Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	VUZIX CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1 — Summary of Significant Accounting Policies Operations Vuzix Corporation (the Company) was formed in 1997 under the laws of the State of Delaware and maintains its corporate offices in West Henrietta, New York (a suburb of Rochester). We are engaged in the design, manufacture, marketing and sale of augmented reality wearable display and computing devices also referred to as head mounted displays (or HMDs, but also known as near-eye displays), in the form of Smart Glasses and Augmented Reality (AR) glasses. Our AR wearable display devices are worn like eyeglasses or attach to a head worn mount. These devices typically include cameras, sensors, and a computer that enable the user to view, record and interact with video and digital content, such as computer data, the Internet, social media or entertainment applications. Our wearable display products integrate micro-display technology with our advanced optics to produce compact high-resolution display engines, less than half an inch diagonally, which when viewed through our smart glasses products create virtual images that appear comparable in size to that of a computer monitor or a large-screen television. The wearable display products we produce can be used for a variety of enterprise, commercial and medical uses and applications, including AR for on-the-go users and as mobile displays and remote service support. Our products are available with varying features and are offered as monocular and binocular display systems. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned UK subsidiary, Vuzix (Europe) Limited. All significant inter-company transactions have been eliminated. Segment Data, Geographic Information and Significant Customers The Company is not organized by market and is managed and operated as one business. A single management team that reports to the chief operating decision maker comprehensively manages the entire business. The Company does not operate any material separate lines of business or separate business entities. Accordingly, the Company does not accumulate discrete information, other than product revenue and material costs, with respect to separate product lines and does not have separately reportable segments as defined by FASB ASC Topic 280, “Disclosures about Segments of an Enterprise and Related Information”. Refer to Note 19 — Geographic and Other Financial Information (Unaudited). Foreign Currency Transactions The Company considers the US dollar as the functional currency of the Company’s UK Subsidiary. The Company’s UK Subsidiary transacts in Euros and British pounds. All transactions in foreign currencies are recorded in US dollars at the then current exchange rate(s). Upon settlement of the underlying transaction, all amounts are re-measured to US dollars at the current exchange rate on date of settlement. All unsettled foreign currency transactions that remain in accounts receivable and trade account payables are re-measured to US dollars at the period end exchange rates. All re-measurement gains and losses are recorded in the current period net income. Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at year-end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Concentration of Credit Risk The Company maintains its cash in bank deposit accounts, which at times may exceed federally insured limits. Cash and Cash Equivalents Cash and cash equivalents can include highly liquid investments with original maturities of three months or less. Fair Value of Financial Instruments The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, notes receivable, accounts payable, unearned revenue, accrued expenses, and income taxes payable. As of the consolidated balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented due to the short maturities of these instruments. Accounts Receivable The Company carries its trade accounts receivable at the invoice amount less an allowance for doubtful accounts. The Company establishes an allowance for uncollectible trade accounts receivable based on the age of outstanding invoices and management’s evaluation of collectability of outstanding balances. These provisions are established when the aging of outstanding amounts exceeds allowable terms and are re-evaluated at each quarter end for adequacy. In determining the adequacy of the provision, the Company considers known uncollectible or at-risk receivables. The allowance for doubtful accounts as of December 31, 2021, 2020 and 2019 was nil. The Company does not accrue interest on any past due accounts receivable unless such receivable goes into collection. Customer and Supplier Concentrations One customer represented 10% of total product revenue and four customers represented 39%, 28%, 16% and 12%, respectively, of our engineering services revenue for the year ended December 31, 2021. No one customer represented more than 10% of total product revenue and two customers represented 48% and 26%, respectively, of our engineering services revenue for the year ended December 31, 2020. One customer represented 16% of total product revenue and one customer represented 100% of engineering services revenue for the year ended December 31, 2019 Three customers represented 27%, 20% and 10%, respectively, of accounts receivable at December 31, 2021. Two customers represented 21% and 14%, respectively, of accounts receivable at December 31, 2020. Three customers represented 32%, 26% and 13%, respectively, of accounts receivable at December 31, 2019. Two third-party vendors represented 38% and 24%, respectively, of material purchases for the year ended December 31, 2021. As of December 31, 2021, the net amount due to these vendors was $504,073. Accrued Project Revenue The Company carries accrued project revenue based on the percentage of completion on the project measured using the input method based upon costs incurred to-date as a percentage of total expected costs to complete the project less amounts invoiced, if any. As of December 31, 2021, 2020 and 2019, we had nil in accrued project revenue. Inventories Inventories are valued at the lower of cost or net realizable value using the weighted average first-in, first-out method. The Company includes labor and overhead costs in its inventory valuation costing. The Company records provisions for excess, obsolete or slow-moving inventory based on changes in customer demand, technology developments or other economic factors. The Company’s products have product life cycles that range on average from two to three years currently. At both the product introduction and product discontinuation stage, there is a higher degree of risk of inventory obsolescence. The provision for obsolete and excess inventory is evaluated for adequacy at each quarter end. The estimate of the provision for obsolete and excess inventory is partially based on expected future product sales, which are difficult to forecast for certain products. Revenue Recognition The Company adopted the new guidance on Revenue from Contracts with Customers under FASB ASC Topic 606, "Revenue from Contracts with Customers", as of January 1, 2018. Product sales represent the majority of the Company’s revenue. The Company recognizes revenue from these product sales as performance obligations are satisfied and transfer of control and ownership to the customer has occurred, typically upon physical shipment. Revenue is recognized in the amount that the Company expects to receive in exchange from the sale of our products. FOB shipping point is our standard shipping term and revenue is recognized as our products ship to customers, as control and ownership are transferred at this point in time. All of our standard product sales include a 30-day money back guarantee and expected returns are estimated at each reporting period date and a portion of revenue is deferred for all estimated returns. As of December 31, 2021 and 2020, deferred revenue associated with our expected returns were immaterial. The Company collects and remits sales taxes in certain jurisdictions and reports revenue net of any associated sales taxes. Revenue from any engineering consulting and other services is recognized at the time the services are rendered. The Company accounts for its longer-term development contracts, which to date have all been firm fixed-priced contracts, on the percentage-of-completion method, whereby income is recognized as work on contracts progresses, but estimated losses on contracts in progress are charged to operations immediately. The percentage-of-completion is determined using the cost-to-cost method. To date, all such contracts have been less than one calendar year in duration. Unearned Revenue These amounts represent deferred revenue against our expected product sales returns for all December 2021 products sales that are subject to the Company’s 30-day money back guarantee return policy. Cost of Product Sales Cost of product sales includes the direct and allocated indirect costs of products sold to customers. Direct costs include labor, materials, reserves for estimated warranty expenses, and other costs incurred directly, or charged to us by our contract manufacturers in the manufacture of these products. Indirect costs include labor, manufacturing overhead, and other costs associated with operating our manufacturing facility and capacity. Manufacturing overhead includes the costs of procuring, inspecting and storing material, facility and other costs, and is allocated to cost of product revenue based on the proportion of indirect labor which supported production activities. Depreciation on manufacturing tools and equipment is included in Operating Expenses in our consolidated statement of operations. The cost of product sales can fluctuate significantly from period to period, depending on the product mix and volume, the level of manufacturing overhead expense and the volume of direct cost of materials. Cost of Engineering Services Sales Cost of engineering services revenues includes both the direct and allocated indirect costs of performing on contracts and producing prototype units. Direct costs include labor, materials and other costs incurred directly in performing under the contract. Direct costs also include labor and other costs associated with operating our research and development department based on the level of effort supporting the development activity. Cost of engineering sales is determined by the level of direct and indirect costs incurred, which can fluctuate substantially from period to period. Fixed Assets Fixed assets are stated at cost. Depreciation of fixed assets is provided for using the straight-line method over the following estimated useful lives: ​ ​ ​ ​ Computers and Purchased Software 3 years Leasehold Improvements Lesser of expected life or lease term Manufacturing Equipment 5 years Tooling 3 years Furniture and Equipment 5 years ​ Repairs and maintenance costs are expensed as incurred. Asset betterments are capitalized and depreciated over their expected useful life. Patents and Trademarks The Company capitalizes the costs of obtaining its patents and registration of trademarks. Such costs are accumulated and capitalized during the filing periods, which can take several years to complete. Successful applications that result in the granting of a patent or trademark are then amortized over 15 years on a straight-line basis. Unsuccessful applications are written off and expensed in the fiscal period where the application is abandoned or discontinued. Ongoing maintenance and legal fees for issued patents and trademarks are expensed as incurred. Software Development Costs The Company capitalizes the costs of obtaining or developing its software once technological feasibility has been determined by management or of purchased software solutions when placed into service. Such costs are accumulated and capitalized. Projects can take several years to complete. Unsuccessful or discontinued software projects are written off and expensed in the fiscal period when the software development effort is abandoned or discontinued. Costs incurred internally in researching and developing a computer software product are charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs are capitalized until the product is available for general release to customers. Judgment is required in determining when technological feasibility of a product is established. Once the product is available for general release, accumulated costs are amortized over the life of the asset. The amortization of these costs is included in cost of product sales over the estimated life of the products, which currently is estimated as three years using a straight-line basis. As of December 31, 2021, 2020 and 2019, we had $541,666, $458,333 and $100,000, respectively, of net software development costs included in Other Assets. For the years ended December 31, 2021, 2020 and 2019, there was nil in impairment of software development costs. Licenses The Company capitalizes the costs of acquiring licenses and prepaid royalties. They are amortized on either a per unit basis or straight line over the life of the license. In some cases, future royalties are subject to annual limits. Long-Lived Assets The Company at least annually assesses all of its long-lived assets for impairment and when events or circumstances indicate their carrying amounts may not be recoverable, in accordance with FASB ASC Topic 360-10, “Accounting for the Impairment or Disposal of Long-Lived Assets.” For the years ended December 31, 2021 and 2020, there was an impairment charge of $80,163 and $73,532, respectively, to Patents and Trademarks and nil in 2019. For the year ended December 31, 2021, we recorded a loss on fixed asset disposal of $183,614 upon the retirement of certain tooling and manufacturing equipment assets no longer in use. No loss on fixed asset disposal charges on tooling and equipment were recorded in 2020 or 2019. Research and Development Research and development costs are expensed as incurred consistent with the guidance of FASB ASC Topic 730, “Research and Development,” and include employee related costs, office expenses, third-party design and engineering services, and new product prototyping costs. Costs incurred internally in researching and developing a computer software product are charged to expense until technological feasibility has been established for the product. Shipping and Handling Costs Amounts charged to customers and costs incurred by the Company related to shipping and handling are included in net sales and cost of sales, respectively. Provision for Future Warranty Costs The Company provides for the estimated returns under warranty and the costs of fulfilling our obligations under product warranties at the time the related revenue is recognized. The Company estimates the costs based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific warranty terms and conditions vary depending upon the country in which we do business, but generally include parts and labor over a period generally ranging from one to two years from the date of product shipment. The Company provides a reserve for expected future warranty returns at the time of product shipment or produces over-builds to cover replacements. We regularly reevaluate our estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary each quarter end, based upon historical experience of warranty claims and costs. Advertising Advertising costs are expensed as incurred and recorded in “Selling and Marketing” in the Consolidated Statements of Operations. Advertising expense for the years ended December 31, 2021, 2020 and 2019 was $1,263,897, $974,461 and $1,302,120, respectively. Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740-10, “Income Taxes.” Accordingly, the Company provides deferred income tax assets and liabilities based on the estimated future tax effects of differences between the financial and tax bases of assets and liabilities based on currently enacted tax laws. A valuation allowance is established for deferred tax assets in amounts for which realization is not considered more likely than not to occur. The Company reports any interest and penalties accrued relating to uncertain income tax positions as a component of the income tax provision. Net Loss Per Share Basic earnings per share is computed by dividing the net income (loss) less accrued dividends on any outstanding preferred stock by the weighted average number of common shares outstanding for the period. Diluted earnings per share calculations reflect the assumed exercise of all dilutive employee stock options and warrants applying the treasury stock method promulgated by FASB ASC Topic 260, “Earnings Per Share” and the conversion of any outstanding convertible preferred shares or notes payable that are-in-the-money, applying the as-if-converted method. However, if the assumed exercise of stock options and warrants and the conversion of any preferred shares or convertible notes payable are anti-dilutive, basic and diluted earnings per share are the same for all periods. As a result of the net losses generated in 2021, 2020 and 2019, all outstanding instruments would be antidilutive. As of December 31, 2021, 2020 and 2019, there were 8,606,062, 14,872,703 and 12,858,707 common stock share equivalents, respectively, that were potentially issuable under stock options, conversion of preferred shares (excluding accrued dividends), and stock warrants that could potentially dilute basic earnings per share in the future. Stock-Based Compensation Expense The Company accounts for stock-based compensation to employees and directors in accordance with FASB ASC Topic 718 “Compensation - Stock Compensation,” which requires that compensation expense be recognized in the consolidated financial statements for stock-based awards based on the grant date fair value. For stock option awards, the Black-Scholes-Merton option pricing model was used to estimate the fair value of share-based awards under FASB ASC Topic 718. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and share price volatility. The expected term of options granted was estimated to be the average of the vesting term, historical exercise and forfeiture rates, and the contractual life of the option. The share price volatility at the grant date is estimated using historical stock prices based upon the expected term of the options granted. The risk-free interest rate assumption is determined using the rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. For common stock awards, the Company uses the fair market value of our common stock on the date of each stock-based award based on the market price of the Company’s common shares and the expense related to these awards is recognized over the requisite service period of the awards on a straight-line or graded vesting basis, which is generally commensurate with the vesting term. Stock-based compensation expense associated with stock awards and stock option grants for the years ended December 31, 2021, 2020 and 2019 was $4,047,444, $2,805,842 and $1,498,357, respectively, excluding awards under the Company’s Long-term Incentive Plan (LTIP). The Company issues new shares upon stock option exercises. For stock options awarded under the Company's LTIP, options vest only upon the achievement of certain equity market conditions or performance-based milestones. The fair value of options granted under this program were calculated by using a Monte Carlo simulation for the equity market condition tranches and the Black-Scholes-Merton option pricing method on the performance-based tranches. Stock-based compensation expense associated with the Company's LTIP for the year ended December 31, 2021 was $13,255,388 and nil for the years ended December 31, 2020 and 2019. Leases The Company determines if an arrangement is a lease at inception. Our lease agreements generally contain lease and non-lease components. Historically, non-lease components such as utilities have been immaterial. Payments under our lease arrangements are primarily fixed. Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is our incremental borrowing rate, because the interest rate implicit in our leases is not readily determinable. Our incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Our lease terms include periods under options to extend or terminate the lease when it is reasonably certain that we will exercise that option. As of December 31, 2021, all of our leases are considered operating leases. Operating lease right-of-use assets and liabilities were included on our Consolidated Balance Sheets beginning January 1, 2019. The Company does not have any finance leases as of December 31, 2021. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses” (Topic 326). ASU 2016-13 provides for a new impairment model which requires measurement and recognition of expected credit losses for most financial assets and certain other instruments, including but not limited to accounts receivable. ASU 2016-13 will become effective for the Company on January 1, 2023 and early adoption is permitted. The Company is currently evaluating the guidance and its impact to the financial statements.

Restatement of Previously Issued 2021 Unaudited Quarterly Financial Statements
Restatement of Previously Issued 2021 Unaudited Quarterly Financial Statements	Note 2 – Restatement of Previously Issued 2021 Unaudited Quarterly Financial Statements During the fourth quarter of 2021 and just before the original 10-K was filed, the Company reviewed its estimate for future expenses related to its Long-Term Incentive Plan for the potential achievement of market capitalization awards, which resulted in increased fair market values on this portion of the new LTIP, first put into place in March 2021. The Company’s Audit Committee concluded, on March 1, 2022, that previously issued unaudited financial statements for all quarterly periods previously filed on Form 10-Q for 2021 should no longer be relied upon. The Audit Committee discussed this matter with the Company’s independent accountant. As a result, the total fair market value under of the market capitalization awards at that time of grant increased to approximately $33.6 million from $12.1 million as of March 31, 2021. This change was a result of management’s determination that the initial fair market value model’s inputs that were utilized were ultimately considered unacceptable according to U.S. GAAP guidance and as a result were revised by management and subsequently updated in its current model for determining the fair market of these market capitalization awards. This error correction was made in the fourth quarter of 2021. The Company’s previously filed unaudited quarterly financial statements for the first three quarters of 2021 filed under Forms 10-Q were affected by the correction of this error. The quarterly periods ending March 31, 2021, June 30, 2021, and September 2021 were restated in the Company’s Annual Form 10-K. Impact of the Restatements The impact of the restatement on the unaudited consolidated balance sheets, statements of changes in stockholders’ equity, statements of operations and statements of cash flows for the 2021 affected quarterly periods is presented below. The change in the amount of stock-based compensation expenses related to the LTIP resulted in the correction of an error in accumulated deficit and additional paid-in capital. The impact of the restatement to the Consolidated Balance Sheets for the three quarters is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 (Unaudited) ​ ​ As Previously ​ ​ ​ ​ ​ ​ Balance Sheet

Revenue Recognition and Contracts with Customers	Note 3 – Revenue Recognition and Contracts with Customers Disaggregated Revenue The Company’s total revenue was comprised of four major product lines: Smart Glasses, OEM Product Sales, Waveguide and Display Engine Sales, and Engineering Services. The following table summarizes the revenue recognized by major product line: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Years Ended December 31, ​ 2021 2020 2019 Revenues ​ ​ ​ Smart Glasses Sales ​ $ 12,784,600 ​ $ 10,081,209 ​ $ 4,893,384 OEM Product Sales ​ — ​ — ​ 951,570 Waveguide and Display Engine Sales ​ — ​ — ​ 152,499 Engineering Services ​ 380,333 ​ 1,500,287 ​ 673,151 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Revenue ​ $ 13,164,933 ​ $ 11,581,496 ​ $ 6,670,604 ​ Significant Judgments Under Topic 606 “Revenue from Contracts with Customers”, we use judgments that could potentially impact both the timing of our satisfaction of performance obligations and our determination of transaction prices used in determining revenue recognized by major product line. Such judgments include considerations in determining our transaction prices and when our performance obligations are satisfied for our standard product sales that include an end-user 30-day right to return if not satisfied with product and general payment terms that are between Net 30 and 60 days. For our Engineering Services, performance obligations are recognized over time using the input method and the estimated costs to complete each project are considered significant judgments. Performance Obligations Revenues from our performance obligations are typically satisfied at a point in time for Smart Glasses, Waveguides and Display Engines, and our OEM Products, which are recognized when the customer obtains control and ownership, which is generally upon shipment. The Company considers shipping and handling activities performed to be fulfillment activities and not a separate performance obligation. The Company also records revenue for performance obligations relating to our Engineering Services over time by using the input method measuring progress toward satisfying the performance obligations. Satisfaction of our performance obligations related to our Engineering Services is measured by the Company’s costs incurred as a percentage of total expected costs to project completion as the inputs of actual costs incurred by the Company are directly correlated with progress toward completing the contract. As such, the Company believes that our methodologies for recognizing revenue over time for our Engineering Services correlate directly with the transfer of control of the underlying assets to our customers. Our standard product sales include a twelve eighteen twelve twelve As of December 31, 2021 and 2020, there was no outstanding performance obligations remaining for extended warranties. The following table presents a summary of the Company’s net sales by revenue recognition method as a percentage of total net sales: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Years Ended December 31, ​ ​ 2021 2020 2019 ​ Point-in-Time 97 % 87 % 90 % Over Time – Input Method 3 % 13 % 10 % ​ ​ ​ ​ ​ ​ ​ ​ Total 100 % 100 % 100 % ​ Remaining Performance Obligations As of December 31, 2021, the Company had no outstanding performance obligations under its engineering services and waveguide development projects, as all projects were completed and delivered in 2021. In addition, the Company had no material outstanding performance obligations related to product sales, other than its standard product warranty.

The federal NOL carryforwards generated in tax years prior to 2018 will began to expire in 2022. The federal NOL carryforwards generated in tax years after 2017 have no expiration. The Company has state NOL carryforwards of approximately $6.8 million available in various jurisdictions in which it files that will begin to expire in 2034. The Company also has approximately $3.9 million of federal and state credit carry-forwards. The federal and state credit carryforwards began to expire in 2022. Utilization of the NOL and credit carryforwards may be subject to an annual limitation in the case of sufficient equity ownership changes under Section 382 of the tax law or the carryforwards may expire unutilized. As the result of the assessment of the FASB ASC 740-10 (Prior Authoritative Literature: FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109), the Company has no unrecognized tax benefits. The Company’s U.S. federal and state tax returns for the years 2018 through 2021 remain subject to examination by the respective tax authorities. FASB ASC 740 (Prior Authoritative Literature: SFAS No. 109, Accounting for Income Taxes), requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on differing treatment of items for financial reporting and income tax reporting purposes. The deferred tax balances are adjusted to reflect tax rates by tax jurisdiction, based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. In light of the historic losses of the Company, a 100% valuation allowance has been recorded to fully offset any benefit associated with the net deferred tax assets, for which realization is not considered more likely than not to occur.

As of December 31, 2021, the authorized shares of common stock under the 2014 Plan, as amended, were 12,734,454. The exercise price per share subject to an option is determined by the administrator, but in the case of an ISO must not be less than the fair market value of a share of our common stock on the date of grant and in the case of a non- statutory stock option must not be less than 100% of the fair market value of a share of our common stock on the date of grant. Under the 2014 Plan, the Company may grant stock options, stock appreciation rights, performance awards of stock and/or cash, and stock awards of restricted stock.

The Black-Scholes-Merton option pricing model was used to estimate the fair value of share-based awards under FASB ASC Topic 718. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and share price volatility. The expected term of options granted was estimated to be the average of the vesting term, historical exercise and forfeiture rates, and the contractual life of the option. The share price volatility at the grant date is estimated using historical stock prices based upon the expected term of the options granted. The risk-free interest rate assumption is determined using the rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. We have never paid cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. Therefore, the assumed expected dividend yield is zero. The following summary table shows the assumptions used to compute the fair value of stock options granted, excluding LTIP, during 2021, 2020 and 2019 and their estimated value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 2020 2019 Assumptions for Black-Scholes: ​ ​ ​ ​ Expected term in years ​ 6.1 to 6.5 ​ 6.2 to 6.6 ​ 6.2 to 6.3 ​ Expected Volatility ​ 82.8% to 86.0 % ​ 73.3% to 76.8 % ​ 79.4% to 89.4 % Risk-free interest rate ​ 0.96% to 1.25 % ​ 0.41% to 0.55 % ​ 1.63% to 1.68 % Expected annual dividends ​ None ​ None ​ None ​ Value of options granted: ​ ​ ​ ​ Number of options granted ​ 1,100,500 ​ 1,481,000 ​ 73,500 ​ Weighted average fair value per share $ 12.40 $ 1.08 $ 1.71 ​ Fair value of options granted $ 13,642,976 $ 1,602,267 $ 125,814 ​ ​ Under FASB ASC Topic 718, “Compensation – Stock Compensation”, the Company has elected to account for forfeitures as they occur. Unrecognized stock-based compensation expense was $9,355,603 as of December 31, 2021, relating to a total of 1,753,995 unvested stock options under the Company’s stock option plans. This stock-based compensation expense is expected to be recognized over a weighted average period of approximately 3.2 years. During the year ended December 31, 2021, the Company issued 68,047 shares of common stock to its independent board members as part of their annual retainer for services covering the period of July 2021 to June 2022 and for the onboarding of the 3 new directors. The fair market value on the date of award of the stock issued was $16.90, resulting in an aggregate fair value of approximately $1,150,000. The unamortized portion is included in Prepaid Expenses and Other Assets on our consolidated balance sheet. The fair market value of these awards is expensed over twelve (12) months for 59,170 shares and twenty-four (24) months for 8,877 shares beginning on July 1, 2021. During the year ended December 31, 2021, the Company awarded 300,000 shares of restricted common stock to the new managing director of its newly established Vuzix Custom Solutions (VCS) business unit, also formerly referred to as Integrated Solutions Business Unit. This equity award was granted pursuant to Nasdaq Listing Rule 5635(c)(4) inducement grant exception as a component of Mr. Spiliotis’s employment compensation and was granted as an inducement material to his acceptance of employment with Vuzix. These restricted shares are subject to vesting, including 50,000 shares that may be earned over 3 years based upon continued employment with the Company, and 250,000 shares that are being held in escrow, and which may be earned upon achievement of revenue and EBITDA operational milestones for VCS within specified periods of time over 5 years. Any such milestone shares will be cancelled if not earned within the appropriate milestone time period. The fair market value on the date of award of the restricted stock issued was $15.58, resulting in an aggregate fair value of approximately $4,674,000, of which, $779,000 has been recorded in short-term and long-term Prepaid Expenses and Other Assets associated with the time vesting option, to be amortized over 36 months beginning October 1, 2021. The balance of shares held in escrow related to the performance-based milestones, representing a fair market value of $3,895,000, is not being amortized until such time as the performance milestones are considered probable to be achieved or have been achieved in accordance with ASC 718. For the years ended December 31, 2021, 2020 and 2019, the Company recorded total stock-based compensation expense, including stock awards but excluding awards under the Company’s LTIP, of $4,047,444, $2,805,842, and $1,498,357, respectively.

Long-term Incentive Plan
Long-term Incentive Plan	Note 15 – Long-term Incentive Plan On March 17, 2021, the Company granted options to purchase a total of 5,784,000 shares of common stock to its officers and certain other members of its management team. The options were granted under the Company’s existing 2014 Incentive Stock Plan. The options have an exercise price of $19.00, with 375,000 options vesting immediately and the remaining portion vesting upon the achievement of certain equity market capitalization milestones, and revenue and EBITDA operational milestones. For the year ended December 31, 2021, the Company recorded non-cash stock-based compensation expense of $13,255,388 for options that vested or are probable to vest. There was no stock-based compensation expense related to the Company’s LTIP in the year ended December 31, 2020 and 2019. The fair value of option grants was calculated using a Monte Carlo simulation on the equity market capitalization tranches and the Black-Scholes-Merton option pricing method on the operational milestone tranches. As of December 31, 2021, we had $28,340,458 of total unrecognized stock-based compensation expense for the portion of options tied to equity market capitalization milestones and the portion of options tied to operational milestones that were considered probable of achievement, all of which will be recognized over a service period of up to 6 years. The probabilities of the milestone achievements are subject to catch-adjustments in each instance where an equity market capitalization milestone is achieved or when an operational milestone becomes probable to be achieved or is achieved. Compensation costs could be reversed in subsequent periods if an awardee leave the Company prior to the expiration of the option life for market capitalization milestone or performance ward vesting of a performance award no longer determined to be probable. If such milestones are achieved earlier in their expected service periods, the remaining unrecognized compensation expense related to that particular milestone would be accelerated and recognized in full during the period where that achievement is affirmed by the Board of Directors. As of December 31, 2021, and going forward, should all of the operational milestones which are currently not yet deemed probable of achievement become probable of achievement or are achieved, then the Company could ultimately recognize up to an additional $34.1 million in non-cash stock-based compensation expense at such time. The following summary table shows the assumptions used to compute the fair value of the equity market capitalization awards and their estimated value: ​ ​ ​ ​ ​ December 31, 2021 ​ Assumptions for Monte Carlo: ​ Expected term in years ​ 1.4 to 5.2 Volatility ​ 70.58 % Risk-free interest rate ​ 0.07 % to 1.28 % Expected annual dividends ​ None Value of options granted: ​ Number of options granted ​ 3,079,500 Weighted average fair value per share $ 10.92 Fair value of options granted $ 33,623,423 ​ The following summary table shows the assumptions used to compute the fair value of the performance-based awards and their estimated value: ​ ​ ​ ​ ​ December 31, 2021 ​ Assumptions for Black-Scholes: ​ Expected term in years ​ 6.0 to 10.0 Expected Volatility ​ 84.67 % to 116.39 % Risk-free interest rate ​ 1.03 % to 1.63 % Expected annual dividends ​ None Value of options granted: ​ Number of options granted ​ 2,704,500 Weighted average fair value per share $ 15.54 Fair value of options granted $ 42,040,151 ​ The unvested remaining equity market and operational milestones under the LTIP with their total related option grants and criteria achievement weightings of the options available for meeting a target are shown in the following table.

Right-of-Use Assets and Liabilities
Right-of-Use Assets and Liabilities	Note 16 — Right-of-Use Assets and Liabilities The Company has signed lease agreements, with the largest being for its office and manufacturing facility in the West Henrietta, New York area under an operating lease that commenced October 3, 2015 and was set to expire on October 3, 2020. This lease has an original five-year term with an option by the Company to renew for two additional three-year terms at pre-agreed to lease rates. On June 25, 2020, the Company exercised the first of two renewal terms, extending our current lease term to January 31, 2024. Operating lease costs under the operating leases totaled $630,085, $559,975 and $572,767 for the years ended December 31, 2021, 2020 and 2019, respectively. Certain leases provide for increases in future minimum annual rental payments as defined in the lease agreements. The leases generally also include real estate taxes and common area maintenance charges in the annual rental payments. Short-term leases are leases having a term of twelve (12) months or less. The Company recognizes short-term leases on an as incurred basis and does not record a related lease asset or liability for such leases. As none of our leases provide an implicit interest rate, we use our incremental borrowing rate to determine our discount rate at lease inception based upon the information available at commencement in determining the present value of lease payments. As of December 31, 2021, the weighted average discount rate was 4.5% and the weighted average remaining lease term was 2.1 years. Future lease payments under operating leases as of December 31, 2021 were as follows: ​ ​ ​ ​ 2022 ​ $ 559,916 2023 ​ 546,916 2024 ​ 45,576 Total Future Lease Payments ​ 1,152,408 Less: Imputed Interest ​ (35,386) Total Lease Liability Balance ​ $ 1,117,022 ​

Summary of Significant Accounting Policies
Operations	Operations Vuzix Corporation (the Company) was formed in 1997 under the laws of the State of Delaware and maintains its corporate offices in West Henrietta, New York (a suburb of Rochester). We are engaged in the design, manufacture, marketing and sale of augmented reality wearable display and computing devices also referred to as head mounted displays (or HMDs, but also known as near-eye displays), in the form of Smart Glasses and Augmented Reality (AR) glasses. Our AR wearable display devices are worn like eyeglasses or attach to a head worn mount. These devices typically include cameras, sensors, and a computer that enable the user to view, record and interact with video and digital content, such as computer data, the Internet, social media or entertainment applications. Our wearable display products integrate micro-display technology with our advanced optics to produce compact high-resolution display engines, less than half an inch diagonally, which when viewed through our smart glasses products create virtual images that appear comparable in size to that of a computer monitor or a large-screen television. The wearable display products we produce can be used for a variety of enterprise, commercial and medical uses and applications, including AR for on-the-go users and as mobile displays and remote service support. Our products are available with varying features and are offered as monocular and binocular display systems.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned UK subsidiary, Vuzix (Europe) Limited. All significant inter-company transactions have been eliminated.
Segment Data, Geographic Information and Significant Customers	Segment Data, Geographic Information and Significant Customers The Company is not organized by market and is managed and operated as one business. A single management team that reports to the chief operating decision maker comprehensively manages the entire business. The Company does not operate any material separate lines of business or separate business entities. Accordingly, the Company does not accumulate discrete information, other than product revenue and material costs, with respect to separate product lines and does not have separately reportable segments as defined by FASB ASC Topic 280, “Disclosures about Segments of an Enterprise and Related Information”. Refer to Note 19 — Geographic and Other Financial Information (Unaudited).
Foreign Currency Transactions	Foreign Currency Transactions The Company considers the US dollar as the functional currency of the Company’s UK Subsidiary. The Company’s UK Subsidiary transacts in Euros and British pounds. All transactions in foreign currencies are recorded in US dollars at the then current exchange rate(s). Upon settlement of the underlying transaction, all amounts are re-measured to US dollars at the current exchange rate on date of settlement. All unsettled foreign currency transactions that remain in accounts receivable and trade account payables are re-measured to US dollars at the period end exchange rates. All re-measurement gains and losses are recorded in the current period net income.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at year-end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Concentration of Credit Risk	Concentration of Credit Risk The Company maintains its cash in bank deposit accounts, which at times may exceed federally insured limits.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents can include highly liquid investments with original maturities of three months or less.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, notes receivable, accounts payable, unearned revenue, accrued expenses, and income taxes payable. As of the consolidated balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented due to the short maturities of these instruments.
Accounts Receivable	Accounts Receivable The Company carries its trade accounts receivable at the invoice amount less an allowance for doubtful accounts. The Company establishes an allowance for uncollectible trade accounts receivable based on the age of outstanding invoices and management’s evaluation of collectability of outstanding balances. These provisions are established when the aging of outstanding amounts exceeds allowable terms and are re-evaluated at each quarter end for adequacy. In determining the adequacy of the provision, the Company considers known uncollectible or at-risk receivables. The allowance for doubtful accounts as of December 31, 2021, 2020 and 2019 was nil. The Company does not accrue interest on any past due accounts receivable unless such receivable goes into collection.
Customer and Supplier Concentrations	Customer and Supplier Concentrations One customer represented 10% of total product revenue and four customers represented 39%, 28%, 16% and 12%, respectively, of our engineering services revenue for the year ended December 31, 2021. No one customer represented more than 10% of total product revenue and two customers represented 48% and 26%, respectively, of our engineering services revenue for the year ended December 31, 2020. One customer represented 16% of total product revenue and one customer represented 100% of engineering services revenue for the year ended December 31, 2019 Three customers represented 27%, 20% and 10%, respectively, of accounts receivable at December 31, 2021. Two customers represented 21% and 14%, respectively, of accounts receivable at December 31, 2020. Three customers represented 32%, 26% and 13%, respectively, of accounts receivable at December 31, 2019. Two third-party vendors represented 38% and 24%, respectively, of material purchases for the year ended December 31, 2021. As of December 31, 2021, the net amount due to these vendors was $504,073.
Accrued Project Revenue	Accrued Project Revenue The Company carries accrued project revenue based on the percentage of completion on the project measured using the input method based upon costs incurred to-date as a percentage of total expected costs to complete the project less amounts invoiced, if any. As of December 31, 2021, 2020 and 2019, we had nil in accrued project revenue.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value using the weighted average first-in, first-out method. The Company includes labor and overhead costs in its inventory valuation costing. The Company records provisions for excess, obsolete or slow-moving inventory based on changes in customer demand, technology developments or other economic factors. The Company’s products have product life cycles that range on average from two to three years currently. At both the product introduction and product discontinuation stage, there is a higher degree of risk of inventory obsolescence. The provision for obsolete and excess inventory is evaluated for adequacy at each quarter end. The estimate of the provision for obsolete and excess inventory is partially based on expected future product sales, which are difficult to forecast for certain products.
Revenue Recognition	Revenue Recognition The Company adopted the new guidance on Revenue from Contracts with Customers under FASB ASC Topic 606, "Revenue from Contracts with Customers", as of January 1, 2018. Product sales represent the majority of the Company’s revenue. The Company recognizes revenue from these product sales as performance obligations are satisfied and transfer of control and ownership to the customer has occurred, typically upon physical shipment. Revenue is recognized in the amount that the Company expects to receive in exchange from the sale of our products. FOB shipping point is our standard shipping term and revenue is recognized as our products ship to customers, as control and ownership are transferred at this point in time. All of our standard product sales include a 30-day money back guarantee and expected returns are estimated at each reporting period date and a portion of revenue is deferred for all estimated returns. As of December 31, 2021 and 2020, deferred revenue associated with our expected returns were immaterial. The Company collects and remits sales taxes in certain jurisdictions and reports revenue net of any associated sales taxes. Revenue from any engineering consulting and other services is recognized at the time the services are rendered. The Company accounts for its longer-term development contracts, which to date have all been firm fixed-priced contracts, on the percentage-of-completion method, whereby income is recognized as work on contracts progresses, but estimated losses on contracts in progress are charged to operations immediately. The percentage-of-completion is determined using the cost-to-cost method. To date, all such contracts have been less than one calendar year in duration.
Unearned Revenue	Unearned Revenue These amounts represent deferred revenue against our expected product sales returns for all December 2021 products sales that are subject to the Company’s 30-day money back guarantee return policy.
Cost of Product Sales	Cost of Product Sales Cost of product sales includes the direct and allocated indirect costs of products sold to customers. Direct costs include labor, materials, reserves for estimated warranty expenses, and other costs incurred directly, or charged to us by our contract manufacturers in the manufacture of these products. Indirect costs include labor, manufacturing overhead, and other costs associated with operating our manufacturing facility and capacity. Manufacturing overhead includes the costs of procuring, inspecting and storing material, facility and other costs, and is allocated to cost of product revenue based on the proportion of indirect labor which supported production activities. Depreciation on manufacturing tools and equipment is included in Operating Expenses in our consolidated statement of operations. The cost of product sales can fluctuate significantly from period to period, depending on the product mix and volume, the level of manufacturing overhead expense and the volume of direct cost of materials.
Cost of Engineering Services Sales	Cost of Engineering Services Sales Cost of engineering services revenues includes both the direct and allocated indirect costs of performing on contracts and producing prototype units. Direct costs include labor, materials and other costs incurred directly in performing under the contract. Direct costs also include labor and other costs associated with operating our research and development department based on the level of effort supporting the development activity. Cost of engineering sales is determined by the level of direct and indirect costs incurred, which can fluctuate substantially from period to period.
Fixed Assets	Fixed Assets Fixed assets are stated at cost. Depreciation of fixed assets is provided for using the straight-line method over the following estimated useful lives: ​ ​ ​ ​ Computers and Purchased Software 3 years Leasehold Improvements Lesser of expected life or lease term Manufacturing Equipment 5 years Tooling 3 years Furniture and Equipment 5 years ​ Repairs and maintenance costs are expensed as incurred. Asset betterments are capitalized and depreciated over their expected useful life.
Patents and Trademarks	Patents and Trademarks The Company capitalizes the costs of obtaining its patents and registration of trademarks. Such costs are accumulated and capitalized during the filing periods, which can take several years to complete. Successful applications that result in the granting of a patent or trademark are then amortized over 15 years on a straight-line basis. Unsuccessful applications are written off and expensed in the fiscal period where the application is abandoned or discontinued. Ongoing maintenance and legal fees for issued patents and trademarks are expensed as incurred.
Software Development Costs	Software Development Costs The Company capitalizes the costs of obtaining or developing its software once technological feasibility has been determined by management or of purchased software solutions when placed into service. Such costs are accumulated and capitalized. Projects can take several years to complete. Unsuccessful or discontinued software projects are written off and expensed in the fiscal period when the software development effort is abandoned or discontinued. Costs incurred internally in researching and developing a computer software product are charged to expense until technological feasibility has been established for the product. Once technological feasibility is established, all software costs are capitalized until the product is available for general release to customers. Judgment is required in determining when technological feasibility of a product is established. Once the product is available for general release, accumulated costs are amortized over the life of the asset. The amortization of these costs is included in cost of product sales over the estimated life of the products, which currently is estimated as three years using a straight-line basis. As of December 31, 2021, 2020 and 2019, we had $541,666, $458,333 and $100,000, respectively, of net software development costs included in Other Assets. For the years ended December 31, 2021, 2020 and 2019, there was nil in impairment of software development costs.
Licenses	Licenses The Company capitalizes the costs of acquiring licenses and prepaid royalties. They are amortized on either a per unit basis or straight line over the life of the license. In some cases, future royalties are subject to annual limits.
Long-Lived Assets	Long-Lived Assets The Company at least annually assesses all of its long-lived assets for impairment and when events or circumstances indicate their carrying amounts may not be recoverable, in accordance with FASB ASC Topic 360-10, “Accounting for the Impairment or Disposal of Long-Lived Assets.” For the years ended December 31, 2021 and 2020, there was an impairment charge of $80,163 and $73,532, respectively, to Patents and Trademarks and nil in 2019. For the year ended December 31, 2021, we recorded a loss on fixed asset disposal of $183,614 upon the retirement of certain tooling and manufacturing equipment assets no longer in use. No loss on fixed asset disposal charges on tooling and equipment were recorded in 2020 or 2019.
Research and Development	Research and Development Research and development costs are expensed as incurred consistent with the guidance of FASB ASC Topic 730, “Research and Development,” and include employee related costs, office expenses, third-party design and engineering services, and new product prototyping costs. Costs incurred internally in researching and developing a computer software product are charged to expense until technological feasibility has been established for the product.
Shipping and Handling Costs	Shipping and Handling Costs Amounts charged to customers and costs incurred by the Company related to shipping and handling are included in net sales and cost of sales, respectively.
Provision for Future Warranty Costs	Provision for Future Warranty Costs The Company provides for the estimated returns under warranty and the costs of fulfilling our obligations under product warranties at the time the related revenue is recognized. The Company estimates the costs based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific warranty terms and conditions vary depending upon the country in which we do business, but generally include parts and labor over a period generally ranging from one to two years from the date of product shipment. The Company provides a reserve for expected future warranty returns at the time of product shipment or produces over-builds to cover replacements. We regularly reevaluate our estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary each quarter end, based upon historical experience of warranty claims and costs.
Advertising	Advertising Advertising costs are expensed as incurred and recorded in “Selling and Marketing” in the Consolidated Statements of Operations. Advertising expense for the years ended December 31, 2021, 2020 and 2019 was $1,263,897, $974,461 and $1,302,120, respectively.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740-10, “Income Taxes.” Accordingly, the Company provides deferred income tax assets and liabilities based on the estimated future tax effects of differences between the financial and tax bases of assets and liabilities based on currently enacted tax laws. A valuation allowance is established for deferred tax assets in amounts for which realization is not considered more likely than not to occur. The Company reports any interest and penalties accrued relating to uncertain income tax positions as a component of the income tax provision.
Net Loss Per Share	Net Loss Per Share Basic earnings per share is computed by dividing the net income (loss) less accrued dividends on any outstanding preferred stock by the weighted average number of common shares outstanding for the period. Diluted earnings per share calculations reflect the assumed exercise of all dilutive employee stock options and warrants applying the treasury stock method promulgated by FASB ASC Topic 260, “Earnings Per Share” and the conversion of any outstanding convertible preferred shares or notes payable that are-in-the-money, applying the as-if-converted method. However, if the assumed exercise of stock options and warrants and the conversion of any preferred shares or convertible notes payable are anti-dilutive, basic and diluted earnings per share are the same for all periods. As a result of the net losses generated in 2021, 2020 and 2019, all outstanding instruments would be antidilutive. As of December 31, 2021, 2020 and 2019, there were 8,606,062, 14,872,703 and 12,858,707 common stock share equivalents, respectively, that were potentially issuable under stock options, conversion of preferred shares (excluding accrued dividends), and stock warrants that could potentially dilute basic earnings per share in the future.
Stock-Based Compensation Expense	Stock-Based Compensation Expense The Company accounts for stock-based compensation to employees and directors in accordance with FASB ASC Topic 718 “Compensation - Stock Compensation,” which requires that compensation expense be recognized in the consolidated financial statements for stock-based awards based on the grant date fair value. For stock option awards, the Black-Scholes-Merton option pricing model was used to estimate the fair value of share-based awards under FASB ASC Topic 718. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and share price volatility. The expected term of options granted was estimated to be the average of the vesting term, historical exercise and forfeiture rates, and the contractual life of the option. The share price volatility at the grant date is estimated using historical stock prices based upon the expected term of the options granted. The risk-free interest rate assumption is determined using the rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. For common stock awards, the Company uses the fair market value of our common stock on the date of each stock-based award based on the market price of the Company’s common shares and the expense related to these awards is recognized over the requisite service period of the awards on a straight-line or graded vesting basis, which is generally commensurate with the vesting term. Stock-based compensation expense associated with stock awards and stock option grants for the years ended December 31, 2021, 2020 and 2019 was $4,047,444, $2,805,842 and $1,498,357, respectively, excluding awards under the Company’s Long-term Incentive Plan (LTIP). The Company issues new shares upon stock option exercises. For stock options awarded under the Company's LTIP, options vest only upon the achievement of certain equity market conditions or performance-based milestones. The fair value of options granted under this program were calculated by using a Monte Carlo simulation for the equity market condition tranches and the Black-Scholes-Merton option pricing method on the performance-based tranches. Stock-based compensation expense associated with the Company's LTIP for the year ended December 31, 2021 was $13,255,388 and nil for the years ended December 31, 2020 and 2019.
Leases	Leases The Company determines if an arrangement is a lease at inception. Our lease agreements generally contain lease and non-lease components. Historically, non-lease components such as utilities have been immaterial. Payments under our lease arrangements are primarily fixed. Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is our incremental borrowing rate, because the interest rate implicit in our leases is not readily determinable. Our incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Our lease terms include periods under options to extend or terminate the lease when it is reasonably certain that we will exercise that option. As of December 31, 2021, all of our leases are considered operating leases. Operating lease right-of-use assets and liabilities were included on our Consolidated Balance Sheets beginning January 1, 2019. The Company does not have any finance leases as of December 31, 2021.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses” (Topic 326). ASU 2016-13 provides for a new impairment model which requires measurement and recognition of expected credit losses for most financial assets and certain other instruments, including but not limited to accounts receivable. ASU 2016-13 will become effective for the Company on January 1, 2023 and early adoption is permitted. The Company is currently evaluating the guidance and its impact to the financial statements.
