Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Introduction and Basis of Presentation

Denny’s Corporation, or Denny’s or the Company, is one of America’s largest full-service restaurant chains based on number of restaurants. At March 28, 2018, the Denny's brand consisted of 1,724 restaurants, 1,542 of which were franchised/licensed restaurants and 182 of which were company operated.

Our unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Therefore, certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of the interim periods presented have been included. Such adjustments are of a normal and recurring nature. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions; however, we believe that our estimates, including those for the above-described items, are reasonable.

These interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto for the year ended December 27, 2017 and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our Annual Report on Form 10-K for the fiscal year ended December 27, 2017. The results of operations for the interim periods presented are not necessarily indicative of the results for the entire fiscal year ending December 26, 2018.

Note 2. Summary of Significant Accounting Policies

Newly Adopted Accounting Standards

Effective December 28, 2017, the first day of fiscal 2018, we adopted Accounting Standards Update 2014-09, “Revenue from Contracts with Customers (Topic 606)” and all subsequent ASUs that modified Topic 606. The new guidance clarifies the principles used to recognize revenue for all entities and requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. We elected to apply the modified retrospective method of adoption to those contracts which were not completed as of December 28, 2017. In doing so, we applied the practical expedient to aggregate all contract modifications that occurred before December 28, 2017 in determining the satisfied and unsatisfied performance obligations, the transaction price and the allocation of the transaction price to the satisfied and unsatisfied performance obligations. Results for reporting periods beginning after December 28, 2017 are presented under Topic 606. Prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under Topic 605 “Revenue Recognition.” Our transition to Topic 606 represents a change in accounting principle. See Note 3 for further information about our transition to Topic 606 and the newly required disclosures.

Effective December 28, 2017, we adopted ASU 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. The new guidance requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we adopted ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)”. The new guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we adopted ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. The new guidance clarifies the definition of a business. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we adopted ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The new guidance requires an entity to report the service cost component in the same line on the income statement as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. If a separate line item is not used, the line item used in the income statement must be disclosed. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we adopted ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting”. The new update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we early adopted ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and requires certain disclosures about stranded tax effects. Due to the immateriality of the stranded tax effects resulting from the implementation Tax Act, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings. Therefore the adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we early adopted ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. The new update clarifies certain aspects of the guidance issued in ASU 2016-01. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Effective December 28, 2017, we early adopted ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The new update better aligns an entity’s risk management activities and financial reporting for hedging relationships, simplifies the hedge accounting requirements, and improves the disclosures of hedging arrangements. The amended presentation and disclosure guidance has been applied on a prospective basis. The adoption of this guidance did not have any impact on our Consolidated Financial Statements.

Accounting Standards to be Adopted

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “Leases (Topic 842)”, which provides guidance for accounting for leases. The new guidance requires companies to recognize the assets and liabilities for the rights and obligations created by leased assets. The accounting guidance for lessors is largely unchanged. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018 (our fiscal 2019) with early adoption permitted. The guidance will be adopted using a modified retrospective approach. Based on a preliminary assessment, we expect the adoption will result in a significant increase in the assets and liabilities on our Consolidated Balance Sheets, as most of our operating lease commitments will be recognized as operating lease liabilities and right-of-use assets. We are continuing our evaluation, which may identify additional impacts this standard will have on our Consolidated Financial Statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. The new guidance replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform financial statement users of credit loss estimates. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 (our fiscal 2020) with early adoption permitted for annual and interim periods beginning after December 15, 2018 (our fiscal 2019). We do not expect the adoption of this guidance to 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 our consolidated financial statements as a result of future adoption.

Note 3. Revenues

Our revenues are derived primarily from two sales channels, which we operate as one segment: company restaurants and franchised and licensed restaurants. The following table disaggregates our revenue by sales channels and types of goods or services.



	Quarter Ended
	March 28, 2018		March 29, 2017 ⁽¹⁾
	(Dollars in thousands)
Company restaurant sales	$	101,193	$	93,779
Franchise and license revenue:
Royalties	25,165		24,544
Advertising revenue	19,310		—
Initial and other fees	1,417		484
Occupancy revenue	8,188		9,103
Franchise and license revenue	54,080		34,131
Total operating revenue	$	155,273	$	127,910


(1)	As disclosed in Note 2, prior period amounts have not been adjusted under the modified retrospective method of adoption of Topic 606.

Company Restaurant Revenue

Company restaurant revenue is recognized at the point in time when food and beverage products are sold at company restaurants. We present company restaurant sales net of sales-related taxes collected from customers and remitted to governmental taxing authorities. The adoption of Topic 606 did not impact the recognition of company restaurant sales.

Franchise Revenue

Franchise and license revenues consist primarily of royalties, advertising revenue, initial and other fees and occupancy revenue.

Our performance obligations under franchise agreements consist of a license of our brand’s symbolic intellectual property, administration of advertising programs (including local co-operatives), and other ongoing support services. These performance obligations are highly interrelated so we do not consider them to be individually distinct, and therefore account for them under Topic 606 as a single performance obligation. Revenue from franchise agreements is recognized evenly over the term of the agreement with the exception of sales-based royalties and revenue allocated to goods and services distinct from the franchise right.

Royalty and advertising revenues represent sales-based royalties that are recognized in the period in which the sales occur. Sales-based royalties are variable consideration related to our performance obligations to our franchisees to maintain the intellectual property being licensed. Under our franchise agreements, franchisee advertising contributions must be spent on marketing and related activities. The adoption of Topic 606 did not impact the recognition of royalties. Upon adoption of Topic 606, advertising revenues and expenditures are recorded on a gross basis within the Consolidated Statements of Income. Under the previous guidance of Topic 605, we recorded franchise advertising expense net of contributions from franchisees to our advertising programs, including local co-operatives. While this change materially impacts the gross amount of reported franchise and license revenue and costs of franchise and license revenue, the impact is generally an offsetting increase to both revenue and expense with little, if any, impact on operating income and net income.

Initial and other fees consist of initial, successor and assignment franchise fees (“initial franchise fees”), training fees and other franchise services fees. Initial franchise fees are billed and received upon the signing of the franchise agreement. Under Topic 606, recognition of these fees is deferred until the commencement date of the agreement and occurs over time based on the term of the underlying franchise agreement. In the event a franchise agreement is terminated, any remaining deferred fees are recognized in the period of termination. Under the previous guidance, initial franchise fees were recognized upon the opening of a franchise restaurant. Training and other franchise services fees are billed and recognized at a point in time as services are rendered. Similar to advertising revenue, upon adoption of Topic 606, other franchise services fees are recorded on a gross basis within the Consolidated Statements of Income, whereas, under previous guidance, they were netted against the related expenses.

Occupancy revenue results from leasing or subleasing restaurants to franchisees and is recognized over the term of the lease agreement.

With the exception of initial and other franchise fees, revenues are typically billed and collected on a weekly basis.

Gift Card Breakage

Under previous guidance, we recorded gift card breakage when the likelihood of redemption was remote. Breakage was recorded as a benefit to our advertising fund or reduction to other operating expenses, depending on where the gift cards were sold. Upon adoption of Topic 606, gift card breakage is recognized proportionally as redemptions occur. Our gift card breakage primarily relates to cards sold by third parties. Breakage revenue related to third party sales is recorded as advertising revenue (included as a component of franchise and license revenue) with an offsetting amount recorded as advertising expense (included as a component of costs of franchise and license revenue).

Financial Statement Impact of Adoption

The following tables summarize the impact of adopting Topic 606 on our financial statement line items as of March 28, 2018 and for the quarter ended March 28, 2018.

The following significant changes impacted our financial statement line items as of March 28, 2018 and for the quarter ended March 28, 2018:

•

Upon adoption of Topic 606, we recorded a cumulative effect adjustment related to previously recognized initial franchise fees resulting in a $21.0 million increase to deferred franchise revenue, a $15.6 million increase to opening deficit and a $5.4 million increase to deferred tax assets. The deferred franchise revenue resulting from the cumulative effect adjustment will be amortized over the remaining lives of the individual franchise agreements. Also upon adoption, we recorded a cumulative effect adjustment to recognize breakage in proportion to redemptions that occurred prior to December 28, 2017 resulting in a decrease of $0.6 million to gift card liability (a component of other current liabilities), a $0.5 million increase to accrued advertising (a component of other current liabilities) and a $0.1 million decrease to opening deficit.


•	We recognized $19.2 million of franchise and license revenue and $19.2 million of costs of franchise and license revenue resulting from the recording of advertising revenues and expenditures on a gross basis under Topic 606 versus recording these amounts on a net basis under Topic 605.


•	We recognized an additional $0.5 million of franchise and license revenue under Topic 606 than we would have recognized under Topic 605, resulting from the timing of recognition of initial franchise fees.


•	We recognized $0.5 million of franchise and license revenue and $0.5 million of costs of franchise and license revenue resulting from the recording of other franchise services fees on a gross basis under Topic 606 versus recording these amount on a net basis under Topic 605.

Contract Balances

Contract balances related to contracts with customers consists of receivables, deferred franchise revenue and deferred gift card revenue. See note 4 for details on our receivables.

Deferred franchise revenue consists primarily of the unamortized portion of initial franchise fees that are currently being amortized into revenue and amounts related to development agreements and unopened restaurants that will begin amortizing into revenue when the related restaurants are opened. Deferred franchise revenue represents our remaining performance obligations to our franchisees, excluding amounts of variable consideration related to sale-based royalties and advertising. The components of the change in deferred franchise revenue are as follows:



	(In thousands)

Deferred gift card liabilities consist of the unredeemed portion of gift cards sold in company restaurants and at third party locations. We recognize gift card revenue when a gift card is redeemed in one of our company restaurants. Gift card breakage is recognized proportionally as redemptions occur. The balance of deferred gift card liabilities represents our remaining performance obligations to our customers. The balance of deferred gift card liabilities as of March 28, 2018 and December 27, 2017 was $4.4 million and $6.5 million, respectively. During the quarter ended March 28, 2018, we recognized revenue of $0.7 million from gift card redemptions.

Note 9. Long-Term Debt

Denny's Corporation and certain of its subsidiaries have a credit facility consisting of a five-year $400 million senior secured revolver (with a $30 million letter of credit sublimit). The credit facility includes an accordion feature that would allow us to increase the size of the revolver to $450 million. As of March 28, 2018, we had outstanding revolver loans of $282.0 million and outstanding letters of credit under the senior secured revolver of $21.2 million. These balances resulted in availability of $96.8 million under the credit facility. Prior to considering the impact of our interest rate swaps, described below, the weighted-average interest rate on outstanding revolver loans was 3.76% and 3.42% as of March 28, 2018 and December 27, 2017, respectively. Taking into consideration our interest rate swaps, the weighted-average interest rate of outstanding revolver loans was 3.53% and 3.32% as of March 28, 2018 and December 27, 2017, respectively.

A commitment fee is paid on the unused portion of the credit facility and was 0.30% as of March 28, 2018. Borrowings under the credit facility bear a tiered interest rate, which is based on the Company’s consolidated leverage ratio and was set at LIBOR plus 200 basis points as of March 28, 2018. The maturity date for the credit facility is October 26, 2022.

The credit facility is available for working capital, capital expenditures and other general corporate purposes. The credit facility is guaranteed by the Company and its material subsidiaries and is secured by assets of the Company and its subsidiaries, including the stock of the Company's subsidiaries. It includes negative covenants that are usual for facilities and transactions of this type. The credit facility also includes certain financial covenants with respect to a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio. We were in compliance with all financial covenants as of March 28, 2018.

Interest Rate Hedges

We have interest rate swaps to hedge a portion of the forecasted cash flows of our floating rate debt. We designated the interest rate swaps as cash flow hedges of our exposure to variability in future cash flows attributable to payments of LIBOR due on specific notional amounts.

Under the interest rate swaps, we pay a fixed rate on the notional amount in addition to the current interest rate as determined by our consolidated leverage ratio in effect at the time. A summary of our interest rate swaps as of March 28, 2018 is as follows:



Trade Date	Effective Date	Maturity Date	Notional Amount			Fixed Rate
			(In thousands)
April 30, 2013	March 31, 2015	March 29, 2018	$	120,000		1.13	%
March 20, 2015	March 29, 2018	March 31, 2025	120,000			2.44	%
October 1, 2015	March 29, 2018	March 31, 2026	50,000			2.46	%
February 15, 2018	March 31, 2020	December 31, 2033	80,000		⁽¹⁾	3.19	%


(1)	The notional amount of the swaps entered into on February 15, 2018 increases annually beginning September 30, 2020 until they reach the maximum notional amount of $425.0 million on September 28, 2029.

As of March 28, 2018, the fair value of the interest rate swaps was a net liability of $6.4 million, which is comprised of assets of $1.7 million recorded as a component of other noncurrent assets and liabilities of $8.1 million recorded as a component of other noncurrent liabilities in our Condensed Consolidated Balance Sheets. See Note 15 for the amounts recorded in accumulated other comprehensive loss related to the interest rate swaps.

Note 10. Defined Benefit Plans

The components of net periodic benefit cost for our defined benefit plans, included as a component of general and administrative costs, were as follows:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Interest cost	$	19	$	21
Amortization of net loss	28		23
Net periodic benefit cost	$	47	$	44

We made contributions of less than $0.1 million to our defined benefit plans during both the quarter ended March 28, 2018 and the quarter ended March 29, 2017. We expect to contribute $0.1 million to our defined benefit plans over the remainder of fiscal 2018.

Additional minimum pension liability, net of tax, of $1.0 million related to our defined benefit plans is reported as a component of accumulated other comprehensive loss in our Condensed Consolidated Statement of Shareholders’ Equity as of both March 28, 2018 and December 27, 2017, respectively.

Note 11. Share-Based Compensation

Total share-based compensation cost included as a component of net income was as follows:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Performance share awards	$	1,078	$	1,940
Restricted stock units for board members	272		33
Total share-based compensation	$	1,350	$	1,973

Performance Share Units

During the quarter ended March 28, 2018, we granted certain employees approximately 0.2 million performance share units that vest based on the total shareholder return (“TSR”) of our common stock compared to the TSRs of a group of peer companies and 0.3 million performance share units that vest based on our Adjusted EPS growth rate versus plan, as defined under the terms of the award. As the TSR based performance share units contain a market condition, a Monte Carlo valuation was used to determine the grant date fair value of $18.17 per share. The performance share units based on the Adjusted EPS growth rate have a grant date fair value of $15.93 per share, the market value of our common stock on the date of grant. The awards granted to our named executive officers also contain a performance condition based on the attainment of an operating measure for the fiscal year ended December 26, 2018. The performance period for these performance share units is the three year fiscal period beginning December 28, 2017 and ending December 30, 2020. They will vest and be earned (from 0% to 150% of the target award for each such increment) at the end of the performance period.

During the quarter ended March 28, 2018, we issued 0.2 million shares of common stock related to vested performance share units. In addition 0.3 million shares of common stock were deferred and 0.1 million shares of common stock were withheld in lieu of taxes related to vested performance share units.

As of March 28, 2018, we had approximately $13.3 million of unrecognized compensation cost related to all unvested performance share awards outstanding, which is expected to be recognized over a weighted average of 2.2 years.

Restricted Stock Units for Board Members

As of March 28, 2018, we had approximately $0.2 million of unrecognized compensation cost related to all unvested restricted stock unit awards outstanding, which is expected to be recognized over a weighted average of 0.8 years.

Note 12. Income Taxes

The effective income tax rate was 15.8% for the quarter ended March 28, 2018 compared to 36.2% for the prior year period. The 2018 period was impacted by the Tax Act. In addition, the 2018 period benefited from a 4.7% discrete item relating to share-based compensation. The Tax Act reduces the U.S. statutory tax rate from 35% to 21% for years after 2017. We revalued our deferred taxes during fiscal 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are realized. The implementation of the Tax Act resulted in certain stranded tax effects in accumulated other comprehensive income. Due to the immateriality of the stranded tax effects, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings.

Note 13. Net Income Per Share

The amounts used for the basic and diluted net income per share calculations are summarized below:



	Quarter Ended

Note 15. Shareholders' Equity

Share Repurchase

Our credit facility permits the purchase of Denny’s stock and the payment of cash dividends subject to certain limitations. In October 2017, our Board of Directors approved a share repurchase program authorizing us to repurchase up to $200 million of our common stock (in addition to prior authorizations). Under this program, we may, from time to time, purchase shares in the open market (including pre-arranged stock trading plans in accordance with the guidelines specified in Rule 10b5-1 under the Securities Exchange Act of 1934, as amended) or in privately negotiated transactions, subject to market and business conditions.

During the quarter ended March 28, 2018, we repurchased 1.1 million shares of our common stock for approximately $16.2 million. This brings the total amount repurchased under the current repurchase program to 1.3 million shares of our common stock for approximately $19.9 million, leaving approximately $180.1 million that can be used to repurchase our common stock under this program as of March 28, 2018. Repurchased shares are included as treasury stock in our Condensed Consolidated Balance Sheets and our Condensed Consolidated Statement of Shareholders' Equity.

(1)	Before-tax amount related to our Other Defined Benefit Plans that was reclassified from accumulated other comprehensive loss and included as a component of pension expense within general and administrative expenses in our Condensed Consolidated Statements of Income during the quarter ended March 28, 2018. See Note 10 for additional details.

(2)

Amounts reclassified from accumulated other comprehensive loss into income represent payments either received from or made to the counterparty for the effective portions of the interest rate swaps. These amounts are included as a component of interest expense, net in our Condensed Consolidated Statements of Income. We expect to make payments to the counterparty and reclassify approximately $1.0 million from accumulated other comprehensive loss related to our interest rate swaps during the next twelve months. See Note 9 for additional details.

Note 16. Commitments and Contingencies

We have guarantees related to certain franchisee loans. Payments under these guarantees would result from the inability of a franchisee to fund required payments when due. Through March 28, 2018, no events had occurred that caused us to make payments under these guarantees. There were $4.7 million and $5.1 million of loans outstanding under these programs as of March 28, 2018 and December 27, 2017, respectively. As of March 28, 2018, the maximum amount payable under the loan guarantees was $1.1 million. As a result of these guarantees, we have recorded liabilities of less than $0.1 million as of both March 28, 2018 and December 27, 2017, which are included as a component of other noncurrent liabilities in our Condensed Consolidated Balance Sheets and other nonoperating expense in our Condensed Consolidated Statements of Income.

There are various claims and pending legal actions against or indirectly involving us, incidental to and arising out of the ordinary course of the business. In the opinion of management, based upon information currently available, the ultimate liability with respect to these proceedings and claims will not materially affect the Company's consolidated results of operations or financial position.

Note 17. Subsequent Events

We performed an evaluation of subsequent events and determined that no events required disclosure.

Factors Impacting Comparability

Impact of New Revenue Recognition Standard

Effective December 28, 2017, the first day of fiscal 2018, the Company adopted Accounting Standards Update 2014-09, “Revenue from Contracts with Customers (Topic 606)” and all subsequent ASUs that modified Topic 606 on a modified retrospective basis. Results for reporting periods beginning after December 28, 2017 are presented under Topic 606. Prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under Topic 605 “Revenue Recognition.”

The most significant effects of the new guidance on the comparability of our results of operations between 2018 and 2017 include the following:

•

Under Topic 606, advertising revenues and expenditures are recorded on a gross basis within the Consolidated Statements of Income. Under the previous guidance of Topic 605, we recorded franchise advertising expense net of contributions from franchisees to our advertising programs, including local co-operatives. While this change materially impacts the gross amount of reported franchise and license revenue and costs of franchise and license revenue, the impact is generally an offsetting increase to both revenue and expense with little, if any, impact on operating income and net income. Similarly, upon adoption, other franchise services fees are recorded on a gross basis within the Consolidated Statements of Income, whereas, under previous guidance, they were netted against the related expenses.

•

Under Topic 606, recognition of initial franchise fees is deferred until the commencement date of the agreement and occurs over time based on the term of the underlying franchise agreement. In the event a franchise agreement is terminated, any remaining deferred fees are recognized in the period of termination. Under the previous guidance, initial franchise fees were recognized upon the opening of a franchise restaurant. The effect of the required deferral of initial franchise fees received in a given year is mitigated by the recognition of revenue from fees received in prior periods.

•

Under previous guidance, we recorded gift card breakage when the likelihood of redemption was remote. Breakage was recorded as a benefit to our advertising fund or reduction to other operating expenses, depending on where the gift cards were sold. Under Topic 606, gift card breakage is recognized proportionally as redemptions occur. Our gift card breakage primarily relates to cards sold by third parties. Breakage revenue related to third party sales is recorded as advertising revenue (included as a component of franchise and license revenue) with an offsetting amount recorded as advertising expense (included as a component of costs of franchise and license revenue).

See Note 2 and Note 3 for information on the implementation of Topic 606 and its impact on our Consolidated Financial Statements.

Company Restaurant Operations

During the quarter ended March 28, 2018, company restaurant sales increased $7.4 million, or 7.9%, primarily resulting from a nine equivalent unit increase in company restaurants as compared to the prior year period and a 3.2% increase in company same-store sales.

Total costs of company restaurant sales as a percentage of company restaurant sales increased to 85.8% for the quarter from 83.0% in the prior year period.

Product costs decreased to 24.6% from 24.7%. Payroll and benefits increased to 40.7% from 39.9% primarily due to a 0.6 percentage point increase in labor costs. The increase in labor costs primarily resulted from minimum wage increases. Occupancy costs increased to 5.6% from 5.0% primarily due to increases in general liability insurance costs, as the prior year included $0.4 million in favorable claims development.

Other operating expenses were comprised of the following amounts and percentages of company restaurant sales:



	Quarter Ended
	March 28, 2018				March 29, 2017
	(Dollars in thousands)
Utilities	$	3,405	3.4	%	$	3,053	3.3	%

Other operating expenses	$	15,050	14.9	%	$	12,571	13.4	%

The increase in other direct costs was primarily related to a $0.7 million increase in third party delivery fees related to Denny's On Demand.

Franchise Operations

Franchise and license revenue and costs of franchise and license revenue were comprised of the following amounts and percentages of franchise and license revenue for the periods indicated:



	Quarter Ended
	March 28, 2018				March 29, 2017
	(Dollars in thousands)
Royalties	$	25,165	46.5	%	$	24,544	71.9	%
Advertising revenue	19,310		35.7	%	—		—	%
Initial and other fees	1,417		2.6	%	484		1.4	%
Occupancy revenue	8,188		15.1	%	9,103		26.7	%
Franchise and license revenue	$	54,080	100.0	%	$	34,131	100.0	%

Advertising costs	$	19,310	35.7	%	$	525	1.5	%
Occupancy costs	$	5,829	10.8	%	$	6,506	19.1	%
Other direct costs	3,417		6.3	%	2,715		8.0	%
Costs of franchise and license revenue	$	28,556	52.8	%	$	9,746	28.6	%

During the quarter ended March 28, 2018, royalties increased $0.6 million, or 2.5%, primarily resulting from a 1.2% increase in domestic same-store sales and a higher average royalty rate as compared to the prior year period, partially offset by an 18 equivalent unit decrease in franchised and licensed restaurants. The increases in initial and other fees and advertising revenue primarily resulted from the implementation of Topic 606 related to revenue recognition. The adoption of this guidance resulted in the recognition of approximately $0.5 million of initial fees that would not have been recognized under the previous guidance and $0.4 million of other franchise fees that are now required to be presented on a gross basis, instead of a net basis as previously presented. Advertising revenue and costs are also now required to be presented on a gross basis, instead of a net basis as previously presented. The decrease in occupancy revenue of $0.9 million, or 10.1%, was primarily the result of lease expirations.

Costs of franchise and license revenue increased $18.8 million, or 193.0%. The increase in advertising costs related to the implementation of Topic 606, as advertising revenue is no longer netted with advertising expense. Occupancy costs decreased $0.7 million, or 10.4%, primarily resulting from lease expirations. The increase in other direct costs primarily related to the implementation of Topic 606, as certain other franchise expenses are no longer netted with the related fees received from franchisees. As a result, costs of franchise and license revenue as a percentage of franchise and license revenue increased to 52.8% from 28.6%.

Other Operating Costs and Expenses

Other operating costs and expenses such as general and administrative expenses and depreciation and amortization expense relate to both company and franchise operations.

General and administrative expenses were comprised of the following:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Share-based compensation	$	1,350	$	1,973
Other general and administrative expenses	15,210		15,536
Total general and administrative expenses	$	16,560	$	17,509

Other general and administrative expenses decreased by $0.3 million primarily resulting from a $0.7 million decrease related to market valuation changes in our non-qualified deferred compensation plan liabilities in the current year period and a $0.6 million decrease in professional fees. Offsetting losses on the underlying plan investments are included as a component of other

non-operating income, net. These decreases were partially offset by a $1.0 million increase related to investments in personnel and increased incentive compensation.

Depreciation and amortization was comprised of the following:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Depreciation of property and equipment	$	4,480	$	4,217
Amortization of capital lease assets	1,071		994
Amortization of intangible and other assets	963		525
Total depreciation and amortization expense	$	6,514	$	5,736

The increase in amortization of intangible and other assets was primarily due to the increase in reacquired franchise rights related to acquisitions of franchised restaurants during the current and prior year.

Operating (gains), losses and other charges, net were comprised of the following:



	Quarter Ended
	March 28, 2018			March 29, 2017
	(In thousands)
Software implementation costs	—			2,124
Gains on sales of assets and other, net	(37		)	(1,440		)
Restructuring charges and exit costs	360			99
Impairment charges	37			—
Operating (gains), losses and other charges, net	$	360		$	783

Restructuring charges and exit costs were comprised of the following:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Exit costs	$	24	$	31
Severance and other restructuring charges	336		68
Total restructuring and exit costs	$	360	$	99

Operating income was $16.4 million for the quarter ended March 28, 2018 compared to $16.3 million for the quarter ended March 29, 2017.

Interest expense, net was comprised of the following:



	Quarter Ended
	March 28, 2018			March 29, 2017
	(In thousands)
Interest on credit facilities	$	2,590		$	1,498
Interest on interest rate swaps	(140		)	108
Interest on capital lease liabilities	1,604			1,393
Letters of credit and other fees	320			280
Interest income	(29		)	(15		)
Total cash interest	4,345			3,264
Amortization of deferred financing costs	152			148
Interest accretion on other liabilities	128			129
Total interest expense, net	$	4,625		$	3,541

Interest expense, net increased by $1.1 million primarily due to increases in the balance of our credit facility and related interest rates.

Other nonoperating (income) expense, net was expense of $0.2 million for the quarter ended March 28, 2018, resulting primarily from losses on deferred compensation plan investments, compared to income of $0.4 million for the prior year period, resulting primarily from gains on deferred compensation plan investments.

Provision for income taxes was $1.8 million for the quarter ended March 28, 2018 compared to $4.7 million for the quarter ended March 29, 2017. The effective tax rate was 15.8% compared to 36.2%. The 2018 period was impacted by the Tax Act. In addition, the 2018 period benefited from a 4.7% discrete item relating to share-based compensation. The Tax Act reduces the U.S. statutory tax rate from 35% to 21% for years after 2017. We revalued our deferred taxes during fiscal 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are realized. The implementation of the Tax Act resulted in certain stranded tax effects in accumulated other comprehensive income. Due to the immateriality of the stranded tax effects, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings. We expect the 2018 fiscal year effective tax rate to be between 16% and 19%. The annual effective tax rate cannot be determined until the end of the fiscal year; therefore, the actual rate could differ from our current estimates.

Net income was $9.8 million for the quarter ended March 28, 2018 compared with $8.4 million for the quarter ended March 29, 2017.

Liquidity and Capital Resources

Our primary sources of liquidity and capital resources are cash generated from operations and borrowings under our credit facility (as described below). Principal uses of cash are operating expenses, capital expenditures and the repurchase of shares of our common stock.

The following table presents a summary of our sources and uses of cash and cash equivalents for the periods indicated:



	Quarter Ended
	March 28, 2018			March 29, 2017
	(In thousands)
Net cash provided by operating activities	$	3,450		$	8,021
Net cash used in investing activities	(13,637		)	(6,963		)
Net provided by cash (used in) financing activities	9,123			(1,910		)
Decrease in cash and cash equivalents	$	(1,064	)	$	(852	)

Net cash flows provided by operating activities were $3.5 million for the quarter ended March 28, 2018 compared to $8.0 million for the quarter ended March 29, 2017. The decrease in cash flows provided by operating activities was primarily due to the reduction in payables during the quarter ended March 28, 2018. We believe that our estimated cash flows from operations for 2018, combined with our capacity for additional borrowings under our credit facility, will enable us to meet our anticipated cash requirements and fund capital expenditures over the next 12 months.

Net cash flows used in investing activities were $13.6 million for the quarter ended March 28, 2018. These cash flows were primarily comprised of capital expenditures of $4.1 million, acquisitions of restaurants of $8.4 million and note receivable issuances of $1.9 million. Cash flows for acquisitions included $7.9 million for the acquisition of five franchised restaurants and $0.5 million related to a prior year acquisition. Net cash flows used in investing activities were $7.0 million for the quarter ended March 29, 2017. These cash flows were primarily comprised of capital expenditures of $3.0 million, acquisitions of restaurants and real estate of $3.8 million and note receivable issuances of $1.0 million. Cash flows for acquisitions included $2.4 million of real estate associated with relocating a high-performing company restaurant due to the impending loss of property control and $1.4 million for the reacquisition of three franchised restaurants.

Our principal capital requirements have been largely associated with the following:



	Quarter Ended
	March 28, 2018		March 29, 2017
	(In thousands)
Facilities	$	2,208	$	1,767
New construction	205		109
Remodeling	126		230
Information technology	215		86
Other	1,394		825
Capital expenditures (excluding acquisitions)	$	4,148	$	3,017

Capital expenditures and acquisitions for fiscal 2018 are expected to be approximately $33 to $35 million, including the above mentioned acquisition of franchised restaurants, a planned company restaurant opening later in the year, remodels from recent franchise acquisitions, restaurant offsets and on-going maintenance capital.

Cash flows provided by financing activities were $9.1 million for the quarter ended March 28, 2018, which included net long-term debt borrowings of $22.2 million, partially offset by cash payments for stock repurchases of $15.7 million. Cash flows used in financing activities were $1.9 million for the quarter ended March 29, 2017, which included cash payments for stock repurchases of $11.7 million, partially offset by net long-term debt borrowings of $10.7 million.

Our working capital deficit was $44.7 million at March 28, 2018 compared to $53.6 million at December 27, 2017. The decrease in working capital deficit was primarily related to the payout of accrued incentive compensation and accrued advertising during the quarter ended March 28, 2018. We are able to operate with a substantial working capital deficit because (1) restaurant operations and most food service operations are conducted primarily on a cash (and cash equivalent) basis with a low level of accounts receivable, (2) rapid turnover allows a limited investment in inventories, and (3) accounts payable for food, beverages and supplies usually become due after the receipt of cash from the related sales.

Credit Facility

As of March 28, 2018, we had outstanding revolver loans of $282.0 million and outstanding letters of credit under the senior secured revolver of $21.2 million. These balances resulted in availability of $96.8 million under the credit facility. The credit facility includes an accordion feature that would allow us to increase the size of the revolver to $450 million. Prior to considering the impact of our interest rate swaps, described below, the weighted-average interest rate on outstanding revolver loans was 3.76% as of March 28, 2018. Taking into consideration our interest rate swaps, the weighted-average interest rate of outstanding revolver loans was 3.53% as of March 28, 2018.

Contractual Obligations

Other than the items discussed below, there have been no material changes in our total obligations during the quarter ended March 28, 2018 outside of the normal course of our business. See Management's Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 27, 2017 for information concerning other future contractual obligations and commitments.

(a)	Interest obligations represent payments related to our long-term debt outstanding at March 28, 2018. For long-term debt with variable rates, we have used the rate applicable at March 28, 2018 to project interest over the periods presented in the table above, taking into consideration the impact of the interest rate swaps for the applicable periods.

Implementation of New Accounting Standards

Information regarding the implementation of new accounting standards is incorporated by reference from Note 2 to our unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As of March 28, 2018, interest rate swaps effectively increased our ratio of fixed rate debt from approximately 10% of total debt to approximately 48% of total debt. The current swap terminated on March 29, 2018 and two new swaps became effective. These swaps increase our ratio of fixed rate debt to approximately 64% of total debt. We expect to reclassify approximately $1.0 million from accumulated other comprehensive loss related to our interest rate swaps during the next twelve months. This amount will be included as a component of interest expense in our Condensed Consolidated Statements of Income. For additional information related to our interest rate swaps, including changes in the fair value, refer to Notes 8, 9 and 15 to our unaudited condensed consolidated financial statements in Part I, Item 1 of this report.

Based on the levels of borrowings under the credit facility at March 28, 2018, if interest rates changed by 100 basis points, our annual cash flow and income before taxes would change by approximately $1.1 million. This computation is determined by considering the impact of hypothetical interest rates on the variable rate portion of the credit facility at March 28, 2018, taking into consideration the interest rate swaps that will be in effect during the annual period. However, the nature and amount of our borrowings may vary as a result of future business requirements, market conditions and other factors.

With the exception of the items noted above, there have been no material changes in our quantitative and qualitative market risks since the prior reporting period.

Item 4. Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our management conducted an evaluation (under the supervision and with the participation of our President and Chief Executive Officer, John C. Miller, and our Executive Vice President, Chief Administrative Officer and Chief Financial Officer, F. Mark Wolfinger) as of the end of the period covered by this Quarterly Report on Form 10-Q, of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. Based on that evaluation, Messrs. Miller and Wolfinger each concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and (ii) is accumulated and communicated to our management, including Messrs. Miller and Wolfinger, as appropriate to allow timely decisions regarding required disclosure.

During the first quarter of 2018, we implemented new controls in connection with our adoption of the Accounting Standards Updates related to Topic 606, Revenue from Contracts with Customers. There were no significant changes to our internal control over financial reporting due to the adoption of the new standards. There were no other changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Introduction and Basis of Presentation	Mar. 28, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation Denny’s Corporation, or Denny’s or the Company, is one of America’s largest full-service restaurant chains based on number of restaurants. At March 28, 2018, the Denny's brand consisted of 1,724 restaurants, 1,542 of which were franchised/licensed restaurants and 182 of which were company operated. Our unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Therefore, certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of the interim periods presented have been included. Such adjustments are of a normal and recurring nature. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions; however, we believe that our estimates, including those for the above-described items, are reasonable. These interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto for the year ended December 27, 2017 and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our Annual Report on Form 10-K for the fiscal year ended December 27, 2017. The results of operations for the interim periods presented are not necessarily indicative of the results for the entire fiscal year ending December 26, 2018.

Summary of Significant Accounting Policies	Mar. 28, 2018
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Newly Adopted Accounting Standards Effective December 28, 2017, the first day of fiscal 2018, we adopted Accounting Standards Update 2014-09, “Revenue from Contracts with Customers (Topic 606)” and all subsequent ASUs that modified Topic 606. The new guidance clarifies the principles used to recognize revenue for all entities and requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. We elected to apply the modified retrospective method of adoption to those contracts which were not completed as of December 28, 2017. In doing so, we applied the practical expedient to aggregate all contract modifications that occurred before December 28, 2017 in determining the satisfied and unsatisfied performance obligations, the transaction price and the allocation of the transaction price to the satisfied and unsatisfied performance obligations. Results for reporting periods beginning after December 28, 2017 are presented under Topic 606. Prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under Topic 605 “Revenue Recognition.” Our transition to Topic 606 represents a change in accounting principle. See Note 3 for further information about our transition to Topic 606 and the newly required disclosures. Effective December 28, 2017, we adopted ASU 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. The new guidance requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we adopted ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)”. The new guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we adopted ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. The new guidance clarifies the definition of a business. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we adopted ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The new guidance requires an entity to report the service cost component in the same line on the income statement as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. If a separate line item is not used, the line item used in the income statement must be disclosed. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we adopted ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting”. The new update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we early adopted ASU 2018-02, “Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and requires certain disclosures about stranded tax effects. Due to the immateriality of the stranded tax effects resulting from the implementation Tax Act, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings. Therefore the adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we early adopted ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. The new update clarifies certain aspects of the guidance issued in ASU 2016-01. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Effective December 28, 2017, we early adopted ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The new update better aligns an entity’s risk management activities and financial reporting for hedging relationships, simplifies the hedge accounting requirements, and improves the disclosures of hedging arrangements. The amended presentation and disclosure guidance has been applied on a prospective basis. The adoption of this guidance did not have any impact on our Consolidated Financial Statements. Accounting Standards to be Adopted In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “Leases (Topic 842)”, which provides guidance for accounting for leases. The new guidance requires companies to recognize the assets and liabilities for the rights and obligations created by leased assets. The accounting guidance for lessors is largely unchanged. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018 (our fiscal 2019) with early adoption permitted. The guidance will be adopted using a modified retrospective approach. Based on a preliminary assessment, we expect the adoption will result in a significant increase in the assets and liabilities on our Consolidated Balance Sheets, as most of our operating lease commitments will be recognized as operating lease liabilities and right-of-use assets. We are continuing our evaluation, which may identify additional impacts this standard will have on our Consolidated Financial Statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. The new guidance replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform financial statement users of credit loss estimates. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 (our fiscal 2020) with early adoption permitted for annual and interim periods beginning after December 15, 2018 (our fiscal 2019). We do not expect the adoption of this guidance to 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 our consolidated financial statements as a result of future adoption.

Income Taxes	Mar. 28, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate was 15.8% for the quarter ended March 28, 2018 compared to 36.2% for the prior year period. The 2018 period was impacted by the Tax Act. In addition, the 2018 period benefited from a 4.7% discrete item relating to share-based compensation. The Tax Act reduces the U.S. statutory tax rate from 35% to 21% for years after 2017. We revalued our deferred taxes during fiscal 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are realized. The implementation of the Tax Act resulted in certain stranded tax effects in accumulated other comprehensive income. Due to the immateriality of the stranded tax effects, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings.

Commitments and Contingencies	Mar. 28, 2018
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We have guarantees related to certain franchisee loans. Payments under these guarantees would result from the inability of a franchisee to fund required payments when due. Through March 28, 2018, no events had occurred that caused us to make payments under these guarantees. There were $4.7 million and $5.1 million of loans outstanding under these programs as of March 28, 2018 and December 27, 2017, respectively. As of March 28, 2018, the maximum amount payable under the loan guarantees was $1.1 million. As a result of these guarantees, we have recorded liabilities of less than $0.1 million as of both March 28, 2018 and December 27, 2017, which are included as a component of other noncurrent liabilities in our Condensed Consolidated Balance Sheets and other nonoperating expense in our Condensed Consolidated Statements of Income. There are various claims and pending legal actions against or indirectly involving us, incidental to and arising out of the ordinary course of the business. In the opinion of management, based upon information currently available, the ultimate liability with respect to these proceedings and claims will not materially affect the Company's consolidated results of operations or financial position.
