Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION INTERIM FINANCIAL STATEMENTS — The accompanying unaudited Condensed Consolidated Financial Statements of Flowers Foods, Inc. (the “company”, “Flowers Foods”, “Flowers”, “us”, “we”, or “our”) have been prepared by the company’s management in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and applicable rules and regulations of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Accordingly, they do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements included herein contain all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the company’s financial position, results of operations and cash flows. The results of operations for the twelve and twenty-eight weeks ended July 15, 2017 and July 16, 2016 are not necessarily indicative of the results to be expected for a full fiscal year. The Condensed Consolidated Balance Sheet at December 31, 2016 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 (the “Form 10-K”). ESTIMATES — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The company believes the following critical accounting estimates affect its more significant judgments and estimates used in the preparation of its consolidated financial statements: revenue recognition, derivative instruments, valuation of long-lived assets, goodwill and other intangible assets, self-insurance reserves, income tax expense and accruals, pension obligations, stock-based compensation, and commitments and contingencies. These estimates are summarized in the Form 10-K. REPORTING PERIODS — The company operates on a 52-53 week fiscal year ending the Saturday nearest December 31. Fiscal 2017 consists of 52 weeks, with the company’s quarterly reporting periods as follows: first quarter ended April 22, 2017 (sixteen weeks), second quarter ended July 15, 2017 (twelve weeks), third quarter ending October 7, 2017 (twelve weeks) and fourth quarter ending December 30, 2017 (twelve weeks). SEGMENTS — Flowers Foods currently operates two business segments: a direct-store-delivery (“DSD”) segment (“DSD Segment”) and a warehouse delivery segment (“Warehouse Segment”). The DSD Segment (85% of total year to date sales) currently operates 39 plants that produce a wide variety of fresh bakery foods, including fresh breads, buns, rolls, tortillas, and snack cakes. These products are sold through a DSD route delivery system to retail and foodservice customers in the East, South, Southwest, California, and select markets in the Midwest, Pacific Northwest, Nevada, and Colorado. The Warehouse Segment (15% of total year to date sales) currently operates ten plants that produce snack cakes, breads and rolls for national retail, foodservice, vending, and co-pack customers and deliver through customers’ warehouse channels. On May 3, 2017, the company announced an enhanced organizational structure designed to provide greater focus on the company’s strategic objectives, emphasize brand growth and innovation in line with a national branded food company, drive enhanced accountability, reduce costs, and strengthen long-term strategy. The new organizational structure establishes two business units (“BUs”), Fresh Bakery and Specialty/Snacking, and realigns key leadership roles. The new structure also provides for centralized marketing, sales, supply chain, shared-services/administrative, and corporate strategy functions, each with clearly defined roles and responsibilities. The company intends to transition to the new structure over the next several months with full implementation expected during fiscal 2018. The current DSD and warehouse segmentation will remain until the new structure is in place. SIGNIFICANT CUSTOMER — Following is the effect that our largest customer, Walmart/Sam’s Club, had on the company’s sales for the twelve and twenty-eight weeks ended July 15, 2017 and July 16, 2016. Walmart/Sam’s Club is the only customer to account for greater than 10% of the company’s sales. For the Twelve Weeks Ended For the Twenty-Eight Weeks Ended July 15, 2017 July 16, 2016 July 15, 2017 July 16, 2016 (% of Sales) (% of Sales) DSD Segment 18.3 17.6 17.7 16.9 Warehouse Segment 2.3 2.6 2.4 2.7 Total 20.6 20.2 20.1 19.6 Walmart/Sam’s Club is our only customer with a balance greater than 10% of outstanding trade receivables. Its percentage of trade receivables was 19.8% and 18.8%, on a consolidated basis, as of July 15, 2017 and December 31, 2016, respectively. No other customer accounted for greater than 10% of the company’s outstanding trade receivables. SIGNIFICANT ACCOUNTING POLICIES — There were no significant changes to our critical accounting policies for the quarter ended July 15, 2017 from those disclosed in the Form 10-K.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	3. RECENT ACCOUNTING PRONOUNCEMENTS Recently adopted accounting pronouncements In July 2015, the Financial Accounting Standards Board (“FASB”) issued guidance that entities should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The company adopted this guidance as of January 1, 2017 (the first day of our fiscal 2017) and the guidance was applied on a prospective basis. The impact since adoption has been immaterial. In March 2016, the FASB issued guidance to simplify several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statements of cash flows. A summary at adoption is presented below: • Accounting for income taxes . The new guidance eliminates the additional paid-in capital pool concept and requires that excess tax benefits and tax deficiencies be recorded in the income statement as a component of income tax expense when awards are settled. The recognition of excess tax benefits and deficiencies in the income statement will be applied prospectively. The company adopted the presentation of excess tax benefits on the statements of cash flows under the retrospective transition method. This is presented as a change from a financing activity to a reconciling cash flow item for operating activities for the twenty-eight weeks ended July 16, 2016. The net impact during the twelve weeks ended July 15, 2017 for all exercised and vested awards was immaterial. The net impact during the twenty-eight weeks ended July 15, 2017 for all exercised and vested awards was $1.6 million as tax expense. • Accounting for share-based payment forfeitures . The new guidance permits entities to make a company-wide accounting policy election to either estimate forfeitures each period, as was required, or to account for forfeitures as they occur. The company’s forfeitures, before adoption, were immaterial and had been recorded as they occurred. At adoption, the company will continue to recognize forfeitures as they occur. • Accounting for statutory tax withholding requirements . The new guidance permits companies to withhold an amount up to the employees’ maximum individual tax rate in the relevant jurisdiction, without resulting in liability classification of the award. The company currently withholds the statutory minimum and will continue to do so until we complete an analysis of the required system changes which will allow the company to change its withholding practices in accordance with the new guidance. This amendment did not impact the company. Amendments related to the presentation of employee taxes paid on the statement of cash flows when the employer withholds shares to meet the minimum statutory did not impact the company since we already reported cash flows in accordance with the new guidance. The table below presents the impact to the Condensed Consolidated Statements of Cash Flows at adoption (amounts in thousands): For the Twenty-Eight Weeks Ended Post-adoption* July 16, 2016 July 16, 2016 CASH FLOWS PROVIDED BY (DISBURSED FOR) OPERATING ACTIVITIES: Other $ (3,730 ) $ (1,604 ) Net cash provided by operating activities 193,857 195,297 CASH FLOWS PROVIDED BY (DISBURSED FOR) FINANCING ACTIVITIES: Excess windfall tax benefit related to share-based payment awards 2,126 — Net cash disbursed for financing activities $ (159,895 ) $ (162,021 ) * The Post-adoption column in the table above presents the amounts inclusive of the revisions discussed in Note 2, Financial Statement Revisions See Note 13, Stock-Based Compensation Accounting pronouncements not yet adopted In May 2014, the FASB issued guidance for recognizing revenue in contracts with customers. This guidance requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. There are five steps outlined in the guidance to achieve this core principle. This guidance was originally effective January 1, 2017, the first day of our fiscal 2017. In July 2015, the FASB issued a deferral for one year, making the effective date December 31, 2017, the first day of our fiscal 2018. In March 2016, the FASB amended the initial guidance to clarify the implementation guidance on principal versus agent considerations. In April 2016, the FASB amended the initial guidance to clarify the identification of performance conditions and the licensing implementation guidance. In May 2016, the FASB amended the initial guidance to update certain narrow scopes within the revenue recognition guidance. In December 2016, the FASB amended the initial guidance for technical corrections and improvements. Early application is permitted, but not before January 1, 2017. Entities will have the option to apply the final standard retrospectively or use a modified retrospective method, recognizing the cumulative effect of the standards in retained earnings at the date of initial application. An entity will not restate prior periods if it uses the modified retrospective method, but will be required to disclose the amount by which each financial statement line item is affected in the current reporting period by the application of the standard as compared to the guidance in effect prior to the change, as well as reasons for significant changes. The company first intends to report the updated standard in its first quarter filing of fiscal 2018. The company is currently in the process of assessing the adoption methodology to apply and, as of July 15, 2017, has not selected a transition method. The company is currently evaluating the impact that implementing this standard will have on its financial statements, related disclosures and our internal control over financial reporting as well as whether the effect will be material to our revenue. Our initial review found four areas that will continue to be assessed through fiscal 2017. The areas include how to account for pay-by-scan sales and estimated stale charges, whether revenue for a transaction involving a third party is reported net or gross, and the timing of income recognition on the sale of territories. These are not intended to be a complete inventory of the potentially impacted types of transactions, but we have identified these for further study. More impacted revenue sources may be discovered as we continue our review. The company does not typically enter into long-term revenue contracts and does not anticipate those areas to be material. The company does not anticipate significant changes to our systems or processes upon adoption. Additional disclosure about revenue sources, as well as assumptions about recognition timing, may be necessary. In February 2016, the FASB issued guidance that requires an entity to recognize lease liabilities and a right-of-use asset for virtually all leases (other than those that meet the definition of a short-term lease) on the balance sheet and to disclose key information about the entity’s leasing arrangements. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods, with earlier adoption permitted. This guidance must be adopted using a modified retrospective approach for all leases existing at, or entered into after, the date of initial adoption, with an option to elect to use certain transition relief. The company intends to adopt the updated standard in the first quarter of fiscal 2019. The company currently has significant operating leases with our fiscal 2016 lease expense totaling $97.4 million. The company is evaluating the potential impact of this guidance on our Consolidated Financial Statements. In August 2016, the FASB issued guidance on the classification of certain cash receipts and payments in the statements of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted. The guidance must be applied retrospectively to all periods presented but may be applied prospectively if retrospective application would be impracticable. The company is currently evaluating the impact that the new guidance will have on our Consolidated Financial Statements. In January 2017, the FASB issued guidance to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those period. Early application is allowed for transactions that have not been reported in financial statements that have been issued or made available for issuance. This guidance shall be applied prospectively at adoption. This guidance will impact the company’s assessment of the acquisition of either an asset or a business in future transactions beginning in our fiscal 2018. In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. The guidance removed Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Companies will still have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. This guidance will be applied prospectively. Companies are required to disclose the nature of and reason for the change in accounting principle upon transition. That disclosure shall be provided in the first annual reporting period and in the interim period within the first annual reporting period when the company adopts this guidance. This change to the guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted after January 1, 2017. The company is currently evaluating when this guidance will be adopted and the impact on our Consolidated Financial Statements. In March 2017, the FASB issued guidance that requires all employers to separately present the service cost component from the other pension and postretirement benefit cost components in the income statement. Service cost will now be presented with other employee compensation costs in operating income or capitalized in assets, as appropriate. The other components reported in the income statement will be reported separate from the service cost and outside of income from operations. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within those periods. Early adoption was permitted as of the beginning of an annual reporting period for which financial statements were not issued or made available for issuance. However, early adoption is only allowed in the first interim period presented in a fiscal year; therefore, early adoption was only permitted in our first quarter of fiscal 2017. The guidance is required to be applied on a retrospective basis for the presentation of the service cost component and the other components of net benefit cost, and on a prospective basis for the capitalization of only the service cost component of net benefit cost. The company currently does not capitalize our pension cost. This guidance will impact the company. The company plans to adopt this standard in the first quarter of fiscal 2018. Our plan costs (including defined benefit and post-retirement plans) for the twelve and twenty-eight weeks ended July 15, 2017 are presented in the table below (amounts in thousands): For the Twelve Weeks Ended For the Twenty-Eight Weeks Ended July 15, 2017 July 15, 2017 Service cost to be reported in operating income $ 233 $ 545 Components to be reported outside of operating income (1,442 ) (3,366 ) Total pension cost (income) $ (1,209 ) $ (2,821 ) In May 2017, the FASB issued guidance to provide clarity and reduce diversity in practice for changes to the terms and conditions of a share-based payment award. This amendment provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments to this guidance are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The amendments shall be applied prospectively to an award modified on or after the adoption date. The company is currently evaluating when this guidance will be adopted and the impact on our Consolidated Financial Statements. We have reviewed other recently issued accounting pronouncements and concluded that either they are not applicable to our business or that no material effect is expected upon future adoption.

Divestiture	4. DIVESTITURE On January 14, 2017, the company completed the sale of a non-core mix manufacturing business located in Cedar Rapids, Iowa for $44.0 million, an amount reduced by a working capital adjustment of $2.8 million, for net proceeds of $41.2 million. This resulted in a gain on sale of $28.9 million, which was recognized in the first quarter of fiscal 2017. The gain on the sale is presented on the Condensed Consolidated Statements of Income on the ‘Gain on divestiture’ line item. The mix manufacturing business was a small component of our Warehouse Segment and the disposal of this business does not represent a strategic shift in the segment’s operations or financial results.

These trademarks are classified as indefinite-lived because we believe they are well established brands, many older than forty years old, with a long history and well defined markets. In addition, we are continuing to use these brands both in their original markets and throughout our expansion territories. We believe these factors support an indefinite-life. We perform an annual impairment analysis, or on an interim basis if the facts and circumstances change, to determine if the trademarks are realizing their expected economic benefits. The company is currently undergoing an enterprise-wide business and operational review. The review is ongoing and includes a brand rationalization study that impacts certain trademarks’ future revenue projections. The review has not been fully finalized and the results of the review may impact future periods.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	7. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying value of cash and cash equivalents, accounts receivable, and short-term debt approximates fair value because of the short-term maturity of the instruments. Notes receivable are entered into in connection with the purchase of independent distributors’ distribution rights by independent distributors. These notes receivable are recorded in the Condensed Consolidated Balance Sheets at carrying value, which represents the closest approximation of fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As a result, the appropriate interest rate that should be used to estimate the fair value of the distribution rights notes is the prevailing market rate at which similar loans would be made to independent distributors with similar credit ratings and for the same maturities. However, the company finances approximately 3,800 independent distributors, all with varied financial histories and credit risks. Considering the diversity of credit risks among the independent distributors, the company has no method to accurately determine a market interest rate to apply to the notes. The distribution rights are generally purchased with a 5% down payment with the remainder financed for up to ten years. The distribution rights notes are collateralized by the independent distributors’ distribution rights. The company maintains a wholly-owned subsidiary to assist in financing the distribution rights purchase activities if requested by new independent distributors, using the distribution rights and certain associated assets as collateral. These notes receivable earn interest at a fixed rate. Interest income for the distributor notes receivable was as follows (amounts in thousands): Interest Income For the twelve weeks ended July 15, 2017 $ 5,158 For the twelve weeks ended July 16, 2016 $ 4,639 For the twenty-eight weeks ended July 15, 2017 $ 11,735 For the twenty-eight weeks ended July 16, 2016 $ 10,929 At July 15, 2017, December 31, 2016, and July 16, 2016 respectively, the carrying value of the distributor notes was as follows (amounts in thousands): July 15, 2017 December 31, 2016 July 16, 2016 Distributor notes receivable $ 191,684 $ 175,984 $ 170,489 Current portion of distributor notes receivable recorded in accounts and notes receivable, net 22,410 21,060 20,750 Long-term portion of distributor notes receivable $ 169,274 $ 154,924 $ 149,739 At July 15, 2017 and December 31, 2016, respectively, the company has evaluated the collectability of the distributor notes and determined that a reserve is not necessary. Payments on these distributor notes are collected by the company weekly in conjunction with the distributor settlement process. The fair value of the company’s variable rate debt at July 15, 2017 approximates the recorded value. The fair value of the company’s 3.5% senior notes due 2026 (“2026 notes”) and 4.375% senior notes due 2022 (“2022 notes”), as discussed in Note 9, Debt and Other Obligations Carrying Value Fair Value Level 2026 notes $ 394,714 $ 395,700 2 2022 notes $ 397,718 $ 429,120 2 For fair value disclosure information about our derivative assets and liabilities see Note 8, Derivative Financial Instruments

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	8. DERIVATIVE FINANCIAL INSTRUMENTS The company measures the fair value of its derivative portfolio by using the price that would be received to sell an asset or paid to transfer a liability in the principal market for that asset or liability. These measurements are classified into a hierarchy by the inputs used to perform the fair value calculation as follows: Level 1: Fair value based on unadjusted quoted prices for identical assets or liabilities at the measurement date Level 2: Modeled fair value with model inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly Level 3: Modeled fair value with unobservable model inputs that are used to estimate the fair value of the asset or liability Commodity Risk The company enters into commodity derivatives designated as cash-flow hedges of existing or future exposure to changes in commodity prices. The company’s primary raw materials are flour, sweeteners and shortening, along with pulp, paper and petroleum-based packaging products. Natural gas, which is used as oven fuel, is also an important commodity input for production. As of July 15, 2017, the company’s hedge portfolio contained commodity derivatives, which are recorded in the following accounts with fair values measured as indicated (amounts in thousands): Level 1 Level 2 Level 3 Total Assets: Other current $ 6,245 $ — $ — $ 6,245 Other long-term 164 — — 164 Total 6,409 — — 6,409 Liabilities: Other long-term (127 ) — — (127 ) Total (127 ) — — (127 ) Net Fair Value $ 6,282 $ — $ — $ 6,282 As of December 31, 2016, the company’s commodity hedge portfolio contained derivatives, which are recorded in the following accounts with fair values measured as indicated (amounts in thousands): Level 1 Level 2 Level 3 Total Assets: Other current $ 1,576 $ — $ — $ 1,576 Other long-term 35 — — 35 Total 1,611 — — 1,611 Liabilities: Other current (2,435 ) — — (2,435 ) Total (2,435 ) — — (2,435 ) Net Fair Value $ (824 ) $ — $ — $ (824 ) The positions held in the portfolio are used to hedge economic exposure to changes in various raw material prices and effectively fix, or limit increases in, prices for a period of time extending primarily into fiscal 2019. These instruments are designated as cash-flow hedges. The effective portion of changes in the fair value for these derivatives is reported in AOCI, and any ineffective portion of changes in the fair value for such derivatives is recorded in current period earnings in selling, distribution and administrative expenses. All of the company-held commodity derivatives at July 15, 2017 and December 31, 2016, respectively, qualified for hedge accounting. Interest Rate Risk The company entered into treasury rate locks on August 5, 2016 and August 8, 2016 to fix the interest rate for the 2026 notes issued on September 28, 2016. The derivative positions were closed when the debt was priced on September 23, 2016 with a cash settlement net receipt of $1.0 million that offset changes in the benchmark treasury rate between execution of the treasury rate locks and the debt pricing date. These rate locks were designated as a cash flow hedge. During fiscal 2016, the company recognized $0.1 million of ineffectiveness due to issuing the debt earlier than the settlement date of the treasury locks. The ineffectiveness amount was reported as a selling, distribution, and administrative expense in our Condensed Consolidated Statements of Income. The company entered into a treasury rate lock on March 28, 2012 to fix the interest rate for the 2022 notes issued on April 3, 2012. The derivative position was closed when the debt was priced on March 29, 2012 with a cash settlement net receipt of $3.1 million that offset changes in the benchmark treasury rate between the execution of the treasury rate lock and the debt pricing date. This treasury rate lock was designated as a cash flow hedge. The following table outlines the company’s derivatives, which were hedging the risk of changes in forecasted interest payments on forecasted issuance of long-term debt (amounts in thousands, before tax, and an asset is a positive value and a liability is a negative value): Terminated Description Aggregate Notional Amount Fair Value When Terminated Fair Value Deferred in AOCI(1) Ineffective Portion at Termination April/2012 Treasury lock $ 500,000 $ (3,137 ) $ 2,510 $ 627 September/2016 Treasury lock $ 200,000 $ 1,298 $ (1,298 ) $ — September/2016 Treasury lock $ 150,000 $ (323 ) $ 215 $ 108 (1) The amount reported in AOCI is reclassified to interest expense as interest payments are made on the related notes through the maturity date.

Certain of our banks allow us to delay funding of issued checks until the checks are presented for payment. The delay in funding results in a temporary source of financing from the bank. The activity related to bank overdrafts is shown as a financing activity in our Condensed Consolidated Statements of Cash Flows. Bank overdrafts are included in other current liabilities on our Condensed Consolidated Balance Sheets. As of July 15, 2017 and December 31, 2016, the bank overdraft balance was $13.9 million and $19.9 million, respectively. The company also had standby letters of credit (“LOCs”) outstanding of $8.7 million and $9.1 million at July 15, 2017 and December 31, 2016, respectively, which reduce the availability of funds under the credit facility (as defined below). The outstanding LOCs are for the benefit of certain insurance companies and lessors. None of the LOCs are recorded as a liability on the Condensed Consolidated Balance Sheets. 2026 Notes, Accounts Receivable Securitization Facility, 2022 Notes, and Credit Facility 2026 Notes . On September 28, 2016, the company issued $400.0 million of senior notes. The company will pay semiannual interest on the 2026 notes on each April 1 and October 1, beginning on April 1, 2017, and the 2026 notes will mature on October 1, 2026. The notes bear interest at 3.500% per annum. The 2026 notes are subject to interest rate adjustments if either Moody’s or S&P downgrades (or downgrades and subsequently upgrades) the credit rating assigned to the 2026 notes. On any date prior to July 1, 2026, the company may redeem some or all of the notes at a price equal to the greater of (1) 100% of the principal amount of the notes redeemed and (2) a “make-whole” amount plus, in each case, accrued and unpaid interest. The make-whole amount is equal to the sum of the present values of the remaining scheduled payments of principal and interest on the 2026 notes to be redeemed that would be due if such notes matured July 1, 2026 (exclusive of interest accrued to, but not including, the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the treasury rate (as defined in the indenture governing the notes), plus 30 basis points, plus in each case accrued and unpaid interest. At any time on or after July 1, 2026, the company may redeem some or all of the 2026 notes at a price equal to 100% of the principal amount of the notes redeemed plus accrued and unpaid interest. If the company experiences a “change of control triggering event” (which involves a change of control of the company and the related rating of the notes below investment grade), it is required to offer to purchase the notes at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest thereon unless the company exercised its option to redeem the notes in whole. The 2026 notes are also subject to customary restrictive covenants for investment grade debt, including certain limitations on liens and sale and leaseback transactions. The face value of the 2026 notes is $400.0 million. There was a debt discount representing the difference between the net proceeds, after expenses, received upon issuance of debt and the amount repayable at its maturity. The company also paid issuance costs of $3.6 million (including underwriting fees and legal fees) on the 2026 notes. Debt issuance costs and the debt discount are being amortized to interest expense over the term of the 2026 notes. As of July 15, 2017, and December 31, 2016, respectively, the company was in compliance with all restrictive covenants under the indenture governing the 2026 notes. The table below presents the debt discount, underwriting fees and the legal and other fees for issuing the 2026 notes (amounts in thousands): Amount at Issuance Debt discount $ 2,108 Underwriting, legal, and other fees 3,634 Total fees $ 5,742 Accounts Receivable Securitization Facility . On July 17, 2013, the company entered into an accounts receivable securitization facility (the “facility”). On August 7, 2014, the company entered into an amendment to the facility. The amendment (i) increased the revolving commitments under the facility to $200.0 million from $150.0 million, (ii) extended the term one year to July 17, 2016, and (iii) made certain other conforming changes. On December 17, 2014, the company executed a second amendment to the facility to add a bank to the lending group. The original commitment amount was split between the original lender and the new lender in the proportion of 62.5% for the original lender and 37.5% for the new lender. This modification, which was accounted for as an extinguishment of the debt, resulted in a charge of $0.1 million, or 37.5%, of the unamortized financing costs. On August 20, 2015, the company executed a third amendment to the facility to extend the term to August 11, 2017 and to add a leverage pricing grid. This amendment was accounted for as a modification. On September 30, 2016, the company executed a fourth amendment to the facility to extend the term to September 28, 2018. This amendment was accounted for as a modification. Under the facility, a wholly-owned, bankruptcy-remote subsidiary purchases, on an ongoing basis, substantially all trade receivables. As borrowings are made under the facility, the subsidiary pledges the receivables as collateral. In the event of liquidation of the subsidiary, its creditors would be entitled to satisfy their claims from the subsidiary’s pledged receivables prior to distributions of collections to the company. We include the subsidiary in our Condensed Consolidated Financial Statements. The facility contains certain customary representations and warranties, affirmative and negative covenants, and events of default. There was $10.0 million and $95.0 million outstanding under the facility as of July 15, 2017 and December 31, 2016, respectively. As of July 15, 2017 and December 31, 2016, respectively, the company was in compliance with all restrictive covenants under the facility. The company currently has $180.8 million available under its facility for working capital and general corporate purposes. Amounts available for withdrawal under the facility are determined as the lesser of the total commitments and a formula derived amount based on qualifying trade receivables. Optional principal repayments may be made at any time without premium or penalty. Interest is due two days after our reporting periods end in arrears on the outstanding borrowings and is computed as the cost of funds rate plus an applicable margin of 85 basis points. An unused fee of 30 basis points is applicable on the unused commitment at each reporting period. Financing costs paid at inception of the facility and at the time amendments are executed are being amortized over the life of the facility. The balance of unamortized financing costs was $0.2 million and $0.2 million on July 15, 2017 and December 31, 2016, respectively, and are recorded in other assets on the Condensed Consolidated Balance Sheets. 2022 Notes . On April 3, 2012, the company issued $400.0 million of senior notes. The company pays semiannual interest on the 2022 notes on each April 1 and October 1, beginning on October 1, 2012, and the 2022 notes will mature on April 1, 2022. The 2022 notes bear interest at 4.375% per annum. On any date prior to January 1, 2022, the company may redeem some or all of the 2022 notes at a price equal to the greater of (1) 100% of the principal amount of the notes redeemed and (2) a “make-whole” amount plus, in each case, accrued and unpaid interest. The make-whole amount is equal to the sum of the present values of the remaining scheduled payments of principal thereof (not including any interest accrued thereon to, but not including, the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the treasury rate (as defined in the indenture governing the notes), plus 35 basis points, plus in each case, unpaid interest accrued thereon to, but not including, the date of redemption. At any time on or after January 1, 2022, the company may redeem some or all of the 2022 notes at a price equal to 100% of the principal amount of the 2022 notes redeemed plus accrued and unpaid interest. If the company experiences a “change of control triggering event” (which involves a change of control of the company and the related rating of the notes below investment grade), it is required to offer to purchase the 2022 notes at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest thereon unless the company exercised its option to redeem the 2022 notes in whole. The 2022 notes are also subject to customary restrictive covenants for investment grade debt, including certain limitations on liens and sale and leaseback transactions. The face value of the 2022 notes is $400.0 million and the debt discount on the 2022 notes at issuance was $1.0 million. The company paid issuance costs (including underwriting fees and legal fees) on the 2022 notes of $3.9 million. The issuance costs and the debt discount are being amortized to interest expense over the term of the 2022 notes. As of July 15, 2017 and December 31, 2016, the company was in compliance with all restrictive covenants under the indenture governing the 2022 notes. Credit Facility . On April 19, 2016, the company amended its senior unsecured credit facility (the “credit facility”), which was accounted for as a modification of the debt, that addressed changes in law affecting the terms of the existing agreement. In addition, the amendment increases the highest applicable margin applicable to base rate loans to 0.75% and the Eurodollar rate loans to 1.75%, in each case, based on the leverage ratio of the company. It also increases the highest applicable facility fee to 0.50%, due quarterly on all commitments under the credit facility. Previously, on April 21, 2015, the company amended the credit facility to extend the term to April 21, 2020, reduce the applicable margin on base rate and Eurodollar loans and reduce the facility fees, described below. The April 21, 2015 amendment was accounted for as a modification of the debt. The credit facility is a five-year, $500.0 million senior unsecured revolving loan facility. The credit facility contains a provision that permits us to request up to $200.0 million in additional revolving commitments, for a total of up to $700.0 million, subject to the satisfaction of certain conditions. Proceeds from the credit facility may be used for working capital and general corporate purposes, including capital expenditures, acquisition financing, refinancing of indebtedness, dividends and share repurchases. The credit facility includes certain customary restrictions, which, among other things, require maintenance of financial covenants and limit encumbrance of assets and creation of indebtedness. Restrictive financial covenants include such ratios as a minimum interest coverage ratio (4.50 times computed interest expense) and a maximum leverage ratio (3.75 times computed earnings). As of July 15, 2017 and December 31, 2016, respectively, the company was in compliance with all restrictive covenants under the credit facility. Interest is due either monthly or quarterly in arrears on any outstanding borrowings at a customary Eurodollar rate or the base rate plus applicable margin, respectively. The underlying rate is defined as rates offered in the interbank Eurodollar market, or the higher of the prime lending rate or the federal funds rate plus 0.50%, with a floor rate defined by the one-month interbank Eurodollar market rate plus 1.00%. The applicable margin ranges from 0.0% to 0.75% for base rate loans and from 0.70% to 1.75% for Eurodollar loans. In addition, a facility fee ranging from 0.05% to 0.50% is due quarterly on all commitments under the credit facility. Both the interest margin and the facility fee are based on the company’s leverage ratio. Financing costs paid at inception of the credit facility and at the time amendments are executed are being amortized over the life of the credit facility. The balance of unamortized financing costs was $0.9 million and $1.1 million on July 15, 2017 and December 31, 2016, respectively, and are recorded in other assets on the Condensed Consolidated Balance Sheets. Amounts outstanding under the credit facility vary daily. Changes in the gross borrowings and repayments can be caused by cash flow activity from operations, capital expenditures, acquisitions, dividends, share repurchases, and tax payments, as well as derivative transactions, which are part of the company’s overall risk management strategy as discussed in Note 8, Derivative Financial Instruments Amount (thousands) Balance at December 31, 2016 $ 24,000 Borrowings 347,900 Payments (368,500 ) Balance at July 15, 2017 $ 3,400 The table below presents the net amount available under the credit facility as of July 15, 2017: Amount (thousands) Gross amount available $ 500,000 Outstanding (3,400 ) Letters of credit (8,698 ) Available for withdrawal $ 487,902 The table below presents the highest and lowest outstanding balance under the credit facility during the twenty-eight weeks ended July 15, 2017: Amount (thousands) High balance $ 47,500 Low balance $ — Aggregate maturities of debt outstanding, including capital leases and the associated interest, as of July 15, 2017, are as follows (excluding unamortized debt discount and issuance costs) (amounts in thousands): Remainder of 2017 $ 5,196 2018 21,794 2019 10,314 2020 8,428 2021 3,276 2022 and thereafter 806,025 Total $ 855,033 Debt discount and issuance costs are being amortized straight-line (which approximates the effective method) over the term of the underlying debt outstanding.

During the twenty-eight weeks ended July 15, 2017, the company terminated certain operating lease contracts prior to the maturity date, which resulted in net termination costs. The net termination costs consisted of $1.2 million of lease termination gain recognized in the selling, distribution and administrative line item and $1.8 million of lease termination costs recognized in the depreciation and amortization line item of our Condensed Consolidated Statements of Income.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Variable Interest Entities	10. VARIABLE INTEREST ENTITIES Transportation agreement variable interest entity (the “VIE”) analysis The company maintains a transportation agreement with an entity that transports a significant portion of the company’s fresh bakery products from the company’s production facilities to outlying distribution centers. The company represents a significant portion of the entity’s revenue. This entity qualifies as a VIE, but the company has determined it is not the primary beneficiary of the VIE because the company does not (i) have the ability to direct the significant activities of the VIE that would affect its ability to operate its business and (ii) provide the VIE any implicit or explicit guarantees or other financial support to the VIE for specific return or performance benchmarks. In addition, we do not, nor do we intend to, provide financial or other support to the VIE. The company has concluded that certain of the trucks and trailers used by the VIE to distribute our products from the production facilities to outlying distribution centers qualify as right to use leases. As of July 15, 2017 and December 31, 2016, there was $26.6 million and $30.4 million, respectively, in net property, plant and equipment and capital lease obligations associated with the right to use leases. Distribution rights agreement VIE analysis The incorporated independent distributors (“IDs”) in the DSD Segment qualify as VIEs. The independent distributors who are formed as sole proprietorships are excluded from the following VIE accounting analysis and discussion. IDs acquire distribution rights and enter into a contract with the company to sell the company’s products in the IDs’ defined geographic territory. The IDs have the option to finance the acquisition of their distribution rights with the company. They can also pay cash or obtain external financing at the time they acquire the distribution rights. The combination of the company’s loans to the IDs and the ongoing distributor arrangements with the IDs provide a level of funding to the equity owners of the various IDs that would not otherwise be available. As of July 15, 2017 and December 31, 2016, there was $110.6 million and $84.3 million, respectively, in gross distribution rights notes receivable outstanding for IDs. The company is not considered to be the primary beneficiary of the VIEs because the company does not (i) have the ability to direct the significant activities of the VIEs that would affect their ability to operate their respective businesses and (ii) provide any implicit or explicit guarantees or other financial support to the VIEs, other than the financing described above, for specific return or performance benchmarks. The activities controlled by the IDs that are deemed to most significantly impact the ultimate success of the ID entities relate to those decisions inherent in operating the distribution business in the territory, including acquiring trucks and trailers, managing fuel costs, employee matters and other strategic decisions. In addition, we do not, nor do we intend to, provide financial or other support to the IDs. The IDs are responsible for the operations of their respective territories. The company’s maximum contractual exposure to loss for the IDs relates to the distribution rights note receivable for the portion of the territory the IDs financed at the time they acquired the distribution rights. The IDs remit payment on their distribution rights note receivable each week during the settlement process of their weekly activity. The company will operate a territory on behalf of an ID in situations where the ID has abandoned its distribution rights. Any remaining balance outstanding on the distribution rights note receivable is relieved once the distribution rights have been sold on the IDs behalf. The company’s collateral from the territory distribution rights mitigates potential losses.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. COMMITMENTS AND CONTINGENCIES Self-insurance reserves and other commitments and contingencies The company has recorded current liabilities of $37.1 million and $28.0 million related to self-insurance reserves, excluding the distributor litigation discussed below, at July 15, 2017 and December 31, 2016, respectively. The reserves include an estimate of expected settlements on pending claims, defense costs and a provision for claims incurred but not reported. These estimates are based on the company’s assessment of potential liability using an analysis of available information with respect to pending claims, historical experience and current cost trends. The amount of the company’s ultimate liability in respect of these matters may differ materially from these estimates. In the event the company ceases to utilize the independent distribution model of doing business or exits a geographic market, the company is contractually required to purchase the distribution rights from the independent distributor. The company expects to continue operating under this model and the possibility of a loss is remote. The company’s facilities are subject to various federal, state and local laws and regulations regarding the discharge of material into the environment and the protection of the environment in other ways. The company is not a party to any material proceedings arising under these laws and regulations. The company believes that compliance with existing environmental laws and regulations will not materially affect the consolidated financial condition, results of operations, cash flows or the competitive position of the company. The company believes it is currently in substantial compliance with all material environmental laws and regulations affecting the company and its properties. On August 9, 2016, the U.S. Department of Labor (the “DOL”) notified the company that it was scheduled for a compliance review under the Fair Labor Standards Act (“FLSA”). The company is cooperating with the DOL. Litigation The company and its subsidiaries from time to time are parties to, or targets of, lawsuits, claims, investigations and proceedings, including personal injury, commercial, contract, environmental, antitrust, product liability, health and safety and employment matters, which are being handled and defended in the ordinary course of business. While the company is unable to predict the outcome of these matters, it believes, based upon currently available facts, that it is remote that the ultimate resolution of any such pending matters will have a material adverse effect on its consolidated financial condition, results of operations or cash flows in the future. However, adverse developments could negatively impact earnings in a particular future fiscal period. At this time, the company is defending 30 complaints filed by distributors alleging that such distributors were misclassified as independent contractors. Twenty-one of these lawsuits seek class and/or collective action treatment. The remaining nine cases either allege individual claims or do not seek class or collective action treatment or, in cases in which class treatment was sought, the court denied class certification. The respective courts have ruled on plaintiffs’ motions for class certification in 13 of the pending cases, each of which is discussed below and in each case where a class has been conditionally certified under the FLSA, the company has the ability to petition the court to decertify that class at a later date Case Status Martinez et al. v.

Plaintiffs also allege in their complaint a New Mexico state law wage claim. The company and/or its respective subsidiaries are vigorously defending all of these lawsuits. Given the stage of the complaints and the claims and issues presented, except for lawsuits disclosed herein that have reached a settlement or agreement in principle, a loss is reasonably possible but the company cannot reasonably estimate at this time the possible loss or range of loss that may arise from the unresolved lawsuits. On December 9, 2016, Flowers Foods and Flowers Baking Co. of Jamestown, LLC reached an agreement to settle a lawsuit that asserted claims under the FLSA and a North Carolina state wage law which had been certified as a collective and class action ( Rehberg et al. v. Flowers Foods, Inc. and Flowers Baking Co. of Jamestown, LLC On November 8, 2016, Flowers Foods' subsidiary, Lepage Bakeries, reached an agreement to settle a lawsuit seeking class action treatment ( Bokanoski et al. v. Lepage Bakeries Park Street, LLC and CK Sales Co., LLC On February 28, 2017, Flowers Foods and Flowers Baking Co. of Batesville, LLC reached an agreement to settle a lawsuit that had been conditionally certified as a collective action under the FLSA ( Stewart v. Flowers Foods, Inc. and Flowers Baking Co. of Batesville, LLC .S. District Court for the Western District of Tennessee, for $250,000, including attorneys’ fees On August 12, 2016, a class action complaint was filed in the U.S. District Court for the Southern District of New York by Chris B. Hendley (the “Hendley complaint”) against the company and certain senior members of management (collectively, the “defendants”). On August 17, 2016, another class action complaint was filed in the U.S. District Court for the Southern District of New York by Scott Dovell, II (the “Dovell complaint” and together with the Hendley complaint, the “complaints”) against the defendants. Plaintiffs in the complaints are securities holders that acquired company securities between February 7, 2013 and August 10, 2016. The complaints generally allege that the defendants made materially false and/or misleading statements and/or failed to disclose that (1) the company’s labor practices were not in compliance with applicable federal laws and regulations; (2) such non-compliance exposed the company to legal liability and/or negative regulatory action; and (3) as a result, the defendants’ statements about the company’s business, operations, and prospects were false and misleading and/or lacked a reasonable basis. The counts of the complaints are asserted against the defendants pursuant to Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 under the Exchange Act. The complaints seek (1) class certification under the Federal Rules of Civil Procedure, (2) compensatory damages in favor of the plaintiffs and all other class members against the defendants, jointly and severally, for all damages sustained as a result of wrongdoing, in an amount to be proven at trial, including interest, and (3) awarding plaintiffs and the class their reasonable costs and expenses incurred in the actions, including counsel and expert fees. On October 21, 2016, the U.S. District Court for the Southern District of New York consolidated the complaints into one action captioned “In re Flowers Foods, Inc. Securities Litigation” (the “consolidated action”), appointed Walter Matthews as lead plaintiff (“lead plaintiff”), and appointed Glancy Prongay & Murray LLP and Johnson & Weaver, LLP as co-lead counsel for the putative class. On November 21, 2016, the court granted defendants’ and lead plaintiff’s joint motion to transfer the consolidated action to the U.S. District Court for the Middle District of Georgia. Lead plaintiff filed his Consolidated Class Action Complaint (“Complaint”) on January 12, 2017, raising the same counts and general allegations and seeking the same relief as the Dovell and Hendley complaints. On March 13, 2017, the company filed a motion to dismiss the lawsuit which remains pending before the court at this time. The company and/or its respective subsidiaries are vigorously defending these lawsuits. Given the stage of the complaints and the claims and issues presented, the company cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from the unresolved lawsuits.

Stock-Based Compensation	13. STOCK-BASED COMPENSATION On March 5, 2014, our Board of Directors approved and adopted the 2014 Omnibus Equity and Incentive Compensation Plan (“Omnibus Plan”). The Omnibus Plan was approved by our shareholders on May 21, 2014. The Omnibus Plan authorizes the compensation committee of the Board of Directors to provide equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, dividend equivalents and other awards for the purpose of providing our officers, key employees, and non-employee directors’ incentives and rewards for performance. The Omnibus Plan replaced the Flowers Foods’ 2001 Equity and Performance Incentive Plan, as amended and restated as of April 1, 2009 (“EPIP”), the stock appreciation right plan, and the bonus plan. All outstanding equity awards that were made under the EPIP will continue to be governed by the EPIP; however, all equity awards granted after May 21, 2014 are governed by the Omnibus Plan. No additional awards will be issued under the EPIP. Awards granted under the Omnibus Plan are limited to the authorized amount of 8,000,000 shares. The EPIP authorized the compensation committee of the Board of Directors to make awards of options to purchase our common stock, restricted stock, performance stock and units and deferred stock. The company’s officers, key employees and non-employee directors (whose grants are generally approved by the full Board of Directors) were eligible to receive awards under the EPIP. Over the life of the EPIP, the company issued stock options, restricted stock and deferred stock. The following is a summary of stock options, restricted stock, and deferred stock outstanding under the plans described above. Information relating to the company’s stock appreciation rights, which were issued under a separate stock appreciation right plan, is also described below. Stock Options The company issued non-qualified stock options (“NQSOs”) during fiscal years 2011 and prior that have no additional service period remaining. All outstanding NQSOs have vested and are exercisable on July 15, 2017. The stock option activity for the twenty-eight weeks ended July 15, 2017 pursuant to the EPIP is set forth below (amounts in thousands, except price data): Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2016 1,846 $ 10.89 Exercised (587 ) $ 10.93 Outstanding at July 15, 2017 1,259 $ 10.87 0.57 $ 8,411 Exercisable at July 15, 2017 1,259 $ 10.87 0.57 $ 8,411 As of July 15, 2017, compensation expense related to the NQSOs was fully amortized. The cash received, the windfall tax benefit, and intrinsic value from stock option exercises for the twenty-eight weeks ended July 15, 2017 and July 16, 2016, respectively, were as follows (amounts in thousands): July 15, 2017 July 16, 2016 Cash received from option exercises $ 6,416 $ 10,478 Tax benefit at exercise, net $ 1,477 $ 2,020 Intrinsic value of stock options exercised $ 5,215 $ 7,500 Performance-Contingent Restricted Stock Awards Performance-Contingent Total Shareholder Return Shares (“TSR Shares”) Certain key employees have been granted performance-contingent restricted stock under the Omnibus Plan in the form of TSR Shares. The awards vest approximately two years from the date of grant (after the filing of the company’s Annual Report on Form 10-K), and the shares become non-forfeitable if, and to the extent that, on that date the vesting conditions are satisfied. The total shareholder return (“TSR”) is the percent change in the company’s stock price over the measurement period plus the dividends paid to shareholders. The performance payout is calculated at the end of each of the last four quarters (averaged) in the measurement period. Once the TSR is determined for the company (“Company TSR”), it is compared to the TSR of our food company peers (“Peer Group TSR”). The Company TSR compared to the Peer Group TSR will determine the payout as set forth below: Percentile Payout as % of Target 90th 200 % 70th 150 % 50th 100 % 30th 50 % Below 30th 0 % For performance between the levels described above, the degree of vesting is interpolated on a linear basis. The 2015 award, which vested in fiscal 2017, did not meet the performance condition and no shares were issued. The 2014 award, which vested in fiscal 2016, vested at 27% of target. The TSR shares vest immediately if the grantee dies or becomes disabled. However, if the grantee retires at age 65 (or age 55 with at least 10 years of service with the company) or later, on the normal vesting date the grantee will receive a pro-rated number of shares based upon the retirement date and measured at the actual performance for the entire performance period. In addition, if the company undergoes a change in control, the TSR shares will immediately vest at the target level, provided that if 12 months of the performance period have been completed, vesting will be determined based on Company TSR as of the date of the change in control without application of four-quarter averaging. During the vesting period, the grantee has none of the rights of a shareholder. Dividends declared during the vesting period will accrue and will be paid at vesting on the TSR shares that ultimately vest. The fair value estimate was determined using a Monte Carlo The following performance-contingent TSR Shares have been granted under the Omnibus Plan and have service period remaining (amounts in thousands, except price data): Grant date January 1, 2017 January 3, 2016 Shares granted 426 401 Vesting date 3/1/2019 2/21/2018 Fair value per share $ 23.31 $ 24.17 Performance-Contingent Return on Invested Capital Shares (“ROIC Shares”) Certain key employees have been granted performance-contingent restricted stock under the Omnibus Plan in the form of ROIC Shares. The awards generally vest approximately two years from the date of grant (after the filing of the company’s Annual Report on Form 10-K), and the shares become non-forfeitable if, and to the extent that, on that date, the vesting conditions are satisfied. Return on Invested Capital (“ROIC”) is calculated by dividing our profit, as defined, by the invested capital. Generally, the performance condition requires the company’s average ROIC to exceed its average weighted cost of capital (“WACC”) by between 1.75 to 4.75 percentage points (the “ROI Target”) over the two fiscal year performance period. If the lowest ROI Target is not met, the awards are forfeited. The ROIC shares can be earned based on a range from 0% to 125% of target as defined below: • ROIC above WACC by less than 1.75 percentage points pays 0% of ROI Target; • ROIC above WACC by 1.75 percentage points pays 50% of ROI Target; or • ROIC above WACC by 3.75 percentage points pays 100% of ROI Target; or • ROIC above WACC by 4.75 percentage points pays 125% of ROI Target. For performance between the levels described above, the degree of vesting is interpolated on a linear basis. The 2015 award, which vested in fiscal 2017, actual attainment was 87% of ROI Target. The 2014 award, which vested in fiscal 2016, actual attainment was 96% of ROI Target. The ROIC Shares vest immediately if the grantee dies or becomes disabled. However, if the grantee retires at age 65 (or age 55 with at least 10 years of service with the company) or later, on the normal vesting date the grantee will receive a pro-rated number of ROIC shares based upon the retirement date and actual performance for the entire performance period. In addition, if the company undergoes a change in control, the ROIC Shares will immediately vest at the target level. During the vesting period, the grantee has none of the rights of a shareholder. Dividends declared during the vesting period will accrue and will be paid at vesting on the ROIC shares that ultimately vest. The fair value of this type of award is equal to the stock price on the grant date. Since these awards have a performance condition feature the expense associated with these awards may change depending on the expected ROI Target attained at each reporting period. The 2016 and 2017 awards are being expensed at 75% and 100% of ROI Target, respectively. The following performance-contingent ROIC Shares have been granted under the Omnibus Plan and have service period remaining (amounts in thousands, except price data): Grant date January 1, 2017 January 3, 2016 Shares granted 426 401 Vesting date 3/1/2019 2/21/2018 Fair value per share $ 19.97 $ 21.49 Performance-Contingent Restricted Stock Summary The table below presents the TSR modifier share adjustment, ROIC modifier share adjustment, accumulated dividends on vested shares, and the tax benefit/(expense) at vesting of the performance-contingent restricted stock awards (amounts in thousands, except per share data). The shortfall at vesting of 2015 award was recorded as tax expense. The tax impact on the 2014 award at vesting was treated as a shortfall for reporting purposes. Award granted Fiscal year vested TSR modifier increase/(decrease) shares ROIC modifier increase/(decrease) shares Dividends at vesting (thousands) Tax benefit/(expense) Fair value at vesting 2015 2017 (378,219 ) (49,272 ) $ 392 $ (3,099 ) $ 6,316 2014 2016 (248,872 ) (13,637 ) $ 441 $ (3,090 ) $ 7,173 Performance-Contingent Restricted Stock The company’s performance-contingent restricted stock activity for the twenty-eight weeks ended July 15, 2017 is presented below (amounts in thousands, except price data): Shares Weighted Average Grant Date Fair Value Nonvested shares at December 31, 2016 1,543 $ 21.53 Initial grant at target 855 $ 21.64 Grant reduction for not achieving the ROIC modifier (49 ) $ 19.14 Grant reduction for not achieving the TSR modifier (378 ) $ 21.21 Vested (329 ) $ 19.14 Forfeited (18 ) $ 21.02 Nonvested shares at July 15, 2017 1,624 $ 22.21 As of July 15, 2017, there was $18.1 million of total unrecognized compensation cost related to nonvested restricted stock granted under the Omnibus Plan. That cost is expected to be recognized over a weighted-average period of 1.38 years. The total intrinsic value of shares vested during the twelve and twenty-eight weeks ended July 15, 2017 was $6.3 million. Deferred and Restricted Stock Non-employee directors may convert their annual board retainers into deferred stock equal in value to 100% of the cash payments directors would otherwise receive and the vesting period is a one-year period to match the period of time that cash would have been received if no conversion existed. Accumulated dividends are paid upon delivery of the shares. During fiscal 2017, non-employee directors elected to receive an aggregate of 10,020 common shares for board retainer deferrals pursuant to the Omnibus Plan. Non-employee directors also receive annual grants of deferred stock. This deferred stock vests one year from the grant date. The deferred stock will be distributed to the grantee at a time designated by the grantee at the date of grant. Compensation expense is recorded on this deferred stock over the one-year minimum vesting period. During fiscal 2017, non-employee directors received an aggregate of 77,220 shares for their annual grant pursuant to the Omnibus Plan. On May 31, 2013, the company’s Chief Executive Officer (“CEO”) received a time-based restricted stock award of approximately $1.3 million of restricted stock pursuant to the EPIP. This award vested at 100% on the fourth anniversary of the date of the grant. Dividends accrued on the award and were paid to the CEO on the vesting date. There were 58,500 shares issued for this award at a fair value of $22.25 per share. This award vested at a price of $18.48 and the shares were issued in our second quarter of fiscal 2017. The deferred stock activity for the twenty-eight weeks ended July 15, 2017 is set forth below (amounts in thousands, except price data): Shares Weighted Average Fair Value Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Nonvested shares at December 31, 2016 149 $ 20.39 Vested (149 ) $ 20.39 Granted 87 $ 18.70 Nonvested shares at July 15, 2017 87 $ 18.70 0.83 $ 1,531,062 As of July 15, 2017, there was $1.3 million of total unrecognized compensation cost related to deferred stock awards granted under the Omnibus Plan that will be recognized over a weighted-average period of 0.83 years. The total intrinsic value of shares vested during the twelve and twenty-eight weeks ended July 15, 2017 was $2.8 million.

Post-Retirement Plans	14. POST-RETIREMENT PLANS The following summarizes the company’s balance sheet related pension and other post-retirement benefit plan accounts at July 15, 2017 as compared to accounts at December 31, 2016 (amounts in thousands): July 15, 2017 December 31, 2016 Current benefit liability $ 979 $ 979 Noncurrent benefit liability $ 63,220 $ 69,601 Accumulated other comprehensive loss, net of tax $ 80,221 $ 82,222 Defined Benefit Plans and Nonqualified Plan The company amended our qualified defined benefit plans in October 2015 to allow pension plan participants not yet receiving benefit payments the option to elect to receive their benefit as a single lump sum payment. This amendment was effective as of January 1, 2016. This change supports our long-term pension risk management strategy. Settlement accounting, which accelerates recognition of a plan’s unrecognized net gain or loss, is triggered if the lump sums paid during a year exceeds the sum of the plan’s service and interest cost. We believe it is reasonably possible that we may have a settlement charge in future quarters during fiscal 2017. As of July 15, 2017, we have not met the settlement accounting threshold. The company used a measurement date of December 31, 2016 for the defined benefit and post-retirement benefit plans described below. The net periodic pension cost (income) for the company’s plans include the following components (amounts in thousands): For the Twelve Weeks Ended For the Twenty-Eight Weeks Ended July 15, 2017 July 16, 2016 July 15, 2017 July 16, 2016 Service cost $ 174 $ 192 $ 407 $ 447 Interest cost 3,006 2,884 7,013 7,417 Expected return on plan assets (5,895 ) (5,457 ) (13,754 ) (14,069 ) Settlement loss — 4,641 — 4,641 Amortization of prior service cost 89 76 208 195 Amortization of net loss 1,469 1,155 3,427 2,953 Total net periodic pension benefit (income) cost $ (1,157 ) $ 3,491 $ (2,699 ) $ 1,584 Post-retirement Benefit Plan The company provides certain medical and life insurance benefits for eligible retired employees covered under the active medical plans.

During the twelve weeks ended July 15, 2017 and July 16, 2016, the total cost and employer contributions were $6.6 million and $6.5 million, respectively. During the twenty-eight weeks ended July 15, 2017 and July 16, 2016, the total cost and employer contributions were $15.6 million and $14.8 million, respectively. The company acquired Dave’s Killer Bread and Alpine Valley Bread Company during fiscal 2015, at the time of each acquisition we assumed sponsorship of a 401(k) savings plan. We merged these two plans into the Flowers Foods, Inc. 401(k) Retirement Savings Plan on April 1, 2016.

Segment Reporting	16. SEGMENT REPORTING The company currently operates two business segments: the DSD Segment and the Warehouse Segment. The DSD Segment produces a wide variety of fresh bakery foods, including fresh breads, buns, rolls, tortillas, and snack cakes, which are sold through a DSD route delivery system to retail and foodservice customers in the East, South, Southwest, California, and select markets in the Midwest, Pacific Northwest, Nevada and Colorado. The Warehouse Segment produces snack cakes, breads and rolls for national retail, foodservice, vending, and co-pack customers and delivers through customers’ warehouse channels. The company evaluates each segment’s performance based on income or loss before interest and income taxes, excluding unallocated expenses and charges, which the company’s management deems to be an overall corporate cost or a cost not reflective of the segment’s core operating businesses.

Property Plant And Equipment Assets Held For Sale Disclosure [Abstract]
Assets Held for Sale	17. ASSETS HELD FOR SALE The company purchases distribution rights from and sells distribution rights to independent distributors from time to time. The company repurchases distribution rights from independent distributors in circumstances when the company decides to exit a territory or, in some cases, when the independent distributor elects to terminate its relationship with the company. In the majority of the distributor agreements, if the company decides to exit a territory or stop using the independent distribution model in a territory, the company is contractually required to purchase the distribution rights from the independent distributor. In the event an independent distributor terminates its relationship with the company, the company, although not legally obligated, may repurchase and operate those distribution rights as a company-owned territory. The independent distributors may also sell their distribution rights to another person or entity. Distribution rights purchased from independent distributors and operated as company-owned territories are recorded on the Condensed Consolidated Balance Sheets in the line item “Assets held for sale” while the company actively seeks another independent distributor to purchase the distribution rights for the territory. Distributions rights held for sale and operated by the company are sold to independent distributors at fair market value pursuant to the terms of a distributor agreement. There are multiple versions of the distributor agreement in place at any given time and the terms of such distributor agreements vary. Additional assets recorded in assets held for sale are for property, plant and equipment. The carrying values of assets held for sale are not amortized and are evaluated for impairment as required at the end of the reporting period. The table below presents the assets held for sale as of July 15, 2017 and December 31, 2016, respectively (amounts in thousands): July 15, 2017 December 31, 2016 Distributor territories $ 24,745 $ 31,897 Property, plant and equipment 1,283 5,079 Total assets held for sale $ 26,028 $ 36,976

Subsequent Events [Abstract]
Subsequent Events	18. SUBSEQUENT EVENTS The company has evaluated subsequent events since July 15, 2017, the date of these financial statements. We believe there were no material events or transactions discovered during this evaluation that require recognition or disclosure in the financial statements other than the items discussed below. On July 17, 2017, the company commenced a voluntary employee separation incentive plan (the “VSIP”) as part of its effort to restructure, streamline operations and better position the company for profitable growth. The VSIP is available to certain employees who meet the VSIP’s age, length-of-service and business function criteria. Employees who elect to participate in the VSIP will receive enhanced separation benefits. The VSIP is expected to be substantially completed by the end of fiscal 2017. The company currently does not know which employees will elect to participate in the VSIP. Accordingly, the company is unable to estimate the costs of the VSIP, which will consist primarily of employee severance and benefits-related costs. The company will provide an estimate of the amount or range of costs and benefits when a good faith determination can be made, which is expected to be in the third quarter of 2017. On August 9, 2017, the company announced the closure of a warehouse delivery snack cake plant in Winston-Salem, North Carolina. We expect to close the bakery in early October 2017. The closure costs are estimated to be between $4.0 million and $6.0 million and are expected to be finalized and recorded in our third quarter of fiscal 2017.

Estimates	ESTIMATES — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The company believes the following critical accounting estimates affect its more significant judgments and estimates used in the preparation of its consolidated financial statements: revenue recognition, derivative instruments, valuation of long-lived assets, goodwill and other intangible assets, self-insurance reserves, income tax expense and accruals, pension obligations, stock-based compensation, and commitments and contingencies. These estimates are summarized in the Form 10-K.
Reporting Periods	REPORTING PERIODS — The company operates on a 52-53 week fiscal year ending the Saturday nearest December 31. Fiscal 2017 consists of 52 weeks, with the company’s quarterly reporting periods as follows: first quarter ended April 22, 2017 (sixteen weeks), second quarter ended July 15, 2017 (twelve weeks), third quarter ending October 7, 2017 (twelve weeks) and fourth quarter ending December 30, 2017 (twelve weeks).
Segments	SEGMENTS — Flowers Foods currently operates two business segments: a direct-store-delivery (“DSD”) segment (“DSD Segment”) and a warehouse delivery segment (“Warehouse Segment”). The DSD Segment (85% of total year to date sales) currently operates 39 plants that produce a wide variety of fresh bakery foods, including fresh breads, buns, rolls, tortillas, and snack cakes. These products are sold through a DSD route delivery system to retail and foodservice customers in the East, South, Southwest, California, and select markets in the Midwest, Pacific Northwest, Nevada, and Colorado. The Warehouse Segment (15% of total year to date sales) currently operates ten plants that produce snack cakes, breads and rolls for national retail, foodservice, vending, and co-pack customers and deliver through customers’ warehouse channels. On May 3, 2017, the company announced an enhanced organizational structure designed to provide greater focus on the company’s strategic objectives, emphasize brand growth and innovation in line with a national branded food company, drive enhanced accountability, reduce costs, and strengthen long-term strategy. The new organizational structure establishes two business units (“BUs”), Fresh Bakery and Specialty/Snacking, and realigns key leadership roles. The new structure also provides for centralized marketing, sales, supply chain, shared-services/administrative, and corporate strategy functions, each with clearly defined roles and responsibilities. The company intends to transition to the new structure over the next several months with full implementation expected during fiscal 2018. The current DSD and warehouse segmentation will remain until the new structure is in place.
