(1)    Basis of Presentation

Basis of Presentation

Wingstop Inc., through its primary operating subsidiary, Wingstop Restaurants Inc. (“WRI”), collectively referred to as the “Company”, is in the business of franchising and operating Wingstop restaurants. As of March 31, 2018, 1,021 franchised restaurants were in operation domestically, and 112 international franchised restaurants were in operation across eight countries. As of March 31, 2018, the Company owned and operated 24 restaurants.

The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Consequently, financial information and disclosures normally included in financial statements prepared annually in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Balance sheet amounts are as of March 31, 2018 and December 30, 2017 and operating results are for the thirteen weeks endedMarch 31, 2018 and April 1, 2017.

In the Company’s opinion, all necessary adjustments have been made for the fair presentation of the results of the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year. The accompanying interim unaudited consolidated financial statements should be read in conjunction with the audited financial statements and the related notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 30, 2017.

The Company uses a 52/53-week fiscal year that ends on the last Saturday of the calendar year. Fiscal years 2018 and 2017 have 52 weeks.

The Company has reclassified certain prior period amounts due to the adoption of ASU 2014-09 and ASU 2016-18, as defined below.

Advertising Fund

The Company administers the Wingstop Restaurants Advertising Fund (“Ad Fund”), which is used for various forms of advertising for the Wingstop brand. Advertising fund contributions and expenditures are reported on a gross basis in the Consolidated Statements of Operations, which are largely offsetting and therefore do not significantly impact our reported net income. Advertising expenses incurred by company-owned restaurants are included within cost of sales in the Consolidated Statements of Operations. Administrative expenses of the Ad Fund, such as administrative support services and compensation expenses of employees that provide services directly to the Ad Fund, are included in selling, general and administrative expenses (“SG&A”) in the Consolidated Statements of Operations.

The advertising fund contribution collected from Wingstop restaurant franchisees and company-owned and operated restaurants is equal to 3% of gross sales. For the thirteen weeks endedMarch 31, 2018 and April 1, 2017 the Company contributed $1.0 million and $2.9 million, respectively, for the purpose of supplementing the national advertising campaign, which were included in advertising expenses in the Consolidated Statements of Operations.

The Company consolidates and reports all assets and liabilities of the advertising fund as restricted assets of the advertising fund and liabilities of the advertising fund within current assets and current liabilities, respectively, in the Consolidated Balance Sheets. The assets and liabilities of the advertising fund consist primarily of cash, receivables, accrued expenses, other liabilities and any cumulative surplus related to the Ad Fund. Under the Company’s franchise agreements, contributions to the Ad Fund are restricted to advertising, public relations, merchandising, similar activities, and administrative expenses to increase sales and further enhance the public reputation of the Wingstop brand. The aforementioned administrative expenses may also include personnel expenses and allocated costs incurred by the Company which are directly associated with administering the advertising fund, as outlined in the provisions of the franchise agreements. Total cash balances related to the Ad Fund as of March 31, 2018 and December 30, 2017 were $3.7 million and $2.3 million, respectively.

Recently Issued Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to

recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 will be effective beginning in the first quarter of 2019. Early adoption of ASU 2016-02 as of its issuance is permitted. This new guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We anticipate implementing the standard by taking advantage of the practical expedient option. The discounted minimum remaining rental payments will be the starting point for determining the right-of-use asset and lease liability. We expect that adoption of the new guidance will have a material impact on our consolidated balance sheets due to recognition of the right-of-use asset and lease liability related to our current operating leases. The process of evaluating the full impact of the new guidance on our consolidated financial statements and disclosures is ongoing, but we anticipate the initial evaluation of the impact will be completed in fiscal 2018.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). ASU 2018-05 provides guidance on accounting for the income tax effects of the Tax Cuts and Jobs Act of 2017 (the “Act”), which impacts U.S. corporate tax rates, business-related exclusions, and deductions and credits. The Act also has tax consequences for many companies that operate internationally. The guidance in ASU 2018-05 addresses situations in which the accounting for certain income tax effects of the Act is incomplete by the time financial statements are issued for the reporting period that includes the enactment date of December 22, 2017. The new guidance requires companies to report provisional amounts if a reasonable estimate of the tax impact can be determined. If a provisional amount cannot be reasonably determined, the entity should continue to apply ASC Topic 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted.

The Company will continue to analyze additional information and guidance related to the Act as supplemental legislation, regulatory guidance, or evolving technical interpretations become available. The final impacts may differ from the recorded amounts as of March 31, 2018, and we will continue to refine such amounts within the measurement period provided by Staff Accounting Bulletin No. 118. We expect to complete our analysis no later than the fourth quarter of 2018.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance. The new guidance provides a single framework in which revenue is required to be recognized to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services.

The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting each prior reporting period presented and a cumulative effect adjustment, which was recorded as of the first day of 2016. The adoption changed the timing of recognition of initial franchise fees, development fees, territory fees for our international business and renewal and transfer fees, as well as the reporting of advertising fund contributions and related expenditures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that restricted cash and cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and a retrospective transition method is required. The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting the Statement of Cash Flows for each prior period presented.

(2)    Earnings per Share

Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the calculation of diluted earnings per share, the basic weighted average number of shares is increased by the dilutive effect of stock options and restricted stock units, determined using the treasury stock method.

WINGSTOP INC. AND SUBSIDIARIES

Basic weighted average shares outstanding is reconciled to diluted weighted average shares outstanding as follows (in thousands):

	Thirteen Weeks Ended
	March 31, 2018	April 1, 2017
Basic weighted average shares outstanding	29,116	28,895
Dilutive shares	387	441
Diluted weighted average shares outstanding	29,503	29,336

For the thirteen weeks endedMarch 31, 2018 and April 1, 2017, respectively, approximately 57,000 and 62,000 equity awards were excluded from the dilutive earnings per share calculation because the effect would have been anti-dilutive.

(3)    Dividends

On January 30, 2018, the Company’s Board of Directors declared a special cash dividend of $3.17 per share, which was paid on February 14, 2018 to its holders of common stock of record as of February 9, 2018, totaling $92.7 million. On February 22, 2018, the Company’s Board of Directors declared a quarterly dividend of $0.07 per share of common stock for stockholders of record as of March 9, 2018, which was paid on March 23, 2018, totaling $2.1 million.

Subsequent to the first quarter, on May 3, 2018, the Company’s Board of Directors approved a quarterly dividend of $0.07 per share of common stock for stockholders of record as of June 4, 2018, to be paid on June 18, 2018, totaling approximately $2.1 million.

(4)    Fair Value Measurements

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. Assets and liabilities are classified using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value as follows:

Level 1 — Unadjusted quoted prices for identical instruments traded in active markets.

Level 2 — Observable market-based inputs or unobservable inputs corroborated by market data.

Level 3 — Unobservable inputs reflecting management’s estimates and assumptions.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short-term nature. Fair value of debt is determined on a non-recurring basis, which results are summarized as follows (in thousands):

	Fair Value Hierarchy	March 31, 2018				December 30, 2017
		Carrying Value (2)		Fair Value		Carrying Value (2)		Fair Value
Senior Secured Credit Facility:
Term loan facility (1)	Level 2	$	98,750	$	98,750	$	64,750	$	64,750
Revolving credit facility (1)	Level 2	$	124,608	$	124,608	$	69,000	$	69,000

⁽¹⁾ The fair value of long-term debt was estimated using available market information.

⁽²⁾ Excluding issuance costs netted on the Consolidated Balance Sheet.

The Company also measures certain non-financial assets at fair value on a non-recurring basis, primarily long-lived assets, intangible assets and goodwill, in connection with our periodic evaluations of such assets for potential impairment.

(5)Income Taxes

Income tax expense and the effective tax rate were $1.7 million and 21.2%, respectively, for the thirteen weeks endedMarch 31, 2018, and $1.0 million and 13.4%, respectively, for the thirteen weeks endedApril 1, 2017.

Income tax expense for the thirteen weeks endedMarch 31, 2018 includes $0.4 million in tax benefits resulting from the recognition of excess tax benefits from stock-based compensation in income tax expense compared to $1.7 million of excess tax benefits in the prior year period. This benefit was partially affected by the reduction in the federal statutory rate for thirteen weeks endedMarch 31, 2018 from 35% to 21% effective the first day of fiscal 2018.

On January 30, 2018, the Company entered into an amended senior secured credit facility (the “2018 Facility”), which replaced its senior secured credit facility dated June 30, 2016 (the “2016 Facility”). The 2018 Facility includes a term loan facility in an aggregate principal amount of $100 million and a revolving credit facility up to an aggregate principal amount of $150 million. The Company used the proceeds from the 2018 Facility to refinance $133.8 million of indebtedness under the 2016 Facility and to pay a dividend of $92.7 million to its stockholders. Borrowings under the facility bear interest, payable quarterly, at the Company’s option, at the base rate plus a margin (0.75% to 1.75%, dependent on the Company’s reported leverage ratio) or LIBOR plus a margin (1.75% to 2.75%, dependent on the Company’s reported leverage ratio). The 2018 Facility matures in January 2023.

As of March 31, 2018, the term loan facility and the revolving credit facility had outstanding balances of $98.8 million and $124.6 million, respectively, bearing interest at 3.63%.

During the thirteen weeks endedMarch 31, 2018, the Company made payments of $4.5 million and $1.3 million on the outstanding principal balance of its revolving credit facility and term loan facility, respectively, under the 2018 Facility.

In conjunction with the 2018 Facility, the Company evaluated the refinancing of the 2016 Facility and determined $202.5 million should be accounted for as a debt modification and $47.5 million should be new debt issuance. The Company incurred $1.0 million in financing costs of which $0.2 million was expensed and $0.8 million was capitalized and is being amortized using the effective interest rate method.

The 2018 Facility is secured by substantially all assets of the Company and requires compliance with certain financial and non-financial covenants. As of March 31, 2018, the Company was in compliance with all covenants.

As of March 31, 2018, the scheduled principal payments on debt were as follows (in thousands):

Remainder of fiscal year 2018	$	3,750
Fiscal year 2019	3,750
Fiscal year 2020	5,000
Fiscal year 2021	5,000
Fiscal year 2022	6,250
Fiscal year 2023	199,608
Total	$	223,358

(7)    Commitments and Contingencies

WRI leases certain office and retail space and equipment under non-cancelable operating leases with terms expiring at various dates through February 2032.

A schedule of future minimum rental payments required under our operating leases, excluding contingent rent, that have initial or remaining non-cancelable lease terms in excess of one year, as of March 31, 2018, is as follows (in thousands):

Remainder of fiscal year 2018	$	1,370
Fiscal year 2019	1,632
Fiscal year 2020	1,507
Fiscal year 2021	1,353
Fiscal year 2022	1,297
Fiscal year 2023	1,105
Thereafter	3,331
Total	$	11,595

Rent expense under cancelable and non-cancelable leases was $533,000 and $491,000 for the thirteen weeks endedMarch 31, 2018 and April 1, 2017, respectively.

The Company is subject to legal proceedings, claims and liabilities, such as employment-related claims and premises-liability cases, which arise in the ordinary course of business and are generally covered by insurance. In the opinion of management, the

(Unaudited)

amount of ultimate liability with respect to those actions should not have a material adverse impact on the Company’s financial position, results of operations or cash flows.

(8)Stock-Based Compensation

Stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as expense over the requisite employee service period (generally the vesting period of the grant). The Company recognized $0.5 million in stock compensation expense for the thirteen weeks endedMarch 31, 2018, with a corresponding increase to additional paid-in-capital. Stock compensation expense is included in SG&A in the Consolidated Statements of Operations.

Stock Options

The following table summarizes stock option activity (in thousands, except per share data):

	Stock Options		Weighted Average Exercise Price		Aggregate Intrinsic Value		Weighted Average Remaining Term
Outstanding - December 30, 2017	420		$	5.45	$	14,068	5.7
Options granted	2		$	44.03
Options exercised	(25	)	$	6.51
Options canceled	(19	)	$	5.04
Outstanding - March 31, 2018	378		$	5.02	$	15,956	5.3

The total grant-date fair value of stock options vested during the thirteen weeks endedMarch 31, 2018 was $0.4 million. The total intrinsic value of stock options exercised during the thirteen weeks endedMarch 31, 2018 was $1.0 million. As of March 31, 2018, total unrecognized compensation expense related to unvested stock options was $0.7 million, which is expected to be recognized over a weighted-average period of 1.7 years.

Restricted Stock Units and Performance Stock Units

The following table summarizes activity related to restricted stock units and performance stock units (in thousands, except per share data):

	Restricted Stock Units		Weighted Average Grant Date Fair Value		Performance Stock Units		Weighted Average Grant Date Fair Value
Outstanding - December 30, 2017	94		$	27.11	86		$	27.63
Units granted	56		44.03		51		44.03
Units vested	(28	)	26.74		(14	)	26.25
Units canceled	(9	)	26.30		(7	)	26.30
Outstanding - March 31, 2018	113		$	35.73	116		$	38.08

The fair value of restricted stock units and performance stock units is based on the closing market price of the stock on the date of grant. The restricted stock units granted during the thirteen weeks endedMarch 31, 2018 vest over a three year service period. As of March 31, 2018, total unrecognized compensation expense related to unvested restricted stock units was $3.8 million, which is expected to be recognized over a weighted-average period of 2.4 years.

The performance stock units vest based on the outcome of certain performance criteria. For performance stock units granted during the thirteen weeks endedMarch 31, 2018, the amount of units that can be earned range from 0% to 100% of the number of performance awards granted, based on the achievement of certain adjusted EBITDA targets, as defined by the applicable award agreement, over a performance period of one to three years. The compensation expense related to the performance stock units is recognized over the vesting period when the achievement of the performance conditions become probable. During the thirteen weeks endedMarch 31, 2018, there was a modification to certain awards resulting in additional compensation expense of $0.9 million over the remaining term of the awards.

As of March 31, 2018, total unrecognized compensation expense related to unvested performance stock units was $4.2 million, which is expected to be recognized over a weighted-average period of 2.3 years.

Restricted Stock Awards

The fair value of the non-vested restricted stock awards is based on the closing price on the date of grant. As of March 31, 2018, total unrecognized compensation expense related to unvested restricted stock awards was $0.3 million, which will be recognized over a weighted average period of approximately 1.9 years.

(9)Business Segments

Our business operates in two segments: the “Franchise” segment and the “Company” segment. The Franchise segment consists of domestic and international franchise restaurants, which represent the majority of our system-wide restaurants. As of March 31, 2018, the franchise operations segment consisted of 1,133 restaurants operated by Wingstop franchisees in the United States and eight countries outside of the United States as compared to 1,010 franchised restaurants in operation as of April 1, 2017. Franchise operations revenue consists primarily of franchise royalty revenue, advertising fee revenue, franchise and development fees revenue, international territory fees, and other revenue.

As of March 31, 2018, the Company segment consisted of 24 company-owned restaurants, located in the United States, as compared to 21 company-owned restaurants as of April 1, 2017. Company restaurant sales are comprised of food and beverage sales at company-owned restaurants. Company restaurant expenses are operating expenses at company-owned restaurants and include food, beverage, labor, benefits, utilities, rent and other operating costs.

Information on segments and a reconciliation to income before taxes are as follows (in thousands):

	Thirteen Weeks Ended

(10)    Restaurant Acquisition

On February 19, 2018, the Company acquired one existing restaurant from a franchisee. The total purchase price was $1.9 million, which was funded by cash flows from operations. The results of the operations of this location are included in our Consolidated Statements of Operations as of the date of acquisition. The acquisition was accounted for as a business combination.

14

WINGSTOP INC. AND SUBSIDIARIES

(Unaudited)

The following table summarizes the preliminary allocation of the purchase price to the estimated fair values of assets acquired and liabilities assumed at the date of the acquisition (in thousands): 

	Purchase Price Allocation
Inventory	$	4
Property and equipment	26
Reacquired franchise rights	541
Goodwill	1,331
Gift card liability	(2		)
Total purchase price	$	1,900

The estimates of fair value are preliminary, and are therefore subject to further refinement. The excess of the purchase price over the aggregate fair value of assets acquired was allocated to goodwill and is attributable to the benefits expected as a result of the acquisition, including sales and unit growth opportunities. As of March 31, 2018, $1.3 million of the goodwill from the acquisition is expected to be deductible for federal income tax purposes.

Pro-forma financial information of the combined entities is not presented due to the immaterial impact of the financial results of the acquired restaurant on our consolidated financial statements.

The fair value measurement of tangible and intangible assets and liabilities as of the acquisition date is based on significant inputs not observed in the market and thus represents a Level 3 fair value measurement. Fair value measurements for reacquired franchise rights were determined using the income approach. Fair value measurements for property and equipment were determined using the cost approach.

(11)    Revenue from Contracts with Customers

Revenue from contracts with customers consist primarily of royalties, advertising fund contributions, initial and renewal franchise fees and upfront fees from development agreements and international territory agreements. Our performance obligations under franchise agreements consist of (a) a franchise license, (b) pre-opening services, such as training, and (c) ongoing services, such as management of the Ad Fund, development of training materials and menu items and restaurant monitoring. These performance obligations are highly interrelated so we do not consider them to be individually distinct and therefore account for them under ASC 606 as a single performance obligation, which is satisfied by providing a right to use our intellectual property over the term of each franchise agreement.

Royalties, including franchisee contributions to advertising fund, are calculated as a percentage of franchise restaurant sales over the term of the franchise agreement. Initial and renewal franchise fees are payable by the franchisee prior to the restaurant opening or at the time of a renewal of an existing franchise agreement. Our franchise agreement royalties, inclusive of advertising fund contributions, represent sales-based royalties that are related entirely to our performance obligation under the franchise agreement and are recognized as franchise sales occur. Additionally, under ASC 606, initial and renewal franchise fees are recognized as revenue on a straight-line basis over the term of the respective agreement. Our performance obligation under development agreements and international territory agreements generally consists of an obligation to grant exclusive development rights over a stated term. These development rights are not distinct from franchise agreements, so upfront fees paid by franchisees for development rights are deferred and apportioned to each franchise restaurant opened by the franchisee. The pro rata amount apportioned to each restaurant is accounted for as an initial franchise fee.

The following table represents a disaggregation of revenue from contracts with customers for the thirteen weeks endedMarch 31, 2018 and April 1, 2017 (in thousands):

	Thirteen Weeks Ended
	March 31, 2018		April 1, 2017
			As adjusted*
Royalty revenue	$	15,386	$	12,691
Advertising fees and related income	8,605		7,268
Franchise fees	685		741

WINGSTOP INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(Unaudited)

Franchise fee, development fee, and international territory fee payments received by the Company are recorded as deferred revenue on the Consolidated Balance Sheet, which represents a contract liability. Deferred revenue is reduced as fees are recognized in revenue over the term of the franchise license for the respective restaurant. Approximately $10.2 million and $10.1 million of deferred revenue as of March 31, 2018 and December 30, 2017, respectively, relates to restaurants that have not yet opened, so the fees are not yet being amortized. The weighted average remaining amortization period for deferred franchise and renewal fees related to open restaurants is 7.8 years. The Company does not have any material contract assets as of March 31, 2018.

(12)    Subsequent Events

Restaurant Acquisitions

On April 16, 2018, the Company acquired one existing restaurant from a franchisee. The total purchase price was $1.9 million and was funded by cash flows from operations.

On May 1, 2018, the Company acquired one existing restaurant from a franchisee. The total purchase price was $2.2 million and was funded by cash flows from operations.

The restaurant acquisitions noted above will be accounted for as business combinations. The Company is still determining the estimated fair value of assets acquired and liabilities assumed. The excess of the purchase price over the aggregate fair value of assets acquired will be allocated to goodwill. The results of operations of these locations will be included in our Consolidated Statements of Operations as of the respective dates of acquisition.

Item 2.     Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying unaudited consolidated financial statements and related notes in Item 1 and with the audited consolidated financial statements and the related notes included in our annual report on Form 10-K. The statements in this discussion regarding industry outlook, our expectations regarding our future performance, liquidity and capital resources and other non-historical statements in this discussion are forward-looking statements. These forward-looking statements are subject to risks and uncertainties, including, but not limited to, the risks and uncertainties described in “Special Note Regarding Forward-Looking Statements” below and “Risk Factors” on page 15 of our annual report on Form 10-K. Our actual results may differ materially from those contained in or implied by any forward-looking statements.

We operate on a 52 or 53 week fiscal year ending on the last Saturday of each calendar year. Our fiscal quarters are comprised of 13 weeks, with the exception of the fourth quarter of a 53 week year, which contains 14 weeks. Fiscal years 2018 and 2017 each contain 52 weeks.

Amounts presented in Item 2 for the thirteen weeks endedApril 1, 2017 have been retrospectively adjusted to reflect the adoption of ASU 2014-09. See footnote 1 in the notes to the consolidated financial statements.

Overview

Wingstop is a high-growth franchisor and operator of restaurants that offer cooked-to-order, hand-sauced and tossed chicken wings.

We believe we pioneered the concept of wings as a “center-of-the-plate” item for all of our meal occasions. While other concepts include wings as add-on menu items or focus on wings in a bar or sports-centric setting, we are singularly focused on wings, fries and sides, which generate approximately 92% of our system-wide sales.

We offer 11 bold, distinctive and craveable flavors on our bone-in and boneless chicken wings paired with hand-cut, seasoned fries and sides made fresh daily. Our menu is highly-customizable for different dining occasions, and we believe it delivers a compelling value proposition for groups, families, and individuals. We have broad and growing consumer appeal anchored by a sought after core demographic of 18-34 year old Millennials, which we believe is a loyal consumer group that dines at fast casual restaurants more frequently.

Wingstop is the largest fast casual chicken wings-focused restaurant chain in the world and has demonstrated strong, consistent growth. As of March 31, 2018, we had a total 1,157 restaurants across 42 states and nine countries in our system. Our restaurant base is 98% franchised, with 1,133 franchised locations (including 112 international locations) and 24 company-owned restaurants.

Key Performance Indicators

Key measures that we use in evaluating our restaurants and assessing our business include the following:

Number of restaurants. Management reviews the number of new restaurants, the number of closed restaurants, and the number of acquisitions and divestitures of restaurants to assess net new restaurant growth.

	Thirteen Weeks Ended
	March 31, 2018		April 1, 2017
Domestic Franchised Activity:
Beginning of period	1,004		901
Openings	22		28
Closures	(4	)	(2	)
Acquired by Company	(1	)	—
Restaurants end of period	1,021		927
Domestic Company-Owned Activity:
Beginning of period	23		21

Total Domestic Restaurants	1,045		948
International Franchised Activity:
Beginning of period	106		76
Openings	6		7
Closures	—		—
Restaurants end of period	112		83
Total System-wide Restaurants	1,157		1,031

System-wide sales. System-wide sales represents net sales for all of our company-owned and franchised restaurants, as reported by franchisees. While we do not record franchised restaurant sales as revenue, our royalty revenue is calculated based on a percentage of franchised restaurant sales, which generally range from 5.0% to 6.0% of gross sales net of discounts. This measure allows management to better assess changes in our royalty revenue, our overall store performance, the health of our brand and the strength of our market position relative to competitors. Our system-wide sales growth is driven by new restaurant openings as well as increases in same store sales.

Average unit volume (AUV). AUV consists of the average annual sales of all restaurants that have been open for a trailing 52-week period or longer. This measure is calculated by dividing sales during the applicable period for all restaurants being measured by the number of restaurants being measured. Domestic AUV includes revenue from both company-owned and franchised restaurants. AUV allows management to assess our company-owned and franchised restaurant economics. Changes in AUV are primarily driven by increases in same store sales and are also influenced by opening new restaurants.

Same store sales. Same store sales reflects the change in year-over-year sales for the same store base. We define the same store base to include those restaurants open for at least 52 full weeks. This measure highlights theperformance of existing restaurants, while excluding the impact of new restaurant openings and closures. We reviewsame store sales for company-owned restaurants as well as system-wide restaurants. Same store sales aredriven by changes in transactions and average transaction size. Transaction size changes are driven by price changes or product mix shifts from either a change in the number of items purchased or shifts into higher/lower priced categories of items.

18

EBITDA and Adjusted EBITDA. We define EBITDA as net income before interest expense, net, income tax expense, and depreciation and amortization. Adjusted EBITDA represents EBITDA with further adjustments for transaction costs, gains and losses on the disposal of assets, and stock-based compensation expense. EBITDA and Adjusted EBITDA may not be comparable to other similarly titled captions of other companies due to differences in methods of calculation. For a reconciliation of net income to EBITDA and Adjusted EBITDA see the table below. For further discussion of EBITDA and Adjusted EBITDA as non-GAAP measures and how we utilize them see footnote 2 below.

The following table sets forth our key performance indicators as well as our total revenue and net income for the thirteen weeks endedMarch 31, 2018 and April 1, 2017 (dollars in thousands):

	Thirteen Weeks Ended
	March 31, 2018			April 1, 2017
Number of system-wide restaurants open at end of period	1,157			1,031
System-wide sales (1)	$	312,981		$	259,925
Domestic restaurant AUV	$	1,120		$	1,101
System-wide domestic same store sales growth	9.5		%	(1.1		)%
Company-owned domestic same store sales growth	12.5		%	(5.1		)%
Total revenue	$	37,389		$	33,410
Net income	$	6,168		$	6,257
Adjusted EBITDA (2)	$	12,492		$	9,535

(1) The percentage of system-wide sales attributable to company-owned restaurants was 3.5% and 3.3% for the thirteen weeks endedMarch 31, 2018 and April 1, 2017, respectively. The remainder was generated by franchised restaurants, as reported by our franchisees.

(2) EBITDA and Adjusted EBITDA are supplemental measures of our performance that are not required by, or presented in accordance with, U.S. GAAP. EBITDA and Adjusted EBITDA are not measurements of our financial performance under U.S. GAAP and should not be considered as an alternative to net income or any other performance measure derived in accordance with U.S. GAAP, or as an alternative to cash flows from operating activities as a measure of our liquidity.

We define “EBITDA” as net income before interest expense, net, income tax expense, and depreciation and amortization. We define “Adjusted EBITDA” as EBITDA further adjusted for transaction costs, gains and losses on the disposal of assets and stock-based compensation expense. There were no gains and losses on disposal of assets during the thirteen weeks endedMarch 31, 2018 and April 1, 2017. We caution investors that amounts presented in accordance with our definitions of EBITDA and Adjusted EBITDA may not be comparable to similar measures disclosed by our competitors, because not all companies and analysts calculate EBITDA and Adjusted EBITDA in the same manner. We present EBITDA and Adjusted EBITDA because we consider them to be important supplemental measures of our performance and believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. Management believes that investors’ understanding of our performance is enhanced by including these non-GAAP financial measures as a reasonable basis for comparing our ongoing results of operations. Many investors are interested in understanding the performance of our business by comparing our results from ongoing operations on a period-over-period basis and would ordinarily add back non-cash expenses such as depreciation and amortization, as well as items that are not part of normal day-to-day operations of our business.

Management uses EBITDA and Adjusted EBITDA:

• as a measurement of operating performance because they assist us in comparing the operating performance of our restaurants on a consistent basis, as they remove the impact of items not directly resulting from our core operations;

• for planning purposes, including the preparation of our internal annual operating budget and financial projections;

• to evaluate the performance and effectiveness of our operational strategies;

• to evaluate our capacity to fund capital expenditures and expand our business; and

• to calculate incentive compensation payments for our employees, including assessing performance under our annual incentive compensation plan and determining the vesting of performance-based equity awards.

19

By providing these non-GAAP financial measures, together with a reconciliation to the most comparable GAAP measure, we believe we are enhancing investors’ understanding of our business and our results of operations, as well as assisting investors in evaluating how well we are executing our strategic initiatives. In addition, the instruments governing our indebtedness use EBITDA (with additional adjustments) to measure our compliance with covenants such as our fixed charge coverage, lease adjusted leverage and debt incurrence. EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation, or as an alternative to, or a substitute for net income or other financial statement data presented in our consolidated financial statements as indicators of financial performance. Some of the limitations are:

• such measures do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;

• such measures do not reflect changes in, or cash requirements for, our working capital needs;

• such measures do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments on our debt;

• such measures do not reflect our tax expense or the cash requirements to pay our taxes;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and such measures do not reflect any cash requirements for such replacements; and

• other companies in our industry may calculate such measures differently than we do, limiting their usefulness as comparative measures.

Due to these limitations, EBITDA and Adjusted EBITDA should not be considered as measures of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our U.S. GAAP results and using these non-GAAP measures only supplementally. As noted in the table below, Adjusted EBITDA includes adjustments for transaction costs, gains and losses on disposal of assets and stock-based compensation, among other items. It is reasonable to expect that these items will occur in future periods. However, we believe these adjustments are appropriate because the amounts recognized can vary significantly from period to period, do not directly relate to the ongoing operations of our restaurants and complicate comparisons of our internal operating results and operating results of other restaurant companies over time. Each of the normal recurring adjustments and other adjustments described in this paragraph and in the reconciliation table below help management measure our core operating performance over time by removing items that are not related to day-to-day operations.

The following table reconciles net income to EBITDA and Adjusted EBITDA for the thirteen weeks endedMarch 31, 2018 and April 1, 2017 (in thousands):

	Thirteen Weeks Ended
	March 31, 2018		April 1, 2017
Net income	$	6,168	$	6,257
Interest expense, net	1,736		1,299
Income tax expense	1,662		969
Depreciation and amortization	950		755
EBITDA	$	10,516	$	9,280
Additional adjustments:
Transaction costs (a)	1,462		—
Stock-based compensation expense (b)	514		255
Adjusted EBITDA	$	12,492	$	9,535

(a) Represents costs and expenses related to the refinancing of the 2016 Facility and payment of a special dividend; all transaction costs are included in SG&A.

(b) Includes non-cash, stock-based compensation.

⁽¹⁾ Cost of sales excludes depreciation and amortization, which are presented separately, and includes advertising expenses incurred at company-owned restaurants.

Total revenue. During the thirteen weeks endedMarch 31, 2018, total revenue was $37.4 million, an increase of $4.0 million, or 11.9%, compared to $33.4 million in the comparable period in 2017.

Royalty revenue, franchise fees and other. During the thirteen weeks endedMarch 31, 2018, royalty revenue, franchise fees and other were $17.8 million, an increase of $0.2 million, or 1.1%, compared to $17.6 million in the comparable period in 2017. Royalty revenue increased$2.7 million due to 123 net franchise restaurant openings since April 1, 2017and domestic same store sales growth of 9.5%. This increase was partially offset by a decrease in other revenue of$2.5 million, primarily due to a one-time payment received in conjunction with a vendor agreement executed during the thirteen weeks endedApril 1, 2017.

Advertising fees and related income. During the thirteen weeks endedMarch 31, 2018, advertising fees and related income were $8.6 million, an increase of $1.3 million, or 18.4%, compared to $7.3 million in the comparable period in 2017. Advertising fees increased primarily due to the increase in system-wide sales in the thirteen weeks endedApril 1, 2017 versus the thirteen weeks endedMarch 31, 2018.

Company-owned restaurant sales. During the thirteen weeks endedMarch 31, 2018, company-owned restaurant sales were $11.0 million, an increase of $2.5 million, or 28.8%, compared to $8.5 million in the comparable period in 2017. The increase is the result of $1.3 million in combined sales in the current fiscal first quarter related to the acquisition of two restaurants from a franchisee in the third quarter 2017 and the acquisition of one restaurant from a franchisee in the first quarter of 2018, and company-owned domestic same store sales growth of 12.5%, which was driven equally by an increase in transactions and an increase in average transaction size.

Cost of sales. During the thirteen weeks endedMarch 31, 2018, cost of sales was $7.4 million, an increase of $0.8 million, or 12.1%, compared to $6.6 million in the comparable period in 2017. Cost of sales as a percentage of company-owned restaurant sales was 67.2% in the quarter ended March 31, 2018 compared to 77.2% in the prior year.

21

The table below presents the major components of cost of sales (dollars in thousands):

	Thirteen Weeks Ended
	March 31, 2018			As a % of company-owned restaurant sales		April 1, 2017			As a % of company-owned restaurant sales
Cost of sales:
Food, beverage and packaging costs	$	3,684		33.5	%	$	3,354		39.2	%
Labor costs	2,385			21.7	%	2,116			24.8	%
Other restaurant operating expenses	1,606			14.6	%	1,338			15.7	%
Vendor rebates	(278		)	(2.5	)%	(208		)	(2.4	)%
Total cost of sales	$	7,397		67.2	%	$	6,600		77.2	%

Food, beverage and packaging costs as a percentage of company-owned restaurant sales were 33.5% in the thirteen weeks endedMarch 31, 2018 compared to 39.2% in the comparable period in 2017. The decrease was primarily due to an 11.3%decrease in the cost of bone-in chicken wings as compared to the prior year period.

Labor costs as a percentage of company-owned restaurant sales were 21.7% for the thirteen weeks endedMarch 31, 2018, compared to 24.8% in the comparable period in 2017. The decrease as a percentage of company-owned restaurant sales was primarily due to our ability to leverage costs due to the company-owned domestic same store sales increase of 12.5%.

Other restaurant operating expenses as a percentage of company-owned restaurant sales were 14.6% for the thirteen weeks endedMarch 31, 2018 compared to 15.7% in the comparable period in 2017. The decrease as a percentage of company-owned restaurant sales was primarily due to our ability to leverage costs due to the company-owned domestic same store sales increase of 12.5%.

Advertising expenses. During the thirteen weeks endedMarch 31, 2018, advertising expenses were $8.6 million, a decrease of $0.6 million, compared to $9.3 million in the comparable period in 2017. Under the new accounting guidance, advertising expenses are recognized at the same time the related revenue is recognized, which does not necessarily correlate to actual timing of the advertising spend. In the prior year period, we received a one-time payment from a vendor, which was primarily used to fund our launch of national advertising, and resulted in a corresponding increase in advertising expense by approximately $1.9 million for the thirteen weeks endedApril 1, 2017.

Selling, general and administrative. During the thirteen weeks endedMarch 31, 2018, SG&A expense was $10.8 million, an increase of $2.6 million compared to $8.2 million in the comparable period in 2017. The increase in SG&A expense was primarily due to nonrecurring costs of $1.5 million related to the refinancing of the 2016 Facility (as defined herein) and subsequent special dividend payout, which occurred in the first quarter of 2018. The remaining increase was primarily due to an increase in payroll and benefit expenses related to planned headcount additions, as compared to the prior year period.

Depreciation and amortization. During the thirteen weeks endedMarch 31, 2018, depreciation expense was $1.0 million, an increase of $0.2 million, compared to $0.8 million in the comparable period in 2017. The increase in depreciation was primarily due to the capital expenditures as a result of the acquisition of more company-owned restaurants.

Interest expense, net. During the thirteen weeks endedMarch 31, 2018, interest expense was $1.7 million, an increase of $0.4 million compared to $1.3 million in the comparable period in 2017. The increase was primarily due to an increase in the principal amount of indebtedness and applicable interest rate related to the refinancing of the 2016 Facility in January 2018.

Income tax expense. Income tax expense was $1.7 million in the thirteen weeks endedMarch 31, 2018, yielding an effective tax rate of 21.2%, compared to an effective tax rate of 13.4% in the prior year. The increase in the effective tax rate was due to $0.4 million in tax benefits resulting from the recognition of excess tax benefits from stock-based compensation in income tax expense compared to $1.7 million of excess tax benefits in the prior year period. The benefit was partially affected by the reduction in the federal statutory rate for thirteen weeks endedMarch 31, 2018 from 35% to 21% effective the first day of fiscal 2018.

22

Segment results. The following table sets forth our revenue and operating profit for each of our segments for the period presented (dollars in thousands):

	Thirteen Weeks Ended				Increase / (Decrease)
	March 31, 2018		April 1, 2017		$		%
Revenue:
Franchise segment	$	26,386	$	24,864	$	1,522	6.1	%
Company segment	11,003		8,546		2,457		28.8	%
Total segment revenue	$	37,389	$	33,410	$	3,979	11.9	%
Segment Profit:
Franchise segment	$	8,387	$	7,446	$	941	12.6	%
Company segment	2,641		1,079		1,562		144.8	%
Total segment profit	$	11,028	$	8,525	$	2,503	29.4	%

Franchise segment. During the thirteen weeks endedMarch 31, 2018, franchise segment revenue was $26.4 million, an increase of $1.5 million, or 6.1%, compared to $24.9 million in the comparable period in 2017. Royalty revenue increased$2.7 million due to 123 net franchise restaurant openings since April 1, 2017 and domestic same store sales growth of 9.5%. Other revenuedecreased$2.5 million,primarily due to a decrease in vendor rebates related to a one-time payment received in conjunction with a vendor agreement executed during the thirteen weeks ended April 1, 2017. Advertising fees and related income increased $1.3 million due to the increase in system-wide sales from April 1, 2017 to March 31, 2018

During the thirteen weeks endedMarch 31, 2018, franchise segment profit was $8.4 million, an increase of $0.9 million, or 12.6%, compared to $7.4 million in the comparable period in 2017 primarily due to the growth in franchise segment revenue.

Company segment. During the thirteen weeks endedMarch 31, 2018, company-owned restaurant sales were $11.0 million, an increase of $2.5 million, or 28.8%, compared to $8.5 million in the comparable period in 2017. The increase was the result of $1.3 million in combined sales related to the acquisition of two restaurants from a franchisee in the third quarter 2017 and the acquisition of one restaurant from a franchisee in the first quarter of 2018, and company-owned domestic same store sales growth of 12.5%.

During the thirteen weeks endedMarch 31, 2018, company segment profit was $2.6 million, an increase of $1.6 million, compared to $1.1 million in the comparable period in 2017. The increase was primarily due to an 11.3%decrease in the commodities rates for bone-in chicken wings, as well as the leveraging of fixed costs due to the company-owned same store sales growth of 12.5%.

Liquidity and Capital Resources

General. Our primary sources of liquidity and capital resources are cash provided from operating activities, cash and cash equivalents on hand, and proceeds from the incurrence of debt. Our primary requirements for liquidity and capital are working capital and general corporate needs. Historically, we have operated with minimal positive working capital or negative working capital. We believe that our sources of liquidity and capital will be sufficient to finance our continued operations and growth strategy.

The following table shows summary cash flows information for the thirteen weeks endedMarch 31, 2018 and April 1, 2017 (in thousands):

	Thirteen Weeks Ended
	March 31, 2018			April 1, 2017
Net cash provided by (used in):
Operating activities	$	9,456		$	7,364
Investing activities	(2,326		)	(419		)
Financing activities	(5,947		)	(5,293		)
Net change in cash and cash equivalents	$	1,183		$	1,652

Operating activities. Our cash flows from operating activities are principally driven by sales at both franchise restaurants and company-owned restaurants, as well as franchise and development fees. We collect franchise royalties from our franchise owners on a weekly basis. Restaurant-level operating costs at our company-owned restaurants, unearned franchise and development fees and corporate overhead costs also impact our cash flows from operating activities.

Net cash provided by operating activities was $9.5 million in the thirteen weeks endedMarch 31, 2018, an increase of $2.1 million from $7.4 million in 2017. The increase was primarily due to the timing of changes in working capital.

Investing activities. Our net cash used in investing activities was $2.3 million in the thirteen weeks endedMarch 31, 2018, an increase of $1.9 million from $0.4 millionused in investing activities in 2017. The increase was due to the acquisition of one restaurant from a franchisee during the first quarter 2018.

Financing activities. Our net cash used in financing activities was $5.9 million in the thirteen weeks endedMarch 31, 2018, an increase of $0.7 million from cash used in financing activities of $5.3 million in 2017. The increase was due to the payment of both a quarterly dividend and a special dividend totaling $94.8 million, as well as payment of deferred financing costs of $0.8 million related to the refinancing of the 2016 Facility in the current period. This was partially offset by net borrowings of long-term debt of $89.6 million during the thirteen weeks endedMarch 31, 2018, compared to net repayments of $5.9 million in the comparable period in 2017.

Senior secured credit facility. On January 30, 2018, we entered into an amended $250.0 million senior secured credit facility (the “2018 Facility”), which replaced the senior secured credit facility dated June 30, 2016 (the “2016 Facility”). The 2018 Facility consists of a term loan facility in the aggregate amount of $100.0 million and a revolving credit facility up to an aggregate amount of $150.0 million. The 2018 Facility has a five year term and matures on January 30, 2023.

We utilized approximately $230 million of proceeds from the 2018 Facility to refinance $133.8 million of indebtedness under the 2016 Facility and to pay a special cash dividend of $92.7 million to our stockholders. The 2018 Facility bears interest, at our option, at either the prime rate plus an applicable margin ranging from 0.75% to 1.75% or at an adjusted LIBOR rate plus an applicable margin ranging from 1.75% to 2.75%, in each case based on our lease adjusted leverage ratio.

The 2018 Facility is secured by a first-priority security interest in substantially all of our assets. Obligations under the 2018 Facility are guaranteed by the Company and its subsidiaries. The 2018 Facility also requires compliance with certain financial and non-financial covenants, including a specified lease adjusted leverage ratio and a specified fixed charge coverage ratio. Failure to comply with these covenants in the future could cause an acceleration of outstanding amounts under the term loan and revolver and restrict us from borrowing under the revolving credit facility to fund our liquidity requirements.

As of March 31, 2018, the term loan facility and the revolving credit facility had outstanding balances of $98.8 million and $124.6 million, respectively, bearing interest at 3.63%.

24

Dividends. In August 2017, we announced that our board of directors authorized a regular dividend program under which we intend to pay quarterly dividends on our common stock, subject to quarterly declarations by our Board of Directors. A dividend of $0.07 was announced during the first quarter of 2018, which was paid on March 23, 2018. Subsequent to the first quarter, the Company’s Board of Directors approved a dividend of $0.07, to be paid on June 18, 2018.

In addition, we paid a special cash dividend of $3.17 per share on February 14, 2018 in connection with the 2018 Facility.

We do not currently expect the restrictions in the 2018 Facility to impact our ability to make regularly quarterly dividends pursuant to our quarterly dividend program. However, any future declarations of dividends, as well as the amount and timing of such dividends, is subject to capital availability and the discretion of our board of directors, which must evaluate, among other things, whether cash dividends are in the best interest of our stockholders.

Contractual Obligations

In connection with the 2018 Facility, principal payments of $1,250,000 are due quarterly with all unpaid amounts due at maturity in January 2023.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements or obligations, except for leases, as of March 31, 2018.

Critical Accounting Policies and Estimates

Our consolidated financial statements and accompanying notes are prepared in accordance with GAAP. Preparing consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. These estimates and assumptions are affected by the application of our accounting policies. Critical accounting estimates are those that require application of management’s most difficult, subjective or complex judgments, often as a result of matters that are inherently uncertain and may change in subsequent periods. While we apply our judgment based on assumptions believed to be reasonable under the circumstances, actual results could vary from these assumptions. It is possible that materially different amounts would be reported using different assumptions. Our critical accounting policies and estimates are identified and described in our annual consolidated financial statements and the related notes included in our Form 10-K, and there have been no material changes since the filing of our annual report on Form 10-K.

Recent Accounting Pronouncements

See Note 1. “Basis of Presentation” to our consolidated financial statements included in this Quarterly Report on Form 10-Q for a summary of recent accounting pronouncements.

Special Note Regarding Forward-Looking Statements

This document contains statements about future events and expectations that constitute forward-looking statements. Forward-looking statements are based on our beliefs, assumptions and expectations of our future financial and operating performance and growth plans, taking into account the information currently available to us. Such statements include, in particular, statements about our plans, strategies and prospects. Words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “estimate,” “could,” “would,” “will” and variations of such words and similar expressions are intended to identify such forward-looking statements. Examples of forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to, our expectations with respect to our future liquidity, expenses and consumer appeal. These statements are based on beliefs and assumptions of Wingstop’s management, which in turn are based on currently available information. These statements are not guarantees of future performance and involve assumptions and risks and uncertainties that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed, implied or forecasted in such forward-looking statements.

Factors that could cause actual results or outcomes to differ from the results expressed or implied by forward-looking statements include, among other things:

• our ability to effectively implement our growth strategy;

• risks associated with changes in food and supply costs;

• our relationships with our franchisees, as well as actions by franchisees that could harm our business;

25

• our ability to identify, recruit and contract with a sufficient number of qualified franchisees;

• our ability to effectively compete within our industry;

• our ability to successfully expand into new markets;

• risks associated with food safety, food-borne illness and other health concerns;

• risks associated with interruptions in our supply chain;

• our ability to implement our domestic and international growth strategies;

• risks associated with the use and implementation of information technology;

• risks associated with litigation against us or our franchisees;

• our ability to comply with government regulations relating to food products and franchising, including increased costs associated with new or changing regulations;

• risks associated with the geographic concentration of our business;

• our ability to maintain adequate insurance coverage for our business;

• our ability to successfully advertise and market our business;

• risks associated with changes in customer preferences and perceptions;

• our ability to protect our intellectual property, including trademarks and trade secrets; and

• our ability to comply with the covenants and restrictions in the 2018 Facility.

The above list of factors is not exhaustive. Some of these and other factors are discussed in more detail under “Risk Factors” in our annual report on Form 10-K. We assume no obligation to update or revise any forward-looking statements for any reason, or to update the reasons actual results could differ materially from those anticipated in any forward-looking statements, even if new information becomes available in the future.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

Impact of Inflation.The primary inflationary factors affecting our and our franchisees’ operations are food and beverage costs, labor costs, energy costs and the costs and materials used in the construction of new restaurants. Our restaurant operations are subject to federal and state minimum wage laws governing such matters as working conditions, overtime and tip credits. Significant numbers of our and our franchisees’ restaurant personnel are paid at rates related to the federal and/or state minimum wage and, accordingly, increases in the minimum wage increase our and our franchisees’ labor costs. To the extent permitted by competition and the economy, we have mitigated increased costs by increasing menu prices and may continue to do so if deemed necessary in future years. Substantial increases in costs and expenses could impact our operating results to the extent such increases cannot be passed through to our customers. Historically, inflation has not had a material effect on our results of operations. Severe increases in inflation, however, could affect the global and U.S. economies and could have an adverse impact on our business, financial condition and results of operations.

Commodity Price Risk. We are exposed to market risks from changes in commodity prices. Many of the food products purchased by us are affected by weather, production, availability and other factors outside our control. Although we attempt to minimize the effect of price volatility by negotiating fixed price contracts for the supply of key ingredients, there are no established fixed price markets for fresh bone-in chicken wings, so we are subject to prevailing market conditions. Bone-in chicken wings accounted for approximately 27.2% and 31.1% of our company-owned restaurant cost of sales during the thirteen weeks endedMarch 31, 2018 and April 1, 2017, respectively. A hypothetical 10% increase in the bone-in chicken wing costs would have increased costs of sales by approximately $0.2 million during the thirteen weeks endedMarch 31, 2018. We do not engage in speculative financial transactions nor do we hold or issue financial instruments for trading purposes. In instances when we use fixed pricing arrangements with our suppliers, these arrangements cover our physical commodity needs, are not net-settled, and are accounted for as normal purchases.

Interest Rate Risk. We are subject to interest rate risk in connection with borrowings under the 2018 Facility, which bears interest at variable rates. As of March 31, 2018, we had $223.4 million outstanding under the 2018 Facility. Derivative financial instruments, such as interest rate swap agreements and interest rate cap agreements, may be used for the purpose of managing fluctuating interest rate exposures that exist from our variable rate debt obligations that are expected to remain outstanding. Interest rate changes do not affect the market value of such debt, but could impact the amount of our interest payments, and accordingly, our future earnings and cash flows, assuming other factors are held constant. A hypothetical 1.0% percentage point increase or decrease in the interest rate associated with our credit facilities would have resulted in a $2.2 million impact on interest expense on an annualized basis.

27

Item 4.     Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2018, pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no significant changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

Basis of Presentation

Wingstop Inc., through its primary operating subsidiary, Wingstop Restaurants Inc. (“WRI”), collectively referred to as the “Company”, is in the business of franchising and operating Wingstop restaurants. As of March 31, 2018, 1,021 franchised restaurants were in operation domestically, and 112 international franchised restaurants were in operation across eight countries. As of March 31, 2018, the Company owned and operated 24 restaurants.

The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Consequently, financial information and disclosures normally included in financial statements prepared annually in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Balance sheet amounts are as of March 31, 2018 and December 30, 2017 and operating results are for the thirteen weeks endedMarch 31, 2018 and April 1, 2017.

In the Company’s opinion, all necessary adjustments have been made for the fair presentation of the results of the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year. The accompanying interim unaudited consolidated financial statements should be read in conjunction with the audited financial statements and the related notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 30, 2017.

The Company uses a 52/53-week fiscal year that ends on the last Saturday of the calendar year. Fiscal years 2018 and 2017 have 52 weeks.

The Company has reclassified certain prior period amounts due to the adoption of ASU 2014-09 and ASU 2016-18, as defined below.

Advertising Fund

The Company administers the Wingstop Restaurants Advertising Fund (“Ad Fund”), which is used for various forms of advertising for the Wingstop brand. Advertising fund contributions and expenditures are reported on a gross basis in the Consolidated Statements of Operations, which are largely offsetting and therefore do not significantly impact our reported net income. Advertising expenses incurred by company-owned restaurants are included within cost of sales in the Consolidated Statements of Operations. Administrative expenses of the Ad Fund, such as administrative support services and compensation expenses of employees that provide services directly to the Ad Fund, are included in selling, general and administrative expenses (“SG&A”) in the Consolidated Statements of Operations.

The advertising fund contribution collected from Wingstop restaurant franchisees and company-owned and operated restaurants is equal to 3% of gross sales. For the thirteen weeks endedMarch 31, 2018 and April 1, 2017 the Company contributed $1.0 million and $2.9 million, respectively, for the purpose of supplementing the national advertising campaign, which were included in advertising expenses in the Consolidated Statements of Operations.

The Company consolidates and reports all assets and liabilities of the advertising fund as restricted assets of the advertising fund and liabilities of the advertising fund within current assets and current liabilities, respectively, in the Consolidated Balance Sheets. The assets and liabilities of the advertising fund consist primarily of cash, receivables, accrued expenses, other liabilities and any cumulative surplus related to the Ad Fund. Under the Company’s franchise agreements, contributions to the Ad Fund are restricted to advertising, public relations, merchandising, similar activities, and administrative expenses to increase sales and further enhance the public reputation of the Wingstop brand. The aforementioned administrative expenses may also include personnel expenses and allocated costs incurred by the Company which are directly associated with administering the advertising fund, as outlined in the provisions of the franchise agreements. Total cash balances related to the Ad Fund as of March 31, 2018 and December 30, 2017 were $3.7 million and $2.3 million, respectively.

Recently Issued Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 will be effective beginning in the first quarter of 2019. Early adoption of ASU 2016-02 as of its issuance is permitted. This new guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We anticipate implementing the standard by taking advantage of the practical expedient option. The discounted minimum remaining rental payments will be the starting point for determining the right-of-use asset and lease liability. We expect that adoption of the new guidance will have a material impact on our consolidated balance sheets due to recognition of the right-of-use asset and lease liability related to our current operating leases. The process of evaluating the full impact of the new guidance on our consolidated financial statements and disclosures is ongoing, but we anticipate the initial evaluation of the impact will be completed in fiscal 2018.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). ASU 2018-05 provides guidance on accounting for the income tax effects of the Tax Cuts and Jobs Act of 2017 (the “Act”), which impacts U.S. corporate tax rates, business-related exclusions, and deductions and credits. The Act also has tax consequences for many companies that operate internationally. The guidance in ASU 2018-05 addresses situations in which the accounting for certain income tax effects of the Act is incomplete by the time financial statements are issued for the reporting period that includes the enactment date of December 22, 2017. The new guidance requires companies to report provisional amounts if a reasonable estimate of the tax impact can be determined. If a provisional amount cannot be reasonably determined, the entity should continue to apply ASC Topic 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted.

The Company will continue to analyze additional information and guidance related to the Act as supplemental legislation, regulatory guidance, or evolving technical interpretations become available. The final impacts may differ from the recorded amounts as of March 31, 2018, and we will continue to refine such amounts within the measurement period provided by Staff Accounting Bulletin No. 118. We expect to complete our analysis no later than the fourth quarter of 2018.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance. The new guidance provides a single framework in which revenue is required to be recognized to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services.

The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting each prior reporting period presented and a cumulative effect adjustment, which was recorded as of the first day of 2016. The adoption changed the timing of recognition of initial franchise fees, development fees, territory fees for our international business and renewal and transfer fees, as well as the reporting of advertising fund contributions and related expenditures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that restricted cash and cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and a retrospective transition method is required. The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting the Statement of Cash Flows for each prior period presented.

The following table presents the effect of the adoption of ASU 2014-09 on our consolidated balance sheets as of December 30, 2017 (in thousands):

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings per Share

Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the calculation of diluted earnings per share, the basic weighted average number of shares is increased by the dilutive effect of stock options and restricted stock units, determined using the treasury stock method.

Basic weighted average shares outstanding is reconciled to diluted weighted average shares outstanding as follows (in thousands):

	Thirteen Weeks Ended
	March 31, 2018	April 1, 2017
Basic weighted average shares outstanding	29,116	28,895
Dilutive shares	387	441
Diluted weighted average shares outstanding	29,503	29,336

For the thirteen weeks endedMarch 31, 2018 and April 1, 2017, respectively, approximately 57,000 and 62,000 equity awards were excluded from the dilutive earnings per share calculation because the effect would have been anti-dilutive.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. Assets and liabilities are classified using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value as follows:

Level 1 — Unadjusted quoted prices for identical instruments traded in active markets.

Level 2 — Observable market-based inputs or unobservable inputs corroborated by market data.

Level 3 — Unobservable inputs reflecting management’s estimates and assumptions.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short-term nature. Fair value of debt is determined on a non-recurring basis, which results are summarized as follows (in thousands):

	Fair Value Hierarchy	March 31, 2018				December 30, 2017
		Carrying Value (2)		Fair Value		Carrying Value (2)		Fair Value
Senior Secured Credit Facility:
Term loan facility (1)	Level 2	$	98,750	$	98,750	$	64,750	$	64,750
Revolving credit facility (1)	Level 2	$	124,608	$	124,608	$	69,000	$	69,000

⁽¹⁾ The fair value of long-term debt was estimated using available market information.

⁽²⁾ Excluding issuance costs netted on the Consolidated Balance Sheet.

The Company also measures certain non-financial assets at fair value on a non-recurring basis, primarily long-lived assets, intangible assets and goodwill, in connection with our periodic evaluations of such assets for potential impairment.

On January 30, 2018, the Company entered into an amended senior secured credit facility (the “2018 Facility”), which replaced its senior secured credit facility dated June 30, 2016 (the “2016 Facility”). The 2018 Facility includes a term loan facility in an aggregate principal amount of $100 million and a revolving credit facility up to an aggregate principal amount of $150 million. The Company used the proceeds from the 2018 Facility to refinance $133.8 million of indebtedness under the 2016 Facility and to pay a dividend of $92.7 million to its stockholders. Borrowings under the facility bear interest, payable quarterly, at the Company’s option, at the base rate plus a margin (0.75% to 1.75%, dependent on the Company’s reported leverage ratio) or LIBOR plus a margin (1.75% to 2.75%, dependent on the Company’s reported leverage ratio). The 2018 Facility matures in January 2023.

As of March 31, 2018, the term loan facility and the revolving credit facility had outstanding balances of $98.8 million and $124.6 million, respectively, bearing interest at 3.63%.

During the thirteen weeks endedMarch 31, 2018, the Company made payments of $4.5 million and $1.3 million on the outstanding principal balance of its revolving credit facility and term loan facility, respectively, under the 2018 Facility.

In conjunction with the 2018 Facility, the Company evaluated the refinancing of the 2016 Facility and determined $202.5 million should be accounted for as a debt modification and $47.5 million should be new debt issuance. The Company incurred $1.0 million in financing costs of which $0.2 million was expensed and $0.8 million was capitalized and is being amortized using the effective interest rate method.

The 2018 Facility is secured by substantially all assets of the Company and requires compliance with certain financial and non-financial covenants. As of March 31, 2018, the Company was in compliance with all covenants.

As of March 31, 2018, the scheduled principal payments on debt were as follows (in thousands):

Remainder of fiscal year 2018	$	3,750
Fiscal year 2019	3,750
Fiscal year 2020	5,000

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Stock-Based Compensation

Stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as expense over the requisite employee service period (generally the vesting period of the grant). The Company recognized $0.5 million in stock compensation expense for the thirteen weeks endedMarch 31, 2018, with a corresponding increase to additional paid-in-capital. Stock compensation expense is included in SG&A in the Consolidated Statements of Operations.

Stock Options

The following table summarizes stock option activity (in thousands, except per share data):

	Stock Options		Weighted Average Exercise Price		Aggregate Intrinsic Value		Weighted Average Remaining Term
Outstanding - December 30, 2017	420		$	5.45	$	14,068	5.7
Options granted	2		$	44.03
Options exercised	(25	)	$	6.51
Options canceled	(19	)	$	5.04
Outstanding - March 31, 2018	378		$	5.02	$	15,956	5.3

The total grant-date fair value of stock options vested during the thirteen weeks endedMarch 31, 2018 was $0.4 million. The total intrinsic value of stock options exercised during the thirteen weeks endedMarch 31, 2018 was $1.0 million. As of March 31, 2018, total unrecognized compensation expense related to unvested stock options was $0.7 million, which is expected to be recognized over a weighted-average period of 1.7 years.

Restricted Stock Units and Performance Stock Units

The following table summarizes activity related to restricted stock units and performance stock units (in thousands, except per share data):

	Restricted Stock Units		Weighted Average Grant Date Fair Value		Performance Stock Units		Weighted Average Grant Date Fair Value
Outstanding - December 30, 2017	94		$	27.11	86		$	27.63
Units granted	56		44.03		51		44.03
Units vested	(28	)	26.74		(14	)	26.25
Units canceled	(9	)	26.30		(7	)	26.30
Outstanding - March 31, 2018	113		$	35.73	116		$	38.08

The fair value of restricted stock units and performance stock units is based on the closing market price of the stock on the date of grant. The restricted stock units granted during the thirteen weeks endedMarch 31, 2018 vest over a three year service period. As of March 31, 2018, total unrecognized compensation expense related to unvested restricted stock units was $3.8 million, which is expected to be recognized over a weighted-average period of 2.4 years.

The performance stock units vest based on the outcome of certain performance criteria. For performance stock units granted during the thirteen weeks endedMarch 31, 2018, the amount of units that can be earned range from 0% to 100% of the number of performance awards granted, based on the achievement of certain adjusted EBITDA targets, as defined by the applicable award agreement, over a performance period of one to three years. The compensation expense related to the performance stock units is recognized over the vesting period when the achievement of the performance conditions become probable. During the thirteen weeks endedMarch 31, 2018, there was a modification to certain awards resulting in additional compensation expense of $0.9 million over the remaining term of the awards.

As of March 31, 2018, total unrecognized compensation expense related to unvested performance stock units was $4.2 million, which is expected to be recognized over a weighted-average period of 2.3 years.

Restricted Stock Awards

The fair value of the non-vested restricted stock awards is based on the closing price on the date of grant. As of March 31, 2018, total unrecognized compensation expense related to unvested restricted stock awards was $0.3 million, which will be recognized over a weighted average period of approximately 1.9 years.

Business Combination Disclosure [Text Block]

Restaurant Acquisition

On February 19, 2018, the Company acquired one existing restaurant from a franchisee. The total purchase price was $1.9 million, which was funded by cash flows from operations. The results of the operations of this location are included in our Consolidated Statements of Operations as of the date of acquisition. The acquisition was accounted for as a business combination.

The following table summarizes the preliminary allocation of the purchase price to the estimated fair values of assets acquired and liabilities assumed at the date of the acquisition (in thousands): 

	Purchase Price Allocation
Inventory	$	4
Property and equipment	26
Reacquired franchise rights	541
Goodwill	1,331
Gift card liability	(2		)
Total purchase price	$	1,900

The estimates of fair value are preliminary, and are therefore subject to further refinement. The excess of the purchase price over the aggregate fair value of assets acquired was allocated to goodwill and is attributable to the benefits expected as a result of the acquisition, including sales and unit growth opportunities. As of March 31, 2018, $1.3 million of the goodwill from the acquisition is expected to be deductible for federal income tax purposes.

Pro-forma financial information of the combined entities is not presented due to the immaterial impact of the financial results of the acquired restaurant on our consolidated financial statements.

The fair value measurement of tangible and intangible assets and liabilities as of the acquisition date is based on significant inputs not observed in the market and thus represents a Level 3 fair value measurement. Fair value measurements for reacquired franchise rights were determined using the income approach. Fair value measurements for property and equipment were determined using the cost approach.

Revenue from Contracts with Customers (Notes)

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue from Contracts with Customers

Revenue from contracts with customers consist primarily of royalties, advertising fund contributions, initial and renewal franchise fees and upfront fees from development agreements and international territory agreements. Our performance obligations under franchise agreements consist of (a) a franchise license, (b) pre-opening services, such as training, and (c) ongoing services, such as management of the Ad Fund, development of training materials and menu items and restaurant monitoring. These performance obligations are highly interrelated so we do not consider them to be individually distinct and therefore account for them under ASC 606 as a single performance obligation, which is satisfied by providing a right to use our intellectual property over the term of each franchise agreement.

Royalties, including franchisee contributions to advertising fund, are calculated as a percentage of franchise restaurant sales over the term of the franchise agreement. Initial and renewal franchise fees are payable by the franchisee prior to the restaurant opening or at the time of a renewal of an existing franchise agreement. Our franchise agreement royalties, inclusive of advertising fund contributions, represent sales-based royalties that are related entirely to our performance obligation under the franchise agreement and are recognized as franchise sales occur. Additionally, under ASC 606, initial and renewal franchise fees are recognized as revenue on a straight-line basis over the term of the respective agreement. Our performance obligation under development agreements and international territory agreements generally consists of an obligation to grant exclusive development rights over a stated term. These development rights are not distinct from franchise agreements, so upfront fees paid by franchisees for development rights are deferred and apportioned to each franchise restaurant opened by the franchisee. The pro rata amount apportioned to each restaurant is accounted for as an initial franchise fee.

The following table represents a disaggregation of revenue from contracts with customers for the thirteen weeks endedMarch 31, 2018 and April 1, 2017 (in thousands):

	Thirteen Weeks Ended
	March 31, 2018		April 1, 2017
			As adjusted*
Royalty revenue	$	15,386	$	12,691
Advertising fees and related income	8,605		7,268
Franchise fees	685		741

* See note 1.

Franchise fee, development fee, and international territory fee payments received by the Company are recorded as deferred revenue on the Consolidated Balance Sheet, which represents a contract liability. Deferred revenue is reduced as fees are recognized in revenue over the term of the franchise license for the respective restaurant. Approximately $10.2 million and $10.1 million of deferred revenue as of March 31, 2018 and December 30, 2017, respectively, relates to restaurants that have not yet opened, so the fees are not yet being amortized. The weighted average remaining amortization period for deferred franchise and renewal fees related to open restaurants is 7.8 years. The Company does not have any material contract assets as of March 31, 2018.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842). ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 will be effective beginning in the first quarter of 2019. Early adoption of ASU 2016-02 as of its issuance is permitted. This new guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We anticipate implementing the standard by taking advantage of the practical expedient option. The discounted minimum remaining rental payments will be the starting point for determining the right-of-use asset and lease liability. We expect that adoption of the new guidance will have a material impact on our consolidated balance sheets due to recognition of the right-of-use asset and lease liability related to our current operating leases. The process of evaluating the full impact of the new guidance on our consolidated financial statements and disclosures is ongoing, but we anticipate the initial evaluation of the impact will be completed in fiscal 2018.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740). ASU 2018-05 provides guidance on accounting for the income tax effects of the Tax Cuts and Jobs Act of 2017 (the “Act”), which impacts U.S. corporate tax rates, business-related exclusions, and deductions and credits. The Act also has tax consequences for many companies that operate internationally. The guidance in ASU 2018-05 addresses situations in which the accounting for certain income tax effects of the Act is incomplete by the time financial statements are issued for the reporting period that includes the enactment date of December 22, 2017. The new guidance requires companies to report provisional amounts if a reasonable estimate of the tax impact can be determined. If a provisional amount cannot be reasonably determined, the entity should continue to apply ASC Topic 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted.

The Company will continue to analyze additional information and guidance related to the Act as supplemental legislation, regulatory guidance, or evolving technical interpretations become available. The final impacts may differ from the recorded amounts as of March 31, 2018, and we will continue to refine such amounts within the measurement period provided by Staff Accounting Bulletin No. 118. We expect to complete our analysis no later than the fourth quarter of 2018.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance. The new guidance provides a single framework in which revenue is required to be recognized to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services.

The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting each prior reporting period presented and a cumulative effect adjustment, which was recorded as of the first day of 2016. The adoption changed the timing of recognition of initial franchise fees, development fees, territory fees for our international business and renewal and transfer fees, as well as the reporting of advertising fund contributions and related expenditures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that restricted cash and cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and a retrospective transition method is required. The Company adopted this new guidance effective the first day of fiscal year 2018, using the full retrospective transition method, which resulted in adjusting the Statement of Cash Flows for each prior period presented.
