ITEM 1.  BUSINESS

Our Business

Cal-Maine Foods, Inc. (“we,” “us,” “our,” or the “Company”) is the largest producer and marketer of shell eggs in the United States. In fiscal 2016, we sold approximately 1,053.6 million dozen shell eggs, which we believe represented approximately 23% of domestic shell egg consumption. Our total flock of approximately 33.9 million layers and 9.4 million pullets and breeders is the largest in the U.S.  Layers are mature female chickens, pullets are young female chickens usually under 18 weeks of age, and breeders are male and female chickens used to produce fertile eggs to be hatched for egg production flocks.

The Company has one operating segment, which is the production, grading, packaging, marketing and distribution of shell eggs.  The majority of our customers rely on us to provide most of their shell egg needs, including specialty and non-specialty eggs. Specialty eggs represent a broad range of products.  We classify nutritionally enhanced, cage free, organic and brown eggs as specialty products for accounting and reporting purposes. We classify all other shell eggs as non-specialty products.  While we report separate sales information for these types of eggs, there are a number of cost factors which are not specifically available for non-specialty or specialty eggs due to the nature of egg production. We manage our operations and allocate resources to these types of eggs on a consolidated basis based on the demands of our customers.

We sell most of our shell eggs in the southwestern, southeastern, mid-western and mid-Atlantic regions of the U.S. We market our shell eggs through our extensive distribution network to a diverse group of customers, including national and regional grocery store chains, club stores, foodservice distributors and egg product consumers. Some of our sales are completed through co-pack agreements – a common practice in the industry whereby production and processing of certain products is outsourced to another producer.  The strength of our position is evidenced by having the largest market share in the grocery segment for shell eggs.  We sell shell eggs to a majority of the largest food retailers in the U.S.

We are one of the largest producers and marketers of value-added specialty shell eggs in the U.S. For accounting and tax purposes, we classify nutritionally enhanced, cage-free, organic and brown eggs as specialty shell eggs.They have been a significant and growing segment of the market in recent years.  During our fiscal 2016 an increasing number of food service customers, large restaurant chains, and major retailers, including our largest customers, have committed to exclusive offerings of cage-free eggs by specified future dates. We are working with our customers to ensurea  smooth transition in meeting their goals, and have been

3

making and expect to continue to make significant investments in new and remodeled facilities to meet this demand. In fiscal 2016, specialty shell eggs and co-pack specialty shell eggs represented 29.1% and 2.7% of our shell egg sales dollars, respectively, and accounted for approximately 22.9% and 2.0%, respectively, of our total shell egg volumes. In fiscal 2015, specialty shell eggs and co-pack specialty shell eggs represented 27.2% and 2.8% of our shell egg sales dollars, respectively, and accounted for approximately 19.8% and 2.0%, respectively, of our total shell egg volumes.  Prices for specialty eggs are less cyclical than non-specialty shell egg prices and are generally higher due to consumer willingness to pay for the perceived increased benefits from those products. We market our specialty shell eggs under the following brands: Egg-Land’s Best®,  Land O’ Lakes®, Farmhouse®, and 4-Grain®.  We are a member of the Egg-Land’s Best, Inc. (“EB”) cooperative and produce, market and distribute Egg-Land’s Best® and Land O’ Lakes®  branded eggs, along with our associated joint ventures, under  exclusive license agreements for a number of states in the southeast, south central, and southwest U.S.as well as the New York City area.  We market cage-free eggs under our trademarked Farmhouse® brand and distribute them across the southeast and southwest regions of the U.S.  We market organic, wholesome, cage-free, vegetarian, and omega-3 eggs under our 4-Grain® brand. We also produce, market, and distribute private label specialty shell eggs to several customers.

We are a leader in industry consolidation. Since 1989, we have completed eighteen acquisitions ranging in size from 600,000 layers to 7.5 million layers.  Despite a market that has been characterized by increasing consolidation, the shell egg production industry remains highly fragmented. At December 31, 2015, 56 producers, owning at least one million layers, owned approximately 96% of total industry layers and the ten largest producers owned approximately 50% of total industry layers. We believe industry consolidation will continue and we plan to capitalize on opportunities as they arise.

Industry Background 

Based on historical consumption trends, demand for shell eggs increases in line with overall population growth, averaging growth of about 1% per year. In  2013 and 2014,  consumption of eggs grew approximately 2% per year.  However in 2015, egg consumption decreased approximately 4% over the prior year primarily due to a shortage of supply of egg products.  According to U.S. Department of Agriculture (“USDA”), annual per capita U.S. consumption varied between 249 and 263 eggs, since 2000. In calendar year 2015, per capita U.S. consumption was estimated to be 253 eggs, or approximately five eggs per person per week.  Per capita consumption is determined by dividing the total supply of eggs by the entire population in the U.S. (i.e. all eggs supplied domestically by the egg industry are consumed).  

While the data can vary somewhat from year to year, of eggs produced in the U.S., approximately 55% are sold to retail consumers (e.g. through grocery and convenience stores), approximately 31% are sold as egg products (shell eggs broken and sold in liquid, frozen, or dried form) to institutions (e.g. companies producing baked goods), approximately 9% are sold to food service companies and 5% or less are exported. Our sales are predominately to retail consumers; in fiscal 2016 and 2015, approximately 4% and 3% of our net sales was egg products, respectively.

Prices for Shell Eggs

Shell egg prices are a critical component of profitability for the Company and the industry as a whole. We believe the majority of shell eggs sold in the U.S. in the retail and foodservice channels are sold at prices related to the Urner Barry wholesale quotation for shell eggs. We sell the majority of our non-specialty shell eggs at prices related to Urner Barry Spot Egg Market Quotations or formulas related to our costs of production which include the cost of corn and soybean meal.  For fiscal 2016, wholesale large shell egg prices in the southeast region, as quoted by Urner Barry, averaged $1.79 per dozen compared to an average of $1.38 per dozen for fiscal years 2012 to 2015.  Egg prices during fiscal 2016 were impacted by the outbreak of avian influenza (“AI”) primarily in the upper Midwestern U.S. from April to June 2015, which initially caused a significant reduction in egg supplies and increase in egg prices and had a disproportionately large impact on suppliers of egg products.  While the AI outbreak significantly impacted the supply and prices of eggs during fiscal 2016, there were no positive tests for AI at any of our locations.  According to a USDA report as of June 1, 2016, the number of layers in the U.S. flock was up 10.2% compared to June 1, 2015, but remained 1.6% below the number of layers for June 1, 2014.  This increase, from June 1, 2015 to 2016, is due to the repopulation of flocks depleted by the AI outbreak.  The number of chicks hatched from January through May of 2016 was up 9.6% compared to the same period in 2015.  Market prices for shell eggs have dropped significantly from the historically high levels we experienced at the beginning of this fiscal year.  The Urner Barry price index hit a decade-low level during our fourth quarter, before recovering a portion of these declines in recent weeks.While retail demand trends for shell eggs have been favorable, there has been demand erosion for egg products and reduced egg exports. Based on USDA reports, the laying flock is expected to increase through the end of calendar 2016, creating more supply and the potential for further price declines.  Egg prices will likely remain volatile and future

4

prices will depend on levels of supply and the recovery of institutional demand for eggs which was adversely impacted as a result of the 2015 shortages caused by AI.

Feed Costs for Shell Egg Production

Feed is a primary cost component in the production of shell eggs and represents over half of industry farm level production costs. Most shell egg producers, including us, are vertically integrated, manufacturing the majority of the feed they require for their operations. Although feed ingredients, primarily corn and soybean meal, are available from a number of sources, prices for ingredients can fluctuate and are affected by weather, speculators, and various supply and demand factors. Our feed prices for fiscal 2016 were 5.7% lower than fiscal 2015.  The large 2015 harvest increased available supplies of corn and soybean meal and favorably impacted our fiscal 2016 results, compared to the same period of fiscal 2015.  Increased U.S. acreage for both corn and soybeans in 2016 should provide adequate domestic supplies for both of our primary feed ingredients.  Domestic corn supplies could be particularly robust,although domestic soybean stocks could be negatively impacted by increased exports due to reduced supplies from South America.

Growth Strategy and Acquisitions

For many years, we have pursued a growth strategy focused on the acquisition of existing shell egg production and processing facilities, as well as the construction of new and more efficient facilities.  Since the beginning of fiscal 1989, we have completed eighteen acquisitions. In addition, we have built numerous “in-line” shell egg production and processing facilities as well as pullet growing facilities which added to our capacity.  The capacity increases have been accompanied by the retirement of older and less efficient facilities.  The “in-line” facilities provide gathering, grading and packaging of shell eggs by less labor-intensive, more efficient, mechanical means.  Additionally, we continue to upgrade and modify our facilities, and invest in new facilities, to meet changing demand as many food service customers, restaurant chains, and retailers have committed to exclusive offerings of cage-free eggs over the next several years.

As a result of our strategy, our total flock, including pullets, layers and breeders, increased from approximately 33.5  million at May 28, 2011 to approximately 43.3 million as of May 28, 2016.  The dozens of shell eggs sold increased from approximately 821.4 million in fiscal 2011 to approximately 1,053.6 million for fiscal 2016.  Net sales amounted to $942.0 million in fiscal 2011 compared to net sales of $1,908.7 million in fiscal 2016.  

We continue to pursue opportunities to acquire companies engaged in the production and sale of shell eggs.  We will continue to evaluate and selectively pursue acquisitions that will expand our shell egg production capabilities in existing markets and broaden our geographic reach. We have extensive experience identifying, valuing, executing, and integrating acquisitions and we intend to leverage that experience in the evaluation and execution of future acquisitions. We will seek to acquire regional shell egg businesses with significant market share and long-standing customer relationships. We believe enhancing our national presence will help us further strengthen our relationships with existing customers, many of whom have operations across the U.S.

Federal antitrust laws require regulatory approval of acquisitions that exceed certain threshold levels of significance, and we are subject to federal and state laws prohibiting anti-competitive conduct.   We believe our sales of shell eggs during the last fiscal year represented approximately 23% of domestic shell egg sales, making us the largest producer and distributor of shell eggs in the U.S. However, because the shell egg production and distribution industry is so fragmented, we believe there are many acquisition opportunities available to us that would not be restricted pursuant to antitrust laws.

Through exclusive license agreements with EB in several key territories and our trademarked Farmhouse® and 4Grain® brands, we are one of the leading producers and marketers of value-added specialty shell eggs. We also produce, market, and distribute private label specialty shell eggs to several customers. Since selling prices of specialty shell eggs are generally less volatile thannon-specialty shell egg prices, we believe growing our specialty eggs business will enhance the stability of our margins.  We expect the price of specialty eggs to remain at a premium to regular shell eggs, and intend to grow our specialty shell egg business.

The construction of new, more efficient production and processing facilities is an integral part of our growth strategy.  Any such construction will require compliance with applicable environmental laws and regulations, including the receipt of permits that could cause schedule delays, although we have not experienced any significant delays in the past.

Shell Eggs

Production.  Our operations are fully integrated. We hatch chicks, grow and maintain flocks of pullets, layers, and breeders, manufacture feed, and produce, process, package, and distribute shell eggs.  We produce approximately 78% of our total shell eggs sold, with 96% of such production coming from company-owned facilities, and the other 4% coming from contract producers.  Under a typical arrangement with a contract producer, we own the flock, furnish all feed and critical supplies, own the shell eggs produced and assume market risks. The contract producers own and operate their facilities and are paid a fee based on production with incentives for performance. We purchase approximately 22% of the total shell eggs we sell from outside producers.

The commercial production of shell eggs requires a source of baby chicks for laying flock replacement. We produce the majority of our chicks in our own hatcheries and obtain the balance from commercial sources. We own breeder and hatchery facilities capable of producing 21.2 million pullet chicks per year in a computer-controlled environment. These pullets are distributed to 44 state-of-the-art laying operations around the southwestern, southeastern, mid-western and mid-Atlantic regions of the U.S. The facilities produce an average of 2.2 million dozen shell eggs per day. The shell eggs are processed, graded and packaged predominantly without handling by human hands. We have spent a cumulative total of $270.7 million over the past five years to expand and upgrade our facilities with the most advanced equipment and technology available in our industry. We believe our constant attention to production efficiencies and focus on automation throughout the supply chain enables us to be a low cost supplier in all the markets in which we compete.

Feed cost represents the largest element of our farm egg production cost, ranging from 60% to 69% of total farm production cost in the last five fiscal years. Although feed ingredients are available from a number of sources, we have little, if any, control over the prices of the ingredients we purchase, which are affected by weather, speculators, and various supply and demand factors.  For example, the severe drought in the summer of 2012 and resulting damage to the national corn and soybean crop resulted in high and volatile feed costs.  Increases in feed costs unaccompanied by increases in the selling price of eggs can have a material adverse effect on our operations.  However, higher feed costs can encourage shell egg producers to reduce production, resulting in higher egg prices.  Alternatively, low feed costs can encourage industry overproduction, possibly resulting in lower egg prices. 

After the eggs are produced, they are graded and packaged.  Substantially all of our farms have modern “in-line” facilities to mechanically gather, grade and package the eggs produced.  The increased use of in-line facilities has generated significant cost savings compared to the cost of eggs produced from non-in-line facilities.  In addition to greater efficiency, the in-line facilities produce a higher percentage of USDA Grade A eggs, which sell at higher prices.  Eggs produced on farms owned by contractors are brought to our processing plants to be graded and packaged. Since shell eggs are perishable, we maintain very low egg inventories, usually consisting of approximately four days of production.

Egg production activities are subject to risks inherent in the agriculture industry, such as weather conditions and disease.  These risks are outside our control and could have a material adverse effect on our operations.  The marketability of shell eggs is subject to risks such as possible changes in food consumption preferences and practices reflecting perceived health concerns.

We operate in a cyclical industry with total demand that is generally steady and a product that is generally price-inelastic.  Thus, small increases in production or decreases in demand can have a large adverse effect on prices and vice-versa.  However, economic conditions in the egg industry are expected to exhibit less cyclicality in the future.  The industry is concentrating into fewer but stronger hands, which should help lessen the extreme cyclicality of the past.

Marketing.  Of the 1,053.6 million dozen shell eggs sold by us in fiscal2016, our flocks produced 819.3 million.

We sell our shell eggs to a diverse group of customers, including national and local grocery store chains, club stores, foodservice distributors, and egg product consumers. We utilize electronic ordering and invoicing systems that enable us to manage inventory for certain of our customers. Our top ten customers accounted for an aggregate of 70.6%, 67.9%, and 68.5% of net sales dollars for fiscal 2016, 2015, and 2014, respectively. Two customers, Wal-Mart Stores and Sam’s Club, on a combined basis, accounted for 28.9%, 25.7%, and 28.2% of net sales dollars during fiscal 2016, 2015, and 2014, respectively.

The majority of eggs sold are sold based on the daily or short-term needs of our customers.  Most sales to established accounts are on open account with payment terms ranging from seven to 30 days.  Although we have established long-term relationships with many of our customers, many of them are free to acquire shell eggs from other sources.

6

The shell eggs we sell are either delivered to our customers’ warehouse or retail stores by our own fleet or contracted refrigerated delivery trucks, or are picked up by our customers at our processing facilities.

We sell our shell eggs at prices generally related to independently quoted wholesale market prices or at formulas related to our costs of production. Wholesale prices are subject to wide fluctuations.  The prices of shell eggs reflect fluctuations in the quoted market and changes in corn and soybean meal prices, and the results of our shell egg operations are materially affected by changes in market quotations and feed costs.  Egg prices reflect a number of economic conditions, such as the supply of eggs and the demand level, which, in turn, are influenced by a number of factors we cannot control.  No representation can be made as to the future level of prices.

According to USDA reports, for the past five years, U.S. annual per capita egg consumptiongrew from 250 in 2011 to  263in 2014, before dropping back to 253 in 2015.  We believe the decrease in consumption in 2015 is attributable to a shortage of supply and increased shell egg prices caused by a severe outbreak of avian influenza.  Looking ahead, we believe fast food restaurant consumption, high protein diet trends, reduced egg cholesterol levels, and industry advertising campaigns may result in increased per capita egg consumption levels;however,no assurance can be given that per capita consumption will not decline in the future.

We sell the majority of our shell eggs across the southwestern, southeastern, mid-western and mid-Atlantic regions of the U.S. We are a major factor in egg marketing in a majority of these states.  Many states in our market area are egg deficit regions which are areas where production of fresh shell eggs is less than total consumption.  Competition from other producers in specific market areas is generally based on price, service, and quality of product.  Strong competition exists in each of our markets.

Seasonality.  Retail sales of shell eggs are greatest during the fall and winter months and lowest during the summer months.  Prices for shell eggs fluctuate in response to seasonal demand factors and a natural increase in egg production during the spring and early summer. We generally experience lower sales and net income in our fourth and first fiscal quarters ending in May and August, respectively. During the past ten fiscal years, two of our first quarters resulted in net operating losses, and during this same period, two of our fourth quarters resulted in net operating losses.

Specialty Eggs. We produce specialty eggs such as Egg-Land’s Best®, Land O’ Lakes®, 4Grain®, and Farmhouse® branded eggs.  Specialty eggs are intended to meet the demands of consumers who are sensitive to environmental, health and/or animal welfare issues.  Specialty shell eggs are becoming a more significant segment of the shell egg market.  During our fiscal 2016 an increasing number of large restaurant chains, food service companies and grocery chains, including our largest customers, announced goals to transition to a cage-free egg supply chain by specified future dates. For fiscal 2016, specialty eggs accounted for 29.1% of our shell egg dollar sales and 22.9% of our shell egg dozens sold, as compared to 27.2% of shell egg dollar sales and 19.8% of shell egg dozens sold in fiscal 2015.  Additionally, specialty eggs sold through our co-pack arrangements accounted for an additional 2.7% of shell egg dollar sales and 2.0% of shell egg dozens sold in fiscal 2016, compared with 2.8% of shell egg dollar sales and 2.0% of shell egg dozens sold in fiscal 2015.  We produce and process Egg-Land’s Best® branded eggs under license from EB at our facilities under EB guidelines.  The product is marketed to our established base of customers at premium prices compared to non-specialty shell eggs. Egg-Land’s Best® branded eggs accounted for approximately 16.8% of our shell egg dollar sales in fiscal 2016, compared to 15.5% in fiscal 2015. Based on dozens sold, Egg-Land’s Best® branded eggs accounted for 13.6% of dozens sold for fiscal 2016, compared to 11.4% in fiscal 2015.  Land O’ Lakes® branded eggs are produced by hens that are fed a whole grain diet, with no animal fat, and no animal by-products.  Farmhouse® brand eggs are produced at our facilities by cage-free hens that are provided with a diet of all grain, vegetarian feed.  Our 4Grain® brand consists of both caged and cage-free eggs.  Farmhouse®, Land O’ Lakes®, 4Grain® and other non-Egg-Land’s Best® specialty eggs accounted for 12.3% of our shell egg dollar sales in fiscal 2016, compared to 11.7% in fiscal 2015, and 9.3% of dozens sold for fiscal 2016, compared to 8.4% for fiscal 2015.

Egg Products.  Egg products are shell eggs broken and sold in liquid, frozen, or dried form. In fiscal 2016 egg products represented approximately 4% of our net sales compared with approximately 3% in fiscal 2015.  We sell egg products primarily into the institutional and food service sectors in the U.S.  Our egg products are sold through our consolidated subsidiaries American Egg Products, LLC located in Blackshear, Georgia and Texas Egg Products, LLC located in Waelder, Texas.  Prices for egg products are directly related to Urner Barry quoted price levels.

Competition.  The production, processing, and distribution of shell eggs is an intensely competitive business, which traditionally has attracted large numbers of producers.  Shell egg competition is generally based on price, service, and product quality. 

7

The U.S. shell egg industry remains highly fragmented but is characterized by a growing concentration of producers. In 2015, 56  producers with one million or more layers owned 96% of the 291 million total U.S. layers, compared to 2000, when 63 producers with one million or more layers owned 79% of the 273 million total layers, and 1990, when 56 producers with one million or more layers owned 64% of the 232 million total layers. We believe a continuation of the concentration trend will result in reduced cyclicality of shell egg prices, but no assurance can be given in that regard. A continuation of this trend could also create greater competition among fewer producers.

Patents and Trade Names.  We own the trademarks Farmhouse®, Rio Grande®, Sunups®, Sunny Meadow® and 4Grain®. We do not own any patents or proprietary technologies. We produce and market Egg-Land's Best® and Land O’ Lakes® branded eggs under license agreements with EB.  We believe these trademarks and license agreements are important to our business.  We do not know of any infringing uses that would materially affect the use of these trademarks, and we actively defend and enforce them.

Government Regulation.  Our facilities and operations are subject to regulation by various federal, state, and local agencies, including, but not limited to, the United States Food and Drug Administration (“FDA”), USDA, Environmental Protection Agency (“EPA”), Occupational Safety and Health Administration and corresponding state agencies. The applicable regulations relate to grading, quality control, labeling, sanitary control and waste disposal. Our shell egg facilities are subject to periodic USDA, FDA and EPA inspections. Our feed production facilities are subject to FDA regulation and inspections. In addition, we maintain our own inspection program to ensure compliance with our own standards and customer specifications. We are not aware of any major capital expenditures necessary to comply with current statutes and regulations; however, there can be no assurance that we will not be required to incur significant costs for compliance with such statutes and regulations in the future.  In addition, rules are often proposed that, if adopted as proposed, could have the effect of increasing our costs. For example, in April 2016 the USDA Agricultural Marketing Service proposed rules that, if adopted, would change requirements, and increase our costs, for the production of organic eggs.

Environmental Regulation.  Our operations and facilities are subject to various federal, state, and local environmental, health and safety laws and regulations governing, among other things, the generation, storage, handling, use, transportation, disposal, and remediation of hazardous materials. Under these laws and regulations, we are required to obtain permits from governmental authorities, including, but not limited to, wastewater discharge permits. We have made, and will continue to make, capital and other expenditures relating to compliance with existing environmental, health and safety laws and regulations and permits. We are not currently aware of any major capital expenditures necessary to comply with such laws and regulations; however, because environmental, health and safety laws and regulations are becoming increasingly more stringent, including those relating to animal wastes and wastewater discharges, there can be no assurance that we will not be required to incur significant costs for compliance with such laws and regulations in the future.

Employees.  As of May 28, 2016, we had 3,277 employees, of whom 2,649 worked in egg production, processing and marketing, 178 worked in feed mill operations and 450 were administrative employees, including our executive officers.  Approximately 4.1% of our personnel are part-time.  None of our employees are covered by a collective bargaining agreement.  We consider our relations with employees to be good.

ITEM 1A. RISK FACTORS   

Our business and results of operations are subject to numerous risks and uncertainties, many of which are beyond our control.  The following is a description of the known factors that may materially affect our business, financial condition or results of operations.  They should be considered carefully, in addition to the information set forth elsewhere in this Annual Report on Form 10-K, including under Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in making any investment decisions with respect to our securities.  Additional risks or uncertainties that are not currently known to us, that we currently deem to be immaterial or that could apply to any company could also materially adversely affect our business, financial condition or results of operations.

Market prices of wholesale shell eggs are volatile and decreases in these prices can adversely impact our results of operations.

Our operating results are significantly affected by wholesale shell egg market prices, which fluctuate widely and are outside our control.  As a result, our prior performance should not be presumed to be an accurate indication of future performance. Small increases in production, or small decreases in demand, can have a large adverse effect on shell egg prices. Shell egg prices trended upward from calendar 2002 until late 2003 and early 2004 when they rose to then historical highs.  In the early fall of calendar 2004, the demand trend related to the increased popularity of high protein diets faded dramatically and prices fell.  During the time of increased demand, the egg industry geared up to produce more eggs, resulting in an oversupply of eggs.  After calendar 2006, supplies were more closely balanced with demand and egg prices again reached record levels in 2007 and 2008.  Egg prices had subsequently retreated from those record price levels due to increases in industry supply before reaching new highs in 2014.  In 2015, egg prices rose again due in part to a decrease in supply caused by the avian influenza outbreak in the upper Midwestern U.S.from April to June 2015.While the AI outbreak significantly impacted the supply and prices of eggs, there were  no positive tests for AI at any of our locations.  The average Urner-Barry Thursday prices for the large market (i.e. generic shell eggs) in the southeastern region for the months of June through November 2015 was $2.32 per dozen, with a peak of $2.97 during August.  Subsequent to November 2015, shell egg prices have declined.  Our average year to date selling price for shell eggs in fiscal 2016 of $1.735  was up 21.4% compared to fiscal 2015; however, our average selling price for the fourth quarter of fiscal 2016 of $1.152  was down 21.7% compared with the same period last year.  Market prices for shell eggs have dropped significantly from the historically high levels we experienced at the beginning of this fiscal year.  The Urner Barry price index hit a decade-low level during our fourth quarter, before recovering a portion of these declines in recent weeks.  While retail demand trends for shell eggs have been favorable, there has been demand erosion for egg products and reduced egg exports. Based on USDA reports, the laying flock is expected to increase through the end of calendar 2016, creating more supply and the potential for further price declines.  Egg prices will likely remain volatile and future prices will depend on levels of supply and the recovery of institutional demand for eggs.

Retail sales of shell eggs are greatest during the fall and winter months and lowest in the summer months. Prices for shell eggs fluctuate in response to seasonal factors and a natural increase in shell egg production during the spring and early summer. Shell egg prices tend to increase with the start of the school year and are highest prior to holiday periods, particularly Thanksgiving, Christmas and Easter. Consequently, we generally experience lower sales and net income in our first and fourth fiscal quarters ending in August and May, respectively. As a result of these seasonal and quarterly fluctuations, comparisons of our sales and operating results between different quarters within a single fiscal year are not necessarily meaningful comparisons.

A decline in consumer demand for shell eggs can negatively impact our business.

We believe fast food restaurant consumption, reports from the medical community regarding the health benefits of shell eggs, reduced shell egg cholesterol levels, high protein diet trends and industry advertising campaigns have all contributed to shell egg demand. However, there can be no assurance that the demand for shell eggs will not decline in the future. Adverse publicity relating to health concerns and changes in the perception of the nutritional value of shell eggs, as well as movement away from high protein diets, could adversely affect demand for shell eggs, which would have a material adverse effect on our future results of operations and financial condition.

Feed costs are volatile and increases in these costs can adversely impact our results of operations.

Feed cost represents the largest element of our shell egg (farm) production cost, ranging from 60% to 69% of total farm production cost in the last five fiscal years. Although feed ingredients are available from a number of sources, we have little, if any,

9

control over the prices of the ingredients we purchase, which are affected by weather, speculators, various supply and demand factors, transportation and storage costs, and agricultural and energy policies in the U.S. and internationally.  For example, the severe drought in the summer of 2012 and resulting damage to the national corn and soybean crops resulted in high and volatile feed costs.  Increases in feed costs unaccompanied by increases in the selling price of eggs can have a material adverse effect on the results of our operations.  Alternatively, low feed costs can encourage industry overproduction, possibly resulting in lower egg prices. 

Due to the cyclical nature of our business, our financial results fluctuate from year to year and between different quarters within a single fiscal year.

The shell egg industry has traditionally been subject to periods of high profitability followed by periods of significant loss. In the past, during periods of high profitability, shell egg producers have tended to increase the number of layers in production with a resulting increase in the supply of shell eggs, which generally has caused a drop in shell egg prices until supply and demand return to balance. As a result, our financial results from year to year vary significantly.  Additionally, as a result of seasonal fluctuations, our financial results fluctuate significantly between different quarters within a single fiscal year.

We purchase a portion of the shell eggs we sell from outside producers and our ability to obtain such eggs at prices and in quantities acceptable to us could fluctuate.

We produced approximately 78%  and 75% of the total number of shell eggs sold by us in 2016 and 2015, respectively, and purchased the remaining amount from outside producers. As the wholesale price for shell eggs increases, our cost to acquire shell eggs from outside producers increases. There can be no assurance that we will be able to continue to acquire shell eggs from outside producers in sufficient quantities and satisfactory prices, and our inability to do so may have a material adverse effect on our business and profitability.

Our acquisition growth strategy subjects us to various risks.

We plan to continue to pursue a growth strategy, which includes acquisitions of other companies engaged in the production and sale of shell eggs. In fiscal year 2014 we completed the purchase of our joint venture partner’s 50% interest in Delta Egg Farm, LLC; and in fiscal year 2013 we acquired the commercial egg assets of Pilgrim’s Pride Corporation and Maxim Production Co., Inc.  Acquisitions require capital resources and can divert management’s attention from our existing business. Acquisitions also entail an inherent risk that we could become subject to contingent or other liabilities, including liabilities arising from events or conduct prior to our acquisition of a business that were unknown to us at the time of acquisition. We could incur significantly greater expenditures in integrating an acquired business than we anticipated at the time of its purchase. We cannot assure you that we:

- will identify suitable acquisition candidates;

- can consummate acquisitions on acceptable terms;

- can successfully integrate an acquired business into our operations; or

- can successfully manage the operations of an acquired business.

No assurance can be given that companies acquired by us in the future will contribute positively to our results of operations or financial condition. In addition, federal antitrust laws require regulatory approval of acquisitions that exceed certain threshold levels of significance.

The consideration we pay in connection with any acquisition also affects our financial results. If we pay cash, we could be required to use a portion of our available cash to consummate the acquisition. To the extent we issue shares of our Common Stock, existing stockholders may be diluted. In addition, acquisitions may result in the incurrence of debt.

Our largest customers have historically accounted for a significant portion of our net sales volume. Accordingly, our business may be adversely affected by the loss of, or reduced purchases by, one or more of our large customers.

For the fiscal years 2016, 2015, and 2014, two customers, Wal-Mart Stores and Sam’s Clubs, on a combined basis, accounted for 28.9%,  25.7%, and 28.2% of our net sales dollars, respectively.  For fiscal years 2016, 2015, and 2014, our top ten customers accounted for 70.6%,  67.9%, and 68.5% of net sales dollars, respectively. Although we have established long-term

10

relationships with most of our customers, who continue to purchase from us based on our ability to service their needs, they are free to acquire shell eggs from other sources.  If, for any reason, one or more of our larger customers were to purchase significantly less of our shell eggs in the future or terminate their purchases from us, and we are not able to sell our shell eggs to new customers at comparable levels, it would have a material adverse effect on our business, financial condition, and results of operations.  

Failure to comply with applicable governmental regulations, including environmental regulations, could harm our operating results, financial condition, and reputation.  Further, we may incur significant costs to comply with any such regulations.

We are subject to federal, state and local regulations relating to grading, quality control, labeling, sanitary control, and waste disposal. As a fully-integrated shell egg producer, our shell egg facilities are subject to regulation and inspection by the USDA, EPA, and FDA, as well as regulation by various state and local health and agricultural agencies. All of our shell egg production and feed mill facilities are subject to FDA regulation and inspections. In addition, rules are often proposed that, if adopted as proposed, could have the effect of increasing our costs. For example, in April 2016 the USDA Agricultural Marketing Service proposed rules that, if adopted, would change requirements, and increase our costs, for the production of organic eggs.

Our operations and facilities are also subject to various federal, state and local environmental, health, and safety laws and regulations governing, among other things, the generation, storage, handling, use, transportation, disposal, and remediation of hazardous materials. Under these laws and regulations, we are also required to obtain permits from governmental authorities, including, but not limited to pollution/wastewater discharge permits.

If we fail to comply with an applicable law or regulation, or fail to obtain necessary permits, we could be subject to significant fines and penalties or other sanctions, our reputation could be harmed, and our operating results and financial condition could be materially adversely affected. In addition, because these laws and regulations are becoming increasingly more stringent, there can be no assurance that we will not be required to incur significant costs for compliance with such laws and regulations in the future.

Shell eggs and shell egg products are susceptible to microbial contamination, and we may be required to or voluntarily recall contaminated products.

Shell eggs and shell egg products are vulnerable to contamination by pathogens such as Salmonella.  Shipment of contaminated products, even if inadvertent, could result in a violation of law and lead to increased risk of exposure to product liability claims, product recalls and increased scrutiny by federal and state regulatory agencies.  In addition, products purchased from other producers could contain contaminants that may be inadvertently redistributed by us.  As such, we may decide or be required to recall a product if we or regulators believe it poses a potential health risk.  We do not maintain insurance to cover recall losses.  Any product recall could result in a loss of consumer confidence in our products, adversely affect our reputation with existing and potential customers and have a material adverse effect on our business, results of operations and financial condition.

Agricultural risks, including outbreaks of avian disease, could harm our business.

Our shell egg production activities are subject to a variety of agricultural risks. Unusual or extreme weather conditions, disease and pests can materially and adversely affect the quality and quantity of shell eggs we produce and distribute.  The Company maintains controls and procedures to reduce the risk of exposing our flocks to harmful diseases.  Despite our best efforts, outbreaks of avian disease can still occur and may adversely impact the health of our flocks.  An outbreak of avian disease could have a material adverse impact on our financial results by increasing government restrictions on the sale and distribution of our products.  Negative publicity from an outbreak within our industry can negatively impact customer perception, even if the outbreak does not directly impact our flocks.  If a substantial portion of our production facilities are affected by any of these factors in any given quarter or year, our business, financial condition, and results of operations could be materially and adversely affected.

From April through June 2015,  our industry experienced a significant avian influenza outbreak, primarily in the upper Midwestern U.S.Based on several published industry estimates, webelieve that approximately 12% of the national flock of laying hens was affected.  The affected laying hens were either destroyed by the disease or euthanized.  The effect this outbreak had on our industry and our company is discussed throughout this report.  There have been no positive tests for avian influenza at any of our locations, and we havesignificantly increased the biosecurity measures at all of our facilities; however we cannot be certain that our flocks will not be affected by AI or other diseases in the future.

11

Our business is highly competitive.

The production and sale of fresh shell eggs, which have accounted for virtually all of our net sales in recent years, is intensely competitive. We compete with a large number of competitors that may prove to be more successful than we are in marketing and selling shell eggs. We cannot provide assurance that we will be able to compete successfully with any or all of these companies. In addition, increased competition could result in price reductions, greater cyclicality, reduced margins and loss of market share, which would negatively affect our business, results of operations, and financial condition.

Pressure from animal rights groups regarding the treatment of animals may subject us to additional costs to conform our practices to comply with developing standards or subject us to marketing costs to defend challenges to our current practices and protect our image with our customers.

We and many of our customers are facing pressure from animal rights groups, such as People for the Ethical Treatment of Animals, or PETA, and the Humane Society of the United States, or HSUS, to require all companies that supply food products operate their business in a manner that treats animals in conformity with certain standards developed or approved by these animal rights groups. The standards typically require minimum cage space for hens, among other requirements, but some of these groups have made legislative efforts to ban any form of caged housing in various states.  California’s Proposition 2 and Assembly Bill 1437 was effective January 1, 2015, and did increase the cost of production in that State and for producers who sell there.  During our fiscal 2016 an increasing number of large restaurant chains, food service companies and grocery chains, including our largest customers, announced goals to transition to a cage-free egg supply chain by specified future dates.  Changing our procedures and infrastructure to conform to these types of laws or anticipated customer demand for these types of guidelines has resulted and will continue to result in additional costs to our internal production of shell eggs, including capital and operating cost increases from housing and husbandry practices and modification of existing or construction of new facilities, and the increased cost for us to purchase shell eggs from our outside suppliers. While some of the increased costs have been passed on to our customers, we cannot provide assurance that we can continue to pass on these costs, or additional costs we will face, in the future.

We are dependent on our management team, and the loss of any key member of this team may adversely affect the implementation of our business plan in a timely manner.

Our success depends largely upon the continued service of our senior management team. The loss or interruption of service of one or more of our key executive officers could adversely affect our ability to manage our operations effectively and/or pursue our growth strategy. We have not entered into any employment or non-compete agreements with any of our executive officers nor do we carry any significant key-man life insurance coverage on any such persons.  

We are controlled by the family of our founder, Fred R. Adams, Jr.

Fred R. Adams, Jr., our Founder and Chairman Emeritus, and his spouse own 27.9% of the outstanding shares of our Common Stock, which has one vote per share.  In addition, Mr. Adams and his spouse own 74.7% and his son-in-law, Adolphus B. Baker, our President, Chief Executive Officer and Chairman of the Board, and his spouse own 25.3% of the outstanding shares of our Class A Common Stock, which has ten votes per share. Mr. Baker and his spouse also own 1.4% of the outstanding shares of our Common Stock. A conservatorship has been established to manage Mr. Adams’ affairs, with his spouse and Mr. Baker as co-conservators, as a result of the impairment of Mr. Adams’ health related to his previously disclosed stroke.  Mr. Adams continues to consult actively and regularly with the Company and it is expected that he will continue to do so for as long as he is able.  As a result of the conservatorship, as of July 1, 2016, Mr. Adams, his spouse, and Mr. Baker possessed 52.4%, and Messrs. Adams and Baker and their spouses collectively possessed 66.3%, of the total voting power represented by the outstanding shares of our Common Stock and Class A Common Stock. These stockholdings include shares of our Common Stock accumulated under our employee stock ownership plan for the respective accounts of Messrs. Adams and Baker and Mr. Baker’s spouse.

The Adams and Baker families intend to retain ownership of a sufficient amount of Common Stock and Class A Common Stock to assure continued ownership of over 50% of the voting power of our outstanding shares of capital stock. Such ownership will make an unsolicited acquisition of the Company more difficult and discourage certain types of transactions involving a change of control of our Company, including transactions in which the holders of Common Stock might otherwise receive a premium for their shares over then current market prices. In addition, certain provisions of our Certificate of Incorporation require that our Class A Common Stock be issued only to Fred R. Adams, Jr. and members of his immediate family, and if shares of our Class A Common Stock, by operation of law or otherwise, are deemed not to be owned by Mr. Adams or a member of his immediate family, the voting

12

power of any such shares shall be automatically reduced to one vote per share. The Adams and Baker families’ controlling ownership of our capital stock may adversely affect the market price of our Common Stock.

Based on the Adams family’s beneficial ownership of our outstanding capital stock, we are a “controlled company,” as defined in Rule 5615(c)(1) of the NASDAQ’s listing standards. Accordingly, we are exempt from certain requirements of NASDAQ’s corporate governance listing standards, including the requirement to maintain a majority of independent directors on our board of directors and the requirements regarding the determination of compensation of executive officers and the nomination of directors by independent directors. 

Current and any future litigation could expose us to significant liabilities and adversely affect our business reputation.

We and certain of our subsidiaries are involved in various legal proceedings.  Litigation is inherently unpredictable, and although we believe we have meaningful defenses in these matters, we may incur judgments or enter into settlements of claims that could have a material adverse effect on our results of operations, cash flow and financial condition.  For a discussion of legal proceedings see Item 3 below.  Such lawsuits are expensive to defend, divert management’s attention, and may result in significant judgments or settlements.  Legal proceedings may expose us to negative publicity, which could adversely affect our business reputation and customer preference for our products and brands.

Impairment in the carrying value of goodwill or other assets could negatively affect our results of operations or net worth.

Goodwill represents the excess of the cost of business acquisitions over the fair value of the identifiable net assets acquired.  Goodwill is reviewed at least annually for impairment by assessing qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  As of May 28, 2016, we had $29.2 million of goodwill.  While we believe the current carrying value of this goodwill is not impaired, any future goodwill impairment charges could materially adversely affect our results of operations in any particular period or our net worth.

The loss of any registered trademark or other intellectual property could enable other companies to compete more effectively with us.

We utilize intellectual property in our business.  For example, we own the trademarks Farmhouse®,  Rio Grande®,  Sunups®,  Sunny Meadow® and 4Grain®.  We also produce and market Egg-Land’s Best® and Land O’ Lakes® under license agreements with EB.  We have invested a significant amount of money in establishing and promoting our trademarked brands.  The loss or expiration of any intellectual property could enable other companies to compete more effectively with us by allowing our competitors to make and sell products substantially similar to those we offer.  This could negatively impact our ability to produce and sell the associated products, thereby adversely affecting our operations.

Extreme weather, natural disasters or other events beyond our control could negatively impact our business.

Fire, bioterrorism, pandemic, extreme weather or natural disasters, including droughts, floods, excessive cold or heat, hurricanes or other storms, could impair the health or growth of our flocks, production or availability of feed ingredients, or interfere with our operations due to power outages, fuel shortages, discharges from overtopped or breached wastewater treatment lagoons, damage to our production and processing facilities or disruption of transportation channels, among other things. Any of these factors could have a material adverse effect on our financial results.

Failure of our information technology systems or software, or a security breach of those systems, could adversely affect our day-to-day operations and decision making processes and have an adverse effect on our performance.

The efficient operation of our business depends on our information technology systems. We rely on our information technology systems to effectively manage our business data, communications, logistics, accounting and other business processes. If we do not allocate and effectively manage the resources necessary to build and sustain an appropriate technology environment, our business or financial results could be negatively impacted. In addition, our information technology systems may be vulnerable to damage or interruption from circumstances beyond our control, including systems failures, viruses, security breaches or cyber incidents such as intentional cyber-attacks aimed at theft of sensitive data or inadvertent cyber-security compromises.

13

A security breach of such information could result in damage to our reputation, and could negatively impact our relations with our customers or employees. Any such damage or interruption could have a material adverse effect on our business.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 2.  PROPERTIES

We operate farms, processing plants, hatcheries, feed mills, warehouses, offices and other properties located in Alabama, Arkansas, Florida, Georgia, Kansas, Kentucky, Louisiana, Mississippi, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Texas and Utah. As of May 28, 2016, the facilities included three breeding facilities, two hatcheries, three wholesale distribution centers, 21 feed mills, 44 shell egg production facilities, 26 pullet growing facilities, and 41 processing and packing facilities.  We own significant interests in two companies that own egg products facilities, which are consolidated in our financial statements. Most of our operations are conducted from properties we own.

As of May 28, 2016, we owned approximately 29,145 acres of land in various locations throughout our geographic market area. We have the ability to hatch 21.2 million pullet chicks annually, grow 25.3 million pullets annually, house 40.8 million laying hens, and control the production of 38.3million layers, with the remainder controlled by contract growers. We own mills that can produce 744 tons of feed per hour, and processing facilities capable of processing 14,260 cases of shell eggs per hour (with each case containing 30 dozen shell eggs).

Over the past five fiscal years, our capital expenditures, excluding acquisitions of shell egg production and processing facilities from others, have totaled an aggregate amount of approximately $270.7 million. 

ITEM 3.  LEGAL PROCEEDINGS

Egg Antitrust Litigation

Since September 25, 2008, the Company has been named as one of several defendants in numerous antitrust cases involving the United States shell egg industry.  In some of these cases, the named plaintiffs allege that they purchased eggs or egg products directly from a defendant and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.  In other cases, the named plaintiffs allege that they purchased shell eggs and egg products directly from one or more of the defendants but sue only for their own alleged damages and not on behalf of a putative class.  In the remaining cases, the named plaintiffs are individuals or companies who allege that they purchased shell eggs indirectly from one or more of the defendants – that is, they purchased from retailers that had previously purchased from defendants or other parties – and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.

The Judicial Panel on Multidistrict Litigation consolidated all of the putative class actions (as well as certain other cases in which the Company was not a named defendant) for pretrial proceedings in the United States District Court for the Eastern District of Pennsylvania. The Pennsylvania court has organized the putative class actions around two groups (direct purchasers and indirect purchasers) and has named interim lead counsel for the named plaintiffs in each group. 

The Direct Purchaser Putative Class Action. The direct purchaser putative class 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.  As previously reported, in November 2014, the Court approved the Company’s settlement with the direct purchaser plaintiff class and entered final judgment dismissing with prejudice the class members’ claims against the Company.  

The Indirect Purchaser Putative Class Action.  The indirect purchaser putative class 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.  On April 20-21, 2015, the Court held an evidentiary hearing on the indirect purchaser plaintiffs’ motion for class certification. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of the entire case or, in the alternative, dismissal of portions of the case.  On July 2, 2015, the indirect purchaser plaintiffs filed motions for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal and state antitrust laws. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions. On September 18, 2015, the Court denied the indirect purchaser plaintiffs’ motion for class certification

14

of 21 separate classes seeking damages under the laws of 21 states, holding that the plaintiffs were not able to prove that their purported method for ascertaining class membership was reliable or administratively feasible, that common questions would predominate, or that their proposed class approach would be manageable in a single trial.  In addition to barring any right to pursue a class monetary remedy under state law, the Court also denied indirect purchaser plaintiffs’ request for certification of an injunctive-relief class under federal law.  However, the court allowed the indirect purchaser plaintiffs to renew their motion for class certification seeking a federal injunction.  The plaintiffs filed their renewed motion to certify an injunctive-relief class on October 23, 2015.  The Company joined the other defendants in opposing that motion on November 20.  The plaintiffs filed their reply memorandum on December 11, 2015. The plaintiffs requested oral argument on their renewed motion for injunctive class certification.  The plaintiffs also filed a petition with the United States Court of Appeals for the Third Circuit, asking the court to hear an immediate appeal of the trial court’s denial of the motion to certify 21 state-law damages classes.  On December 3, 2015, the Third Circuit entered an order staying its consideration of the plaintiffs’ request for an immediate appeal of the damages-class ruling pending the trial court’s resolution of the plaintiffs’ renewed motion to certify an injunctive-relief class. 

The Non-Class Cases. Six of the cases in which plaintiffs do not seek to certify a class have been consolidated with the putative class actions 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 court granted with prejudice the defendants’ renewed motion to dismiss the non-class plaintiffs’ claims for damages arising before September 24, 2004. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of all of the claims in all of these cases or, in the alternative, dismissal of portions of these cases.  On July 2, 2015, the non-class plaintiffs filed a motion for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal antitrust law. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions.

 Allegations in Each Case. In all of the cases described above, the plaintiffs allege that the Company and certain other large domestic egg producers conspired to reduce the domestic supply of eggs in a concerted effort to raise the price of eggs to artificially high levels.  In each case, plaintiffs allege that all defendants agreed to reduce the domestic supply of eggs by: (a) agreeing to limit production; (b) manipulating egg exports; and (c) implementing industry-wide animal welfare guidelines that reduced the number of hens and eggs. 

The named plaintiffs in the remaining indirect purchaser putative class action seek treble damages under the statutes and common-law of various states and injunctive relief under the Sherman Act on behalf of themselves and all other putative class members in the United States. Although plaintiffs allege a class period starting in October2006 and running “through the present,” the Court denied the plaintiffs’ motion to certify classes seeking damages under the laws of 21 states and denied without prejudice the plaintiffs’ motion to certify an injunctive-relief class, although the plaintiffs have filed a renewed motion to certify an injunctive-relief class, as discussed above. 

Five of the original six non-class cases remain pending against the Company.  The principal plaintiffs in these cases are: The Kroger Co.; Publix Super Markets, Inc.; SUPERVALU, Inc.; Safeway, Inc.; Albertsons LLC; H.E. Butt Grocery Co.; The Great Atlantic & Pacific Tea Company, Inc.; Walgreen Co.; Hy-Vee, Inc.; Kraft Food Global, Inc., General Mills, Inc., Nestle USA, Inc., and The Kellogg Company.In four of these remaining non-class cases, the plaintiffs seek treble damages and injunctive relief under the Sherman Act.  In the fifth remaining non-class case, the plaintiff seeks treble damages and injunctive relief under the Sherman Act and the Ohio antitrust act (known as the Valentine Act). 

The Pennsylvania court has entered a series of orders related to case management, discovery, class certification, summary judgment, and scheduling.  The Pennsylvania court has not set a trial date for any of the Company’s remaining consolidated cases (non-class and indirect purchaser cases).

The Company intends to continue to defend the remaining cases 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 these cases.  Accordingly, adjustments, if any, which might result from the resolution of these remaining legal matters, have not been reflected in the financial statements.

State of Oklahoma Watershed Pollution Litigation

On June 18, 2005, the State of Oklahoma filed suit, in the United States District Court for the Northern District of Oklahoma, against Cal-Maine Foods, Inc. and Tyson Foods, Inc. and affiliates, Cobb-Vantress, Inc., Cargill, Inc. and its affiliate, George’s, Inc. and its affiliate, Peterson Farms, Inc. and Simmons Foods, Inc. The State of Oklahoma claims that through the disposal of chicken litter the defendants have polluted the Illinois River Watershed. This watershed provides water to eastern Oklahoma. The complaint seeks injunctive relief and monetary damages, but the claim for monetary damages has been dismissed by the court. Cal-Maine Foods, Inc. discontinued operations in the watershed. Accordingly, we do not anticipate that Cal-Maine Foods, Inc. will be materially affected by the request for injunctive relief unless the court orders substantial affirmative remediation. Since the litigation began, Cal-Maine Foods, Inc. purchased 100% of the membership interests of Benton County Foods, LLC, which is an ongoing commercial shell egg operation within the Illinois River Watershed. Benton County Foods, LLC is not a defendant in the litigation.

The trial in the case began in September 2009 and concluded in February 2010. The case was tried to the court without a jury and the court has not yet issued its ruling. Management believes the risk of material loss related to this matter to be remote.

Florida Civil Investigative Demand

On November 4, 2008, the Company received an antitrust civil investigative demand from the Attorney General of the State of Florida. The demand seeks production of documents and responses to interrogatories relating to the production and sale of eggs and egg products. The Company is cooperating with this investigation and has, on three occasions, entered into an agreement with the State of Florida tolling the statute of limitations applicable to any supposed claims the State is investigating. No allegations of wrongdoing have been made against the Company in this matter.

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.

At this time, it is not possible for us to predict the ultimate outcome of the matters set forth above.

Dividends 

Cal-Maine has a dividend policy adopted by its Board of Directors.  Pursuant to the policy, Cal-Maine 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 65th 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 Company’s loan agreements provide that unless otherwise approved by its lenders, the Company must limit dividends paid in any quarter to not exceed an amount equal to one-third of the previous quarter’s consolidated net income, which dividends are allowed to be paid if there are no events of default.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

RISK FACTORS; FORWARD-LOOKING STATEMENTS

For information relating to important risks and uncertainties that could materially adversely affect our business, securities, financial condition or operating results, reference is made to the disclosure set forth under Item 1A above under the caption “Risk Factors.” In addition, because the following discussion includes numerous forward-looking statements relating to us, our results of operations, financial condition and business, reference is made to the information set forth in the section of Part I immediately preceding Item 1 above under the caption “Forward-Looking Statements.”

OVERVIEW

Cal-Maine Foods, Inc. (“we,” “us,” “our,” or the “Company”) is primarily engaged in the production, grading, packaging, marketing and distribution of fresh shell eggs. Our fiscal year end is the Saturday nearest to May 31 which was May 28, 2016 (52 weeks),  May 30, 2015 (52 weeks), and May31, 2014 (52 weeks) for the most recent three fiscal years.

Our operations are fully integrated.  We hatch chicks, grow and maintain flocks of pullets (young female chickens, under 18 weeks of age), layers (mature female chickens) and breeders (male and female birds used to produce fertile eggs to be hatched for egg production flocks), manufacture feed, and produce, process and distribute shell eggs. We are the largest producer and marketer of shell eggs in the U.S.  We market the majority of our shell eggs in the southwestern, southeastern, mid-western, and mid-Atlantic regions of the U.S.  We market our shell eggs through our extensive distribution network to a diverse group of customers, including national and regional grocery store chains, club stores, foodservice distributors, and egg product consumers.

Our operating results are directly tied to egg prices, which are highly volatile and subject to wide fluctuations, and are outside of our control. For example, the annual average Urner-Barry Southeastern Regional Large Egg Market Price per dozen eggs, for our fiscal 2005-2016 ranged from a low of $0.72 during fiscal 2005 to a high of $2.97 during fiscal 2016.  The shell egg industry has traditionally been subject to periods of high profitability followed by periods of significant loss. In the past, during periods of high profitability, shell egg producers tended to increase the number of layers in production with a resulting increase in the supply of shell eggs, which generally caused a drop in shell egg prices until supply and demand returned to balance.  As a result, our financial results from year to year may vary significantly.   Shorter term, retail sales of shell eggs historically have been greatest during the fall and winter months and lowest during the summer months.  Our need for working capital generally is highest in the last and first fiscal quarters ending in May and August, respectively, when egg prices are normally at seasonal lows.   Prices for shell eggs fluctuate in response to seasonal factors and a natural increase in shell egg production during the spring and early summer.  Shell egg prices tend to increase with the start of the school year and are highest prior to holiday periods, particularly Thanksgiving, Christmas, and Easter.  Consequently, we generally experience lower sales and net income in our first and fourth fiscal quarters ending in August and May, respectively. Because of the seasonal and quarterly fluctuations, comparisons of our sales and operating results between different quarters within a single fiscal year are not necessarily meaningful comparisons.

From April through June 2015, our industry experienced a significant avian influenza (“AI”) outbreak, primarily in the upper Midwestern U.S.  Based on several published industry estimates, we believe approximately 12% of the national flock of laying hens was affected.  The affected laying hens were either destroyed by the disease or euthanized.  During April through June 2015, the supply of laying hens decreased substantially, and then began to recover gradually. As of June 1, 2016, the national laying hen flock according to the U.S. Department of Agriculture was approximately 10.2% higher than the AI reduced flock from June 1, 2015, but remained 1.6% below the number of layers on June 1, 2014.  Egg prices increased significantly during the summer and fall of 2015. The average Urner-Barry Thursday prices for the large market (i.e. generic shell eggs) in the southeastern region for the months of June through November 2015 was $2.32 per dozen, with a peak of $2.97 in August.  Subsequent to November 2015, shell egg prices declined.  Our average year to date selling price for shell eggs in fiscal 2016 of $1.735 was up 21.4% compared to fiscal 2015; however, our average selling price for the fourth quarter of fiscal 2016 of $1.152 was down 21.7% compared with the same period last year.  The Urner Barry price index hit a decade-low level during our fourth quarter, before recovering a portion of this decline in recent weeks.Accordingly, our net average selling prices for eggs for each of our four quarters in fiscal 2016 was particularly volatile:  $2.243, $1.970, $1.568 and $1.152 for our first through fourth quarters of fiscal 2016, respectively, compared to $1.354, $1.379, $1.503 and $1.471 for our first through fourth quarters of fiscal 2015, respectively.  While retail demand trends for shell eggs have been favorable, there has been demand erosion for egg products and reduced egg exports. Based on USDA reports, the laying flock is expected to increase through the end of calendar 2016, creating more supply and the potential for further price declines. Egg prices will likely remain volatile and future prices will depend on levels of supply and the recovery of institutional

20

demand for eggs which was adversely impacted as a result of the 2015 shortages caused by AI.  There have been no positive tests for AI at any of our locations, and we have significantly increased the biosecurity measures at all of our facilities; however, we cannot be certain our flocks will not be affected by AI or other diseases in the future.

We are one of the largest producers and marketers of value-added specialty shell eggs in the U.S. For accounting and tax purposes, we classify nutritionally enhanced, cage-free, organic and brown eggs as specialty shell eggs. They have been a significant and growing segment of the market in recent years. During our fiscal 2016 an increasing number of large restaurant chains, food service companies and grocery chains, including our largest customers, announced goals to transition to a cage-free egg supply chain by specified future dates. We are working with our customers to achieve smooth progress in meeting their goals, and have been making and expect to continue to make significant investments in new and remodeled facilities to meet this demand, including through our Red River joint venture discussed below.

For fiscal 2016, we produced approximately 78% of the total number of shell eggs sold by us, with approximately 4% of such shell egg production provided by contract producers. Contract producers utilize their facilities to produce shell eggs from layers owned by us. We own the shell eggs produced under these arrangements. For fiscal 2016, approximately 22% of the total number of shell eggs sold by us were purchased from outside producers for resale.

Our cost of production is materially affected by feed costs, which are highly volatile and subject to wide fluctuation.  For fiscal 2016, feed costs averaged about 60% of our total farm egg production cost.  Changes in market prices for corn and soybean meal, the primary ingredients in the feed we use, result in changes in our cost of goods sold.   For our last five fiscal years, average feed cost per dozen sold ranged from a low of $0.41 in fiscal 2016 to a high of $0.54 in fiscal 2013.  The cost of our primary feed ingredients, which are commodities, are subject to factors over which we have little or no control such as volatile price changes caused by weather, size of harvest, transportation and storage costs, demand and the agricultural and energy policies of the U.S. and foreign governments. The large 2015 crops increased available supplies for corn and soybean meal which favorably impacted our results for fiscal 2016, compared to the same period of fiscal 2015.  Increased U.S. acreage for both corn and soybeans in 2016 should provide adequate domestic supplies for both of our primary feed ingredients.  Domestic corn supplies could be particularly robust, although domestic soybean stocks could be negatively impacted by increased exports due to reduced supplies from South America.

During the fourth quarter of fiscal 2015, the Company entered into the Red River Valley Egg Farm, LLC (“Red River”) joint venture with Rose Acre Farms, Inc.  Construction of the state of the art shell egg production complex near Bogata, Red River County, Texas is nearing completion.  The first flock was placed in November 2015 and we expect the complex to be completely stocked in early calendar 2017.  The plans for the complex provide capacity for approximately 1.8 million cage-free laying hens.  In fiscal 2016 we incurred $34.0 million of construction and startup costs associated with the joint venture.

The acquisition of our joint venture partner’s 50% interest in Delta Egg Farm, LLC (“Delta Egg”) as described in Note 2 of the Notes to the Consolidated Financial Statements is referred to below as the “Acquisition”.  Our fiscal 2016, 2015 and 2014 financial results include the operations of Delta Egg beginning March 1, 2014.  Prior to March 1, 2014, our 50% interest in the earnings of Delta Egg was included in equity in earnings of affiliates under the equity method of accounting.

We effected a 2-for-1 stock split for shares of our common stock and Class A common stock in October 2014, and all per share amounts in this report have been adjusted as necessary to reflect the split.

Executive Overview of Results – May 28, 2016,  May 30, 2015, and May31, 2014

Our operating results are significantly affected by wholesale shell egg market prices and feed costs, which can fluctuate widely and are outside of our control.  The majority of our shell eggs are sold at prices related to the Urner Barry Spot Egg Market Quotations for the southeastern and southcentral regions of the country, or formulas related to our costs of production which include the cost of corn and soybean meal.  The following table shows our net income, net average shell egg selling price, feed cost per dozen produced, and the average Urner Barry wholesale large shell egg prices in the southeast region, for each of our three most recent fiscal years.

_{1- Average Thursday price for the large market (i.e. generic shell eggs) in the southeastern region}

The shell egg industry has traditionally been subject to periods of high profitability followed by periods of significant loss. The periods of high profitability have often reflected increased consumer demand relative to supply while the periods of significant loss have often reflected excess supply for the then prevailing consumer demand.  Historically, demand for shell eggs increases in line with overall population growth. As reflected above, our operating results fluctuate with changes in the spot egg market quote and feed costs.   The net average shell egg selling price is the blended price for all sizes and grades of shell eggs, including non-graded shell egg sales, breaking stock and undergrades.  In fiscal 2014 and 2015,our average net selling price increased, reflecting strong demand for shell eggs across our markets, and feed costs decreased each year over the previous year.  In fiscal 2016, our net average selling price increased over the previous year primarily due to supply constraints during much of our fiscal year resulting from the AI outbreak, and feed costs decreased.  Gross profit and net income for fiscal 2016 increased significantly compared to the prior year, primarily due to increased selling prices and a decrease in feed costs.

Fiscal Year Ended May 28, 2016 Compared to Fiscal Year Ended May 30, 2015

NET SALES

In fiscal 2016, approximately 96% of our net sales consisted of shell eggs and approximately 4% was egg products.  Net sales for the fiscal year ended May 28, 2016 were $1,908.7 million, an increase of $332.6 million, or 21.1%, from net sales of $1,576.1 million for fiscal 2015.  In fiscal 2016 total dozens of eggs sold decreased and egg selling prices increased as compared to fiscal 2015. In fiscal 2016 total dozens of shell eggs sold were 1,053.6 million, a decrease of 9.5 million dozen, or  0.9%, compared to 1,063.1 million sold in fiscal 2015 resulting in a decrease in net sales of $13.6 million for fiscal 2016 compared with the prior year which we believe was primarily due to supply constraints and higher prices resulting from the AI outbreak.  Our average selling price of shell eggs increased from $1.429 per dozen for fiscal 2015 to $1.735 per dozen for fiscal 2016, an increase of $0.306 per dozen, or 21.4%, primarily reflecting higher egg prices resulting from the AI outbreak and a higher percentage of specialty egg sales.  The increase in sales price in fiscal 2016 over 2015 resulted in a corresponding increase in net sales of $325.1 million.  The remainder of our increase in sales over the prior fiscal year not related to shell egg volume or prices was the result of increased sales from egg products which is discussed later in this section.  Our operating results are significantly affected by wholesale shell egg market prices, which are outside of our control. Small changes in production or demand levels can have a large effect on shell egg prices. 

The table below represents an analysis of our non-specialty and specialty, as well as co-pack specialty, shell egg sales.  Following the table is a discussion of the information presented in the table.

Non-specialty shell eggs include all shell egg sales not specifically identified as specialty or co-pack specialty shell egg sales.   This market is characterized generally by an inelasticity of demand, and small increases in production or decreases in demand can have a large adverse effect on prices and vice-versa.  In fiscal 2016, non-specialty shell eggs represented approximately 67.7% of our shell egg revenue, compared to 69.2% for fiscal 2015.   Sales of non-specialty shell eggs accounted for approximately 75.1% and 78.1% of total shell egg volumes in fiscal 2016 and 2015, respectively.

For the thirteen-week period ended May 28, 2016, non-specialty shell eggs represented approximately 55.6% of our shell egg revenue, compared to 68.5% for the thirteen-week period ended May 30, 2015, reflecting the large decrease in net average selling price for non-specialty eggs during the current period compared to the same period of last year.   For the thirteen-week period

23

ended May 28, 2016, non-specialty shell eggs accounted for approximately 75.0% of the total shell egg volume, compared to 77.1% for the comparable period of 2015.

Specialty eggs, which include nutritionally enhanced, cage-free, organic and brown eggs, continued to make up a larger portion of our total shell egg revenue and dozens in fiscal 2016.  For fiscal 2016, specialty eggs accounted for 29.1% of shell egg revenue, compared to 27.2% in fiscal 2015, and 22.9% of shell egg volume in fiscal 2016, compared to 19.8% in fiscal 2015.  Additionally, for fiscal 2016, specialty eggs sold through co-pack arrangements accounted for 2.7% of shell egg revenue, compared to 2.8% in fiscal 2015, and 2.0% of shell egg volume in fiscal 2016 and 2015.  Specialty egg retail prices are less cyclical than non-specialty shell egg prices and are generally higher due to consumer willingness to pay for the perceived increased benefits from these products. This effect was particularly evident in our fourth fiscal quarter of 2016, as non-specialty egg prices declined more than specialty egg prices. However, as non-specialty egg prices have declined, we are experiencing some margin and volume pressures on specialty egg sales.

For the thirteen-week period ended May 28,  2016, specialty shell eggs and specialty shell eggs sold through co-pack arrangements represented approximately 40.2% and 3.1%, of our shell egg revenue, compared to 28.2% and 2.6%, respectively, for the comparable period offiscal 2015.   As previously discussed, selling prices for non-specialty eggs decreased during the current period resulting in a larger percentage of our shell egg sales being attributable to the less cyclical specialty shell eggs.  For the thirteen-week period ended May 28, 2016, specialty shell eggs and specialty shell eggs sold through co-pack arrangements accounted for approximately 23.3% and 1.7% of the total shell egg volume, compared to 21.0% and 1.9%, respectively, for the comparable period of fiscal 2015.

As discussed above, while egg prices increased substantially after the AI outbreak during the early part of our fiscal 2016, egg prices declined to a decade-low level during our fourth quarter, and were 21.7 percent lower than our average selling price in our fiscal 2015 fourth quarter.  Based on USDA reports, the laying flock is expected to increase through the end of calendar 2016, creating more supply and the potential for further price declines.  In addition, our sales for the fourth quarter reflect lower volumes primarily related to the loss of a portion of a major customer’s co-pack business. We expect this change to have a negative impact on our fiscal 2017 dozens sold and revenue although the impact on our margins would be lower.

The shell egg sales classified as “Other sales” represent hard cooked eggs, hatching eggs, other egg products, hens, and manure, which are included with our shell egg operations.

Egg products are shell eggs that are broken and sold in liquid, frozen, or dried form.  Our egg products are sold through our consolidated subsidiaries American Egg Products, LLC (“AEP”) and Texas Egg Products, LLC (“TEP”).  For fiscal 2016 egg product sales were $70.7 million, an increase of $25.3 million, or 55.7%, compared to $45.4 million for fiscal 2015.  Egg products volume for fiscal 2016 was 58.5 million pounds, anincrease of 7.5 million pounds, or 14.7%, compared to 51.0 million pounds for fiscal 2015.  The increases in our sales volume and market prices for egg products in the current fiscal year were due to a shortage of supply from the AI affected locations of other producers, as the AI outbreak had a disproportionately large impact on suppliers of egg products.  In fiscal 2016, the selling price per pound was $1.213 compared to $0.891 for fiscal 2015, an increase of 36.1%.

Cost of sales for the fiscal year ended May 28, 2016was $1,260.6 million, an increase of $80.2 million, or 6.8%, compared to $1,180.4 million for fiscal 2015.  Comparing fiscal 2016 to fiscal 2015, dozens produced and average cost per dozen purchased from outside shell egg producers increasedwhile cost of feed ingredients decreased.  This fiscal year we produced 77.8% of the eggs sold by us, as compared to 75.1% for the previous year. Feed cost for fiscal 2016 was $0.414 per dozen, compared to $0.439 per dozen for the prior fiscal year, a decrease of 5.7%.  The decrease in feed cost per dozen resulted in a decrease in cost of sales of $20.6 million for fiscal 2016 compared with 2015. 

For the thirteen weeks ended May 28, 2016, compared to the same period of 2015, cost of sales decreased from $293.6 million in the fourth quarter of fiscal 2015, to $262.3 million in the current period.  This decrease of $31.3 million, or 10.7%, was primarily the result of decreased cost of outside egg purchases from $1.43 per dozen in the fourth quarter of fiscal 2015 to $1.11 in the comparable period of fiscal 2016.  Feed cost per dozen for the fourth quarter of fiscal 2016 was $0.396, compared to $0.406 for the same quarter of fiscal 2015, a decrease of 2.5%.

Gross profit increased from 25.1% of net sales for fiscal 2015, to 34.0% of net sales for fiscal 2016.  The improvement is the result of lower feed costs and increased egg selling prices.

OPERATING INCOME

As a result of the above, our operating income was $470.3 million for fiscal 2016, compared to $235.3 million for fiscal 2015.  Operating income as a percent of net saleswas 24.7% and 14.9% for fiscal 2016 and 2015, respectively. 

OTHER INCOME (EXPENSE)

Total other income (expense) consists of income (expenses) not directly charged to, or related to, operations such as interest expense, interest income, royalty income, patronage dividends, and equity in earnings of affiliates, among other items. Total other income for fiscal 2016 was $16.9 million compared to $11.2 million for fiscal 2015.  As a percent of net sales, total other income was 0.9% for fiscal 2016, compared to 0.7% for fiscal 2015.

Net interest income for fiscal 2016 was $3.2 million compared to net interest expense of $515,000 for fiscal 2015.  Interest income from available for sale securities increased due to higher average invested balances and higher rates of return. The reduction of interest expense resulted from the Company reducing outstanding debt.

26

Equity in income of affiliates for fiscal 2016 was $5.0 million compared to $2.7 million for fiscal 2015.  The increase of $2.3 million is primarily due to our interest in the Southwest Specialty Egg, LLC joint venture as well as increased income from specialty egg sales and patronage dividends in our other unconsolidated specialty egg joint ventures.

INCOME TAXES

For the fiscal year ended May 28, 2016, our pre-tax income was $487.2 million, compared to $246.5 million for fiscal 2015. Income tax expense of $169.2 million was recorded for fiscal 2016 with an effective income tax rate of 34.8%, compared to $84.3 million for fiscal 2015 with an effective income tax rate of 34.3%.

Items causing our effective rate to differ from the federal statutory income tax rate of 35% are state income taxes and certain items included in income or loss for financial reporting purposes that are not included in taxable income or loss for income tax purposes, including tax exempt interest income, the domestic manufacturers deduction, and net income or loss attributable to noncontrolling interest.

NET INCOME ATTRIBUTABLE TO NONCONTROLLING INTEREST

Net income attributable to noncontrolling interest in AEP and TEP for fiscal 2016 was $2.0 million as compared to $1.0 million for fiscal 2015.

NET INCOME ATTRIBUTABLE TO CAL-MAINE FOODS, INC.

As a result of the above, net income for fiscal 2016 was $316.0 million, or $6.56 per basic share and $6.53 per diluted share, compared to $161.3 million, or $3.35 per basic share and $3.33 per diluted share for fiscal 2015. 

Fiscal Year Ended May 30, 2015 Compared to Fiscal Year Ended May 31, 2014

NET SALES

In fiscal 2015, approximately 97% of our net sales consisted of shell eggs and approximately 3% was egg products.  Net sales for the fiscal year ended May 30, 2015 were $1,576.1 million, an increase of $135.2 million, or 9.4%, from net sales of $1,440.9 million for fiscal 2014.  In fiscal 2015 total dozens of eggs sold increased and egg selling prices increased as compared to fiscal 2014. In fiscal 2015 total dozens of shell eggs sold were 1,063.1 million, an increase of 49.4 million dozen, or 4.9%, compared to 1,013.7 million sold in fiscal 2014. This increase in volume resulted in an increase in net sales of $67.3 million for fiscal 2015 compared with the prior year.  Our average selling price of shell eggs increased from $1.362 per dozen for fiscal 2014 to $1.429 per dozen for fiscal 2015, an increase of $0.067 per dozen, or 4.9%, reflecting strong demand for shell eggs across our markets and a higher percentage of specialty egg sales.  The increase in sales price in fiscal 2015 over 2014 resulted in a corresponding increase in net sales of $71.2 million.  Our operating results are significantly affected by wholesale shell egg market prices, which are outside of our control. Small changes in production or demand levels can have a large effect on shell egg prices.

Selling, general and administrative expenses, which include costs of marketing, distribution, accounting and corporate overhead, were $160.4 million in fiscal 2015, an increase of $3.7 million, or 2.3%, compared to $156.7 million for fiscal 2014.  Stock compensation expense increased $1.2 million for the current fiscal year.  Stock compensation expense is dependent on the closing price of the Company’s Common Stock.  For our stock compensation arrangements classified as equity awards (e.g. restricted stock), we recognized stock compensation expense ratably over the vesting period.  For our stock compensation arrangements classified as liability awards, we recognize increases or decreases in the value of such awards as increases or decreases, respectively, to stock compensation expense. For additional information, see Note 11 to  Notes to Consolidated Financial Statements.  The increase in specialty egg expense for fiscal 2015 compared to fiscal 2014 is attributable to a 20.8% increase in specialty shell egg dozens sold resulting in an increase in advertising promotions and franchise expense.  As a percentage of net sales, payroll and overhead is 2.0% for fiscal 2015 and fiscal 2014. Other expenses, which include expenses for repairs, professional fees, and insurance, decreased for fiscal 2015 compared with fiscal 2014 as a result of a 2014 confidential legal settlement and related legal fees as well as decreases in other tax expense.  During fiscal 2015 we recognized $239,000 in expense resulting from the increase in fair value of contingent consideration applicable to acquisitions, compared to $4.4 million in fiscal 2014, both of which are reflected in other expenses.   See Note 15   to Notes to Consolidated Financial Statements for additional information.  As a percentage of net sales, delivery expense is 3.0% for fiscal 2015 and fiscal 2014.  As a percent of net sales, selling, general and administrative expense decreased from 10.9% in fiscal 2014 to 10.2% in fiscal 2015.

Selling, general, and administrative expense was $42.8 million for the thirteen-week period ended May 30, 2015, a decrease of $919,000, or 2.1%, compared to $43.8 million for the thirteen-week period ended May 31, 2014.  Other expenses for the thirteen-week period ended May 30, 2015, decreased $2.8 million, or 29.7%, compared to the same period of fiscal 2014, primarily as a result of the previously discussed decrease in expense resulting from the fair value of contingent consideration on our acquisition of Maxim as well as a decrease in other tax expense.  This decrease is partially offset by the increase in specialty egg expense for the thirteen-week period ended May 30, 2015 compared to the same period of fiscal 2014 which is attributable to a 19.3% increase specialty shell egg dozens sold resulting in an increase in advertising promotions and franchise expense.

OPERATING INCOME

As a result of the above, our operating income was $235.3 million for fiscal 2015, compared to $146.1 million for fiscal 2014.  Operating income as a percent of net sales for fiscal 2015 was 14.9%, compared to 10.1% for fiscal 2014. 

OTHER INCOME (EXPENSE)

Total other income (expense) consists of income (expenses) not directly charged to, or related to, operations such as interest expense, royalty income, and patronage income, equity in earnings of affiliates, among other items. Total other income for fiscal 2015 was $11.2 million compared to $15.8 million for fiscal 2014.  As a percent of net sales, total other income was 0.7% for fiscal 2015, compared to 1.12% for fiscal 2014.

Other income, net, decreased from $8.8 million in fiscal 2014 to $2.2 million in fiscal 2015 primarily due to a fiscal 2014 non-taxable, non-cash gain of $4.0 million for the remeasurement of our equity interest in Delta Egg to the fair value in connection with the purchase of our joint venture partner’s 50% membership interest on March 1, 2014, as well as a $1.4 million decrease in royalty income related to oil and gas wells located on property we own in Texas.  For additional information see Note 2 to Notes to Consolidated Financial Statements.

INCOME TAXES

For the fiscal year ended May 30, 2015, our pre-tax income was $246.5 million, compared to $161.8 million for fiscal 2014.  Income tax expense of $84.3 million was recorded for fiscal 2015 with an effective income tax rate of 34.3%, compared to $52.0 million for fiscal 2014 with an effective income tax rate of 32.1%.   Included in fiscal 2014 income tax expense are items related to the acquisition of Delta Egg, which resulted in a $3.3 million decrease to deferred income tax expense related to the outside basis of our equity investment in Delta Egg, with a corresponding non-recurring, non-cash $1.5 million reduction to income taxes expense on the non-taxable remeasurement gain associated with the acquisition.

Other items causing our effective rate to differ from the federal statutory income tax rate of 35% are state income taxes and certain items included in income or loss for financial reporting purposes that are not included in taxable income or loss for income tax purposes, including tax exempt interest income, the domestic manufacturers deduction, and net income or loss attributable to noncontrolling interest.

NET INCOME ATTRIBUTABLE TO NONCONTROLLING INTEREST

Net income attributable to noncontrolling interest in AEP and TEP for fiscal 2015 was $1.0 million as compared to $600,000 for fiscal 2014.

NET INCOME ATTRIBUTABLE TO CAL-MAINE FOODS, INC.

As a result of the above, net income for fiscal 2015 was $161.3 million, or $3.35 per basic share and $3.33 per diluted share, compared to $109.2 million, or $2.27 per basic share and $2.26 per diluted share for fiscal 2014. 

CAPITAL RESOURCES AND LIQUIDITY

Our working capital at May 28, 2016 was $542.8 million, compared to $407.4 million at May 30, 2015. The calculation of working capital is defined as current assets less current liabilities.  Our current ratio was 7.50 at May 28, 2016 compared to 5.01 at May 30, 2015. The current ratio is calculated by dividing current assets by current liabilities.  Our need for working capital generally is highest in the last and first fiscal quarters ending in May and August, respectively, when egg prices are normally at seasonal lows.  We have $3.7 million in outstanding standby letters of credit, which are collateralized with cash.  Our long-term debt at May 28, 2016, including current maturities, amounted to $25.6 million, compared to $50.9 million at May 30, 2015.  See Note 9 in the Notes to Consolidated Financial  Statements for information regarding our long-term debt instruments.

Net cash provided by operating activities was $381.8 million and $195.3 million for the fiscal years 2016 and 2015, respectively.  Improved gross profit margins contributed greatly to our positive cash flow from operations in fiscal 2016 compared to fiscal 2015.  As discussed above, our gross profit margins increased in fiscal 2016 primarily as a result of an increase in egg prices and a decrease in feed costs compared to fiscal 2015. 

31

For fiscal 2016, approximately $292.5 million was provided from the sale of short-term investments, $403.2 million was used to purchase short-term investments and net payments of $5.4 million were received from notes receivable and investments in affiliates.   We used $34.0 million for our investment in the Red River Valley Egg Farm LLC joint venture.  For additional information see Note 3 to Notes to Consolidated Financial Statements.  Approximately $76.1 million was used to purchaseproperty, plant and equipment.  Refer to the table of material construction projects presented below for additional information on purchases of property, plant and equipment.  Approximately $120.9 million was used to pay dividends on common stock and $25.3 million was used for principal payments on long-term debt.  The net result of these activities was anincrease in cash of $20.4million from May 30, 2015.

For the fiscal year ended May 30, 2015, $195.3 million in net cash was provided by operating activities. This compares to $123.9 million of net cash provided by operating activities for the fiscal year ended May 31, 2014.  Improved gross profit margins contributed greatly to our positive cash flow from operations in fiscal 2015 compared to fiscal 2014, as well as fiscal 2014 payment of a $28.0 million legal settlement.  As discussed above, our gross profit margins increased in fiscal 2015 primarily as a result of an increase in egg prices and dozens sold and a decrease in feed costs compared to fiscal 2014. 

For fiscal 2015, approximately $146.8 million was provided from the sale of short-term investments, $202.5 million was used to purchase short-term investments and net payments of $2.0 million were received from notes receivable and investments in affiliates.   We used $8.2 million for our investment in Southwest Specialty Egg LLC joint venture.  For additional information see Note 3 to Notes to Consolidated Financial Statements.  Approximately $82.3 million was used to purchase property, plant and equipment.  Refer to the table of material construction projects presented below for additional information on purchases of property, plant and equipment.  Approximately $48.9 million was used to pay dividends on common stock and $10.2 million was used for principal payments on long-term debt.  The net result of these activities was a decrease in cash of $5.9 million from May 31, 2014.

Certain property, plant, and equipment is pledged as collateral on our notes payable and senior secured notes.  Unless otherwise approved by our lenders, we are required by provisions of our loan agreements to (1) maintain minimum levels of working capital (current ratio of not less than 1.25 to 1) and net worth (minimum of $90.0 million tangible net worth, plus 45% of cumulative net income since the fiscal year ended May 28, 2005); (2) limit dividends paid in any given quarter to not exceed an amount equal to one third of the previous quarter’s consolidated net income (allowed if no events of default); (3) maintain minimum total funded debt to total capitalization (debt to total tangible capitalization ratio not to exceed 55%); and (4) maintain various cash-flow coverage ratios (1.25 to 1), among other restrictions. At May 28, 2016, we were in compliance with the financial covenant requirements of all loan agreements. Under certain of the loan agreements, the lenders have the option to require the prepayment of any outstanding borrowings in the event we undergo a change in control, as defined in the applicable loan agreement. Our debt agreements require Fred R. Adams, Jr., our Founder and Chairman Emeritus, or his family, to maintain ownership of Company shares representing not less than 50% of the outstanding voting power of the Company. 

32

We have been making and expect to continue to make significant investments in new and remodeled facilities to meet the increasing demand for cage-free, organic and other specialty eggs, including through our previously discussed Red River joint venture. We expect to fund approximately $7.5 million for our remaining 50% share of the construction and startup costs for the Red River joint venture during fiscal 2017.  The complex is expected to be completely stocked in early calendar 2017.  Additionally, the following table represents material construction projects approved as of July 14, 2016(in thousands):

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

For information on changes in accounting principles and new accounting principles, see “Impact of Recently Issued Accounting Standards” in Note 1 to the Consolidated Financial Statements.

33

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with U.S. generally accepted accounting standards requires management to make estimates and assumptions that affect the reported amounts of 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 these estimates.

Management suggests our Summary of Significant Accounting Policies, as described in Note 1 of the notes to consolidated financial statements, be read in conjunction with this Management’s Discussion and Analysis of Financial Condition and Results of Operations. We believe the critical accounting policies that most impact our consolidated financial statements are described below.

INVESTMENTS IN SECURITIES AVAILABLE-FOR-SALE

Our investment securities are accounted for in accordance with ASC 320, “Investments-Debt and Equity Securities” (“ASC 320”).  The Company considers all investment securities for which there is a determinable fair market value and no restrictions on the Company's ability to sell within the next 12 months as available-for-sale, and carries them at fair value, with unrealized gains and losses reported as a separate component of stockholders' equity. Realized gains and losses are included in other income. The cost basis for realized gains and losses on available-for-sale securities is determined on the specific identification method.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

In the normal course of business, we extend credit to our customers on a short-term basis.  Although credit risk associated with our customers is considered minimal, we routinely review our accounts receivable balances and make provisions for probable doubtful accounts. In circumstances where management is aware of a specific customer’s inability to meet its financial obligations to us (e.g. bankruptcy filings), a specific reserve is recorded to reduce the receivable to the amount expected to be collected.  For all other customers, we recognize reserves for bad debt based on the length of time the receivables are past due, generally 100% for amounts more than 60 days past due.

INVENTORIES

Inventories of eggs, feed, supplies and livestock are valued principally at the lower of cost (first-in, first-out method) or market.  If market prices for eggs and feed grains move substantially lower, we record adjustments to write-down the carrying values of eggs and feed inventories to fair market value. The cost associated with flock inventories, consisting principally of chick purchases, feed, labor, contractor payments and overhead costs, are accumulated during the growing period of approximately 22 weeks.  Capitalized flock costs are then amortized over the flock’s productive life, generally one to two years.  Flock mortality is charged to cost of sales as incurred.  High mortality from disease or extreme temperatures would result in abnormal write-downs to flock inventories.  Management continually monitors each flock and attempts to take appropriate actions to minimize the risk of mortality loss.

LONG-LIVED ASSETS

Depreciable long-lived assets are primarily comprised of buildings and improvements and machinery and equipment.  Depreciation is provided by the straight-line method over the estimated useful lives, which are 15 to 25 years for buildings and improvements and 3 to 12 years for machinery and equipment.  An increase or decrease in the estimated useful lives would result in changes to depreciation expense.  When property and equipment are retired, sold, or otherwise disposed of, the asset’s carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in operations. We continually reevaluate the carrying value of our long-lived assets, for events or changes in circumstances which indicate the carrying value may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition.  If the sum of the expected future cash flows (undiscounted and without interest charges) are less than the carrying amount of the asset, an impairment loss is recognized to reduce the carrying value of the long-lived asset to the estimated fair value of the asset.

INTANGIBLE ASSETS

Included in other intangible assets are separable intangible assets acquired in business acquisitions, which include franchise fees, non-compete agreements and customer relationship intangibles, and are amortized over their estimated useful lives of 3 to 25

34

years.   The gross cost and accumulated amortization of intangible assets are removed when the recorded amounts are fully amortized and the asset is no longer in use.  Included in other long-lived assets are loan acquisition costs, which are amortized over the life of the related loan.

INVESTMENT IN AFFILIATES

We have invested in other companies engaged in the production, processing and distribution of shell eggs and egg products.  Our ownership percentages in these companies range from less than 20% to 50%.  These investments are recorded using the cost or equity method, and are not consolidated in our financial statements.  Changes in the ownership percentages of these investments might alter the accounting methods currently used. Our investment in these companies amounted to $51.0 million at May 28, 2016. The combined total assets and total liabilities of these companies were approximately $444.2 million and $77.0million, respectively, at May 28, 2016.

GOODWILL

At May 28, 2016, goodwill represented2.6% of total assets and 3.2% of stockholders’ equity.  Goodwill relates to the following:

Fiscal Year	Description	Amount
1999	Acquisition of Hudson Brothers, Inc.	$3,147
2006	Acquisition of Hillandale Farms, LLC	869
2007	Acquisition of Green Forest Foods, LLC	179
2008	Revised Hillandale incremental purchase price	9,257
2009	Revised Hillandale incremental purchase price	2,527
2009	Acquisition of Zephyr Egg, LLC	1,876
2009	Acquisition of Tampa Farms, LLC	4,600
2010	Revised Hillandale incremental purchase price	(338)
2013	Acquisition of Maxim Production Co., Inc.	2,300
2014	Purchase of joint venture partner’s 50% in Delta Egg	4,779
	Total Goodwill	$29,196

Goodwill is evaluated for impairment annually by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary.After assessing the totality of events or circumstances, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform additional quantitative tests to determine the magnitude of any impairment.

REVENUE RECOGNITION AND DELIVERY COSTS

The Company recognizes revenue only when all of the following criteria have been met:

· Persuasive evidence of an arrangement exists;

· Delivery has occurred;

· The fee for the arrangement is determinable; and

· Collectability is reasonably assured.

The Company believes the above criteria are met upon delivery and acceptance of the product by our customers. Costs to deliver product to customers are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income and totaled $49.6 million, $47.0 million, and $43.0 million in fiscal years 2016, 2015, and 2014, respectively.  Sales revenue reported in the accompanying consolidated statements of income is reduced to reflect estimated returns and allowances.  The Company records an estimated sales allowance for returns and discounts at the time of sale using historical trends based on actual sales returns and sales.

35

SALES INCENTIVES PROVIDED TO CUSTOMERS

The Company periodically provides incentive offers to its customers to encourage purchases. Such offers include current discount offers (e.g., percentage discounts off current purchases), inducement offers (e.g., offers for future discounts subject to a minimum current purchase), and other similar offers. Current discount offers, when accepted by customers, are treated as a reduction to the sales price of the related transaction, while inducement offers, when accepted by customers, are treated as a reduction to sales price based on estimated future redemption rates. Redemption rates are estimated using the Company’s historical experience for similar inducement offers. Current discount and inducement offers are presented as a net amount in ‘‘Net sales.’’

STOCK BASED COMPENSATION

We account for share-based compensation in accordance with ASC 718, “Compensation-Stock Compensation” (“ASC 718”).  ASC 718 requires all share-based payments to employees, including grants of employee stock options, restricted stock and performance-based shares to be recognized in the income statement based on their fair values. ASC 718 requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow.  See Note 11: Stock Compensation Plans in the Notes to the Consolidated Financial Statements for more information.

INCOME TAXES

We determine our effective tax rate by estimating our permanent differences resulting from differing treatment of items for tax and accounting purposes.  We are periodically audited by taxing authorities.  Any audit adjustments affecting permanent differences could have an impact on our effective tax rate.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

COMMODITY PRICE RISK

Our primary exposure to market risk arises from changes in the prices of eggs, corn and soybean meal, which are commodities subject to significant price fluctuations due to market conditions that are largely beyond our control.  For example, feed costs, which during fiscal 2016 averaged approximately 60% of our total farm egg production cost, decreased 15.7% per dozen produced year-over-year.    We are focused on growing our specialty shell egg business because the selling prices of specialty shell eggs are generally not as volatile as non-specialty shell egg prices.  The following table outlines the impact of price changes for corn and soybean meal on feed cost per dozen:

Feed ingredient			Approximate change in  feed ingredient cost	Approximate impact on feed costs per dozen	Approximate dollar impact on farm production cost for the 2016 fiscal year
Corn	$	0.25	change in the average market price per bushel	$                0.01	$                      8,193,070
Soybean Meal	$	25.00	change in the average market price per ton	$                0.01	$                      8,193,070

We generally do not enter into long-term contracts to purchase corn and soybean meal or hedge against increases in the price of corn and soybean meal.

INTEREST RATE RISK

The fair value of our debt is sensitive to changes in the general level of U.S. interest rates.  We maintain all of our debt as fixed rate in nature to mitigate the impact of fluctuations in interest rates.  Under our current policies, we do not use interest rate derivative instruments to manage our exposure to interest rate changes.  A 1% adverse move (decrease) in interest rates would adversely affect the net fair value of our debt by $300,000 at May 28, 2016. 

We are not a party to any other material market risk sensitive instruments requiring disclosure.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Cal-Maine Foods, Inc. and Subsidiaries

Jackson, Mississippi

We have audited the accompanying consolidated balance sheets of Cal-Maine Foods, Inc. and Subsidiaries as of May 28, 2016 and May 30, 2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of the years in the three-year period ended May 28, 2016.  Our audits also included the consolidated financial statement schedule listed in the Index at Item 15(a).  These consolidated financial statements are the responsibility of the entity’s management.  Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Cal-Maine Foods, Inc. and Subsidiaries as of May 28, 2016 and May 30, 2015, and the results of their operations and their cash flows for each of the years in the three-year period ended May 28, 2016, in conformity with accounting principles generally accepted in the United States of America.  In addition, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Cal-Maine Foods, Inc. and Subsidiaries internal control over financial reporting as of May 28, 2016, based on criteria established in 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated July 15, 2016, expressed an unqualified opinion.

Cal-Maine Foods, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

May 28, 2016

1. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Cal-Maine Foods, Inc. and its subsidiaries (“we,” “us,” “our,” or the “Company”). All significant intercompany transactions and accounts have been eliminated in consolidation.

Business

The Company is principally engaged in the production, processing and distribution of shell eggs. The Company’s operations are significantly affected by the market price fluctuation of its principal product, shell eggs, and the costs of its principal feed ingredients, corn, soybean meal, and other grains.

The Company sells shell eggs to a diverse group of customers, including national and local grocery store chains, club stores, foodservice distributors, and egg product consumers.  The Company’s sales are primarily in the southeastern, southwestern, mid-westernand mid-Atlantic regions of the United States. Credit is extended based upon an evaluation of each customer’s financial condition and credit history and generally collateral is not required. Credit losses have consistently been within management’s expectations. Two customers, Wal-Mart and Sam’s Club, on a combined basis, accounted for 28.9%,  25.7% and 28.2% of the Company’s net sales in fiscal years 2016,  2015, and 2014, respectively.

Fiscal Year

The Company’s fiscal year-end is on the Saturday nearest May 31, which was May 28, 2016,  May 30, 2015,  and May 31, 2014 for the most recent three fiscal years. All three years fiscal years were 52 week years.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We maintain bank accounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000.  AtMay 28, 2016and routinely throughout these years, the Company maintained cash balances with certain financial institutions in excess of federally insured amounts. The Company has not experienced any losses in such accounts.  The Company manages this risk through maintaining cash deposits and other highly liquid investments in high quality financial institutions. 

We primarily utilize a cash management system with a series of separate accounts consisting of lockbox accounts for receiving cash, concentration accounts where funds are moved to, and several zero-balance disbursement accounts for funding payroll and accounts payable. Checks issued, but not presented to the banks for payment, may result in negative book cash balances, which are included in accounts payable. AtMay 28, 2016, andMay 30, 2015, checks outstanding in excess of related book cash balances totaled zeroand$1.8million, respectively.

43

Investment Securities

Our investment securities are accounted for in accordance with ASC 320, “Investments-Debt and Equity Securities” (“ASC 320”).  The Company considers all of its investment securities for which there is a determinable fair market value and there are no restrictions on the Company's ability to sell within the next 12 months as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses reported as a separate component of stockholders' equity. We had unrealized gains, net of tax, of $363,000 and $372,000at May 28, 2016 and May 30, 2015, respectively, which are included in the line item “Accumulated other comprehensive income (loss), net of tax” on our Consolidated Balance Sheet. Realized gains and losses are included in other income. The cost basis for realized gains and losses on available-for-sale securities is determined on the specific identification method.

At May 28, 2016 and May 30, 2015, we had $360.5million and $250.0million, respectively, of current investment securities available-for-sale consisting of commercial paper, time deposits, U.S. government obligations, government agency bonds, taxable municipal bonds, tax-exempt municipal bonds, zero coupon municipal bonds and corporate bonds with maturities of three months or longer when purchased. We classified these securities as current, because the amounts invested are available for current operations.  At May 28, 2016 and May 30, 2015 we had $1.9 million and $1.7 million, respectively, of investments in mutual funds which are considered long term and are a part of “Other Investments” in the Consolidated Balance Sheet.

Investment in Affiliates

The equity method of accounting is used when the Company has a 20% to 50% interest in other entities or when the Company exercises significant influence over the entity. Under the equity method, original investments are recorded at cost and adjusted by the Company’s share of undistributed earnings or losses of these entities. Nonmarketable investments in which the Company has less than a 20% interest and in which it does not have the ability to exercise significant influence over the investee are initially recorded at cost, and periodically reviewed for impairment.

Trade Receivables and Allowance for Doubtful Accounts

Trade receivables are comprised primarily of amounts owed to the Company from customers, which amounted to $62.0million at May 28, 2016 and $99.0million at May 30, 2015.  They are presented net of an allowance for doubtful accounts of $727,000 at May 28, 2016 and $513,000 at May 30, 2015. The Company extends credit to customers based upon an evaluation of each customer’s financial condition and credit history. Although credit risks associated with our customers are considered minimal, we routinely review our accounts receivable balances and make provisions for probable doubtful accounts. In circumstances where management is aware of a specific customer’s inability to meet its financial obligations to us (e.g., bankruptcy filings), a reserve is recorded to reduce the receivable to the amount expected to be collected. For all other customers, we recognize reserves for bad debt based on the length of time the receivables are past due, generally 100% for amounts more than 60 days past due. Collateral is generally not required. Credit losses have consistently been within management’s expectations. At both May 28, 2016 and May 30, 2015two customers accounted for approximately 29%and 24%of the Company’s trade accounts receivable, respectively.

Inventories

Inventories of eggs, feed, supplies and livestock are valued principally at the lower of cost (first-in, first-out method) or market.

The cost associated with flocks, consisting principally of chick purchases, feed, labor, contractor payments and overhead costs, are accumulated during a growing period of approximately 22 weeks. Flock costs are amortized to cost of sales over the productive lives of the flocks, generally one to two years. Flock mortality is charged to cost of sales as incurred.

The Company does not disclose the gross cost and accumulated amortization with respect to its flock inventories since this information is not utilized by management in the operation of the Company.

44

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is provided by the straight-line method over the estimated useful lives, which are 15 to 25 years for buildings and improvements and 3 to 12 years for machinery and equipment. Repairs and maintenance are expensed as incurred. Expenditures that increase the value or productive capacity of assets are capitalized. When property, plant, and equipment are retired, sold, or otherwise disposed of, the asset’s carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in operations. The Company capitalizes interest cost incurred on funds used to construct property, plant, and equipment as part of the asset to which it relates, and is amortized over the asset’s estimated useful life.

Impairment of Long-Lived Assets

The Company reviews the carrying value of long-lived assets, other than goodwill, for impairment whenever events and circumstances indicate the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where expected future cash flows (undiscounted and without interest charges) are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. The factors considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the property is used, and the effects of obsolescence, demand, competition, and other economic factors.

Intangible Assets

Included in other intangible assets are separable intangible assets acquired in business acquisitions, which include franchise fees, non-compete agreements and customer relationship intangibles, and are amortized over their estimated useful lives of 3 to 25 years.   The gross cost and accumulated amortization of intangible assets are removed when the recorded amounts have been fully amortized and the asset is no longer in use or the contract has expired.  Included in other long-lived assets are loan acquisition costs, which are amortized over the life of the related loan.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill is evaluated for impairment annually by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary.  After assessing the totality of events or circumstances, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform additional quantitative tests to determine the magnitude of any impairment.

Accrued Self Insurance

We use a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for health and welfare, workers’ compensation, auto liability and general liability risks. Liabilities associated with our risks retained are estimated, in part, by considering claims experience, demographic factors, severity factors and other actuarial assumptions. 

Dividends

Cal-Maine 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 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 65th 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, 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.  Dividends payable werezeroand$15.4million at May 28, 2016 and May 30, 2015, respectively.These amounts represent accrued unpaid dividends applicable to the Company’s fourth quarter net income for each fiscal year.

45

Treasury Stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.  The grant of restricted stock through the Company’s share-based compensation plans is funded through the issuance of treasury stock.  Gains and losses on the subsequent reissuance of shares in accordance with the Company’s share-based compensation plans are credited or charged to paid-in capital in excess of par value using the average-cost method.

Revenue Recognition and Delivery Costs

The Company recognizes revenue only when all of the following criteria have been met:

· Persuasive evidence of an arrangement exists;

· Delivery has occurred;

· The fee for the arrangement is determinable; and

· Collectability is reasonably assured.

The Company believes the above criteria are met upon delivery and acceptance of the product by our customers. Costs to deliver product to customers are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income and totaled $49.6million, $47.0 million, and $43.0 million in fiscal years 2016,  2015, and 2014, respectively.  Sales revenue reported in the accompanying consolidated statements of income is reduced to reflect estimated returns and allowances.  The Company records an estimated sales allowance for returns and discounts at the time of sale using historical trends based on actual sales returns and sales.

Sales Incentives provided to Customers

The Company periodically provides incentive offers to its customers to encourage purchases. Such offers include current discount offers (e.g., percentage discounts off current purchases), inducement offers (e.g., offers for future discounts subject to a minimum current purchase), and other similar offers. Current discount offers, when accepted by customers, are treated as a reduction to the sales price of the related transaction, while inducement offers, when accepted by customers, are treated as a reduction to sales price based on estimated future redemption rates. Redemption rates are estimated using the Company’s historical experience for similar inducement offers. Current discount and inducement offers are presented as a net amount in ‘‘Net sales.’’

Advertising Costs

The Company expensed advertising costs as incurred of $10.3million, $9.3 million, and $8.5million in fiscal 2016,  2015, and 2014, respectively.  

Income Taxes

Income taxes are provided using the liability method. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.The Company’s policy with respect to evaluating uncertain tax positions is based upon whether management believes it is more likely than not the uncertain tax positions will be sustained upon review by the taxing authorities.  The tax positions must meet the more-likely-than-not recognition threshold with consideration given to the amounts and probabilities of the outcomes that could be realized upon settlement using the facts, circumstances and information at the reporting date.  The Company will reflect only the portion of the tax benefit that will be sustained upon resolution of the position and applicable interest on the portion of the tax benefit not recognized. The Company shall initially and subsequently measure the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.    Based upon management’s assessment, there are no uncertain tax positions expected to have a material impact on the Company’s consolidated financial statements.

46

Stock Based Compensation

We account for share-based compensation in accordance with ASC 718, “Compensation-Stock Compensation” (“ASC 718”).  ASC 718 requires all share-based payments to employees, including grants of employee stock options, restricted stock and performance-based shares to be recognized in the income statement based on their fair values. ASC 718 requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow.  See Note 11: Stock Compensation Plans for more information.

Net Income per Common Share

Basic net income per share is based on the weighted average common and Class A shares outstanding. Diluted net income per share includes any dilutive effects of stock options outstanding and unvested restricted shares.

Basic net income per share was calculated by dividing net income by the weighted-average number of common and Class A shares outstanding during the period.  Diluted net income 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 stock options and unvested restricted shares.  The computations of basic net income per share and diluted net income per share are as follows (in thousands):

	May 28, 2016	May 30, 2015	May 31, 2014
Net income attributable to Cal-Maine Foods, Inc.	$          316,041	$        161,254	$        109,207
Basic weighted-average common shares (including Class A)	48,195	48,136	48,095
Effect of dilutive securities:
Common stock options and restricted stock	170	301	202
Dilutive potential common shares	48,365	48,437	48,297
Net income per common share:
Basic	$                6.56	$              3.35	$              2.27
Diluted	$                6.53	$              3.33	$              2.26

Contingencies

Certain conditions may exist as of the date the financial statements are issued that may result in a loss to the Company but which will only be resolved when one or more future events occur or fail to occur. The Company’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or unasserted claims that may result in such proceedings, the Company’s legal counsel evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates it is probable that a material loss has been incurred and the amount of the liability can be estimated, the estimated liability would be 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. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the nature of the guarantee would be disclosed. 

The Company expenses the costs of litigation as they are incurred.

47

Impact of Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer in an amount that reflects the consideration that is expected to be received for those goods or services.  In August 2015, FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company does notexpectASU 2014-09to have a material impacton the consolidated financial statement presentation.

In November 2015, the FASB issued ASU 2015-17, Income Taxes – Balance Sheet Classification of Deferred Taxes.  The purpose of the standard is to simplify the presentation of deferred taxes on a classified balance sheet.  Under current GAAP, deferred income tax assets and liabilities are separated into current and noncurrent amounts in the balance sheet.  The amendments in ASU 2015-17 require that all deferred tax assets and liabilities be classified as noncurrent in the balance sheet.  ASU 2015-17 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods.  Early application is permitted.  The Company adopted ASU 2015-17 during the fourth quarter of fiscal 2016 and retrospectively applied it to all reported periods.  Adoption of ASU 2015-17 impacted our previously reported current ratio for fiscal 2015 by increasing it from 3.86 as reported in the prior year to 5.01 as reported in this report.

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 guidance will require balance sheet recognition for assets and liabilities associated with rights and obligations created by leases with terms greater than twelve months.  ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods.  Early adoption is permitted.  The Company is currently evaluating the impact of ASU 2016-02 on its financial statements and presentation.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Compensation Accounting. ASU 2016-09 requires that excess tax benefits are recorded on the income statement as opposed to additional paid-in-capital, and treated as an operating activity on the statement of cash flows. ASU 2016-09 also allows companies to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.  The Company does notexpectASU 2016-09to have a material impacton the consolidated financial statement presentation.

2.  Acquisition

Effective March 1, 2014, the Company purchased our joint venture partner’s 50% interest in Delta Egg Farm, LLC (“Delta Egg”) for $17.0 million.  The Company previously owned 50% of Delta Egg through a joint venture with Moark, LLC.  In conjunction with the acquisition, the Company recognized a non-recurring, non-cash gain of $4.0 million for the excess in purchase price over the carrying value of the 50% investment in the unconsolidated joint venture.  This gain was recorded in “Other Income” in the Company’s Consolidated Statements of Income for fiscal 2014.  The gain is non-taxable, and therefore resulted in a $1.5 million reduction to the Company’s income tax expense for fiscal 2014.  Additionally, the Company recorded a $3.3 million decrease to deferred income tax liabilities related to the outside basis of our equity investment in Delta Egg.  Delta Egg’s assets include a feed mill and a production complex with capacity for approximately 1.2 million laying hens near Delta, Utah, as well as an organic complex with capacity for approximately 400,000 laying hens near Chase, Kansas. 

The results of the Company’s operation of these assets are included in the Company’s consolidated financial statements since the respective dates of acquisition. Included in the Company’s consolidated financial statements for fiscal 2014 are revenues and net income from Delta Egg of $4.7 million and $1.3 million, respectively.  Prior to the acquisition date the Company’s 50% share of net income was recorded “Equity in income of affiliates”.

3.  Investment in Affiliates

On April 9, 2015, the Company entered into the Red River Valley Egg Farm, LLC (“Red River”) joint venture with Rose Acre Farms, Inc.  The joint venture operates a state of the art shell egg production complex near Bogata, Red River County, Texas.  The plans for the completedcomplex provide capacity for approximately 1.8 million cage-free laying hens.  As of May 28, 2016, the Company has contributed $34.0 million to fund its 50% share of the construction costs and expects to make future contributions of approximately $7.5 million.

On July 25, 2014, the Company entered into the Southwest Specialty Eggs, LLC (“SWS”) joint venture with Hickman’s Egg Ranch.  The SWS joint venture subsequently acquired the Egg-Land’s Best franchise for Arizona,  southern California and Clark County (including Las Vegas), Nevada.  The Company owns 50% of the SWS joint venture.

The Company owns 50% of each of Specialty Eggs LLC and Dallas Reinsurance, Co., LTD. as of May 28, 2016.  During fiscal 2014 the Company purchased our joint venture partner’s 50% interest in Delta Egg Farm (Refer to Note 2 – Acquisitions).  Investment in affiliates, recorded using the equity method of accounting, are included in “Other Investments” in the accompanying Consolidated Balance Sheets and totaled $47.5million and $13.1million at May 28, 2016 and at May 30, 2015, respectively. 

Equity in income of $5.0million, $2.7million, and $3.5million from these entities has been included in the Consolidated Statements of Income for fiscal 2016,  2015, and 2014, respectively.

The Company is a member of Eggland’s Best, Inc. (“EB”), which is a cooperative.  At May 28, 2016 and May 30, 2015, “Other Investments” as shown on the Company’s Consolidated Balance Sheet includes the cost of the Company’s investment in EB plus any qualified written allocations.  The Company cannot exert significant influence over EB’s operating and financial activities; therefore, the Company accounts for this investment using the cost method.   The carrying value of this investment at May 28, 2016 and May 30, 2015 was $3.5 million and $3.1 million, respectively.

The Company has a KSOP plan that covers substantially all employees (“the Plan”).  The Company makes cash contributions to the Plan at a rate of 3% of participants' eligible compensation, plus an additional amount determined at the discretion of the Board of Directors.  Contributions can be made in cash or the Company's common stock, and vest immediately.   The Company's cash contributions to the Plan were $2.9 million, $2.8 million, and $3.0 million in fiscal years 2016,  2015 and 2014, respectively. The Company did not make direct contributions of the Company’s common stock in fiscal years 2016,  2015, or 2014. Dividends on the Company’s common stock are paid to the Plan in cash.  The Plan acquires the Company’s common stock, which is listed on the NASDAQ, by using the dividends and the Company’s cash contribution to purchase shares in the public markets.  The Plan sold common stock on the NASDAQ to pay benefits to Plan participants.  Participants may make contributions to the Plan up to the maximum allowed by the Internal Revenue Service regulations.  The Company does not match participant contributions.

The plan is accounted for in accordance with ASC 715, “Compensation – Retirement Benefits”, whereby an employer recognizes the funded status of a defined benefit postretirement plan as an asset or liability, and recognizes changes in the funded status in the year the change occurs through comprehensive income.  Additionally, this expense is recognized on an accrual basis over the employees’ approximate period of employment. The liability associated with the plan was $1.8million and $1.5million as of May 28, 2016 and May 30, 2015, respectively.  The remaining disclosures associated with ASC 715 are immaterial to the company’s financial statements.

On July 28, 2005, the Company’s Board of Directors approved the Cal-Maine Foods, Inc. Stock Appreciation Rights Plan (the "Rights Plan"). The Rights Plan covers 2,000,000 shares of Common Stock of the Company. Stock Appreciation Rights ("SARs") may be granted to any employee or non-employee member of the Board of Directors. Upon exercise of a SAR, the holder will receive cash equal to the difference between the fair market value of a single share of Common Stock at the time of exercise and the strike price which is equal to the fair market value of a single share of Common Stock on the date of the grant. The SARs have a ten-year term and vest over five years. On August 17, 2005, the Company issued 1,185,000 SARs under the Rights Plan with a strike price of $2.97 and, on August 26, 2005, the Company issued 90,000 SARs with a strike price of $3.36. On August 24, 2006, the Company issued 30,000 SARs with a strike price of $3.47. The Rights Plan was ratified by the Company’s shareholders at the annual meeting of shareholders on October 13, 2005.  The last remaining SARs were exercised during fiscal 2016 which effectively terminated this plan.

On October 5, 2012, shareholders approved the Cal-Maine Foods, Inc. 2012 Omnibus Long-Term Incentive Plan (“2012 Plan”). The purpose of the 2012 Plan is to assist us and our subsidiaries in attracting and retaining selected individuals who, serving as our employees, outside directors and consultants, are expected to contribute to our success and to achieve long-term objectives which will benefit our shareholders through the additional incentives inherent in the awards under the 2012 Plan. The maximum number of shares of common stock that are available for awards under the 2012 Plan is 1,000,000 shares issuable from the Company’s treasury stock.  Awards may be granted under the 2012 Plan to any employee, any non-employee member of the Company’s Board of Directors, and any consultant who is a natural person and provides services to us or one of our subsidiaries (except for incentive stock options which may be granted only to our employees).

In January 2016, the Company granted 78,560  restricted shares from treasury.  The restricted shares vest three years from the grant date, or upon death or disability, change in control, or retirement (subject to certain requirements).The restricted shares contain no other service or performance conditions.  Restricted stock is awarded in the name of the recipient and except for the right of disposal, constitutes issued and outstanding shares of the Company’s common stock for all corporate purposes during the period of restriction including the right to receive dividends.  Compensation expense is a fixed amount based on the grant date closing price and is amortized over the vesting period. 

Our unrecognized compensation expense as a result of non-vested shares was $5.6 million as of both May 28, 2016 and May 30, 2015.  The unrecognized compensation expense will be amortized to stock compensation expense over a period of 2.1 years.

Federal and state income taxes of $167.2 million, $75.5 million,  and $41.6 million were paid in fiscal years 2016,  2015, and2014,respectively. Federal and state income taxes of $320,000,  zero, and zero were refunded in fiscal years 2016,  2015,  and 2014, respectively.

We had no significant unrecognized tax benefits at May 28, 2016 or at May 30, 2015. Accordingly, we do not have any accrued interest or penalties related to uncertain tax positions. However, if interest or penalties were to be incurred related to uncertain tax positions, such amounts would be recognized in income tax expense.

We are under a limited scope audit by the IRS for the fiscal years 2013 through 2015.   We are subject to income tax in many jurisdictions within the U.S., and certain jurisdictions are under audit by state and local tax authorities.  The resolutions of these audits are not expected to be material to our consolidated financial statements.  Tax periods for all years after fiscal year 2012 remain open to examination by the federal and state taxing jurisdictions to which we are subject.

13. Contingencies

Financial Instruments

The Company maintains standby letters of credit (“LOC”) with a bank totaling $3.7 million at May 28, 2016.  These LOCs are collateralized with cash. The cash that collateralizes the LOCs is included in the line item “Other assets” in the consolidated balance sheets.  The outstanding LOCs are for the benefit of certain insurance companies. None of the LOCs are recorded as a liability on the Consolidated Balance Sheets.

Litigation

The Company is a defendant in certain legal actions, and intends to vigorously defend its position in these actions. The Company assesses the likelihood of material adverse judgments or outcomes to the extent losses are reasonably estimable.  If the assessment of a contingency indicates it is probable that 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.

Egg Antitrust Litigation

Since September 25, 2008, the Company has been named as one of several defendants in numerous antitrust cases involving the United States shell egg industry.  In some of these cases, the named plaintiffs allege that they purchased eggs or egg products directly from a defendant and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.  In other cases, the named plaintiffs allege that they purchased shell eggs and egg products directly from one or more of the defendants but sue only for their own alleged damages and not on behalf of a putative class.  In the remaining cases, the named plaintiffs are individuals or companies who allege that they purchased shell eggs indirectly from one or more of the defendants – that is, they purchased from retailers that had previously purchased from defendants or other parties – and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.

The Judicial Panel on Multidistrict Litigation consolidated all of the putative class actions (as well as certain other cases in which the Company was not a named defendant) for pretrial proceedings in the United States District Court for the Eastern District of Pennsylvania. The Pennsylvania court has organized the putative class actions around two groups (direct purchasers and indirect purchasers) and has named interim lead counsel for the named plaintiffs in each group. 

The Direct Purchaser Putative Class Action. The direct purchaser putative class 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.  As previously reported, in November 2014, the Court approved the Company’s settlement with the direct purchaser plaintiff class and entered final judgment dismissing with prejudice the class members’ claims against the Company.  

The Indirect Purchaser Putative Class Action.  The indirect purchaser putative class 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.  On April 20-21, 2015, the Court held an evidentiary hearing on the indirect purchaser plaintiffs’ motion for class certification. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of the entire case or, in the alternative, dismissal of portions of the case.  On July 2, 2015, the indirect purchaser plaintiffs filed motions for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal and state antitrust laws. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions. On September 18, 2015, the Court denied the indirect purchaser plaintiffs’ motion for class certification of 21 separate classes seeking damages under the laws of 21 states, holding that the plaintiffs were not able to prove that their purported method for ascertaining class membership was reliable or administratively feasible, that common questions would predominate, or that their proposed class approach would be manageable in a single trial.  In addition to barring any right to pursue a class monetary remedy under state law, the Court also denied indirect purchaser plaintiffs’ request for certification of an injunctive-relief class under federal law.  However, the court allowed the indirect purchaser plaintiffs to renew their motion for class certification seeking a federal injunction.  The plaintiffs filed their renewed motion to certify an injunctive-relief class on October 23, 2015.  The Company joined the other defendants in opposing that motion on November 20.  The plaintiffs filed their reply memorandum on December 11, 2015. The plaintiffs requested oral argument on their renewed motion for injunctive class

58

certification.  The plaintiffs also filed a petition with the United States Court of Appeals for the Third Circuit, asking the court to hear an immediate appeal of the trial court’s denial of the motion to certify 21 state-law damages classes.  On December 3, 2015, the Third Circuit entered an order staying its consideration of the plaintiffs’ request for an immediate appeal of the damages-class ruling pending the trial court’s resolution of the plaintiffs’ renewed motion to certify an injunctive-relief class. 

The Non-Class Cases. Six of the cases in which plaintiffs do not seek to certify a class have been consolidated with the putative class actions 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 court granted with prejudice the defendants’ renewed motion to dismiss the non-class plaintiffs’ claims for damages arising before September 24, 2004. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of all of the claims in all of these cases or, in the alternative, dismissal of portions of these cases.  On July 2, 2015, the non-class plaintiffs filed a motion for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal antitrust law. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions.

 Allegations in Each Case. In all of the cases described above, the plaintiffs allege that the Company and certain other large domestic egg producers conspired to reduce the domestic supply of eggs in a concerted effort to raise the price of eggs to artificially high levels.  In each case, plaintiffs allege that all defendants agreed to reduce the domestic supply of eggs by: (a) agreeing to limit production; (b) manipulating egg exports; and (c) implementing industry-wide animal welfare guidelines that reduced the number of hens and eggs. 

The named plaintiffs in the remaining indirect purchaser putative class action seek treble damages under the statutes and common-law of various states and injunctive relief under the Sherman Act on behalf of themselves and all other putative class members in the United States. Although plaintiffs allege a class period starting in October, 2006 and running “through the present,” the Court denied the plaintiffs’ motion to certify classes seeking damages under the laws of 21 states and denied without prejudice the plaintiffs’ motion to certify an injunctive-relief class, although the plaintiffs have filed a renewed motion to certify an injunctive-relief class, as discussed above. 

Five of the original six non-class cases remain pending against the Company.  The principal plaintiffs in these cases are: The Kroger Co.; Publix Super Markets, Inc.; SUPERVALU, Inc.; Safeway, Inc.; Albertsons LLC; H.E. Butt Grocery Co.; The Great Atlantic & Pacific Tea Company, Inc.; Walgreen Co.; Hy-Vee, Inc.; Kraft Food Global, Inc., General Mills, Inc., Nestle USA, Inc., and The Kellogg Company.  In four of these remaining non-class cases, the plaintiffs seek treble damages and injunctive relief under the Sherman Act.  In the fifth remaining non-class case, the plaintiff seeks treble damages and injunctive relief under the Sherman Act and the Ohio antitrust act (known as the Valentine Act). 

The Pennsylvania court has entered a series of orders related to case management, discovery, class certification, summary judgment, and scheduling.  The Pennsylvania court has not set a trial date for any of the Company’s remaining consolidated cases (non-class and indirect purchaser cases).

The Company intends to continue to defend the remaining cases 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 these cases.  Accordingly, adjustments, if any, which might result from the resolution of these remaining legal matters, have not been reflected in the financial statements.

State of Oklahoma Watershed Pollution Litigation

On June 18, 2005, the State of Oklahoma filed suit, in the United States District Court for the Northern District of Oklahoma, against Cal-Maine Foods, Inc. and Tyson Foods, Inc. and affiliates, Cobb-Vantress, Inc., Cargill, Inc. and its affiliate, George’s, Inc. and its affiliate, Peterson Farms, Inc. and Simmons Foods, Inc. The State of Oklahoma claims that through the disposal of chicken litter the defendants have polluted the Illinois River Watershed. This watershed provides water to eastern Oklahoma. The complaint seeks injunctive relief and monetary damages, but the claim for monetary damages has been dismissed by the court. Cal-Maine Foods, Inc. discontinued operations in the watershed. Accordingly, we do not anticipate that Cal-Maine Foods, Inc. will be materially affected by the request for injunctive relief unless the court orders substantial affirmative remediation. Since the litigation began, Cal-Maine Foods, Inc. purchased 100% of the membership interests of Benton County Foods, LLC, which is an ongoing commercial shell egg operation within the Illinois River Watershed. Benton County Foods, LLC is not a defendant in the litigation.

The trial in the case began in September 2009 and concluded in February 2010. The case was tried to the court without a jury and the court has not yet issued its ruling. Management believes the risk of material loss related to this matter to be remote.

Florida Civil Investigative Demand

On November 4, 2008, the Company received an antitrust civil investigative demand from the Attorney General of the State of Florida. The demand seeks production of documents and responses to interrogatories relating to the production and sale of eggs and egg products. The Company is cooperating with this investigation and has, on three occasions, entered into an agreement with the State of Florida tolling the statute of limitations applicable to any supposed claims the State is investigating. No allegations of wrongdoing have been made against the Company in this matter.

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.

At this time, it is not possible for us to predict the ultimate outcome of the matters set forth above.

14.   Description of Rights and Privileges of Capital Stock—Capital Structure Consists of Common Stock and Class A Common Stock

The Company has two classes of capital stock: Common Stock and Class A Common Stock. Holders of shares of the Company’s capital stock vote as a single class on all matters submitted to a vote of the stockholders, with each share of Common Stock entitled to one vote and each share of Class A Common Stock entitled to ten votes. The Common Stock and Class A Common Stock have equal liquidation rights and the same dividend rights.  In the case of any stock dividend, holders of Common Stock are entitled to receive the same percentage dividend (payable only in shares of Common Stock) as the holders of Class A Common Stock receive (payable only in shares of Class A Common Stock). Upon liquidation, dissolution, or winding-up of the Company, the holders of Common Stock are entitled to share ratably with the holders of Class A Common Stock in all assets available for distribution after payment in full of creditors. The Class A Common Stock may only be issued to Fred R. Adams, Jr., the Company’s Founder and Chairman Emeritus, and members of his immediate family, as defined. In the event any share of Class A Common Stock, by operation of law or otherwise is, or shall be deemed to be owned by any person other than Mr. Adams or a member of his immediate family, the voting power of such stock will be reduced from ten votes per share to one vote per share. Also, shares of Class A Common Stock shall be automatically converted into Common Stock on a share per share basis in the event the beneficial or record ownership of any such share of Class A Common Stock is transferred to any person other than Mr. Adams or a member of his immediate family. Each share of Class A Common Stock is convertible, at the option of its holder, into one share of Common Stock at any time. The holders of Common Stock and Class A Common Stock are not entitled to preemptive or subscription rights. In any merger, consolidation or business combination, the consideration to be received per share by holders of Common Stock must be identical to that received by holders of Class A Common Stock, except that if any such transaction in which shares of Capital Stock are distributed, such shares may differ as to voting rights to the extent that voting rights now differ among the classes of capital stock. No class of capital stock may be combined or subdivided unless the other classes of capital stock are combined or subdivided in the same proportion. No dividend may be declared and paid on Class A Common Stock unless the dividend is payable only to the holders of Class A Common Stock and a dividend is declared and paid to Common Stock concurrently.

60

On July 25, 2014, the Board of Directors approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to authorize an additional 60,000,000 shares of common stock and an additional 2,400,000 shares of Class A common stock.  The primary purpose of the amendment was to provide a sufficient number of authorized shares in order to effect a 2-for-1 stock split of the Company’s common stock and Class A common stock.  The amendment was approved by the Company’s stockholders at the Company’s annual meeting on October 3, 2014 and the Board of Directors approved the 2-for-1 stock split on the same day.  The new shares were distributed on October 31, 2014 to shareholders of record at the close of business on October 17, 2014. 

Unless otherwise noted, all prior period share and per share information contained in this report was adjusted to reflect the effect of the stock split.

15.  Fair Value Measures

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 supported by little or no market activity and are significant to the fair value of the assets or liabilities.

The disclosure of fair value of certain financial assets and liabilities recorded at cost are as follows:

Cash and cash equivalents, accounts receivable, and accounts payable: 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. Estimated fair values are management’s estimates, which is a level 3 input; 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. The fair value of the Company’s debt is sensitive to changes in the general level of U.S. interest rates.  The Company maintains all of its debt as fixed rate in nature to mitigate the impact of fluctuations in interest rates.  Under its current policies, the Company does not use interest rate derivative instruments to manage its exposure to interest rate changes.  A one percent (1%) adverse move (i.e. decrease) in interest rates would adversely affect the net fair value of the Company’s debt by $300,000 at May 28, 2016.  The fair value and carrying value of the Company’s long-term debt were as follows (in thousands):

	May 28, 2016				May 30, 2015
	Carrying Value		Fair Value		Carrying Value		Fair Value
5.40 – 6.40% Notes payable	$	25,570	$	25,824	$	44,549	$	45,158

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 our financial assets and liabilities that are required to be measured at fair value on a recurring basis as of May 28, 2016 and May 30, 2015 (in thousands):

Our investment securities – available-for-sale classified as level 2 consist of certificates of deposit, time deposits, U.S. government and agency obligations, taxable and tax exempt municipal bonds, zero coupon municipal bonds, asset-backed securities, foreign government obligations, and corporate bonds with maturities of three months or longer when purchased. 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.  Liabilities for contingent consideration (earn-outs) take into account commodity prices based on published

62

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 business acquisitions.  Given the unobservable nature of these inputs, they are deemed to be Level 3fair value measurements.  During fiscal 2015 we recognized a $239,000 loss resulting from the increase in fair value of the contingent consideration.In fiscal 2014 we recognized a $4.4 million loss.  Both the losses were recognized in earnings as an increase of selling, general, and administrative expenses.  Changes in the fair value of contingent consideration obligations for fiscal 2016 were as follows (in thousands):

Proceeds from the sales of available-for-sale securities were $292.5 million, $146.8 million, and $108.1 million during fiscal 2016, 2015, and 2014, respectively. Gross realized gains on those sales during fiscal 2016,  2015, and 2014 were $131,000, $82,000, and $8,000, respectively. Gross realized losses on those sales during fiscal 2016,  2015,  and 2014 were $110,000, $7,000, and $2,000, 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 (losses) net of tax on available-for-sale securities classified as current in the amount of $22,000, $(149,000), and $149,000 for the years ended May 28, 2016,  May 30, 2015,  and May 31, 2014, respectively, have been included in accumulated other comprehensive income (loss).  Unrealized holding gains (losses) net of tax on long term available-for-sale securities in the amount of $(31,000),  $59,000 and $90,000 for the years ended May 28, 2016,May 30, 2015, and May 31, 2014 have been included in other comprehensive income (loss).

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.  Contractual maturities of investment securities at May 28, 2016, are as follows (in thousands):

ITEM 9A.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms.  Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on an evaluation of our disclosure controls and procedures conducted by our Chief Executive Officer and Chief Financial Officer, together with other financial officers, such officers concluded that our disclosure controls and procedures were effective as of May 28, 2016 at the reasonable assurance level.

Internal Control Over Financial Reporting

(a)Management’s Report on Internal Control Over Financial Reporting

The following sets forth, in accordance with Section 404(a) of the Sarbanes-Oxley Act of 2002 and Item 308 of the Securities and Exchange Commission’s Regulation S-K, the report of management on our internal control over financial reporting.

1.Our management is responsible for establishing and maintaining adequate internal control over financial reporting. “Internal control over financial reporting” is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, together with other financial officers, and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

· Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

· Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

· Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

2.Our management, in accordance with Rule 13a-15(c) under the Exchange Act and with the participation of our Chief Executive Officer and Chief Financial Officer, together with other financial officers, evaluated the effectiveness of our internal control over financial reporting as of May 28, 2016.  The framework on which management’s evaluation of our internal control over financial reporting is based is the “Internal Control – Integrated Framework”published in 2013 by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission.

3.Management has determined that our internal control over financial reporting as of May 28, 2016 is effective. It is noted that internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives, but rather reasonable assurance of achieving such objectives.

4.The attestation report of FROST, PLLC on our internal control over financial reporting, which includes that firm’s opinion on the effectiveness of our internal control over financial reporting, is set forth below.

(b)AttestationReport of the Registrant’s Public Accounting Firm

Report of Independent Registered Public Accounting Firm

on Internal Control Over Financial Reporting

Board of Directors and Stockholders

Cal-Maine Foods, Inc. and Subsidiaries

Jackson, Mississippi

We have audited Cal-Maine Foods, Inc. and Subsidiaries’ internal control over financial reporting as of May 28, 2016, based on criteria established in 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).  Cal-Maine Foods, Inc. and Subsidiaries’ management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting in Item 9A.  Our responsibility is to express an opinion on the entity’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audit also included performing such other procedures as we considered necessary in the circumstances.  We believe our audit provides a reasonable basis for our opinion.

An entity’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  An entity’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and directors of the entity; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the entity’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Cal-Maine Foods, Inc. and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of May 28, 2016, based on criteria established in 2013 Internal Control-Integrated Framework issued by the COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets and the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows of Cal-Maine Foods, Inc. and Subsidiaries, and our report dated July 15, 2016, expressed an unqualified opinion.

(c)Changes in Internal Control Over Financial Reporting

In connection with its evaluation of the effectiveness, as of May 28, 2016, of our internal control over financial reporting, management determined that there was no change in our internal control over financial reporting that occurred during the fourth quarter ended May 28, 2016, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

1. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Cal-Maine Foods, Inc. and its subsidiaries (“we,” “us,” “our,” or the “Company”).  All significant intercompany transactions and accounts have been eliminated in consolidation.

Business

The Company is principally engaged in the production, processing and distribution of shell eggs. The Company’s operations are significantly affected by the market price fluctuation of its principal product, shell eggs, and the costs of its principal feed ingredients, corn, soybean meal, and other grains.

The Company sells shell eggs to a diverse group of customers, including national and local grocery store chains, club stores, foodservice distributors, and egg product consumers.  The Company’s sales are primarily in the southeastern, southwestern, mid-western and mid-Atlantic regions of the United States. Credit is extended based upon an evaluation of each customer’s financial condition and credit history and generally collateral is not required. Credit losses have consistently been within management’s expectations. Two customers, Wal-Mart and Sam’s Club, on a combined basis, accounted for 28.9%,  25.7% and 28.2% of the Company’s net sales in fiscal years 2016,  2015, and 2014, respectively.

Fiscal Year

The Company’s fiscal year-end is on the Saturday nearest May 31, which was May 28, 2016,  May 30, 2015, and May 31, 2014 for the most recent three fiscal years. All three years fiscal years were 52 week years.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We maintain bank accounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000.  At May 28, 2016 and routinely throughout these years, the Company maintained cash balances with certain financial institutions in excess of federally insured amounts. The Company has not experienced any losses in such accounts.  The Company manages this risk through maintaining cash deposits and other highly liquid investments in high quality financial institutions. 

We primarily utilize a cash management system with a series of separate accounts consisting of lockbox accounts for receiving cash, concentration accounts where funds are moved to, and several zero-balance disbursement accounts for funding payroll and accounts payable. Checks issued, but not presented to the banks for payment, may result in negative book cash balances, which are included in accounts payable. AtMay 28, 2016, andMay 30, 2015, checks outstanding in excess of related book cash balances totaled zeroand$1.8 million, respectively.

Investment Securities

Our investment securities are accounted for in accordance with ASC 320, “Investments-Debt and Equity Securities” (“ASC 320”).  The Company considers all of its investment securities for which there is a determinable fair market value and there are no restrictions on the Company's ability to sell within the next 12 months as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses reported as a separate component of stockholders' equity. We had unrealized gains, net of tax, of $363,000 and $372,000 at May 28, 2016 and May 30, 2015, respectively, which are included in the line item “Accumulated other comprehensive income (loss), net of tax” on our Consolidated Balance Sheet. Realized gains and losses are included in other income. The cost basis for realized gains and losses on available-for-sale securities is determined on the specific identification method.

At May 28, 2016 and May 30, 2015, we had $360.5 million and $250.0 million, respectively, of current investment securities available-for-sale consisting of commercial paper, time deposits, U.S. government obligations, government agency bonds, taxable municipal bonds, tax-exempt municipal bonds, zero coupon municipal bonds and corporate bonds with maturities of three months or longer when purchased. We classified these securities as current, because the amounts invested are available for current operations.  At May 28, 2016 and May 30, 2015 we had $1.9 million and $1.7 million, respectively, of investments in mutual funds which are considered long term and are a part of “Other Investments” in the Consolidated Balance Sheet.

Investment in Affiliates

The equity method of accounting is used when the Company has a 20% to 50% interest in other entities or when the Company exercises significant influence over the entity. Under the equity method, original investments are recorded at cost and adjusted by the Company’s share of undistributed earnings or losses of these entities. Nonmarketable investments in which the Company has less than a 20% interest and in which it does not have the ability to exercise significant influence over the investee are initially recorded at cost, and periodically reviewed for impairment.

Trade Receivables and Allowance for Doubtful Accounts

Trade receivables are comprised primarily of amounts owed to the Company from customers, which amounted to $62.0 million at May 28, 2016 and $99.0 million at May 30, 2015. They are presented net of an allowance for doubtful accounts of $727,000 at May 28, 2016 and $513,000 at May 30, 2015. The Company extends credit to customers based upon an evaluation of each customer’s financial condition and credit history. Although credit risks associated with our customers are considered minimal, we routinely review our accounts receivable balances and make provisions for probable doubtful accounts. In circumstances where management is aware of a specific customer’s inability to meet its financial obligations to us (e.g., bankruptcy filings), a reserve is recorded to reduce the receivable to the amount expected to be collected. For all other customers, we recognize reserves for bad debt based on the length of time the receivables are past due, generally 100% for amounts more than 60 days past due. Collateral is generally not required. Credit losses have consistently been within management’s expectations. At both May 28, 2016 and May 30, 2015two customers accounted for approximately 29% and 24% of the Company’s trade accounts receivable, respectively.

Inventories

Inventories of eggs, feed, supplies and livestock are valued principally at the lower of cost (first-in, first-out method) or market.

The cost associated with flocks, consisting principally of chick purchases, feed, labor, contractor payments and overhead costs, are accumulated during a growing period of approximately 22 weeks. Flock costs are amortized to cost of sales over the productive lives of the flocks, generally one to two years. Flock mortality is charged to cost of sales as incurred.

The Company does not disclose the gross cost and accumulated amortization with respect to its flock inventories since this information is not utilized by management in the operation of the Company.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is provided by the straight-line method over the estimated useful lives, which are 15 to 25 years for buildings and improvements and 3 to 12 years for machinery and equipment. Repairs and maintenance are expensed as incurred. Expenditures that increase the value or productive capacity of assets are capitalized. When property, plant, and equipment are retired, sold, or otherwise disposed of, the asset’s carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in operations. The Company capitalizes interest cost incurred on funds used to construct property, plant, and equipment as part of the asset to which it relates, and is amortized over the asset’s estimated useful life.

Impairment of Long-Lived Assets

The Company reviews the carrying value of long-lived assets, other than goodwill, for impairment whenever events and circumstances indicate the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where expected future cash flows (undiscounted and without interest charges) are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. The factors considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the property is used, and the effects of obsolescence, demand, competition, and other economic factors.

Intangible Assets

Included in other intangible assets are separable intangible assets acquired in business acquisitions, which include franchise fees, non-compete agreements and customer relationship intangibles, and are amortized over their estimated useful lives of 3 to 25 years.   The gross cost and accumulated amortization of intangible assets are removed when the recorded amounts have been fully amortized and the asset is no longer in use or the contract has expired.  Included in other long-lived assets are loan acquisition costs, which are amortized over the life of the related loan.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill is evaluated for impairment annually by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary.  After assessing the totality of events or circumstances, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform additional quantitative tests to determine the magnitude of any impairment.

Accrued Self Insurance

We use a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for health and welfare, workers’ compensation, auto liability and general liability risks. Liabilities associated with our risks retained are estimated, in part, by considering claims experience, demographic factors, severity factors and other actuarial assumptions. 

Dividends

Cal-Maine 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 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 65th 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, 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.  Dividends payable were zero and $15.4 million at May 28, 2016 and May 30, 2015, respectively. These amounts represent accrued unpaid dividends applicable to the Company’s fourth quarter net income for each fiscal year.

Treasury Stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.  The grant of restricted stock through the Company’s share-based compensation plans is funded through the issuance of treasury stock.  Gains and losses on the subsequent reissuance of shares in accordance with the Company’s share-based compensation plans are credited or charged to paid-in capital in excess of par value using the average-cost method.

Revenue Recognition and Delivery Costs

The Company recognizes revenue only when all of the following criteria have been met:

· Persuasive evidence of an arrangement exists;

· Delivery has occurred;

· The fee for the arrangement is determinable; and

· Collectability is reasonably assured.

The Company believes the above criteria are met upon delivery and acceptance of the product by our customers. Costs to deliver product to customers are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income and totaled $49.6 million, $47.0 million, and $43.0 million in fiscal years 2016,  2015, and 2014, respectively.  Sales revenue reported in the accompanying consolidated statements of income is reduced to reflect estimated returns and allowances.  The Company records an estimated sales allowance for returns and discounts at the time of sale using historical trends based on actual sales returns and sales.

Sales Incentives provided to Customers

The Company periodically provides incentive offers to its customers to encourage purchases. Such offers include current discount offers (e.g., percentage discounts off current purchases), inducement offers (e.g., offers for future discounts subject to a minimum current purchase), and other similar offers. Current discount offers, when accepted by customers, are treated as a reduction to the sales price of the related transaction, while inducement offers, when accepted by customers, are treated as a reduction to sales price based on estimated future redemption rates. Redemption rates are estimated using the Company’s historical experience for similar inducement offers. Current discount and inducement offers are presented as a net amount in ‘‘Net sales.’’

Advertising Costs

The Company expensed advertising costs as incurred of $10.3 million, $9.3 million, and $8.5 million in fiscal 2016,  2015, and 2014, respectively.  

Income Taxes

Income taxes are provided using the liability method. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company’s policy with respect to evaluating uncertain tax positions is based upon whether management believes it is more likely than not the uncertain tax positions will be sustained upon review by the taxing authorities.  The tax positions must meet the more-likely-than-not recognition threshold with consideration given to the amounts and probabilities of the outcomes that could be realized upon settlement using the facts, circumstances and information at the reporting date.  The Company will reflect only the portion of the tax benefit that will be sustained upon resolution of the position and applicable interest on the portion of the tax benefit not recognized. The Company shall initially and subsequently measure the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.    Based upon management’s assessment, there are no uncertain tax positions expected to have a material impact on the Company’s consolidated financial statements.

Stock Based Compensation

We account for share-based compensation in accordance with ASC 718, “Compensation-Stock Compensation” (“ASC 718”).  ASC 718 requires all share-based payments to employees, including grants of employee stock options, restricted stock and performance-based shares to be recognized in the income statement based on their fair values. ASC 718 requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow.  See Note 11: Stock Compensation Plans for more information.

Net Income per Common Share

Basic net income per share is based on the weighted average common and Class A shares outstanding. Diluted net income per share includes any dilutive effects of stock options outstanding and unvested restricted shares.

Basic net income per share was calculated by dividing net income by the weighted-average number of common and Class A shares outstanding during the period.  Diluted net income 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 stock options and unvested restricted shares.  The computations of basic net income per share and diluted net income per share are as follows (in thousands):

	May 28, 2016	May 30, 2015	May 31, 2014
Net income attributable to Cal-Maine Foods, Inc.	$          316,041	$        161,254	$        109,207
Basic weighted-average common shares (including Class A)	48,195	48,136	48,095
Effect of dilutive securities:
Common stock options and restricted stock	170	301	202
Dilutive potential common shares	48,365	48,437	48,297
Net income per common share:
Basic	$                6.56	$              3.35	$              2.27
Diluted	$                6.53	$              3.33	$              2.26

Contingencies

Certain conditions may exist as of the date the financial statements are issued that may result in a loss to the Company but which will only be resolved when one or more future events occur or fail to occur. The Company’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or unasserted claims that may result in such proceedings, the Company’s legal counsel evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates it is probable that a material loss has been incurred and the amount of the liability can be estimated, the estimated liability would be 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. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the nature of the guarantee would be disclosed. 

The Company expenses the costs of litigation as they are incurred.

Impact of Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer in an amount that reflects the consideration that is expected to be received for those goods or services.  In August 2015, FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company does notexpectASU 2014-09to have a material impacton the consolidated financial statement presentation.

In November 2015, the FASB issued ASU 2015-17, Income Taxes – Balance Sheet Classification of Deferred Taxes.  The purpose of the standard is to simplify the presentation of deferred taxes on a classified balance sheet.  Under current GAAP, deferred income tax assets and liabilities are separated into current and noncurrent amounts in the balance sheet.  The amendments in ASU 2015-17 require that all deferred tax assets and liabilities be classified as noncurrent in the balance sheet.  ASU 2015-17 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods.  Early application is permitted.  The Company adopted ASU 2015-17 during the fourth quarter of fiscal 2016 and retrospectively applied it to all reported periods.  Adoption of ASU 2015-17 impacted our previously reported current ratio for fiscal 2015 by increasing it from 3.86 as reported in the prior year to 5.01 as reported in this report.

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 guidance will require balance sheet recognition for assets and liabilities associated with rights and obligations created by leases with terms greater than twelve months.  ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods.  Early adoption is permitted.  The Company is currently evaluating the impact of ASU 2016-02 on its financial statements and presentation.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Compensation Accounting. ASU 2016-09 requires that excess tax benefits are recorded on the income statement as opposed to additional paid-in-capital, and treated as an operating activity on the statement of cash flows. ASU 2016-09 also allows companies to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.  The Company does notexpectASU 2016-09to have a material impacton the consolidated financial statement presentation.

Acquisition [Abstract]

Acquisition

2.  Acquisition

Effective March 1, 2014, the Company purchased our joint venture partner’s 50% interest in Delta Egg Farm, LLC (“Delta Egg”) for $17.0 million.  The Company previously owned 50% of Delta Egg through a joint venture with Moark, LLC.  In conjunction with the acquisition, the Company recognized a non-recurring, non-cash gain of $4.0 million for the excess in purchase price over the carrying value of the 50% investment in the unconsolidated joint venture.  This gain was recorded in “Other Income” in the Company’s Consolidated Statements of Income for fiscal 2014.  The gain is non-taxable, and therefore resulted in a $1.5 million reduction to the Company’s income tax expense for fiscal 2014.  Additionally, the Company recorded a $3.3 million decrease to deferred income tax liabilities related to the outside basis of our equity investment in Delta Egg.  Delta Egg’s assets include a feed mill and a production complex with capacity for approximately 1.2 million laying hens near Delta, Utah, as well as an organic complex with capacity for approximately 400,000 laying hens near Chase, Kansas. 

The results of the Company’s operation of these assets are included in the Company’s consolidated financial statements since the respective dates of acquisition. Included in the Company’s consolidated financial statements for fiscal 2014 are revenues and net income from Delta Egg of $4.7 million and $1.3 million, respectively.  Prior to the acquisition date the Company’s 50% share of net income was recorded “Equity in income of affiliates”.

3.  Investment in Affiliates

On April 9, 2015, the Company entered into the Red River Valley Egg Farm, LLC (“Red River”) joint venture with Rose Acre Farms, Inc.  The joint venture operates a state of the art shell egg production complex near Bogata, Red River County, Texas.  The plans for the completed complex provide capacity for approximately 1.8 million cage-free laying hens.  As of May 28, 2016, the Company has contributed $34.0 million to fund its 50% share of the construction costs and expects to make future contributions of approximately $7.5 million. 

On July 25, 2014, the Company entered into the Southwest Specialty Eggs, LLC (“SWS”) joint venture with Hickman’s Egg Ranch.  The SWS joint venture subsequently acquired the Egg-Land’s Best franchise for Arizona, southern California and Clark County (including Las Vegas), Nevada.  The Company owns 50% of the SWS joint venture.

The Company owns 50% of each of Specialty Eggs LLC and Dallas Reinsurance, Co., LTD. as of May 28, 2016.  During fiscal 2014 the Company purchased our joint venture partner’s 50% interest in Delta Egg Farm (Refer to Note 2 – Acquisitions).  Investment in affiliates, recorded using the equity method of accounting, are included in “Other Investments” in the accompanying Consolidated Balance Sheets and totaled $47.5 million and $13.1 million at May 28, 2016 and at May 30, 2015, respectively. 

Equity in income of $5.0 million, $2.7 million, and $3.5 million from these entities has been included in the Consolidated Statements of Income for fiscal 2016,  2015, and 2014, respectively.

The Company is a member of Eggland’s Best, Inc. (“EB”), which is a cooperative.  At May 28, 2016 and May 30, 2015, “Other Investments” as shown on the Company’s Consolidated Balance Sheet includes the cost of the Company’s investment in EB plus any qualified written allocations.  The Company cannot exert significant influence over EB’s operating and financial activities; therefore, the Company accounts for this investment using the cost method.   The carrying value of this investment at May 28, 2016 and May 30, 2015 was $3.5 million and $3.1 million, respectively.

The Company regularly transacts business with its affiliates. The following relates to the Company’s transactions with these unconsolidated affiliates (in thousands):

Employee Benefit Plans

10.  Employee Benefit Plans

The Company maintains a medical plan that is qualified under Section 401(a) of the Internal Revenue Code and is not subject to tax under present income tax laws.  The plan is funded by contributions from the Company and its employees.  Under its plan, the Company self-insures its portion of medical claims for substantially all full-time employees.  The Company uses stop-loss insurance to limit its portion of medical claims to $225,000 per occurrence.  The Company's expenses including accruals for incurred but not reported claims were approximately $11.8 million, $9.6 million, and $9.8 million in fiscal years 2016,  2015 and 2014, respectively.  The liability recorded for incurred but not reported claims was $770,000 as of May 28, 2016 and  700,000 as of May 30, 2015.

The Company has a KSOP plan that covers substantially all employees (“the Plan”).  The Company makes cash contributions to the Plan at a rate of 3% of participants' eligible compensation, plus an additional amount determined at the discretion of the Board of Directors.  Contributions can be made in cash or the Company's common stock, and vest immediately.   The Company's cash contributions to the Plan were $2.9 million, $2.8 million, and $3.0 million in fiscal years 2016,  2015 and 2014, respectively. The Company did not make direct contributions of the Company’s common stock in fiscal years 2016,  2015, or 2014. Dividends on the Company’s common stock are paid to the Plan in cash.  The Plan acquires the Company’s common stock, which is listed on the NASDAQ, by using the dividends and the Company’s cash contribution to purchase shares in the public markets.  The Plan sold common stock on the NASDAQ to pay benefits to Plan participants.  Participants may make contributions to the Plan up to the maximum allowed by the Internal Revenue Service regulations.  The Company does not match participant contributions.

The Company has deferred compensation agreements with certain officers for payments to be made over specified periods beginning when the officers reach age 65 or over as specified in the agreements.  Amounts accrued for the agreements are based upon deferred compensation earned over the estimated remaining service period of each officer.  Payments made under the plan were $102,000,  $97,000, and $50,000in fiscal years 2016,  2015, and 2014, respectively.  The liability recorded related to these agreements was $1.6 million at May 28, 2016 and May 30, 2015. 

In December 2006, the Company adopted an additional deferred compensation plan to provide deferred compensation to named officers of the Company.  The awards issued under this plan were $284,000, $241,000, and $202,000 in fiscal 2016,  2015 and 2014, respectively.  Payments made under the plan were $128,000 and 116,000 in fiscal 2016 and 2015, respectively.  The liability recorded related to these agreements was $1.9 million and $1.7 million at May 28, 2016 and May 30, 2015, respectively.

Deferred compensation expense for both plans totaled $347,000, $470,000 and $425,000 in fiscal 2016,  2015 and 2014, respectively.

Postretirement Medical Plan

The Company maintains an unfunded postretirement medical plan to provide limited health benefits to certain qualified retired employees and officers.  Retired non-officers and spouses are eligible for coverage until attainment of Medicare eligibility, at which time coverage ceases.  Retired officers and spouses are eligible for lifetime benefits under the plan.  Officers and their spouses, who retired prior to May 1, 2012, must participate in Medicare Plans A and B.  Officers, and their spouses, who retire on or after May 1, 2012 must participate in Medicare Plans A, B, and D. 

The plan is accounted for in accordance with ASC 715, “Compensation – Retirement Benefits”, whereby an employer recognizes the funded status of a defined benefit postretirement plan as an asset or liability, and recognizes changes in the funded status in the year the change occurs through comprehensive income.  Additionally, this expense is recognized on an accrual basis over the employees’ approximate period of employment. The liability associated with the plan was $1.8million and $1.5million as of May 28, 2016 and May 30, 2015, respectively.  The remaining disclosures associated with ASC 715 are immaterial to the company’s financial statements.

Stock Compensation Plans

11.  Stock Compensation Plans

On July 28, 2005, the Company’s Board of Directors approved the Cal-Maine Foods, Inc. Stock Appreciation Rights Plan (the "Rights Plan"). The Rights Plan covers 2,000,000 shares of Common Stock of the Company. Stock Appreciation Rights ("SARs") may be granted to any employee or non-employee member of the Board of Directors. Upon exercise of a SAR, the holder will receive cash equal to the difference between the fair market value of a single share of Common Stock at the time of exercise and the strike price which is equal to the fair market value of a single share of Common Stock on the date of the grant. The SARs have a ten-year term and vest over five years. On August 17, 2005, the Company issued 1,185,000 SARs under the Rights Plan with a strike price of $2.97 and, on August 26, 2005, the Company issued 90,000 SARs with a strike price of $3.36. On August 24, 2006, the Company issued 30,000 SARs with a strike price of $3.47. The Rights Plan was ratified by the Company’s shareholders at the annual meeting of shareholders on October 13, 2005.  The last remaining SARs were exercised during fiscal 2016 which effectively terminated this plan.

On October 5, 2012, shareholders approved the Cal-Maine Foods, Inc. 2012 Omnibus Long-Term Incentive Plan (“2012 Plan”). The purpose of the 2012 Plan is to assist us and our subsidiaries in attracting and retaining selected individuals who, serving as our employees, outside directors and consultants, are expected to contribute to our success and to achieve long-term objectives which will benefit our shareholders through the additional incentives inherent in the awards under the 2012 Plan. The maximum number of shares of common stock that are available for awards under the 2012 Plan is 1,000,000 shares issuable from the Company’s treasury stock.  Awards may be granted under the 2012 Plan to any employee, any non-employee member of the Company’s Board of Directors, and any consultant who is a natural person and provides services to us or one of our subsidiaries (except for incentive stock options which may be granted only to our employees).

In January 2016, the Company granted 78,560  restricted shares from treasury.  The restricted shares vest three years from the grant date, or upon death or disability, change in control, or retirement (subject to certain requirements).The restricted shares contain no other service or performance conditions.  Restricted stock is awarded in the name of the recipient and except for the right of disposal, constitutes issued and outstanding shares of the Company’s common stock for all corporate purposes during the period of restriction including the right to receive dividends.  Compensation expense is a fixed amount based on the grant date closing price and is amortized over the vesting period. 

Our unrecognized compensation expense as a result of non-vested shares was $5.6 million as of both May 28, 2016 and May 30, 2015.  The unrecognized compensation expense will be amortized to stock compensation expense over a period of 2.1 years.

The Company recognized stock compensation expense of $1.7 million for equity awards and $1.3million for liability awards in fiscal 2016.  In fiscal 2015, the Company recognized stock compensation expense of $2.3 million for equity awards and $749,000 for liability awards.  In fiscal 2014 the Company recognized stock compensation expense of $1.3 million for equity awards and $521,000 for liability awards.

We determined the fair value of our obligation related to unexercised liability awards as of May 28, 2016 and May 30, 2015 was zero and $1.4 million, respectively.  Total payments for liability awards exercised totaled $1.4 million,  $407,000, and $373,000 for fiscal 2016, 2015 and 2014, respectively.

The fair value of liability awards was estimated as of May 30, 2015, and May31, 2014, using a Black-Scholes option pricing model using the following weighted-average assumptions:

	May 30, 2015	May 31, 2014

Federal and state income taxes of $167.2 million, $75.5 million, and $41.6 million were paid in fiscal years 2016, 2015, and 2014, respectively. Federal and state income taxes of $320,000,  zero, and zero were refunded in fiscal years 2016, 2015,  and 2014, respectively.

We had no significant unrecognized tax benefits at May 28, 2016 or at May 30, 2015. Accordingly, we do not have any accrued interest or penalties related to uncertain tax positions. However, if interest or penalties were to be incurred related to uncertain tax positions, such amounts would be recognized in income tax expense.

We are under a limited scope audit by the IRS for the fiscal years 2013 through 2015.   We are subject to income tax in many jurisdictions within the U.S., and certain jurisdictions are under audit by state and local tax authorities.  The resolutions of these audits are not expected to be material to our consolidated financial statements.  Tax periods for all years after fiscal year 2012 remain open to examination by the federal and state taxing jurisdictions to which we are subject.

Contingencies [Abstract]

Contingencies

13. Contingencies

Financial Instruments

The Company maintains standby letters of credit (“LOC”) with a bank totaling $3.7 million at May 28, 2016.  These LOCs are collateralized with cash. The cash that collateralizes the LOCs is included in the line item “Other assets” in the consolidated balance sheets.  The outstanding LOCs are for the benefit of certain insurance companies. None of the LOCs are recorded as a liability on the Consolidated Balance Sheets.

Litigation

The Company is a defendant in certain legal actions, and intends to vigorously defend its position in these actions. The Company assesses the likelihood of material adverse judgments or outcomes to the extent losses are reasonably estimable.  If the assessment of a contingency indicates it is probable that 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.

Egg Antitrust Litigation

Since September 25, 2008, the Company has been named as one of several defendants in numerous antitrust cases involving the United States shell egg industry.  In some of these cases, the named plaintiffs allege that they purchased eggs or egg products directly from a defendant and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.  In other cases, the named plaintiffs allege that they purchased shell eggs and egg products directly from one or more of the defendants but sue only for their own alleged damages and not on behalf of a putative class.  In the remaining cases, the named plaintiffs are individuals or companies who allege that they purchased shell eggs indirectly from one or more of the defendants – that is, they purchased from retailers that had previously purchased from defendants or other parties – and have sued on behalf of themselves and a putative class of others who claim to be similarly situated.

The Judicial Panel on Multidistrict Litigation consolidated all of the putative class actions (as well as certain other cases in which the Company was not a named defendant) for pretrial proceedings in the United States District Court for the Eastern District of Pennsylvania. The Pennsylvania court has organized the putative class actions around two groups (direct purchasers and indirect purchasers) and has named interim lead counsel for the named plaintiffs in each group. 

The Direct Purchaser Putative Class Action. The direct purchaser putative class 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.  As previously reported, in November 2014, the Court approved the Company’s settlement with the direct purchaser plaintiff class and entered final judgment dismissing with prejudice the class members’ claims against the Company.  

The Indirect Purchaser Putative Class Action.  The indirect purchaser putative class 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.  On April 20-21, 2015, the Court held an evidentiary hearing on the indirect purchaser plaintiffs’ motion for class certification. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of the entire case or, in the alternative, dismissal of portions of the case.  On July 2, 2015, the indirect purchaser plaintiffs filed motions for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal and state antitrust laws. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions. On September 18, 2015, the Court denied the indirect purchaser plaintiffs’ motion for class certification of 21 separate classes seeking damages under the laws of 21 states, holding that the plaintiffs were not able to prove that their purported method for ascertaining class membership was reliable or administratively feasible, that common questions would predominate, or that their proposed class approach would be manageable in a single trial.  In addition to barring any right to pursue a class monetary remedy under state law, the Court also denied indirect purchaser plaintiffs’ request for certification of an injunctive-relief class under federal law.  However, the court allowed the indirect purchaser plaintiffs to renew their motion for class certification seeking a federal injunction.  The plaintiffs filed their renewed motion to certify an injunctive-relief class on October 23, 2015.  The Company joined the other defendants in opposing that motion on November 20.  The plaintiffs filed their reply memorandum on December 11, 2015. The plaintiffs requested oral argument on their renewed motion for injunctive class certification.  The plaintiffs also filed a petition with the United States Court of Appeals for the Third Circuit, asking the court to hear an immediate appeal of the trial court’s denial of the motion to certify 21 state-law damages classes.  On December 3, 2015, the Third Circuit entered an order staying its consideration of the plaintiffs’ request for an immediate appeal of the damages-class ruling pending the trial court’s resolution of the plaintiffs’ renewed motion to certify an injunctive-relief class. 

The Non-Class Cases.  Six of the cases in which plaintiffs do not seek to certify a class have been consolidated with the putative class actions 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 court granted with prejudice the defendants’ renewed motion to dismiss the non-class plaintiffs’ claims for damages arising before September 24, 2004. On July 2, 2015, the Company filed and joined several motions for summary judgment that sought either dismissal of all of the claims in all of these cases or, in the alternative, dismissal of portions of these cases.  On July 2, 2015, the non-class plaintiffs filed a motion for summary judgment seeking dismissal of certain affirmative defenses based on statutory immunities from federal antitrust law. The Court heard oral argument on the motions for summary judgment on February 22 and 23, 2016. The Court has not ruled on these motions.

 Allegations in Each Case. In all of the cases described above, the plaintiffs allege that the Company and certain other large domestic egg producers conspired to reduce the domestic supply of eggs in a concerted effort to raise the price of eggs to artificially high levels.  In each case, plaintiffs allege that all defendants agreed to reduce the domestic supply of eggs by: (a) agreeing to limit production; (b) manipulating egg exports; and (c) implementing industry-wide animal welfare guidelines that reduced the number of hens and eggs. 

The named plaintiffs in the remaining indirect purchaser putative class action seek treble damages under the statutes and common-law of various states and injunctive relief under the Sherman Act on behalf of themselves and all other putative class members in the United States. Although plaintiffs allege a class period starting in October, 2006 and running “through the present,” the Court denied the plaintiffs’ motion to certify classes seeking damages under the laws of 21 states and denied without prejudice the plaintiffs’ motion to certify an injunctive-relief class, although the plaintiffs have filed a renewed motion to certify an injunctive-relief class, as discussed above. 

Five of the original six non-class cases remain pending against the Company.  The principal plaintiffs in these cases are: The Kroger Co.; Publix Super Markets, Inc.; SUPERVALU, Inc.; Safeway, Inc.; Albertsons LLC; H.E. Butt Grocery Co.; The Great Atlantic & Pacific Tea Company, Inc.; Walgreen Co.; Hy-Vee, Inc.; Kraft Food Global, Inc., General Mills, Inc., Nestle USA, Inc., and The Kellogg Company.  In four of these remaining non-class cases, the plaintiffs seek treble damages and injunctive relief under the Sherman Act.  In the fifth remaining non-class case, the plaintiff seeks treble damages and injunctive relief under the Sherman Act and the Ohio antitrust act (known as the Valentine Act). 

The Pennsylvania court has entered a series of orders related to case management, discovery, class certification, summary judgment, and scheduling.  The Pennsylvania court has not set a trial date for any of the Company’s remaining consolidated cases (non-class and indirect purchaser cases).

The Company intends to continue to defend the remaining cases 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 these cases.  Accordingly, adjustments, if any, which might result from the resolution of these remaining legal matters, have not been reflected in the financial statements.

State of Oklahoma Watershed Pollution Litigation

On June 18, 2005, the State of Oklahoma filed suit, in the United States District Court for the Northern District of Oklahoma, against Cal-Maine Foods, Inc. and Tyson Foods, Inc. and affiliates, Cobb-Vantress, Inc., Cargill, Inc. and its affiliate, George’s, Inc. and its affiliate, Peterson Farms, Inc. and Simmons Foods, Inc. The State of Oklahoma claims that through the disposal of chicken litter the defendants have polluted the Illinois River Watershed. This watershed provides water to eastern Oklahoma. The complaint seeks injunctive relief and monetary damages, but the claim for monetary damages has been dismissed by the court. Cal-Maine Foods, Inc. discontinued operations in the watershed. Accordingly, we do not anticipate that Cal-Maine Foods, Inc. will be materially affected by the request for injunctive relief unless the court orders substantial affirmative remediation. Since the litigation began, Cal-Maine Foods, Inc. purchased 100% of the membership interests of Benton County Foods, LLC, which is an ongoing commercial shell egg operation within the Illinois River Watershed. Benton County Foods, LLC is not a defendant in the litigation.

The trial in the case began in September 2009 and concluded in February 2010. The case was tried to the court without a jury and the court has not yet issued its ruling. Management believes the risk of material loss related to this matter to be remote.

Florida Civil Investigative Demand

On November 4, 2008, the Company received an antitrust civil investigative demand from the Attorney General of the State of Florida. The demand seeks production of documents and responses to interrogatories relating to the production and sale of eggs and egg products. The Company is cooperating with this investigation and has, on three occasions, entered into an agreement with the State of Florida tolling the statute of limitations applicable to any supposed claims the State is investigating. No allegations of wrongdoing have been made against the Company in this matter.

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.

At this time, it is not possible for us to predict the ultimate outcome of the matters set forth above.

Description Of Rights And Privileges Of Capital Stock-Capital Structure Consists Of Common Stock And Class A Common Stock

14.   Description of Rights and Privileges of Capital Stock—Capital Structure Consists of Common Stock and Class A Common Stock

The Company has two classes of capital stock: Common Stock and Class A Common Stock. Holders of shares of the Company’s capital stock vote as a single class on all matters submitted to a vote of the stockholders, with each share of Common Stock entitled to one vote and each share of Class A Common Stock entitled to ten votes. The Common Stock and Class A Common Stock have equal liquidation rights and the same dividend rights.  In the case of any stock dividend, holders of Common Stock are entitled to receive the same percentage dividend (payable only in shares of Common Stock) as the holders of Class A Common Stock receive (payable only in shares of Class A Common Stock). Upon liquidation, dissolution, or winding-up of the Company, the holders of Common Stock are entitled to share ratably with the holders of Class A Common Stock in all assets available for distribution after payment in full of creditors. The Class A Common Stock may only be issued to Fred R. Adams, Jr., the Company’s Founder and Chairman Emeritus, and members of his immediate family, as defined. In the event any share of Class A Common Stock, by operation of law or otherwise is, or shall be deemed to be owned by any person other than Mr. Adams or a member of his immediate family, the voting power of such stock will be reduced from ten votes per share to one vote per share. Also, shares of Class A Common Stock shall be automatically converted into Common Stock on a share per share basis in the event the beneficial or record ownership of any such share of Class A Common Stock is transferred to any person other than Mr. Adams or a member of his immediate family. Each share of Class A Common Stock is convertible, at the option of its holder, into one share of Common Stock at any time. The holders of Common Stock and Class A Common Stock are not entitled to preemptive or subscription rights. In any merger, consolidation or business combination, the consideration to be received per share by holders of Common Stock must be identical to that received by holders of Class A Common Stock, except that if any such transaction in which shares of Capital Stock are distributed, such shares may differ as to voting rights to the extent that voting rights now differ among the classes of capital stock. No class of capital stock may be combined or subdivided unless the other classes of capital stock are combined or subdivided in the same proportion. No dividend may be declared and paid on Class A Common Stock unless the dividend is payable only to the holders of Class A Common Stock and a dividend is declared and paid to Common Stock concurrently.

On July 25, 2014, the Board of Directors approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to authorize an additional 60,000,000 shares of common stock and an additional 2,400,000 shares of Class A common stock.  The primary purpose of the amendment was to provide a sufficient number of authorized shares in order to effect a 2-for-1 stock split of the Company’s common stock and Class A common stock.  The amendment was approved by the Company’s stockholders at the Company’s annual meeting on October 3, 2014 and the Board of Directors approved the 2-for-1 stock split on the same day.  The new shares were distributed on October 31, 2014 to shareholders of record at the close of business on October 17, 2014. 

Unless otherwise noted, all prior period share and per share information contained in this report was adjusted to reflect the effect of the stock split.

Fair Value Measures

Fair Value Measures [Abstract]

Fair Value Measures

15.  Fair Value Measures

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 supported by little or no market activity and are significant to the fair value of the assets or liabilities.

The disclosure of fair value of certain financial assets and liabilities recorded at cost are as follows:

Cash and cash equivalents, accounts receivable, and accounts payable: 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. Estimated fair values are management’s estimates, which is a level 3 input; 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. The fair value of the Company’s debt is sensitive to changes in the general level of U.S. interest rates.  The Company maintains all of its debt as fixed rate in nature to mitigate the impact of fluctuations in interest rates.  Under its current policies, the Company does not use interest rate derivative instruments to manage its exposure to interest rate changes.  A one percent (1%) adverse move (i.e. decrease) in interest rates would adversely affect the net fair value of the Company’s debt by $300,000 at May 28, 2016.  The fair value and carrying value of the Company’s long-term debt were as follows (in thousands):

	May 28, 2016				May 30, 2015
	Carrying Value		Fair Value		Carrying Value		Fair Value

Our investment securities – available-for-sale classified as level 2 consist of certificates of deposit, time deposits, U.S. government and agency obligations, taxable and tax exempt municipal bonds, zero coupon municipal bonds, asset-backed securities, foreign government obligations, and corporate bonds with maturities of three months or longer when purchased. 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.  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 business acquisitions. Given the unobservable nature of these inputs, they are deemed to be Level 3fair value measurements.  During fiscal 2015 we recognized a $239,000 loss resulting from the increase in fair value of the contingent consideration. In fiscal 2014 we recognized a $4.4 million loss.  Both the losses were recognized in earnings as an increase of selling, general, and administrative expenses.  Changes in the fair value of contingent consideration obligations for fiscal 2016 were as follows (in thousands):

Proceeds from the sales of available-for-sale securities were $292.5 million, $146.8 million, and $108.1 million during fiscal 2016, 2015, and 2014, respectively. Gross realized gains on those sales during fiscal 2016, 2015, and 2014 were $131,000, $82,000, and $8,000, respectively. Gross realized losses on those sales during fiscal 2016, 2015, and 2014 were $110,000, $7,000, and $2,000, 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 (losses) net of tax on available-for-sale securities classified as current in the amount of $22,000, $(149,000), and $149,000 for the years ended May 28, 2016, May 30, 2015, and May 31, 2014, respectively, have been included in accumulated other comprehensive income (loss).  Unrealized holding gains (losses) net of tax on long term available-for-sale securities in the amount of $(31,000), $59,000 and $90,000 for the years ended May 28, 2016, May 30, 2015, and May 31, 2014 have been included in other comprehensive income (loss).

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.  Contractual maturities of investment securities at May 28, 2016, are as follows (in thousands):

Significant Accounting Policies [Abstract]

Principles Of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of Cal-Maine Foods, Inc. and its subsidiaries (“we,” “us,” “our,” or the “Company”).  All significant intercompany transactions and accounts have been eliminated in consolidation.

Business

Business

The Company is principally engaged in the production, processing and distribution of shell eggs. The Company’s operations are significantly affected by the market price fluctuation of its principal product, shell eggs, and the costs of its principal feed ingredients, corn, soybean meal, and other grains.

The Company sells shell eggs to a diverse group of customers, including national and local grocery store chains, club stores, foodservice distributors, and egg product consumers.  The Company’s sales are primarily in the southeastern, southwestern, mid-western and mid-Atlantic regions of the United States. Credit is extended based upon an evaluation of each customer’s financial condition and credit history and generally collateral is not required. Credit losses have consistently been within management’s expectations. Two customers, Wal-Mart and Sam’s Club, on a combined basis, accounted for 28.9%,  25.7% and 28.2% of the Company’s net sales in fiscal years 2016,  2015, and 2014, respectively.

Fiscal Year

Fiscal Year

The Company’s fiscal year-end is on the Saturday nearest May 31, which was May 28, 2016,  May 30, 2015, and May 31, 2014 for the most recent three fiscal years. All three years fiscal years were 52 week years.

Use Of Estimates

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash Equivalents

Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We maintain bank accounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000.  At May 28, 2016 and routinely throughout these years, the Company maintained cash balances with certain financial institutions in excess of federally insured amounts. The Company has not experienced any losses in such accounts.  The Company manages this risk through maintaining cash deposits and other highly liquid investments in high quality financial institutions. 

We primarily utilize a cash management system with a series of separate accounts consisting of lockbox accounts for receiving cash, concentration accounts where funds are moved to, and several zero-balance disbursement accounts for funding payroll and accounts payable. Checks issued, but not presented to the banks for payment, may result in negative book cash balances, which are included in accounts payable. AtMay 28, 2016, andMay 30, 2015, checks outstanding in excess of related book cash balances totaled zeroand$1.8 million, respectively.

Investment Securities

Investment Securities

Our investment securities are accounted for in accordance with ASC 320, “Investments-Debt and Equity Securities” (“ASC 320”).  The Company considers all of its investment securities for which there is a determinable fair market value and there are no restrictions on the Company's ability to sell within the next 12 months as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses reported as a separate component of stockholders' equity. We had unrealized gains, net of tax, of $363,000 and $372,000 at May 28, 2016 and May 30, 2015, respectively, which are included in the line item “Accumulated other comprehensive income (loss), net of tax” on our Consolidated Balance Sheet. Realized gains and losses are included in other income. The cost basis for realized gains and losses on available-for-sale securities is determined on the specific identification method.

At May 28, 2016 and May 30, 2015, we had $360.5 million and $250.0 million, respectively, of current investment securities available-for-sale consisting of commercial paper, time deposits, U.S. government obligations, government agency bonds, taxable municipal bonds, tax-exempt municipal bonds, zero coupon municipal bonds and corporate bonds with maturities of three months or longer when purchased. We classified these securities as current, because the amounts invested are available for current operations.  At May 28, 2016 and May 30, 2015 we had $1.9 million and $1.7 million, respectively, of investments in mutual funds which are considered long term and are a part of “Other Investments” in the Consolidated Balance Sheet.

Investment In Affiliates

Investment in Affiliates

The equity method of accounting is used when the Company has a 20% to 50% interest in other entities or when the Company exercises significant influence over the entity. Under the equity method, original investments are recorded at cost and adjusted by the Company’s share of undistributed earnings or losses of these entities. Nonmarketable investments in which the Company has less than a 20% interest and in which it does not have the ability to exercise significant influence over the investee are initially recorded at cost, and periodically reviewed for impairment.

Trade Receivables And Allowance For Doubtful Accounts

Trade Receivables and Allowance for Doubtful Accounts

Trade receivables are comprised primarily of amounts owed to the Company from customers, which amounted to $62.0 million at May 28, 2016 and $99.0 million at May 30, 2015. They are presented net of an allowance for doubtful accounts of $727,000 at May 28, 2016 and $513,000 at May 30, 2015. The Company extends credit to customers based upon an evaluation of each customer’s financial condition and credit history. Although credit risks associated with our customers are considered minimal, we routinely review our accounts receivable balances and make provisions for probable doubtful accounts. In circumstances where management is aware of a specific customer’s inability to meet its financial obligations to us (e.g., bankruptcy filings), a reserve is recorded to reduce the receivable to the amount expected to be collected. For all other customers, we recognize reserves for bad debt based on the length of time the receivables are past due, generally 100% for amounts more than 60 days past due. Collateral is generally not required. Credit losses have consistently been within management’s expectations. At both May 28, 2016 and May 30, 2015two customers accounted for approximately 29% and 24% of the Company’s trade accounts receivable, respectively.

Inventories

Inventories

Inventories of eggs, feed, supplies and livestock are valued principally at the lower of cost (first-in, first-out method) or market.

The cost associated with flocks, consisting principally of chick purchases, feed, labor, contractor payments and overhead costs, are accumulated during a growing period of approximately 22 weeks. Flock costs are amortized to cost of sales over the productive lives of the flocks, generally one to two years. Flock mortality is charged to cost of sales as incurred.

The Company does not disclose the gross cost and accumulated amortization with respect to its flock inventories since this information is not utilized by management in the operation of the Company.

Property, Plant And Equipment

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is provided by the straight-line method over the estimated useful lives, which are 15 to 25 years for buildings and improvements and 3 to 12 years for machinery and equipment. Repairs and maintenance are expensed as incurred. Expenditures that increase the value or productive capacity of assets are capitalized. When property, plant, and equipment are retired, sold, or otherwise disposed of, the asset’s carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in operations. The Company capitalizes interest cost incurred on funds used to construct property, plant, and equipment as part of the asset to which it relates, and is amortized over the asset’s estimated useful life.

Impairment Of Long-Lived Assets

Impairment of Long-Lived Assets

The Company reviews the carrying value of long-lived assets, other than goodwill, for impairment whenever events and circumstances indicate the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. In cases where expected future cash flows (undiscounted and without interest charges) are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. The factors considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the property is used, and the effects of obsolescence, demand, competition, and other economic factors.

Intangible Assets

Intangible Assets

Included in other intangible assets are separable intangible assets acquired in business acquisitions, which include franchise fees, non-compete agreements and customer relationship intangibles, and are amortized over their estimated useful lives of 3 to 25 years.   The gross cost and accumulated amortization of intangible assets are removed when the recorded amounts have been fully amortized and the asset is no longer in use or the contract has expired.  Included in other long-lived assets are loan acquisition costs, which are amortized over the life of the related loan.

Goodwill

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill is evaluated for impairment annually by first performing a qualitative assessment to determine whether a quantitative goodwill test is necessary.  After assessing the totality of events or circumstances, if we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform additional quantitative tests to determine the magnitude of any impairment.

Accrued Self Insurance

Accrued Self Insurance

We use a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for health and welfare, workers’ compensation, auto liability and general liability risks. Liabilities associated with our risks retained are estimated, in part, by considering claims experience, demographic factors, severity factors and other actuarial assumptions. 

Dividends

Dividends

Cal-Maine 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 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 65th 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, 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.  Dividends payable were zero and $15.4 million at May 28, 2016 and May 30, 2015, respectively. These amounts represent accrued unpaid dividends applicable to the Company’s fourth quarter net income for each fiscal year.

Treasury Stock

Treasury Stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.  The grant of restricted stock through the Company’s share-based compensation plans is funded through the issuance of treasury stock.  Gains and losses on the subsequent reissuance of shares in accordance with the Company’s share-based compensation plans are credited or charged to paid-in capital in excess of par value using the average-cost method.

Revenue Recognition And Delivery Costs

Revenue Recognition and Delivery Costs

The Company recognizes revenue only when all of the following criteria have been met:

· Persuasive evidence of an arrangement exists;

· Delivery has occurred;

· The fee for the arrangement is determinable; and

· Collectability is reasonably assured.

The Company believes the above criteria are met upon delivery and acceptance of the product by our customers. Costs to deliver product to customers are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income and totaled $49.6 million, $47.0 million, and $43.0 million in fiscal years 2016,  2015, and 2014, respectively.  Sales revenue reported in the accompanying consolidated statements of income is reduced to reflect estimated returns and allowances.  The Company records an estimated sales allowance for returns and discounts at the time of sale using historical trends based on actual sales returns and sales.

Sales Incentives Provided To Customers

Sales Incentives provided to Customers

The Company periodically provides incentive offers to its customers to encourage purchases. Such offers include current discount offers (e.g., percentage discounts off current purchases), inducement offers (e.g., offers for future discounts subject to a minimum current purchase), and other similar offers. Current discount offers, when accepted by customers, are treated as a reduction to the sales price of the related transaction, while inducement offers, when accepted by customers, are treated as a reduction to sales price based on estimated future redemption rates. Redemption rates are estimated using the Company’s historical experience for similar inducement offers. Current discount and inducement offers are presented as a net amount in ‘‘Net sales.’’

Advertising Costs

Advertising Costs

The Company expensed advertising costs as incurred of $10.3 million, $9.3 million, and $8.5 million in fiscal 2016,  2015, and 2014, respectively.  

Income Taxes

Income Taxes

Income taxes are provided using the liability method. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company’s policy with respect to evaluating uncertain tax positions is based upon whether management believes it is more likely than not the uncertain tax positions will be sustained upon review by the taxing authorities.  The tax positions must meet the more-likely-than-not recognition threshold with consideration given to the amounts and probabilities of the outcomes that could be realized upon settlement using the facts, circumstances and information at the reporting date.  The Company will reflect only the portion of the tax benefit that will be sustained upon resolution of the position and applicable interest on the portion of the tax benefit not recognized. The Company shall initially and subsequently measure the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.    Based upon management’s assessment, there are no uncertain tax positions expected to have a material impact on the Company’s consolidated financial statements.

Stock Based Compensation

Stock Based Compensation

We account for share-based compensation in accordance with ASC 718, “Compensation-Stock Compensation” (“ASC 718”).  ASC 718 requires all share-based payments to employees, including grants of employee stock options, restricted stock and performance-based shares to be recognized in the income statement based on their fair values. ASC 718 requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow.  See Note 11: Stock Compensation Plans for more information.

Net Income Per Common Share

Net Income per Common Share

Basic net income per share is based on the weighted average common and Class A shares outstanding. Diluted net income per share includes any dilutive effects of stock options outstanding and unvested restricted shares.

Basic net income per share was calculated by dividing net income by the weighted-average number of common and Class A shares outstanding during the period.  Diluted net income 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 stock options and unvested restricted shares.  The computations of basic net income per share and diluted net income per share are as follows (in thousands):

	May 28, 2016	May 30, 2015	May 31, 2014
Net income attributable to Cal-Maine Foods, Inc.	$          316,041	$        161,254	$        109,207

Diluted	$                6.53	$              3.33	$              2.26

Contingencies

Contingencies

Certain conditions may exist as of the date the financial statements are issued that may result in a loss to the Company but which will only be resolved when one or more future events occur or fail to occur. The Company’s management and its legal counsel assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or unasserted claims that may result in such proceedings, the Company’s legal counsel evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates it is probable that a material loss has been incurred and the amount of the liability can be estimated, the estimated liability would be 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. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the nature of the guarantee would be disclosed. 

The Company expenses the costs of litigation as they are incurred.

Impact Of Recently Issued Accounting Standards

Impact of Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer in an amount that reflects the consideration that is expected to be received for those goods or services.  In August 2015, FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company does notexpectASU 2014-09to have a material impacton the consolidated financial statement presentation.

In November 2015, the FASB issued ASU 2015-17, Income Taxes – Balance Sheet Classification of Deferred Taxes.  The purpose of the standard is to simplify the presentation of deferred taxes on a classified balance sheet.  Under current GAAP, deferred income tax assets and liabilities are separated into current and noncurrent amounts in the balance sheet.  The amendments in ASU 2015-17 require that all deferred tax assets and liabilities be classified as noncurrent in the balance sheet.  ASU 2015-17 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods.  Early application is permitted.  The Company adopted ASU 2015-17 during the fourth quarter of fiscal 2016 and retrospectively applied it to all reported periods.  Adoption of ASU 2015-17 impacted our previously reported current ratio for fiscal 2015 by increasing it from 3.86 as reported in the prior year to 5.01 as reported in this report.

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 guidance will require balance sheet recognition for assets and liabilities associated with rights and obligations created by leases with terms greater than twelve months.  ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods.  Early adoption is permitted.  The Company is currently evaluating the impact of ASU 2016-02 on its financial statements and presentation.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Compensation Accounting. ASU 2016-09 requires that excess tax benefits are recorded on the income statement as opposed to additional paid-in-capital, and treated as an operating activity on the statement of cash flows. ASU 2016-09 also allows companies to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted.  The Company does notexpectASU 2016-09to have a material impacton the consolidated financial statement presentation.
