Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business Alico, Inc. (“Alico”), together with its subsidiaries (collectively, the “Company", "we", "us" or "our”), is a Florida agribusiness and land management company owning approximately 122,000 acres of land throughout Florida, including approximately 90,000 acres of mineral rights. The Company manages its land based upon its primary usage, and reviews its performance based upon two primary classifications - Alico Citrus and Conservation and Environmental Resources . Financial results are presented based upon its three business segments ( Alico Citrus , Conservation and Environmental Resources and Other Operations). Basis of Presentation The Company has prepared the accompanying financial statements on a consolidated basis. These accompanying Consolidated Financial Statements, which are referred to herein as the “Financial Statements”, have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying Financial Statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the Company’s results as of and for the fiscal years ended September 30, 2017 and 2016 . All significant intercompany transactions and account balances between the consolidated businesses have been eliminated. Segments Operating segments are defined in the criteria established under the Financial Accounting Standards Board - Accounting Standards Codification (“FASB ASC”) Topic 280 as components of public entities that engage in business activities from which they may earn revenues and incur expenses for which separate financial information is available and which is evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to assess performance and allocate resources. The Company’s CODM assesses performance and allocates resources based on three operating segments: Alico Citrus (formerly Orange Co.), Conservation and Environmental Resources and Other Operations. Principles of Consolidation The Financial Statements include the accounts of Alico, Inc. and the accounts of all the subsidiaries in which a controlling interest is held by the Company. Under U.S. GAAP, consolidation is generally required for investments of more than 50% of the outstanding voting stock of an investee, except when control is not held by the majority owner. The Company’s subsidiaries include: Alico Land Development, Inc., Alico-Agri, Ltd., Alico Plant World, LLC, Alico Fruit Company, LLC, Alico Citrus Nursery, LLC, Alico Chemical Sales, LLC, 734 Citrus Holdings LLC and subsidiaries, Alico Fresh Fruit LLC, Alico Skink Mitigation, LLC and Citree Holdings 1, LLC. The Company considers the criteria established under FASB ASC Topic 810, “Consolidations” in its consolidation process. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities as of the date of the accompanying Financial Statements, the disclosure of contingent assets and liabilities in the Financial Statements and the accompanying Notes, and the reported amounts of revenues and expenses and cash flows during the periods presented. Actual results could differ from those estimates based upon future events. The Company evaluates estimates on an ongoing basis. The estimates are based on current and expected economic conditions, historical experience, the experience and judgment of the Company’s management and various other specific assumptions that the Company believes to be reasonable. The Company evaluates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in the Company’s evaluations. Noncontrolling Interest in Consolidated Affiliate The Financial Statements include all assets and liabilities of the less-than- 100% -owned affiliate the Company controls, Citree Holdings I, LLC (“Citree”). Accordingly, the Company has recorded a noncontrolling interest in the equity of such entity. Citree had net losses of $91,432 , $69,230 and $64,014 for the fiscal years ended September 30, 2017 , 2016 , and 2015 , respectively, of which $46,630 , $35,307 and $32,647 was attributable to the Company for fiscal years ended September 30, 2017 , 2016 , and 2015 , respectively. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standard Update ("ASU") 2014-09, “Revenue from Contracts with Customers,” as a new ASC topic (Topic 606). The core principle of this ASU is that an entity should recognize revenue 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. The ASU further provides guidance for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (for example, lease contracts). The FASB subsequently issued ASU 2015-14 to defer the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with earlier adoption permitted. The FASB also recently issued ASU 2016-10, "Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing," and 2016-12, "Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients," that clarify or amend the original Topic 606. ASU 2014-09 can be adopted using one of two retrospective transition methods: 1) retrospectively to each prior reporting period presented or 2) as a cumulative-effect adjustment as of the date of adoption. The Company has not yet selected a transition method and is currently evaluating the impact of ASU 2014-09 on the Company’s Financial Statements upon adoption. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)." This guidance will require entities that enter into leases as a lessee to recognize right-of-use assets and lease liabilities for those leases classified as operating leases under previous GAAP. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. The Company is currently evaluating the impact this guidance will have on our Financial Statements, and it will become effective for Alico at the beginning of its first quarter of fiscal 2020. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." The amendment clarifies the implementation guidance for principal versus agent considerations as contained in ASU No. 2014-09, Revenue from Contracts with Customers. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to a customer. ASU No. 2016-08 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption of ASU No. 2016-08 is permitted but not before December 15, 2016. The Company is currently evaluating the impact of ASU No. 2016-08 on our Financial Statements. In March 2016, the FASB issued ASU 2016-09, “Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The objective of this update is to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. This guidance, which will be adopted October 1, 2017, is not expected to have a significant impact on our Financial Statements In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” This ASU will provide guidance on the presentation and classification of specific cash flow items to improve consistency within the statement of cash flows. The effective date for adoption of this guidance would be our fiscal year beginning October 1, 2018, with early adoption permitted. The Company is currently evaluating the effect that ASU 2016-15 will have on our Financial Statements. In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” (ASC Topic 740, Income Taxes), which will require an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This ASU is effective for the Company on October 1, 2018 with early adoption permitted. The Company has not yet evaluated the effect, if any, that ASU 2016-16 will have on our Financial Statements. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" that provides guidance to assist entities with evaluating when a set of transferred assets and activities (set) is a business. Under the new guidance, an entity first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. The ASU will be applied prospectively to any transactions occurring within the period of adoption. Early adoption is permitted. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other” (Topic 350) which simplifies the accounting for goodwill impairment. The updated guidance eliminates Step 2 of the impairment test, which requires entities to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value, determined in Step 1. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. We will adopt this guidance using a prospective approach. Earlier adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" (Subtopic 610-20): The ASU clarifies that ASC 610-20 applies to the derecognition of nonfinancial assets and in substance nonfinancial assets unless other specific guidance applies. As a result, it will not apply to the derecognition of businesses, nonprofit activities, or financial assets (including equity method investments), or to contracts with customers. The ASU also clarifies that an in substance nonfinancial asset is an asset or group of assets for which substantially all of the fair value consists of nonfinancial assets and the group or subsidiary is not a business. In addition, transfers of nonfinancial assets to another entity in exchange for a noncontrolling ownership interest in that entity will be accounted for under ASC 610-20, removing specific guidance on such partial exchanges from ASC 845, Nonmonetary Transactions . As a result, guidance specific to real estate sales in ASC 360-20 will be eliminated. As such, sales and partial sales of real estate assets will now be subject to the same derecognition model as all other nonfinancial assets. The ASU will also impact the accounting for partial sales of nonfinancial assets (including in substance real estate). When an entity transfers its controlling interest in a nonfinancial asset, but retains a noncontrolling ownership interest, the entity will measure the retained interest at fair value. This will result in full gain/loss recognition upon the sale of a controlling interest in a nonfinancial asset. Current guidance generally prohibits gain recognition on the retained interest. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years and early adoption is permitted. The ASU will be applied prospectively to any transaction occurring from the date of adoption. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation” (Topic 718) which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. We do not expect this new guidance to have a material impact on our consolidated financial statements. The Company has reviewed other recently issued accounting standards which have not yet been adopted in order to determine their potential effect, if any, on the results of operations or financial condition. Based on the review of these other recently issued standards, the Company does not currently believe that any of those accounting pronouncements will have a significant effect on its current or future financial position, results of operations, cash flows or disclosures. Reclassifications Certain prior year amounts have been reclassified in the accompanying Financial Statements for consistent presentation to the current period. These reclassifications had no impact on net income, equity or cash flows as previously reported; however, working capital decreased by approximately $1,184,000 at September 30, 2016 . Seasonality The Company is primarily engaged in the production of fruit for sale to citrus markets, which is of a seasonal nature, and subject to the influence of natural phenomena and wide price fluctuations. Historically, the second and third quarters of our fiscal year generally produce the majority of our annual revenue, and working capital requirements are typically greater in the first and fourth quarters of the fiscal year. The results of the reported periods herein are not necessarily indicative of the results for any other interim periods or the entire fiscal year. Summary of Significant Accounting Policies Business Combinations The Company accounts for its business acquisitions under the acquisition method of accounting as indicated in FASB ASC 805, “Business Combinations”, which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed and any noncontrolling interest in the acquiree, and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities and noncontrolling interest in the acquiree, based on fair value estimates as of the date of acquisition. In accordance with FASB ASC 805, the Company recognizes and measures goodwill, if any, as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. When we acquire a business from an entity under common control, whereby the companies are ultimately controlled by the same party or parties both before and after the transaction, it is treated similar to the pooling of interests method of accounting. The assets and liabilities are recorded at the transferring entity’s historical cost instead of reflecting the fair value of assets and liabilities. Revenue Recognition Revenues from agricultural crops are recognized at the time the crop is harvested and delivered to the customer. Receivables from crops sold are recorded for the estimated proceeds to be received from the customer. On a quarterly basis, management reviews the reasonableness of the revenues accrued based on buyers’ and processors’ advances to growers, cash and futures markets and experience in the industry. Adjustments are made throughout the year to these estimates as more current relevant industry information becomes available. Differences between the estimates and the final realization of revenues can be significant and can be either an increase or decrease to reported revenues. During the periods presented in this report, no material adjustments were made to the reported revenues of the Company’s crops. Alico recognizes revenues from cattle sales at the time the cattle are delivered. Alico Fruit Company, LLC ("AFC") operations primarily consist of providing supply chain management services to Alico, as well as to other citrus growers and processors in the state of Florida. AFC also purchases and resells citrus fruit; in these transactions, AFC (i) acts as a principal; (ii) takes title to the products; and (iii) has the risks and rewards of ownership, including the risk of loss for collection, delivery or returns. Therefore, AFC recognizes revenues based on the gross amounts due from customers for its marketing activities. Supply chain management services revenues are recognized when the services are performed. Fair Value of Financial Instruments The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short term and immediate nature of these financial instruments. The carrying amounts of our debt approximates fair value as the debt is with commercial lenders at interest rates that vary with market conditions or have fixed rates that approximate market rates for obligations with similar terms and maturities (see Note 10. “Fair Value Measurements”). Cash and Cash Equivalents The Company considers cash in banks and highly liquid instruments with an original maturity of three months or less to be cash and cash equivalents. At various times throughout the fiscal year, and as of September 30, 2017 , some accounts held at financial institutions were in excess of the federally insured limit of $250,000. The Company has not experienced any losses on these accounts and believes credit risk to be minimal. Accounts receivable Accounts receivable from customers are generated from revenues based on the sale of citrus, cattle, leasing and other transactions. The Company grants credit in the course of its operations to third party customers. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. The Company provides an allowance for doubtful accounts for amounts which are not probable of collection. The estimate, evaluated quarterly by the Company, is based on historical collection experience, current macroeconomic climate and market conditions and a review of the current status each customer’s account. Changes in the financial viability of significant customers and worsening of economic conditions may require changes to its estimate of the recoverability of the receivables. Such changes in estimates are recorded in the period in which these changes become known. The allowance for doubtful accounts is included in general and administrative expenses in the Consolidated Statements of Operations. The following table presents accounts receivable, net for fiscal years ended September 30, 2017 and 2016 : (in thousands) September 30, 2017 2016 Accounts receivable $ 4,314 $ 4,753 Allowance for doubtful accounts (28 ) (13 ) Accounts receivable, net $ 4,286 $ 4,740 Concentrations Accounts receivable from the Company’s major customers as of September 30, 2017 and 2016 and revenue for the fiscal years ended September 30, 2017 , 2016 and 2015 , are as follows: (in thousands) Accounts Receivable Revenue % of Total Revenue 2017 2016 2017 2016 2015 2017 2016 2015 Tropicana $ 2,506 $ 1,710 $ 111,197 $ 46,898 $ 21,925 85.6 % 32.5 % 14.3 % Cutrale Citrus Juice $ — $ — $ 1,364 $ 22,735 $ 23,556 1.1 % 15.8 % 15.4 % Minute Maid $ — $ — $ — $ 49,271 $ 57,484 — % 34.2 % 37.5 % Louis Dreyfus $ — $ — $ — $ — $ 22,460 — % — % 14.7 % The citrus industry is subject to various factors over which growers have limited or no control, including weather conditions, disease, pestilence, water supply and market price fluctuations. Market prices are highly sensitive to aggregate domestic and foreign crop sizes, as well as factors including, but not limited to, weather and competition from foreign countries. Real Estate In recognizing revenues from land sales, the Company applies specific revenue recognition criteria, in accordance with U.S. GAAP, to determine when land sales revenues can be recorded. For example, in order to fully recognize a gain resulting from a real estate transaction, the sale must be consummated with a sufficient down payment of at least 20% to 25% of the sales price depending upon the type and timeframe for development of the property sold and any receivable from the sale cannot be subject to future subordination. In addition, the seller cannot retain any material continuing involvement in the property sold. When these criteria are not met, the Company recognizes a gain proportionate to collections utilizing either the installment method or deposit method as appropriate. Inventories The costs of growing crops, including but not limited to labor, fertilization, fuel, crop nutrition and irrigation, are capitalized into inventory throughout the respective crop year. Such costs are expensed as cost of sales when the crops are harvested and are recorded as operating expenses in the Consolidated Statements of Operations. Inventories are stated at the lower of cost or net realizable value. The cost for unharvested citrus crops is based on accumulated production costs incurred during the period from January 1 through the balance sheet date. The cost of the beef cattle inventory is based on the accumulated cost of developing such animals for sale from July 1 through the balance sheet date (see Note 5. “Inventories”). Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation, depletion and amortization. Major improvements are capitalized while expenditures for maintenance and repairs are expensed when incurred. Costs related to the development of citrus groves through planting of trees are capitalized. Such costs include land clearing, excavation and construction of ditches, dikes, roads, and reservoirs, among other costs. After the planting, caretaking costs or pre-productive maintenance costs are capitalized for four years. After four years, a planting is considered to have reached maturity and the accumulated costs are depreciated over 25 years, except for land clearing and excavation, which are considered costs of land and not depreciated. The breeding herd consists of purchased animals and animals raised on the Company’s ranches. Purchased animals are stated at the cost of acquisition. The cost of animals raised on the ranch is based on the accumulated cost of developing such animals for productive use. Real estate costs incurred for the acquisition, development and construction of real estate projects are capitalized. Depreciation is provided on a straight-line basis over the estimated useful lives of the depreciable assets, with the exception of leasehold improvements and assets acquired through capital leases, which are depreciated over their estimated useful lives if the lease transfers ownership or contains a bargain purchase option, otherwise the term of the lease. The estimated useful lives for property and equipment are primarily as follows: Citrus trees 25 years Equipment and other facilities 3-20 years Buildings and improvements 25-39 years Breeding herd 5-7 years Changes in circumstances, such as technological advances or changes to our business model or capital strategy could result in the actual useful lives differing from the original estimates. In those cases where we determine that the useful life of property and equipment should be shortened, we would depreciate the asset over its revised estimated remaining useful life, thereby increasing depreciation expense (see Note 7. “Property and Equipment, Net”). Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. The Company records impairment losses on long-lived assets used in operations, or asset group, when events and circumstances indicate that the assets might be impaired and the estimated cash flows (undiscounted and without interest charges) to be generated by those assets or asset group over the remaining lives of the assets or asset group are less than the carrying amounts of those assets. In calculating impairments and the estimated cash flows, the Company assigns its asset groups by determining the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of the other Company assets. The net carrying values of assets or asset group not recoverable are reduced to their fair values. Our cash flow estimates are based on historical results adjusted to reflect our best estimates of future market conditions and operating conditions. As of September 30, 2017 and 2016 , long-lived assets were comprised of property and equipment. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price of acquired businesses over the fair value of the assets acquired less liabilities assumed in connection with such acquisition. In accordance with the provisions of ASC 350, Intangibles-Goodwill and Other, goodwill and intangible assets with indefinite useful lives acquired in an acquisition are not amortized, but instead are tested for impairment at least annually, on the same date, or more frequently should an event occur or circumstances indicate that the carrying amount may be impaired. Such events or circumstances may be a significant change in business climate, economic and industry trends, legal factors, negative operating performance indicators, significant competition, changes in strategy or disposition of a reporting unit or a portion thereof. In the evaluation of goodwill for impairment, we have the option to perform a qualitative assessment to determine whether further impairment testing is necessary or to perform a quantitative assessment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Under the qualitative assessment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. If, under the quantitative assessment, the fair value of a reporting unit is less than its carrying amount, then the amount of the impairment loss, if any, must be measured under step two of the impairment analysis. In step two of the analysis, we would record an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, should such a circumstance arise. As of September 30, 2017 and 2016, no impairment was required. Other Non-Current Assets Other non-current assets primarily include investments owned in agricultural cooperatives, cash surrender value on life insurance and equity investment in affiliate (Magnolia). Investments in stock related to agricultural cooperatives are carried at cost. Income Taxes The Company uses the asset and liability method of accounting for deferred income taxes. The provision for income taxes includes income taxes currently payable and those deferred as a result of temporary differences between the financial statements and the income tax basis of assets and liabilities. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income or loss in the period that includes the enactment date. A valuation allowance is provided to reduce deferred tax assets to the amount of future tax benefit when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Projected future taxable income and ongoing tax planning strategies are considered and evaluated when assessing the need for a valuation allowance. Any increase or decrease in a valuation allowance could have a material adverse or beneficial impact on the Company’s income tax provision and net income or loss in the period the determination is made. As of September 30, 2017 and 2016 , the Company did not record a valuation allowance on deferred tax assets. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. The Company records interest related to unrecognized tax benefits in income tax expense. Earnings per Share Basic earnings per share for our common stock is calculated by dividing net income attributable to Alico common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per common share is similarly calculated, except that the calculation includes the dilutive effect of the assumed issuance of shares of common stock issuable under equity-based compensation plans in accordance with the treasury stock method, or any other type of securities convertible into common stock, except where the inclusion of such common shares would have an anti-dilutive effect. The following table presents a reconciliation of basic to diluted weighted average common shares outstanding for fiscal years ended September 30, 2017 , 2016 and 2015 : (in thousands) Fiscal Year Ended September 30, 2017 2016 2015 Weighted Average Common Shares Outstanding - Basic 8,300 8,303 8,056 Effect of dilutive securities - stock options and unrestricted stock — 8 5 Weighted Average Common Shares Outstanding - Diluted 8,300 8,311 8,061 For the fiscal year ended September 30, 2017 , the Company issued 750,000 stock options to certain executives of the Company. There were no employee stock options granted for the fiscal years ended September 30, 2016 and 2015 , respectively. Non-vested restricted shares of common stock entitle the holder to receive non-forfeitable dividends upon issuance and are included in the calculation of diluted earnings per common share. For the fiscal year ended September 30, 2017 , the Company had stock options that were excluded from the diluted earnings per share because they were anti-dilutive. For the fiscal years ended September 30, 2016 and 2015 , there were no anti-dilutive equity awards or convertible securities that were excluded from the calculation of diluted earnings per common share. Stock-Based Compensation Stock-based compensation is measured based on the fair value of the equity award at the grant date and is typically expensed on a straight-line basis over the vesting period. Upon the vesting of restricted stock, the Company issues common stock from common shares held in treasury. Total stock-based compensation expense for the three years ended September 30, 2017 in g

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Description of Business and Basis of Presentation Description of Business Alico, Inc. (“Alico”), together with its subsidiaries (collectively, the “Company", "we", "us" or "our”), is a Florida agribusiness and land management company owning approximately 122,000 acres of land throughout Florida, including approximately 90,000 acres of mineral rights. The Company manages its land based upon its primary usage, and reviews its performance based upon two primary classifications - Alico Citrus and Conservation and Environmental Resources . Financial results are presented based upon its three business segments ( Alico Citrus , Conservation and Environmental Resources and Other Operations). Basis of Presentation The Company has prepared the accompanying financial statements on a consolidated basis. These accompanying Consolidated Financial Statements, which are referred to herein as the “Financial Statements”, have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying Financial Statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the Company’s results as of and for the fiscal years ended September 30, 2017 and 2016 . All significant intercompany transactions and account balances between the consolidated businesses have been eliminated. Segments Operating segments are defined in the criteria established under the Financial Accounting Standards Board - Accounting Standards Codification (“FASB ASC”) Topic 280 as components of public entities that engage in business activities from which they may earn revenues and incur expenses for which separate financial information is available and which is evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to assess performance and allocate resources. The Company’s CODM assesses performance and allocates resources based on three operating segments: Alico Citrus (formerly Orange Co.), Conservation and Environmental Resources and Other Operations. Principles of Consolidation The Financial Statements include the accounts of Alico, Inc. and the accounts of all the subsidiaries in which a controlling interest is held by the Company. Under U.S. GAAP, consolidation is generally required for investments of more than 50% of the outstanding voting stock of an investee, except when control is not held by the majority owner. The Company’s subsidiaries include: Alico Land Development, Inc., Alico-Agri, Ltd., Alico Plant World, LLC, Alico Fruit Company, LLC, Alico Citrus Nursery, LLC, Alico Chemical Sales, LLC, 734 Citrus Holdings LLC and subsidiaries, Alico Fresh Fruit LLC, Alico Skink Mitigation, LLC and Citree Holdings 1, LLC. The Company considers the criteria established under FASB ASC Topic 810, “Consolidations” in its consolidation process. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities as of the date of the accompanying Financial Statements, the disclosure of contingent assets and liabilities in the Financial Statements and the accompanying Notes, and the reported amounts of revenues and expenses and cash flows during the periods presented. Actual results could differ from those estimates based upon future events. The Company evaluates estimates on an ongoing basis. The estimates are based on current and expected economic conditions, historical experience, the experience and judgment of the Company’s management and various other specific assumptions that the Company believes to be reasonable. The Company evaluates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in the Company’s evaluations. Noncontrolling Interest in Consolidated Affiliate The Financial Statements include all assets and liabilities of the less-than- 100% -owned affiliate the Company controls, Citree Holdings I, LLC (“Citree”). Accordingly, the Company has recorded a noncontrolling interest in the equity of such entity. Citree had net losses of $91,432 , $69,230 and $64,014 for the fiscal years ended September 30, 2017 , 2016 , and 2015 , respectively, of which $46,630 , $35,307 and $32,647 was attributable to the Company for fiscal years ended September 30, 2017 , 2016 , and 2015 , respectively. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standard Update ("ASU") 2014-09, “Revenue from Contracts with Customers,” as a new ASC topic (Topic 606). The core principle of this ASU is that an entity should recognize revenue 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. The ASU further provides guidance for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (for example, lease contracts). The FASB subsequently issued ASU 2015-14 to defer the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with earlier adoption permitted. The FASB also recently issued ASU 2016-10, "Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing," and 2016-12, "Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients," that clarify or amend the original Topic 606. ASU 2014-09 can be adopted using one of two retrospective transition methods: 1) retrospectively to each prior reporting period presented or 2) as a cumulative-effect adjustment as of the date of adoption. The Company has not yet selected a transition method and is currently evaluating the impact of ASU 2014-09 on the Company’s Financial Statements upon adoption. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)." This guidance will require entities that enter into leases as a lessee to recognize right-of-use assets and lease liabilities for those leases classified as operating leases under previous GAAP. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. The Company is currently evaluating the impact this guidance will have on our Financial Statements, and it will become effective for Alico at the beginning of its first quarter of fiscal 2020. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." The amendment clarifies the implementation guidance for principal versus agent considerations as contained in ASU No. 2014-09, Revenue from Contracts with Customers. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to a customer. ASU No. 2016-08 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption of ASU No. 2016-08 is permitted but not before December 15, 2016. The Company is currently evaluating the impact of ASU No. 2016-08 on our Financial Statements. In March 2016, the FASB issued ASU 2016-09, “Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The objective of this update is to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. This guidance, which will be adopted October 1, 2017, is not expected to have a significant impact on our Financial Statements In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” This ASU will provide guidance on the presentation and classification of specific cash flow items to improve consistency within the statement of cash flows. The effective date for adoption of this guidance would be our fiscal year beginning October 1, 2018, with early adoption permitted. The Company is currently evaluating the effect that ASU 2016-15 will have on our Financial Statements. In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” (ASC Topic 740, Income Taxes), which will require an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This ASU is effective for the Company on October 1, 2018 with early adoption permitted. The Company has not yet evaluated the effect, if any, that ASU 2016-16 will have on our Financial Statements. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" that provides guidance to assist entities with evaluating when a set of transferred assets and activities (set) is a business. Under the new guidance, an entity first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. The ASU will be applied prospectively to any transactions occurring within the period of adoption. Early adoption is permitted. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other” (Topic 350) which simplifies the accounting for goodwill impairment. The updated guidance eliminates Step 2 of the impairment test, which requires entities to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value, determined in Step 1. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. We will adopt this guidance using a prospective approach. Earlier adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" (Subtopic 610-20): The ASU clarifies that ASC 610-20 applies to the derecognition of nonfinancial assets and in substance nonfinancial assets unless other specific guidance applies. As a result, it will not apply to the derecognition of businesses, nonprofit activities, or financial assets (including equity method investments), or to contracts with customers. The ASU also clarifies that an in substance nonfinancial asset is an asset or group of assets for which substantially all of the fair value consists of nonfinancial assets and the group or subsidiary is not a business. In addition, transfers of nonfinancial assets to another entity in exchange for a noncontrolling ownership interest in that entity will be accounted for under ASC 610-20, removing specific guidance on such partial exchanges from ASC 845, Nonmonetary Transactions . As a result, guidance specific to real estate sales in ASC 360-20 will be eliminated. As such, sales and partial sales of real estate assets will now be subject to the same derecognition model as all other nonfinancial assets. The ASU will also impact the accounting for partial sales of nonfinancial assets (including in substance real estate). When an entity transfers its controlling interest in a nonfinancial asset, but retains a noncontrolling ownership interest, the entity will measure the retained interest at fair value. This will result in full gain/loss recognition upon the sale of a controlling interest in a nonfinancial asset. Current guidance generally prohibits gain recognition on the retained interest. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years and early adoption is permitted. The ASU will be applied prospectively to any transaction occurring from the date of adoption. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation” (Topic 718) which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. We do not expect this new guidance to have a material impact on our consolidated financial statements. The Company has reviewed other recently issued accounting standards which have not yet been adopted in order to determine their potential effect, if any, on the results of operations or financial condition. Based on the review of these other recently issued standards, the Company does not currently believe that any of those accounting pronouncements will have a significant effect on its current or future financial position, results of operations, cash flows or disclosures. Reclassifications Certain prior year amounts have been reclassified in the accompanying Financial Statements for consistent presentation to the current period. These reclassifications had no impact on net income, equity or cash flows as previously reported; however, working capital decreased by approximately $1,184,000 at September 30, 2016 . Seasonality The Company is primarily engaged in the production of fruit for sale to citrus markets, which is of a seasonal nature, and subject to the influence of natural phenomena and wide price fluctuations. Historically, the second and third quarters of our fiscal year generally produce the majority of our annual revenue, and working capital requirements are typically greater in the first and fourth quarters of the fiscal year. The results of the reported periods herein are not necessarily indicative of the results for any other interim periods or the entire fiscal year. Summary of Significant Accounting Policies Business Combinations The Company accounts for its business acquisitions under the acquisition method of accounting as indicated in FASB ASC 805, “Business Combinations”, which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed and any noncontrolling interest in the acquiree, and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities and noncontrolling interest in the acquiree, based on fair value estimates as of the date of acquisition. In accordance with FASB ASC 805, the Company recognizes and measures goodwill, if any, as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. When we acquire a business from an entity under common control, whereby the companies are ultimately controlled by the same party or parties both before and after the transaction, it is treated similar to the pooling of interests method of accounting. The assets and liabilities are recorded at the transferring entity’s historical cost instead of reflecting the fair value of assets and liabilities. Revenue Recognition Revenues from agricultural crops are recognized at the time the crop is harvested and delivered to the customer. Receivables from crops sold are recorded for the estimated proceeds to be received from the customer. On a quarterly basis, management reviews the reasonableness of the revenues accrued based on buyers’ and processors’ advances to growers, cash and futures markets and experience in the industry. Adjustments are made throughout the year to these estimates as more current relevant industry information becomes available. Differences between the estimates and the final realization of revenues can be significant and can be either an increase or decrease to reported revenues. During the periods presented in this report, no material adjustments were made to the reported revenues of the Company’s crops. Alico recognizes revenues from cattle sales at the time the cattle are delivered. Alico Fruit Company, LLC ("AFC") operations primarily consist of providing supply chain management services to Alico, as well as to other citrus growers and processors in the state of Florida. AFC also purchases and resells citrus fruit; in these transactions, AFC (i) acts as a principal; (ii) takes title to the products; and (iii) has the risks and rewards of ownership, including the risk of loss for collection, delivery or returns. Therefore, AFC recognizes revenues based on the gross amounts due from customers for its marketing activities. Supply chain management services revenues are recognized when the services are performed. Fair Value of Financial Instruments The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short term and immediate nature of these financial instruments. The carrying amounts of our debt approximates fair value as the debt is with commercial lenders at interest rates that vary with market conditions or have fixed rates that approximate market rates for obligations with similar terms and maturities (see Note 10. “Fair Value Measurements”). Cash and Cash Equivalents The Company considers cash in banks and highly liquid instruments with an original maturity of three months or less to be cash and cash equivalents. At various times throughout the fiscal year, and as of September 30, 2017 , some accounts held at financial institutions were in excess of the federally insured limit of $250,000. The Company has not experienced any losses on these accounts and believes credit risk to be minimal. Accounts receivable Accounts receivable from customers are generated from revenues based on the sale of citrus, cattle, leasing and other transactions. The Company grants credit in the course of its operations to third party customers. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. The Company provides an allowance for doubtful accounts for amounts which are not probable of collection. The estimate, evaluated quarterly by the Company, is based on historical collection experience, current macroeconomic climate and market conditions and a review of the current status each customer’s account. Changes in the financial viability of significant customers and worsening of economic conditions may require changes to its estimate of the recoverability of the receivables. Such changes in estimates are recorded in the period in which these changes become known. The allowance for doubtful accounts is included in general and administrative expenses in the Consolidated Statements of Operations. The following table presents accounts receivable, net for fiscal years ended September 30, 2017 and 2016 : (in thousands) September 30, 2017 2016 Accounts receivable $ 4,314 $ 4,753 Allowance for doubtful accounts (28 ) (13 ) Accounts receivable, net $ 4,286 $ 4,740 Concentrations Accounts receivable from the Company’s major customers as of September 30, 2017 and 2016 and revenue for the fiscal years ended September 30, 2017 , 2016 and 2015 , are as follows: (in thousands) Accounts Receivable Revenue % of Total Revenue 2017 2016 2017 2016 2015 2017 2016 2015 Tropicana $ 2,506 $ 1,710 $ 111,197 $ 46,898 $ 21,925 85.6 % 32.5 % 14.3 % Cutrale Citrus Juice $ — $ — $ 1,364 $ 22,735 $ 23,556 1.1 % 15.8 % 15.4 % Minute Maid $ — $ — $ — $ 49,271 $ 57,484 — % 34.2 % 37.5 % Louis Dreyfus $ — $ — $ — $ — $ 22,460 — % — % 14.7 % The citrus industry is subject to various factors over which growers have limited or no control, including weather conditions, disease, pestilence, water supply and market price fluctuations. Market prices are highly sensitive to aggregate domestic and foreign crop sizes, as well as factors including, but not limited to, weather and competition from foreign countries. Real Estate In recognizing revenues from land sales, the Company applies specific revenue recognition criteria, in accordance with U.S. GAAP, to determine when land sales revenues can be recorded. For example, in order to fully recognize a gain resulting from a real estate transaction, the sale must be consummated with a sufficient down payment of at least 20% to 25% of the sales price depending upon the type and timeframe for development of the property sold and any receivable from the sale cannot be subject to future subordination. In addition, the seller cannot retain any material continuing involvement in the property sold. When these criteria are not met, the Company recognizes a gain proportionate to collections utilizing either the installment method or deposit method as appropriate. Inventories The costs of growing crops, including but not limited to labor, fertilization, fuel, crop nutrition and irrigation, are capitalized into inventory throughout the respective crop year. Such costs are expensed as cost of sales when the crops are harvested and are recorded as operating expenses in the Consolidated Statements of Operations. Inventories are stated at the lower of cost or net realizable value. The cost for unharvested citrus crops is based on accumulated production costs incurred during the period from January 1 through the balance sheet date. The cost of the beef cattle inventory is based on the accumulated cost of developing such animals for sale from July 1 through the balance sheet date (see Note 5. “Inventories”). Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation, depletion and amortization. Major improvements are capitalized while expenditures for maintenance and repairs are expensed when incurred. Costs related to the development of citrus groves through planting of trees are capitalized. Such costs include land clearing, excavation and construction of ditches, dikes, roads, and reservoirs, among other costs. After the planting, caretaking costs or pre-productive maintenance costs are capitalized for four years. After four years, a planting is considered to have reached maturity and the accumulated costs are depreciated over 25 years, except for land clearing and excavation, which are considered costs of land and not depreciated. The breeding herd consists of purchased animals and animals raised on the Company’s ranches. Purchased animals are stated at the cost of acquisition. The cost of animals raised on the ranch is based on the accumulated cost of developing such animals for productive use. Real estate costs incurred for the acquisition, development and construction of real estate projects are capitalized. Depreciation is provided on a straight-line basis over the estimated useful lives of the depreciable assets, with the exception of leasehold improvements and assets acquired through capital leases, which are depreciated over their estimated useful lives if the lease transfers ownership or contains a bargain purchase option, otherwise the term of the lease. The estimated useful lives for property and equipment are primarily as follows: Citrus trees 25 years Equipment and other facilities 3-20 years Buildings and improvements 25-39 years Breeding herd 5-7 years Changes in circumstances, such as technological advances or changes to our business model or capital strategy could result in the actual useful lives differing from the original estimates. In those cases where we determine that the useful life of property and equipment should be shortened, we would depreciate the asset over its revised estimated remaining useful life, thereby increasing depreciation expense (see Note 7. “Property and Equipment, Net”). Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. The Company records impairment losses on long-lived assets used in operations, or asset group, when events and circumstances indicate that the assets might be impaired and the estimated cash flows (undiscounted and without interest charges) to be generated by those assets or asset group over the remaining lives of the assets or asset group are less than the carrying amounts of those assets. In calculating impairments and the estimated cash flows, the Company assigns its asset groups by determining the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of the other Company assets. The net carrying values of assets or asset group not recoverable are reduced to their fair values. Our cash flow estimates are based on historical results adjusted to reflect our best estimates of future market conditions and operating conditions. As of September 30, 2017 and 2016 , long-lived assets were comprised of property and equipment. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price of acquired businesses over the fair value of the assets acquired less liabilities assumed in connection with such acquisition. In accordance with the provisions of ASC 350, Intangibles-Goodwill and Other, goodwill and intangible assets with indefinite useful lives acquired in an acquisition are not amortized, but instead are tested for impairment at least annually, on the same date, or more frequently should an event occur or circumstances indicate that the carrying amount may be impaired. Such events or circumstances may be a significant change in business climate, economic and industry trends, legal factors, negative operating performance indicators, significant competition, changes in strategy or disposition of a reporting unit or a portion thereof. In the evaluation of goodwill for impairment, we have the option to perform a qualitative assessment to determine whether further impairment testing is necessary or to perform a quantitative assessment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Under the qualitative assessment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. If, under the quantitative assessment, the fair value of a reporting unit is less than its carrying amount, then the amount of the impairment loss, if any, must be measured under step two of the impairment analysis. In step two of the analysis, we would record an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, should such a circumstance arise. As of September 30, 2017 and 2016, no impairment was required. Other Non-Current Assets Other non-current assets primarily include investments owned in agricultural cooperatives, cash surrender value on life insurance and equity investment in affiliate (Magnolia). Investments in stock related to agricultural cooperatives are carried at cost. Income Taxes The Company uses the asset and liability method of accounting for deferred income taxes. The provision for income taxes includes income taxes currently payable and those deferred as a result of temporary differences between the financial statements and the income tax basis of assets and liabilities. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income or loss in the period that includes the enactment date. A valuation allowance is provided to reduce deferred tax assets to the amount of future tax benefit when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Projected future taxable income and ongoing tax planning strategies are considered and evaluated when assessing the need for a valuation allowance. Any increase or decrease in a valuation allowance could have a material adverse or beneficial impact on the Company’s income tax provision and net income or loss in the period the determination is made. As of September 30, 2017 and 2016 , the Company did not record a valuation allowance on deferred tax assets. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. The Company records interest related to unrecognized tax benefits in income tax expense. Earnings per Share Basic earnings per share for our common stock is calculated by dividing net income attributable to Alico common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per common share is similarly calculated, except that the calculation includes the dilutive effect of the assumed issuance of shares of common stock issuable under equity-based compensation plans in accordance with the treasury stock method, or any other type of securities convertible into common stock, except where the inclusion of such common shares would have an anti-dilutive effect. The following table presents a reconciliation of basic to diluted weighted average common shares outstanding for fiscal years ended September 30, 2017 , 2016 and 2015 : (in thousands) Fiscal Year Ended September 30, 2017 2016 2015 Weighted Average Common Shares Outstanding - Basic 8,300 8,303 8,056 Effect of dilutive securities - stock options and unrestricted stock — 8 5 Weighted Average Common Shares Outstanding - Diluted 8,300 8,311 8,061 For the fiscal year ended September 30, 2017 , the Company issued 750,000 stock options to certain executives of the Company. There were no employee stock options granted for the fiscal years ended September 30, 2016 and 2015 , respectively. Non-vested restricted shares of common stock entitle the holder to receive non-forfeitable dividends upon issuance and are included in the calculation of diluted earnings per common share. For the fiscal year ended September 30, 2017 , the Company had stock options that were excluded from the diluted earnings per share because they were anti-dilutive. For the fiscal years ended September 30, 2016 and 2015 , there were no anti-dilutive equity awards or convertible securities that were excluded from the calculation of diluted earnings per common share. Stock-Based Compensation Stock-based compensation is measured based on the fair value of the equity award at the grant date and is typically expensed on a straight-line basis over the vesting period. Upon the vesting of restricted stock, the Company issues common stock from common shares held in treasury. Total stock-based compensation expense for the three years ended September 30, 2017 in g

Acquisitions and Dispositions	Acquisitions and Dispositions Acquisition of Orange-Co, LP Assets On December 2, 2014 , the Company completed the acquisition of certain citrus and related assets of Orange-Co, LP, including 51% of the ownership interests of Citree, pursuant to an Asset Purchase Agreement, which is referred to as the Orange-Co Purchase Agreement, dated as of December 1, 2014 . The assets the Company purchased include approximately 20,263 acres of citrus groves in DeSoto and Charlotte Counties, Florida, which comprise one of the largest contiguous citrus grove properties in the state of Florida. Total assets acquired were approximately $277,792,000 , net of approximately $2,060,000 in cash acquired and approximately $4,838,000 in fair value attributable to noncontrolling interest in Citree, including: (i) approximately $147,500,000 in initial cash consideration funded from the proceeds of the sugarcane disposition and new term loan debt; (ii) $7,500,000 in additional cash consideration released from escrow in equal parts, subject to certain limitations, on December 1, 2015 and June 1, 2016 ; (iii) the refinancing of Orange-Co, LP’s outstanding debt including approximately $92,290,000 in term loan debt and a working capital facility of approximately $27,857,000 and (iv) the assumption of certain other liabilities totaling approximately $4,705,000 . On December 1, 2014 , Alico deposited an irrevocable standby letter of credit issued by Rabo Agrifinance, Inc. in the aggregate amount of $7,500,000 into an escrow account to fund the additional cash consideration. On December 1, 2015 and June 1, 2016, the Company paid $3,750,000 of additional consideration, as contemplated by the Orange-Co Purchase Agreement. The Company's $3,750,000 irrevocable letter of credit securing the final payment of the additional consideration was terminated following the final cash consideration payment. This acquisition was accounted for under the acquisition method of accounting. Accordingly, the Company recognized amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values, while transaction and integration costs associated with the acquisition were expensed as incurred. The excess of the purchase price over the fair value of assets acquired, net of liabilities assumed, and noncontrolling interests is recognized as goodwill. All goodwill recognized will be deductible for income tax purposes. For the fiscal years ended September 30, 2017 and 2016 the Company incurred approximately $0 and $31,000 , respectively, in professional and legal costs in connection with the Orange-Co acquisition. These costs are included in general and administrative expenses in the Consolidated and Combined Statements of Operations. The following table summarizes the final allocation of the acquisition cost to the assets acquired and liabilities assumed at the date of acquisition, based on their estimated fair values: (in thousands) Assets: Amount Accounts receivable $ 888 Other current assets 845 Inventories 35,562 Property and equipment: Citrus Trees 164,123 Land 63,395 Equipment and other facilities 13,431 Goodwill 2,246 Other assets 2,140 Total assets, net of cash acquired $ 282,630 Liabilities: Accounts payable and accrued liabilities $ 4,205 Debt 500 Contingent consideration 7,500 Total liabilities assumed $ 12,205 Assets acquired less liabilities assumed $ 270,425 Less: fair value attributable to noncontrolling interest (4,838 ) Total purchase consideration $ 265,587 Cash proceeds from sugarcane disposition $ 97,126 Working capital line of credit 27,857 Term loans 140,604 Total purchase consideration $ 265,587 The unaudited pro-forma information below for the fiscal years ended September 30, 2015 and 2014 gives effect to this acquisition as if the acquisitions had occurred on October 1, 2013 . The pro-forma financial information is not necessarily indicative of the results of operations if the acquisition had been effective as of this date. (in thousands except per share amounts) Fiscal Year Ended September 30, 2015 2014 (unaudited) Revenues $ 153,654 $ 175,420 Income from operations $ 19,489 $ 35,450 Net income attributable to Alico Inc. common stockholders $ 12,723 $ 22,906 Basic earnings per common share $ 1.58 $ 3.12 Diluted earnings per common share $ 1.58 $ 3.12 Deferred Gain on Sale On November 21, 2014, the Company completed the sale of approximately 36,000 acres of land used for sugarcane production and land leasing in Hendry County, Florida to Global Ag Properties, LLC (“Global”) for approximately $97,900,000 in cash. It had previously leased approximately 30,600 of these acres to United States Sugar Corporation (the “USSC Lease”). The USSC Lease was assigned to Global in conjunction with the land sale. The sales price is subject to post-closing adjustments over a ten year period. The Company realized a gain of approximately $42,753,000 on the sale. Initially, $29,140,000 of the gain was deferred due to the Company’s continuing involvement in the property pursuant to a post-closing agreement and the potential price adjustments. The deferral represents the Company’s estimate of the maximum exposure to loss as a result of the continuing involvement (see below). A net gain of approximately $13,613,000 was recognized at the time of the sale and is recognized in Other (expense) income in the Consolidated Statements of Operations for the fiscal year ended September 30, 2015. The Company estimated its maximum exposure to loss over the ten year period to total approximately $42,172,000 on an aggregate undiscounted basis. This estimated maximum exposure to loss was discounted at five percent to determine the initial deferred gain. In May 2017 and 2016, the Company made payments of $1,580,000 and $1,702,000 , respectively, to Global pursuant to the sales contract. The amount of USSC’s lease is tied to the market price of sugar, and the Company's payment is required annually in advance, to supplement the lease paid by USSC in the event that the sugar prices are below certain thresholds. The 2016 sugar price remained below the threshold and therefore none of the amount advanced in 2016 will be returned to the Company. The Company has recognized approximately $1,413,000 and $1,406,000 in interest expense and approximately $538,000 and $618,000 of the deferred gain for the fiscal years ended September 30, 2017 and 2016, respectively. Deferred gain on sale consists of the following at September 30, 2017 and September 30, 2016: (in thousands) September 30, 2017 2016 Deferred gain on sale $ 27,482 $ 28,440 Annual guarantee payment, net (1,042 ) (1,236 ) Total deferred gain on sale $ 26,440 $ 27,204 Estimated payments over the remaining term of the post-closing agreement are summarized in the following table.

Debt Disclosure [Abstract]
Long-Term Debt and Lines of Credit	Long-Term Debt and Lines of Credit Debt Refinancing The Company refinanced its outstanding debt obligations on December 3, 2014 in connection with the Orange-Co acquisition. These credit facilities initially included $125,000,000 in fixed interest rate term loans (“Met Fixed-Rate Term Loans”), $57,500,000 in variable interest rate term loans (“Met Variable-Rate Term Loans”), a $25,000,000 revolving line of credit (“RLOC”) with Metropolitan Life Insurance Company and New England Life Insurance Company (collectively “Met”), and a $70,000,000 working capital line of credit (“WCLC”) with Rabo Agrifinance, Inc. (“Rabo”). The term loans and RLOC are secured by real property. The security for the term loans and RLOC consists of approximately 38,200 gross acres of citrus groves and 5,762 gross acres of ranch land. The WCLC is collateralized by the Company’s current assets and certain other personal property owned by the Company. The term loans, collectively, are subject to quarterly principal payments of $2,281,250 , and mature November 1, 2029 . The Met Fixed-Rate Term Loans bear interest at 4.15% per annum, and the Met Variable-Rate Term Loans bear interest at a rate equal to 90 day LIBOR plus 165 basis points (the “LIBOR spread”). The LIBOR spread is subject to adjustment by the lender on May 1, 2017 and is subject to further adjustment every two years thereafter until maturity. Interest on the term loans is payable quarterly. The interest rates on the Met Variable-Rate Term Loans were 2.96% per annum and 2.25% per annum as of September 30, 2017 and September 30, 2016 , respectively. The Company may prepay up to $8,750,000 of the Met Fixed-Rate Term Loan principal annually without penalty, and any such prepayments may be applied to reduce subsequent mandatory principal payments. The maximum annual prepayment was made for calendar year 2015 and remains available to reduce future mandatory principal payments if the Company elects to do so. There have been no additional optional prepayments after calendar year 2015. The Met Variable-Rate Term Loans may be prepaid without penalty. The RLOC bears interest at a floating rate equal to 90 day LIBOR plus 165 basis points, payable quarterly. The LIBOR spread was adjusted by the lender on May 1, 2017 and is subject to further adjustment every two years thereafter. Outstanding principal, if any, is due at maturity on November 1, 2019. The RLOC is subject to an annual commitment fee of 25 basis points on the unused portion of the line of credit. The RLOC is available for funding general corporate needs. The variable interest rate was 2.96% per annum and 2.25% per annum as of September 30, 2017 and September 30, 2016 , respectively. Availability under the RLOC was $25,000,000 as of September 30, 2017 . The WCLC is a revolving credit facility and is available for funding working capital and general corporate requirements. The interest rate on the WCLC is based on one month LIBOR, plus a spread, which is adjusted quarterly, based on the Company's debt service coverage ratio for the preceding quarter and can vary from 175 to 250 basis points. The rate is currently at LIBOR plus 175 basis points. The variable interest rate was 2.99% per annum and 2.27% per annum as of September 30, 2017 and September 30, 2016 , respectively. The WCLC agreement was amended on September 6, 2017, and the primary terms of the amendment were an extension of the maturity to November 1, 2019. There were no changes to the commitment amount or interest rate. Availability under the WCLC was approximately $59,700,000 as of September 30, 2017 . The WCLC is subject to a quarterly commitment fee on the daily unused availability under the line computed as the commitment amount less the aggregate of the outstanding loans and outstanding letters of credit. The commitment fee is adjusted quarterly based on Alico's debt service coverage ratio for the preceding quarter and can vary from a minimum of 20 basis points to a maximum of 30 basis points. Commitment fees to date have been charged at 20 basis points. There was no outstanding balance on the WCLC as of September 30, 2017 . The WCLC agreement provides for Rabo to issue up to $20,000,000 in letters of credit on the Company’s behalf. As of September 30, 2017 , there was approximately $10,300,000 in outstanding letters of credit, which correspondingly reduced the Company's availability under the line of credit. In October 2017, Rabo issued two additional letter of credits aggregating approximately $153,000 . In 2014, the Company capitalized approximately $2,834,000 of debt financing costs related to the refinancing. These costs, together with approximately $339,000 of costs related to the retired debt, are being amortized to interest expense over the applicable terms of the loans. Additionally, approximately $123,000 and $78,000 of financing costs were incurred in connection with letters of credit and the amendment of the WCLC, respectively. These costs are also being amortized to interest expense over the applicable terms of the obligations. The unamortized balance of deferred financing costs related to the financing above was approximately $1,656,000 and $1,965,000 at September 30, 2017 and 2016 , respectively. The Company recognized a loss on extinguishment of debt of approximately $964,000 related to the refinancing described above for the fiscal year ended September 30, 2015 . The loss on extinguishment of debt is included in other (expense) income in the Consolidated Statement of Operations for the fiscal year ended September 30, 2015 . The credit facilities above are subject to various covenants including the following financial covenants: (i) minimum debt service coverage ratio of 1.10 to 1.00, (ii) tangible net worth of at least $160,000,000 increased annually by 10% of consolidated net income for the preceding year, or approximately $162,300,000 for the year ending September 30, 2017, (iii) minimum current ratio of 1.50 to 1.00, (iv) debt to total assets ratio not greater than .625 to 1.00, and, solely in the case of the WCLC, (v) a limit on capital expenditures of $30,000,000 per fiscal year. As of September 30, 2017 , the Company was in compliance with these financial covenants. Credit facilities also include a Met Life term loan collateralized by real estate owned by Citree ("Met Citree Loan"). This is a $5,000,000 credit facility that bears interest at a fixed rate of 5.28% per annum. An initial advance of $500,000 was made at closing on March 4, 2014. The loan agreement was amended to provide for an interim advance of $2,000,000 on September 17, 2015, and the interest rate was adjusted to 5.30% per annum at the time of the interim advance. The final $2,500,000 advance was funded on April 27, 2016 and the interest rate was adjusted to 5.28% . The loan matures in February 2029. The unamortized balance of deferred financing costs related to this loan was approximately $49,000 at September 30, 2017 . Silver Nip Citrus Debt There are two fixed-rate term loans, with an original combined balance of $27,550,000 , bearing interest at 5.35% per annum ("Pru Loans A & B"). Principal of $290,000 is payable quarterly, together with accrued interest. The Company may prepay up to $5,000,000 of principal without penalty. On February 15, 2015, Silver Nip Citrus made a prepayment of $750,000 . The loans are collateralized by real estate in Collier, Hardee, Highlands, Martin, Osceola and Polk Counties, Florida and mature June 1, 2033. Silver Nip Citrus entered into two additional fixed-rate term loans with Prudential to finance the acquisition of a 1,500 acre citrus grove on September 4, 2014. Each loan was in the original amount of $5,500,000 . Principal of $55,000 per loan is payable quarterly, together with accrued interest. One loan bears interest at 3.85% per annum (Pru Loan E"), while the other bears interest at 3.45% per annum ("Pru Loan F"). The interest rate on Pru Loan E is subject to adjustment on September 1, 2019 and every year thereafter until maturity. Both loans are collateralized by real estate in Charlotte County, Florida. Pru Note E matures September 1, 2021, and Pru Note F matures September 1, 2039. The Silver Nip Citrus credit agreements were amended on December 1, 2016. The primary terms of the amendments were (1) the Company provided a limited $8,000,000 guaranty of the Silver Nip debt, (2) the limited personal guarantees provided by George Brokaw, Remy W. Trafelet and Clayton Wilson prior to the Company’s merger with Silver Nip Citrus, and also totaling $8,000,000 , were released and (3) the consolidated current ratio covenant requirement, measured on an annual basis, was reduced from 1.50 to 1.00 to 1.00 to 1.00. Silver Nip Citrus was in compliance with the current ratio covenant as of September 30, 2017 , the most recent measurement date. Silver Nip Citrus had a $6,000,000 revolving line of credit with Prudential. This line of credit was paid in full and terminated on April 28, 2015. The Company recognized a loss on extinguishment of debt of approximately $87,000 related to the termination, which is included in other (expense) income on the Consolidated Statements of Operations. The unamortized balance of deferred financing costs related to the Silver Nip Citrus debt was approximately $325,000 at September 30, 2017 . The Silver Nip Citrus facilities are subject to a financial debt covenant requiring a current ratio of at least 1.50 to 1.00, measured at the end of each fiscal year. Silver Nip Citrus was in compliance with this covenant as of September 30, 2017 . Other Modifications of Rabo and Prudential Credit Agreements In February 2015 Rabo agreed, subject to certain conditions, that the Company may loan Silver Nip Citrus up to $7,000,000 on a revolving basis for cash management purposes. These advances would be funded from either cash on hand or draws on the Company’s WCLC.

Inventories	Inventories Inventories consist of the following at September 30, 2017 and September 30, 2016 : (in thousands) September 30, 2017 2016 Unharvested fruit crop on the trees $ 32,145 $ 52,204 Beef cattle 1,954 783 Citrus tree nursery — 3,090 Other 2,105 2,392 Total inventories $ 36,204 $ 58,469 In September 2017, the State of Florida’ citrus business, including the Company’s unharvested citrus crop, were significantly impacted by Hurricane Irma. The impact of Hurricane Irma resulted in the premature drop of unharvested fruit and damage to citrus trees, which we expect to impact future fruit production until such time as the citrus trees recover. We anticipate future fruit production to be impacted in the 2017/2018 and, potentially, the 2018/2019 harvest seasons. The Company undertook a process to estimate the amount of inventory casualty loss as of the date of Hurricane Irma. Such process included a number of factors including: (1) touring all of the citrus groves by operational personnel to assess the estimated fruit drop by grove and the impact of damage to the citrus trees; (2) consideration of independent estimates of the reduced citrus production for the State of Florida; and (3) an estimate of fruit the Company expects to produce for the 2017/2018 harvest season after Hurricane Irma. As a result, the Company recorded a casualty loss to reduce the carrying value of unharvested fruit crop on trees inventory by approximately $13,489,000 . While the Company believes the recorded loss to be its best estimate at this time, additional impairment could result based on the results of the 2017/2018 harvest season. The Company maintains crop insurance and is working closely with its insurers and adjusters to evaluate and determine the amount of insurance recoveries, if any, the Company may be entitled to. The amount of insurance recoveries, if any, will be recorded in the period in which such recoveries are both probable and reasonably estimable. After determining and applying the amount of loss due to shrinkage to the inventory value, the Company evaluated the remaining inventory and determined an additional reduction was necessary in the amount of $1,199,000 to properly reflect the net realizable value of such inventory at September 30, 2017 . The Company reclassified the citrus tree nursery inventory to property and equipment during fiscal 2017.

Business Combinations [Abstract]
Deferred Gain on Sale	Acquisitions and Dispositions Acquisition of Orange-Co, LP Assets On December 2, 2014 , the Company completed the acquisition of certain citrus and related assets of Orange-Co, LP, including 51% of the ownership interests of Citree, pursuant to an Asset Purchase Agreement, which is referred to as the Orange-Co Purchase Agreement, dated as of December 1, 2014 . The assets the Company purchased include approximately 20,263 acres of citrus groves in DeSoto and Charlotte Counties, Florida, which comprise one of the largest contiguous citrus grove properties in the state of Florida. Total assets acquired were approximately $277,792,000 , net of approximately $2,060,000 in cash acquired and approximately $4,838,000 in fair value attributable to noncontrolling interest in Citree, including: (i) approximately $147,500,000 in initial cash consideration funded from the proceeds of the sugarcane disposition and new term loan debt; (ii) $7,500,000 in additional cash consideration released from escrow in equal parts, subject to certain limitations, on December 1, 2015 and June 1, 2016 ; (iii) the refinancing of Orange-Co, LP’s outstanding debt including approximately $92,290,000 in term loan debt and a working capital facility of approximately $27,857,000 and (iv) the assumption of certain other liabilities totaling approximately $4,705,000 . On December 1, 2014 , Alico deposited an irrevocable standby letter of credit issued by Rabo Agrifinance, Inc. in the aggregate amount of $7,500,000 into an escrow account to fund the additional cash consideration. On December 1, 2015 and June 1, 2016, the Company paid $3,750,000 of additional consideration, as contemplated by the Orange-Co Purchase Agreement. The Company's $3,750,000 irrevocable letter of credit securing the final payment of the additional consideration was terminated following the final cash consideration payment. This acquisition was accounted for under the acquisition method of accounting. Accordingly, the Company recognized amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values, while transaction and integration costs associated with the acquisition were expensed as incurred. The excess of the purchase price over the fair value of assets acquired, net of liabilities assumed, and noncontrolling interests is recognized as goodwill. All goodwill recognized will be deductible for income tax purposes. For the fiscal years ended September 30, 2017 and 2016 the Company incurred approximately $0 and $31,000 , respectively, in professional and legal costs in connection with the Orange-Co acquisition. These costs are included in general and administrative expenses in the Consolidated and Combined Statements of Operations. The following table summarizes the final allocation of the acquisition cost to the assets acquired and liabilities assumed at the date of acquisition, based on their estimated fair values: (in thousands) Assets: Amount Accounts receivable $ 888 Other current assets 845 Inventories 35,562 Property and equipment: Citrus Trees 164,123 Land 63,395 Equipment and other facilities 13,431 Goodwill 2,246 Other assets 2,140 Total assets, net of cash acquired $ 282,630 Liabilities: Accounts payable and accrued liabilities $ 4,205 Debt 500 Contingent consideration 7,500 Total liabilities assumed $ 12,205 Assets acquired less liabilities assumed $ 270,425 Less: fair value attributable to noncontrolling interest (4,838 ) Total purchase consideration $ 265,587 Cash proceeds from sugarcane disposition $ 97,126 Working capital line of credit 27,857 Term loans 140,604 Total purchase consideration $ 265,587 The unaudited pro-forma information below for the fiscal years ended September 30, 2015 and 2014 gives effect to this acquisition as if the acquisitions had occurred on October 1, 2013 . The pro-forma financial information is not necessarily indicative of the results of operations if the acquisition had been effective as of this date.

It had previously leased approximately 30,600 of these acres to United States Sugar Corporation (the “USSC Lease”). The USSC Lease was assigned to Global in conjunction with the land sale. The sales price is subject to post-closing adjustments over a ten year period. The Company realized a gain of approximately $42,753,000 on the sale. Initially, $29,140,000 of the gain was deferred due to the Company’s continuing involvement in the property pursuant to a post-closing agreement and the potential price adjustments. The deferral represents the Company’s estimate of the maximum exposure to loss as a result of the continuing involvement (see below). A net gain of approximately $13,613,000 was recognized at the time of the sale and is recognized in Other (expense) income in the Consolidated Statements of Operations for the fiscal year ended September 30, 2015. The Company estimated its maximum exposure to loss over the ten year period to total approximately $42,172,000 on an aggregate undiscounted basis. This estimated maximum exposure to loss was discounted at five percent to determine the initial deferred gain. In May 2017 and 2016, the Company made payments of $1,580,000 and $1,702,000 , respectively, to Global pursuant to the sales contract. The amount of USSC’s lease is tied to the market price of sugar, and the Company's payment is required annually in advance, to supplement the lease paid by USSC in the event that the sugar prices are below certain thresholds. The 2016 sugar price remained below the threshold and therefore none of the amount advanced in 2016 will be returned to the Company. The Company has recognized approximately $1,413,000 and $1,406,000 in interest expense and approximately $538,000 and $618,000 of the deferred gain for the fiscal years ended September 30, 2017 and 2016, respectively.

Common Stock and Options	Common Stock and Options Effective January 27, 2015, the Company’s Board of Directors adopted the 2015 Stock Incentive Plan (the “2015 Plan”) which provides for up to an additional 1,250,000 common shares available for issuance to provide a long-term incentive plan for officers, employees, directors and/or consultants to directly link incentives to stockholder value. The 2015 Plan was approved by the Company’s stockholders in February 2015. The Company’s 2015 Plan provides for grants to executives in various forms including restricted shares of the Company’s common stock and stock options. Awards are discretionary and are determined by the Compensation Committee of the Board of Directors. Awards vest based upon service conditions. Non-vested restricted shares generally vest over requisite service periods of one to six years from the date of grant. Restricted Stock In fiscal year 2015, the Company awarded 12,500 restricted shares of the Company’s common stock (“Restricted Stock”) to two senior executives under the 2015 Plan at a weighted average fair value of $49.49 per common share, vesting over three to five years. A summary of the status of the Company’s nonvested shares is as follows: Nonvested Shares Shares Weighted-Average Grant Date Fair Value Nonvested Shares at September 30, 2014 — — Granted during fiscal 2015 12,500 $ 49.49 Vested during 2015 fiscal — — Forfeited during fiscal 2015 — — Nonvested Shares at September 30, 2015 12,500 $ 49.49 Granted during fiscal 2016 — — Vested during 2016 fiscal (2,333 ) $ 49.50 Forfeited during fiscal 2016 — — Nonvested Shares at September 30, 2016 10,267 $ 49.49 Granted during fiscal 2017 — — Vested during fiscal 2017 (4,933 ) $ 49.58 Forfeited during fiscal 2017 — — Nonvested Shares at September 30, 2017 5,334 $ 49.39 Stock compensation expense related to the Restricted Stock totaled approximately $264,000 and $150,000 for the fiscal year ended September 30, 2017 and 2016, respectively. There was approximately $149,000 and $413,000 of total unrecognized stock compensation costs related to nonvested stock compensation for the Restricted Stock grants at September 30, 2017 and 2016, respectively. The unrecognized stock compensation will be fully expensed in fiscal year ended September 2018. Stock Options A stock option grant of 300,000 options in the case of Mr. Trafelet and 225,000 options in the case of each of Messrs. Slack and Brokaw (collectively, the “Option Grants”) were granted on December 31, 2016. The option price was set at $27.15 , the closing price on December 31, 2016. The Option Grants will vest as follows: (i) 25% of the options will vest if the price of the Company’s common stock during a consecutive 20 -trading day period exceeds $60.00 ; (ii) 25% of the options will vest if such price exceeds $75.00 ; (iii) 25% of the options will vest if such price exceeds $90.00 ; and (iv) 25% of the options will vest if such price exceeds $105.00 . If the applicable stock price hurdles have not been achieved by (A) the second anniversary of the Executive’s termination of employment, if the Executive’s employment is terminated due to death or disability, (B) the date that is 18 months following the Executive’s termination of employment, if the Executive’s employment is terminated by the Company without cause, by the Executive with good reason, or due to the Executive’s retirement, or (C) the date of the termination of the Executive’s employment for any other reason, then any unvested options will be forfeited. In addition, if the applicable stock price hurdles have not been achieved by the fifth anniversary of the grant date (or the fourth anniversary of the grant date, in the case of the tranche described in clause (i) above), then any unvested options will be forfeited. The Option Grants will also become vested to the extent that the applicable stock price hurdles are satisfied in connection with a change in control of the Company. As of September 30, 2017, the Company’s stock was trading at $34.15 per share and during fiscal 2017 the stock did not trade above $34.45 per share; accordingly, none of the stock options are vested at September 30, 2017.

At September 30, 2017 there was approximately $2,030,000 to total unrecognized stock compensation costs related to nonvested share-based compensation for the option grants. The fair value of the Option Grants was estimated on the date of grant using a Monte Carlo valuation model that uses the assumptions noted in the following table. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding; the range given below results from different time-frames for the various market conditions being met. Expected Volatility 32.19 % Expected Term (in years) 2.6 - 4.0 Risk Free Rate 2.45 % The weighted-average grant-date fair value of the Option Grants was $3.53 . There were no additional stock options granted, exercised or forfeited for the fiscal year ended September 30, 2017 . As of September 30, 2017, there were 487,500 common shares available for issuance under the 2015 Plan.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company complies with the provisions of FASB ASC 820 “Fair Value Measurements” for its financial and non-financial assets and liabilities. ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. The majority of the carrying amounts of the Company’s assets and liabilities including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities as of September 30, 2017 and 2016 , approximate their fair value because of the immediate or short term maturity of these financial instruments. The carrying amounts reported for long-term debt approximates fair value as the Company’s borrowings with commercial lenders are at interest rates that vary with market conditions and fixed rates that approximate market rates for similar obligations. The majority of our non-financial instruments, which include inventories and property and equipment, are not required to be carried at fair value on a recurring basis. The Company does have certain assets classified as Assets Held for Sale which have been recorded at the lower of carrying value or the estimated fair value less costs to sell. ASC 820 clarifies that fair value is an exit price representing the amount that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows: • Level 1- Observable inputs such as quoted prices in active markets; • Level 2- Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and • Level 3- Unobservable inputs in which there is little or no market data, such as internally-developed valuation models which require the reporting entity to develop its own assumptions. The following table represents certain assets held for sale as of September 30, 2017 , which have been measured at fair value on a non-recurring basis (see Note 6. for complete listing of assets held for sale): Fair Value Hierarchy Carrying Value Adjustment to Fair Value Fair Value Nursery - Gainsville Level 3 $ 10,107 $ 3,607 $ 6,500 Chancey Bay Level 3 $ 4,587 $ 408 $ 4,179 Trailers Level 3 $ 1,278 $ 116 $ 1,162 There were no gains or losses included in earnings attributable to changes in unrealized gains or losses relating to our assets as of September 30, 2017 and 2016 . We use third-party service providers to assist in the evaluation of investments. For investment valuations, current market interest rates, quality estimates by rating agencies and valuation estimates by active market participants were used to determine values. Deferred retirement benefits were valued based on actuarial data, contracted payment schedules and an estimated discount rate of 4.08% and 4.30% as of September 30, 2017 and 2016 , respectively.

Segment Reporting [Abstract]
Segment Information	Segment Information Segments Operating segments are defined in the criteria established under the Financial Accounting Standards Board - Accounting Standards Codification (“FASB ASC”) Topic 280 as components of public entities that engage in business activities from which they may earn revenues and incur expenses for which separate financial information is available and which is evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to assess performance and allocate resources.

Total revenues represent sales to unaffiliated customers, as reported in the Consolidated Statements of Operations. Goods and services produced by these segments are sold to wholesalers and processors in the United States who prepare the products for consumption. The Company evaluates the segments’ performance based on direct margins (gross profit) from operations before general and administrative expenses, interest expense, other income (expense) and income taxes, not including nonrecurring gains and losses. Information by operating segment is as follows: (in thousands) Fiscal Year Ended September 30, 2017 2016 2015 Revenues: Alico Citrus $ 123,441 $ 137,282 $ 146,147 Conservation and Environmental Resources 4,793 5,669 5,394 Other Operations 1,595 1,245 1,585 Total revenues 129,829 144,196 153,126 Operating expenses: Alico Citrus 111,947 102,347 110,777 Conservation and Environmental Resources 8,814 6,393 4,808 Other Operations 138 397 2,083 Total operating expenses 120,899 109,137 117,668 Gross profit (loss): Alico Citrus 11,494 34,935 35,370 Conservation and Environmental Resources (4,021 ) (724 ) 586 Other Operations 1,457 848 (498 ) Total gross profit (loss) $ 8,930 $ 35,059 $ 35,458 Capital expenditures: Alico Citrus $ 11,738 $ 10,393 $ 9,403 Conservation and Environmental Resources 646 1,664 1,461 Other Operations — 629 162 Other Capital Expenditures 969 1,619 497 Total capital expenditures $ 13,353 $ 14,305 $ 11,523 Depreciation, depletion and amortization: Alico Citrus $ 14,054 $ 13,982 $ 12,297 Conservation and Environmental Resources 585 456 1,275 Other Operations 67 476 471 Other Depreciation, Depletion and Amortization 520 468 689 Total depreciation, depletion and amortization $ 15,226 $ 15,382 $ 14,732 (in thousands) September 30, 2017 2016 Assets: Alico Citrus $ 387,972 $ 410,663 Conservation and Environmental Resources 13,845 13,073 Other Operations 10,974 22,050 Other Corporate Assets 6,391 9,659 Total Assets $ 419,182 $ 455,445

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefits Plans Management Security Plan The management security plan (“MSP”) is a nonqualified, noncontributory defined supplemental deferred retirement benefit plan for a select group of management personnel. The MSP provides a fixed supplemental retirement benefit for 180 months . The MSP is frozen; no new participants are being added and no benefit increases are being granted. The MSP benefit expense and the projected management security plan benefit obligation are determined using assumptions as of the end of the year. The weighted-average discount rate used to compute the obligation was 4.08% and 4.30% in fiscal years 2017 and 2016 , respectively. Actuarial gains or losses are recognized when incurred, therefore; the end of year benefit obligation is the same as the accrued benefit costs recognized in the Consolidated Balance Sheets. The amount of MSP benefit expense charged to costs and expenses was as follows: (in thousands) Fiscal Year Ended September 30, 2017 2016 2015 Service cost $ 200 $ 213 $ 195 Interest cost 140 210 197 Recognized actuarial loss adjustment (78 ) (5 ) 231 Total $ 262 $ 418 $ 623 The following provides a roll-forward of the MSP benefit obligation: (in thousands) September 30, 2017 2016 Change in projected benefit obligation: Benefit obligation at beginning of year $ 4,543 $ 4,476 Service cost 200 213 Interest cost 140 210 Benefits paid (367 ) (351 ) Recognized actuarial loss adjustment (78 ) (5 ) Benefit obligation at end of year $ 4,438 $ 4,543 Funded status at end of year $ (4,438 ) $ (4,543 ) The MSP is unfunded and benefits are paid as they become due. The estimated future benefit payments under the plan for each of the five succeeding years are approximately $348,000 , $357,000 , $160,000 , $192,000 , and $192,000 for the five-year period thereafter is an aggregate of $1,249,000 . The Company has established a “Rabbi Trust” to provide for the funding of accrued benefits under the MSP. According to the terms of the Rabbi Trust, funding is voluntary until a change of control of the Company as defined in the Management Security Plan Trust Agreement occurs. Upon a change of control, funding is triggered. As of September 30, 2017 , the Rabbi Trust had no assets, and no change of control had occurred.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared the accompanying financial statements on a consolidated basis. These accompanying Consolidated Financial Statements, which are referred to herein as the “Financial Statements”, have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying Financial Statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the Company’s results as of and for the fiscal years ended September 30, 2017 and 2016 . All significant intercompany transactions and account balances between the consolidated businesses have been eliminated.
Segments	Segments Operating segments are defined in the criteria established under the Financial Accounting Standards Board - Accounting Standards Codification (“FASB ASC”) Topic 280 as components of public entities that engage in business activities from which they may earn revenues and incur expenses for which separate financial information is available and which is evaluated regularly by the Company’s chief operating decision maker (“CODM”) in deciding how to assess performance and allocate resources. The Company’s CODM assesses performance and allocates resources based on three operating segments: Alico Citrus (formerly Orange Co.), Conservation and Environmental Resources and Other Operations.
Principles of Consolidation and Noncontrolling Interest in Consolidated Affiliate	Principles of Consolidation The Financial Statements include the accounts of Alico, Inc. and the accounts of all the subsidiaries in which a controlling interest is held by the Company. Under U.S. GAAP, consolidation is generally required for investments of more than 50% of the outstanding voting stock of an investee, except when control is not held by the majority owner. The Company’s subsidiaries include: Alico Land Development, Inc., Alico-Agri, Ltd., Alico Plant World, LLC, Alico Fruit Company, LLC, Alico Citrus Nursery, LLC, Alico Chemical Sales, LLC, 734 Citrus Holdings LLC and subsidiaries, Alico Fresh Fruit LLC, Alico Skink Mitigation, LLC and Citree Holdings 1, LLC. The Company considers the criteria established under FASB ASC Topic 810, “Consolidations” in its consolidation process. All significant intercompany balances and transactions have been eliminated in consolidation. Noncontrolling Interest in Consolidated Affiliate The Financial Statements include all assets and liabilities of the less-than- 100% -owned affiliate the Company controls, Citree Holdings I, LLC (“Citree”). Accordingly, the Company has recorded a noncontrolling interest in the equity of such entity.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities as of the date of the accompanying Financial Statements, the disclosure of contingent assets and liabilities in the Financial Statements and the accompanying Notes, and the reported amounts of revenues and expenses and cash flows during the periods presented. Actual results could differ from those estimates based upon future events. The Company evaluates estimates on an ongoing basis. The estimates are based on current and expected economic conditions, historical experience, the experience and judgment of the Company’s management and various other specific assumptions that the Company believes to be reasonable. The Company evaluates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in the Company’s evaluations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standard Update ("ASU") 2014-09, “Revenue from Contracts with Customers,” as a new ASC topic (Topic 606). The core principle of this ASU is that an entity should recognize revenue 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. The ASU further provides guidance for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (for example, lease contracts). The FASB subsequently issued ASU 2015-14 to defer the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with earlier adoption permitted. The FASB also recently issued ASU 2016-10, "Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing," and 2016-12, "Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients," that clarify or amend the original Topic 606. ASU 2014-09 can be adopted using one of two retrospective transition methods: 1) retrospectively to each prior reporting period presented or 2) as a cumulative-effect adjustment as of the date of adoption. The Company has not yet selected a transition method and is currently evaluating the impact of ASU 2014-09 on the Company’s Financial Statements upon adoption. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)." This guidance will require entities that enter into leases as a lessee to recognize right-of-use assets and lease liabilities for those leases classified as operating leases under previous GAAP. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. The Company is currently evaluating the impact this guidance will have on our Financial Statements, and it will become effective for Alico at the beginning of its first quarter of fiscal 2020. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." The amendment clarifies the implementation guidance for principal versus agent considerations as contained in ASU No. 2014-09, Revenue from Contracts with Customers. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to a customer. ASU No. 2016-08 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption of ASU No. 2016-08 is permitted but not before December 15, 2016. The Company is currently evaluating the impact of ASU No. 2016-08 on our Financial Statements. In March 2016, the FASB issued ASU 2016-09, “Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The objective of this update is to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. This guidance, which will be adopted October 1, 2017, is not expected to have a significant impact on our Financial Statements In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” This ASU will provide guidance on the presentation and classification of specific cash flow items to improve consistency within the statement of cash flows. The effective date for adoption of this guidance would be our fiscal year beginning October 1, 2018, with early adoption permitted. The Company is currently evaluating the effect that ASU 2016-15 will have on our Financial Statements. In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” (ASC Topic 740, Income Taxes), which will require an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This ASU is effective for the Company on October 1, 2018 with early adoption permitted. The Company has not yet evaluated the effect, if any, that ASU 2016-16 will have on our Financial Statements. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" that provides guidance to assist entities with evaluating when a set of transferred assets and activities (set) is a business. Under the new guidance, an entity first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. The ASU will be applied prospectively to any transactions occurring within the period of adoption. Early adoption is permitted. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other” (Topic 350) which simplifies the accounting for goodwill impairment. The updated guidance eliminates Step 2 of the impairment test, which requires entities to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value, determined in Step 1. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. We will adopt this guidance using a prospective approach. Earlier adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" (Subtopic 610-20): The ASU clarifies that ASC 610-20 applies to the derecognition of nonfinancial assets and in substance nonfinancial assets unless other specific guidance applies. As a result, it will not apply to the derecognition of businesses, nonprofit activities, or financial assets (including equity method investments), or to contracts with customers. The ASU also clarifies that an in substance nonfinancial asset is an asset or group of assets for which substantially all of the fair value consists of nonfinancial assets and the group or subsidiary is not a business. In addition, transfers of nonfinancial assets to another entity in exchange for a noncontrolling ownership interest in that entity will be accounted for under ASC 610-20, removing specific guidance on such partial exchanges from ASC 845, Nonmonetary Transactions . As a result, guidance specific to real estate sales in ASC 360-20 will be eliminated. As such, sales and partial sales of real estate assets will now be subject to the same derecognition model as all other nonfinancial assets. The ASU will also impact the accounting for partial sales of nonfinancial assets (including in substance real estate). When an entity transfers its controlling interest in a nonfinancial asset, but retains a noncontrolling ownership interest, the entity will measure the retained interest at fair value. This will result in full gain/loss recognition upon the sale of a controlling interest in a nonfinancial asset. Current guidance generally prohibits gain recognition on the retained interest. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years and early adoption is permitted. The ASU will be applied prospectively to any transaction occurring from the date of adoption. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation” (Topic 718) which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. We do not expect this new guidance to have a material impact on our consolidated financial statements. The Company has reviewed other recently issued accounting standards which have not yet been adopted in order to determine their potential effect, if any, on the results of operations or financial condition. Based on the review of these other recently issued standards, the Company does not currently believe that any of those accounting pronouncements will have a significant effect on its current or future financial position, results of operations, cash flows or disclosures.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified in the accompanying Financial Statements for consistent presentation to the current period. These reclassifications had no impact on net income, equity or cash flows as previously reported; however, working capital decreased by approximately $1,184,000 at September 30, 2016 .
Seasonality	Seasonality The Company is primarily engaged in the production of fruit for sale to citrus markets, which is of a seasonal nature, and subject to the influence of natural phenomena and wide price fluctuations. Historically, the second and third quarters of our fiscal year generally produce the majority of our annual revenue, and working capital requirements are typically greater in the first and fourth quarters of the fiscal year. The results of the reported periods herein are not necessarily indicative of the results for any other interim periods or the entire fiscal year. Revenue Recognition Revenues from agricultural crops are recognized at the time the crop is harvested and delivered to the customer. Receivables from crops sold are recorded for the estimated proceeds to be received from the customer. On a quarterly basis, management reviews the reasonableness of the revenues accrued based on buyers’ and processors’ advances to growers, cash and futures markets and experience in the industry. Adjustments are made throughout the year to these estimates as more current relevant industry information becomes available. Differences between the estimates and the final realization of revenues can be significant and can be either an increase or decrease to reported revenues. During the periods presented in this report, no material adjustments were made to the reported revenues of the Company’s crops. Alico recognizes revenues from cattle sales at the time the cattle are delivered. Alico Fruit Company, LLC ("AFC") operations primarily consist of providing supply chain management services to Alico, as well as to other citrus growers and processors in the state of Florida. AFC also purchases and resells citrus fruit; in these transactions, AFC (i) acts as a principal; (ii) takes title to the products; and (iii) has the risks and rewards of ownership, including the risk of loss for collection, delivery or returns. Therefore, AFC recognizes revenues based on the gross amounts due from customers for its marketing activities. Supply chain management services revenues are recognized when the services are performed.

Accounting Policies [Abstract]
Business Combinations	Business Combinations The Company accounts for its business acquisitions under the acquisition method of accounting as indicated in FASB ASC 805, “Business Combinations”, which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed and any noncontrolling interest in the acquiree, and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities and noncontrolling interest in the acquiree, based on fair value estimates as of the date of acquisition. In accordance with FASB ASC 805, the Company recognizes and measures goodwill, if any, as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. When we acquire a business from an entity under common control, whereby the companies are ultimately controlled by the same party or parties both before and after the transaction, it is treated similar to the pooling of interests method of accounting. The assets and liabilities are recorded at the transferring entity’s historical cost instead of reflecting the fair value of assets and liabilities.
Revenue Recognition	Seasonality The Company is primarily engaged in the production of fruit for sale to citrus markets, which is of a seasonal nature, and subject to the influence of natural phenomena and wide price fluctuations. Historically, the second and third quarters of our fiscal year generally produce the majority of our annual revenue, and working capital requirements are typically greater in the first and fourth quarters of the fiscal year. The results of the reported periods herein are not necessarily indicative of the results for any other interim periods or the entire fiscal year. Revenue Recognition Revenues from agricultural crops are recognized at the time the crop is harvested and delivered to the customer. Receivables from crops sold are recorded for the estimated proceeds to be received from the customer. On a quarterly basis, management reviews the reasonableness of the revenues accrued based on buyers’ and processors’ advances to growers, cash and futures markets and experience in the industry. Adjustments are made throughout the year to these estimates as more current relevant industry information becomes available. Differences between the estimates and the final realization of revenues can be significant and can be either an increase or decrease to reported revenues. During the periods presented in this report, no material adjustments were made to the reported revenues of the Company’s crops. Alico recognizes revenues from cattle sales at the time the cattle are delivered. Alico Fruit Company, LLC ("AFC") operations primarily consist of providing supply chain management services to Alico, as well as to other citrus growers and processors in the state of Florida. AFC also purchases and resells citrus fruit; in these transactions, AFC (i) acts as a principal; (ii) takes title to the products; and (iii) has the risks and rewards of ownership, including the risk of loss for collection, delivery or returns. Therefore, AFC recognizes revenues based on the gross amounts due from customers for its marketing activities. Supply chain management services revenues are recognized when the services are performed.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short term and immediate nature of these financial instruments. The carrying amounts of our debt approximates fair value as the debt is with commercial lenders at interest rates that vary with market conditions or have fixed rates that approximate market rates for obligations with similar terms and maturities
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers cash in banks and highly liquid instruments with an original maturity of three months or less to be cash and cash equivalents.
Accounts receivable	Accounts receivable Accounts receivable from customers are generated from revenues based on the sale of citrus, cattle, leasing and other transactions. The Company grants credit in the course of its operations to third party customers. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. The Company provides an allowance for doubtful accounts for amounts which are not probable of collection. The estimate, evaluated quarterly by the Company, is based on historical collection experience, current macroeconomic climate and market conditions and a review of the current status each customer’s account. Changes in the financial viability of significant customers and worsening of economic conditions may require changes to its estimate of the recoverability of the receivables. Such changes in estimates are recorded in the period in which these changes become known. The allowance for doubtful accounts is included in general and administrative expenses in the Consolidated Statements of Operations.
Concentrations	The citrus industry is subject to various factors over which growers have limited or no control, including weather conditions, disease, pestilence, water supply and market price fluctuations. Market prices are highly sensitive to aggregate domestic and foreign crop sizes, as well as factors including, but not limited to, weather and competition from foreign countries. Concentrations
Real Estate	Real Estate In recognizing revenues from land sales, the Company applies specific revenue recognition criteria, in accordance with U.S. GAAP, to determine when land sales revenues can be recorded. For example, in order to fully recognize a gain resulting from a real estate transaction, the sale must be consummated with a sufficient down payment of at least 20% to 25% of the sales price depending upon the type and timeframe for development of the property sold and any receivable from the sale cannot be subject to future subordination. In addition, the seller cannot retain any material continuing involvement in the property sold. When these criteria are not met, the Company recognizes a gain proportionate to collections utilizing either the installment method or deposit method as appropriate.
Inventories	Inventories The costs of growing crops, including but not limited to labor, fertilization, fuel, crop nutrition and irrigation, are capitalized into inventory throughout the respective crop year. Such costs are expensed as cost of sales when the crops are harvested and are recorded as operating expenses in the Consolidated Statements of Operations. Inventories are stated at the lower of cost or net realizable value. The cost for unharvested citrus crops is based on accumulated production costs incurred during the period from January 1 through the balance sheet date. The cost of the beef cattle inventory is based on the accumulated cost of developing such animals for sale from July 1 through the balance sheet date
Property and Equipment	Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation, depletion and amortization. Major improvements are capitalized while expenditures for maintenance and repairs are expensed when incurred. Costs related to the development of citrus groves through planting of trees are capitalized. Such costs include land clearing, excavation and construction of ditches, dikes, roads, and reservoirs, among other costs. After the planting, caretaking costs or pre-productive maintenance costs are capitalized for four years. After four years, a planting is considered to have reached maturity and the accumulated costs are depreciated over 25 years, except for land clearing and excavation, which are considered costs of land and not depreciated. The breeding herd consists of purchased animals and animals raised on the Company’s ranches. Purchased animals are stated at the cost of acquisition. The cost of animals raised on the ranch is based on the accumulated cost of developing such animals for productive use. Real estate costs incurred for the acquisition, development and construction of real estate projects are capitalized. Depreciation is provided on a straight-line basis over the estimated useful lives of the depreciable assets, with the exception of leasehold improvements and assets acquired through capital leases, which are depreciated over their estimated useful lives if the lease transfers ownership or contains a bargain purchase option, otherwise the term of the lease. Changes in circumstances, such as technological advances or changes to our business model or capital strategy could result in the actual useful lives differing from the original estimates. In those cases where we determine that the useful life of property and equipment should be shortened, we would depreciate the asset over its revised estimated remaining useful life, thereby increasing depreciation expense
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. The Company records impairment losses on long-lived assets used in operations, or asset group, when events and circumstances indicate that the assets might be impaired and the estimated cash flows (undiscounted and without interest charges) to be generated by those assets or asset group over the remaining lives of the assets or asset group are less than the carrying amounts of those assets. In calculating impairments and the estimated cash flows, the Company assigns its asset groups by determining the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of the other Company assets. The net carrying values of assets or asset group not recoverable are reduced to their fair values. Our cash flow estimates are based on historical results adjusted to reflect our best estimates of future market conditions and operating conditions.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price of acquired businesses over the fair value of the assets acquired less liabilities assumed in connection with such acquisition. In accordance with the provisions of ASC 350, Intangibles-Goodwill and Other, goodwill and intangible assets with indefinite useful lives acquired in an acquisition are not amortized, but instead are tested for impairment at least annually, on the same date, or more frequently should an event occur or circumstances indicate that the carrying amount may be impaired. Such events or circumstances may be a significant change in business climate, economic and industry trends, legal factors, negative operating performance indicators, significant competition, changes in strategy or disposition of a reporting unit or a portion thereof. In the evaluation of goodwill for impairment, we have the option to perform a qualitative assessment to determine whether further impairment testing is necessary or to perform a quantitative assessment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. Under the qualitative assessment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. If, under the quantitative assessment, the fair value of a reporting unit is less than its carrying amount, then the amount of the impairment loss, if any, must be measured under step two of the impairment analysis. In step two of the analysis, we would record an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, should such a circumstance arise.
Other Non-Current Assets	Other Non-Current Assets Other non-current assets primarily include investments owned in agricultural cooperatives, cash surrender value on life insurance and equity investment in affiliate (Magnolia). Investments in stock related to agricultural cooperatives are carried at cost.
Income Taxes	Income Taxes The Company uses the asset and liability method of accounting for deferred income taxes. The provision for income taxes includes income taxes currently payable and those deferred as a result of temporary differences between the financial statements and the income tax basis of assets and liabilities. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income or loss in the period that includes the enactment date. A valuation allowance is provided to reduce deferred tax assets to the amount of future tax benefit when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Projected future taxable income and ongoing tax planning strategies are considered and evaluated when assessing the need for a valuation allowance. Any increase or decrease in a valuation allowance could have a material adverse or beneficial impact on the Company’s income tax provision and net income or loss in the period the determination is made. As of September 30, 2017 and 2016 , the Company did not record a valuation allowance on deferred tax assets. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. The Company records interest related to unrecognized tax benefits in income tax expense.
Earnings per Share	Earnings per Share Basic earnings per share for our common stock is calculated by dividing net income attributable to Alico common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per common share is similarly calculated, except that the calculation includes the dilutive effect of the assumed issuance of shares of common stock issuable under equity-based compensation plans in accordance with the treasury stock method, or any other type of securities convertible into common stock, except where the inclusion of such common shares would have an anti-dilutive effect.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is measured based on the fair value of the equity award at the grant date and is typically expensed on a straight-line basis over the vesting period. Upon the vesting of restricted stock, the Company issues common stock from common shares held in treasury.
Equity Method Investments and Variable Interest Entities	Equity Method Investments and Variable Interest Entities The Company evaluates the method of accounting for investments in which it does not hold an equity interest of at least 50% based on the amount of control it exercises over the operations of the investee, exposure to losses in excess of its investment, the ability to significantly influence the investee and whether the Company is the primary beneficiary of the investee. Investments not qualifying for consolidation are accounted for under the equity method whereby the ongoing investment in the entity, consisting of its initial investment adjusted for distributions, gains and losses of the entity are classified as a single line in the balance sheet and as a non-operating item in the statements of operation.
