Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

1. Organization, Basis of Presentation and Summary of Significant Accounting Policies

Organization

Landec Corporation and its subsidiaries (“Landec” or the “Company”) design, develop, manufacture and sell polymer products for food and agricultural products, medical devices and licensed partner applications that incorporate Landec’s patented polymer technologies. The Company has two proprietary polymer technology platforms: 1) Intelimer® polymers, and 2) hyaluronan (“HA”) biopolymers. The Company’s HA biopolymers are proprietary in that they are specially formulated for specific customers to meet strict regulatory requirements. The Company’s polymer technologies, along with its customer relationships and trade names, are the foundation, and a key differentiating advantage upon which Landec has built its business. The Company sells specialty packaged fresh-cut vegetables and whole produce to retailers and club stores, primarily in the United States, Asia and Canada, through its Apio, Inc. (“Apio”) subsidiary, HA-based biomaterials through its Lifecore Biomedical, Inc. (“Lifecore”) subsidiary.

Basis of Presentation

The accompanying unaudited consolidated financial statements of Landec have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring accruals) have been made which are necessary to present fairly the financial position at November 25, 2012 and the results of operations and cash flows for all periods presented. Although Landec believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information normally included in financial statements and related footnotes prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission. The accompanying financial data should be reviewed in conjunction with the audited financial statements and accompanying notes included in Landec's Annual Report on Form 10-K for the fiscal year ended May 27, 2012.

The results of operations for the six months ended November 25, 2012 are not necessarily indicative of the results that may be expected for an entire fiscal year because there is some seasonality in Apio’s food business, particularly, Apio’s Food Export business and the order patterns of Lifecore’s customers which may lead to significant fluctuations in Landec’s quarterly results of operations.

Basis of Consolidation

The consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles and include the accounts of Landec and its subsidiaries, Apio and Lifecore. All material inter-company transactions and balances have been eliminated.

Arrangements that are not controlled through voting or similar rights are reviewed under the guidance for variable interest entities (“VIEs”). A company is required to consolidate the assets, liabilities and operations of a VIE if it is determined to be the primary beneficiary of the VIE.

An entity is a VIE and subject to consolidation, if by design: a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by any parties, including equity holders or b) as a group the holders of the equity investment at risk lack any one of the following three characteristics: (i) the power, through voting rights or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity. The Company reviewed the consolidation guidance and concluded that the non-public companies in which the Company holds equity investments are not VIEs.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make certain estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates that require management’s most significant and subjective judgments include revenue recognition; sales returns and allowances; recognition and measurement of current and deferred income tax assets and liabilities; the assessment of recoverability of long-lived assets; the valuation of intangible assets and inventory; the valuation of investments; and the valuation and recognition of stock-based compensation.

These estimates involve the consideration of complex factors and require management to make judgments. The analysis of historical and future trends can require extended periods of time to resolve and is subject to change from period to period. The actual results may differ from management’s estimates.

Cash, Cash Equivalents and Marketable Securities

Cash and Cash Equivalents

The Company records all highly liquid securities with three months or less from date of purchase to maturity as cash equivalents. Cash equivalents consist mainly of certificate of deposits (CDs), money market funds and U.S. Treasuries. The market value of cash equivalents approximates their historical cost given their short-term nature.

Marketable Securities

Short-term marketable securities consist of CDs that are FDIC insured and single A or better rated municipal bonds with original maturities of more than three months at the date of purchase regardless of the maturity date as the Company views the funds within its portfolio as available for use in its current operations. The Company classifies all debt securities with readily determined market values as “available for sale”. The aggregate amount of CDs included in marketable securities at November 25, 2012 and May 27, 2012 was $1.6 million and zero, respectively. The contractual maturities of the Company’s marketable securities that are due in less than one year represented $1.7 million and zero of its marketable securities as of November 25, 2012 and May 27, 2012, respectively. The contractual maturities of the Company’s marketable securities that are due in one to two years represented $250,000 and zero of its marketable securities as of November 25, 2012 and May 27, 2012, respectively. Investments in marketable securities are carried at fair market value. Unrealized gains and losses are reported as a component of stockholders’ equity. The cost of debt securities is adjusted for amortization of premiums and discounts to maturity. This amortization is recorded to interest income. Realized gains and losses on the sale of available-for-sale securities are also recorded to interest income and were not significant for the three and six months ended November 25, 2012 and November 27, 2011. During the three and six months ended November 25, 2012, the Company did not sell any marketable securities. During the three and six months ended November 27, 2011, the Company sold $6.8 million of marketable securities. The cost of securities sold is based on the specific identification method.

Financial Instruments

The Company’s financial instruments are primarily composed of marketable securities, commercial-term trade payables, grower advances, and notes receivable, as well as long-term notes receivables and debt instruments. For short-term instruments, the historical carrying amount approximates the fair value of the instrument. The fair value of long-term debt and lines of credit approximates their carrying value. Fair values for long-term financial instruments not readily marketable are estimated based upon discounted future cash flows at prevailing market interest rates. Based on these assumptions, management believes the fair market values of the Company’s financial instruments are not materially different from their recorded amounts as of November 25, 2012 or May 27, 2012.

Investments in Non-Public Companies

The Company’s investment in Aesthetic Sciences Corporation (“Aesthetic Sciences”) is carried at cost and adjusted for impairment losses. Since there is no readily available market value information, the Company periodically reviews this investment to determine if any other than temporary declines in value have occurred based on the financial stability and viability of Aesthetic Sciences.

On February 15, 2011, the Company made an investment in Windset Holdings 2010 Ltd., a Canadian corporation (“Windset”), which is reported as an investment in non-public company, fair value, in the accompanying Consolidated Balance Sheets as of November 25, 2012 and May 27, 2012. The Company has elected to account for its investment in Windset under the fair value option (see Note 4).

Intangible Assets

The Company’s intangible assets are comprised of customer relationships with a finite estimated useful life of twelve to thirteen years and trade names and goodwill with indefinite lives.

Finite-lived intangible assets are reviewed for possible impairment whenever events or changes in circumstances occur that indicate that the carrying amount of an asset (or asset group) may not be recoverable. Indefinite lived intangible assets are reviewed for impairment at least annually by comparing the fair value of the asset to its carrying value to determine if there has been an impairment. Goodwill is reviewed for impairment at least annually by comparing the fair value of the related reporting unit to its carrying value to determine if there has been an impairment.

Fair Value Measurements

The Company uses fair value measurement accounting for financial assets and liabilities and for financial instruments and certain other items at fair value. The Company has elected the fair value option for its investment in a non-public company (see Note 4). The Company has not elected the fair value option for any of its other eligible financial assets or liabilities.

The accounting guidance established a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows:

Level 1 –

observable inputs such as quoted prices for identical instruments in active markets.

Level 2 –

inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data.

Level 3 –

unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.

As of November 25, 2012, the Company held certain assets and liabilities that are required to be measured at fair value on a recurring basis, including cash equivalents, marketable securities, interest rate swap and liability for contingent consideration in connection with the acquisition of GreenLine and its minority interest investment in Windset.

The fair value of the Company’s cash equivalents and marketable securities is determined based on observable inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized its cash equivalents and marketable securities as Level 1.

The fair value of the Company’s interest rate swap is determined based on model inputs that can be observed in a liquid market, including yield curves, and is categorized as Level 2 inputs.

The fair value of the Company’s liability for contingent consideration is based on significant inputs not observed in the market and thus represents a Level 3 measurement. The Company determined the fair value of the liability for the contingent consideration as of May 27, 2012, based on a probability-weighted discounted cash flow analysis, as further discussed in Note 2 to the Consolidated Financial Statements.

The Company has elected the fair value option of accounting for its investment in Windset. The fair value of the Company’s investment in Windset utilizes significant unobservable inputs in the discounted cash flow models, including projected cash flows, growth rates and discount rates. As a result, the Company’s investment in Windset is considered to be a Level 3 measurement investment, as further discussed in Note 4. The change in the fair market value of the Company’s investment in Windset for the three and six months ended November 25, 2012 was due to the Company’s 20.1% minority interest in the change in the fair market value of Windset during those periods. In determining the fair value of the investment in Windset, the Company utilizes the following significant unobservable inputs in the discounted cash flow models:

	At November 25, 2012			At May 27, 2012
Revenue growth rates	3%	to	10%	3%	to	24%
Expense growth rates	3%	to	8%	3%	to	18%
Income tax rates	8%	to	25%		25%
Discount rates	16%	to	27%	16%	to	27%

The revenue growth, expense growth and income tax rate assumptions, consider the Company's best estimate of the trends in those items over the discount period. The discount rate assumption takes into account the risk-free rate of return, the market equity risk premium and the Company’s specific risk premium and then applies an additional discount for lack of liquidity of the underlying securities. The discounted cash flow valuation model used by the Company has the following sensitivity to changes in inputs and assumptions (in thousands):

	Impact on value of Windset investment as of November 25, 2012
10% increase in revenue growth rates	$	1,000
10% increase in expense growth rates	$	(600	)
10% increase in income tax rates	$	(100	)
10% increase in discount rates	$	(250	)

Imprecision in estimating unobservable market inputs can affect the amount of gain or loss recorded for a particular position. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

The following table summarizes the fair value of the Company’s assets and liabilities that are measured at fair value on a recurring basis as of November 25, 2012 and May 27, 2012 (in thousands):

	Fair Value at November 25, 2012						Fair Value at May 27, 2012

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title, and acceptance, if applicable, as well as fixed pricing and probable collectibility. The Company records pricing allowances, including discounts based on arrangements with customers, which is recognized in revenue as a reduction to both accounts receivable and net revenue.

When a sales arrangement contains multiple elements, the Company allocates revenue to each element based on a selling price hierarchy. The relative selling price for a deliverable is based on its vendor-specific objective evidence (VSOE), if available, third-party evidence (TPE), if VSOE is not available, or estimated selling price if neither VSOE nor TPE is available. The Company then recognizes revenue on each deliverable in accordance with its policies for product and service revenue recognition. The Company is ot typically able to determine VSOE or TPE, and therefore, uses estimated selling prices to allocate revenue between the elements of the arrangement.

The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or future performance obligations or subject to customer-specific cancellation rights. The Company evaluates each deliverable in an arrangement to determine whether they represent separate units of accounting. A deliverable constitutes a separate unit of accounting when it has stand-alone value, and for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by the Company. The Company considers a deliverable to have stand-alone value if the product or service is sold separately by the Company or another vendor or could be resold by the customer. Further, the revenue arrangements generally do not include a general right of return relative to the delivered products. Where the aforementioned criteria for a separate unit of accounting are not met, the deliverable is combined with the undelivered element(s) and treated as a single unit of accounting for the purposes of allocation of the arrangement consideration and revenue recognition. The Company allocates the total arrangement consideration to each separable element of an arrangement based upon the relative selling price of each element. Allocation of the consideration is determined at arrangement inception on the basis of each unit’s relative selling price. In instances where the Company has not established fair value for any undelivered element, revenue for all elements is deferred until delivery of the final element is completed and all recognition criteria are met.

Reclassifications

Certain reclassifications have been made to prior period financial statements to conform to the current period presentation.

New Accounting Pronouncements

Intangibles-Goodwill and Other

In September 2011, the FASB issued new guidance that will allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under this amendment, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendment includes a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The guidance is effective for fiscal years beginning after December 15, 2011 with early adoption permitted. The adoption of this update did not have a material impact on the Company’s consolidated financial statements.

Presentation of Comprehensive Income

In December 2011, the FASB issued new guidance that improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income by eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments in this standard require that all non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under either method, adjustments must be displayed for items that are reclassified from other comprehensive income ("OCI") to net income, in both net income and OCI. The standard does not change the current option for presenting components of OCI gross or net of the effect of income taxes, provided that such tax effects are presented in the statement in which OCI is presented or disclosed in the notes to the financial statements. Additionally, the standard does not affect the calculation or reporting of earnings per share. For public entities, the amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and are to be applied retrospectively, with early adoption permitted. The Company adopted this standard beginning in fiscal year 2013.

Fair Value Measurement

In May 2011, the FASB issued new guidance effective for annual reporting periods beginning after December 15, 2011. This guidance amends certain accounting and disclosure requirements related to fair value measurements. Additional disclosure requirements in the update include: (1) for Level 3 fair value measurements, quantitative information about unobservable inputs used, a description of the valuation processes used by the entity, and a qualitative discussion about the sensitivity of the measurements to changes in the unobservable inputs; (2) for an entity’s use of a nonfinancial asset that is different from the asset’s highest and best use, the reason for the difference; (3) for financial instruments not measured at fair value but for which disclosure of fair value is required, the fair value hierarchy level in which the fair value measurements were determined; and (4) the disclosure of all transfers between Level 1 and Level 2 of the fair value hierarchy. The Company adopted this standard beginning in fiscal year 2013.

Disclosures about Offsetting Assets and Liabilities

In November 2011, the FASB issued new guidance effective for annual reporting periods beginning January 1, 2013. This guidance amends the disclosure requirements around offsetting to enable users of the financial statements to understand the effect of those arrangements on its financial position. Entities are required to disclose both gross and net information about the instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

Business Combination Disclosure [Text Block]

2. Acquisitions

GreenLine Holding Company

On April 23, 2012 (the “GreenLine Acquisition Date”), Apio acquired all of the outstanding equity of GreenLine Holding Company (“GreenLine”) pursuant to a Stock Purchase Agreement (the “GreenLine Purchase Agreement”) in order to expand its product offerings and enter into new markets such as foodservice. GreenLine, headquartered in Bowling Green, Ohio, was a privately-held company and is the leading processor and marketer of value-added, fresh-cut green beans in North America. GreenLine has four processing plants one each in Ohio, Pennsylvania, Florida and California and distribution centers in New York and South Carolina.

Under the GreenLine Purchase Agreement, the aggregate consideration paid at closing consisted of $62.9 million in cash, including $4.7 million that is held in an escrow account to secure Landec’s indemnification rights with respect to certain matters, including breaches of representations, warranties and covenants. In addition, the GreenLine Purchase Agreement included a potential earn out payment up to $7.0 million in the event that GreenLine achieves certain revenue targets during calendar year 2012. The earn out was comprised of $4.0 million for achieving a certain revenue target during calendar year 2012, and up to an additional $3.0 million for exceeding the revenue target by $3.0 million or more. During fiscal year 2012, the Company performed an analysis of projected revenues for GreenLine and concluded at that time that there was a reasonable probability that GreenLine would meet, but not exceed, the initial revenue target and therefore, the Company recorded a $3.9 million liability as of May 27, 2012, representing the present value of the fair market value of the expected earn out payment. As a result of the severe drought in the Midwest during 2012, lower than expected results from new product launches and new planned business not being realized, during the second quarter the Company determined that it is no longer probable that GreenLine will achieve the earn out revenue target and, therefore, the Company has reversed the $3.9 million liability recorded for the earn out and has recorded a corresponding credit to the “Change in value of contingent consideration” in its Consolidated Condensed Statements of Income for the three and six months ended November 25, 2012.

The acquisition date fair value of the total consideration transferred was $66.8 million, which consisted of the following (in thousands):

Cash	$	62,900
Contingent consideration		3,933
Total	$	66,833

The assets and liabilities of GreenLine were recorded at their respective estimated fair values as of the date of the acquisition using generally accepted accounting principles for business combinations. The excess of the purchase price over the fair value of the net identifiable assets acquired has been allocated to goodwill. Goodwill represents a substantial portion of the acquisition proceeds because of the workforce in-place at acquisition and because of GreenLine’s long history and future prospects. Management believes that there is further growth potential by extending GreenLine’s product lines into new channels, such as club stores.

The following table summarizes the estimated fair values of GreenLine’s assets acquired and liabilities assumed and related deferred income taxes, effective April 23, 2012, the date the Company obtained control of GreenLine (in thousands).

Accounts receivable, net	$	7,057
Inventories, net		1,409
Property and equipment		11,669
Other tangible assets		306
Intangible assets		43,500
Total identifiable assets acquired		63,941
Accounts payable and other liabilities		(8,391	)
Deferred taxes		(1,875	)
Total liabilities assumed		(10,266	)
Net identifiable assets acquired		53,675
Goodwill		13,158
Net assets acquired	$	66,833

The Company used a combination of the market and cost approaches to estimate the fair values of the GreenLine assets acquired and liabilities assumed. During the measurement period (which is not to exceed one year from the acquisition date), the Company is required to retrospectively adjust the provisional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets or liabilities as of that date. No adjustments were made to the fair values of GreenLine assets acquired or liabilities assumed during the six months ended November 25, 2012. The Company has finalized the fair values of the acquired assets and assumed liabilities and has completed the purchase price allocation as of November 25, 2012.

Intangible Assets

The fair value of indefinite and finite-lived intangible assets was determined using a discounted cash flow model, under an income valuation methodology, based on management’s five-year projections of revenues, gross profits and operating profits by fiscal year and assumes a 40% effective tax rate for each year. Management takes into account the historical trends of GreenLine and the industry categories in which GreenLine operates along with inflationary factors, current economic conditions, new product introductions, cost of sales, operating expenses, capital requirements and other relevant data when developing its projection. The Company believes that the level and timing of projected cash flows appropriately reflect market participant assumptions. The projected cash flows from these intangibles were based on key assumptions such as estimates of revenues and operating profits related to the intangibles over their respective forecast periods. The resultant cash flows were then discounted using a rate the Company believes is appropriate given the inherent risks associated with each intangible asset and reflect market participant assumptions.

The Company identified two intangible assets in connection with the GreenLine acquisition: trade names and trademarks valued at $36.0 million, which is considered to be an indefinite life asset and therefore, will not be amortized; and customer base valued at $7.5 million with a thirteen year useful life. The trade name/trademark intangible asset was valued using the relief from royalty valuation method and the customer relationship intangible asset was valued using the distributor method.

Goodwill

The excess of the consideration transferred over the fair values assigned to the assets acquired and liabilities assumed was $13.2 million on the closing date, which represents the goodwill amount resulting from the acquisition which can be attributable to GreenLine’s long history, future prospects and the expected operating synergies from combining GreenLine with Apio’s fresh-cut, value-added vegetable business. None of the goodwill is expected to be deductible for income tax purposes. The Company will test goodwill for impairment on an annual basis or sooner, if indicators of impairment are present.

Deferred Tax Liabilities

The $1.9 million of net deferred tax liabilities resulting from the acquisition was primarily related to the difference between the book basis and tax basis of the intangible assets and net operating losses that were assumed by the Company in the acquisition.

Lifecore Biomedical, Inc.

On April 30, 2010, the Company acquired all of the common stock of Lifecore Biomedical, Inc. (“Lifecore”) pursuant to a Stock Purchase Agreement (“Lifecore Purchase Agreement”) in order to expand its product offerings and enter into new markets. Lifecore was a privately-held hyaluronan-based biomaterials company located in Chaska, Minnesota. Lifecore is principally involved in the development and manufacture of products utilizing hyaluronan, a naturally occurring polysaccharide that is widely distributed in the extracellular matrix of connective tissues in both animals and humans.

Under the Lifecore Purchase Agreement, the Company paid to the former Lifecore stockholder at closing $40.0 million in cash, which included $6.6 million held in an escrow account. Half of the escrow or $3.3 million was released and paid to the former Lifecore shareholder in May 2011. The other half was released and paid to the former Lifecore shareholder in May 2012. In addition to the cash consideration paid to the former shareholder of Lifecore, the Lifecore Purchase Agreement included an earn out payment of up to an additional $10.0 million based on Lifecore achieving certain revenue targets in calendar years 2011 and 2012. These revenue targets were achieved in calendar year 2011 and the $10.0 million earn out payment was paid by the Company to the former shareholder of Lifecore on May 29, 2012.

3. Sale of Landec Ag

On June 24, 2012, Landec entered into a stock purchase agreement and two licensing agreements (see Note 4) with INCOTEC® Coating and Seed Technology Companies (“INCOTEC”), a leading provider of seed and coating technology products and services to the seed industry.

In the stock purchase agreement, Landec sold its equity interest in its seed subsidiary, Landec Ag LLC, to INCOTEC for $600,000, which resulted in a gain of $400,000. Under accounting guidance, because the stock purchase agreement was entered into at the same time the license agreements were consummated (a multiple element agreement), a portion of the gain, or $300,000, has been deferred and will be recognized as revenue monthly from the sale date over the seven year life of the Pollinator Plus® license agreement (see Note 5). The remaining $100,000 of the gain was recognized during the first quarter of fiscal year 2013.

4. Investments in non-public companies

In December 2005, Landec entered into a licensing agreement with Aesthetic Sciences for the exclusive rights to use Landec's IntelimerÒ materials technology for the development of dermal fillers worldwide under the agreement. The Company received shares of preferred stock in exchange for the license with a valuation of $1.8 million. Aesthetic Sciences sold the rights to its Smartfil™ Injector System on July 16, 2010. Landec has evaluated its investment in Aesthetic Sciences for impairment, utilizing a discounted cash flow analysis under the terms of the purchase agreement. Based on the terms of the sale, the Company determined that its investment was other than temporarily impaired and therefore, recorded an impairment charge of $1.0 million as of May 30, 2010. The Company’s carrying value of its investment in Aesthetic Sciences is $793,000 as of November 25, 2012 and May 27, 2012. No additional impairment has been determined for the Company’s investment in Aesthetic Sciences.

On February 15, 2011, Apio entered into a share purchase agreement (the “Windset Purchase Agreement”) with Windset. Pursuant to the Windset Purchase Agreement, Apio purchased 150,000 senior preferred shares for $15 million and 201 common shares for $201 that were issued by Windset (the “Purchased Shares”). The Company’s common shares represent a 20.1% interest in Windset. The non-voting senior preferred shares yield a cash dividend of 7.5% annually. The dividend is payable within 90 days of each anniversary of the execution of the Windset Purchase Agreement and the first dividend payment of $1.1 million was made in May 2012. The Windset Purchase Agreement includes a put and call option, which can be exercised on the sixth anniversary of the Windset Purchase Agreement whereby Apio can exercise the put to sell its Purchased Shares to Windset, or Windset can exercise the call to purchase the Purchased Shares from Apio, in either case, at a price equal to 20.1% of the appreciation in the fair market value of Windset from the date of the Company’s investment through the put and call date, plus the purchase price of the Purchased Shares. Under the terms of the arrangement with Windset, the Company is entitled to designate one of five members on the Board of Directors of Windset.

In accordance with accounting guidance, the investment in Windset does not qualify for equity method accounting as the investment does not meet the criteria of in-substance common stock due to returns through the annual dividend on the non-voting senior preferred shares that are not available to the common stock holders. As the put and call options require the Purchased Shares to be put or called in equal proportions, the Company has deemed that the investment, in substance, should be treated as a single security for purposes of accounting. The Company has adopted fair value option in the accounting for its investment in Windset effective on the acquisition date. The fair value of the Company’s investment in Windset utilizes significant unobservable inputs in the discounted cash flow models, including projected cash flows, growth rates and discount rates (see Note 1) and is therefore considered a Level 3 for fair value measurement purposes. The Company believes that reporting its investment at fair value provides its investors with useful information on the performance of the Company’s investment and the anticipated appreciation in value as Windset expands its business.

The fair value of the Company’s investment in Windset was determined utilizing a discounted cash flow model based on projections developed by Windset, and considers the put and call conversion options. These features impact the duration of the cash flow utilized to derive the estimated fair value of the investment. Assumptions included in the discounted cash flow model will be evaluated quarterly based on Windset’s actual and projected operating results to determine the change in fair value.

During the three and six months ended November 25, 2012 and November 27, 2011, the Company recorded $281,000 and $563,000, respectively, in dividend income. The change in the fair market value of the Company’s investment in Windset for the three months ended November 25, 2012 and November 27, 2011 was $1.0 million and $1.1 million, respectively, and is included in other income in the Consolidated Statements of Income. The change in the fair market value of the Company’s investment in Windset for the six months ended November 25, 2012 and November 27, 2011 was $5.3 million and $1.2 million, respectively, and is included in other income in the Consolidated Statements of Income.

The Company also entered into an exclusive license agreement with Windset, which was executed in June 2010, prior to contemplation of Apio’s investment in Windset (see Note 5).

On December 1, 2006, Landec entered into a five-year co-exclusive technology license and polymer supply agreement (“the Monsanto Agreement”) with Monsanto Company (“Monsanto”) for the use of Landec’s Intellicoat polymer seed coating technology. On December 1, 2011, Monsanto terminated the Monsanto Agreement and paid the Company a $4 million termination fee and all rights to the Intellicoat seed coating technology reverted to Landec.

For the three and six months ended November 27, 2011, Landec recognized $1.35 million and $2.7 million, respectively, in license revenues from the Monsanto Agreement.

INCOTEC

In connection with the sale of Landec Ag to INCOTEC on June 24, 2012 (see Note 3), Landec entered into a seven-year exclusive technology license and polymer supply agreement with INCOTEC for the use of Landec’s Intellicoat® polymer seed coating technology for male inbred corn which is sold under the Pollinator Plus label. This license does not include the use of Intellicoat for the controlled release of an active ingredient for agricultural applications which was retained by Landec. Landec will be the exclusive supplier of Pollinator Plus polymer to INCOTEC during the term of the license agreement. Landec will receive a royalty equal to 20% of the revenues realized by INCOTEC from the sale of or sublicense of Pollinator Plus coatings during the first four years of the agreement and 10% for the last three years of the agreement.

On June 24, 2012, Landec also entered into a five-year exclusive technology license and polymer supply agreement with INCOTEC for the joint development of new polymer and unique coatings for use in seed treatment formulations. In this agreement, Landec will receive a value share which will be mutually agreed to by both parties prior to each application being developed.

Air Products

In March 2006, Landec entered into an exclusive license and research and development agreement with Air Products and Chemicals, Inc. (“Air Products”). In accordance with the agreement, Landec receives 40% of the direct profit generated from the sale of products by Air Products occurring after April 1, 2007, that incorporate Landec’s Intelimer materials.

Chiquita

In September 2007, the Company amended its licensing and supply agreement with Chiquita Brands International, Inc. (“Chiquita”). Under the terms of the amendment, the license for bananas was expanded to include additional exclusive fields using Landec’s BreatheWay® packaging technology, and a new exclusive license was added for the sale and marketing of avocados and mangos using Landec’s BreatheWay packaging technology. The agreement with Chiquita has been renewed through December 2016 and requires Chiquita to pay annual gross profit minimums to Landec in order for Chiquita to maintain its exclusive license for bananas, avocados and mangos. Under the terms of the agreement, Chiquita must notify Landec before December 1st of each year whether it is going to maintain its exclusive license for the following calendar year and thus agree to pay the minimums for that year. Landec was notified in November 2012 that Chiquita has chosen to not maintain its exclusive license for calendar year 2013 and thus will not be required to pay the minimum gross profit for calendar year 2013. As a result, the agreement has reverted to a non-exclusive agreement in which Chiquita will pay the Company for membranes purchased on a per unit sales basis and the Company is now entitled to sell its BreatheWay packaging technology for bananas, avocados and mangos to others.

Windset

In June 2010, Apio entered into an exclusive license agreement with Windset for Windset to utilize Landec’s proprietary breathable packaging to extend the shelf life of greenhouse grown cucumbers, peppers and tomatoes (“Exclusive Products”). In accordance with the agreement, Apio received and recorded a one-time upfront research and development fee of $100,000 and will receive license fees equal to 3% of net revenue of the Exclusive Products utilizing the proprietary breathable packaging technology, with or without the BreatheWay® trademark. The ongoing license fees are subject to annual minimums of $150,000 for each of the three types of exclusive product as each is added to the agreement. As of November 25, 2012, two products have been added to the agreement.

Nitta

In July 2012, the Company entered into a research and development agreement with Nitta Corporation, a Japanese company, to develop additional uses of the Company’s adhesive polymer technology for electronics. For the three and six months ended November 25, 2012, the Company recognized $103,000 and $138,000, respectively, in research and development revenues from this agreement. The agreement was amended in November 2012, to extend and expand the scope of the work under the agreement for another six months. The Company expects to recognize an additional $550,000 in research and development revenue under the amended agreement during the second half of fiscal year 2013.

Income Tax Disclosure [Text Block]

8. Income Taxes

The provision for income taxes for the three and six months ended November 25, 2012 was $2.9 million and $5.5 million, respectively. The effective tax rate for the six months ended November 25, 2012 was 29% compared to 38% for the same periods in fiscal year 2012. The effective tax rate for the six months ended November 25, 2012 differs from the statutory federal income tax rate of 35% as a result of several factors, including state taxes, domestic manufacturing deduction, non-deductible stock-based compensation expense, the benefit of state research and development credits and post acquisition adjustments related to the GreenLine acquisition.

As of May 27, 2012, the Company had unrecognized tax benefits of approximately $766,000. Included in the balance of unrecognized tax benefits as of May 27, 2012 is approximately $593,000 of tax benefits that, if recognized, would result in an adjustment to the Company’s effective tax rate. The Company expects its unrecognized tax benefits to change by $8,000 within the next twelve months related to the expiration of tax attributes.

In accordance with accounting guidance, the Company has decided to classify interest and penalties related to uncertain tax positions as a component of its provision for income taxes. The Company has accrued an insignificant amount of interest and penalties relating to the income tax on the unrecognized tax benefits as of November 25, 2012 and May 27, 2012.

Due to tax attribute carry forwards, the Company is subject to examination for tax years 1996 and later for U.S. tax purposes. The Company was also subject to examination in various state jurisdictions for tax years 1998 and later, none of which were individually significant.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Long-term portion	$	37,192		$	40,305

In addition to entering into the GE Capital real estate and equipment loans mentioned above, on April 23, 2012 in connection with the acquisition of GreenLine, Apio also entered into a five-year, $25.0 million asset-based working capital revolving line of credit with GE Capital, with an interest rate of LIBOR plus 2%, with monthly availability based on the combination of the eligible accounts receivable and eligible inventory. Apio’s revolving line of credit has an unused fee of 0.375% per annum. At November 25, 2012 and May 27, 2012, Apio had $7.5 million and $11.7 million, respectively, outstanding under its revolving line of credit.

Apio’s obligations under the GE Capital real estate, equipment and line of credit agreements (collectively the “GE Debt Agreements”) are secured by liens on all of the property of Apio and its subsidiaries. The GE Debt Agreements contain customary events of default under which obligations could be accelerated or increased. The GE Capital real estate and equipment loans are guaranteed by Landec and Landec has pledged its equity interest in Apio as collateral under the line of credit agreement. The GE Debt Agreements contain customary covenants, such as limitations on the ability to (1) incur indebtedness or grant liens or negative pledges on Apio’s assets; (2) make loans or other investments; (3) pay dividends, sell stock or repurchase stock or other securities; (4) sell assets; (5) engage in mergers; (6) enter into sale and leaseback transactions; and (7) make changes in Apio’s corporate structure. In addition, Apio must maintain a minimum fixed charge coverage ratio of 1.10 to 1.0. Apio was in compliance with all financial covenants as of November 25, 2012. Unamortized loan origination fees for the GE Debt Agreements were $1.1 million and $1.3 million at November 25, 2012 and May 27, 2012, respectively, and are included in other assets in the Consolidated Balance Sheets.

On May 23, 2012, Lifecore entered into two financing agreements with BMO Harris Bank N.A. and/or its affiliates (“BMO Harris”), collectively (the “Lifecore Loan Agreements”):

A Credit and Security Agreement (the “Credit Agreement”) which includes (a) a one-year, $8.0 million asset-based working capital revolving line of credit, with an interest rate of LIBOR plus 1.85%, with availability based on the combination of Lifecore’s eligible accounts receivable and inventory balances (availability was $7.3 million at November 25, 2012) and with no unused fee (at November 25, 2012 and May 27, 2012, no amounts were outstanding under the line of credit) and (b) a $12.0 million term loan which matures in four years due in monthly payments of $250,000 with interest payable monthly based on a variable interest rate of LIBOR plus 2% (the “Term Loan”).

A Reimbursement Agreement pursuant to which BMO Harris caused its affiliate, Bank of Montreal, to issue an irrevocable letter of credit in the amount of $3.5 million (the “Letter of Credit”) which is securing the IRBs described below.

Lifecore’s obligations under the Lifecore Loan Agreements are secured by liens on all of the property of Lifecore. The Lifecore Loan Agreements contain customary covenants, such as limitations on the ability to (1) incur indebtedness or grant liens or negative pledges on Lifecore’s assets; (2) make loans or other investments; (3) pay dividends or repurchase stock or other securities; (4) sell assets; (5) engage in mergers; (6) enter into sale and leaseback transactions; (7) adopt certain benefit plans; and (8) make changes in Lifecore’s corporate structure. In addition, under the Credit Agreement, Lifecore must maintain (a) a minimum fixed charge coverage ratio of 1.10 to 1.0 and a minimum quick ratio of 1.25 to 1.00, both of which must be satisfied as of the end of each fiscal quarter and (b) a minimum tangible net worth of $29,000,000, measured as of May 26, 2013, and as of the end of each fiscal year thereafter. Lifecore was in compliance with all financial covenants as of November 25, 2012. Unamortized loan origination fees for the Lifecore Loan Agreements were $174,000 and $139,000 as of November 25, 2012 and May 27, 2012, respectively, and are included in other assets in the Consolidated Balance Sheets.

The Term Loan was used to repay Lifecore’s former credit facility with Wells Fargo Bank, N.A. (“Wells Fargo”). The Letter of Credit (which replaces a letter of credit previously provided by Wells Fargo) provides liquidity and credit support for the IRBs.

On August 19, 2004, Lifecore issued IRBs. These IRBs were assumed by Landec in the acquisition of Lifecore. The IRBs are collateralized by a bank letter of credit which is secured by a first mortgage on the Company’s facility in Chaska, Minnesota. In addition, the Company pays an annual remarketing fee equal to 0.125% and an annual letter of credit fee of 0.75%. The maturities on the IRBs are held in a sinking fund account, recorded in Other Current Assets in the accompanying Consolidated Balance Sheets, and are paid out each year on September 1st.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Derivative Instruments and Hedging Activities Disclosure [Text Block]

11. Derivative Financial Instruments

In May 2010, the Company entered into a five-year interest rate swap agreement which expires on April 30, 2015, under its prior credit agreement with Wells Fargo. The interest rate swap was designated as a cash flow hedge of future interest payments of LIBOR and had a notional amount of $20 million. As a result of the interest rate swap transaction, the Company fixed for a five-year period the interest rate at 4.24% subject to market based interest rate risk on $20 million of borrowings under the prior credit agreement with Wells Fargo. The Company’s obligations under the interest rate swap transaction as to the scheduled payments were guaranteed and secured on the same basis as its obligations under the credit agreement with Wells Fargo at the time the agreement was consummated. As mentioned in Note 10, upon entering into the new Term Loan with BMO Harris, the Company used the proceeds from that loan to pay off the Wells Fargo credit facility. The swap with Wells Fargo was not terminated upon the extinguishment of the debt with Wells Fargo. As a result of extinguishing the debt with Wells Fargo as of May 23, 2012, the swap was no longer an effective hedge and therefore, the fair value of the swap at the time the debt was extinguished of $347,000 was reversed from other comprehensive income and recorded in other expense during fiscal year 2012. The fair value of the swap arrangement as of November 25, 2012 and May 27, 2012 was $248,000 and $347,000, respectively, and is included in other non-current liabilities in the accompanying balance sheet. The change in the fair value of the swap of $57,000 and $99,000 for the three and six months ended November 25, 2012 is recorded in other income in the accompanying income statement.

13. Stockholders’ Equity

During the three and six months ended November 25, 2012, the Company granted options to purchase 20,000 shares of common stock and 6,666 of restricted stock unit awards.

As of November 25, 2012 the Company has reserved 2.6 million shares of Common Stock for future issuance under its current and former equity plans.

On July 14, 2010, the Company announced that the Board of Directors of the Company had approved the establishment of a stock repurchase plan which allows for the repurchase of up to $10 million of the Company’s Common Stock. The Company may repurchase its common stock from time to time in open market purchases or in privately negotiated transactions. The timing and actual number of shares repurchased is at the discretion of management of the Company and will depend on a variety of factors, including stock price, corporate and regulatory requirements, market conditions, the relative attractiveness of other capital deployment opportunities and other corporate priorities. The stock repurchase program does not obligate Landec to acquire any amount of its common stock and the program may be modified, suspended or terminated at any time at the Company's discretion without prior notice. During both the three and six months ended November 25, 2012, the Company did not purchase any shares on the open market.

Note 14 - Business Segment Reporting

6 Months Ended

Segment Reporting Disclosure [Text Block]

14. Business Segment Reporting

The Company manages its business operations through three strategic business units. Based upon the information reported to the chief operating decision maker, who is the Chief Executive Officer, the Company has the following reportable segments: the Food Products Technology segment, the Food Export segment and the Hyaluronan-based Biomaterials segment.

The Food Products Technology segment markets and packs specialty packaged whole and fresh-cut vegetables that incorporate the BreatheWay specialty packaging for the retail grocery, club store and food services industry. In addition, the Food Products Technology segment sells BreatheWay packaging to partners for non-vegetable products. The Food Export segment consists of revenues generated from the purchase and sale of primarily whole commodity fruit and vegetable products to Asia and domestically. The HA-based Biomaterials segment sells products utilizing hyaluronan, a naturally occurring polysaccharide that is widely distributed in the extracellular matrix of connective tissues in both animals and humans, for medical use primarily in the Ophthalmic, Orthopedic and Veterinary markets. As a result of the sale of Landec Ag to INCOTEC and the termination of the Monsanto Agreement in fiscal year 2012, the Company has eliminated the Technology Licensing segment and combined the remainder of that business into the Corporate segment. As a result of this change, the segment information for the three and six months ended November 27, 2011 has been reclassified to conform with the current year classification. Corporate licenses Landec’s patented Intellicoat seed coatings to the farming industry and licenses the Company’s Intelimer polymers for personal care products and other industrial products. Corporate also includes general and administrative expenses, non Food Products Technology and non HA-based Biomaterials interest income and Company-wide income tax expenses. Beginning in fiscal year 2013, the Food Products Technology, the Food Export and the Hyaluronan-based Biomaterials segments include charges for corporate services and tax sharing allocated from the Corporate segment. All of the assets of the Company are located within the United States of America. The Company’s international sales were as follows (in millions):

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value Measurements

The accounting guidance established a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows:

Level 1 –

observable inputs such as quoted prices for identical instruments in active markets.

Level 2 –

inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data.

Level 3 –

unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.

The fair value of the Company’s interest rate swap is determined based on model inputs that can be observed in a liquid market, including yield curves, and is categorized as Level 2 inputs.
