Organization and Summary of Significant Accounting Policies

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Overview

Calyxt, Inc., formerly known as Cellectis Plant Sciences, Inc. was founded in 2010 and incorporated in Delaware. We are headquartered in Roseville, Minnesota. We are a technology company focused on delivering plant-based solutions that are healthy and sustainable. Prior to our initial public offering (IPO) on July 25, 2017, we were a wholly owned subsidiary of Cellectis S.A. (Cellectis). As of December 31, 2020, Cellectis owned 64.7 percent of our outstanding common stock. Certain prior year amounts have been reclassified to conform to current year presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes, including those related to revenue recognition, forward purchase contracts, stock-based compensation, and valuation allowances on deferred tax assets. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

We consider all investments purchased with an original maturity of three months or less to be cash equivalents. Restricted cash, which we hold for the benefit of our counterparty on an equipment lease facility, is also invested in cash equivalents.

Short-term investments

We consider investments with more than ninety days to maturity at issuance to be short-term investments. These short-term investments are considered trading securities and are carried at fair value with any unrealized gains and losses recorded in current earnings as a component of interest, net.

Accounts Receivable

Accounts receivable are unsecured and are recorded at net realizable value. We make judgments as to our ability to collect outstanding receivables based upon patterns of collectability, historical experience, and our evaluation of specific accounts and will provide an allowance for credit losses when collection becomes doubtful. We perform credit evaluations of our customers’ financial condition on an as-needed basis. Payment is generally due fifteen or thirty days from the invoice date depending upon the product, and accounts past 30 days are individually analyzed for collectability. When all collection efforts have been exhausted, the account is written off.

Forward Purchase Contracts

We enter into seed and grain production agreements (Forward Purchase Contracts) with seed producers and growers.

The seed contracts often require us to pay prices for the seed produced at commodity futures market prices plus a premium. The seed growers have the option to fix their price with us throughout the term of the agreement. We pay a portion of the seed cost in December each year and the remainder upon delivery in either the first or second quarter of the following year.

The grain grower contracts require us to pay prices for all grain produced at commodity futures market prices plus a premium. The grain growers have the option to fix their price with us throughout the term of the agreement. The grain grower contracts allow for delivery of grain to us at harvest if so specified when the agreement is executed, otherwise delivery occurs on a date that we elect through August 31 of the following year. We pay for grain within a contractually determined number of days following delivery and final pricing.

In all periods prior to January 1, 2019, we considered Forward Purchase Contracts to be derivatives and recorded the contracts at fair market value with changes in value reflected in earnings as R&D expense. Effective January 1, 2019, we designated all Forward Purchase Contracts as normal purchases and as a result no longer consider these agreements to be derivatives. As of that date, any mark-to-market gains or losses associated with those contracts were fixed and were reflected in inventory, upon our purchase of the underlying grain.

Inventory

Inventories are recorded at the lower of cost or net realizable value and include all costs of seed production and grain we purchase as well as costs to store, transport and process the grain into finished products. Consideration we receive from growers when they purchase seed is recorded as a reduction of inventory.

We evaluate inventory balances for obsolescence on a regular basis based on the age of the inventory and our sales forecasts. At each period-end, we make assumptions regarding projected selling prices for our products considering futures market prices for the underlying agricultural markets and our associated risk management strategies, our anticipated costs, and other factors that take into consideration our limited operating history and compare those prices to the current weighted average costs of our inventories. If our costs are higher than the projected selling prices, then a valuation adjustment is recorded.

Prior to our commercialization of high oleic soybean products, all Grain Costs were expensed as R&D.

Fair Value of Financial Instruments

We record financial instruments at fair value with changes in those values reported in our results of operations each period. We determine values using readily available market prices, instruments with similar terms and underlying inputs that are quoted on exchanges, or other valuation techniques if no observable inputs are available.

Land, Buildings, and Equipment

Land, buildings, and equipment are stated at cost less accumulated depreciation. Assets under capital lease are stated at the lesser of their net present value of future lease payments or fair market value. 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		15 years
Office furniture and equipment		7 years
Assets under capital lease		4-20 years
Computer equipment and software		3-5 years
Vehicles		3-6 years

We review our 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. Assets to be disposed of are carried at the lower of their carrying value or fair value less costs to sell. Fair value is measured using a discounted cash flow model or independent appraisals, as appropriate. We have not recognized any impairment losses in these consolidated financial statements.

Revenue Recognition – Product Sales

We recognize sales revenue at the point in time that title transfers to the customer, which is based on shipping terms. Sales include shipping and handling charges if billed to the customer and are reported net of trade promotion and other costs, including estimated allowances for returns, unsalable product, and prompt pay discounts. Sales, use, value-added and other excise taxes are not recognized in revenue. Trade promotions are recorded based on estimated participation and performance levels for offered programs at the time of sale. We generally do not allow a right of return.

In certain instances, we may sell grain to a processor with a commitment to repurchase any soybean meal resulting from their grain crushing activity with a single net cash settlement occurring between the parties. In those instances, we recognize revenue from the sale of grain in the amount of the final net cash settlement with the processor. We also recognize revenue on our sale of the meal to our customers in accordance with our previously disclosed revenue recognition accounting policies. Costs are ascribed to grain and meal sold pursuant to the agreement with the processor.

In certain instances, we may sell grain to a processor and subsequent to the sale they will utilize our storage facility to hold the grain until such time they request it be delivered. We are responsible for all handling charges and delivery activities. In those instances, we recognize revenue from the sale of grain to the processor upon the transfer of the control of the grain through the assignment of warehouse receipts, and concurrently accrue all estimated future storage, handling, and delivery costs associated with that sale.

Revenue Recognition – Out-licensing of Technology

We recognize revenue from license agreements, which may consist of nonrefundable up-front payments, milestone payments, annual payments, royalties, and services.

Nonrefundable up-front payments are deferred and recognized as revenue over the term of the license agreement. If a license agreement is terminated before the original term of the agreement is fulfilled, all remaining deferred revenue is recognized at termination.

Milestone payments represent amounts received from our licensees, the receipt of which is dependent upon the achievement of certain scientific, regulatory, or commercial milestones. We recognize 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.

Advertising Costs

We expense advertising costs as incurred.

Research and Development (R&D)

We recognize R&D expenses as incurred. These expenses consist of direct costs for R&D and R&D-related allocations of overhead costs such as facilities and information technology costs. Costs incurred in connection with collaborator-funded activities are expensed as incurred. Costs to acquire technologies that are utilized in R&D that have no alternative future use are expensed as incurred. Prior to the commercialization of a product, Grain Costs are expensed as R&D.

Patents

We expense patent costs, including related legal costs, as incurred. Costs to write and support the research for filing patents are recorded as R&D expenses in the statements of operations. Costs to maintain, in-license, and defend patents are recorded as G&A expenses in the statements of operations.

Stock-Based Compensation

We generally measure employee and nonemployee stock-based awards at grant-date fair value and record compensation expense over the vesting period of the award. Prior to our adoption of new accounting rules on January 1, 2019, stock-based awards issued to nonemployees were remeasured until the award vests. We use the Black-Scholes option pricing model to value our stock option awards.

The expected term of stock options is estimated using the average of the vesting tranches and the contractual life of each grant for employee options as we have limited historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for our stock option grants. For options granted to nonemployees, we use the remaining

contractual life. For stock price volatility, we use comparable public companies as a basis for our expected volatility. The risk-free interest rate is based on United States Treasury notes with a term approximating the expected term of the option. We assume no dividend yield because dividends are not expected to be paid.

We generally measure compensation expense for grants of restricted stock units using the value of a share of our stock on the date of grant. Prior to our adoption of new accounting rules on January 1, 2019, compensation expense for grants of stock awards to nonemployees were initially measured using the share price on date of grant and remeasured quarterly.

If an award is forfeited prior to vesting the associated reduction in expense is reflected net in stock-based compensation expense in that period. Stock-based compensation expense is recorded in R&D, S&SC, or G&A expenses in our consolidated statements of operations.

Income Taxes

Current income taxes are recorded based on statutory obligations for the current operating period for the jurisdictions in which we have 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 we believe it is more likely than not that some portion or all 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.

Foreign Currency Transactions

Transactions in foreign currencies are translated at the exchange rates effective on the transaction dates. Assets and liabilities denominated in foreign currencies are translated at the period-end exchange rate. Foreign currency gains and losses are recognized in non-operating expenses in the consolidated statements of operations.

Financial Instruments, Fair Value, and Concentrations of Credit Risk

2. FINANCIAL INSTRUMENTS, FAIR VALUE, AND CONCENTRATIONS OF CREDIT RISK

Financial instruments including cash and cash equivalents, restricted cash, accounts payable, due to related parties and all other current liabilities have carrying values that approximate fair value. We measure short-term investments and commodity derivative contracts at fair value on a recurring basis. The accounting guidance establishes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as of the measurement date as follows:

Level 1: Fair values are based on unadjusted quoted prices in active trading markets for identical assets and liabilities.

Level 2: Fair values are based on observable quoted prices other than those in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.

Level 3: Fair values are based on at least one significant unobservable input for the asset or liability.

Fair Value Measurements and Financial Statement Presentation

The fair values of our assets, liabilities, and derivative positions recorded at fair value and their respective levels in the fair value hierarchy as of December 31, 2020 and December 31, 2019, were as follows:

The non-current portion of our financing lease obligations are also considered a financial instrument, which we measure at fair value for disclosure purposes. It is a Level 2 liability and had a fair value of $15.2 million as of December 31, 2020, and a fair value of $15.7 million as of December 31, 2019.

The composition of our short-term investments as of December 31, 2020, and December 31, 2019 were as follows:

	As of December 31,

Commodity Price Risk

We enter into seed and grain production agreements with settlement values based on commodity futures market prices. These Forward Purchase Contracts allow the counterparty to fix their sales prices at various times as defined in the contract. Because we intend to take physical delivery under the Forward Purchase Contracts, we have grain inventory we will need to sell. We intend to sell these inventories at then-current market prices. As a result, when the Forward Purchase Contract counterparty fixes their grain prices, we enter hedging arrangements by selling futures contracts which converts our exposure to these fixed prices to floating prices. We expect to maintain these hedging relationships until such grain inventory is sold to help stabilize our margins. We do not account for these economic hedges as accounting hedges. We expect any gains or losses from these hedging arrangements to be offset by gains or losses on the grain inventories when such grain inventories are sold. As of December 31, 2020, we have $2.0 million of unrealized commodity derivative losses from hedging contracts sold to convert our fixed price grain inventories and fixed price Forward Purchase Contracts to floating prices. As of December 31, 2020, we held commodity contracts with a notional amount of $12.8 million.

We previously designated all our commodity derivative contracts as cash flow hedges based on the nature of our business activities under the prior go-to-market strategy. As a result, all gains or losses associated with recording those commodity derivative contracts at fair value were recorded as a component of accumulated other comprehensive income (loss) (AOCI). We reclassify amounts from AOCI to cost of goods sold when we sell the underlying products to which those hedges relate.

Certain amounts related to our hedging activities are as follows:

	Amount of Gain (Loss)				Amount of Gain (Loss) Reclassified to Earnings
	Recognized in AOCI				Year ended
	December 31,				December 31,
In thousands	2020		2019		2020		2019			2018
Cash flow hedges:
Commodity contracts	$	—	$	17	$	17	$	(81	)	$	—
Total	$	—	$	17	$	17	$	(81	)	$	—

Foreign Exchange Risk

Foreign currency fluctuations affect our foreign currency cash flows related primarily to payments to Cellectis. Our principal foreign currency exposure is to the Euro. We do not hedge these exposures, and we do not believe that the current level of foreign currency risk is significant to our operations.

Concentrations of Credit Risk

We invest our cash, cash equivalents and restricted cash in highly liquid securities and investment funds and until late December 2019, also held deposits at a financial institution that exceeded insured limits. In the first quarter of 2020, we diversified this risk by shifting our investments to a diverse portfolio of short-dated, high investment-grade securities we classify as short-term investments that are recorded at fair value in our consolidated financial statements. We ensure the credit risk in this portfolio is in accordance with our internal policies and if necessary, make changes to investments to ensure credit risk is minimized. We have not experienced any counterparty credit losses.

Related-Party Transactions

3. RELATED-PARTY TRANSACTIONS

We have several agreements that govern our relationship with Cellectis, some of which require us to make payments to Cellectis. Pursuant to our management services agreement with Cellectis, we incurred management fee expenses of $0.3 million in 2020, $1.3 million in 2019, and $2.3 million in 2018.

Cellectis has also guaranteed the lease agreement for our headquarters. Cellectis’ guarantee of our obligations under the lease will terminate at the end of the second consecutive calendar year in which our tangible net worth exceeds $300 million.

During the year ended December 31, 2020, Cellectis purchased 1,250,000 shares of common stock in our follow-on offering at the public offering price of $4.00 per share. During the year ended December 31, 2018, Cellectis purchased 550,000 shares of common stock in our follow-on offering at the public offering price of $15.00 per share. In addition, in connection with the vesting on June 14, 2018, of restricted stock units for certain of our and Cellectis’ employees and nonemployees, Cellectis purchased 63,175 shares of our common stock at a price of $19.49 per share (the closing price reported on the NASDAQ Global Market on June 14, 2018) directly from such employees and nonemployees in private transactions pursuant to share purchase agreements dated June 13, 2018.

TALEN is our primary gene editing technology, and it is the foundation of our technology platform. TALEN technology was invented by researchers at the University of Minnesota and Iowa State University and exclusively licensed to Cellectis. We obtained an exclusive license for the TALEN technology for commercial use in plants from Cellectis. We also license other technology from Cellectis. We owe Cellectis royalties on any revenue we generate from sales of products less certain amounts as defined in the license agreement, as well as a percentage of any sublicense revenues. We have incurred $0.2 million of license and royalty fees for the year ended December 31, 2020, $0.3 million for the year ended December 31, 2019 and nominal license and royalty fees for the year ended December 31, 2018.

We have entered into various agreements with the University of Minnesota, pursuant to which we have been granted both exclusive and non-exclusive license agreements that carry annual license fees, milestone payments, royalties, and associated legal fees. These agreements primarily relate to gene editing tools, enabling technologies and germplasm. We incurred nominal expenses pursuant to these agreements for the years ended December 31, 2020, 2019, and 2018.

Stock-Based Compensation

6. STOCK-BASED COMPENSATION

We use broad-based stock plans to attract and retain highly qualified officers and employees and to help ensure that management’s interests are aligned with those of our shareholders. We have also granted equity-based awards to directors, nonemployees, and certain employees of Cellectis.

In December 2014, we adopted the Calyxt, Inc. Equity Incentive Plan (2014 Plan), which allowed for the grant of stock options, and in June 2017, we adopted the 2017 Omnibus Plan (2017 Plan), which allowed for the grant of stock options, restricted stock, restricted units, performance shares, and other types of equity awards.

As of December 31, 2020, 1,784,478 shares were registered and available for grant under approved registration statements, while 3,938,285 shares were available for grant in the form of stock options, restricted stock, restricted stock units and performance stock units under the 2017 Plan. Stock-based awards currently outstanding also include some granted under the 2014 Plan, under which no further awards will be granted.

Stock Options

The estimated fair values of stock options granted, and the assumptions used for the Black-Scholes option pricing model were as follows:

	Year ended December 31,
	2020		2019		2018
Estimated fair values of stock options granted	$	3.24	$	10.18	$	9.09
Assumptions:
Risk-free interest rate	.3% - 1.7%		1.7% - 2.5%		2.2% - 3.0%
Expected volatility	77.4% - 81.2%		52.6% - 78.9%		40.9% - 57.2%
Expected term (in years)	6.0 - 10		6.8 - 10		5.6 - 10

We estimate the fair value of each option on the grant date, or other measurement dates if applicable, using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding employee exercise behavior, future stock price volatility, and dividend yield. Our expected term represents the period that options granted are expected to be outstanding determined using the simplified method. We estimate our future stock price volatility using the historical volatility of comparable public companies over the expected term of the option. We estimate the risk-free interest rate based on the United States Treasury zero-coupon yield curve at the date of grant for the expected term of the option. We do not nor do we expect to pay dividends.

Options may be priced at 100 percent or more of the fair market value on the date of grant and generally vest over three to six years after the date of grant. Options generally expire within 10 years after the date of grant.

Information on stock option activity is as follows:

	Options Exercisable		Weighted- Average Exercise Price Per Share		Options Outstanding			Weighted- Average Exercise Price Per Share

Stock-based compensation expense related to stock option awards was as follows:

	Year ended December 31,
In Thousands	2020		2019		2018
Stock-based compensation expenses	$	3,371	$	6,035	$	3,609

The aggregate intrinsic value of options exercisable at December 31, 2020 was $0.6 million and the weighted average remaining contractual term was 6.2 years as of that date.

Net cash proceeds from the exercise of stock options less shares used for minimum withholding taxes and the intrinsic value of options exercised were as follows:

	Year ended December 31,
In Thousands	2020		2019		2018
Net cash proceeds	$	212	$	344	$	2,622
Intrinsic value of options exercised	$	179	$	905	$	7,569

As of December 31, 2020, unrecognized compensation expense related to non-vested stock options was $7.7 million. This expense will be recognized over 30 months on average.

Restricted Stock Units

Units settled in stock subject to a restricted period may be granted to key employees under the 2017 Plan. Restricted stock units generally vest and become unrestricted over three to five years after the date of grant.

Information on restricted stock unit activity follows:

	Number of Restricted Stock Units Outstanding			Weighted- Average Grant Date Fair Value
Unvested balance at December 31, 2019		813,526		$	10.31

	Year ended December 31,
In Thousands	2020		2019		2018
Grant-date fair value	$	3,122	$	3,141	$	2,691

Information on the weighted average grant date fair value of restricted stock units issued was as follows:

As of December 31, 2020, unrecognized compensation expense related to restricted stock units was $2.0 million. This expense will be recognized over 25 months on average.

We treat stock-based compensation awards granted to employees of Cellectis as deemed dividends. We recorded deemed dividends for restricted stock units as follows:

	Year ended December 31,
In Thousands	2020		2019		2018
Deemed dividends from grants to Cellectis employees	$	1,168	$	1,358	$	2,253

Performance Stock Units

In June 2019, we granted 311,667 performance stock units under the 2017 Plan to three executive officers. The performance stock units will vest at 50 percent, 100 percent, or 120 percent of the shares under the award at the end of a three-year performance period based upon increases in the value of our common stock from the grant price of $12.48. The performance stock units will be settled in restricted stock upon vesting, with restrictions on transfer lapsing on the second anniversary of the restricted stock issuance date.

The estimated fair values of performance stock units granted, and the assumptions used for the Monte Carlo simulation pricing model were as follows:

Estimated fair values of performance stock units granted	$	7.06
Assumptions:
Risk-free interest rate		1.71	%
Expected volatility		75.0	%
Expected term (in years)	3.0

	Year ended December 31,
In Thousands	2020		2019
Stock-based compensation expenses	$	445	$	225

As of December 31, 2020, unrecognized compensation expense related to performance stock units was $1.5 million and will be recognized over 42 months.

Cellectis Equity Incentive Plan

Prior to 2018, Cellectis granted stock options to our employees. Compensation costs related to these grants have been recognized in the statements of operations with a corresponding credit to stockholders’ equity, representing the Cellectis’ capital contribution to us. The fair value of each stock option was estimated at the grant date using the Black-Scholes option pricing model.

We recognized stock-based compensation expense related to our Cellectis’ grants of $0.1 million in 2018. Expenses in 2019 were immaterial and as of December 31, 2019, all expenses related to these awards had been recognized.

Net deferred tax asset or liability	$	—		$	—		$	—

We provide for a valuation allowance when it is more likely than not that we will not realize a portion of the deferred tax assets. We have established a full valuation allowance for deferred tax assets described above due to the uncertainty that enough taxable income will be generated in the taxing jurisdiction to utilize the assets. Therefore, we have not reflected any benefit of such deferred tax assets in the accompanying consolidated financial statements

We have $206.1 million of tax loss carryforwards. Of this amount, $64.0 million are state operating loss carryforwards and $142.1 million are federal operating loss carryforwards. The federal carryforward periods are as follows: $100.2 million do not expire and $41.9 million expire between 2032 and 2037. The state net operating losses will expire between 2027 and 2037, with some amounts having indefinite carryover. We also have federal and state R&D credit carryovers of $1.9 million and $0.9 million, which will expire between 2032 and 2037.

We are subject to federal income taxes in the United States as well as various state and local jurisdictions. Several years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the outcome or the timing of resolution of any uncertain tax position, we do not believe that we need to recognize any liabilities for uncertain tax positions as of December 31, 2020. We will classify any future interest and penalties as a component of income tax expense if incurred.

We do not expect the amount of uncertain tax positions to change significantly in the next twelve months. Our major taxing jurisdictions are in the United States, at both the federal and state levels. The number of years open for examination varies depending on the tax jurisdiction, but are generally from 3 to 5 years.

Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Leases, Other Commitments, and Contingencies

8. LEASES, OTHER COMMITMENTS, AND CONTINGENCIES

Litigation and Claims

We are not currently a party to any material pending legal proceeding.

Leases

We lease our headquarters facility, office equipment, and other items. Our headquarters lease involved the sale of land and improvements to a third party who then constructed the facility. This lease is considered a financing lease.

Sale-Leaseback of Headquarters and Lab Facility

Our headquarters facility is comprised of a 40,000 square-foot office and lab building, greenhouses, and outdoor research plots. We are deemed the owner for accounting purposes. The lease has a term of twenty years with four options to extend its term for five years each subject to there being no default under the lease terms beyond any cure period and us occupying the property at the time of extension. In 2017, we received $7.0 million in connection with the sale of the land and uncompleted facility.

The lease commenced in May 2018. Under the lease, we pay an annual base rent of eight percent of the total project cost with scheduled increases in rent of 7.5 percent on the sixth, eleventh and sixteenth anniversaries of the start of the lease commencement as well as on the first day of each renewal term. Currently, we pay an annual base rent of $1.4 million.

We are also responsible for all operating costs and expenses associated with the property. Beginning on the eighteenth month anniversary of the start of the lease, if the landlord decides to sell the property, we have a right of first refusal to purchase the property on the same terms offered to any third party.

Concurrent with entering the lease, Cellectis guaranteed all our obligations under the lease agreement. Cellectis’ guarantee of our obligations will terminate at the end of the second consecutive calendar year in which our tangible net worth exceeds $300 million, as determined in accordance with generally accepted accounting principles. At a point when Cellectis owns 50 percent or less of our outstanding common stock, we have agreed to indemnify Cellectis for any obligations incurred by Cellectis under its guaranty of our obligations under the lease.

Sale-Leaseback of Equipment

We also have an equipment financing arrangement that is considered a financing lease. This arrangement had a term of four years for each draw. We were required to deposit cash into a restricted account in an amount equal to the future rent payments required by the lease. As of December 31, 2020, this restricted cash totaled $1.0 million. We have the option to request the return of excess collateral annually in December, and the amount we expect to receive is reflected as a current asset. The equipment financing arrangement allows for a six-month renewal option or a repurchase option at the end of the lease term.

Operating Leases

As a lessee, we lease office equipment, storage facilities and vehicles under various operating leases.

Rent expense from all operating leases was as follows:

Other Commitments

As of December 31, 2020, we have noncancelable commitments to purchase grain from farmers and seed from growers at dates throughout 2021 aggregating $21.2 million based on current commodity futures market prices, other payments to growers and estimated yields per acre. This amount is not recorded in the consolidated financial statements because we have not taken delivery of the grain or seed as of December 31, 2020.

We carry receivables related to amounts we are owed by growers from their purchases of seed. These amounts reduce the cost of the grain we ultimately purchase from the grower and are repaid either on current terms or on an extended payment basis. If a grower has elected an extended payment term, they will pay a higher price per unit and grant us the right to deduct the amount we are owed from the payment we make upon the purchase of their grain. As of December 31, 2020, $0.6 million of the receivables from growers were on extended payment terms. As of December 31, 2019, this amount was zero.

Debt Disclosure [Abstract]

Long-Term Debt

12. LONG-TERM DEBT

Our long-term debt is comprised of a $1.5 million promissory note pursuant to the Paycheck Protection Program (the Paycheck Protection Program loan) established by the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) implemented by the U.S. Small Business Administration (SBA). We received the funds under the Paycheck Protection Program loan on April 19, 2020. The Paycheck Protection Program loan matures in April 2022 and bears interest at a per annum rate of one percent. The Paycheck Protection Program loan may be prepaid at any time prior to maturity with no prepayment penalties. The Paycheck Protection Program loan contains customary events of default relating to, among other things, payment defaults and breaches of representations and warranties. Subject to certain conditions, the Paycheck Protection Program loan and accrued interest may be forgiven in whole or in part by applying for forgiveness pursuant to the CARES Act and the Paycheck Protection Program. In order to be eligible for forgiveness, the proceeds of the Paycheck Protection Program loan must be applied to certain eligible expenses, including payroll costs, interest on certain mortgage obligations, rent payments on certain leases, and certain qualified utility payments, with not more than 40 percent of the amount applied to non-payroll costs.

We have applied the proceeds from the Paycheck Protection Program loan toward qualifying expenses and on October 21, 2020, as modified December 29, 2020, applied for forgiveness of the full principal amount and all accrued interest. No assurance can be given that we will be granted forgiveness of the Paycheck Protection Program loan in whole or in part.

Restructuring Costs

13. RESTRUCTURING COSTS

On August 4, 2020, we approved the advancement of our soybean products to a streamlined go-to-market strategy. The impact of the advancement included staffing adjustments related to soybean processing and product sales, as well as the gradual exit of all supply chain contractual commitments that are not associated with the ongoing soybean seed go-to-market strategy. In the twelve months ended December 31, 2020, we recorded $0.7 million of restructuring costs for severance and other related payments, and we also recorded a $0.9 million recapture benefit of non-cash stock compensation expense from the forfeiture or modification of unvested stock awards. We have not incurred any other material costs from the disposal of any assets or contractual terminations as of December 31, 2020. Contracted grain purchases, subsequent sales of grain, and the wind down of other contractual obligations are on-track to be completed in late 2021.

The following table presents the employee separation liabilities as of December 31, 2020:

	As of December 31,
In Thousands	2020
Balance as of December 31, 2019	$	—
Charged to expense		685
Cash payments		(265	)
Balance as of December 31, 2020	$	420

The December 31, 2020, liability of $0.4 million is expected to be paid through the second quarter of fiscal 2021.

14. SUBSEQUENT EVENTS

On February 19, 2021 Yves Ribeill, Ph.D., Chair of the Board of Directors of Calyxt, Inc., was appointed as the Executive Chair of the Board of Directors and in that capacity, will serve as Calyxt’s principal executive officer until the appointment of a successor to James Blome, our former Chief Executive Officer. Mr. Blome is entitled to compensation and benefits as part of this termination without cause, and in the first quarter of 2021, we expect to record up to $2.3 million of cash expense for separation-related payments as well as an additional non-cash charge of $0.1 million from the acceleration of expense recognition of sign-on bonus paid to Mr. Blome in a prior period. The cash payments to Mr. Blome will be made over a period of 24 months from the date his separation agreement is executed. As of the date of this Annual Report that has not occurred, however, we expect it to be completed within its required execution period, which is by March 12, 2021. We also expect to record a benefit to earnings from a $2.5 million recapture of non-cash stock compensation expense from forfeitures of Mr. Blome’s unvested stock awards.
