Description of Business and Organization	Description of business and organization Dunkin’ Brands Group, Inc. (“DBGI”), together with its consolidated subsidiaries, is one of the world’s leading franchisors of restaurants serving coffee and baked goods, as well as ice cream, within the quick service restaurant segment of the restaurant industry. We franchise and license a system of both traditional and nontraditional quick service restaurants and, in limited circumstances, have owned and operated locations. Through our Dunkin’ Donuts brand, we franchise restaurants featuring coffee, donuts, bagels, breakfast sandwiches, and related products. Additionally, we license Dunkin’ Donuts brand products sold in certain retail outlets such as retail packaged coffee, Dunkin’ K-Cup® pods, and ready-to-drink bottled iced coffee. Through our Baskin-Robbins brand, we franchise restaurants featuring ice cream, frozen beverages, and related products. Additionally, we distribute Baskin-Robbins ice cream products to Baskin-Robbins franchisees and licensees in certain international markets. Throughout these unaudited consolidated financial statements, “Dunkin’ Brands,” “the Company,” “we,” “us,” “our,” and “management” refer to DBGI and its consolidated subsidiaries taken as a whole.

Revenue Recognition

Revenue Recognition	6 Months Ended
	Jun. 30, 2018
Revenue from Contract with Customer [Abstract]
Revenue Recognition	(a) Updated revenue recognition policies Franchise fees and royalty income Domestically, the Company sells individual franchises as well as territory agreements in the form of store development agreements (“SDAs”) that grant the right to develop restaurants in designated areas. The franchise agreements and SDAs typically require the franchisee to pay initial nonrefundable franchise fees prior to opening the respective restaurants and continuing fees, or royalty income, on a weekly basis based upon a percentage of franchisee gross sales. The initial term of domestic franchise agreements is typically 20 years. Prior to the end of the franchise term or as otherwise provided by the Company, a franchisee may elect to renew the term of a franchise agreement, and, if approved, will typically pay a renewal fee upon execution of the renewal term. If approved, a franchisee may transfer a franchise agreement or SDA to a new or existing franchisee, at which point a transfer fee is paid. Occasionally, the Company offers incentive programs to franchisees in conjunction with a franchise/license agreement, territory agreement, or renewal agreement. Internationally, the Company sells master franchise agreements that grant the master franchisee the right to develop and operate, and in some instances sub-franchise, a certain number of restaurants within a particular geographic area. The master franchisee is typically required to pay an upfront market entry fee upon entering into the master franchise agreement and an upfront initial franchise fee for each developed restaurant prior to each respective opening. For the Dunkin’ Donuts brand and in certain Baskin-Robbins international markets, the master franchisee will also pay continuing fees, or royalty income, generally on a monthly basis based upon a percentage of sales. Generally, the master franchise agreement serves as the franchise agreement for the underlying restaurants, and the initial franchise term provided for each restaurant typically ranges between 10 and 20 years. Generally, the franchise license granted for each individual restaurant within an arrangement represents a single performance obligation. Therefore, initial franchise fees and market entry fees for each arrangement are allocated to each individual restaurant and recognized over the term of the respective franchise agreement from the date of the restaurant opening. Royalty income is also recognized over the term of the respective franchise agreement based on the royalties earned each period as the underlying sales occur. Renewal fees are generally recognized over the renewal term for the respective restaurant from the start of the renewal period. Transfer fees are recognized over the remaining term of the franchise agreement beginning at the time of transfer. Additionally, for Baskin-Robbins international markets that do not pay a royalty, a portion of the consideration from sales of ice cream and other products is allocated to royalty income as consideration for the use of the franchise license, which is recognized when the related sales occur and is estimated based on royalty rates in effect for markets where the franchise license is sold on a standalone basis. Fees received or receivable that are expected to be recognized as revenue within one year are classified as current deferred revenue in the consolidated balance sheets. Advertising fees and related income Domestically and in limited international markets, franchise agreements typically require the franchisee to pay continuing advertising fees on a weekly basis based on a percentage of franchisee gross sales, which are recognized over the term of the respective franchise agreement based on the fees earned each period as the underlying sales occur. The Company and its franchisees sell gift cards that are redeemable for products in our Dunkin’ Donuts and Baskin-Robbins restaurants. The Company manages the gift card program, and therefore collects all funds from the activation of gift cards and reimburses franchisees for the redemption of gift cards in their restaurants. A liability for unredeemed gift cards, as well as historical gift certificates sold, is included in other current liabilities in the consolidated balance sheets. There are no expiration dates or service fees charged on the gift cards. While the franchisees continue to honor all gift cards presented for payment, the likelihood of redemption may be determined to be remote for certain cards due to long periods of inactivity. In these circumstances, the Company may recognize revenue from unredeemed gift cards (“breakage revenue”) if they are not subject to unclaimed property laws. For Dunkin’ Donuts gift cards enrolled in the DD Perks® Rewards loyalty program and other cards with expected similar redemption behavior, breakage is estimated and recognized at the point in time when the likelihood of redemption of any remaining card balance becomes remote, generally after a period of sufficient inactivity. Breakage on all other Dunkin’ Donuts gift cards and all Baskin-Robbins gift cards is estimated and recognized over time in proportion to actual gift card redemptions, based on historical redemption rates. The Company also collects gift card program service fees from franchisees to offset the costs to administer the gift card program. The gift card program service fees are based on the volume of gift card transactions processed and are recognized as the underlying transactions occur. Rental income Rental income for base rentals is recorded on a straight-line basis over the lease term, including the amortization of any tenant improvement dollars paid. The differences between the straight-line rent amounts and amounts receivable under the leases are recorded as deferred rent assets in current or long-term assets, as appropriate. Contingent rental income is recognized as earned, and any amounts received from lessees in advance of achieving stipulated thresholds are deferred until such thresholds are actually achieved. Deferred contingent rentals are recorded as deferred revenue in current liabilities in the consolidated balance sheets. Sales of ice cream and other products We distribute Baskin-Robbins ice cream products and, in limited cases, Dunkin’ Donuts products to franchisees in certain international locations. Revenue from the sale of ice cream and other products is recognized when title and risk of loss transfers to the buyer, which is generally upon delivery. Payment for ice cream and other products is generally due within a relatively short period of time subsequent to delivery. Other revenues Other revenues include fees generated by licensing our brand names and other intellectual property, as well as gains, net of losses and transactions costs, from the sales of restaurants that were not company-operated to new or existing franchisees. Licensing fees are recognized over the term of the expected license agreement, with sales-based license fees being recognized based on the amount earned each period as the underlying sales occur. Gains on the refranchise or sale of a restaurant are recognized over the term of the related agreement.

Additionally, the allocation of royalty income from sales of ice cream and other products is reported as "Other." (c) Contract balances Information about receivables and deferred revenue subject to ASC 606 is as follows (in thousands): June 30, December 30, Balance Sheet Classification Receivables $ 99,950 76,455 Accounts receivable, net and Notes and other receivables, net Deferred revenue: Current $ 30,550 27,724 Deferred revenue—current Long-term 366,246 361,458 Deferred revenue—long term Total $ 396,796 389,182 Receivables relate primarily to payments due for royalties, franchise fees, advertising fees, sales of ice cream and other products, and licensing fees. Deferred revenue primarily represents the Company’s remaining performance obligations under its franchise and license agreements for which consideration has been received or is receivable, and is generally recognized on a straight-line basis over the remaining term of the related agreement. The increase in the deferred revenue balance for the six months ended June 30, 2018 is primarily driven by cash payments received or due in advance of satisfying our performance obligations, offset by $16.7 million of revenues recognized that were included in the deferred revenue balance as of December 30, 2017. As of June 30, 2018 and December 30, 2017 , there were no contract assets from contracts with customers. (d) Transaction price allocated to remaining performance obligations Estimated revenue expected to be recognized in the future related to performance obligations that are either unsatisfied or partially satisfied at June 30, 2018 is as follows (in thousands): Fiscal year: 2018 (a) $ 16,541 2019 25,091 2020 23,851 2021 23,614 2022 23,341 Thereafter 247,568 Total $ 360,006 (a) Represents the estimate for remainder of fiscal year 2018 which excludes the six months ended June 30, 2018. The estimated revenue in the table above does not contemplate future franchise renewals or new franchise agreements for restaurants for which a franchise agreement or SDA does not exist at June 30, 2018 . Additionally, the table above excludes $61.9 million of consideration allocated to restaurants that are not yet open as of June 30, 2018 . The Company has applied the sales-based royalty exemption which permits exclusion of variable consideration in the form of sales-based royalties from the disclosure of remaining performance obligations in the table above. Additionally, the Company has applied the transition practical expedient that allows the Company to omit the above disclosures for the fiscal year ended December 30, 2017 . (e) Change in accounting principle In fiscal year 2018, the Company adopted new revenue recognition guidance which 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 the guidance using the full retrospective transition method which results in restating each prior reporting period presented. The restated amounts include the application of a practical expedient that permitted the Company to reflect the aggregate effect of all modifications that occurred prior to fiscal year 2016 when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price to the satisfied and unsatisfied performance obligations. The Company implemented new business processes, internal controls, and modified information technology systems to assist in the ongoing application of the new guidance. Franchise Fees The adoption of the new guidance changed the timing of recognition of initial franchise fees, including master license and territory fees for our international business, and renewal and transfer fees. Previously, these fees were generally recognized upfront upon either opening of the respective restaurant, when a renewal agreement became effective, or upon transfer of a franchise agreement. The new guidance generally requires these fees to be recognized over the term of the related franchise license for the respective restaurant. Additionally, transfer fees were previously included within other revenues, but are now included within franchise fees and royalty income in the consolidated statements of operations. The new guidance did not materially impact the recognition of royalty income. Advertising The adoption of the new guidance changed the reporting of advertising fund contributions from franchisees and the related advertising fund expenditures, which were not previously included in the consolidated statements of operations. The new guidance requires these advertising fund contributions and expenditures to be reported on a gross basis in the consolidated statements of operations. The assets and liabilities held by the advertising funds, which were previously reported as restricted assets and liabilities of advertising funds, respectively, are now included within the respective balance sheet caption to which the assets and liabilities relate. Additionally, advertising costs that have been incurred by the Company outside of the advertising funds were previously included within general and administrative expenses, net, but are now included within advertising expenses in the consolidated statements of operations. Previously, breakage from Dunkin’ Donuts and Baskin-Robbins gift cards was recorded as a reduction to general and administrative expenses, net, to offset the related gift card program costs. In accordance with the new guidance, breakage revenue is now reported on a gross basis in the consolidated statements of operations within advertising fees and related income, and the related gift card program costs are included in advertising expenses. Ice Cream Royalty Allocation The adoption of the new guidance requires a portion of sales of ice cream products to be allocated to royalty income as consideration for the use of the franchise license. As such, a portion of sales of ice cream and other products has been reclassified to franchise fees and royalty income in the consolidated statements of operations under the new guidance. This allocation has no impact on the timing of recognition of the related sales of ice cream products or royalty income. Other Revenue Transactions The adoption of the new guidance requires certain fees generated by licensing of our brand names and other intellectual property to be recognized over the term of the related agreement, including a one-time upfront license fee recognized in connection with the Dunkin’ K-Cup® pod licensing agreement in fiscal year 2015. Additionally, gains associated with the refranchise, sale, or transfer of restaurants that were not company-operated to new or existing franchisees are recognized over the term of the related agreement under the new guidance, instead of upon closing of the sale transaction or transfer.

Disclosure Summary Of Significant Accounting Policies Additional Information [Abstract]
Summary of Significant Accounting Policies	Summary of significant accounting policies (a) Unaudited consolidated financial statements The consolidated balance sheet as of June 30, 2018 , the consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2018 and July 1, 2017 , and the consolidated statements of cash flows for the six months ended June 30, 2018 and July 1, 2017 are unaudited. The accompanying unaudited consolidated financial statements include the accounts of DBGI and its consolidated subsidiaries and have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements. All significant transactions and balances between subsidiaries and affiliates have been eliminated in consolidation. In the opinion of management, all adjustments necessary for a fair presentation of such financial statements in accordance with U.S. GAAP have been recorded. Such adjustments consisted only of normal recurring items. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended December 30, 2017 , included in the Company’s Annual Report on Form 10-K. (b) Fiscal year The Company operates and reports financial information on a 52 - or 53 -week year on a 13 -week quarter basis with the fiscal year ending on the last Saturday in December and fiscal quarters ending on the 13th Saturday of each quarter (or 14th Saturday when applicable with respect to the fourth fiscal quarter). The data periods contained within the three- and six-month periods ended June 30, 2018 and July 1, 2017 reflect the results of operations for the 13-week and 26-week periods ended on those dates, respectively. Operating results for the three- and six-month periods ended June 30, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending December 29, 2018 . (c) Cash, cash equivalents, and restricted cash In accordance with the Company’s securitized financing facility, certain cash accounts have been established in the name of Citibank, N.A. (the “Trustee”) for the benefit of the Trustee and the noteholders, and are restricted in their use. The Company holds restricted cash which primarily represents (i) cash collections held by the Trustee, (ii) interest, principal, and commitment fee reserves held by the Trustee related to the Company’s notes (see note 4 ), and (iii) real estate reserves used to pay real estate obligations. Cash, cash equivalents, and restricted cash within the consolidated balance sheets that are included in the consolidated statements of cash flows as of June 30, 2018 and December 30, 2017 were as follows (in thousands): June 30, December 30, Cash and cash equivalents $ 367,940 1,018,317 Restricted cash 84,970 94,047 Restricted cash, included in Other assets 1,773 1,735 Total cash, cash equivalents, and restricted cash $ 454,683 1,114,099 (d) Fair value of financial instruments Financial assets and liabilities are categorized, based on the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to the quoted prices in active markets for identical assets and liabilities and lowest priority to unobservable inputs. Observable market data, when available, is required to be used in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 30, 2017 are summarized as follows (in thousands): June 30, 2018 December 30, 2017 Significant other observable inputs (Level 2) Total Significant other observable inputs (Level 2) Total Assets: Company-owned life insurance $ 11,033 11,033 10,836 10,836 Total assets $ 11,033 11,033 10,836 10,836 Liabilities: Deferred compensation liabilities $ 11,448 11,448 13,543 13,543 Total liabilities $ 11,448 11,448 13,543 13,543 The deferred compensation liabilities relate to the Dunkin’ Brands, Inc. non-qualified deferred compensation plans (“NQDC Plans”), which allow for pre-tax deferral of compensation for certain qualifying employees and directors. Changes in the fair value of the deferred compensation liabilities are derived using quoted prices in active markets of the asset selections made by the participants. The deferred compensation liabilities are classified within Level 2, as defined under U.S. GAAP, because their inputs are derived principally from observable market data by correlation to hypothetical investments. The Company holds company-owned life insurance policies to partially offset the Company’s liabilities under the NQDC Plans. The changes in the fair value of any company-owned life insurance policies are derived using determinable cash surrender value. As such, the company-owned life insurance policies are classified within Level 2, as defined under U.S. GAAP. The carrying value and estimated fair value of long-term debt as of June 30, 2018 and December 30, 2017 were as follows (in thousands): June 30, 2018 December 30, 2017 Carrying value Estimated fair value Carrying value Estimated fair value Financial liabilities Long-term debt $ 3,055,605 3,068,647 3,067,357 3,156,099 The estimated fair value of our long-term debt is estimated primarily based on current market rates for debt with similar terms and remaining maturities or current bid prices for our long-term debt. Judgment is required to develop these estimates. As such, the fair value of our long-term debt is classified within Level 2, as defined under U.S. GAAP. (e) Concentration of credit risk The Company is subject to credit risk through its accounts receivable consisting primarily of amounts due from franchisees and licensees for franchise fees, royalty income, advertising fees, and sales of ice cream and other products. In addition, we have note and lease receivables from certain of our franchisees and licensees. The financial condition of these franchisees and licensees is largely dependent upon the underlying business trends of our brands and market conditions within the quick service restaurant industry. This concentration of credit risk is mitigated, in part, by the large number of franchisees and licensees of each brand and the short-term nature of the franchise and license fee and lease receivables. As of June 30, 2018 and December 30, 2017 , one master licensee, including its majority-owned subsidiaries, accounted for approximately 20% and 11% , respectively, of total accounts and notes receivable. No individual franchisee or master licensee accounted for more than 10% of total revenues for any of the three and six month periods ended June 30, 2018 and July 1, 2017 . (f) Advertising expenses Advertising expenses in the consolidated statements of operations includes advertising expenses incurred by the Company, including those expenses incurred by the advertising funds and for the administration of the gift card program. The Company expenses production costs of commercial advertising upon first airing and expenses the costs of communicating the advertising in the period in which the advertising occurs. Costs of print advertising and certain promotion-related items are deferred and expensed the first time the advertising is displayed. Prepaid expenses and other current assets in the consolidated balance sheets include $17.3 million and $15.5 million at June 30, 2018 and December 30, 2017 , respectively, that was related to advertising. Advertising expenses are allocated to interim periods in relation to the related revenues. When revenues of the advertising fund exceed the related advertising expenses, advertising costs are accrued up to the amount of revenues. (g) Recent accounting pronouncements Recently adopted accounting pronouncements In February 2018, the Financial Accounting Standards Board (the “FASB”) issued new guidance allowing companies the option to reclassify from accumulated other comprehensive loss to accumulated deficit the stranded income tax effects resulting from the Tax Cuts and Jobs Act that was enacted on December 22, 2017. The Company early adopted this standard during the first quarter of fiscal year 2018 and has elected to present the change in the period of adoption. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued new guidance for revenue recognition related to contracts with customers (“ASC 606”), except for contracts within the scope of other standards, which supersedes nearly all existing revenue recognition guidance. We adopted this new guidance in fiscal year 2018. See note 3 for further disclosure of the impact of the new guidance. Recent accounting pronouncements not yet adopted In February 2016, the FASB issued new guidance for lease accounting, which replaces existing lease accounting guidance. The new guidance aims to increase transparency and comparability among organizations by requiring lessees to recognize lease assets and lease liabilities on the balance sheet and requiring disclosure of key information about leasing arrangements. This guidance is effective for the Company in fiscal year 2019 with early adoption permitted, and modified retrospective application is required with an option to not restate comparative periods in the period of adoption. The Company expects to adopt this new guidance in fiscal year 2019 without restating comparative periods, and expects that substantially all of its operating lease commitments will be subject to the new guidance and will be recognized as operating lease liabilities and right-of-use assets upon adoption, thereby having a material impact to its consolidated balance sheet. Though the majority of the assessment phase is complete, the Company continues to evaluate the impact the adoption of this new guidance will have on the Company's consolidated financial statements, as well as the impact on accounting policies and related disclosures. Additionally, the Company is in the process of implementing new accounting systems, business processes, and internal controls related to lease accounting to assist in the application of the new guidance. (h) Subsequent events Subsequent events have been evaluated through the date these consolidated financial statements were filed.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment information The Company is strategically aligned into two global brands, Dunkin’ Donuts and Baskin-Robbins, which are further segregated between U.S. operations and international operations. Additionally, the Company administers and directs the development of all advertising and promotional programs in the U.S. advertising funds. As such, the Company has determined that it has five reportable segments: Dunkin’ Donuts U.S., Dunkin’ Donuts International, Baskin-Robbins U.S., Baskin-Robbins International, and U.S. Advertising Funds. Dunkin’ Donuts U.S., Baskin-Robbins U.S., and Dunkin’ Donuts International primarily derive their revenues through royalty income and franchise fees. Baskin-Robbins U.S. also derives revenue through license fees from a third-party license agreement and rental income. Dunkin’ Donuts U.S. also derives revenue through rental income. Baskin-Robbins International primarily derives its revenues from sales of ice cream products, as well as royalty income, franchise fees, and license fees. U.S. Advertising Funds primarily derive revenues through continuing advertising fees from Dunkin’ Donuts and Baskin-Robbins franchisees. The operating results of each segment are regularly reviewed and evaluated separately by the Company’s senior management, which includes, but is not limited to, the chief executive officer. Senior management primarily evaluates the performance of its segments and allocates resources to them based on operating income adjusted for amortization of intangible assets, long-lived asset impairment charges, impairment of our equity method investments, and other infrequent or unusual charges, which does not reflect the allocation of any corporate charges. This profitability measure is referred to as segment profit. When senior management reviews a balance sheet, it is at a consolidated level. The accounting policies applicable to each segment are generally consistent with those used in the consolidated financial statements. Revenues for all operating segments include only transactions with unaffiliated customers and include no intersegment revenues. Revenues reported as “Other” include revenues earned through certain licensing arrangements with third parties in which our brand names are used, including the licensing fees earned from the Dunkin’ K-Cup® pod licensing agreement and sales of Dunkin’ Donuts branded ready-to-drink bottled iced coffee and retail packaged coffee, revenues generated from online training programs for franchisees, advertising fees and related income from international advertising funds, and breakage and other revenue related to the gift card program, all of which are not allocated to a specific segment.

Pursuant to the terms of the February 2018 ASR Agreements, the Company paid the financial institutions $650.0 million from cash on hand and received an initial delivery of 8,478,722 shares of the Company's common stock in February 2018, representing an estimate of 80% of the total shares expected to be delivered under the February 2018 ASR Agreements. At settlement, the financial institutions may be required to deliver additional shares of common stock to the Company or, under certain circumstances, the Company may be required to deliver shares of its common stock or may elect to make cash payment to the financial institutions. Final settlement of each of the February 2018 ASR Agreements is expected to be completed in the third quarter of fiscal year 2018. The Company accounts for treasury stock under the cost method based on the cost of the shares on the dates of repurchase plus any direct costs incurred. During the six months ended June 30, 2018 , the Company retired 8,478,722 shares of treasury stock repurchased under the February 2018 ASR Agreements. The repurchase and retirement of these shares of treasury stock resulted in a decrease in additional paid-in capital of $65.2 million and an increase in accumulated deficit of $455.1 million . Additionally, the Company recorded a decrease in additional paid-in capital of $130.0 million related to the remaining cash paid under the February 2018 ASR Agreements since the final settlement was not completed as of June 30, 2018 . (b) Equity incentive plans During the six months ended June 30, 2018 , the Company granted stock options to purchase 909,027 shares of common stock and 64,566 restricted stock units (“RSUs”) to certain employees and members of our board of directors. The stock options generally vest in equal annual amounts over a four -year period subsequent to the grant date, and have a maximum contractual term of seven years. The stock options were granted with an exercise price of $59.60 per share and have a weighted average grant-date fair value of $10.44 per share. The RSUs granted to employees and members of our board of directors vest in equal annual amounts over a three -year period and a one -year period, respectively, subsequent to the grant date and have a weighted average grant-date fair value of $58.33 per share. In addition, the Company granted 67,993 performance stock units (“PSUs”) to certain employees during the six months ended June 30, 2018 . These PSUs are generally eligible to cliff-vest approximately three years from the grant date. Of the total PSUs granted, 30,974 PSUs are subject to a service condition and a market vesting condition linked to the level of total shareholder return received by the Company’s shareholders during the performance period measured against the companies in the S&P 500 Composite Index (“TSR PSUs”). The remaining 37,019 PSUs granted are subject to a service condition and a performance vesting condition based on the level of adjusted operating income growth achieved over the performance period (“AOI PSUs”). The maximum vesting percentage that could be realized for each of the TSR PSUs and the AOI PSUs is 200% based on the level of performance achieved for the respective awards. All of the PSUs are also subject to a one -year post-vesting holding period. The TSR PSUs were valued based on a Monte Carlo simulation model to reflect the impact of the total shareholder return market condition, resulting in a grant-date fair value of $65.52 per share. The probability of satisfying a market condition is considered in the estimation of the grant-date fair value for TSR PSUs and the compensation cost is not reversed if the market condition is not achieved, provided the requisite service has been provided. The AOI PSUs have a grant-date fair value of $57.10 per share. Total compensation cost for the AOI PSUs is determined based on the most likely outcome of the performance condition and the number of awards expected to vest based on the outcome. Total compensation expense related to all share-based awards was $3.7 million and $3.8 million for the three months ended June 30, 2018 and July 1, 2017 , respectively, and $6.9 million and $7.2 million for the six months ended June 30, 2018 and July 1, 2017 , respectively, and is included in general and administrative expenses, net in the consolidated statements of operations. (c) Accumulated other comprehensive loss The changes in the components of accumulated other comprehensive loss were as follows (in thousands): Effect of foreign currency translation Other Accumulated other comprehensive loss Balance as of December 30, 2017 $ (8,084 ) (1,451 ) (9,535 ) Other comprehensive income (loss), net (5,744 ) 570 (5,174 ) Balance as of June 30, 2018 $ (13,828 ) (881 ) (14,709 ) (d) Dividends The Company paid a quarterly dividend of $0.3475 per share of common stock on March 21, 2018 and June 6, 2018 totaling approximately $28.6 million and $28.8 million , respectively. On July 26, 2018 , the Company announced that its board of directors approved the next quarterly dividend of $0.3475 per share of common stock payable September 5, 2018 to shareholders of record as of the close of business on August 27, 2018 .

The weighted average number of common shares in the common diluted earnings per share calculation for all periods excludes all contingently issuable equity awards for which the contingent vesting criteria were not yet met as of the fiscal period end. As of June 30, 2018 and July 1, 2017 , there were 256,350 and 150,000 shares, respectively, related to equity awards that were contingently issuable and for which the contingent vesting criteria were not yet met as of the fiscal period end. Additionally, the weighted average number of common shares in the common diluted earnings per share calculation excludes 982,054 and 1,123,482 equity awards for the three months ended June 30, 2018 and July 1, 2017 , respectively, and 1,432,676 and 1,629,480 equity awards for the six months ended June 30, 2018 and July 1, 2017 , respectively, as they would be antidilutive.

Commitments and Contingencies	Commitments and contingencies (a) S upply chain guarantees The Company has various supply chain agreements that provide for purchase commitments, the majority of which result in the Company being contingently liable upon early termination of the agreement. As of June 30, 2018 and December 30, 2017 , the Company was contingently liable under such supply chain agreements for approximately $119.9 million and $116.7 million , respectively. For certain supply chain commitments, as product is purchased by the Company’s franchisees over the term of the agreement, the amount of the guarantee is reduced. The Company assesses the risk of performing under each of these guarantees on a quarterly basis, and, based on various factors including internal forecasts, prior history, and ability to extend contract terms, we accrued an immaterial amount of reserves related to supply chain commitments as of June 30, 2018 and December 30, 2017 . (b) Letters of credit As of June 30, 2018 and December 30, 2017 , the Company had standby letters of credit outstanding for a total of $32.4 million and $32.3 million , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income taxes On December 22, 2017, the U.S. federal government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act significantly changes U.S. tax law by, among other things, reducing the corporate income tax rate from 35% to 21% effective January 1, 2018, establishing a territorial-style system for taxing foreign-source income of domestic multinational corporations, and imposing a one-time mandatory transition tax on deemed repatriated earnings of certain foreign joint ventures and subsidiaries. As a result of the Tax Act, the Company recorded a provisional net tax benefit of $143.4 million during fiscal year 2017. The provisional amount included a $145.1 million tax benefit for the remeasurement of certain U.S. deferred tax assets and liabilities. In addition, the provisional amount included a $1.7 million tax expense for the income tax on the deemed repatriation of unremitted foreign earnings, net of estimated foreign tax credits. The provisional net tax benefit was computed based on information available to the Company at the time. There have been no material changes to these provisional amounts during the six months ended June 30, 2018 , and there is still uncertainty as to the application of the Tax Act, including as it relates to state income taxes, because regulations and interpretations have not been released. In addition, certain estimates were used in computing the provisional amount, which will be finalized upon the filing of the Company’s 2017 U.S. federal tax return. As we complete our analysis of U.S. tax reform in fiscal year 2018, we may make adjustments to the provisional amounts, which may impact our provision for income taxes in the period in which the adjustments are made.

The Company holds restricted cash which primarily represents (i) cash collections held by the Trustee, (ii) interest, principal, and commitment fee reserves held by the Trustee related to the Company’s notes (see note 4 ), and (iii) real estate reserves used to pay real estate obligations. Cash, cash equivalents, and restricted cash within the consolidated balance sheets that are included in the consolidated statements of cash flows as of June 30, 2018 and December 30, 2017 were as follows (in thousands): June 30, December 30, Cash and cash equivalents $ 367,940 1,018,317 Restricted cash 84,970 94,047 Restricted cash, included in Other assets 1,773 1,735 Total cash, cash equivalents, and restricted cash $ 454,683 1,114,099
Fair Value of Financial Instruments	Fair value of financial instruments Financial assets and liabilities are categorized, based on the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to the quoted prices in active markets for identical assets and liabilities and lowest priority to unobservable inputs. Observable market data, when available, is required to be used in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 30, 2017 are summarized as follows (in thousands): June 30, 2018 December 30, 2017 Significant other observable inputs (Level 2) Total Significant other observable inputs (Level 2) Total Assets: Company-owned life insurance $ 11,033 11,033 10,836 10,836 Total assets $ 11,033 11,033 10,836 10,836 Liabilities: Deferred compensation liabilities $ 11,448 11,448 13,543 13,543 Total liabilities $ 11,448 11,448 13,543 13,543 The deferred compensation liabilities relate to the Dunkin’ Brands, Inc. non-qualified deferred compensation plans (“NQDC Plans”), which allow for pre-tax deferral of compensation for certain qualifying employees and directors. Changes in the fair value of the deferred compensation liabilities are derived using quoted prices in active markets of the asset selections made by the participants. The deferred compensation liabilities are classified within Level 2, as defined under U.S. GAAP, because their inputs are derived principally from observable market data by correlation to hypothetical investments. The Company holds company-owned life insurance policies to partially offset the Company’s liabilities under the NQDC Plans. The changes in the fair value of any company-owned life insurance policies are derived using determinable cash surrender value. As such, the company-owned life insurance policies are classified within Level 2, as defined under U.S. GAAP. The carrying value and estimated fair value of long-term debt as of June 30, 2018 and December 30, 2017 were as follows (in thousands): June 30, 2018 December 30, 2017 Carrying value Estimated fair value Carrying value Estimated fair value Financial liabilities Long-term debt $ 3,055,605 3,068,647 3,067,357 3,156,099 The estimated fair value of our long-term debt is estimated primarily based on current market rates for debt with similar terms and remaining maturities or current bid prices for our long-term debt. Judgment is required to develop these estimates. As such, the fair value of our long-term debt is classified within Level 2, as defined under U.S. GAAP.
Concentration of Credit Risk	Concentration of credit risk The Company is subject to credit risk through its accounts receivable consisting primarily of amounts due from franchisees and licensees for franchise fees, royalty income, advertising fees, and sales of ice cream and other products. In addition, we have note and lease receivables from certain of our franchisees and licensees. The financial condition of these franchisees and licensees is largely dependent upon the underlying business trends of our brands and market conditions within the quick service restaurant industry. This concentration of credit risk is mitigated, in part, by the large number of franchisees and licensees of each brand and the short-term nature of the franchise and license fee and lease receivables. As of June 30, 2018 and December 30, 2017 , one master licensee, including its majority-owned subsidiaries, accounted for approximately 20% and 11% , respectively, of total accounts and notes receivable. No individual franchisee or master licensee accounted for more than 10% of total revenues for any of the three and six month periods ended June 30, 2018 and July 1, 2017 .
Advertising Expenses	Advertising expenses Advertising expenses in the consolidated statements of operations includes advertising expenses incurred by the Company, including those expenses incurred by the advertising funds and for the administration of the gift card program. The Company expenses production costs of commercial advertising upon first airing and expenses the costs of communicating the advertising in the period in which the advertising occurs. Costs of print advertising and certain promotion-related items are deferred and expensed the first time the advertising is displayed. Prepaid expenses and other current assets in the consolidated balance sheets include $17.3 million and $15.5 million at June 30, 2018 and December 30, 2017 , respectively, that was related to advertising. Advertising expenses are allocated to interim periods in relation to the related revenues. When revenues of the advertising fund exceed the related advertising expenses, advertising costs are accrued up to the amount of revenues.
Recent Accounting Pronouncements	Recent accounting pronouncements Recently adopted accounting pronouncements In February 2018, the Financial Accounting Standards Board (the “FASB”) issued new guidance allowing companies the option to reclassify from accumulated other comprehensive loss to accumulated deficit the stranded income tax effects resulting from the Tax Cuts and Jobs Act that was enacted on December 22, 2017. The Company early adopted this standard during the first quarter of fiscal year 2018 and has elected to present the change in the period of adoption. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued new guidance for revenue recognition related to contracts with customers (“ASC 606”), except for contracts within the scope of other standards, which supersedes nearly all existing revenue recognition guidance. We adopted this new guidance in fiscal year 2018. See note 3 for further disclosure of the impact of the new guidance. Recent accounting pronouncements not yet adopted In February 2016, the FASB issued new guidance for lease accounting, which replaces existing lease accounting guidance. The new guidance aims to increase transparency and comparability among organizations by requiring lessees to recognize lease assets and lease liabilities on the balance sheet and requiring disclosure of key information about leasing arrangements. This guidance is effective for the Company in fiscal year 2019 with early adoption permitted, and modified retrospective application is required with an option to not restate comparative periods in the period of adoption. The Company expects to adopt this new guidance in fiscal year 2019 without restating comparative periods, and expects that substantially all of its operating lease commitments will be subject to the new guidance and will be recognized as operating lease liabilities and right-of-use assets upon adoption, thereby having a material impact to its consolidated balance sheet. Though the majority of the assessment phase is complete, the Company continues to evaluate the impact the adoption of this new guidance will have on the Company's consolidated financial statements, as well as the impact on accounting policies and related disclosures. Additionally, the Company is in the process of implementing new accounting systems, business processes, and internal controls related to lease accounting to assist in the application of the new guidance.
