Accounting Policies [Abstract]
Business	Business Calavo Growers, Inc. (Calavo, the Company, we, us or our), is a global leader in the avocado industry and an expanding provider of value-added fresh food. Our expertise in marketing and distributing avocados, prepared avocados, and other perishable foods allows us to deliver a wide array of fresh and prepared food products to retail grocery, foodservice, club stores, mass merchandisers, food distributors and wholesalers on a worldwide basis. We procure avocados principally from California and Mexico. Through our various operating facilities, we (i) sort, pack, and/or ripen avocados, tomatoes and Hawaiian grown papayas, (ii) process and package fresh cut fruit and vegetables, salads, wraps, sandwiches, fresh snacking products and a variety of prepared deli items and (iii) produce and package guacamole and salsa. The accompanying unaudited consolidated condensed financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, the accompanying unaudited consolidated condensed financial statements contain all adjustments, consisting of adjustments of a normal recurring nature necessary to present fairly the Company’s financial position, results of operations and cash flows. The results of operations for interim periods are not necessarily indicative of the results that may be expected for a full year. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended October 31, 2016.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In March 2016, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update ("ASU"), Improvements to Employee Share-Based Payment Accounting, which simplified several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The new standard requires excess tax benefits or deficiencies for share-based payments to be recognized as income tax benefit or expense, rather than within additional paid-in capital, when the awards vest or are settled. Furthermore, cash flows related to excess tax benefits are required to be classified as operating activities in the statement of cash flows rather than financing activities. We have elected to account for forfeitures of stock-based awards as they occur. The Company’s early adoption of the amendments resulted in an income tax benefit of approximately $0.3 million on the Company’s net earnings in the first quarter of fiscal year 2017. In July 2015, the FASB issued an ASU for measuring inventory. The core principal of the guidance is that an entity should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this new standard beginning in the three months ended January 31, 2017. The adoption of the amendment did not have a material impact on the Company’s consolidated financial statements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2017, the FASB issued an ASU, Stock Compensation (Topic 718), Scope of Modification Accounting. This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance clarifies that modification accounting will be applied if the value, vesting conditions or classification of the award changes. This ASU will be effective for us beginning the first day of our 2018 fiscal year. We do not anticipate a significant impact on our financial condition, results of operations and cash flows upon adoption. In March 2017, the FASB issued an ASU, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that the service cost component of net periodic benefit costs from defined benefit and other postretirement benefit plans be included in the same Statement of Earnings captions as other compensation costs arising from services rendered by the covered employees during the period. The other components of net benefit cost will be presented in the Statement of Earnings separately from service costs. Following adoption, only service costs will be eligible for capitalization into manufactured inventories, which should reduce diversity in practice. This ASU will be effective for us beginning the first day of our 2019 fiscal year. We do not anticipate a significant impact on our financial condition, results of operations and cash flows upon adoption. In January 2017, the FASB issued an ASU, Business Combinations: Clarifying the Definition of a Business, which adds guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU will be effective for us beginning the first day of our 2019 fiscal year. Early adoption is permitted. We do not expect this ASU to have an impact until an applicable transaction takes place. In October 2016, the FASB issued an ASU, Intra-Entity Transfers of Assets Other Than Inventory, which will require companies to recognize the income tax effects of intra-entity sales and transfers of assets other than inventory, particularly those asset transfers involving intellectual property, in the period in which the transfer occurs. The ASU will be effective for us beginning the first day of our 2019 fiscal year and is not expected to have a significant impact upon adoption. In January 2017, the FASB issued an ASU, Simplifying the Test for Goodwill Impairment, which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. The ASU permits an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This ASU will be effective for us beginning the first day of our 2021 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In February 2016, the FASB issued an ASU, Leases, which requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. The guidance also requires qualitative and specific quantitative disclosures to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities, including significant judgments and changes in judgments. This ASU will be effective for us beginning the first day of our 2020 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In January 2016, the FASB issued an ASU, which requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The guidance is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, result of operations and cash flows. In May 2014, the FASB amended the existing accounting standards for revenue recognition. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We are required to adopt the amendments in the first quarter of fiscal 2019. Early adoption is not permitted. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are evaluating the impact of the adoption of this amended accounting standard on our financial condition, result of operations and cash flows.
