, or an administrative finding against the Company that satisfies the requisite level of seriousness, could result in debarment from contracting with the federal government for a specified term. In addition, all of the Company’s U.S. Government contracts: (1) are subject to audit and various pricing and cost controls, (2) include standard provisions for termination for the convenience of the U.S. Government or for default, and (3) are subject to cancellation if funds for contracts become unavailable. Foreign government contracts generally include comparable provisions relating to terminations for convenience and default, as well as other procurement clauses relevant to the foreign government.

The Company is also subject to and is involved in litigation, proceedings, claims or assessments and various contingent liabilities incidental to its businesses, including those specified below. Furthermore, in connection with certain business acquisitions, the Company has assumed some or all claims against, and liabilities of, the acquired business, including both asserted and unasserted claims and liabilities. In accordance with the accounting standard for contingencies, the Company records a liability when management believes that it is both probable that a liability has been incurred and the Company can reasonably estimate the amount of the loss. Generally, the loss is recorded at the amount the Company expects to resolve the liability. The estimated amounts of liabilities recorded for pending and threatened litigation are disclosed in Note 8. Amounts recoverable from insurance contracts or third parties are recorded as assets when deemed probable. At September 24, 2010, the Company had recorded approximately $2 million for recoveries from insurance contracts or third parties in connection with the amount of liabilities recorded for pending

and threatened litigation. Legal defense costs are expensed as incurred. The Company believes it has recorded adequate provisions for its litigation and government investigation matters. The Company reviews these provisions quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. While it is reasonably possible that an unfavorable outcome may occur in one or more of the matters discussed below, unless otherwise stated, the Company believes that it is not probable that a loss has been incurred in any of these matters. An estimate of loss or range of loss is disclosed for a particular litigation matter when such amount or amounts can be reasonably estimated and no loss has been accrued. The Company believes that any damage amounts claimed in the specific matters discussed below are not meaningful indicators of potential liability. Although the Company believes that it has valid defenses with respect to legal matters and investigations pending against it, these matters are inherently unpredictable, including those that are expected to be resolved with jury trials, for which outcomes are difficult to predict. Therefore, it is possible that the financial position, results of operations or cash flows of the Company could be materially adversely affected in any particular period by the unfavorable resolution of one or more of these or other contingencies.

Kalitta Air. On January 31, 1997, a predecessor of Kalitta Air filed a lawsuit in the U.S. District Court for the Northern District of California (the trial court) asserting, among other things, negligence and negligent misrepresentation against Central Texas Airborne Systems, Inc. (CTAS), a predecessor to L-3 Integrated Systems (L-3 IS), in connection with work performed by a predecessor to CTAS to convert two Boeing 747 aircraft from passenger configuration to cargo freighters. The work was performed using Supplemental Type Certificates (STCs) issued in 1988 by the Federal Aviation Administration (FAA). In 1996, following completion of the work, the FAA issued an airworthiness directive with respect to the STCs that effectively grounded the aircraft. On August 11, 2000, the trial court granted CTAS’ motion for summary judgment as to negligence, dismissing that claim. In January 2001, after a ruling by the trial court that excluded certain evidence from trial, a jury rendered a unanimous defense verdict in favor of CTAS on the negligent misrepresentation claim. On December 10, 2002, the U.S. Court of Appeals for the Ninth Circuit (the Court of Appeals) reversed the trial court’s decisions as to summary judgment and the exclusion of evidence, and remanded the case for a new trial on both the negligence and negligent misrepresentation claims. The retrial ended on March 2, 2005 with a deadlocked jury and mistrial. On July 22, 2005, the trial court granted CTAS’ motion for judgment as a matter of law as to negligence, dismissing that claim, and denied CTAS’ motion for judgment as a matter of law as to negligent misrepresentation. On October 8, 2008, the Court of Appeals reversed the trial court’s dismissal of the negligence claim and affirmed the trial court’s ruling as to the negligent misrepresentation claim. As a result, the case was remanded to the trial court to reconsider the negligence claim and for further proceedings on the negligent misrepresentation claim. The trial court held a new hearing on CTAS’ motion to dismiss the negligence claim on April 30, 2009, after which it determined to take the matter under advisement. The case is currently scheduled to go to a third trial on October 31, 2011. The parties have participated in court-ordered mediations from time to time, and are expected to participate in future court-ordered mediations prior to trial, but to date such mediations have not resulted in a mutually acceptable resolution of this matter. In connection with these mediations, Kalitta Air has claimed it may seek damages at the third trial of between $430 million and $900 million, including between $200 million and $240 million of pre-judgment interest. CTAS’ insurance carrier has accepted defense of this matter and has retained counsel, subject to a reservation of rights by the insurer to dispute its obligations under the applicable insurance policies in the event of a finding against L-3. The Company believes that it has meritorious defenses to the claims asserted and the damages sought and intends to defend itself vigorously.

Korean Lot II Program. On April 4, 2005, Lockheed Martin Corporation (Lockheed) filed a lawsuit in the U.S. District Court for the Northern District of Georgia alleging that L-3 IS is in breach of its license agreement with Lockheed and is infringing on Lockheed’s intellectual property rights as a result of its performance of a subcontract awarded to L-3 IS for the Korean Lot II program. On October 26, 2010, the parties agreed to settle this matter and entered into a licensing agreement under which each party licenses to the other the right to use intellectual property related to P-3 aircraft.

SSPD Investigation. As previously disclosed, on June 4, 2010, the Company received notice that Integrated Systems’ Special Support Programs Division (L-3 SSPD, formerly known as L-3 Joint Operations Group or JOG) had been temporarily suspended from receiving new contracts or orders from U.S. Government agencies in connection with a governmental investigation of L-3 SSPD relating to the Special Operations Forces Support Activity (SOFSA) contract. On July 27, 2010, the Company and the U.S. Air Force entered into an administrative agreement under which the Air Force lifted the temporary suspension and L-3 agreed, among other things, to provide periodic reporting to the Air Force regarding its ethics and compliance programs and not to protest the award of the follow-on SOFSA contract to a competitor.

Derivative Action. As previously disclosed, on July 15, 2010, a stockholder derivative complaint was filed in the Supreme Court of the State of New York, New York County, against the Company’s directors and also against the Company as a nominal defendant. The complaint asserts, among other things, breaches of fiduciary duty and unjust enrichment based on allegations that the Company’s directors acquiesced in, or failed to prevent, conduct at issue in the SSPD Investigation matter described above. The complaint seeks, among other things, monetary damages, equitable relief and an award of fees and expenses.

Aircrew Training and Rehearsal Support (ATARS) Investigation. Following a lawsuit filed by Lockheed on April 6, 2006 in the U.S. District Court for the Middle District of Florida against the Company and certain individuals related to the ATARS II Program (which was settled in November 2007), the Company received Grand Jury subpoenas in November 2006 and December 2007 in connection with an investigation being conducted by the United States Attorney for the Middle District of Florida, Orlando Division. The subpoenas request the production of documents related to Lockheed’s allegations or produced in the civil litigation. The Company is cooperating fully with the U.S. Government.

Titan Government Investigation. In October 2002, The Titan Corporation (Titan) received a grand jury subpoena from the Antitrust Division of the DoJ requesting the production of documents relating to information technology services performed for the U.S. Air Force at Hanscom Air Force Base in Massachusetts and Wright-Patterson Air Force Base in Ohio. Titan was informed that other companies who have performed similar services had received subpoenas as well. The Company acquired Titan in July 2005. On September 20, 2006, counsel for the Company was informed by the New York Field Office of the DoJ’s Criminal Antitrust Division that it was considering indictment. Additionally, a former Titan employee received a letter from the DoJ indicating that he was a target of the investigation. In December 2008, the DoJ contacted the Company to arrange additional employee interviews concerning a teaming agreement relating to the Wright-Patterson Air Force Base procurement. In January 2010, counsel for the Company was again informed by the New York Field Office that it was considering indictment. If the Field Office recommends indictment then, under normal DoJ procedures, Titan (now known as L-3 Services, Inc.) will be afforded an opportunity to make a presentation to the Criminal Antitrust Division in Washington, D.C. before the DoJ acts on the recommendation. It is not known whether an indictment of L-3 Services or any of its current or former employees will occur. If it does occur, it is possible that L-3 Services could be suspended or debarred from conducting business with the U.S. Government. The Company is cooperating fully with the U.S. Government.

CyTerra Government Investigation. Since November 2006, CyTerra has been served with civil and Grand Jury subpoenas by the DoD Office of the Inspector General and the DoJ and has been asked to facilitate employee interviews. The Company is cooperating fully with the U.S. Government. The Company believes that it is entitled to indemnification for any course of defense related to this matter out of, and has made a claim against, a $15 million escrow fund established in connection with the Company’s acquisition of CyTerra in March 2006.

Bashkirian Airways. On July 1, 2004, lawsuits were filed on behalf of the estates of 31 Russian children in the state courts of Washington, Arizona, California, Florida, New York and New Jersey against Honeywell, Honeywell TCAS, Thales USA, Thales France, the Company and Aviation Communications & Surveillance Systems (ACSS), which is a joint venture of L-3 and Thales. The suits relate to the crash over southern Germany of Bashkirian Airways Tupelov TU 154M aircraft and a DHL Boeing 757 cargo aircraft. On-board the Tupelov aircraft were 9 crew members and 60 passengers, including 45 children. The Boeing aircraft carried a crew of two. Both aircraft were equipped with Honeywell/ACSS Model 2000, Change 7 Traffic Collision and Avoidance Systems (TCAS). Sensing the other aircraft, the on-board DHL TCAS instructed the DHL pilot to descend, and the Tupelov on-board TCAS instructed the Tupelov pilot to climb. However, the Swiss air traffic controller ordered the Tupelov pilot to descend. The Tupelov pilot disregarded the on-board TCAS and put the Tupelov aircraft into a descent striking the DHL aircraft in midair at approximately 35,000 feet. All crew and passengers of both planes were lost. Investigations by the National Transportation Safety Board after the crash revealed that both TCAS units were performing as designed. The suits allege negligence and strict product liability based upon the design of the units and the training provided to resolve conflicting commands and seek approximately $315 million in damages, including $150 million in punitive damages. The Company’s insurers have accepted defense of this matter and have retained counsel. The matters were consolidated in the U.S. District Court for the District of New Jersey, which has dismissed the actions on the basis of forum non conveniens. The plaintiffs re-filed a complaint on April 23, 2007 with the Barcelona Court’s Registry in Spain. On

March 9, 2010, the court ruled in favor of the plaintiffs and entered judgment against ACSS in the amount of approximately $6.7 million, all of which represented compensatory damages. The Company believes that the verdict and the damages awarded are inconsistent with the law and evidence presented. Accordingly, ACSS filed an appeal of this ruling on April 27, 2010. The plaintiffs also filed an appeal of this ruling on the same date.

Gol Airlines. A complaint was filed on November 7, 2006 in the U.S. District Court for the Eastern District of New York against ExcelAire, Joseph Lepore, Jan Paul Paladino, and Honeywell. On October 23, 2007, an amended complaint was filed to include Lockheed, Raytheon, Amazon Technologies and ACSS. The complaints relate to the September 29, 2006 airplane crash over Brazil of a Boeing 737-800 operated by GOL Linhas Aereas Inteligentes, S.A. and an Embraer 600 business jet operated by ExcelAire. The complaints allege that ACSS designed the TCAS on the ExcelAire jet, and assert claims of negligence, strict products liability and breach of warranty against ACSS based on the design of the TCAS and the instructions provided for its use. The complaints seek unspecified monetary damages, including punitive damages. The Company’s insurers have accepted defense of this matter and have retained counsel. On July 2, 2008, the District Court dismissed the actions on the basis of forum non conveniens on the grounds that Brazil was the location of the accident and is more convenient for witnesses and document availability. On December 2, 2009, the U.S. Court of Appeals for the Second Circuit upheld this decision. Some of the plaintiffs re-filed their complaints in the Lower Civil Court in the Judicial District of Peixoto de Azevedo in Brazil on July 3, 2009.

The Company contributed cash of $115 million to its pension plans and $8 million to its postretirement benefit plans during the year-to-date period ended September 24, 2010.

19.  Employee Stock-Based Compensation

During the year-to-date period ended September 24, 2010, the Company granted stock-based compensation awards under the 2008 Long Term Performance Plan (2008 LTPP) in the form of stock options, restricted stock units and performance units.

Stock Options. The Company granted 555,363 stock options with an exercise price equal to the fair market value of L-3 Holdings’ common stock on the date of grant. The options expire after 10 years from the date of grant and vest ratably over a three-year period on the annual anniversary of the date of grant. The weighted average grant date fair value for the options awarded was $18.41 and was

estimated using the Black-Scholes option-pricing model. The weighted average assumptions used in the valuation model for options granted during the year-to-date period ended September 24, 2010 are presented in the table below:

Expected holding period (in years)	4.7
Expected volatility	26.2	%
Expected dividend yield	2.2	%
Risk-free interest rate	2.3	%

Restricted Stock Units. The Company granted 603,020 restricted stock units with a weighted average grant date fair value of $90.24 per share. These units automatically convert into shares of L-3 Holdings’ common stock upon vesting, and are subject to forfeiture until certain restrictions have lapsed, including a three year cliff vesting period for employees and a one year cliff vesting period for non-employee directors, in each case starting on the date of grant.

Performance Units. The Company granted 69,918 performance units with a weighted average grant date fair value per unit of $103.71. The payout for these units is based on the achievement of pre-determined performance goals established by the compensation committee of the Company’s Board of Directors for the three-year period ending December 31, 2012. The payout can range from zero to 200% of the original number of units awarded, which are converted into shares of L-3 Holdings’ common stock and/or an amount of cash based on the then existing closing price at the end of the performance period.

On April 27, 2010, the stockholders of L-3 Holdings approved an amendment to the 2008 LTPP. The principal purpose of the amendment was to increase the number of shares authorized for issuance under the 2008 LTPP to approximately 12.2 million shares, except that each share of L-3 Holdings’ common stock issued under a “full value” award (awards other than stock options or stock appreciation rights) will be counted as 2.6 shares for purposes of this share limit.

22.  Accounting Standards Issued and Not Yet Implemented

In October 2009, the FASB issued a revised accounting standard for revenue arrangements with multiple deliverables. The revision: (1) removes the objective-and-reliable-evidence-of-fair-value criterion from the separation criteria used to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, (2) provides a hierarchy that entities must use to estimate the selling price, (3) eliminates the use of the residual method for allocation, and (4) expands the ongoing disclosure requirements. The revised accounting standard is effective for the Company beginning on January 1, 2011. The Company is currently assessing the impact the revised accounting standard will have on its consolidated financial statements.

In October 2009, the FASB issued a revised accounting standard for certain revenue arrangements that include software elements. Under the revised standard, tangible products that contain both software and non-software components that work together to deliver a product’s essential functionality will be removed from the scope of pre-existing software revenue recognition standards. In addition, hardware components of a tangible product containing software components will always be excluded from software revenue recognition standards. The revised accounting standard is effective for the Company beginning on January 1, 2011. The Company is currently assessing the impact the revised accounting standard will have on its consolidated financial statements.

Overview and Outlook

L-3’s Business

L-3 is a prime contractor in Command, Control, Communications, Intelligence, Surveillance and Reconnaissance (C³ISR) systems, aircraft modernization and maintenance, and government services. L-3 is also a leading provider of a broad range of electronic systems used on military and commercial platforms. Our customers include the United States (U.S.) Department of Defense (DoD) and its prime contractors, U.S. Government intelligence agencies, the U.S. Department of Homeland Security (DHS), U.S. Department of State (DoS), U.S. Department of Justice (DoJ), allied foreign governments, domestic and foreign commercial customers, and select other U.S. federal, state and local government agencies.

For the year ended December 31, 2009, we generated sales of $15.6 billion. Our primary customer was the DoD. The table below presents a summary of our 2009 sales by major category of end customer and the percent contributed by each end customer to our total 2009 sales. We currently do not anticipate significant changes to our end customer sales mix for the year ending December 31, 2010.

			% of
	2009 Sales		2009 Sales
	(in millions)
DoD	$	11,932		76	%
Other U.S. Government		1,127		7
Total U.S. Government		13,059		83	%
Foreign governments		1,082		7
Commercial — foreign		867		6
Commercial — domestic		607		4
Total sales	$	15,615		100	%

We have the following four reportable segments: (1) C³ISR, (2) Government Services, (3) Aircraft Modernization and Maintenance (AM&M), and (4) Electronic Systems. Financial information with respect to each of our reportable segments is included in Note 21 to our unaudited condensed consolidated financial statements contained in this quarterly report. C³ISR provides products and services for the global ISR market, C³ systems, networked communications systems and secure communications products. We believe that these products and services are critical elements for a substantial number of major command, control and

28

communication, intelligence gathering and space systems. These products and services are used to connect a variety of airborne, space, ground and sea-based communication systems and are used in the transmission, processing, recording, monitoring, and dissemination functions of these communication systems. Government Services provides a full range of engineering, technical, analytical, information technology (IT), advisory, training, logistics and support services to the DoD, DoS, DoJ, and U.S. Government intelligence agencies and allied foreign governments. AM&M provides modernization, upgrades and sustainment, maintenance and logistics support services for military and various government aircraft and other platforms. We sell these services primarily to the DoD, the Canadian Department of National Defense and other allied foreign governments. Electronic Systems provides a broad range of products and services, including components, products, subsystems, systems, and related services to military and commercial customers in several niche markets across several business areas, including power & control systems, electro-optic/infrared (EO/IR), microwave, avionics and displays, simulation & training, precision engagement, security & detection, propulsion systems, telemetry & advanced technology, undersea warfare, and marine services.

Industry Considerations

As is the case with most other U.S. defense contractors, we have benefited from the upward trend in DoD budget authorization and spending outlays over recent years, including supplemental appropriations for military operations in Iraq and Afghanistan. We expect future DoD budgets, including supplemental appropriations, to grow at a significantly slower pace than the past several years, and to possibly flatten or decline. However, we believe that our businesses should be able to continue to generate modest sales growth because we anticipate the defense budget and spending priorities will continue to focus on several areas that match L-3’s core competencies, such as communications and ISR, sensors, special operations support, helicopter crew training and maintenance and simulation & training.

Key Performance Measures

The primary financial performance measures that L-3 uses to manage its businesses and monitor results of operations are sales growth and operating income growth. Management believes that these financial performance measures are the primary growth drivers for L-3’s earnings per common share and net cash from operating activities. One of L-3’s primary business objectives is to increase sales from organic growth and select business acquisitions. We define organic sales growth as the increase or decrease in sales for the current period compared to the prior period, excluding sales in the: (1) current period from business and product line acquisitions that are included in L-3’s actual results of operations for less than twelve months, and (2) prior period from business and product line divestitures that are included in L-3’s actual results of operations for the twelve-month period prior to the divestiture date. We expect to supplement our organic sales growth by selectively acquiring businesses that: (1) add important new technologies, services, and products, (2) provide access to select customers, programs and contracts, and (3) provide attractive returns on investments. The two main determinants of our operating income growth are sales growth and improvements in direct and indirect contract costs. We define operating margin as operating income as a percentage of sales. Improving operating margins is one method for growing earnings per common share and net cash from operating activities, but it is not the only one.

Sales Growth. Sales growth for the year ended December 31, 2009 was 5%, comprised of organic sales growth of 4%, and sales growth from business acquisitions, net of divestitures, of 1%. For the quarter ended September 24, 2010 (2010 Third Quarter), consolidated net sales of $3,835 million declined by 0.2%, comprised of an organic sales decline of 1.8%, partially offset by sales growth from acquisitions of $60 million or 1.6%, compared to the quarter ended September 25, 2009 (2009 Third Quarter). For the year-to-date period ended September 24, 2010 (2010 Year-to-Date Period), consolidated net sales of $11,425 million increased by 0.2%, comprised of sales growth from acquisitions of $127 million or 1.1%, partially offset by an organic sales decline of 0.9%, compared to the year-to-date period ended September 25, 2009 (2009 Year-to-Date Period).

For the year ended December 31, 2009, our largest contract (revenue arrangement) in terms of annual sales was the Special Operations Forces Support Activity (SOFSA) contract, which generated approximately 3% of our sales. On June 21, 2010, SOFSA unexpectedly announced that the SOFSA follow-on contract was awarded to another contractor. The transition to the successor contractor began immediately for a period of 120 days and ended in October 2010. We had previously expected, based on communication from the SOFSA customer, that an amended solicitation for the follow-on contract was to have been released in June 2010 with an award by January 2011. See Note 17 to our unaudited condensed consolidated financial statements contained in this quarterly report for further discussion.

Operating Margin. We are focused on increasing operating margin modestly, to the extent possible, by reducing our indirect costs and improving our overall contract performance. However, we may not be able to continue to expand our operating margin on an annual basis as business acquisitions and new business, including contract renewals and new contracts, could result in decreased operating margins if their margins are lower than L-3’s operating margin on existing business and contracts. In addition, changes in the competitive environment could also result in lower operating margin.

Other Events

Debt Issuance and Repayments. On May 21, 2010, L-3 Communications issued $800 million in principal amount of 4.75% Senior Notes that mature on July 15, 2020 (2020 Senior Notes) at a discount of $3 million. The net cash proceeds from this offering, together with cash on hand, were used to redeem L-3 Communications’ $800 million in aggregate 6¹/₈% Senior Subordinated Notes due 2014 and 2013 (collectively, the Subordinated Notes). In connection with the redemption of the Subordinated Notes, we recorded debt retirement charges of approximately $13 million ($8 million after income tax, or $0.07 per diluted share) during the 2010 second quarter and $5 million ($3 million after income tax, or $0.03 per diluted share) during the 2010 Third Quarter. See “Liquidity and Capital Resources — Debt” on page 37 for a further discussion.

Business Acquisitions and Business and Product Line Dispositions

Our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 summarizes the business acquisitions and business and product line dispositions that we completed during the three years ended December 31, 2009. Also, see Note 4 to our unaudited condensed consolidated financial statements contained in this quarterly report for a discussion of the acquisitions that we completed during the 2010 Year-to-Date Period. During the 2010 Year-to-Date Period, we used $710 million of cash primarily to acquire three businesses. All of our business acquisitions are included in our consolidated results of operations from their dates of acquisition. We regularly evaluate potential business acquisitions.

Results of Operations

The following information should be read in conjunction with our unaudited condensed consolidated financial statements contained in this quarterly report. Our results of operations for the periods presented are affected by our business acquisitions. See Note 4 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for a discussion of our 2009 business acquisitions, and Note 4 to our unaudited condensed consolidated financial statements, included in this report, for a discussion of our business acquisitions completed during the 2010 Year-to-Date Period.

Net Sales: For the 2010 Third Quarter, consolidated net sales decreased 0.2% compared to the 2009 Third Quarter. Sales growth primarily from the C³ISR reportable segment was offset by lower sales from the AM&M and Electronic Systems reportable segments. Net sales from acquired businesses were $60 million in the 2010 Third Quarter. Sales from services, which include services performed by businesses primarily in our Government Services, AM&M and C³ISR reportable segments, as well as marine services, simulation & training, and maintenance for security and detection systems within our Electronic Systems reportable segment, increased by $34 million to $2,066 million, representing approximately 54% of consolidated net sales for the 2010 Third Quarter, compared to $2,032 million, or approximately 53% of consolidated net sales for the 2009 Third Quarter. Service sales increased due primarily to organic sales growth in airborne ISR logistics support services for the U.S. Air Force, logistics, training, and law enforcement support services for the U.S. Army, information technology (IT) support services for the U.S. Special Operations Command (SOCOM) and other U.S. Government agencies, and systems field support services for U.S. Army rotary wing training aircraft. These increases were partially offset by reduced subcontractor pass-through sales for U.S. Army systems and software

30

engineering and sustainment (SSES) services and lower sales volume for systems field support services for U.S. Air Force fixed wing training aircraft, contract field services (CFS), SOFSA, marine services and Iraq support. Sales from products, which primarily include products from our C³ISR and Electronic Systems reportable segments, decreased by $41 million to $1,769 million, representing approximately 46% of consolidated net sales for the 2010 Third Quarter, compared to $1,810 million for the 2009 Third Quarter, or approximately 47% of consolidated net sales for the 2009 Third Quarter. The decrease was primarily due to sales volume declines for commercial ship building products, precision engagement, combat propulsion systems and the Joint Cargo Aircraft (JCA) contract. These decreases were partially offset by organic sales growth in EO/IR, security & detection systems, aircraft modernization, networked communications and sales from the Insight Technology (Insight) acquired business.

For the 2010 Year-to-Date Period, consolidated net sales increased 0.2% compared to the 2009 Year-to-Date Period. Sales growth from the C³ISR and AM&M reportable segments was offset by lower sales from the Government Services and Electronic Systems reportable segments. Net sales from acquired businesses were $127 million in the 2010 Year-to-Date Period. Sales from services increased by $70 million to $6,021 million, representing approximately 53% of consolidated net sales for the 2010 Year-to-Date Period, compared to $5,951 million, or approximately 52% of consolidated net sales for the 2009 Year-to-Date Period. Service sales increased primarily due to organic sales growth in airborne ISR logistic support services for the U.S. Air Force, logistics, training and law enforcement support services for the U.S. Army, systems field support services for U.S. Army rotary wing training aircraft, and IT support services for SOCOM and other U.S. Government agencies. These increases were partially offset by reduced subcontractor pass-through sales for U.S. Army SSES services, a decrease for Iraq support, lower volume for CFS and the SOFSA contract, and lower systems field support services for U.S. Air Force fixed wing training aircraft. Sales from products decreased by $52 million to $5,404 million, or approximately 47% of consolidated net sales for the 2010 Year-to-Date Period, compared to $5,456 million, or 48% of consolidated net sales for the 2009 Year-to-Date Period. The decrease in product sales was primarily due to decreases for combat propulsion systems, commercial shipbuilding products, precision engagement and marine services. These decreases were partially offset by organic sales growth for aircraft modernization, EO/IR, microwave, security and detection systems, and networked communications and sales from the Insight acquired business. See the reportable segment results below for additional discussion of our sales results.

Operating income and operating margin: Operating income for the 2010 Third Quarter increased by 5% compared to the 2009 Third Quarter. Operating margin increased to 11.4% for the 2010 Third Quarter compared to 10.9% for the 2009 Third Quarter. Favorable sales mix across several businesses in the Electronic Systems reportable segment was partially offset by lower operating margins in the Government Services and AM&M reportable segments.

Operating income for the 2010 Year-to-Date Period increased by 6% compared to the 2009 Year-to-Date Period. Operating margin increased to 11.3% for the 2010 Year-to-Date Period from 10.6% for the 2009 Year-to-Date Period. The increase in operating margin was primarily driven by higher sales and improved contract performance for the C³ISR reportable segment and favorable sales mix across several businesses in the Electronic Systems reportable segment. In addition, lower pension expense of $10 million ($6 million after income taxes, or $0.05 per diluted share) increased operating margin by 10 basis points. These increases were partially offset by lower operating margins in the Government Services and AM&M reportable segments. See the reportable segment results below for additional discussion of our segment operating margin.

Net interest expense and other income: Net interest expense and other income increased by $1 million for the 2010 Third Quarter compared to the same period last year. A debt retirement charge of $5 million related to the redemption of our 61/8% senior subordinated notes due 2013 was partially offset by lower interest expense as a result of lower outstanding debt.

Net interest expense and other income increased by $12 million for the 2010 Year-to-Date Period compared to the same period last year primarily due to debt retirement charges of $18 million related to our redemption of the Subordinated Notes. This increase was partially offset by higher income from investments accounted for using the equity method and lower interest expense as a result of lower outstanding debt.

Effective income tax rate: The effective tax rate for the 2010 Third Quarter increased by 670 basis points compared to the same quarter last year. The increase is primarily due to a tax benefit of $26 million, or $0.22 per diluted share, recorded in the 2009 Third Quarter for a net reversal of amounts previously accrued related to tax years for which the statute of limitations had expired.

The effective tax rate for the 2010 Year-to-Date Period increased by 290 basis points compared to the same period last year primarily due to the 2009 Third Quarter tax benefit of $26 million, discussed above, and the expiration of the U.S. Federal research and experimentation tax credit as of December 31, 2009. In addition, the 2010 Year-to-Date Period includes a tax provision of $5 million, or $0.04 per diluted share, related to the U.S. Federal Patient Protection and Affordable Care Act, which changed the tax treatment for certain retiree prescription drug benefits.

Net income attributable to L-3 and diluted earnings per share: Net income attributable to L-3 in the 2010 Third Quarter decreased by $12 million compared to the 2009 Third Quarter, and L-3 Holdings’ diluted earnings per share (diluted EPS) decreased to $2.07

31

from $2.12. As discussed above, the 2010 Third Quarter includes a debt retirement charge of $5 million, or $0.03 per diluted share, and the 2009 Third Quarter includes a tax benefit of $26 million, or $0.22 per diluted share.

Net income attributable to L-3 in the 2010 Year-to-Date Period increased by $13 million compared to the 2009 Year-to-Date Period, and L-3 Holdings’ diluted EPS increased by $0.21 or 4%, to $5.89 from $5.68. As discussed above, the 2010 Year-to-Date Period includes debt retirement charges of $18 million, or $0.09 per diluted share, and the 2009 Year-to-Date Period includes a tax benefit of $26 million, or $0.22 per diluted share.

Diluted weighted average common shares outstanding: Diluted weighted average common shares outstanding for the 2010 Third Quarter and 2010 Year-to-Date Period decreased by 2.3 million and 1.6 million shares compared to the same periods last year, respectively. The decrease in both periods was due to repurchases of our common stock in connection with our share repurchase program authorized by our Board of Directors, partially offset by additional shares issued in connection with various employee stock-based compensation programs and contributions to employee savings plans made in common stock.

Third Quarter: C³ISR net sales for the 2010 Third Quarter increased by 8% compared to the 2009 Third Quarter primarily due to demand for airborne ISR logistics support services and networked communication systems for manned and unmanned platforms to the DoD.

C³ISR operating income for the 2010 Third Quarter increased by 10% compared to the 2009 Third Quarter. Operating margin increased by 20 basis points. Improved contract performance was partially offset primarily by higher sales of lower margin logistics support services for airborne ISR platforms.

Year-to-Date: C³ISR net sales for the 2010 Year-to-Date Period increased by 8% compared to the 2009 Year-to-Date Period primarily due to increased demand and new business from the DoD for airborne ISR logistics support services and networked communications systems for manned and unmanned platforms and from foreign ministries of defense for force protection products.

C³ISR operating income for the 2010 Year-to-Date Period increased by 17% compared to the 2009 Year-to-Date Period. Operating margin increased by 90 basis points. Higher sales volume and improved contract performance increased operating margin by 80 basis points and lower pension expense of $4 million increased operating margin by 20 basis points. These increases were partially offset primarily by higher sales of lower margin logistics support services for airborne ISR platforms.

Third Quarter: Government Services net sales for the 2010 Third Quarter increased by 1% compared to the 2009 Third Quarter. The increase was due to: (1) $27 million in higher sales primarily for increased logistics, training and law enforcement support services for the U.S. Army due to higher volume on new and existing contracts, and (2) $15 million in higher sales for information technology support services for the U.S. Special Operations Command (SOCOM) and other U.S. Government agencies. These increases were partially offset by reduced subcontractor pass-through sales volume of $31 million related to task order renewals for U.S. Army SSES services that migrated to a contract where L-3 is not a prime contractor and $4 million of lower sales related to Iraq support.

Government Services operating income for the 2010 Third Quarter decreased by 9% compared to the 2009 Third Quarter. Operating margin decreased by 100 basis points. Operating margin was reduced by 130 basis points primarily due to lower margins on select contract renewals due to competitive price pressures and a favorable contract closeout in the prior year. These decreases were partially offset by a decline in lower margin subcontractor pass-through sales, which increased operating margin by 30 basis points.

Year-to-Date: Government Services net sales for the 2010 Year-to-Date Period decreased by 3% compared to the 2009 Year-to-Date Period. The decrease was primarily due to: (1) reduced subcontractor pass-through sales volume of $117 million related to SSES services, and (2) $66 million in lower sales related to Iraq support. These decreases were partially offset by $69 million in higher sales primarily for increased logistics, training and law enforcement support services for the U.S. Army due to higher volume on new and existing contracts, and information technology support services for SOCOM and other U.S. Government agencies. The increase in net sales from acquired businesses was $13 million.

Government Services operating income for the 2010 Year-to-Date Period decreased by 13% compared to the 2009 Year-to-Date Period. Operating margin decreased by 100 basis points. Operating margin was reduced by 130 basis points primarily due to lower margins on select contract renewals, higher costs for a security systems contract for the U.S. Department of Homeland Security and the timing of award fees. These decreases were partially offset by a decline in lower margin subcontractor pass-through sales, which increased operating margin by 30 basis points.

Third Quarter: AM&M net sales for the 2010 Third Quarter decreased by 5% compared to the 2009 Third Quarter. The decrease was primarily due to sales volume declines for: (1) systems field support services for U.S. Air Force fixed wing training aircraft of $31 million, (2) JCA and CFS of $28 million, (3) a competitive loss of an aircraft maintenance contract with the US. Customs and Border Patrol of $13 million, (4) an aircraft modernization contract nearing completion for a foreign customer of $9 million, and (5) the SOFSA contract of $7 million because of reduced tasking. These decreases were partially offset by $53 million in higher aircraft modernization sales primarily for special mission aircraft and rotary wing cabin assemblies and higher demand from existing contracts for systems field support services for U.S. Army rotary wing training aircraft.

AM&M operating income for the 2010 Third Quarter decreased by 19% compared to the 2009 Third Quarter. Operating margin decreased by 130 basis points. The decrease in operating margin was primarily due to lower sales volume for CFS, systems field support services to the U.S. Air Force, and aircraft modernization due to a contract nearing completion for a foreign customer.

Year-to-Date: AM&M net sales for the 2010 Year-to-Date Period increased by 1% compared to the 2009 Year-to-Date Period. The increase was primarily due to higher sales volume for: (1) aircraft modernization, primarily for U.S. Navy maritime patrol aircraft, special mission aircraft, and rotary wing cabin assemblies of $76 million, (2) JCA of $49 million, and (3) systems field support services for U.S. Army rotary wing training aircraft of $31 million. These increases were partially offset primarily by $137 million in sales volume declines for CFS and the SOFSA contract because of reduced tasking, a competitive loss of an aircraft maintenance contract with the U.S. Customs and Border Patrol, decreased volume for systems field support services for U.S. Air Force fixed wing training aircraft, and an aircraft modernization contract nearing completion for a foreign customer.

AM&M operating income for the 2010 Year-to-Date Period decreased by 7% compared to the 2009 Year-to-Date Period. Operating margin decreased by 70 basis points. The decrease in operating margin was primarily due to lower systems field support services to the U.S. Air Force, and lower margin sales mix, primarily related to higher JCA volume, which has lower margins than the overall AM&M reportable segment.

Third Quarter: Electronic Systems net sales for the 2010 Third Quarter decreased by 3% compared to the 2009 Third Quarter. Sales volume declined by: (1) $28 million for commercial shipbuilding products as a result of reduced demand, (2) $27 million for combat propulsion systems due to a reduction in DoD funding for the Bradley fighting vehicle, and (3) $54 million for precision engagement and marine services due to contracts nearing completion. These decreases were partially offset primarily by volume increases of $14 million due to higher demand for EO/IR products to the U.S. Army, and security & detection systems due to deliveries of ProVision^tm systems. The increase in net sales from acquired businesses was $60 million, primarily related to the acquisition of Insight.

Electronic Systems operating income for the 2010 Third Quarter increased by 20% compared to the 2009 Third Quarter. Operating margin increased by 280 basis points. The increase was due to favorable sales mix across several businesses, primarily for EO/IR

products and microwave products. A favorable contract modification for precision engagement increased operating income by $5 million and operating margin by 50 basis points. In addition, lower pension expense of $1 million increased operating margin by 10 basis points.

Year-to-Date: Electronic Systems net sales for the 2010 Year-to-Date Period decreased by 2% compared to the 2009 Year-to-Date Period. Sales volume declined by: (1) $84 million for combat propulsion systems due to a reduction in DoD funding for the Bradley fighting vehicle, (2) $73 million for commercial shipbuilding products, and (3) $114 million for precision engagement, marine services, training & simulation and displays due to contracts nearing completion. These decreases were partially offset by volume increases of $71 million due to higher demand primarily for EO/IR products to the U.S. Army, microwave products mainly due to deliveries of power devices for satellite communication systems, and security & detection systems due to deliveries of ProVision^tm systems. The increase in net sales from acquired businesses was $114 million, primarily related to the acquisition of Insight.

Electronic Systems operating income for the 2010 Year-to-Date Period increased by 18% compared to the 2009 Year-to-Date Period. Operating margin increased by 250 basis points. The increase was due to favorable sales mix across several businesses, primarily EO/IR products. A favorable contract modification for precision engagement increased operating income by $5 million and operating margin by 20 basis points. In addition, lower pension expense of $7 million increased operating margin by 20 basis points.

Liquidity and Capital Resources

Anticipated Sources and Uses of Cash Flow

Our primary source of liquidity is cash flow generated from operations. As of September 24, 2010, we also had, subject to certain conditions, $973 million of borrowings available under our $1 billion Revolving Credit Facility, after reductions of $27 million for outstanding letters of credit. Our $1 billion Revolving Credit Facility expires on October 23, 2012. We currently believe that our cash from operating activities together with our cash on hand and available borrowings under our Revolving Credit Facility will be adequate for the foreseeable future to meet our anticipated requirements for working capital, capital expenditures, defined benefit plan contributions, commitments, contingencies, research and development expenditures, business acquisitions (depending on the size), contingent purchase price payments on previous business acquisitions, program and other discretionary investments, interest payments, income tax payments, L-3 Holdings’ dividends and share repurchases, and potential debt repurchases. Holders of our $700 million Convertible Contingent Debt Securities (CODES) may require us to repurchase them in whole or in part at a cash repurchase price equal to 100% of the principal amount (plus accrued and unpaid interest, including contingent interest and additional interest, if any) through the exercise of a “put” option on February 1, 2011. In such an event, we intend to either complete a refinancing of all or a portion of the CODES, if we have the ability to do so on terms and conditions acceptable to us, or repurchase any amount of the CODES put to L-3 with cash on hand and revolving credit borrowings, if necessary. The next scheduled maturity of our existing debt is our $650 million 57/8% Senior Subordinated Notes maturing on January 15, 2015.

Our business may not continue to generate cash flow at current levels, and it is possible that currently anticipated improvements may not be achieved. If we are unable to generate sufficient cash flow from operations to service our debt, we may be required to reduce costs and expenses, sell assets, reduce capital expenditures, refinance all or a portion of our existing debt or obtain additional financing and we may not be able to do so on a timely basis, on satisfactory terms, or at all. Our ability to make scheduled principal payments or to pay interest on or to refinance our indebtedness depends on our future performance and financial results, which, to a certain extent, are subject to general conditions in or affecting the U.S. defense industry and to general economic, political, financial, competitive, legislative and regulatory factors beyond our control.

For a discussion of our recent debt issuance and repayments in the second and third quarters of 2010, which improved our debt maturity profile and reduced our cost of capital, see “Financing Activities — Debt” on page 37.

Balance Sheet

Billed receivables increased by $116 million to $1,265 million at September 24, 2010, from $1,149 million at December 31, 2009 primarily due to: (1) the timing of billings and collections primarily for government services and ISR services, (2) higher sales primarily for EO/IR products to the U.S. Army, and (3) $31 million of acquired billed receivables from business acquisitions. These increases were partially offset by decreases for secure communications and displays due to collections and lower sales and $4 million for foreign currency translation adjustments.

35

Contracts in process increased by $172 million to $2,567 million at September 24, 2010, from $2,395 million at December 31, 2009. The increase included $6 million for acquired contracts-in-process, a $3 million reclassification from property, plant and equipment to inventoried contract costs and a $163 million increase from:

•   Increases of $51 million in unbilled contract receivables primarily due to sales exceeding billings for aircraft modernization and networked communications systems, partially offset by decreases due to billings for government services; and

•   Increases of $112 million in inventoried contract costs across several business areas, primarily fuzing and ordnance, networked communications systems, EO/IR products and displays to support current and anticipated customer demand.

L-3’s receivables days sales outstanding (DSO) was 69 at September 24, 2010, compared with 66 at December 31, 2009 and 70 at September 25, 2009. We calculate our DSO by dividing: (1) our aggregate end of period billed receivables and net unbilled contract receivables, by (2) our trailing 12 month sales adjusted, on a pro forma basis, to include sales from business acquisitions and exclude sales from business divestitures that we completed as of the end of the period, multiplied by the number of calendar days in the trailing 12 month period (364 days at September 24, 2010, 365 days at December 31, 2009 and 364 days at September 25, 2009). Our trailing 12 month pro forma sales were $15,816 million at September 24, 2010, $15,621 million at December 31, 2009 and $15,492 million at September 25, 2009.

The increase in inventories was primarily due to $49 million of acquired inventories from business acquisitions and higher inventory for security and detection systems to support customer demand. These increases were partially offset by a decrease of $5 million for foreign currency translation adjustments.

The decrease in current deferred income tax assets was due to Internal Revenue Service tax accounting method changes we elected regarding compensation expense and income recognition of service contracts during the 2010 Year-to-Date Period.

The increase in net property, plant and equipment (PP&E) was principally due to capital expenditures and $60 million of acquired PP&E from completed business acquisitions, partially offset by depreciation expense.

Goodwill increased by $500 million to $8,690 million at September 24, 2010 from $8,190 million at December 31, 2009. The table below presents the changes in goodwill applicable to our reporting units in each reportable segment.

(1)	Represents the acquisition of Insight, Airborne Technologies, Inc., and 3Di Technologies, LLC. For further discussion regarding business acquisitions, see Note 4 to our unaudited condensed consolidated financial statements contained in this quarterly report.
(2)	The net decrease in goodwill from foreign currency translation adjustments is primarily due to the strengthening of the U.S. dollar against the Euro during the 2010 Year-to-Date Period.
(3)	As a result of a re-alignment of a business unit in our management and organizational structure as discussed in Note 2 to our unaudited condensed consolidated financial statements contained in this quarterly report, goodwill was reclassified on a relative fair value basis from Government Services to Electronic Systems during the second quarter of 2010.

The increase in identifiable intangible assets was primarily due to the recognition of $133 million of intangible assets for the business acquisitions during the 2010 Year-to-Date Period, partially offset by amortization expense.

The increase in accounts payable was primarily due to the timing of when invoices were received and payments were made. The increase in accrued employment costs was primarily due to the timing of payments for payroll taxes, employee benefits, and salaries and wages.

The decrease in pension and postretirement benefit plan liabilities was primarily due to cash contributions exceeding pension expense (excluding amortization of net losses) during the 2010 Year-to-Date Period. We expect to contribute cash of approximately $135 million to our pension plans for all of 2010, of which $115 million was contributed during the 2010 Year-to-Date Period.

Non-current deferred income tax liabilities increased primarily due to amortization of certain goodwill and other identifiable intangible assets for tax purposes.

Statement of Cash Flows

2010 Year-to-Date Period Compared with 2009 Year-to-Date Period

The table below provides a summary of our cash flows from operating, investing, and financing activities for the periods indicated.

	Year-to-Date Ended
	September 24,			September 25,
	2010			2009
	(in millions)
Net cash from operating activities	$	984		$	978
Net cash used in investing activities		(819	)		(211	)
Net cash used in financing activities		(522	)		(464	)

Operating Activities

We generated $984 million of cash from operating activities during the 2010 Year-to-Date Period, an increase of $6 million compared with $978 million generated during the 2009 Year-to-Date Period. The increase was due to: (1) an increase in net income of $13 million, and (2) higher non-cash expenses of $23 million primarily due to higher deferred income taxes and stock-based employee compensation expense. These increases were partially offset by $30 million of more net cash used for changes in operating assets and liabilities primarily for billed receivables, contracts in process and pension and post retirement benefits, partially offset by less cash used for accrued employment costs and income taxes. The net cash used for changes in operating assets and liabilities is further discussed above under “Liquidity and Capital Resources — Balance Sheet” beginning on page 35.

Investing Activities

During the 2010 Year-to-Date Period, we used $819 million of cash in the aggregate primarily to: (1) acquire three businesses, (2) pay $98 million for capital expenditures, and (3) invest $20 million in an unconsolidated subsidiary accounted for using the equity method.

Financing Activities

Debt

At September 24, 2010, total outstanding debt was $4,132 million, of which $1,794 million was senior debt and $2,338 million was subordinated debt and CODES, compared to $4,112 million at December 31, 2009, of which $996 million was senior debt and $3,116 million was subordinated debt and CODES. At September 24, 2010, subject to certain conditions, borrowings available under our Revolving Credit Facility were $973 million, after reduction for outstanding letters of credit of $27 million. There were no borrowings outstanding under our Revolving Credit Facility at September 24, 2010. Our Revolving Credit Facility expires on October 23, 2012.

On May 21, 2010, L-3 Communications issued $800 million in principal amount of 4.75% Senior Notes that mature on July 15, 2020 (2020 Senior Notes) at a discount of $3 million. The effective interest rate of the 2020 Senior Notes is 4.79%. Interest on the 2020 Senior Notes is payable semi-annually on January 15 and July 15 of each year, commencing on January 15, 2011. The net cash proceeds from this offering amounted to approximately $790 million after deducting the discounts, commissions and estimated expenses, and were used, together with cash on hand, to redeem L-3 Communications’ Subordinated Notes. In connection with the redemption of the Subordinated Notes, we recorded debt retirement charges of approximately $13 million ($8 million after income tax, or $0.07 per diluted share) during the second quarter of 2010 and $5 million ($3 million after income tax, or $0.03 per diluted share) during the 2010 Third Quarter.

Our outstanding debt has scheduled maturities between January 15, 2015 and August 1, 2035. In addition, holders of our CODES may require us to repurchase them in whole or in part at a cash price equal to 100% of the principal amount (plus accrued and unpaid interest, including contingent interest and additional interest, if any) through the exercise of a “put” option on February 1, 2011. As a result, the CODES have been classified as a current liability at September 24, 2010. See Note 9 to our unaudited condensed consolidated financial statements contained in this quarterly report for the components of our current and long-term debt at September 24, 2010.

Debt Covenants and Other Provisions. The Revolving Credit Facility, senior notes and senior subordinated notes contain financial and/or other restrictive covenants. See Note 10 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for a description of our debt and related financial covenants, including dividend

37

payment and share repurchase restrictions and cross default provisions. As of September 24, 2010, we were in compliance with our financial and other restrictive covenants.

Under select conditions, including if L-3 Holdings’ common stock price is more than 120% (currently $118.73) of the then current conversion price ($98.94 as of May 14, 2010) for a specified period, the conversion feature of the CODES will require L-3 Holdings, upon conversion, to pay the $700 million principal amount in cash, and if the settlement amount exceeds the principal amount, the excess will be settled in cash or stock or a combination thereof, at our option. See Note 10 to our audited consolidated financial statements for the year ended December 31, 2009, included in our Annual Report on Form 10-K, for additional information regarding the CODES, including conditions for conversion. L-3 Holdings’ closing stock price on November 1, 2010 was $72.69 per share.

Guarantees. The borrowings under the Revolving Credit Facility are fully and unconditionally guaranteed by L-3 Holdings and by substantially all of the material wholly-owned domestic subsidiaries of L-3 Communications on an unsecured senior basis. The payment of principal and premium, if any, and interest on the senior notes are fully and unconditionally guaranteed, on an unsecured senior basis, jointly and severally, by L-3 Communications’ material wholly-owned domestic subsidiaries that guarantee any of our other indebtedness. The payment of principal and premium, if any, and interest on the senior subordinated notes are fully and unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by L-3 Communications’ wholly-owned domestic subsidiaries that guarantee any of our other indebtedness. The payment of principal and premium, if any, and interest on the CODES are fully and unconditionally guaranteed, on an unsecured senior subordinated basis, jointly and severally, by L-3 Communications and its wholly-owned domestic subsidiaries that guarantee any of our other liabilities.

Subordination. The guarantees of the Revolving Credit Facility and the senior notes rank senior to the guarantees of the senior subordinated notes and the CODES and rank pari passu with each other. The guarantees of the senior subordinated notes and CODES rank pari passu with each other and are junior to the guarantees of the Revolving Credit Facility and senior notes.

Forward-Looking Statements

Certain of the matters discussed concerning our operations, cash flows, financial position, economic performance and financial condition, including in particular, the likelihood of our success in developing and expanding our business and the realization of sales from backlog, include forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act.

Statements that are predictive in nature, that depend upon or refer to events or conditions or that include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates” and similar expressions are forward-looking statements. Although we believe that these statements are based upon reasonable assumptions, including projections of total sales growth, sales growth from business acquisitions, organic sales growth, consolidated operating margins, total segment operating margins, interest expense, earnings, cash flow, research and development costs, working capital, capital expenditures and other projections, they are subject to several risks and uncertainties, and therefore, it is possible that these statements may not be achieved. Such statements will also be influenced by factors which include, among other things:

•  our dependence on the defense industry and the business risks peculiar to that industry, including changing priorities or reductions in the U.S. Government defense budget;

•  our reliance on contracts with a limited number of agencies of, or contractors to, the U.S. Government and the possibility of termination of government contracts by unilateral government action or for failure to perform;

•  the extensive legal and regulatory requirements surrounding our contracts with the U.S. or foreign governments and the results of any investigation of our contracts undertaken by the U.S. or foreign governments, including potential suspensions or debarments;

•  our ability to retain our existing business and related contracts (revenue arrangements);

•  our ability to successfully compete for and win new business and related contracts (revenue arrangements) and to win re-competitions of our existing contracts;

•  our ability to identify and acquire additional businesses in the future with terms, including the purchase price, that are attractive to L-3 and to integrate acquired business operations;

•  our ability to maintain and improve our consolidated operating margin and total segment operating margin in future periods;

•  our ability to obtain future government contracts (revenue arrangements) on a timely basis;

•  the availability of government funding or cost-cutting initiatives and changes in customer requirements for our products and services;

•  our significant amount of debt and the restrictions contained in our debt agreements;

•  our ability to continue to retain and train our existing employees and to recruit and hire new qualified and skilled employees, as well as our ability to retain and hire employees with U.S. Government security clearances that are a prerequisite to compete for and to perform work on classified contracts for the U.S. Government;

•  actual future interest rates, volatility and other assumptions used in the determination of pension benefits and equity-based compensation, as well as the market performance of benefit plan assets;

•  our collective bargaining agreements, our ability to successfully negotiate contracts with labor unions and our ability to favorably resolve labor disputes should they arise;

•  the business, economic and political conditions in the markets in which we operate, including those for the commercial aviation, shipbuilding and communications markets;

•  global economic uncertainty;

•  the DoD’s contractor support services in-sourcing initiative;

•  events beyond our control such as acts of terrorism;

•  our ability to perform contracts (revenue arrangements) on schedule;

•  our international operations, including sales to foreign customers;

39

•  our extensive use of fixed-price type contracts as compared to cost-plus type and time-and-material type contracts;

•  the rapid change of technology and high level of competition in the defense industry and the commercial industries in which our businesses participate;

•  our introduction of new products into commercial markets or our investments in civil and commercial products or companies;

•  the outcome of current or future litigation matters, including those that are expected to be resolved by jury trials, which are inherently risky and for which outcomes are difficult to predict;

•  results of audits by U.S. Government agencies, including the Defense Contract Audit Agency, of our sell prices, costs and performance on contracts (revenue arrangements), and our accounting and general business practices;

•  the impact on our business of improper conduct by our employees, agents or business partners;

•  anticipated cost savings from business acquisitions not fully realized or realized within the expected time frame;

•  the outcome of matters relating to the Foreign Corrupt Practices Act (FCPA);

•  ultimate resolution of contingent matters, claims and investigations relating to acquired businesses, and the impact on the final purchase price allocations;

•  significant increases in competitive pressure among companies in our industry; and

•  the fair values of our assets, including identifiable intangible assets and the estimated fair value of the goodwill balances for our reporting units, which can be impaired or reduced by other factors, some of which are discussed above.

In addition, for a discussion of other risks and uncertainties that could impair our results of operations or financial condition, see “Part I — Item 1A — Risk Factors” and Note 19 to our audited consolidated financial statements, in each case included in our Annual Report on Form 10-K for the year ended December 31, 2009.

Readers of this document are cautioned that our forward-looking statements are not guarantees of future performance and the actual results or developments may differ materially from the expectations expressed in the forward-looking statements.

As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Given these uncertainties, you should not place any reliance on these forward-looking statements. These forward-looking statements also represent our estimates and assumptions only as of the date that they were made. We expressly disclaim a duty to provide updates to these forward-looking statements, and the estimates and assumptions associated with them, after the date of this filing to reflect events or changes in circumstances or changes in expectations or the occurrence of anticipated events.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Derivative Financial Instruments,” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 for a discussion of our exposure to market risks. There were no material changes in those risks during the 2010 Year-to-Date Period. See Notes 15 and 16 to our unaudited condensed consolidated financial statements contained in this quarterly report for the aggregate fair values and notional amounts of our foreign currency forward contracts at September 24, 2010.

ITEM 4.

CONTROLS AND PROCEDURES

Conclusions Regarding Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934 related to L-3 Holdings and L-3 Communications is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s (SEC) rules and forms, and that such information is accumulated and communicated to our management, including our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Our management, with the participation of our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of September 24, 2010. Based upon that evaluation and subject to the foregoing, our Chairman, President and Chief Executive Officer, and our Senior Vice President and Chief Financial Officer concluded that, as of September 24, 2010, the design and operation of our disclosure controls and procedures were effective to accomplish their objectives at the reasonable assurance level.

There were no changes in our internal control over financial reporting that occurred during the quarter ended September 24, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1.

LEGAL PROCEEDINGS

The information required with respect to this item can be found in Note 17 to our unaudited condensed consolidated financial statements contained in this quarterly report and is incorporated by reference into this Item 1.

ITEM 1A.

RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2009, and as updated below, which could materially affect our business, financial condition or future results. The risks described in this report and in our Annual Report on Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Our contracts (revenue arrangements) with U.S. Government customers entail certain risks

The DoD’s wide-ranging Efficiencies Initiative, which targets affordability and cost growth, could have a material effect on the procurement process and may adversely affect our existing contracts and the awards of new contracts.

The U.S. Government has issued guidance regarding changes to the procurement process that is intended to control cost growth throughout the acquisition cycle by developing a competitive strategy for each program. As a result, the Company expects to engage in more frequent negotiations and re-competitions on a cost or price analysis basis with every competitive bid in which it participates. These initiatives are organized into five major areas: affordability and cost growth; productivity and innovation; competition; services acquisition; and, processes and bureaucracy. Because this initiative significantly changes the way the U.S. Government solicits, negotiates and manages its contracts, this initiative could result in a reduction in expenditures for the type of products we manufacture and services we provide to the U.S. Government and could have a material negative impact on our future sales, earnings and cash flows.
