Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The summarized information of Tejon Ranch Co. and its subsidiaries, (the Company, Tejon, we, us and our), furnished pursuant to the instructions to Part I of Form 10-Q is unaudited and reflects all adjustments which are, in the opinion of the Company’s management, necessary for a fair statement of the results for the interim period. All such adjustments are of a normal recurring nature. We have evaluated subsequent events through the date of issuance of our consolidated financial statements. The periods ending March 31, 2017 and 2016 include the consolidation of Centennial Founders, LLC’s statement of operations within the resort /residential real estate development segment and statements of cash flows. The Company’s March 31, 2017 and December 31, 2016 balance sheets and statements of changes in equity and noncontrolling interests are presented on a consolidated basis including the consolidation of Centennial Founders, LLC. The Company has identified five reportable segments: commercial/industrial real estate development, resort/residential real estate development, mineral resources, farming, and ranch operations. Information for the Company’s reported segments is presented in its Consolidated Statements of Operations. The Company’s reporting segments follow the same accounting policies used for the Company’s consolidated financial statements. We use segment profit or loss, along with equity in earnings of unconsolidated joint ventures, as the primary measure of profitability to evaluate operating performance and to allocate capital resources. The results of the period reported herein are not indicative of the results to be expected for the full year due to the seasonal nature of the Company’s agricultural activities and timing of real estate sales and leasing activities. Historically, the Company’s largest percentages of farming revenues are recognized during the third and fourth quarters of the fiscal year. For further information and a summary of significant accounting policies, refer to the Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board, or FASB, issued Account Standards Update, or ASU, 2016-01, "Financial Statements - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which requires equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. There will no longer be an available-for-sale classification for equity securities with readily determinable fair values. The new guidance is effective for periods beginning after December 15, 2017, with early adoption permitted. The Company is currently in the process of evaluating the impact of the adoption of this ASU on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." From the lessee's perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessee. From the lessor's perspective, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing lease. If the lessor doesn’t convey risks and rewards or control, an operating lease results. ASU 2016-02 is effective for periods beginning after December 15, 2018. The Company is currently in the process of evaluating the impact of the adoption of this ASU on the Company’s consolidated financial statements. In March 2016, the FASB issued an ASU No. 2016-08, "Revenue from Contracts with Customers" that further clarifies an ASU issued in 2014 on recognition of revenue arising from contracts with customers. The core principle of this ASU is that entities will recognize revenue to represent the transfer of goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in such exchange. Leases are specifically excluded from this ASU and will be governed by the applicable lease codification. However, this update may have implications in certain variable payment terms included in lease agreements and in sale and leaseback transactions. The ASU is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2017. The Company's preliminary assessment of revenues from contracts yielded an immaterial impact to the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Compensation—Stock Compensation (Topic 718) — Improvements to Employee Share-Based Payment Accounting." The ASU is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016. Stock-based compensation excess tax benefits or deficiencies are now reflected in the Consolidated Statements of Operations as a component of the provision for income taxes, whereas previously they were recognized within additional paid-in-capital. On the Consolidated Statements of Cash Flows, excess tax benefits or deficiencies associated with stock compensation should be classified as an operating activity. We applied both amendments prospectively within the Consolidated Statements of Operations and Consolidated Statements of Cash Flows recognizing excess tax deficiencies of $142,000. This change has no impact on total shareholders’ equity. The amendment also clarifies that cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity within the Consolidated Statements of Cash Flows. This approach is consistent with our existing policy and as such no changes were made to the Consolidated Statements of Cash Flows. Lastly, the ASU also allows for forfeitures to be recorded when they occur rather than estimated over the vesting period. However, we will continue to estimate forfeitures over the vesting period. In August 2016, the FASB issued ASU No. 2016-15 “Statement of Cash Flows (Topic 230),” or ASU 2016-15. ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The new guidance addresses the classification of various transactions including distributions received from equity method investments. The new guidance allows companies to adopt the cumulative earnings or nature of distribution for classifying distributions received from equity method investments. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively. The Company is currently in the process of evaluating the impact of the adoption of this ASU on the Company’s consolidated financial statements.
