Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Financial Statement Presentation The consolidated financial statements include the accounts of Iridex and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Our fiscal year ends on the Saturday closest to December 31. Fiscal 2022 ended on December 31, 2022 (“FY 2022”) and Fiscal 2021 ended on January 1, 2022 (“FY 2021”). Fiscal years 2022 and 2021 each included 52 weeks of operations. Use of Estimates. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. In addition, any change in these estimates or their related assumptions could have an adverse effect on our operating results. Cash and Cash Equivalents We consider all highly liquid debt instruments with insignificant interest rate risk and an original maturity of three months or less when purchased to be cash equivalents. Our cash equivalents consist primarily of cash deposits in money market funds that are available for withdrawal without restriction. Sales Returns Allowance and Allowance for Doubtful Accounts When determining the transaction price, we estimate the variable consideration as the most likely amount to which we expect to be entitled, and we include the estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue will not occur when the uncertainty associated with the variable consideration is resolved. Material differences may result in the amount and timing of our revenue for any period if management made different judgments or utilized different estimates. Our provision for sales returns is recorded net of the associated costs. There was no provision for sales returns as of December 31, 2022 and January 1, 2022. Similarly management must make estimates regarding the uncollectibility of accounts receivable. We are exposed to credit risk in the event of non-payment by customers to the extent of amounts recorded on the consolidated balance sheets. As sales levels change, the level of accounts receivable would likely also change. In addition, in the event that customers were to delay their payments to us, the levels of accounts receivable would likely increase. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The allowance for doubtful accounts is based on past payment history with the customer, analysis of the customer’s current financial condition, the aging of the accounts receivable balance, customer concentration and other known factors. A reconciliation of the changes in our allowance for doubtful accounts balances for the years ended December 31, 2022 and January 1, 2022 are as follows (in thousands):

Inventories Inventories are stated at the lower of cost or net realizable value and include on-hand inventory physically held at our facility, sales demo inventory and service loaner inventory. Cost is determined on a standard cost basis which approximates actual cost on a first-in, first-out (“FIFO”) method. Lower of cost or net realizable value is evaluated by considering obsolescence, excessive levels of inventory, deterioration and other factors. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess, obsolescence or impaired inventory and are charged to cost of revenues. Once the cost of the inventory is reduced, a new lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Factors influencing these adjustments include changes in demand, product life cycle and development plans, component cost trends, product pricing, physical deterioration and quality issues. Revisions to these adjustments would be required if these factors differ from our estimates. As part of our normal business, we generally utilize various finished goods inventory as either sales demos to facilitate the sale of our products to prospective customers, or as loaners that we allow our existing customers to use while we repair their products. We are amortizing these demos and loaners over an estimated useful life of four years. The amortization of the demos is charged to sales and marketing expense while the amortization on the loaners is charged to cost of revenues. The gross value of demos and loaners was $1.9 million and $2.0 million and the accumulated amortization was $1.7 million and $1.7 million as of December 31, 2022 and January 1, 2022, respectively. The net book value of demos and loaners is charged to cost of revenues if and when such demos or loaners are sold. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated on a straight–line basis over the estimated useful lives of the assets, which is generally three year. Leasehold improvements are amortized over the lesser of their estimated useful lives or the lease term. Repairs and maintenance costs are expensed as incurred. Leases We determine if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use (“ROU”) assets, net and Operating lease liabilities in our consolidated balance sheets. As of December 31, 2022, the Company was not a party to finance lease arrangements. Operating lease ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Under the available practical expedient, we account for the lease and non-lease components as a single lease component. Valuation of Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company reviews goodwill for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company performs an annual impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. As the Company uses the market approach to assess impairment, its common stock price is an important component of the fair value calculation. If the Company’s stock price continues to experience significant price and volume fluctuations, this will impact the fair value of the reporting unit and can lead to potential impairment in future periods. The Company performed its annual impairment test during the second quarter of fiscal 2022 and determined that its goodwill was not impaired. As of December 31, 2022, we had not identified any factors that indicated there was an impairment of our goodwill and determined that no additional impairment analysis was then required. Intangible assets with definite lives are amortized over the useful life of the asset. We review our amortizing intangible assets for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable. An asset is considered impaired if its carrying amount exceeds the future non-discounted net cash flow the asset is expected to generate. If an asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. In such circumstances, we conduct an impairment analysis in accordance with Accounting Standards Codification (“ASC”) 350, “Intangibles – Goodwill and Other” (“ASC 350”). Revenue Recognition Our revenues arise from the sale of laser consoles, delivery devices, consumables, service, and support activities. We also derive revenue from royalties from third parties which are typically based on licensees’ net sales of products that utilize our technology. Our revenue is recognized in accordance with ASC 606, “Revenue from Contracts with Customers.” The Company recognizes revenue using the five-step model: (1) identifying the contract with the customer, (2) identifying the performance obligations in the contract, (3) determining expected transaction price, (4) allocating the transaction price to the distinct performance obligations in the contract, and (5) recognizing revenue when (or as) the performance obligations are satisfied. The Company has the following revenue transaction types: (1) Product Sale Only, (2) Service Contracts, (3) System Repairs (outside of warranty), (4) Royalty Revenue and (5) Exclusive Distribution Rights. (1) Product Sale Only: The Company’s products consist of laser consoles, delivery devices and consumable instrumentation, including laser probes. The Company’s products are currently sold for use by ophthalmologists specializing in the treatment of glaucoma and retinal diseases. Inside the United States and Germany the products are sold directly to the end users. In other countries outside of the United States and Germany, the Company utilizes independent, third-party distributors to market and sell the Company’s products. There is no continuing obligation after shipment is made to these distributors. The Company recognizes revenue from product sale at a point in time subject to the allocation of transaction price to additional performance obligations, if any. (2) Service Contracts: The Company offers a standard two-year warranty on all system sales. The Company also offers a service contract which is sold to customers in incremental, one-year periods which begin subsequent to the expiration of the standard two-year warranty. The customer can opt to purchase the service contract at the time of the system sale or after the initial system sale. The Company recognizes revenue from service contracts ratably over the service period. Revenue recognition for the sale of a service contract is largely dependent on the timing of the sale as follows: a. Service Contract Sale in Conjunction with System Sale: If the customer opts to purchase a service contract at the time of the system sale, the Company allocates the transaction price of the distinct performance obligations in the contract by determining stand-alone selling price using historical pricing net of any variable consideration or discounts to specifically allocate to a particular performance obligation. b. Service Contract Sale Subsequent to System Sale: If the customer opts to purchase a service contract after the initial system sale, the Company determines the amount of time that has elapsed since the initial system sale. If the service contract is purchased within 60 days of the initial sale, the Company considers this sale to be an additional element of the original sale and allocates the transaction price of the distinct performance obligations in the contract by determining stand-alone selling price using historical pricing net of any variable consideration or discounts to specifically allocate to a particular performance obligation. If the service contract is purchased subsequent to 60 days after the initial sale, the sale of the service contract is deemed a separate contract and is deferred at the selling price and recognized ratably over the extended warranty period as the performance obligation is satisfied. (3) System Repairs (outside of warranty): Customers will occasionally request repairs from the Company subsequent to the expiration of the standard warranty and outside of a service contract. The Company recognizes revenue from system repairs (outside of warranty) at a point in time. When the customer requests repairs from the Company subsequent to the expiration of the standard warranty and outside of a service contract, these repair contracts are considered separate from the initial sale, and as such, revenue is recognized as the repair services are rendered and the performance obligation satisfied. (4) Royalty Revenue: The Company has royalty agreements with four customers related to sale of the Company’s intellectual property. Under the terms of these agreements, three customers are to remit a percentage of sales to the Company as the sales occur and one customer made an upfront prepayment for royalties. The arrangements with three customers are for sales-based licenses of intellectual property, for which the guidance in paragraph ASC 606-10-55-65 applies. Therefore, the Company recognizes revenue at a point in time, only as the subsequent sale occurs. However, the Company notes that such sales being reported by the licensee with a quarter in arrear, such revenue is recognized at the time it is reported and paid by the licensee given that any estimated variable consideration would have to be fully constrained due to the unpredictability of such estimate and the unavoidable risk that it may lead to significant revenue reversals. For the arrangement with one customer, the Company had concluded that there is one combined performance obligation to be satisfied. Therefore, the Company recognizes revenue related to this arrangement over time. (5) Exclusive Distribution Rights: In March 2021, the Company entered into a distribution agreement with Topcon, pursuant to which the Company granted Topcon the exclusive right to distribute the Company’s retina and glaucoma products in certain geographies outside the United States. The exclusivity arrangement with Topcon obligates the Company to provide training, customer support, and exclusive territorial rights to Topcon for certain international regions, for a period of 10 years, commencing upon regulatory approval to transfer existing (non-exclusive) distribution rights from the current distributors in those regions to Topcon. The Company has the right to terminate the exclusive distribution rights granted to Topcon for any of the regions at any point in time during the 10-year exclusivity term for a termination fee that is based on a multiple of 1.2 times the revenue generated by the Company in 2019 for the respective region. Management has determined that the exclusivity rights, training, and customer support represents a single combined performance obligation for each region, to be recognized as exclusivity fee revenue on a straight-line basis over the 10-year period for each region, commencing on the date that regulatory approval is obtained for each region, based on the SSP for such combined performance obligation for each region. The estimated fair value of the exclusive distribution rights for all regions combined totaled approximately $14.8 million. Of this amount, management has fully-constrained and returned to Topcon the arrangement fee allocated to Belarus (approximately $0.2 million) because obtaining the necessary regulatory approvals and termination of existing distributor relationship was not feasible. During fiscal years ended 2022 and 2021, $1.3 million and $0.6 million in revenue related to the exclusive distribution rights was recorded, respectively. Costs of Obtaining Revenue Contracts The Company recognized assets from certain costs incurred to obtain revenue contracts. These costs relate to sales commissions arising from the sale of our products. The costs are considered incremental and recoverable of obtaining revenue contracts with customers. These deferred costs are amortized on a straight-line basis over the estimated period of benefit, which typically ranges from 2 to 3 years. As of December 31, 2022 and January 1, 2022, we recognized deferred costs incurred to obtain revenue contracts with customers, net of accumulated amortization, of $0.2 million and $0, respectively, and included these amounts in Prepaid expenses and other current assets and Other long-term assets in the Company’s consolidated balance sheets. Amortization expense was $36 thousand and $0, respectively, for the fiscal years ended December 31, 2022 and January 1, 2022. There were no impairment expenses for both the fiscal years ended December 31, 2022 and January 1, 2022, respectively. Sales commissions that do not represent incremental and recoverable costs of obtaining a contract are expensed as incurred. As a practical expedient, the Company will not recognize such sales commission as a contract asset but rather recognize as expense when incurred if the amortization period of the asset that the Company would have otherwise recognized is one year or less. Contract Fulfillment Costs The Company recognized an asset from the costs incurred to fulfill a contract. These costs relate directly and must be incurred to satisfy performance obligations on certain specific contract with a customer. These costs are expected to be recovered over time and are amortized on a systematic basis that is consistent with the recognition of revenue to which it relates. As of December 31, 2022 and January 1, 2022, we recognized deferred costs incurred to fulfill a contract with a customer, net of accumulated amortization, of $0.8 million and $0.3 million, respectively, and included these amounts in Prepaid expenses and other current assets and Other long-term assets in the Company’s consolidated balance sheets. Amortization expense was $62 thousand and $0, respectively, for the fiscal years ended December 31, 2022 and January 1, 2022. There were no impairment expenses for both the fiscal years ended December 31, 2022 and January 1, 2022, respectively. Taxes Collected from Customers and Remitted to Governmental Authorities Taxes collected from customers and remitted to governmental authorities are recognized on a net basis in the accompanying consolidated statements of operations as well as accrued expenses to the degree which is appropriate. Deferred Revenue Deferred revenue represents contract liabilities. Revenue related to extended service contracts is deferred and recognized on a straight-line basis over the period of the applicable service period. Costs associated with these service arrangements are recognized as incurred. A reconciliation of the changes in our deferred revenue balances for the years ended December 31, 2022 and January 1, 2022 are as follows (in thousands):
FY 2020: Balance as of January 2, 2021 |  | $ | 1,227 |
Additions to deferral |  |  | 14,503 |
Revenue recognized |  |  | (2,445 | )
FY 2021: Balance as of January 1, 2022 |  |  | 13,285 |
Additions to deferral |  |  | 4,051 |
Revenue recognized |  |  | (3,183 | )
FY 2022: Balance as of December 31, 2022 |  | $ | 14,153 |
During each of the twelve months ended December 31, 2022 and January 1, 2022, approximately $2.3 million and $0.9 million were recognized pertaining to amounts deferred as of January 1, 2022 and January 2, 2021, respectively. Warranty We provide reserves for the estimated cost of product warranties at the time revenue is recognized based on historical experience of known product failure rates and expected material and labor costs to provide warranty services. We generally provide a two-year warranty on our products. The Company’s warranty policy is applicable to products which are considered defective in their performance or fail to meet the product specifications. Additionally, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. If estimates are determined to be greater than the actual amounts necessary, we may reverse a portion of such provisions in future periods. Warranty costs are reflected in the consolidated statements of operations as costs of revenues. A reconciliation of the changes in our warranty liability for the years ended December 31, 2022 and January 1, 2022 are as follows (in thousands):
FY 2020: Balance as of January 2, 2021 |  | $ | 247 |
Accruals for product warranties |  |  | 105 |
Cost of warranty claims |  |  | (158 | )
Adjustment to pre-existing warranties |  |  | (36 | )
FY 2021: Balance as of January 1, 2022 |  |  | 158 |
Accruals for product warranties |  |  | 132 |
Cost of warranty claims |  |  | (232 | )
Adjustment to pre-existing warranties |  |  | 216 |
FY 2022: Balance as of December 31, 2022 |  | $ | 274 |
Shipping and Handling Costs Our shipping and handling costs billed to customers are included in revenues and the associated expense is recorded in cost of revenues for all periods presented. Shipping and handling costs billed to customers amounted to $0.3 million and $0.3 million during fiscal years 2022 and 2021, respectively. Research and Development Research and development expenditures are charged to operations as incurred. Advertising Advertising and promotion costs are expensed as they are incurred; such costs were approximately $0.4 million in 2022 and $0.2 million in 2021 and are included in sales and marketing expenses in the accompanying consolidated statements of operations. Income Taxes We account for income taxes in accordance with ASC 740, “Income Taxes” (“ASC 740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. Under ASC 740, the liability method is used in accounting for income taxes. Deferred tax assets and liabilities are determined based on the differences between financial reporting and the tax basis of assets and liabilities, and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. ASC 740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. We annually evaluate the realizability of our deferred tax assets by assessing our valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization include our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets. As of December 31, 2022, based on the Company's recent history of losses and its forecasted losses, management believes on the more likely than not basis that a full valuation allowance is required. Accordingly, as of December 31, 2022, the Company provided a full valuation allowance on its federal and states deferred tax assets. Accounting for Uncertainty in Income Taxes We account for uncertain tax positions in accordance with ASC 740. ASC 740 seeks to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax provision that an entity takes or expects to take in a tax return. Additionally, ASC 740 provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosures, and transition. Under ASC 740, an entity may only recognize or continue to recognize tax positions that meet a "more-likely-than-not" threshold. In accordance with our accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. There were no accrued interest and penalties during the years ended December 31, 2022 and January 1, 2022. Accounting for Stock-Based Compensation We account for stock-based compensation granted to employees and directors, including employees stock option awards and restricted stock units in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”). Accordingly, stock-based compensation cost is measured at grant date, based on the fair value of the award. Stock-based compensation is recognized as expense on a ratable basis over the requisite service period of the award. We value options using the Black-Scholes option pricing model. Time-based restricted stock units are valued at the grant date fair value of the underlying common shares. Performance-based restricted stock units without market conditions are valued at grant date fair value of the underlying common shares. Performance-based RSUs granted with market conditions and performance-based stock options with market conditions are valued using the Monte Carlo simulation model. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions which determine the fair value of stock-based awards, including the option’s expected term and the price volatility of the underlying stock. The Monte Carlo simulation model incorporates assumptions for the holding period, risk-free interest rate, stock price volatility and dividend yield. Concentration of Credit Risk and Other Risks and Uncertainties Our cash and cash equivalents are deposited in demand and money market accounts. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and therefore, bear minimal risk. We market our products to distributors and end-users throughout the world. Sales to international distributors are generally made on open credit terms and letters of credit. Management performs ongoing credit evaluations of our customers and maintains an allowance for potential credit losses. Historically, we have not experienced any significant losses related to individual customers or a group of customers in any particular geographic area. For the year ended December 31, 2022, one customer, Topcon, accounted for greater than 10% of total revenues, representing 28%. For the year ended January 1, 2022, one customer, Topcon, accounted for greater than 10% of total revenues, representing 21%. For the year ended December 31, 2022, one customer, Topcon, accounted for over 10% of our accounts receivable, representing 37%. As of January 1, 2022, two customers, including Topcon, accounted for over 10% of our accounts receivable, representing 31% and 11%, respectively. Our products require approvals from the Food and Drug Administration and international regulatory agencies prior to commercialized sales. Our future products may not receive required approvals. If we were denied such approvals, or if such approvals were delayed, it would have a material adverse impact on our business, results of operations and financial condition. Reliance on Certain Suppliers Certain components and services used to manufacture and develop our products are presently available from only one or a limited number of suppliers or vendors. The loss of any of these suppliers or vendors would potentially require a significant level of hardware and/or software development efforts to incorporate the products or services into our products. Net Income (Loss) per Share Basic net income (loss) per share is based upon the weighted average number of common shares outstanding during the period. Diluted net income per share is based upon the weighted average number of common shares outstanding and dilutive common stock equivalents outstanding during the period. Common stock equivalents consist of incremental common shares issuable upon the exercise of stock options and release (vesting) of restricted stock units and awards and are calculated under the treasury stock method. Common stock equivalent shares from unexercised stock options and unvested restricted stock units are excluded from the computation for periods in which we incur a net loss or if the exercise price of such options is greater than the average market price of our common stock for the period as their effect would be anti-dilutive. See Note 18 - Computation of Basic and Diluted Net Loss Per Common Share. Reclassifications Certain reclassifications have been made to the prior year consolidated financial statements included in these consolidated financial statements to conform to the current year presentation. The reclassifications had no impact on previously reported net loss, accumulated deficit, total assets, or total liabilities. Foreign Currency Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using rates that approximate those in effect during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive income (loss). Implementation Costs Incurred in a Cloud Computing Service Arrangement The Company is currently implementing a new enterprise resource planning (“ERP”) system. The new ERP system operates in a cloud-based environment. The Company concluded that this cloud computing arrangement does not include a license, and therefore, will account for this arrangement as one that is a service contract. As of December 31, 2022, the Company capitalized $0.7 million in implementation costs, included in Prepaid expenses and other current assets and Other long-term assets in the Company’s condensed consolidated balance sheets. The Company will amortize the capitalized implementation costs over 5 years on a straight-line basis once the ERP system is ready for use. There were no amortization expenses for the fiscal year ended December 31, 2022. Recently Adopted Accounting Standards In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” as part of its initiative to reduce complexity in the accounting standards. The standard eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The standard also clarifies and simplifies other aspects of the accounting for income taxes. The Company adopted ASU 2019-12 in fiscal year 2021 and the standard did not have a material impact on its consolidated financial statements.
