Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies (a) Business Publix Super Markets, Inc. and its wholly owned subsidiaries (the Company) are in the business of operating retail food supermarkets in Florida, Georgia, Alabama, South Carolina, Tennessee and North Carolina. The Company plans to expand its retail operations into Virginia in 2017. The Company was founded in 1930 and later merged into another corporation that was originally incorporated in 1921. The Company has no other significant lines of business or industry segments. See percentage of consolidated sales by merchandise category on page 1. (b) Principles of Consolidation The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and certain joint ventures in which the Company has a controlling financial interest. All significant intercompany balances and transactions are eliminated in consolidation. (c) Fiscal Year The Company’s fiscal year ends on the last Saturday in December. Fiscal year 2016 includes 53 weeks and fiscal years 2015 and 2014 include 52 weeks. (d) Cash Equivalents The Company considers all liquid investments with maturities of three months or less to be cash equivalents. (e) Trade Receivables Trade receivables primarily include amounts due from vendor allowances, debit and credit card sales and third party insurance pharmacy billings. (f) Inventories Inventories are valued at the lower of cost or market. The cost for 83% and 84% of inventories was determined using the dollar value last-in, first-out (LIFO) method as of December 31, 2016 and December 26, 2015 , respectively. Under this method, inventory is stated at cost, which is determined by applying a cost-to-retail ratio to each similar merchandise category’s ending retail value. The cost of the remaining inventories was determined using the first-in, first-out (FIFO) method. The FIFO cost of inventory approximates replacement or current cost. The FIFO method is used to value manufactured, seasonal, certain perishable and other miscellaneous inventory items because of fluctuating costs and inconsistent product availability. The Company also reduces inventory for estimated losses related to shrink. If all inventories were valued using the FIFO method, inventories and current assets would have been higher than reported by $441,860,000 and $446,503,000 as of December 31, 2016 and December 26, 2015 , respectively. (g) Investments Debt and equity securities are classified as available-for-sale (AFS) and carried at fair value. The Company evaluates whether AFS securities are other-than-temporarily impaired (OTTI) based on criteria that include the extent to which cost exceeds market value, the duration of the market value decline, the credit rating of the issuer or security, the failure of the issuer to make scheduled principal or interest payments and the financial health and prospects of the issuer or security. Declines in the value of AFS securities determined to be OTTI are recognized in earnings and reported as OTTI losses. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the debt security or if the Company will be required to sell the debt security prior to any anticipated recovery. If the Company determines that a debt security is OTTI under these circumstances, the impairment recognized in earnings is measured as the difference between the amortized cost and the current fair value. A debt security is also determined to be OTTI if the Company does not expect to recover the amortized cost of the debt security. However, in this circumstance, if the Company does not intend to sell the debt security and will not be required to sell the debt security, the impairment recognized in earnings equals the estimated credit loss as measured by the difference between the present value of expected cash flows and the amortized cost of the debt security. Expected cash flows are discounted using the debt security’s effective interest rate. An equity security is determined to be OTTI if the Company does not expect to recover the cost of the equity security. Declines in the value of AFS securities determined to be temporary are reported net of income taxes as other comprehensive losses and included as a component of stockholders’ equity. Interest and dividend income, amortization of premiums, accretion of discounts and realized gains and losses on AFS securities are included in investment income. Interest income is accrued as earned. Dividend income is recognized as income on the ex-dividend date of the security. The cost of AFS securities sold is based on the FIFO method. (h) Property, Plant and Equipment and Depreciation Assets are recorded at cost and are depreciated using the straight-line method over their estimated useful lives or the terms of the related leases, if shorter, as follows: Buildings and improvements 10–40 years Furniture, fixtures and equipment 3–20 years Leasehold improvements 10–20 years Maintenance and repairs are charged to operating expenses as incurred. Expenditures for renewals and betterments are capitalized. The gain or loss realized on disposed assets or assets to be disposed of is recorded as operating and administrative expenses in the consolidated statements of earnings. (i) Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the net book value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the net book value of an asset to the future net undiscounted cash flows expected to be generated by the asset. An impairment loss is recorded for the excess of the net book value over the fair value of the asset. The fair value is estimated based on expected discounted future cash flows. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell and are no longer depreciated. Long-lived assets, including buildings and improvements, leasehold improvements, and furniture, fixtures and equipment, are evaluated for impairment at the supermarket level. (j) Self-Insurance The Company is self-insured for health care claims and property, plant and equipment losses. The Company has insurance coverage for losses in excess of self-insurance limits for workers’ compensation, general liability and fleet liability claims. Self-insurance reserves are established for health care, workers’ compensation, general liability and fleet liability claims. These reserves are determined based on actual claims experience and an estimate of claims incurred but not reported including, where necessary, actuarial studies. Actuarial projections of losses for general liability and workers’ compensation claims are discounted. (k) Postretirement Benefit The Company provides a postretirement life insurance benefit for certain salaried and hourly full-time employees who meet the eligibility requirements. Effective January 1, 2002, the Company amended the postretirement life insurance benefit under its Group Life Insurance Plan. To receive the postretirement life insurance benefit after the amendment, an employee must have had at least five years of full-time service and the employee’s age plus years of credited service must have equaled 65 or greater as of October 1, 2001. At retirement, such employees also must be at least age 55 with at least 10 years of full-time service to be eligible to receive the postretirement life insurance benefit. Actuarial projections are used to calculate the year end postretirement benefit obligation, discounted using a yield curve methodology based on high quality bonds with a rating of AA or better. Actuarial losses are amortized from accumulated other comprehensive earnings into net periodic postretirement benefit cost over future years when the accumulation of such losses exceeds 10% of the year end postretirement benefit obligation. (l) Comprehensive Earnings Comprehensive earnings include net earnings and other comprehensive earnings. Other comprehensive earnings include revenues, expenses, gains and losses that have been excluded from net earnings and recorded directly to stockholders’ equity. Included in other comprehensive earnings for the Company are unrealized gains and losses on AFS securities and adjustments to the postretirement benefit obligation. (m) Revenue Recognition Revenue is recognized at the point of sale for retail sales. Customer returns are immaterial. Vendor coupons that are reimbursed are accounted for as sales. Coupons and other sales incentives offered by the Company that are not reimbursed are recorded as a reduction of sales. (n) Sales Taxes The Company records sales net of applicable sales taxes. (o) Other Operating Income Other operating income is recognized on a net revenue basis as earned. Other operating income includes income generated from other activities, primarily lottery commissions, licensee sales commissions, automated teller transaction fees, mall gift card commissions, vending machine commissions, money transfer fees and coupon redemption income. (p) Cost of Merchandise Sold Cost of merchandise sold includes costs of inventory and costs related to in-store production. Cost of merchandise sold also includes inbound freight charges, purchasing and receiving costs, warehousing costs and other costs of the Company’s distribution network. Allowances and credits, including cooperative advertising allowances, received from a vendor in connection with the purchase or promotion of the vendor’s products are recognized as a reduction of cost of merchandise sold as earned. These allowances and credits are recognized as earned in accordance with the underlying agreement with the vendor and completion of the earnings process. Short-term vendor agreements with advance payment provisions are recorded as a current liability and recognized over the appropriate period as earned according to the underlying agreements. Long-term vendor agreements with advance payment provisions are recorded as a noncurrent liability and recognized over the appropriate period as earned according to the underlying agreements. (q) Advertising Costs Advertising costs are expensed as incurred and were $260,367,000 , $248,454,000 and $232,499,000 for 2016 , 2015 and 2014 , respectively. (r) Other Nonoperating Income, net Other nonoperating income, net includes rent received from tenants in owned shopping centers, net of related expenses, and other miscellaneous nonoperating income. (s) Income Taxes Deferred tax assets and liabilities are established for temporary differences between financial and tax reporting bases and are subsequently adjusted to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The Company recognizes accrued interest and penalties related to income tax liabilities as a component of income tax expense. The Company invests in certain investment related tax credits that promote affordable housing and renewable energy. These investments generate a return primarily through the realization of federal and state tax credits and other tax benefits. The Company accounts for its affordable housing investments using the proportional amortization method. Under this method, the investment is amortized into income tax expense in proportion to the tax credits received and the investment tax credits are recognized as a reduction of income tax expense. The Company accounts for its renewable energy investments using the deferral method. Under this method, the investment tax credits are recognized as a reduction of the renewable energy investments. (t) Common Stock and Earnings Per Share Basic and diluted earnings per share are calculated by dividing net earnings by the weighted average shares outstanding. Basic and diluted earnings per share are the same because the Company does not have options or other stock compensation programs that impact the calculation of diluted earnings per share. All shares owned by the Employee Stock Ownership Plan (ESOP) are included in the earnings per share calculations. Dividends paid to the ESOP, as well as dividends on all other common stock shares, are reflected as a reduction of retained earnings. All common stock shares, including ESOP and 401(k) Plan shares, receive one vote per share and have the same dividend rights. The voting rights for ESOP shares allocated to participants’ accounts are passed through to the participants. The Trustee of the Company’s common stock in the 401(k) Plan votes the shares held in that plan. (u) Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of 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.

Fair Value of Financial Instruments	(2) Fair Value of Financial Instruments The fair value of certain of the Company’s financial instruments, including cash and cash equivalents, trade receivables and accounts payable, approximates their respective carrying amounts due to their short-term maturity. The fair value of AFS securities is based on market prices using the following measurement categories: Level 1 – Fair value is determined by using quoted prices in active markets for identical investments. AFS securities that are included in this category are primarily mutual funds, exchange traded funds and equity securities. Level 2 – Fair value is determined by using other than quoted prices. By using observable inputs (for example, benchmark yields, interest rates, reported trades and broker dealer quotes), the fair value is determined through processes such as benchmark curves, benchmarking of like securities and matrix pricing of corporate, state and municipal bonds by using pricing of similar bonds based on coupons, ratings and maturities. AFS securities that are included in this category are primarily debt securities (tax exempt and taxable bonds). Level 3 – Fair value is determined by using other than observable inputs. Fair value is determined by using the best information available in the circumstances and requires significant management judgment or estimation. No AFS securities are currently included in this category. Following is a summary of fair value measurements for AFS securities as of December 31, 2016 and December 26, 2015 : Fair Value Level 1 Level 2 Level 3 (Amounts are in thousands) December 31, 2016 $ 6,738,618 1,286,625 5,451,993 — December 26, 2015 6,602,934 1,049,791 5,553,143 —

Unrealized losses related to debt securities are primarily due to interest rate volatility impacting the market value of certain bonds. The Company continues to receive scheduled principal and interest payments on these debt securities. Unrealized losses related to equity securities are primarily due to temporary equity market fluctuations that are expected to recover.

Consolidation Of Joint Ventures And Long Term Debt [Abstract]
Consolidation of Joint Ventures and Long-Term Debt	(4) Consolidation of Joint Ventures and Long-Term Debt From time to time, the Company enters into Joint Ventures (JV), in the legal form of limited liability companies, with certain real estate developers to partner in the development of shopping centers with the Company as the anchor tenant. The Company consolidates certain of these JVs in which it has a controlling financial interest. The Company is considered to have a controlling financial interest in a JV when it has (1) the power to direct the activities of the JV that most significantly impact the JV’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from the JV that could potentially be significant to such JV. The Company evaluates a JV using specific criteria to determine whether the Company has a controlling financial interest and is the primary beneficiary of the JV. Factors considered in determining whether the Company is the primary beneficiary include risk and reward sharing, experience and financial condition of the other JV members, voting rights, involvement in routine capital and operating decisions and each member’s influence over the JV owned shopping center’s economic performance. Generally, most major JV decision making is shared between all members. In particular, the use and sale of JV assets, business plans and budgets are generally required to be approved by all members. However, the Company, through its anchor tenant operating lease agreement, has the power to direct the activities that most significantly influence the economic performance of the JV owned shopping center. Additionally, through its member equity interest in the JV, the Company will receive a significant portion of the JV’s benefits or is obligated to absorb a significant portion of the JV’s losses. As of December 31, 2016 , the carrying amounts of the assets and liabilities of the consolidated JVs were $102,254,000 and $53,278,000 , respectively. As of December 26, 2015 , the carrying amounts of the assets and liabilities of the consolidated JVs were $141,355,000 and $64,928,000 , respectively. The assets are owned by and the liabilities are obligations of the JVs, not the Company, except for a portion of the long-term debt of certain JVs guaranteed by the Company. The JVs are financed with capital contributions from the members, loans and/or the cash flows generated by the JV owned shopping centers once in operation. Total earnings attributable to noncontrolling interests for 2016 , 2015 and 2014 were immaterial. The Company’s involvement with these JVs does not have a significant effect on the Company’s financial condition, results of operations or cash flows. The Company’s long-term debt results primarily from the consolidation of loans of certain JVs and loans assumed in connection with the acquisition of certain shopping centers with the Company as the anchor tenant. The Company assumed loans totaling $63,966,000 and $40,287,000 during 2016 and 2015 , respectively. Maturities of JV loans range from April 2017 through June 2017 and have variable interest rates based on a LIBOR index plus 175 to 250 basis points. Maturities of assumed shopping center loans range from March 2017 through January 2027 and have fixed interest rates ranging from 3.7% to 7.5% . As of December 31, 2016 , the aggregate annual maturities and scheduled payments of long-term debt are as follows: Year (Amounts are in thousands) 2017 $ 113,999 2018 37,873 2019 4,649 2020 19,150 2021 15,323 Thereafter 59,590 $ 250,584

Retirement Plans Disclosure [Abstract]
Retirement Plans	(5) Retirement Plans The Company has a trusteed, noncontributory ESOP for the benefit of eligible employees. The Company recognizes an expense related to the Company’s discretionary contribution to the ESOP based on a percent of net earnings before taxes that is approved by the Board of Directors each year. ESOP contributions can be made in Company common stock or cash. Compensation expense recorded for contributions to this plan was $334,422,000 , $337,703,000 and $310,050,000 for 2016 , 2015 and 2014 , respectively. Since the Company’s common stock is not traded on an established securities market, the ESOP includes a put option for shares of the Company’s common stock distributed from the ESOP. Shares are distributed from the ESOP primarily to separated vested participants and certain eligible participants who elect to diversify their account balances. Under the Company’s administration of the ESOP’s put option, if the owners of distributed shares desire to sell their shares, the Company is required to purchase the shares at fair value for a specified time period after distribution of the shares from the ESOP. The fair value of distributed shares subject to the put option totaled $425,514,000 and $427,226,000 as of December 31, 2016 and December 26, 2015 , respectively. The cost of the shares held by the ESOP totaled $2,642,583,000 and $2,526,652,000 as of December 31, 2016 and December 26, 2015 , respectively. Due to the Company’s obligation under the put option, the distributed shares subject to the put option and the shares held by the ESOP are classified as temporary equity in the mezzanine section of the consolidated balance sheets and totaled $3,068,097,000 and $2,953,878,000 as of December 31, 2016 and December 26, 2015 , respectively. The fair value of the shares held by the ESOP totaled $8,356,659,000 and $9,201,171,000 as of December 31, 2016 and December 26, 2015 , respectively. The Company has a 401(k) Plan for the benefit of eligible employees. The 401(k) Plan is a voluntary defined contribution plan. Eligible employees may contribute up to 10% of their eligible annual compensation, subject to the maximum contribution limits established by federal law. The Company may make a discretionary annual matching contribution to eligible participants of this plan as determined by the Board of Directors. During 2016 , 2015 and 2014 , the Board of Directors approved a match of 50% of eligible annual contributions up to 3% of annual compensation, not to exceed a maximum match of $750 per employee. The match, which is determined as of the last day of the plan year and paid in the subsequent plan year, is in common stock of the Company. Compensation expense recorded for the Company’s match to the 401(k) Plan was $30,899,000 , $30,775,000 and $28,475,000 for 2016 , 2015 and 2014 , respectively. The Company intends to continue its retirement plans; however, the right to modify, amend, terminate or merge these plans has been reserved. In the event of termination, all amounts contributed under the plans must be paid to the participants or their beneficiaries.

The Company has analyzed filing positions in all of the federal and state jurisdictions where it is required to file income tax returns as well as all open tax years in these jurisdictions. The periods subject to examination for the Company’s federal return are the 2010 through 2015 tax years. The periods subject to examination for the Company’s state returns are the 2011 through 2015 tax years. The Company believes that the outcome of any examination will not have a material effect on its financial condition, results of operations or cash flows. The Company had no unrecognized tax benefits in 2016 and 2015 . As a result, there will be no effect on the Company’s effective income tax rate in future periods due to the recognition of unrecognized tax benefits.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(8) Commitments and Contingencies (a) Operating Leases The Company conducts a major portion of its retail operations from leased premises. Initial terms of the leases are typically 20 years, followed by renewal options at five year intervals, and may include rent escalation clauses. Minimum rentals represent fixed lease obligations, including insurance and maintenance to the extent they are fixed in the lease. Contingent rentals represent variable lease obligations, including real estate taxes, insurance, maintenance and, for certain premises, additional rentals based on a percentage of sales in excess of stipulated minimums (excess rent). The payment of variable real estate taxes, insurance and maintenance is generally based on the Company’s pro-rata share of total shopping center square footage. The Company recognizes rent expense for operating leases with rent escalation clauses on a straight-line basis over the applicable lease term. The Company estimates excess rent, where applicable, based on annual sales projections and uses the straight-line method to amortize the cost to rent expense. The annual sales projections are reviewed periodically and adjusted if necessary. Additionally, the Company has operating leases for certain transportation and other equipment. Total rental expense for 2016 , 2015 and 2014 is as follows: 2016 2015 2014 (Amounts are in thousands) Minimum rentals $ 419,032 426,703 439,525 Contingent rentals 125,406 123,152 118,839 Sublease rental income (4,577 ) (4,979 ) (4,867 ) $ 539,861 544,876 553,497 As of December 31, 2016 , future minimum lease payments for all noncancelable operating leases and related subleases are as follows: Year Minimum Rental Commitments Sublease Rental Income Net (Amounts are in thousands) 2017 $ 428,303 4,869 423,434 2018 405,174 3,968 401,206 2019 375,484 3,601 371,883 2020 337,991 440 337,551 2021 301,747 230 301,517 Thereafter 1,893,907 1,066 1,892,841 $ 3,742,606 14,174 3,728,432 The Company also owns shopping centers which are leased to tenants for minimum monthly rentals plus contingent rentals. Minimum rentals represent fixed lease obligations, including insurance and maintenance. Contingent rentals represent variable lease obligations, including real estate taxes, insurance, maintenance and, for certain premises, excess rent. Rental income was $133,656,000 , $95,519,000 and $63,026,000 for 2016 , 2015 and 2014 , respectively. As of December 31, 2016 , future minimum rental payments to be received for all noncancelable operating leases are as follows: Year (Amounts are in thousands) 2017 $ 105,570 2018 88,336 2019 69,811 2020 52,371 2021 32,995 Thereafter 125,202 $ 474,285 (b) Letters of Credit As of December 31, 2016 , the Company had outstanding $7,597,000 in trade letters of credit and $11,799,000 in standby letters of credit to support certain purchase obligations. (c) Litigation The Company is subject from time to time to various lawsuits, claims and charges arising in the normal course of business. The Company believes its recorded reserves are adequate in light of the probable and estimable liabilities. The estimated amount of reasonably possible losses for lawsuits, claims and charges, individually and in the aggregate, is considered to be immaterial. In the opinion of management, the ultimate resolution of these legal proceedings will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

Fiscal Year	Fiscal Year The Company’s fiscal year ends on the last Saturday in December. Fiscal year 2016 includes 53 weeks and fiscal years 2015 and 2014 include 52 weeks.
Cash Equivalents	Cash Equivalents The Company considers all liquid investments with maturities of three months or less to be cash equivalents.
Trade Receivables	Trade Receivables Trade receivables primarily include amounts due from vendor allowances, debit and credit card sales and third party insurance pharmacy billings.
Inventories	Inventories Inventories are valued at the lower of cost or market. The cost for 83% and 84% of inventories was determined using the dollar value last-in, first-out (LIFO) method as of December 31, 2016 and December 26, 2015 , respectively. Under this method, inventory is stated at cost, which is determined by applying a cost-to-retail ratio to each similar merchandise category’s ending retail value. The cost of the remaining inventories was determined using the first-in, first-out (FIFO) method. The FIFO cost of inventory approximates replacement or current cost. The FIFO method is used to value manufactured, seasonal, certain perishable and other miscellaneous inventory items because of fluctuating costs and inconsistent product availability. The Company also reduces inventory for estimated losses related to shrink. If all inventories were valued using the FIFO method, inventories and current assets would have been higher than reported by $441,860,000 and $446,503,000 as of December 31, 2016 and December 26, 2015 , respectively.
Investments	Investments Debt and equity securities are classified as available-for-sale (AFS) and carried at fair value. The Company evaluates whether AFS securities are other-than-temporarily impaired (OTTI) based on criteria that include the extent to which cost exceeds market value, the duration of the market value decline, the credit rating of the issuer or security, the failure of the issuer to make scheduled principal or interest payments and the financial health and prospects of the issuer or security. Declines in the value of AFS securities determined to be OTTI are recognized in earnings and reported as OTTI losses. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the debt security or if the Company will be required to sell the debt security prior to any anticipated recovery. If the Company determines that a debt security is OTTI under these circumstances, the impairment recognized in earnings is measured as the difference between the amortized cost and the current fair value. A debt security is also determined to be OTTI if the Company does not expect to recover the amortized cost of the debt security. However, in this circumstance, if the Company does not intend to sell the debt security and will not be required to sell the debt security, the impairment recognized in earnings equals the estimated credit loss as measured by the difference between the present value of expected cash flows and the amortized cost of the debt security. Expected cash flows are discounted using the debt security’s effective interest rate. An equity security is determined to be OTTI if the Company does not expect to recover the cost of the equity security. Declines in the value of AFS securities determined to be temporary are reported net of income taxes as other comprehensive losses and included as a component of stockholders’ equity. Interest and dividend income, amortization of premiums, accretion of discounts and realized gains and losses on AFS securities are included in investment income. Interest income is accrued as earned. Dividend income is recognized as income on the ex-dividend date of the security. The cost of AFS securities sold is based on the FIFO method.
Property, Plant and Equipment and Depreciation	Property, Plant and Equipment and Depreciation Assets are recorded at cost and are depreciated using the straight-line method over their estimated useful lives or the terms of the related leases, if shorter, as follows: Buildings and improvements 10–40 years Furniture, fixtures and equipment 3–20 years Leasehold improvements 10–20 years Maintenance and repairs are charged to operating expenses as incurred. Expenditures for renewals and betterments are capitalized. The gain or loss realized on disposed assets or assets to be disposed of is recorded as operating and administrative expenses in the consolidated statements of earnings.
Long-Lived Assets	Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the net book value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the net book value of an asset to the future net undiscounted cash flows expected to be generated by the asset. An impairment loss is recorded for the excess of the net book value over the fair value of the asset. The fair value is estimated based on expected discounted future cash flows. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell and are no longer depreciated. Long-lived assets, including buildings and improvements, leasehold improvements, and furniture, fixtures and equipment, are evaluated for impairment at the supermarket level.
Self-Insurance	Self-Insurance The Company is self-insured for health care claims and property, plant and equipment losses. The Company has insurance coverage for losses in excess of self-insurance limits for workers’ compensation, general liability and fleet liability claims. Self-insurance reserves are established for health care, workers’ compensation, general liability and fleet liability claims. These reserves are determined based on actual claims experience and an estimate of claims incurred but not reported including, where necessary, actuarial studies. Actuarial projections of losses for general liability and workers’ compensation claims are discounted.
Postretirement Benefit	Postretirement Benefit The Company provides a postretirement life insurance benefit for certain salaried and hourly full-time employees who meet the eligibility requirements. Effective January 1, 2002, the Company amended the postretirement life insurance benefit under its Group Life Insurance Plan. To receive the postretirement life insurance benefit after the amendment, an employee must have had at least five years of full-time service and the employee’s age plus years of credited service must have equaled 65 or greater as of October 1, 2001. At retirement, such employees also must be at least age 55 with at least 10 years of full-time service to be eligible to receive the postretirement life insurance benefit. Actuarial projections are used to calculate the year end postretirement benefit obligation, discounted using a yield curve methodology based on high quality bonds with a rating of AA or better. Actuarial losses are amortized from accumulated other comprehensive earnings into net periodic postretirement benefit cost over future years when the accumulation of such losses exceeds 10% of the year end postretirement benefit obligation.
Comprehensive Earnings	Comprehensive Earnings Comprehensive earnings include net earnings and other comprehensive earnings. Other comprehensive earnings include revenues, expenses, gains and losses that have been excluded from net earnings and recorded directly to stockholders’ equity. Included in other comprehensive earnings for the Company are unrealized gains and losses on AFS securities and adjustments to the postretirement benefit obligation.
Revenue Recognition	Revenue Recognition Revenue is recognized at the point of sale for retail sales. Customer returns are immaterial. Vendor coupons that are reimbursed are accounted for as sales. Coupons and other sales incentives offered by the Company that are not reimbursed are recorded as a reduction of sales.
Sales Taxes	Sales Taxes The Company records sales net of applicable sales taxes.
Other Operating Income	Other Operating Income Other operating income is recognized on a net revenue basis as earned. Other operating income includes income generated from other activities, primarily lottery commissions, licensee sales commissions, automated teller transaction fees, mall gift card commissions, vending machine commissions, money transfer fees and coupon redemption income.
Cost of Merchandise Sold	Cost of Merchandise Sold Cost of merchandise sold includes costs of inventory and costs related to in-store production. Cost of merchandise sold also includes inbound freight charges, purchasing and receiving costs, warehousing costs and other costs of the Company’s distribution network. Allowances and credits, including cooperative advertising allowances, received from a vendor in connection with the purchase or promotion of the vendor’s products are recognized as a reduction of cost of merchandise sold as earned. These allowances and credits are recognized as earned in accordance with the underlying agreement with the vendor and completion of the earnings process. Short-term vendor agreements with advance payment provisions are recorded as a current liability and recognized over the appropriate period as earned according to the underlying agreements. Long-term vendor agreements with advance payment provisions are recorded as a noncurrent liability and recognized over the appropriate period as earned according to the underlying agreements.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and were $260,367,000 , $248,454,000 and $232,499,000 for 2016 , 2015 and 2014 , respectively.
Other Nonoperating Income, net	Other Nonoperating Income, net Other nonoperating income, net includes rent received from tenants in owned shopping centers, net of related expenses, and other miscellaneous nonoperating income.
Income Taxes	Income Taxes Deferred tax assets and liabilities are established for temporary differences between financial and tax reporting bases and are subsequently adjusted to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The Company recognizes accrued interest and penalties related to income tax liabilities as a component of income tax expense. The Company invests in certain investment related tax credits that promote affordable housing and renewable energy. These investments generate a return primarily through the realization of federal and state tax credits and other tax benefits. The Company accounts for its affordable housing investments using the proportional amortization method. Under this method, the investment is amortized into income tax expense in proportion to the tax credits received and the investment tax credits are recognized as a reduction of income tax expense. The Company accounts for its renewable energy investments using the deferral method. Under this method, the investment tax credits are recognized as a reduction of the renewable energy investments.
Common Stock and Earnings Per Share	Common Stock and Earnings Per Share Basic and diluted earnings per share are calculated by dividing net earnings by the weighted average shares outstanding. Basic and diluted earnings per share are the same because the Company does not have options or other stock compensation programs that impact the calculation of diluted earnings per share. All shares owned by the Employee Stock Ownership Plan (ESOP) are included in the earnings per share calculations. Dividends paid to the ESOP, as well as dividends on all other common stock shares, are reflected as a reduction of retained earnings. All common stock shares, including ESOP and 401(k) Plan shares, receive one vote per share and have the same dividend rights. The voting rights for ESOP shares allocated to participants’ accounts are passed through to the participants. The Trustee of the Company’s common stock in the 401(k) Plan votes the shares held in that plan.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of 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.
