Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2014
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates. In preparing our Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles, management is required to make certain assumptions and estimates that affect reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingencies. In making these assumptions and estimates, management may from time to time seek advice and consider information provided by actuaries and other experts in a particular area. Actual amounts could differ materially from these estimates.
Consolidation Policy	Consolidation Policy. Our Consolidated Financial Statements include the financial statements of Denny’s Corporation and its wholly-owned subsidiaries: Denny’s, Inc., DFO, LLC and Denny's Realty, LLC. All significant intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year. Our fiscal year ends on the last Wednesday in December. As a result, a fifty-third week is added to a fiscal year every five or six years. Fiscal 2014 included 53 weeks of operations, whereas 2013 and 2012 each included 52 weeks of operations.
Reclassifications	Reclassifications. The prior year proceeds and repayments of the revolving credit facility have been reclassified in the Consolidated Statement of Cash Flows to conform to the current gross basis presentation.
Cash Equivalents and Short-term Investments and Cash Overdrafts	Cash Overdrafts. There were no cash overdrafts at December 31, 2014. Accounts payable in our Consolidated Balance Sheets include cash overdrafts of $1.6 million at December 25, 2013. Changes in such amounts are reflected in cash flows from financing activities in the Consolidated Statements of Cash Flows. Cash Equivalents and Short-term Investments. Our policy is to invest cash in excess of operating requirements in short-term highly liquid investments with an original maturity of three months or less, which we consider to be cash equivalents. Cash and cash equivalents include short-term investments of $5.0 million and $5.3 million at December 31, 2014 and December 25, 2013, respectively.
Receivables	Receivables. Receivables, which are recorded at net realizable value, primarily consist of trade accounts receivables and financing receivables from franchisees (together “franchisee receivables”), vendor receivables and credit card receivables. Trade accounts receivables from franchisees consist of royalties, advertising and rent. Financing receivables from franchisees primarily consist of notes from franchisees related to the roll-out of new POS equipment. We accrue interest on notes receivable based on the contractual terms. The allowance for doubtful accounts is based on pre-defined criteria and management’s judgment of existing receivables. Receivables that are ultimately deemed to be uncollectible, and for which collection efforts have been exhausted, are written off against the allowance for doubtful accounts.
Inventories	Inventories. Inventories consist of food and beverages and are valued primarily at the lower of average cost (first-in, first-out) or market.
Property and Depreciation	Property and Depreciation. Owned property is stated at cost. Property under capital leases is stated at the lesser of its fair value or the net present value of the related minimum lease payments at the lease inception. Maintenance and repairs are expensed as incurred. We depreciate owned property over its estimated useful life using the straight-line method. We amortize property held under capital leases (at capitalized value) over the lesser of its estimated useful life or the initial lease term. In certain situations, one or more option periods may be used in determining the depreciable life of certain leasehold improvements under operating lease agreements, if we deem that an economic penalty will be incurred and exercise of such option periods is reasonably assured. In either circumstance, our policy requires lease term consistency when calculating the depreciation period, in classifying the lease and in computing rent expense. Building assets are assigned estimated useful lives that range from five to 30 years. Equipment assets are assigned lives that range from two to ten years. Leasehold improvements are generally assigned lives between five and 15 years limited by the expected lease term.
Goodwill	Goodwill. Amounts recorded as goodwill primarily represent excess reorganization value recognized as a result of our 1998 bankruptcy. We record goodwill in connection with the acquisition of restaurants from franchisees. Likewise, upon the sale of restaurant operations to franchisees, goodwill is decremented. We test goodwill for impairment at each fiscal year end, and more frequently if circumstances indicate impairment may exist. Such indicators include, but are not limited to, a significant decline in our expected future cash flows; a significant adverse decline in our stock price; significantly adverse legal developments; and a significant change in the business climate.
Other Intangible Assets	Other Intangible Assets. Other intangible assets consist primarily of trade names, franchise and license agreements, and reacquired franchise rights. Trade names are considered indefinite-lived intangible assets and are not amortized. Franchise and license agreements and reacquired franchise rights are amortized using the straight-line basis over the term of the related agreement. We test trade name assets for impairment at each fiscal year end, and more frequently if circumstances indicate impairment may exist. We assess impairment of franchise and license agreements and reacquired franchise rights whenever changes or events indicate that the carrying value may not be recoverable. Costs incurred to renew or extend the term of recognized intangible assets are recorded in general and administrative expenses in our Consolidated Statements of Income.
Long-term Investments	Long-term Investments. Long-term investments include nonqualified deferred compensation plan assets held in a rabbi trust. Each plan participant's account is comprised of their contribution, our matching contribution and each participant's share of earnings or losses in the plan. The investments of the rabbi trust include debt and equity mutual funds. They are considered trading securities and are reported at fair value in other noncurrent assets with an offsetting liability included in other noncurrent liabilities and deferred credits in our Consolidated Balance Sheets. The realized and unrealized holding gains and losses related to the investments are recorded in other income (expense) with an offsetting amount recorded in general and administrative expenses related to the liability in our Consolidated Statements of Income.
Deferred Financing Costs	Deferred Financing Costs. Costs related to the issuance of debt are deferred and amortized as a component of interest expense using the effective interest method over the terms of the respective debt issuances.
Self-Insurance Liabilities	Self-insurance liabilities. We record liabilities for insurance claims during periods in which we have been insured under large deductible programs or have been self-insured for our medical claims and workers’ compensation, general/product and automobile insurance liabilities. The liabilities for prior and current estimated incurred losses are discounted to their present value based on expected loss payment patterns determined by independent actuaries using our actual historical payments. These estimates include assumptions regarding claims frequency and severity as well as changes in our business environment, medical costs and the regulatory environment that could impact our overall self-insurance costs.
Income Taxes	Income Taxes. We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance reduces our net deferred tax assets to the amount that is more likely than not to be realized. We make certain estimates and judgments in the calculation of our provision for incomes taxes, in the resulting tax liabilities, and in the recoverability of deferred tax assets.
Leases and Subleases	Leases and Subleases. Our policy requires the use of a consistent lease term for (i) calculating the maximum depreciation period for related buildings and leasehold improvements; (ii) classifying the lease; and (iii) computing periodic rent expense increases where the lease terms include escalations in rent over the lease term. The lease term commences on the date we gain access to and control over the leased property. We account for rent escalations in leases on a straight-line basis over the expected lease term. Any rent holidays after lease commencement are recognized on a straight-line basis over the expected lease term, which includes the rent holiday period. Leasehold improvements that have been funded by lessors have historically been insignificant. Any leasehold improvements we make that are funded by lessor incentives or allowances under operating leases are recorded as leasehold improvement assets and amortized over the expected lease term. Such incentives are also recorded as deferred rent and amortized as reductions to lease expense over the expected lease term. We record contingent rent expense based on estimated sales for respective restaurants over the contingency period. Contingent rental income is recognized when earned.
Fair Value Measurements	Fair Value Measurements. The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses are deemed to approximate fair value due to the immediate or short-term maturity of these instruments. The fair value of notes receivable approximates the carrying value after consideration of recorded allowances and related risk-based interest rates. The liabilities under our credit facility are carried at historical cost. The estimated fair value (Level 2) of our senior secured term loan approximates its carrying value. The fair value of our long-term debt is determined based on market prices or, if market prices are not available, the present value of the underlying cash flows discounted at market rates.
Derivative Instruments	Derivative Instruments. We use derivative financial instruments to manage our exposure to interest rate risk. We do not enter into derivative instruments for trading or speculative purposes. All derivatives are recognized on our Consolidated Balance Sheets at fair value based upon quoted market prices. Changes in the fair values of derivatives are recorded in earnings or other comprehensive income, based on whether the instrument is designated as a hedge transaction. Gains or losses on derivative instruments reported in other comprehensive income are classified to earnings in the period the hedged item affects earnings. If the underlying hedge transaction ceases to exist, any associated amounts reported in other comprehensive income are reclassified to earnings at that time. Any ineffectiveness is recognized in earnings in the current period. By entering into derivative instruments, we are exposed to counterparty credit risk. When the fair value of a derivative instrument is in an asset position, the counterparty has a liability to us, which creates credit risk for us. We manage our exposure to this risk by selecting counterparties with investment grade credit ratings and regularly monitoring our market position with each counterparty.
Contingencies and Litigation	Contingencies and Litigation. We are subject to legal proceedings involving ordinary and routine claims incidental to our business, as well as legal proceedings that are nonroutine and include compensatory or punitive damage claims. Our ultimate legal and financial liability with respect to such matters cannot be estimated with certainty and requires the use of estimates in recording liabilities for potential litigation settlements. When the reasonable estimate is a range, the recorded loss will be the best estimate within the range. We record legal settlement costs as other operating expenses in our Consolidated Statements of Income as those costs are incurred.
Comprehensive Income	Comprehensive Income. Comprehensive income includes net income and other comprehensive income items that are excluded from net income under U.S. generally accepted accounting principles. Other comprehensive income items include additional minimum pension liability adjustments and the effective unrealized portion of changes in the fair value of cash flow hedges.
Segment	Segment. Denny’s operates in only one segment. All significant revenues and pre-tax earnings relate to retail sales of food and beverages to the general public through either company or franchised restaurants.
Company Restaurant Sales	Company Restaurant Sales. Company restaurant sales are recognized when food and beverage products are sold at company restaurants. We present company restaurant sales net of sales taxes.
Gift Cards	Gift cards. We sell gift cards which have no stated expiration dates. We recognize revenue from gift cards when the gift card is redeemed by the customer or when we determine the likelihood of redemption is remote (gift card breakage). Breakage is based on our company-specific historical redemption patterns.
Franchise and License Fees	Franchise and License Fees. We recognize initial franchise and license fees when all of the material obligations have been performed and conditions have been satisfied, typically when operations of a new franchised restaurant have commenced. Continuing fees, such as royalties and rents, are recorded as income.
Advertising Costs	Advertising Costs. We expense production costs for radio and television advertising in the year in which the commercials are initially aired.
Restructuring and exit costs	Restructuring and exit costs. Restructuring and exit costs consist primarily of the costs of future obligations related to closed restaurants, severance and other restructuring charges for terminated employees, and are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income. Discounted liabilities for future lease costs and the fair value of related subleases of closed restaurants are recorded when the restaurants are closed. All other costs related to closed restaurants are expensed as incurred. In assessing the discounted liabilities for future costs of obligations related to closed restaurants, we make assumptions regarding amounts of future assumed subleases. If these assumptions or their related estimates change in the future, we may be required to record additional exit costs or reduce exit costs previously recorded. Exit costs recorded for each of the periods presented include the effect of such changes in estimates. We evaluate restaurant closures for potential disclosure as discontinued operations based on an assessment of several quantitative and qualitative factors, including the nature of the closure, revenue migration to other company and franchised restaurants and planned market development in the vicinity of the disposed restaurant.
Impairment of Long-lived Assets	Disposal or Impairment of Long-lived Assets. We evaluate our long-lived assets for impairment at the restaurant level on a quarterly basis, when assets are identified as held for sale or whenever changes or events indicate that the carrying value may not be recoverable. For assets identified as held for sale, we use the market approach and consider proceeds from similar asset sales. We assess impairment of restaurant-level assets based on the operating cash flows of the restaurant, expected proceeds from the sale of assets and our plans for restaurant closings. Generally, all restaurants with negative cash flows from operations for the most recent twelve months at each quarter end are included in our assessment. For underperforming assets, we use the income approach to determine both the recoverability and estimated fair value of the assets. To estimate future cash flows we make certain assumptions about expected future operating performance, such as revenue growth, operating margins, risk-adjusted discount rates, and future economic and market conditions. If the long-lived assets of a restaurant are not recoverable based upon estimated future, undiscounted cash flows, we write the assets down to their fair value. If these estimates or their related assumptions change in the future, we may be required to record additional impairment charges. These charges are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income. Assets held for sale consist of real estate properties and/or restaurant operations that we expect to sell within the next year. The assets are reported at the lower of carrying amount or fair value less costs to sell. We cease recording depreciation on assets that are classified as held for sale. If the determination is made that we no longer expect to sell an asset within the next year, the asset is reclassified out of held for sale.
Gains on Sales of Restaurants Operations to Franchisees, Real Estate and Other Assets	Gains on Sales of Restaurants Operations to Franchisees, Real Estate and Other Assets. Generally, gains on sales of restaurant operations to franchisees (which may include real estate), real estate properties and other assets are recognized when the sales are consummated and certain other gain recognition criteria are met. Total gains are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income.
Share-based Compensation	Share-Based Compensation. Share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the requisite service period. We estimate potential forfeitures of share-based awards and adjust the forfeiture rate over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Share-based compensation expense is included as a component of general and administrative expenses in our Consolidated Statements of Income. Any tax expense or benefit in excess of recognized compensation cost is reported as a financing activity on our Consolidated Statements of Cash Flows. Compensation expense for options is recognized on a straight-line basis over the requisite service period for the entire award. Generally, compensation expense related to restricted stock units, performance shares, performance units and board deferred stock units is based on the number of shares and units expected to vest, the period over which they are expected to vest and the fair market value of the common stock on the date of the grant. For restricted stock units and performance shares that contain a market condition, compensation expense is based on the Monte Carlo valuation method, which utilizes multiple input variables to determine the probability of the Company achieving the market condition and the fair value of the award. The amount of certain cash-settled awards is determined based on the date of payment. Therefore, compensation expense related to these cash-settled awards is adjusted to fair value at each balance sheet date. Subsequent to the vesting period, earned stock-settled restricted stock units and performance shares (both of which are equity classified) are paid to the holder in shares of common stock, and the cash-settled restricted stock units and performance units (both of which are liability classified) are paid to the holder in cash, provided the holder is then still employed with Denny’s or an affiliate.
Earnings Per Share	Earnings Per Share. Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period.
Accounting Standards to be Adopted	Accounting Standards to be Adopted. Discontinued Operations ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" In April 2014, the FASB issued ASU 2014-08, which raises the threshold for a disposal to qualify as a discontinued operation and modifies the related disclosure requirements. Under the new guidance, only disposals resulting in a strategic shift that will have a major effect on an entity's operations and financial results will be reported as discontinued operations. ASU 2014-08 also removes the requirement that an entity not have any significant continuing involvement in the operations of the component after disposal to qualify for reporting of the disposal as a discontinued operation. The guidance is effective for annual and interim periods beginning after December 15, 2014 (our fiscal 2015), with early adoption permitted for any disposal transaction not previously reported. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. Revenue Recognition ASU 2014-09, "Revenue from Contracts with Customers" In May 2014, the FASB issued ASU 2014-09, which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or service to a customer in an amount that reflects the consideration to which a company expects to be entitled. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016 (our fiscal 2017). The guidance allows for either a "full retrospective" adoption or a "modified retrospective" adoption, however early adoption is not permitted. We are currently evaluating the adoption methods and the impact the adoption of this guidance will have on our consolidated financial statements, however we do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. Share-Based Compensation ASU 2014-12, "Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force)" In June 2014, the FASB issued ASU No. 2014-12, which clarifies the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASI 2014-12 is effective for annual and interim periods beginning after December 15, 2015 (our fiscal 2016) with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements, Going Concern ASU 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern" In August 2014, the FASB issued ASU 2014-15, which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016 (our fiscal 2017) with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements. We reviewed all other newly issued accounting pronouncements and concluded that they are either not applicable to our business or are not expected to have a material effect on the financial statements as a result of future adoption.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Use of Estimates. In preparing our Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles, management is required to make certain assumptions and estimates that affect reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingencies. In making these assumptions and estimates, management may from time to time seek advice and consider information provided by actuaries and other experts in a particular area. Actual amounts could differ materially from these estimates.

Consolidation Policy

Consolidation Policy. Our Consolidated Financial Statements include the financial statements of Denny’s Corporation and its wholly-owned subsidiaries: Denny’s, Inc., DFO, LLC and Denny's Realty, LLC. All significant intercompany balances and transactions have been eliminated in consolidation.

Fiscal Year

Fiscal Year. Our fiscal year ends on the last Wednesday in December. As a result, a fifty-third week is added to a fiscal year every five or six years. Fiscal 2014 included 53 weeks of operations, whereas 2013 and 2012 each included 52 weeks of operations.

Reclassifications

Reclassifications. The prior year proceeds and repayments of the revolving credit facility have been reclassified in the Consolidated Statement of Cash Flows to conform to the current gross basis presentation.

Cash Equivalents and Short-term Investments and Cash Overdrafts

Cash Overdrafts. There were no cash overdrafts at December 31, 2014. Accounts payable in our Consolidated Balance Sheets include cash overdrafts of $1.6 million at December 25, 2013. Changes in such amounts are reflected in cash flows from financing activities in the Consolidated Statements of Cash Flows.

Cash Equivalents and Short-term Investments. Our policy is to invest cash in excess of operating requirements in short-term highly liquid investments with an original maturity of three months or less, which we consider to be cash equivalents. Cash and cash equivalents include short-term investments of $5.0 million and $5.3 million at December 31, 2014 and December 25, 2013, respectively.

Receivables

Receivables. Receivables, which are recorded at net realizable value, primarily consist of trade accounts receivables and financing receivables from franchisees (together “franchisee receivables”), vendor receivables and credit card receivables. Trade accounts receivables from franchisees consist of royalties, advertising and rent. Financing receivables from franchisees primarily consist of notes from franchisees related to the roll-out of new POS equipment. We accrue interest on notes receivable based on the contractual terms. The allowance for doubtful accounts is based on pre-defined criteria and management’s judgment of existing receivables. Receivables that are ultimately deemed to be uncollectible, and for which collection efforts have been exhausted, are written off against the allowance for doubtful accounts.

Inventories

Inventories. Inventories consist of food and beverages and are valued primarily at the lower of average cost (first-in, first-out) or market.

Property and Depreciation

Property and Depreciation. Owned property is stated at cost. Property under capital leases is stated at the lesser of its fair value or the net present value of the related minimum lease payments at the lease inception. Maintenance and repairs are expensed as incurred. We depreciate owned property over its estimated useful life using the straight-line method. We amortize property held under capital leases (at capitalized value) over the lesser of its estimated useful life or the initial lease term. In certain situations, one or more option periods may be used in determining the depreciable life of certain leasehold improvements under operating lease agreements, if we deem that an economic penalty will be incurred and exercise of such option periods is reasonably assured. In either circumstance, our policy requires lease term consistency when calculating the depreciation period, in classifying the lease and in computing rent expense. Building assets are assigned estimated useful lives that range from five to 30 years. Equipment assets are assigned lives that range from two to ten years. Leasehold improvements are generally assigned lives between five and 15 years limited by the expected lease term.

Goodwill

Goodwill. Amounts recorded as goodwill primarily represent excess reorganization value recognized as a result of our 1998 bankruptcy. We record goodwill in connection with the acquisition of restaurants from franchisees. Likewise, upon the sale of restaurant operations to franchisees, goodwill is decremented. We test goodwill for impairment at each fiscal year end, and more frequently if circumstances indicate impairment may exist. Such indicators include, but are not limited to, a significant decline in our expected future cash flows; a significant adverse decline in our stock price; significantly adverse legal developments; and a significant change in the business climate.

Other Intangible Assets

Other Intangible Assets. Other intangible assets consist primarily of trade names, franchise and license agreements, and reacquired franchise rights. Trade names are considered indefinite-lived intangible assets and are not amortized. Franchise and license agreements and reacquired franchise rights are amortized using the straight-line basis over the term of the related agreement. We test trade name assets for impairment at each fiscal year end, and more frequently if circumstances indicate impairment may exist. We assess impairment of franchise and license agreements and reacquired franchise rights whenever changes or events indicate that the carrying value may not be recoverable. Costs incurred to renew or extend the term of recognized intangible assets are recorded in general and administrative expenses in our Consolidated Statements of Income.

Long-term Investments

Long-term Investments. Long-term investments include nonqualified deferred compensation plan assets held in a rabbi trust. Each plan participant's account is comprised of their contribution, our matching contribution and each participant's share of earnings or losses in the plan. The investments of the rabbi trust include debt and equity mutual funds. They are considered trading securities and are reported at fair value in other noncurrent assets with an offsetting liability included in other noncurrent liabilities and deferred credits in our Consolidated Balance Sheets. The realized and unrealized holding gains and losses related to the investments are recorded in other income (expense) with an offsetting amount recorded in general and administrative expenses related to the liability in our Consolidated Statements of Income.

Deferred Financing Costs

Deferred Financing Costs. Costs related to the issuance of debt are deferred and amortized as a component of interest expense using the effective interest method over the terms of the respective debt issuances.

Self-Insurance Liabilities

Self-insurance liabilities. We record liabilities for insurance claims during periods in which we have been insured under large deductible programs or have been self-insured for our medical claims and workers’ compensation, general/product and automobile insurance liabilities. The liabilities for prior and current estimated incurred losses are discounted to their present value based on expected loss payment patterns determined by independent actuaries using our actual historical payments. These estimates include assumptions regarding claims frequency and severity as well as changes in our business environment, medical costs and the regulatory environment that could impact our overall self-insurance costs.

Income Taxes

Income Taxes. We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. A valuation allowance reduces our net deferred tax assets to the amount that is more likely than not to be realized. We make certain estimates and judgments in the calculation of our provision for incomes taxes, in the resulting tax liabilities, and in the recoverability of deferred tax assets.

Leases and Subleases

Leases and Subleases. Our policy requires the use of a consistent lease term for (i) calculating the maximum depreciation period for related buildings and leasehold improvements; (ii) classifying the lease; and (iii) computing periodic rent expense increases where the lease terms include escalations in rent over the lease term. The lease term commences on the date we gain access to and control over the leased property. We account for rent escalations in leases on a straight-line basis over the expected lease term. Any rent holidays after lease commencement are recognized on a straight-line basis over the expected lease term, which includes the rent holiday period. Leasehold improvements that have been funded by lessors have historically been insignificant. Any leasehold improvements we make that are funded by lessor incentives or allowances under operating leases are recorded as leasehold improvement assets and amortized over the expected lease term. Such incentives are also recorded as deferred rent and amortized as reductions to lease expense over the expected lease term. We record contingent rent expense based on estimated sales for respective restaurants over the contingency period. Contingent rental income is recognized when earned.

Fair Value Measurements

Fair Value Measurements. The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses are deemed to approximate fair value due to the immediate or short-term maturity of these instruments. The fair value of notes receivable approximates the carrying value after consideration of recorded allowances and related risk-based interest rates. The liabilities under our credit facility are carried at historical cost. The estimated fair value (Level 2) of our senior secured term loan approximates its carrying value. The fair value of our long-term debt is determined based on market prices or, if market prices are not available, the present value of the underlying cash flows discounted at market rates.

Derivative Instruments

Derivative Instruments. We use derivative financial instruments to manage our exposure to interest rate risk. We do not enter into derivative instruments for trading or speculative purposes. All derivatives are recognized on our Consolidated Balance Sheets at fair value based upon quoted market prices. Changes in the fair values of derivatives are recorded in earnings or other comprehensive income, based on whether the instrument is designated as a hedge transaction. Gains or losses on derivative instruments reported in other comprehensive income are classified to earnings in the period the hedged item affects earnings. If the underlying hedge transaction ceases to exist, any associated amounts reported in other comprehensive income are reclassified to earnings at that time. Any ineffectiveness is recognized in earnings in the current period. By entering into derivative instruments, we are exposed to counterparty credit risk. When the fair value of a derivative instrument is in an asset position, the counterparty has a liability to us, which creates credit risk for us. We manage our exposure to this risk by selecting counterparties with investment grade credit ratings and regularly monitoring our market position with each counterparty.

Contingencies and Litigation

Contingencies and Litigation. We are subject to legal proceedings involving ordinary and routine claims incidental to our business, as well as legal proceedings that are nonroutine and include compensatory or punitive damage claims. Our ultimate legal and financial liability with respect to such matters cannot be estimated with certainty and requires the use of estimates in recording liabilities for potential litigation settlements. When the reasonable estimate is a range, the recorded loss will be the best estimate within the range. We record legal settlement costs as other operating expenses in our Consolidated Statements of Income as those costs are incurred.

Comprehensive Income

Comprehensive Income. Comprehensive income includes net income and other comprehensive income items that are excluded from net income under U.S. generally accepted accounting principles. Other comprehensive income items include additional minimum pension liability adjustments and the effective unrealized portion of changes in the fair value of cash flow hedges.

Segment

Segment. Denny’s operates in only one segment. All significant revenues and pre-tax earnings relate to retail sales of food and beverages to the general public through either company or franchised restaurants.

Company Restaurant Sales

Company Restaurant Sales. Company restaurant sales are recognized when food and beverage products are sold at company restaurants. We present company restaurant sales net of sales taxes.

Gift Cards

Gift cards. We sell gift cards which have no stated expiration dates. We recognize revenue from gift cards when the gift card is redeemed by the customer or when we determine the likelihood of redemption is remote (gift card breakage). Breakage is based on our company-specific historical redemption patterns.

Franchise and License Fees

Franchise and License Fees. We recognize initial franchise and license fees when all of the material obligations have been performed and conditions have been satisfied, typically when operations of a new franchised restaurant have commenced. Continuing fees, such as royalties and rents, are recorded as income.

Advertising Costs

Advertising Costs. We expense production costs for radio and television advertising in the year in which the commercials are initially aired.

Restructuring and exit costs

Restructuring and exit costs. Restructuring and exit costs consist primarily of the costs of future obligations related to closed restaurants, severance and other restructuring charges for terminated employees, and are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income.

Discounted liabilities for future lease costs and the fair value of related subleases of closed restaurants are recorded when the restaurants are closed. All other costs related to closed restaurants are expensed as incurred. In assessing the discounted liabilities for future costs of obligations related to closed restaurants, we make assumptions regarding amounts of future assumed subleases. If these assumptions or their related estimates change in the future, we may be required to record additional exit costs or reduce exit costs previously recorded. Exit costs recorded for each of the periods presented include the effect of such changes in estimates.

We evaluate restaurant closures for potential disclosure as discontinued operations based on an assessment of several quantitative and qualitative factors, including the nature of the closure, revenue migration to other company and franchised restaurants and planned market development in the vicinity of the disposed restaurant.

Impairment of Long-lived Assets

Disposal or Impairment of Long-lived Assets. We evaluate our long-lived assets for impairment at the restaurant level on a quarterly basis, when assets are identified as held for sale or whenever changes or events indicate that the carrying value may not be recoverable. For assets identified as held for sale, we use the market approach and consider proceeds from similar asset sales. We assess impairment of restaurant-level assets based on the operating cash flows of the restaurant, expected proceeds from the sale of assets and our plans for restaurant closings. Generally, all restaurants with negative cash flows from operations for the most recent twelve months at each quarter end are included in our assessment. For underperforming assets, we use the income approach to determine both the recoverability and estimated fair value of the assets. To estimate future cash flows we make certain assumptions about expected future operating performance, such as revenue growth, operating margins, risk-adjusted discount rates, and future economic and market conditions. If the long-lived assets of a restaurant are not recoverable based upon estimated future, undiscounted cash flows, we write the assets down to their fair value. If these estimates or their related assumptions change in the future, we may be required to record additional impairment charges. These charges are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income.

Assets held for sale consist of real estate properties and/or restaurant operations that we expect to sell within the next year. The assets are reported at the lower of carrying amount or fair value less costs to sell. We cease recording depreciation on assets that are classified as held for sale. If the determination is made that we no longer expect to sell an asset within the next year, the asset is reclassified out of held for sale.

Gains on Sales of Restaurants Operations to Franchisees, Real Estate and Other Assets

Gains on Sales of Restaurants Operations to Franchisees, Real Estate and Other Assets. Generally, gains on sales of restaurant operations to franchisees (which may include real estate), real estate properties and other assets are recognized when the sales are consummated and certain other gain recognition criteria are met. Total gains are included as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income.

Share-based Compensation

Share-Based Compensation. Share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the requisite service period. We estimate potential forfeitures of share-based awards and adjust the forfeiture rate over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Share-based compensation expense is included as a component of general and administrative expenses in our Consolidated Statements of Income. Any tax expense or benefit in excess of recognized compensation cost is reported as a financing activity on our Consolidated Statements of Cash Flows.

Compensation expense for options is recognized on a straight-line basis over the requisite service period for the entire award. Generally, compensation expense related to restricted stock units, performance shares, performance units and board deferred stock units is based on the number of shares and units expected to vest, the period over which they are expected to vest and the fair market value of the common stock on the date of the grant. For restricted stock units and performance shares that contain a market condition, compensation expense is based on the Monte Carlo valuation method, which utilizes multiple input variables to determine the probability of the Company achieving the market condition and the fair value of the award. The amount of certain cash-settled awards is determined based on the date of payment. Therefore, compensation expense related to these cash-settled awards is adjusted to fair value at each balance sheet date.

Subsequent to the vesting period, earned stock-settled restricted stock units and performance shares (both of which are equity classified) are paid to the holder in shares of common stock, and the cash-settled restricted stock units and performance units (both of which are liability classified) are paid to the holder in cash, provided the holder is then still employed with Denny’s or an affiliate.

Earnings Per Share

Earnings Per Share. Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period.

Accounting Standards to be Adopted

Accounting Standards to be Adopted.

Discontinued Operations

ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity"

In April 2014, the FASB issued ASU 2014-08, which raises the threshold for a disposal to qualify as a discontinued operation and modifies the related disclosure requirements. Under the new guidance, only disposals resulting in a strategic shift that will have a major effect on an entity's operations and financial results will be reported as discontinued operations. ASU 2014-08 also removes the requirement that an entity not have any significant continuing involvement in the operations of the component after disposal to qualify for reporting of the disposal as a discontinued operation. The guidance is effective for annual and interim periods beginning after December 15, 2014 (our fiscal 2015), with early adoption permitted for any disposal transaction not previously reported. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

Revenue Recognition

ASU 2014-09, "Revenue from Contracts with Customers"

In May 2014, the FASB issued ASU 2014-09, which clarifies the principles used to recognize revenue for all entities. The new guidance requires companies to recognize revenue when it transfers goods or service to a customer in an amount that reflects the consideration to which a company expects to be entitled. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016 (our fiscal 2017). The guidance allows for either a "full retrospective" adoption or a "modified retrospective" adoption, however early adoption is not permitted. We are currently evaluating the adoption methods and the impact the adoption of this guidance will have on our consolidated financial statements, however we do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

Share-Based Compensation

ASU 2014-12, "Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force)"

In June 2014, the FASB issued ASU No. 2014-12, which clarifies the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASI 2014-12 is effective for annual and interim periods beginning after December 15, 2015 (our fiscal 2016) with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements,

Going Concern

ASU 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern"

In August 2014, the FASB issued ASU 2014-15, which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016 (our fiscal 2017) with early adoption permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

We reviewed all other newly issued accounting pronouncements and concluded that they are either not applicable to our business or are not expected to have a material effect on the financial statements as a result of future adoption.
