Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | 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 February 23, 2014 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 26, 2013. The results of operations for the nine months ended February 23, 2014 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.
Consolidation, Policy [Policy Text Block] | 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 Corporation 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 its partnership interest in Apio Cooling and its equity investments in non-public companies are not VIEs.
Use of Estimates, Policy [Policy Text Block] | 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; the self-insurance liability; 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 and Cash Equivalents, Policy [Policy Text Block] | 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, Policy [Policy Text Block] | Marketable Securities Short-term marketable securities consist of CDs that are FDIC insured and single A or better rated corporate and municipal bonds with original maturities of more than three months at the date of purchase regardless of the maturity date. 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 February 23, 2014 and May 26, 2013 was zero and $701,000, respectively. The contractual maturities of the Company’s marketable securities that are due in less than one year represented zero and $1.3 million of its marketable securities as of February 23, 2014 and May 26, 2013, respectively. The contractual maturities of the Company’s marketable securities that are due in one to two years represented zero and $251,000 of its marketable securities as of February 23, 2014 and May 26, 2013, respectively. Investments in marketable securities are carried at fair market value with unrealized gains and losses reported as other income. 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. During the three and nine months ended February 23, 2014 and February 24, 2013, the Company did not sell any marketable securities. The cost of securities sold is based on the specific identification method.
Financial Instruments Policy [Policy Text Block] | Financial Instruments The Company’s financial instruments are primarily composed of marketable securities, commercial-term trade payables, grower advances, notes receivable 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 February 23, 2014 and May 26, 2013.
Investment In Non-Public Companies [Policy Text Block] | Investments in Non-Public Companies The Company’s investment in Aesthetic Sciences Corporation (“Aesthetic Sciences”), which is reported as an investment in non-public company, non-fair value, in the accompanying Consolidated Balance Sheets, 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 February 23, 2014 and May 26, 2013. The Company has elected to account for its investment in Windset under the fair value option (see Note 4).
Goodwill and Intangible Assets, Policy [Policy Text Block] | Intangible Assets The Company’s intangible assets are comprised of customer relationships with a finite estimated useful life of twelve to thirteen years and trademarks, 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, in accordance with accounting guidance. For non-goodwill indefinite-lived intangible assets, the Company performs a qualitative analysis in accordance with ASC 350-30-35. For goodwill, the Company performs a quantitative analysis in accordance with ASC 350-20-35. During the fiscal quarter ended February 23, 2014, the Company voluntarily changed the date of its annual goodwill and indefinite-lived intangible assets impairment testing from the last day of the fiscal month in July to the first day of the fiscal fourth quarter. This voluntary change is preferable under the circumstances as it provides the Company with additional time to complete its annual goodwill and indefinite-lived intangible asset impairment testing in advance of its year-end reporting and results in better alignment with the Company’s strategic planning and forecasting process. The voluntary change in accounting principle related to the annual testing date will not delay, accelerate, or avoid an impairment charge. This change is not applied retrospectively as it is impracticable to do so because retrospective application would require application of significant estimates and assumptions with the use of hindsight. Accordingly, the change will be applied prospectively.
Self Insurance Reserve [Policy Text Block] | Partial Self-Insurance on Employee Health Plan The Company provides health insurance benefits to eligible employees under a self-insured plan whereby the Company pays actual medical claims subject to certain stop loss limits. The Company records self-insurance liabilities based on actual claims filed and an estimate of those claims incurred but not reported. Any projection of losses concerning the Company's liability is subject to a high degree of variability. Among the causes of this variability are unpredictable external factors such as inflation rates, changes in severity, benefit level changes, medical costs, and claims settlement patterns. This self-insurance liability is included in accrued liabilities and represents management's best estimate of the amounts that have not been paid as of February 23, 2014. It is reasonably possible that the expense the Company ultimately incurs could differ and adjustments to future reserves may be necessary.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements The Company uses fair value measurement accounting for financial assets and liabilities and for financial instruments and certain other items measured 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 February 23, 2014, the Company held certain assets and liabilities that are required to be measured at fair value on a recurring basis, including marketable securities, interest rate swap and a minority interest investment in Windset. The fair value of the Company’s 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 marketable securities as a Level 1 measurement. 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 a Level 2 measurement. The Company has elected the fair value option of accounting for its investment in Windset. The calculation of fair value 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. The change in the fair market value of the Company’s investment in Windset for the three and nine months ended February 23, 2014 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 February 23, 2014 | At May 26, 2013
Annual consolidated revenue growth rates |  | 4% |  | 3% | to | 9%
Annual consolidated expense growth rates | 3% | to | 4% | 3% | to | 8%
Consolidated income tax rate |  | 15% |  |  | 15% |
Consolidated discount rates | 16% | to | 22% | 18% | to | 28%
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 (collectively the “Discount rate”) and then applies an additional discount for lack of marketability 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 February 23, 2014 |
10% increase in annual revenue growth rates |  | $ | 2,900 |
10% increase in annual expense growth rates |  | $ | (2,700 | )
10% increase in income tax rates |  | $ | (100 | )
10% increase in discount rate |  | $ | (1,600 | )
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 February 23, 2014 and May 26, 2013 (in thousands):
|  | Fair Value at February 23, 2014 |  |  | Fair Value at May 26, 2013 |
Assets: |  | Level 1 |  |  | Level 2 |  |  | Level 3 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |

Revenue Recognition, Policy [Policy Text Block] | 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 collectability. The Company records pricing allowances, including discounts based on arrangements with customers, 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 not 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.
New Accounting Pronouncements, Policy [Policy Text Block] | Unrecognized Tax Benefit In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) ("ASU 2013-11"), which provides that a liability related to an unrecognized tax benefit would be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. In situations in which a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the tax law of the jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit will be presented in the financial statements as a liability and will not be combined with deferred tax assets. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. ASU 2013-11 is effective for fiscal years and interim periods beginning after December 15, 2013, with early adoption permitted. The Company early adopted in the first quarter of fiscal year 2014 this standard and such adoption did not have a significant impact on the Company’s financial position or results of operations.
