Presentation Of Interim Information	'
	1.   Presentation of Interim Information
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the results for the interim periods presented have been included. The preparation of condensed consolidated financial statements requires us to make estimates and assumptions. These estimates and assumptions affected reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and assumptions.  Operating results for the thirteen and twenty-six weeks ended November 30, 2013 are not necessarily indicative of the results that may be expected for the year ending May 31, 2014.
	The condensed consolidated balance sheet at June 1, 2013 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.
	For further information, refer to the consolidated financial statements and footnotes thereto included in Cal-Maine Foods, Inc.'s annual report on Form 10-K for the fiscal year ended June 1, 2013. References to “we,” “us,” “our,” or the “Company” refer to Cal-Maine Foods, Inc.

	Financial Instruments
	The Company maintains cash collateralized standby letters of credit (“LOC”), for the benefit of certain insurance companies, with a bank totaling $2,973 at November 30, 2013.  The cash that collateralizes the LOCs is included in the line item “Other long-lived assets” in the condensed consolidated balance sheets. None of the LOCs are recorded as a liability on the consolidated balance sheets.
	Legal Contingencies
	The Company is a defendant in certain legal actions, and intends to vigorously defend its position in these actions.  If the Company’s assessment of a contingency indicates it is probable a material loss has been incurred and the amount of the liability can be reasonably estimated, the estimated liability is accrued in the Company’s financial statements.    If the assessment indicates a potentially material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed.
	These legal actions are discussed in detail at Part II, Item 1, of this report.

Accrued Dividends Payable And Dividends Per Common Share	'
	6.   Accrued Dividends Payable and Dividends per Common Share
	We make an accrual of dividends payable at the end of each quarter according to the Company’s dividend policy adopted by its Board of Directors. According to the dividend policy, the Company pays a dividend to shareholders of its Common Stock and Class A Common Stock on a quarterly basis for each quarter for which the Company reports net income attributable to Cal-Maine Foods, Inc. computed in accordance with generally accepted accounting principles in an amount equal to one-third (1/3) of such quarterly income. Dividends are paid to shareholders of record as of the 60th day following the last day of such quarter, except for the fourth fiscal quarter.  For the fourth quarter, the Company will pay dividends to shareholders of record on the 70th day after the quarter end. Dividends are payable on the 15th day following the record date. 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. The amount of the accrual appears on the Condensed Consolidated Balance Sheets as “Accrued dividends payable.”
	In the fourth quarter of fiscal 2013 the Company reported a net loss attributable to Cal-Maine Foods, Inc. of $3,833.  As a result total dividends paid for the twenty-six weeks ended November 30, 2013 are calculated only on net income attributable to Cal-Maine Foods, Inc. in excess of $3,833.
	On our condensed consolidated statement of income, we determine dividends per common share in accordance with the computation in the following table (shares in thousands):
		13 Weeks Ended				26 Weeks Ended

	7. Derivative Financial Instruments
	The Company holds commodity futures contracts in the form of call options, the cost of which is paid for by customers, to protect against increases in the price of corn and soybean meal purchases required to support that portion of its shell egg production sold on a cost of production formula.  The contracts are generally for durations of less than six months.  The Company elected to mark the unrealized changes in derivative instrument fair value to market; however, the net realized cost of these contracts is paid by customers, so there is no net impact to the Company’s Consolidated Statement of Income.  The fair value of all derivative instruments outstanding is included as a component of Prepaid Expenses and Other Current Assets on the Condensed Consolidated Balance Sheets as follows:

Fair Value Measurements	'
	8.   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 disclosure 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.  Except for the “Notes payable-Texas Egg Products, LLC,” fair values for debt are based on quoted market prices or published forward interest rate curves.    We believe cost approximates fair value for the “Notes payable-Texas Egg Products, LLC.”  Estimated fair values are management’s estimates; however, when there is no readily available market data, the estimated fair values may not represent the amounts that could be realized in a current transaction, and the fair values could change significantly. There is no readily available market data for the “Note Payable-Texas Egg Products, LLC.”  The fair value and carrying value of the Company’s borrowings under its credit facilities and long-term debt were as follows:
		30-Nov-13						1-Jun-13
		Carrying Value			Fair Value			Carrying Value			Fair Value
	5.99 – 6.4% Notes payable	$	49,640		$	50,711		$	54,240		$	56,237

	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 that are required to be measured at fair value on a recurring basis as of November 30, 2013 and June 1, 2013:

	Our investment securities – available-for-sale classified as level 2 consist of certificates of deposit, United States government obligations, government agency bonds, taxable municipal bonds,  tax exempt municipal bonds, zero coupon municipal bonds, and corporate bonds. We classified these securities as current, because amounts invested are available for current operations. Observable inputs for these securities are yields, credit risks, default rates, and volatility.
	The Company applies fair value accounting guidance to measure non-financial assets and liabilities associated with business acquisitions. These assets and liabilities are measured at fair value for the initial purchase price allocation and are subject to recurring revaluations. The fair value of non-financial assets acquired is determined internally.  Our internal valuation methodology for non-financial assets takes into account the remaining estimated life of the assets acquired and what management believes is the market value for those assets based on their highest and best use.  Liabilities for contingent consideration (earn-outs) take into account commodity prices based on published forward commodity price curves, projected future egg prices as of the date of the estimate, and projected future cash flows expected to be received as a result of a business acquisition (Refer to Note 2 in the Annual Report on Form 10-K).  Given the unobservable nature of these inputs, they are deemed to be Level 3 fair value measurements.  During the twenty-six week period ended November 30, 2013 we recognized $1,492 in expense resulting from the increase in fair value of the contingent consideration.  This expense was recognized in earnings as an increase of selling, general, and administrative expenses.  Changes in the fair value of contingent consideration obligations were as follows:
			Twenty-six weeks ended November 30, 2013
	Balance at June 1, 2013	$	1,250
	Expense recognized in earnings		1,492
	Actual payments made		-1,448
	Balance at November 30, 2013	$	1,294

	Proceeds from the sales of available-for-sale securities were $52,409 and  $157,179 during the twenty-six week periods ending November 30, 2013 and December 1, 2012, respectively. Gross realized gains on those sales during the twenty-six week periods ending November 30, 2013 and December 1, 2012 were $4 and $1, respectively.  Gross realized losses on those sales during the twenty-six week periods ending November 30, 2013 and December 1, 2012 were $2 and $203, respectively. For purposes of determining gross realized gains and losses, the cost of securities sold is based on the specific identification method. Unrealized holding gains net of tax on available-for-sale securities were $139 and  $137 for the twenty-six week period ending November 30, 2013 and December 1, 2012, respectively.  The unrealized holding gains net of tax have been included in accumulated other comprehensive income.
	Contractual maturities of available-for-sale debt securities at November 30, 2013, are as follows:

	After 5-10 years		-
	Total	$	150,893
	Actual maturities may differ from contractual maturities because some borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

	10.   Guarantee
	The Company owns 50% of the membership interests in Delta Egg Farm, LLC (“Delta Egg”), and is a guarantor of 50% of approximately $7,215 of Delta Egg’s long-term debt at November 30, 2013.  The other 50% owner guarantees 50% of the debt.  Delta Egg’s long-term debt is secured by substantially all of the fixed assets of Delta Egg and is due in monthly installments through fiscal 2018.  Delta Egg is engaged in the production, processing, and distribution of shell eggs.   Payment under the guarantee would be required if Delta Egg is unable to pay the debt.  Management believes payment under the guarantee is unlikely because Delta Egg is well capitalized.

	In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”).  This update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component.  In addition, ASU 2013-02 requires presentation, either on the face of the income statement or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by respective line items of net income, but only if the amounts reclassified are required to be reclassified in their entirety in the same reporting period.  For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about these amounts.  The amendments in ASU 2013-02 are effective prospectively for annual reporting periods beginning after December 15, 2012, and interim periods within those annual periods.  ASU 2013-02 became effective for the Company with the quarter ended August 31, 2013.  The adoption of ASU 2013-02 did not have a material effect on the Company’s financial statements.
