Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements of Cal-Maine Foods, Inc. and its subsidiaries (the "Company," "we," "us," "our") have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Therefore, they do not include all of the information and footnotes required by generally accepted accounting principles (GAAP) in the United States of America for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended June 1, 2019. These statements reflect all adjustments that are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented and, in the opinion of management, consist of adjustments of a normal recurring nature. Operating results for the interim periods are not necessarily indicative of operating results for the entire fiscal year. Fiscal Year The Company's fiscal year-end is on the Saturday nearest May 31. Each of the three-month periods and year-to-date periods ended on November 30, 2019 and December 1, 2018 included 13 and 26 weeks, respectively. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that effect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Leases The Company determines if an arrangement is a lease at inception of the arrangement and classifies it as an operating lease or finance lease. We recognize the right to use an underlying asset for the lease term as a right-of-use (ROU) asset on our balance sheet. A lease liability is recorded to represent our obligation to make lease payments over the term of the lease. These assets and liabilities are included in our Condensed Consolidated Balance Sheet in Finance lease right-of-use asset, Operating lease right-of-use asset, Current portion of finance lease obligation, Current portion of operating lease obligation, Long-term finance lease obligation, and Long-term operating lease obligation. The Company records ROU assets and lease obligations based on the discounted future minimum lease payments over the term of the lease. When the rate implicit in the lease is not easily determinable, the Company’s incremental borrowing rate is used to calculate the present value of the future lease payments. The Company elected not to recognize ROU assets and lease obligations for leases with an initial term of 12 months or less. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Nature of Leases The company leases certain office spaces, trucks, processing machines, and equipment to support our operations under cancelable and non-cancelable contracts. Corporate and Field Offices We lease office space for administrative employees at some of our farms. These contracts are typically structured with initial non-cancelable terms of three to ten years. To the extent our corporate and field office contracts include renewal options, we evaluate whether we are reasonably certain to exercise those options on a contract by contract basis based on expected future office space needs. Trucks We assumed several non-cancelable operating leases for trucks from a prior acquisition. The initial terms on these leases ranged from five to seven years. We do not intend to exercise renewal options beyond the initial term. Processing machines and other equipment We lease a processing machine through a finance lease arrangement assumed in an acquisition. The lease contains a purchase option at the end of the term that we intend to exercise. The company leases various pieces of equipment such as forklifts, pallet jacks, and other items in support of operations. These leases are cancelable and non-cancelable with terms ranging from one month to five years. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases. The purpose of the standard is to improve transparency and comparability related to the accounting and reporting of leasing arrangements. The new standard establishes a ROU model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations. The effective date for the new standard, for the Company, was June 2, 2019 and the Company adopted the new standard on that date. The Company elected a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either its effective date or the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We used June 2, 2019 as the date of initial application. If an entity chooses the second option, the transition requirements for existing leases apply to leases entered into between the date of initial application and the effective date. The entity must recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. Because the Company chose the first option, the Company has not recast its comparative period financial statements. In connection with adopting the new standard, the Company reclassified its presentation of finance lease obligations and property in the financial statements for all periods presented. The new standard provides a number of optional practical expedients in transition. The Company elected practical expedients which permit us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard provides practical expedients for an entity’s initial and ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. For the leases that qualify, we do not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. Implementation of the new standard did not have a material effect on our financial statements. See Note for additional information. Reclassification Certain reclassifications were made to the fiscal 2019 financial statements to conform to the fiscal 2020 financial statement presentation. These reclassifications had no effect on income

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company is required to categorize both financial and nonfinancial assets and liabilities based on the following fair value hierarchy. The fair value of an asset is the price at which the asset could be sold in an orderly transaction between unrelated, knowledgeable, and willing parties able to engage in the transaction. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor in a transaction between such parties, not the amount that would be paid to settle the liability with the creditor. • Level 1 - Quoted prices in active markets for identical assets or liabilities • Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly • Level 3 - Unobservable inputs for the asset or liability that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities The disclosures of fair value of certain financial assets and liabilities that are recorded at cost are as follows: Cash and cash equivalents: The carrying amount approximates fair value due to the short maturity of these instruments. Long-term debt: The carrying value of the Company’s long-term debt is at its stated value. We have not elected to carry our long-term debt at fair value. Fair values for debt are based on quoted market prices or published forward interest rate curves, which are level 2 inputs. The fair value and carrying value of the Company’s borrowings under its long-term debt were as follows (in thousands): November 30, 2019 June 1, 2019 Carrying Value Fair Value Carrying Value Fair Value Liabilities Note payable $ — $ — $ 1,500 $ 1,501 Finance lease obligations 957 867 1,054 940 Total liabilities measured at fair value $ 957 $ 867 $ 2,554 $ 2,441 Assets and Liabilities Measured at Fair Value on a Recurring Basis In accordance with the fair value hierarchy described above, the following table shows the fair value of financial assets and liabilities measured at fair value on a recurring basis as of November 30, 2019 and June 1, 2019 (in thousands): ໿ Total November 30, 2019 Level 1 Level 2 Level 3 Balance Assets US government and agency obligations $ — $ 10,637 $ — $ 10,637 Municipal bonds — 25,422 — 25,422 Corporate bonds — 84,608 — 84,608 Certificates of deposits — 1,004 — 1,004 Asset backed securities — 1,604 — 1,604 Mutual funds 2,593 — — 2,593 Total assets measured at fair value $ 2,593 $ 123,275 $ — $ 125,868 ໿ June 1, 2019 Level 1 Level 2 Level 3 Balance Assets US government and agency obligations $ — $ 30,974 $ — $ 30,974 Municipal bonds — 50,353 — 50,353 Commercial paper — 9,945 — 9,945 Corporate bonds — 147,162 — 147,162 Certificates of deposits — 6,148 — 6,148 Asset backed securities — 5,599 — 5,599 Mutual funds 3,357 — — 3,357 Total assets measured at fair value $ 3,357 $ 250,181 $ — $ 253,538 Investment securities – available-for-sale have maturities of three months or longer when purchased, and are classified as current, because they are available for current operations.

Following a quarter for which the Company does not report net income attributable to Cal-Maine Foods, Inc., the Company will not pay a dividend for a subsequent profitable quarter until the Company is profitable on a cumulative basis computed from the date of the last quarter for which a dividend was paid. At the end of the second quarter of fiscal 2020, the amount of cumulative losses to be recovered before payment of a dividend was $75.6 million. On our condensed consolidated statement of operations, we determine dividends per common share in accordance with the computation in the following table (in thousands, except per share data): 13 Weeks Ended 26 Weeks Ended November 30, 2019 December 1, 2018 November 30, 2019 December 1, 2018 Net income (loss) attributable to Cal-Maine Foods, Inc. available for dividend $ (10,061) $ 21,807 $ (55,821) $ 34,212 1/3 of net income attributable to Cal-Maine Foods, Inc. available for dividend $ — $ 7,246 $ — $ 11,381 Common stock outstanding (shares) 43,893 43,828 Class A common stock outstanding (shares) 4,800 4,800 Total common stock outstanding (shares) 48,693 48,628 Dividends per common share* $ — $ 0.149 $ — $ 0.234 *Dividends per common share = 1/3 of Net income (loss) attributable to Cal-Maine Foods, Inc. available for dividend ÷ Total common stock outstanding (shares).

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Satisfaction of Performance Obligation The vast majority of the Company’s revenue is derived from contracts with customers based on the customer placing an order for products. Pricing for the most part is determined when the Company and the customer agree upon the specific order, which establishes the contract for that order. Revenues are recognized in an amount that reflects the net consideration we expect to receive in exchange for the goods. Our shell eggs are sold at prices related to Urner Barry Spot Egg Market Quotations, negotiated prices or formulas related to our costs of production. The Company’s sales predominantly contain a single performance obligation. We recognize revenue upon satisfaction of the performance obligation with the customer which typically occurs within days of the Company and the customer agreeing upon the order. Returns and Refunds Some of our contracts include a guaranteed sale clause, pursuant to which we credit the customer’s account for product that the customer is unable to sell before expiration. The Company records an estimate of returns and refunds by using historical return data and comparing to current period sales and accounts receivable. The allowance is recorded as a reduction in sales with a corresponding reduction in trade accounts receivable. Disaggregation of Revenue The following table provides revenue disaggregated by product category (in thousands): 13 Weeks Ended 26 Weeks Ended November 30, 2019 December 1, 2018 November 30, 2019 December 1, 2018 Non-specialty shell egg sales $ 186,960 $ 216,324 $ 308,569 $ 424,486 Specialty shell egg sales 109,351 120,839 214,420 233,102 Co-pack specialty shell egg sales 6,540 6,636 12,679 13,003 Egg products 7,797 11,082 14,998 23,135 Other 874 1,159 2,022 2,897 $ 311,522 $ 356,040 $ 552,688 $ 696,623 Contract Costs The Company can incur costs to obtain or fulfill a contract with a customer. The amortization period of these costs is less than one year; therefore, they are expensed as incurred. Contract Balances The Company receives payment from customers based on specified terms that are generally less than 30 days from delivery. There are rarely contract assets or liabilities related to performance under the contract.

Earnings Per Share [Abstract]
Net Income (Loss) per Common Share	Net Income (Loss) per Common Share Basic net loss per share was calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share was calculated by dividing net income by the weighted-average number of common shares outstanding during the period plus the dilutive effects of options and restricted stock. Due to the net loss in the thirteen weeks ended and twenty-six weeks ended November 30, 2019, restricted shares were excluded from the calculation of diluted net loss per share because their inclusion would have been antidilutive. The computations of basic and diluted net loss per share attributable to the Company are as follows (in thousands, except per share data): 13 Weeks Ended 26 Weeks Ended November 30, 2019 December 1, 2018 November 30, 2019 December 1, 2018 Net income (loss) attributable to Cal-Maine Foods, Inc. $ (10,061) $ 21,807 $ (55,821) $ 34,212 Basic weighted-average common shares 48,447 48,391 48,447 48,390 Effect of dilutive securities: Restricted shares — 143 — 135 Dilutive potential common shares 48,447 48,534 48,447 48,525 Antidilutive securities excluded from computation of earnings per share 135 — 123 — Net income (loss) per common share attributable to Cal-Maine Foods, Inc.: Basic $ (0.21) $ 0.45 $ (1.15) $ 0.71 Diluted $ (0.21) $ 0.45 $ (1.15) $ 0.71

Commitments and Contingencies Disclosure [Abstract]
Commitment and Contingencies	Commitment and Contingencies Financial Instruments The Company maintained standby letters of credit (LOC) totaling $4.2 million at November 30, 2019 that were issued under our Revolving Credit Facility. The outstanding LOCs are for the benefit of certain insurance companies, and are not recorded as a liability on the consolidated balance sheets. Egg Antitrust Litigation On September 25, 2008, the Company was named as one of several defendants in numerous antitrust cases involving the United States shell egg industry. The cases were consolidated into In re: Processed Egg Products Antitrust Litigation, No. 2:08-md-02002-GP, in the United States District Court for the Eastern District of Pennsylvania (the “District Court”), in three groups of cases - the “Direct Purchaser Putative Class Action”, the “Indirect Purchaser Putative Class Action” and the “Non-Class Cases.” As previously reported, the Company settled all of the Direct Purchaser Putative Class Action cases and the Indirect Purchaser Putative Class Action cases, and all Non-Class cases except for the claims of certain plaintiffs who sought substantial damages allegedly arising from the purchase of egg products (as opposed to shell eggs). In addition, as previously reported, the Company settled all claims brought by one of these plaintiffs, Conopco, Inc., and the Court entered a final judgment dismissing Conopco’s claims against the Company on November 21, 2018. On October 24, 2019, the Company entered into a confidential settlement agreement with The Kellogg Company dismissing all claims against the Company for an amount that does not have a material impact on the Company’s financial condition or results of operations. On November 11, 2019, a stipulation for dismissal was filed with the court, but the court has not yet entered a judgment on the filing. The remaining plaintiffs are Kraft Food Global, Inc., General Mills, Inc., and Nestle USA, Inc. (“Egg Products Plaintiffs”). The Egg Products Plaintiffs seek treble damages and injunctive relief under the Sherman Act and are attacking certain features of the UEP animal-welfare guidelines and program used by the Company and many other egg producers. On July 2, 2019 the Egg Products Plaintiffs filed a motion to remand, and on September 13, 2019 the case was remanded to the United States District Court for the Northern District of Illinois, Kraft Foods Global, Inc. et al v. United Egg Producers, Inc. et al, No. 1:11-cv-08808 (DP), where it was initially filed, for trial. The Illinois court has not issued a case management order or any other directive. The Company intends to continue to defend the remaining case as vigorously as possible based on defenses which the Company believes are meritorious and provable. While management believes that the likelihood of a material adverse outcome in the overall egg antitrust litigation has been significantly reduced as a result of the settlements and rulings described above, there is still a reasonable possibility of a material adverse outcome in the remaining egg antitrust litigation. At the present time, however, it is not possible to estimate the amount of monetary exposure, if any, to the Company because of this remaining case. Adjustments, if any, which might result from the resolution of these remaining legal matters, have not been reflected in the financial statements. Other Matters In addition to the above, the Company is involved in various other claims and litigation incidental to its business. Although the outcome of these matters cannot be determined with certainty, management, upon the advice of counsel, is of the opinion that the final outcome should not have a material effect on the Company’s consolidated results of operations or financial position.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Nov. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements of Cal-Maine Foods, Inc. and its subsidiaries (the "Company," "we," "us," "our") have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Therefore, they do not include all of the information and footnotes required by generally accepted accounting principles (GAAP) in the United States of America for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended June 1, 2019. These statements reflect all adjustments that are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented and, in the opinion of management, consist of adjustments of a normal recurring nature. Operating results for the interim periods are not necessarily indicative of operating results for the entire fiscal year.
Fiscal Year	Fiscal Year The Company's fiscal year-end is on the Saturday nearest May 31. Each of the three-month periods and year-to-date periods ended on November 30, 2019 and December 1, 2018 included 13 and 26 weeks, respectively.
Use of Estimates	Use of EstimatesThe preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that effect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Leases	Leases The Company determines if an arrangement is a lease at inception of the arrangement and classifies it as an operating lease or finance lease. We recognize the right to use an underlying asset for the lease term as a right-of-use (ROU) asset on our balance sheet. A lease liability is recorded to represent our obligation to make lease payments over the term of the lease. These assets and liabilities are included in our Condensed Consolidated Balance Sheet in Finance lease right-of-use asset, Operating lease right-of-use asset, Current portion of finance lease obligation, Current portion of operating lease obligation, Long-term finance lease obligation, and Long-term operating lease obligation. The Company records ROU assets and lease obligations based on the discounted future minimum lease payments over the term of the lease. When the rate implicit in the lease is not easily determinable, the Company’s incremental borrowing rate is used to calculate the present value of the future lease payments. The Company elected not to recognize ROU assets and lease obligations for leases with an initial term of 12 months or less. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Nature of Leases The company leases certain office spaces, trucks, processing machines, and equipment to support our operations under cancelable and non-cancelable contracts. Corporate and Field Offices We lease office space for administrative employees at some of our farms. These contracts are typically structured with initial non-cancelable terms of three to ten years. To the extent our corporate and field office contracts include renewal options, we evaluate whether we are reasonably certain to exercise those options on a contract by contract basis based on expected future office space needs. Trucks We assumed several non-cancelable operating leases for trucks from a prior acquisition. The initial terms on these leases ranged from five to seven years. We do not intend to exercise renewal options beyond the initial term. Processing machines and other equipment We lease a processing machine through a finance lease arrangement assumed in an acquisition. The lease contains a purchase option at the end of the term that we intend to exercise. The company leases various pieces of equipment such as forklifts, pallet jacks, and other items in support of operations. These leases are cancelable and non-cancelable with terms ranging from one month to five years.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases. The purpose of the standard is to improve transparency and comparability related to the accounting and reporting of leasing arrangements. The new standard establishes a ROU model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations. The effective date for the new standard, for the Company, was June 2, 2019 and the Company adopted the new standard on that date. The Company elected a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either its effective date or the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We used June 2, 2019 as the date of initial application. If an entity chooses the second option, the transition requirements for existing leases apply to leases entered into between the date of initial application and the effective date. The entity must recast its comparative period financial statements and provide the disclosures required by the new standard for the comparative periods. Because the Company chose the first option, the Company has not recast its comparative period financial statements. In connection with adopting the new standard, the Company reclassified its presentation of finance lease obligations and property in the financial statements for all periods presented. The new standard provides a number of optional practical expedients in transition. The Company elected practical expedients which permit us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The new standard provides practical expedients for an entity’s initial and ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. For the leases that qualify, we do not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. Implementation of the new standard did not have a material effect on our financial statements. See Note for additional information.
