Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. On an ongoing basis, the Company evaluates its estimates, including those related to stock-based compensation and the valuation allowance for deferred tax assets and derivatives. The Company bases its estimates on historical experience and on various other market-specific and relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents consist of cash and term deposits with original maturities of three months or less. The carrying value of these instruments approximate fair value. The balances, at times, may exceed federally insured limits. The Company has not experienced any losses on its cash and cash equivalents. Trade Accounts Receivable Accounts receivable are unsecured, are recorded at net realizable value, and do not bear interest. The Company makes judgments as to its ability to collect outstanding receivables based upon patterns of collectability, historical experience, and management’s evaluation of specific accounts and will provide an allowance for credit losses when collection becomes doubtful. The Company performs credit evaluations of its customers’ financial condition on an as-needed As of September 30, 2017, the Company had no trade accounts receivables. The Company considered its trade receivables to be fully collectible at December 31, 2016; accordingly, no allowance for doubtful accounts was considered necessary. Prepaid Expenses and Other Current Assets Other current assets represent prepayments, receivable for stock option exercises, R&D tax credits and deposits made by the Company. Property and Equipment Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed based upon the estimated useful lives of the respective assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the assets. Repairs and maintenance costs are expensed as incurred. The cost and accumulated depreciation of property and equipment retired, or otherwise disposed of, are removed from the related accounts, and any residual values are charged to expense. Depreciation expense has been calculated using the following estimated useful lives: Buildings and other improvements 10–20 years Leasehold improvements Remaining lease period Office furniture and equipment 5–7 years Computer equipment and software 3–5 years Leases The Company entered into a sale-lease back transaction on September 6, 2017 with respect to certain real property and improvements located in Roseville, MN, whereby the Company sold the land and other improvements to a third party in exchange for approximately $7 million in cash and the Company committed to an initial lease term of twenty years, with four options to extend the term of the Lease Agreement for five years each. The transaction also included a construction contract for the Company’s new nearly 40,000 square-foot corporate headquarters which when complete will include office, research laboratory space and outdoor growing plots. During the construction period, the company will initially pay annual base rent of $490 thousand until the property has been substantially completed, at which time, the lease will commence and the Company will pay annual base rent at the rate of 8% of the total cost which based on the project plan would approximate an annual base rent of $1,480 thousand. The Lease Agreement is a net lease, whereby the Company is responsible for the other costs and expenses associated with the use of the property. Cellectis entered into a Lease Guaranty with the landlord, whereby Cellectis has guaranteed the Company’s obligations under the Lease Agreement. Cellectis’ guarantee of Calyxt’s obligations under the sale-leaseback transaction will terminate at the end of the second consecutive calendar year in which Calyxt’s tangible net worth exceeds $300 million, as determined in accordance with generally accepted accounting principles. The Company is responsible for construction cost over runs. As a result of this involvement, the Company is deemed the “owner” for accounting purposes during the construction period and is required to capitalize the construction costs on the Balance Sheet. The sale of the land and structures also does not qualify for sale-leaseback accounting under ASC 840 as a result of “continuing involvement” and the guarantee of the transaction by Cellectis. Under ASC 840, the “continuing involvement” precludes the Company from derecognizing the assets from the Balance Sheet. When the assets under construction have been substantially completed the assets associated with the project will be capitalized and depreciated over the term of the lease. The Company has recorded assets under construction of $1,374 thousand and a finance obligation of $7,934 thousand as of September 30, 2017. Long-Lived Assets Management 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. If the impairment tests indicate that the carrying value of the asset, or asset group is greater than the expected undiscounted cash flows to be generated by such asset or asset group, further analysis is performed to determine the fair value of the asset or asset group. To the extent the fair value of the asset or asset group is less than its carrying value, an impairment loss is recognized equal to the amount the carrying value exceeds the fair value of the asset or asset group. The Company generally measures fair value by considering sale prices for similar assets or asset groups, or by discounting estimated future cash flows from such assets or asset groups using an appropriate discount rate. Assets to be disposed of are carried at the lower of their carrying value or fair value less costs to sell. There have been no impairment losses recognized for the three and nine months ended September 30, 2017 or September 30, 2016. Fair Value of Financial Instruments Pursuant to the requirements of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 820, Fair Value Measurement Level 1 Level 2 over-the-counter Level 3 The Company has derivative instruments that are classified as Level 2. The Company does not have any financial instruments classified as Level 3, and there were no movements between these categories during the nine months ended September 30, 2017 or September 30, 2016. Forward Purchase Contracts and Derivatives The Company enters into supply agreements for grain and seed production with settlement values based on commodity market futures pricing. The Company accounts for these derivative financial instruments utilizing the authoritative guidance in ASC Topic 815, Derivatives and Hedging Unrealized gains and losses on all derivative contracts are recorded in other current assets or other current liabilities on the balance sheet at fair value. The gains and losses recorded by the Company are not significant for the three and nine months ended September 30, 2017 or 2016. The table below summarizes the carrying value of derivative instruments as of September 30, 2017 and December 31, 2016. Derivatives not Asset Derivatives Liability Derivatives Balance Sheet Location Fair Value Balance Sheet Location Fair Value September 30, December 31, September 30, December 31, (in thousands) (in thousands) (in thousands) (in thousands) Forward purchase contracts Prepaid expenses and $ 3 $ 9 Accrued liabilities—current $ 5 $ 19 Total derivatives $ 3 $ 9 $ 5 $ 19 Patents The Company expenses patent costs, including related legal costs, as incurred and records such costs within selling, general and administrative expenses in the statements of operations. Revenue Recognition The Company enters into R&D agreements that may consist of nonrefundable up-front For agreements that contain multiple elements, each element within a multiple-element arrangement is accounted for as a separate unit of accounting provided the following criteria are met: the delivered products or services have value to the customer on a stand-alone basis and, for an arrangement that includes a general right of return relative to the delivered products or services, delivery, or performance of the undelivered product or service is considered probable and is substantially controlled by the Company. The Company considers a deliverable to have stand-alone value if the product or service is sold separately by the Company or another vendor or could be resold by the customer. Further, the Company’s revenue arrangements do not include a general right of return relative to the delivered products. Nonrefundable up-front Milestone payments represent amounts received from the Company’s R&D partners, the receipt of which is dependent upon the achievement of certain scientific, regulatory, or commercial milestones. The Company recognizes milestone payments when the triggering event has occurred, there are no further contingencies or services to be provided with respect to that event, and the counterparty has no right to refund of the payment. The triggering event may be scientific results achieved by the Company or another party to the arrangement, regulatory approvals, or the marketing of products developed under the arrangement. Royalty revenue arises from the Company’s contractual entitlement to receive a percentage of product sales revenues achieved by counterparties. Royalty revenue is recognized on an accrual basis in accordance with the terms of the agreement when sales can be determined reliably and there is reasonable assurance that the receivables from outstanding royalties will be collected. License revenue from licenses that were granted to third parties is recognized ratably over the period of the license agreements. Revenue from R&D services is recognized over the period the R&D services are performed. Cost of Revenue Cost of revenue relates to the performance of services or contract research and consists of direct external expenses relating to projects and internal costs, including overhead allocated on a full-time equivalent basis. Research and Development R&D expenses represent costs incurred for the development of various products using licensed gene editing technology, including expenses allocated to Calyxt by Cellectis. R&D expenses consist primarily of salaries and related costs of the Company’s scientists, in-licensing In the normal course of business, Calyxt enters into R&D contracts with third parties whereby Calyxt performs R&D of certain gene traits for the third party. The Company has entered into various multiyear arrangements in which Calyxt performs the R&D of the gene technology and the third parties generally have primary responsibility for any commercialization of the technology. These arrangements are performed with no guarantee of either technological or commercial success. The Company in-licenses up-front in-licensing in-licensing in-licensing in-licensing Foreign Currency Transactions Transactions in foreign currencies are remeasured into the Company’s functional currency, U.S. dollars, at the exchange rates effective at the transaction dates. Assets and liabilities denominated in foreign currencies at the reporting date are remeasured into the functional currency using the exchange rate effective at that date. The resulting exchange gains or losses are recorded in the statements of operations under selling, general, and administrative expenses. Income Taxes Current income taxes are recorded based on statutory obligations for the current operating period for the jurisdictions in which the Company has operations. Deferred taxes are provided on an asset and liability method, whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The tax effects from an uncertain tax position can be recognized in the financial statements only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. Calyxt recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit.
