RETIREMENT SAVINGS PLAN YEARS ENDED DECEMBER 31, 2005 AND 2004 -3- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Plan Sponsor Belden CDT Inc. Retirement Savings Plan We have audited the accompanying statements of net assets available for benefits of the Belden CDT Inc. Retirement Savings Plan as of December 31, 2005 and 2004, and the related statements of changes in net assets available for benefits for the years then ended. 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 audit. We conducted our audits in accordance with the auditing 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, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Belden CDT Inc. Retirement Savings Plan as of December 31, 2005 and 2004, and the changes in its net assets available for benefits for the years then ended 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) 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 supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 2005 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ Brown Smith Wallace, LLC June 16, 2006 -4- Belden CDT Inc.

Retirement Savings Plan Notes to Financial Statements December 31, 2005 1. DESCRIPTION OF THE PLAN The following description of the Belden CDT Inc. Retirement Savings Plan (Plan) provides only general information. Participants should refer to the Plan's Summary Plan Description for a more complete description of the Plan's provisions. GENERAL The Plan is a defined contribution plan with a 401(k) feature sponsored by Belden CDT Inc. (Company). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Effective July 15, 2004, Belden Inc. merged with Cable Design Technologies Corporation to form Belden CDT Inc. As a result of the merger, the Plan received one share of Belden CDT Inc. common stock for each share of Belden Inc. common stock. ELIGIBILITY FOR PARTICIPATION An eligible employee as defined by the Plan document becomes a participant of the Plan on the date of employment. CONTRIBUTIONS Participant contributions are remitted each pay period to the Plan by the employer from employee payroll deductions. Company 401(k) matching contributions are made to the Plan each pay period based on Plan provisions. The Plan also accepts qualified employee rollover contributions. Under the 401(k) feature, participants may contribute from 1% to 50% of their eligible compensation on a pretax basis. The Company matches 100% of the first 3% contributed and 50% of the second 3% contributed. The Company's matching contributions are used to purchase Belden CDT Inc. common stock. All contributions are subject to applicable limitations. Participant contributions and Company matching contributions are fully vested when they are made. Beginning January 1, 2006, the Company's matching contributions are made in cash and invested in the same manner as the participant's contributions. -7- Belden CDT Inc. Retirement Savings Plan Notes to Financial Statements (continued) A separate account is maintained for each participant, and participants may invest their savings in any combination of the available fund options in whole percent increments. Subject to the constraint described in the following sentence, participants can transfer their fund balance to another fund on a daily basis. Effective January 1, 2004, participants may transfer funds into or out of the Belden CDT Inc. common stock fund only to the extent such funds are attributable to the Company's previous matching contributions. Prior to January 1, 2004, participants could only transfer funds out of the Belden CDT Inc. common stock fund. Effective January 1, 2006, participants may only transfer funds out of the Belden CDT Inc. common stock fund. TRANSFERS Effective January 1, 2005, the CDT Retirement Savings Plan merged into the Belden CDT Inc. Retirement Savings Plan. The financial statements for 2005 reflect $29,825,151 in assets transferred into the Plan due to this merger. Investments, at fair value $28,247,448 Participant loans receivable 1,577,703 ---------------------- Total assets transferred $29,825,151 ====================== INVESTMENTS The Trustee holds all of the Plan assets and is responsible for benefit payments from the trust fund according to information submitted by the plan sponsor and participants. RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits. PARTICIPANT ACCOUNTS The Company has established and maintains accounts for each participant. These accounts are credited with investment income based upon the participants' account balances in relation to the total fund balances to which they have elected to contribute. -8- Belden CDT Inc. Retirement Savings Plan Notes to Financial Statements (continued) Prior to 1999, certain employees participated in an Individual Account Retirement (IAR) benefit feature. Under this feature, the Company made contributions and maintained separate accounts for each participant. When the IAR feature was discontinued, certain participants transferred their account balances out of the Plan. The fund balances of those IAR participants that elected to leave their account balances in the Plan are invested in the guaranteed income fund and are also credited with investment income. BENEFITS The Summary Plan Description, which is provided to participants, contains a description of the Plan and how participants may receive benefit payments. The Plan provides for the payment of benefits to participants upon retirement in a lump-sum payment, depending on the participant's election. A participant may elect to transfer his account to the Belden CDT Inc. Pension Plan for purposes of converting it to an annuity. WITHDRAWAL RIGHTS Participants may withdraw amounts from their accounts before retirement subject to Plan provisions and Internal Revenue Service (IRS) regulations. Participants are allowed to make hardship and age 59 1/2 withdrawals. PARTICIPANT LOANS Participants who are active employees of the Company are permitted to borrow from their accounts up to amounts specified in the Plan's provisions. Participants borrow at interest rates determined by the Plan and may not have more than one loan outstanding at any time. PLAN TERMINATION Although the Company has not expressed any intent to terminate the Plan, the Company has the right under the Plan to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants are fully vested in their accounts. -9- Belden CDT Inc. Retirement Savings Plan Notes to Financial Statements (continued) 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF ACCOUNTING The financial statements of the Plan have been prepared using the accrual basis of accounting. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. INVESTMENT VALUATION/INCOME RECOGNITION Investments in pooled separate accounts are stated at fair value as determined by Prudential Retirement Insurance Company (Prudential), the custodian, and are based on the net asset value of units held at year-end. The Plan's investment in the guaranteed income fund is valued at fair value as defined by Prudential. Prudential has the right to defer transfers or distributions under certain limited circumstances. Shares of Belden CDT Inc. common stock are valued at the closing bid price on the last business day of the year. Loans to participants are valued at cost, which approximates fair value. ADMINISTRATIVE EXPENSES In accordance with the provisions of the Plan, certain administrative expenses, such as trustee fees and investment management fees, were paid by the Plan and are included in the accompanying financial statements. Any administrative expenses not meeting the Plan provisions were paid by the Company and are not included in the accompanying financial statements. -10- Belden CDT Inc.

INCOME TAX STATUS The Plan has received a determination letter from the IRS dated July 22, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (Code) and that the related trust is exempt from taxation. Subsequent to the issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan's sponsor believes the Plan, as amended, is operated in conformity with the applicable requirements of the Code and therefore believes the Plan is qualified and the related trust is tax-exempt. -12- Belden CDT Inc.
