All significant intercompany transactions and balances have been eliminated in consolidation. Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In preparing these financial statements, management has made estimates with regard to goodwill and other long-lived assets, stock compensation and deferred tax assets. Actual results could differ from those estimates. Revenue Recognition The Company recognizes rental income through its lease with Fenner Valley Farms LLC. Stock-Based Compensation General and administrative expenses include $ 2.3 $1.3 $1.1 December 31, 2017, 2016 2015, The Company applies the Black-Scholes valuation model in determining the fair value of options granted to employees and consultants. For employees, the fair value is then charged to expense on the straight-line basis over the requisite service period. For consultants, the fair value is remeasured at each reporting period and recorded as a liability until the award is settled.
