REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 

To the Benefit Plan Administrative Committee of the

Northrop Grumman PEI Retirement Savings Plan

 

We have audited the accompanying statements of net assets available for benefits of the Northrop Grumman PEI Retirement Savings Plan (the “Plan”) as of December 31, 2005 and 2004, and the related statement of changes in net assets available for benefits for the year ended December 31, 2005. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

 

In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for the year ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America.

 

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2005 is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This schedule is the responsibility of the Plan’s management. Such schedule has been subjected to the auditing procedures applied in our audit of the basic 2005 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

NORTHROP GRUMMAN PEI RETIREMENT SAVINGS PLAN

 

NOTES TO FINANCIAL STATEMENTS

AS OF DECEMBER 31, 2005 AND 2004, AND FOR THE YEAR ENDED DECEMBER 31, 2005


 

1. DESCRIPTION OF THE PLAN

 

The following description of the Northrop Grumman PEI Retirement Savings Plan (the “Plan”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

 

General — The Plan is a qualified profit-sharing plan sponsored by the Productos Electronicos Industriales division of Northrop Grumman Electronicos, Inc. (the “Company”). The Plan includes a 401(k) feature and employer matching contributions. Both the savings and employee stock ownership features are reported within the Plan’s 2005 financial statements.

 

The Plan was established by the Company on March 1, 1996, as a successor to the Westinghouse de Puerto Rico Retirement Savings Plan (the “Predecessor Plan”), maintained by Westinghouse de Puerto Rico, Inc. for the benefit of Puerto Rican employees of certain Westinghouse Electric Corporation affiliated companies who became employees of the Company, and any other subsequent eligible employees of the Company. The Benefit Plan Administrative Committee of Northrop Grumman Corporation (“NGC”) controls and manages the operation and administration of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

 

Plan assets are invested 100 percent in the Northrop Grumman Corporation PEI Pension and 401(k) Plans Master Trust (the “PEI Master Trust”), which is administered by Banco Popular de Puerto Rico (the “PEI Trustee”). The PEI Master Trust, in turn, has invested 100 percent of the Plan’s assets in the Northrop Grumman Defined Contribution Plans Master Trust (the “DC Master Trust”) which is administered by State Street Bank and Trust Company (“State Street”). As an agent to the PEI Trustee, State Street is responsible for tracking the individual assets and reporting month-end plan accounting to the PEI Trustee.

 

Contributions — Plan participants may contribute between 1 percent and 8 percent of total compensation, in increments of 1 percent on a pre-tax basis through payroll withholdings. Basic contributions may be made in amounts of 1 percent to 4 percent of total compensation. Eligible employees who have authorized the maximum basic contribution may make Supplementary contributions in amounts between 1 percent and 4 percent of total compensation. Contributions are subject to certain limitations imposed by the Internal Revenue Code of 1986, as amended (the “Code”).

 

The Company contributes a match of 50 percent of the amount of a participant’s Basic contribution. The maximum matching contribution will not exceed 2 percent of the total compensation of the participant.

 

An eligible employee may rollover any amount from another qualified plan or from an Individual Retirement Account into the Plan, provided that such rollover amount is paid to the PEI Trustee within 60 days of the date the employee received the qualifying rollover distribution.

 

Participant Accounts — A separate account is maintained for each participant, each of which has two subaccounts. Basic and Supplementary contributions are allocated to the participant’s

Table of Contents

contribution account. Company matching contributions are allocated to the participant’s Company matching contribution account. Assets of the DC Master Trust are valued at the end of each month, and on a daily basis, and take into account earnings and losses of the Plan along with appreciation or depreciation, expenses and distributions. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

 

Vesting — Plan participants are vested immediately in, and have a nonforfeitable right to, the balance of their Basic and Supplementary contributions at all times. Plan participants become 100 percent vested in Company contributions after three years of service and have no vesting prior to that time. Company contributions become 100 percent vested upon the attainment of age 65 or the death of a participant. Rollovers are 100 percent vested at all times and are not subject to forfeiture.

 

Investment Options — Upon enrollment in the Plan, each participant directs his or her contributions, including employer matching contributions, to be invested in any of the following investment funds within the DC Master Trust:

 

Northrop Grumman Fund — The Northrop Grumman Fund (“NG Stock Fund”) invests primarily in Northrop Grumman Corporation common stock.

 

U.S. Equity Fund — The U.S. Equity Fund consists predominantly of holdings in large and medium sized U.S. company stocks. The fund’s objectives are capital appreciation over the long term, along with current income (dividends). The fund’s stock investments are selected by independent professional investment managers appointed by the Plan’s Investment Committee.

 

Money Market Fund — The Money Market Fund invests in the Northrop Grumman Stable Value Fund (the “Stable Value Fund”, see Notes 5 and 6). Investments of the Stable Value Fund are diversified among U.S. Government securities and obligations of government agencies, bonds, short-term investments, cash and investment contracts issued by insurance companies and banks. The Stable Value Fund is managed by an independent professional investment manager appointed by the Plan’s Investment Committee.

 

U.S. Bond Fund — The U.S. Bond Fund consists of holdings in marketable, fixed income securities rated within the three highest investment grades assigned by Moody’s Investor Services or Standard & Poor’s Corporation, U.S. Treasury or federal agency obligations, or cash equivalent instruments. The fund is broadly diversified and maintains an average maturity of 10 years. The securities are selected by independent professional investment managers appointed by the Plan’s Investment Committee.

 

Payment of Benefits — All withdrawals from the Plan during employment shall be paid in cash. All distributions from the Plan upon retirement, termination or death shall be paid in cash and/or shares of Northrop Grumman Corporation common stock held in the account. A participating employee may elect to withdraw all or a portion of the vested portion of the participant account only in the case of hardship, as defined by the Plan, and may make withdrawals twice per year but not more than once per month. If a participating employee retires or employment is terminated, the vested portion of the participant account shall be distributed to the participant as soon as practicable following the next valuation date after retirement or termination occurs. Any

Table of Contents

nonvested portion of the participant account shall be forfeited at that time. In the case of death of a participating employee, the entire account shall be distributed in a lump sum to the participant’s beneficiary(ies).

 

Forfeited Accounts — Any amounts forfeited shall be used to reduce the Company’s obligation to make company matching contributions under the Plan. In 2005, insignificant employer contributions totaling $85 were reduced by forfeited nonvested amounts.

 

2. SIGNIFICANT ACCOUNTING POLICIES

 

Basis of Accounting — The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America.

 

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

 

Risk and Uncertainties — The Plan utilizes various securities, including U.S. Government securities, corporate debt instruments and corporate stocks. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities may occur in the near term, and that such changes could materially affect the amounts reported in the financial statements.

 

Investment Valuation and Income Recognition — The Plan’s investments in the PEI Master Trust (which in turn invests in the DC Master Trust) are stated at fair value as determined by State Street. The PEI Trustee relies on the prices provided by State Street in performing any valuations or calculations required of the PEI Trustee. The underlying investment in the PEI Master Trust is valued as follows:

 

Investments in common and preferred stock are valued at the last reported sales price of the stock on the last business day of the plan year. The shares of registered investment companies are valued at quoted market prices that represent the net asset values of shares held by the Plan at year end. Investments in common trust funds are valued based on the redemption price of units owned by the Plan, which is based on the current fair value of the funds underlying assets. Fair values for securities are based on information in financial publications of general circulation, statistical and valuation services, records of security exchanges, appraisals by qualified persons, transactions and bona fide offers in assets of the type in question and other information customarily used in the valuation of assets or if market values are not available, at their fair values as provided to State Street by the party with authority to trade in such securities (investment managers or the Plan’s Investment Committee, as applicable).

 

Guaranteed investment contracts held by the Plan through the Stable Value Fund are considered to be fully benefit-responsive and therefore are recorded at contract value. Contract value represents contributions made under the contract, plus interest at the contract rate, less withdrawals and contract administrative expenses. Contract value approximates fair value. In addition, the Plan entered into synthetic investment contracts in order to manage the market risk and return of certain securities held by the Plan (see Notes 5 and 6).

Table of Contents

All securities and cash or cash equivalents are quoted in the local currency and then converted into U.S. dollars using the appropriate exchange rate obtained by State Street. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Broker commissions, transfer taxes, and other charges and expenses incurred in connection with the purchase, sale, or other disposition of securities or other investments are added to the cost of such securities or other investments, or are deducted from the proceeds of the sale or other disposition thereof, as appropriate. Taxes, if any, on the assets of the funds, or on any gain resulting from the sale or other disposition of such assets, or on the earnings of the funds, are apportioned among the participants whose interests in the Plan are affected, and the share of such taxes apportioned to each such person is charged against his or her account in the Plan.

 

The PEI Master Trust and the DC Master Trust allocate investment income, realized gains and losses and unrealized appreciation and depreciation on the underlying securities to the participating plans monthly and daily, respectively, based on the market value of each plan’s investment. The unrealized appreciation or depreciation in the aggregate current value of investments is the difference between current value and the cost of investments. The realized gain or loss on investments is the difference between the proceeds received and the average cost of the investments sold.

 

Administrative Expenses — Administrative expenses of the Plan are paid by the Company.

 

Payment of Benefits — Payments to participants are recorded upon distribution. Amounts allocated to accounts of participants who have elected to withdraw from the Plan but have not yet been paid were $7,189 and $2,653 at December 31, 2005 and 2004, respectively, and such amounts continue to accrue interest until paid.

 

Reclassification — Certain prior year amounts have been reclassified to conform to the current year presentation.

 

3. INVESTMENTS

 

PEI Master Trust — The investments of the Plan as of December 31, 2005 and 2004 are stated at fair values reported by the PEI Trustee.

Plan assets represented 46 percent and 48 percent of total PEI Master Trust net assets reported by the PEI Trustee as of December 31, 2005 and 2004, respectively. The Plan’s interest in the PEI Master Trust did not include any interest in the PEI Master Trust’s investment in the Northrop Grumman Employee Benefit Plan Master Trust as of December 31, 2005 and 2004, and for the year ended December 31, 2005

4. DERIVATIVE FINANCIAL INSTRUMENTS

 

Derivative financial instruments may be used by the investment managers of the DC Master Trust as part of their respective strategies. These strategies include the use of futures contracts, interest rate swaps, options on futures and options as substitutes for certain types of securities. Notional amounts disclosed below do not quantify risk or represent assets or liabilities of the DC Master Trust, but are used in the calculation of the cash settlements under the contracts.

 

The fair value of these instruments is recorded as investments of the DC Master Trust. To the extent that a gain has been recognized, these instruments are recorded as assets and to the extent that a loss has been recognized, these instruments are recorded as a liability.

Table of Contents

Futures Contracts — The DC Master Trust enters into futures contracts in the normal course of investing activities to manage market risk associated with equity and fixed income investments and to achieve overall investment portfolio objectives. These contracts involve elements of market risk in excess of amounts recognized in the statements of net assets available for plan benefits. The credit risk associated with these contracts is minimal as they are traded on organized exchanges and settled daily. The terms of these contracts typically do not exceed one year. Notional amounts related to these contracts in the table above are stated as a net buy (sell) position.

 

Interest Rate Swaps — The DC Master Trust enters into interest rate swap contracts in the normal course of its investing activities to manage the interest rate exposure associated with fixed income investments. The credit risk associated with these contracts is minimal as they are entered into with a limited number of highly rated counterparties.

 

Options on Futures and Swaps — The DC Master Trust enters into contracts in the normal course of its investing activities to manage the interest rate exposure associated with fixed income investments.

5. INTEREST IN NORTHROP GRUMMAN STABLE VALUE FUND

 

The Plan’s investment in the PEI Master Trust through its investment in the DC Master Trust includes amounts in the Northrop Grumman Stable Value Fund, established for the investment of the assets of certain savings plans sponsored by NGC and its affiliates. Each participating savings plan has an undivided interest in the Stable Value Fund. At December 31, 2005 and 2004, the Plan’s interests in the net assets of the Stable Value Fund were .04 percent and .03 percent, respectively, of the total fund value. Investment income and administrative expenses relating to the Stable Value Fund are allocated among the participating plans on a daily basis.

 

Investments held in the Stable Value Fund as of December 31, 2005 and 2004 were as follows:

 

     2005

   2004

Guaranteed and synthetic investment contracts (at contract value)

   $ 2,915,422,961    $ 2,726,708,728

The Stable Value Fund holds wrapper contracts in order to manage the market risk and return of certain securities held by the Stable Value Fund. The wrapper contracts generally modify the investment characteristics of certain underlying securities similar to those of guaranteed investment contracts. Each wrapper contract and its related underlying assets is referred to as a synthetic investment contract (“SIC”) and is recorded at contract value.

 

The fair value of the underlying assets related to the SICs was $2,898,864,923 and $2,760,543,569 as of December 31, 2005 and 2004, respectively. The fair value of non-synthetic contracts held by the Plan approximated their contract value as of December 31, 2004. The weighted average yield (excluding administrative expenses) for all investment contracts was 4.88 percent and 4.74 percent at December 31, 2005 and 2004, respectively. Average duration for all investment contracts was 3.19 years and 2.91 years at December 31, 2005 and 2004, respectively. The crediting interest rate for all investment contracts was 4.86 percent and 4.74 percent at December 31, 2005 and 2004, respectively. Crediting interest rates are reset on a quarterly basis. Resets are determined based upon the market-to-book ratio, along with the yield and duration of the underlying investments.

 

7. EXEMPT PARTY-IN-INTEREST TRANSACTIONS

 

Party-in-interest transactions include the purchase and sale of investments managed by affiliates, transactions involving common stock of NGC, and payments made by the Company or NGC for certain Plan administrative costs. The Plan held 1,128 shares and 570 shares with fair value of $67,811 and $52,425 of common stock of NGC at December 31, 2005, and 2004, respectively. The Plan received dividends of $849 from its investment in NGC common stock during the year ended December 31, 2005.

 

The Plan had transactions with the PEI Trustee’s and State Street’s short-term investment funds, liquidity pooled funds in which participation commences and terminates on a daily basis.

 

The DC Master Trust utilized various investment managers to manage its net assets. These net assets may be invested into funds also managed by the investment managers. Therefore, these transactions qualify as party-in-interest transactions.

 

8. PLAN TERMINATION

 

Although it has not expressed any intention to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of the Plan’s termination, participants will become 100 percent vested in their accounts.

9. FEDERAL INCOME TAX STATUS

 

The Plan is intended to be qualified under the Code and the Puerto Rico Income Tax Code of 1994. The Plan obtained its latest determination letter dated December 11, 2000, in which the Internal Revenue Service determined that the Plan terms at the time of the determination letter application were in compliance with the applicable sections of the Code and, therefore, the related trust is exempt from taxation. The Plan has been amended since receiving the determination letter. Although the amendments have not yet been filed for a favorable determination letter, management will make any changes necessary to maintain the Plan’s tax-qualified status. However, management believes that the Plan and the related trust are designed and currently being operated in compliance with the applicable provisions of the Code and Puerto Rico Income Tax Code of 1994. Therefore, no provision for income taxes has been included in the Plan’s financial statements.
