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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.

Participants should refer to the Plan document for more complete information. (a) General The Plan is a qualified deferred compensation plan, subject to the Employee Retirement Income Security Act of 1974 (ERISA). Any non-highly compensated salaried employee of Denny's Corporation (Denny's or the Company), who has attained age 21 and has completed 6 months of service with the Company is eligible to participate in the Plan. The Plan's committee and plan administrator control and manage the operation and administration of the Plan. Ameriprise Financial (formerly known as American Express Trust Company) serves as the Plan's trustee. On an annual basis, assets of employees who have changed status, as defined in the plan document, are transferred between the Denny's Salaried 401(k) Plan and the Denny's Hourly/HCE 401(k) Plan. During 2005 and 2004, transfers from (to) the Denny's Hourly/HCE 401(k) Plan due to change in status totaled $(3,790,741) and $580,333, respectively. (b) Interest in Master Trust The Plan's investments are held in the Denny's 401(k) Plans Master Trust (the Master Trust) which was established for the investment of assets of the Plan and the Denny's Hourly/HCE 401(k) Plan. (c) Contributions Each year, participants may make pre-tax contributions of up to 25% of eligible compensation. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. In 2005 and 2004, the Company matched 100% of employee pre-tax contributions, up to 3% of compensation for all participating employees of the Company. Contributions are subject to certain Internal Revenue Code (IRC) limitations. Excess contributions to be returned to participants are shown as a liability in the accompanying statements of net assets available for benefits. (d) Participant Accounts Individual accounts are maintained for each plan participant. Each participant's account is credited with the participant's contribution and allocations of the Company's contributions and earnings, and is charged with allocations of plan losses and administrative expenses and benefit payments, if applicable. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. (e) Vesting All participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's matching and discretionary contribution portion of their accounts plus actual earnings thereon is based on years of continuous service. For each employee whose initial date of employment is on or after January 1, 2002, the Company's contribution portion of his/her 5 account plus actual earnings thereon will be 100% vested after three years of continuous service unless the following terms provide for more accelerated vesting. For certain employees who were initially employed by the Company or its predecessor companies before January 1, 1999, participants are immediately vested in their contributions and employer contributions plus actual earnings thereon. (f) Investment Options Participants direct both participant and employer contributions in 1% increments in a combination of any of 12 investment options currently offered by the Plan. Participants may change their investment options at any time via telephone. (g) Participant Loans Participants may borrow from their fund accounts up to the lesser of 50% of the vested portion of their account balance, or the amount of $50,000 less the highest outstanding loan balance during the prior 12-month period. The minimum loan amount is $1,000, and each participant may have only one loan outstanding at any time. The plan document indicates that a reasonable borrowing rate will be assessed, typically evidenced by the prime rate charged by the Plan's trustee. The loans are secured by the balance in the participant's account. The participant also bears any loan administration costs incurred. Loans are repaid through payroll deductions in equal installments with the loan terms ranging from 6 to 54 months. Loan repayments cannot exceed 30% of the participant's salary. If an employee who has a loan outstanding terminates employment, no benefit will be paid from the Plan to the participant until the outstanding loan balance and accrued interest is paid in full. Loans outstanding at December 31, 2005 have a range of interest rates from 4.00% to 7.00%. (h) Payment of Benefits On termination of service due to death, disability, or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account, or annual installments over a 10-year period. For termination of service due to other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. (i) Administrative Expenses Administrative expenses of the Plan are paid by the Plan. (j) Withdrawals Withdrawals during employment are permitted only under hardship circumstances that are determined by the Internal Revenue Service "Safe Harbor" rules. Participants who are age 59-1/2 or older may withdraw from their account at any time, for any reason allowed by law. (k) Forfeited Accounts Forfeitures are used to reduce future employer contributions to the Plan. In 2005 and 2004, forfeitures of $44,502 and $10,156, respectively, were forfeited and will be used to reduce employer contributions. (2) Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying financial statements have been prepared on the accrual basis of accounting and in accordance with accounting principles generally accepted in the United States of America. 6 (b) 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 and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates. (c) Investment Valuation and Income Recognition The Plan's interest in Denny's 401(k) Plans Master Trust is presented at fair value, which has been determined based on the fair value of the underlying investments of the Master Trust. The fair value of mutual funds and Denny's Corporation common stock is determined by quoted market prices. The collective trust funds do not have quoted market prices. The fair value of the collective trust funds is determined based on the net asset value of the respective funds, which are based on the estimated fair value of the underlying investments in each fund. Such underlying investments are generally valued based on quoted market prices. Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. (d) Payment of Benefits Benefit payments to participants are recorded upon distribution. (e) Investment Risk The Trust provides for investments that are exposed to risk, such as interest rate, credit, and market volatility risk. Due to the level of risk associated with certain investment securities, it is possible that changes in the value of investment securities may occur in the near future and that changes could materially affect the amounts reported in the statement of net assets available for benefits. (3) Master Trust All of the Plan's investment assets are held in a trust account at Ameriprise Financial and consist of an undivided interest in an investment account of the Denny's 401(k) Plans Master Trust, a master trust established by the Company and administered by Ameriprise Financial, the Plan's trustee. Use of the Master Trust permits the commingling of trust assets with the assets of the Denny's Hourly/HCE 401(k) plan for investment and administrative purposes. Although assets of both plans are commingled in the Master Trust, the trustee maintains supporting records for the purpose of allocating the net gain or loss of the investment account to the participating plans. The net investment income or loss of the investment assets is allocated by the trustee to each participating plan based on the relationship of the interest of each plan to the total of the interest of the participating plans. 7 Investments of the Master Trust at December 31, 2005 and 2004 are summarized as follows: 2005 2004 ------------ ----------- Collective trust funds, at estimated fair value: RiverSource Emerging Growth Fund II $ 6,071,327 5,999,754 RiverSource Equity Index Fund II 9,901,657 9,883,738 RiverSource Income Fund II 46,217,907 46,985,680 RiverSource International Equity Index Fund II 573,466 367,445 RiverSource Money Market Fund I 51,614 84,676 RiverSource Small Cap Equity Index Fund II 798,922 721,580 ------------ ----------- Total 63,614,893 64,042,873 ------------ ----------- Mutual funds, at quoted market price: RiverSource New Dimensions Fund Y 1,429,753 1,407,951 Allianz NFJ Small Capital Value Fund 6,318,756 6,253,842 Spartan Total Money Market Index Fund --- 378,049 Templeton Foreign Fund 6,711,541 6,393,383 Vanguard Total Stock Market Index Fund I 763,104 107,745 Washington Mutual Investors Fund 1,427,704 1,407,526 ------------ ----------- Total 16,650,858 15,948,496 ------------ ----------- Denny's Corporation common stock at quoted market price 1,716,055 2,111,180 Loans to participants, at estimated fair value 1,037,611 893,047 Uninvested cash --- 190,371 ------------ ----------- Total investments $ 83,019,417 83,185,967 ============ =========== Plan's investment in the Master Trust $ 41,201,349 44,562,233 ============ =========== Plan's investment in the Master Trust as a percentage of total 49.63% 53.57% ============ =========== The net investment gain for the Master Trust for the years ended December 31, 2005 and 2004 is summarized below: 2005 2004 ------------ ----------- Net appreciation (depreciation) in fair value of investments: Collective trust funds $ 2,460,850 3,158,333 Mutual funds 1,407,996 2,491,802 Common Stock (159,888) 1,792,563 ------------ ----------- 3,708,958 7,442,698 Interest and dividend income 44,950 32,232 ------------ ----------- Total investment gain $ 3,753,908 7,474,930 ============ =========== Effective August 1, 2005, American Express Retirement Services changed its name to Ameriprise Financial. As a result, the American Express Trust collective fund families were renamed RiverSource. Effective April 1, 2005 PIMCO Advisors changed its name to Allianz Global Investors. As a result, the name of the PIMCO NFJ Small Capital Value Fund was changed to Allianz NFJ Small Capital Value Fund. The Plan's share of the Master Trust investment gain for the years ended December 31, 2005 and 2004 was 49.7% and 57.6%, respectively. 8 (4) Party-in-Interest Transactions The RiverSource collective trust funds and RiverSource New Dimensions Fund Y mutual fund are managed by Ameriprise Financial. Ameriprise Financial serves as trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan to Ameriprise Financial for the years ended December 31, 2005 and 2004 amounted to approximately $47,000 and $56,000, respectively. The Master Trust also invests in common stock of the Plan's sponsor. These transactions also qualify as party-in-interest transactions. (5) Plan Termination Although it has not expressed any intention to do so, the Company has the right under the Plan to terminate the Plan subject to the provisions set forth in ERISA. In the event that the Plan is terminated participants would become 100% vested in their accounts. (6) Tax Status The Internal Revenue Service has issued a favorable determination letter dated January 17, 2003, indicating that the Plan qualifies under the applicable section of the IRC and is, therefore, not subject to tax under present income tax laws. A Plan is required to operate in conformity with the IRC in order to maintain its qualification. The Plan's management is not aware of any course of action or series of events that have occurred that might adversely affect the Plan's qualified status. (7) Subsequent Event On February 1, 2006, the Company transitioned its 401(k) record keeping and trustee duties from Ameriprise Financial to Wells Fargo. Also on this date the Plan was merged with the Denny's Hourly/HCE 401(k) Plan to form the Denny's 401(k) Plan. In conjunction with this, Denny's Corporation common stock was removed as an investment option. This transaction was overseen and approved by the Plan's committee. 9 DENNY'S HOURLY/HCE 401(k) PLAN Financial Statements December 31, 2005 and 2004 (With Report of Independent Registered Public Accounting Firm Thereon) 10 DENNY'S HOURLY/HCE 401(k) PLAN Financial Statements December 31, 2005 and 2004 Index Page Report of Independent Registered Public Accounting Firm 12 Statements of Net Assets Available for Benefits - December 31, 2005 and 2004 13 Statements of Changes in Net Assets Available for Benefits - Years ended December 31, 2005 and 2004 14 Notes to Financial Statements 15-19 Note: The accompanying financial statements have been prepared for the purpose of filing with Department of Labor's Form 5500.

The net investment income or loss of the investment assets is allocated by the trustee to each participating plan based on the relationship of the interest of each plan to the total of the interests of the participating plans. 17 The investments of the Master Trust at December 31, 2005 and 2004, are summarized as follows: 2005 2004 ------------ ----------- Collective trust funds, at estimated fair value: RiverSource Emerging Growth Fund II $ 6,071,327 5,999,754 RiverSource Equity Index Fund II 9,901,657 9,883,738 RiverSource Income Fund II 46,217,907 46,985,680 RiverSource International Equity Index Fund II 573,466 367,445 RiverSource Money Market Fund I 51,614 84,676 RiverSource Small Cap Equity Index Fund II 798,922 721,580 ------------ ----------- Total 63,614,893 64,042,873 ------------ ----------- Mutual funds, at quoted market price: RiverSource New Dimensions Fund Y 1,429,753 1,407,951 Allianz NFJ Small Capital Value Fund 6,318,756 6,253,842 Spartan Total Money Market Index Fund --- 378,049 Templeton Foreign Fund 6,711,541 6,393,383 Vanguard Total Stock Market Index Fund I 763,104 107,745 Washington Mutual Investors Fund 1,427,704 1,407,526 ------------ ----------- Total 16,650,858 15,948,496 ------------ ----------- Denny's Corporation common stock at quoted market price 1,716,055 2,111,180 Loans to participants, at estimated fair value 1,037,611 893,047 Uninvested cash --- 190,371 ------------ ----------- Total investments $ 83,019,417 83,185,967 ============ =========== Plan's investment in the Master Trust $ 41,818,067 38,623,734 ============ =========== Plan's investment in the Master Trust as a percentage of total 50.37% 46.43% ============ =========== The net investment gain for the Master Trust for the years ended December 31, 2005 and 2004 is summarized below: 2005 2004 ------------ ----------- Net appreciation (depreciation) in fair value of investments: Collective trust funds $ 2,460,850 3,158,333 Mutual funds 1,407,996 2,491,802 Common Stock (159,888) 1,792,563 ------------ ----------- 3,708,958 7,442,698 Interest and dividend income 44,950 32,232 ------------ ----------- Total investment gain $ 3,753,908 7,474,930 ============ =========== Effective August 1, 2005, American Express Retirement Services changed its name to Ameriprise Financial. As a result, the American Express Trust collective fund families were renamed RiverSource. Effective April 1, 2005 PIMCO Advisors changed its name to Allianz Global Investors. As a result, the name of the PIMCO NFJ Small Capital Value Fund was changed to Allianz NFJ Small Capital Value Fund. The Plan's share of the Master Trust investment gain for the years ended December 31, 2005 and 2004 was 50.3% and 42.4%, respectively. 18 (4) Party-In-Interest Transactions The RiverSource collective trust funds and RiverSource New Dimensions Y mutual fund are managed by Ameriprise Financial. Ameriprise Financial serves as trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan to Ameriprise Financial for the years ended December 31, 2005 and 2004 amounted to approximately $47,000 and $56,000, respectively. The Master Trust also invests in the common stock of the Plan's sponsor. These transactions also qualify as party-in-interest transactions. (5) Plan Termination Although it has not expressed any intention to do so, the Company has the right under the Plan to terminate the Plan subject to the provisions set forth in ERISA. In the event that the Plan is terminated, participants would become 100% vested in their accounts. (6) Tax Status The Internal Revenue Service has issued a favorable determination letter dated January 17, 2003, indicating that the Plan qualifies under the applicable sections of the IRC and is, therefore, not subject to tax under present income tax laws. A Plan is required to operate in conformity with the IRC in order to maintain its qualification. The Plan's management is not aware of any course of action or series of events that have occurred that might adversely affect the Plan's qualified status. (7) Subsequent Event On February 1, 2006, the Company transitioned its 401(k) record keeping and trustee duties from Ameriprise Financial to Wells Fargo. Also on this date the Plan was merged with the Denny's Salaried 401(k) Plan to form the Denny's 401(k) Plan. In conjunction with this, Denny's Corporation common stock was removed as an investment option. This transaction was overseen and approved by the Plan's committee. 19 SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the trustees (or other persons who administer the employee benefit plans) have duly caused this annual report to be signed on its behalf by the undersigned, hereunto duly authorized.
