In July 2017,During the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-11,"Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815)." The amendments in Part Inine months ended September 30, 2023, the Company recognized $19.3 million of this ASU change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity classified financial instruments, the amendments require entitiesrevenue that present earnings per share (EPS) in accordance with Topic 260 to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features are now subject to the specialized guidance for contingent beneficial

conversion features (in Subtopic 470-20, Debt-Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). The amendments in Part II of this ASU recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending contentwas included in the FASB codification, to a scope exception. Those amendments do not have an accounting effect. This ASU is effective for interim and annual reporting periods beginning aftercontract balances as of December 15, 2018. Early adoption is permitted, including adoption in an interim period. The31, 2022. During the nine months ended September 30, 2022, the Company is currently evaluating the impactrecognized $21.7 million of revenue that this guidance will have on its consolidated financial statements.
In May 2017, the FASB issued ASU No. 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting," which amends the scope of modification accounting for share-based payment arrangements. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. This ASU is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.
In March 2017, the FASB issued ASU No. 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Topic 310): Premium Amortization on Purchased Callable Debt Securities," which amends the amortization period for certain purchased callable debt securities held at a premium. This ASU will shorten the amortization period for the premium to be amortized to the earliest call date. This ASU does not apply to securities held at a discount, which will continue to be amortized to maturity. This ASU is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This ASU is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." The amendment seeks to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. This ASU is effective for interim and annual reporting periods beginning after December 15, 2017, including interim periods within those periods. The amendments should be applied prospectively on or after the effective dates. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.
In August 2016, the FASB issued ASU No. 2016-15 which amends the guidance on the classification of certain cash receipts and paymentswas included in the statement of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and is applied retrospectively. Early adoption is permitted including adoption in an interim period. The Company is currently evaluating the impact that this guidance will have on its financial condition and results of operations.
In June 2016, the FASB issued ASU No. 2016-13. The purpose of this ASU is to require a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. This ASU is effective for interim and annual reporting periods beginning after December 15, 2019. The Company is currently evaluating the impact that this guidance will have on its financial condition and results of operations.
In March 2016, the FASB issued ASU No. 2016-09, "Improvements to Employee Share-Based Payment Accounting." This ASU simplifies the accounting for share-based payment transactions including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification in the statement of cash flows. The updated standard no longer requires cash flows related to excess tax benefits to be presented as a financing activity separate from other income tax cash flows. The update also allows entities to repurchase more of an employee's shares for tax withholding purposes without triggering liability accounting, clarifies that all cash payments to taxing authorities made on an employee's behalf for withheld shares should be presented as a financing activity on the statement of cash flows, and provides for an accounting policy election to account for forfeitures as they occur. The Company adopted this ASU on January 1, 2017. The impact of the adoption is as follows:
This ASU requires excess tax benefits to be recognized regardless of whether the benefit reduces taxes payable. The adoption of this guidance on a modified retrospective basis resulted in the recognition of a cumulative-effect adjustment of $38.2 million that reduced the Company's accumulated deficit and increased its deferred tax assetscontract balances as of January 1, 2017. The previously unrecognized California excess tax effects were recorded as a deferred tax asset net of a valuation allowance.December 31, 2021.

Remaining Performance Obligations
The Company has electedRevenue allocated to continueremaining performance obligations represents the transaction price allocated to estimate forfeitures expected to occur to determine the amount of stock-based compensation cost to be recognized in each period. As such, the guidance relating to forfeitures did not have an impact on its accumulated deficit as of January 1, 2017.
Additionally, the Company anticipates the potential for increased periodic volatility in future effective tax rates as a result of the continued application of ASU No. 2016-09.
In February 2016, the FASB issued ASU No. 2016-02, "Leases." This ASU requires lessees to recognize right-of-use assets and liabilities for operating leases, initially measured at the present value of the lease payments, on the balance sheet. In addition, it requires lessees to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. This ASU will become effective for the Company in the first quarter of fiscal year 2019, and requires adoption using a modified retrospective approach. The Company is evaluating the impact of adopting this new accounting standard update on its consolidated financial statements and related disclosures and anticipates this new guidance will materially impact the Company’s financial statements given the Company has a significant number of operating leases.
In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory (Topic 330)," which applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventory that is measured using last-in, last-out (“LIFO”). This ASU is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. The Company adopted this ASU on January 1, 2017. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers(Topic 606) (“Standard”). The core principle of the Standard is for a company to recognize revenue for goods or services transferred to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. To do so, a company will be required to exercise more judgment and make more estimates than under current guidance, including in identifying the performance obligations included in the arrangement, estimating and revising the variable consideration, if any, to be included in the transaction price and allocating the transaction price to distinct performance obligations. The FASB further clarified the Standard by issuing ASU No. 2016-10 (Identifying Performance Obligations and Licensing); ASU No. 2016-12 (Narrow-Scope Improvements and Practical Expedients); and ASU No. 2016-20 (Technical Corrections and Improvements).
The Standard may be applied retrospectively to each prior period presented (full retrospective method) or retrospectively with the cumulative effect recognized as of the date of initial application (modified retrospective method). The Standard, as amended, is effective for the Company on January 1, 2018. The Company has yet to make a final decision regarding the adoption method it will use but believes it will adopt the Standard on a full retrospective basis, with a cumulative-effect adjustment to the opening balance of retained earnings on January 1, 2016 determined on the basis of the impact of the Standard on the accounting for contracts that are not completed as ofunsatisfied, or partially unsatisfied, which includes unearned revenue and amounts that date.
Although the Company has yet to finalize its evaluation and quantification of the effects that the Standard will have on its consolidated financial statements, and to finalize the design and implementation of related changes to its policies, procedures and controls, the Company expects the Standard to materially impact the timing of revenue recognition for its fixed-fee intellectual property (IP) licensing arrangements (including certain fixed-fee agreements that license the Company's existing IP portfolio as well as IP added to this portfolio during the license term) as a majority of such revenue would be recognized at inception of the license term, as opposed to over time as is the case under current U.S. GAAP, and the Company will be required to computeinvoiced and recognize interest income over time as control over the IP generally transfers significantly in advance of cash being received from customers. In addition, the Company is currently assessing its minimum guarantee contracts to determine whether, under the Standard, revenue should be recognized at contract inception or over the contract term. The Company expects that any change to current revenue recognition practices may significantly increase volatility in its quarterly revenue trends.
In accordance with existing U.S. GAAP, the Company currently recognizes revenue from per-unit royalty-based IP licenses in the period the licensee reports its sales, generally in the quarter after the underlying sales by the licensee occurred. On adoption of the Standard, such royalties will be recognized as revenue during the period in future periods. Contracted but unsatisfied performance obligations were approximately $20.0 million as of September 30, 2023, which the licensee's sales are estimatedCompany primarily expects to have occurred, which will result in an adjustment to revenue when actual amounts are subsequently reported byrecognize over the Company's licensees.next 2 years.
Aspart of the Company’s assessment and implementation plan, the Company is evaluating and implementing changes to its policies, procedures and controls.


3. Earnings (Loss) Per Share
Basic earnings (loss) per share is calculated by dividing the net income (loss) by the weighted averageweighted-average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing the earnings by the weighted averageweighted-average number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist of incremental common shares issuable upon exercise of stock options, employee stock purchases, restricted stock and restricted stock units and shares issuable upon the conversion of convertible notes. The dilutive effect of outstanding shares is reflected in diluted earnings per share by application of the treasury stock method.method, or the if-converted method for the in-the-money conversion feature of the 2023 Notes. This method includes consideration of the amounts to be paid by the employees,

the amount of excess tax benefits that would be recognized in the equity if the instrument was exercised and the amount of unrecognized stock-based compensation related to future services. No potential dilutive common shares are included in the computation of any diluted per share amount when a net loss is reported.

It is reasonably possible that the businesses could perform significantly below the Company's expectations or a deterioration of market and economic conditions could occur. This would adversely impact the Company's ability to meet its projected results, which could cause the goodwill in any of its reporting units or long-lived assets in any of its asset groups to become impaired.

As of September 30, 2017,2023, there was $0.1$0.2 million of total unrecognized compensation cost related to stock-based compensation arrangements granted under the 2015 ESPP. That cost is expected to be recognized over one month.
Tax benefits realized as a result of employee stock option exercises, stock purchase plan purchases, and vesting of equity stock and stock units for the three and nine months ended September 30, 2017 calculated in accordance with accounting for share-based payments were $0.2 million and $0.8 million, respectively. There were no tax benefits realized as a result of employee stock option exercises, stock purchase plan purchases, and vesting of equity stock and stock units for the three and nine months ended September 30, 2016 calculated in accordance with accounting for share-based payments.
Valuation Assumptions
The fair value of stock awards is estimated as of the grant date using the Black-Scholes-Merton (“BSM”) option-pricing model assuming a dividend yield of 0% and the additional weighted-average assumptions as listed in the table below.

The following table presents the weighted-average assumptions used to estimate the fair value of stock options granted that contain only service conditions in the periods presented.

Nonvested Equity Stock and Stock Units
The Company grants nonvested equity stock units to officers, employees and directors. During the three andmonths ended September 30, 2023, the Company granted an immaterial amount of nonvested equity stock units. During the nine months ended September 30, 2017,2023, the Company granted nonvested equity stock units totaling 463,346 and 2,654,508 shares under the 2015 Plan.approximately 1.2 million shares. During the three and nine months ended September 30, 2016,2022, the Company granted nonvested equity stock units totaling 884,724approximately 0.5 million and 2,909,3642.2 million shares, under the 2015 Plan.respectively. These awards have a service condition, generally a service period of four years, except in the case of grants to directors, for which the service period is 1one year. For the three and nine months ended September 30, 2017,2023, the nonvested equity stock units were valued at the date of grant giving them a fair value of approximately $6.0$2.1 million and $34.1 million.$57.3 million, respectively. For the three and nine months ended September 30, 2016,2022, the nonvested equity stock units were valued at the date of grant giving them a fair value of approximately $12.6$12.8 million and $37.6 million.$61.8 million, respectively. During the first quartersquarter of 20172023 and 2016,2022, the Company granted performance unit awards to certain Companycompany executive officers with vesting subject to the achievement of certain performance and/or market conditions. The ultimate number of performance units that can be earned can range from 0% to 150%200% of target depending on performance relative to target over the applicable period. The shares earned will vest on the third or fourth anniversary of the date of grant.grant. The Company'sCompany’s shares available for grant have been reduced to reflect the shares that could be earned at 150% ofthe maximum target.
During the third quarter of 2017, the Company granted performance unit awards to a Company executive officer with vesting subject to the achievement of certain performance and market conditions. The ultimate number of performance units that can be earned can range from 0% to 150% of target depending on performance relative to target over the applicable period. The shares that will become eligible to vest will be measured over a three-year period ending on December 31, 2019, unless the performance period is shortened because of a change of control of the Company or a termination of the executive officer’s employment without cause. The Company's shares available for grant have been reduced to reflect the shares that could be earned at 150% of target. The fair value of the market condition of these performance units was calculated, on its respective grant date, using a binomial valuation model, which estimates the potential outcome of reaching the market condition based on simulated future stock prices. The stock-based compensation expense related to these awards will be recorded over the respective requisite service period of approximately 2.4 years. During the three months ended September 30, 2017, the achievement of the performance condition for these performance units was considered probable, and as a result, the Company recognized an immaterial amount of stock-based compensation expense related to these performance unit awards.
During the three and nine months ended September 30, 2017, the Company recorded $1.2 million and $3.1 million, respectively, of stock-based compensation expense related to all outstanding nonvested performance unit awards. During the

three and nine months ended September 30, 2016, the Company recorded $0.7 million and $2.0 million, respectively, of stock-based compensation expense related to all outstanding nonvested performance unit awards.
For the three and nine months ended September 30, 2017,2023, the Company recorded stock-based compensation expense of approximately $5.9$9.5 million and $16.7$32.9 million, respectively, primarily related to all outstanding nonvested equity stock grants. For the three and nine months ended September 30, 2016,2022, the Company recorded stock-based compensation expense of approximately $4.1$8.5 million and $10.9$24.0 million, respectively, related to all outstanding nonvested equity stock grants.
Unrecognized stock-based compensation related to all nonvested equity stock grants, net of estimated forfeitures, was approximately $46.4$73.0 million at September 30, 2017.2023. This amount is expected to be recognized over a weighted averageweighted-average period of 2.52.1 years.

On May 1, 2017,August 10, 2023, the Company initiatedentered into an accelerated share repurchase program with BarclaysRoyal Bank PLC.of Canada (“RBC”) (the “2023 ASR Program”). The accelerated share repurchase program is2023 ASR Program was part of the broader share repurchase program previously authorized by the Company's Board on January 21, 2015.October 29, 2020. Under the accelerated share repurchase program,2023 ASR Program, the Company pre-paid to Barclays Bank PLC,RBC the $50.0$100.0 million purchase price for its common stock and, in turn, the Company received an initial delivery of approximately 3.21.6 million shares of its common stock from Barclays Bank PLC, in the second quarter of 2017,RBC on August 11, 2023, which were retired and recorded as a $40.0an $80.0 million reduction to stockholders'stockholders’ equity.

Excise tax incurred is included in the cost of shares to be ultimately purchasedrepurchased in the Unaudited Condensed Consolidated Statements of Stockholders’ Equity.
On September 9, 2022, the Company entered into an accelerated share repurchase program with Wells Fargo Bank, National Association (“Wells Fargo”) (the “2022 ASR Program”). The 2022 ASR Program was part of the share repurchase program previously authorized by the Board on October 29, 2020.

The Company records stockshare repurchases as a reduction to stockholders’ equity. The Company records a portion of the purchase price of the repurchased shares as an increase to accumulated deficit when the price of the shares repurchased exceeds the average original proceeds per share received from the issuance of common stock. During the nine months ended September 30, 2017, the cumulative price of $29.4 million was recorded as an increase to accumulated deficit.stock in accordance with its accounting policy.


12.13. Income Taxes
The Company recorded a provision for income taxes of $6.2$4.0 million and $4.3$2.5 million for the three months ended September 30, 20172023 and 2016,2022, respectively, and $16.1a provision for (benefit from) income taxes of $(151.1) million and $14.9$5.9 million for the nine months ended September 30, 20172023 and 2016,2022, respectively. The provision for income taxes for the three months ended September 30, 2023 was primarily driven by foreign withholding taxes and adjustments to the valuation allowance release on U.S. deferred tax assets due to a change in forecasted taxable income and expense, offset by tax benefits from excess stock-based compensation deductions. The benefit from income taxes for the nine months ended September 30, 2023 was primarily driven by the valuation allowance release on U.S. deferred tax assets, as well as tax benefits from excess stock-based compensation deductions, offset by foreign withholding taxes. The provision for income taxes for the three and nine months ended September 30, 2017 is primarily comprised2022 was driven by a combination of

the Company'svaluation allowance recorded on U.S. federal, state anddeferred tax assets, foreign withholding taxes, and incomethe statutory tax expense recognized from exercises and expiration of out-of-the-money fully vested shares from equity incentive plans. Similarly, the income taxes for the threeforeign jurisdictions for 2022 and nineindefinite-lived intangible tax amortization expense.
During the three months ended September 30, 2016 was primarily comprised of the Company's U.S. federal, state2023 and foreign taxes and income tax expense recognized from exercises and expiration of shares from equity incentive plans.
During the three and nine months ended September 30, 2017,2022, the Company paid withholding taxes of $4.7$5.4 million and $15.6$5.5 million, respectively. During both the three and nine months ended September 30, 2016,2023 and 2022, the Company paid withholding taxes of $5.5 million and $16.5 million, respectively.
As of September 30, 2017, the Company’s unaudited condensed consolidated balance sheets included net deferred tax assets, before valuation allowance, of approximately $225.0 million, which consists of net operating loss carryovers, tax credit carryovers, amortization, employee stock-based compensation expenses and certain liabilities, partially reduced by deferred tax liabilities associated with the convertible notes.$15.8 million.
The Company has U.S. federal deferred tax assets related to research and development credits, foreign tax credits and other tax attributes that can be used to offset federal taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. As of September 30, 2017, the Company determined that there is sufficient positive evidence to conclude that it is more likely than not sufficient taxable income will exist in the future allowing the Company to recognize these deferred tax assets. It is possible that some or all these attributes could ultimately expire unused. If facts and circumstances change in the future, the Company may determine at that time a valuation allowance is necessary. A valuation allowance would materially increase the Company's tax expense in the period applied and would adversely affect its results of operations and statements of financial condition. Changes in the Company's underlying facts or circumstances, such as the impact of the acquisitions, will be continually assessed and the Company will re-evaluate its position accordingly.
As of September 30, 2017, the Company continues to maintain a valuation allowance against the majority of its state deferred tax assets. Management periodically evaluates the realizability of the Company'sits net deferred tax assets based on all available evidence, both positive and negative. The realizability of the Company'sCompany’s net deferred tax assets is dependent on its ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. During the second quarter of 2023, based on all available positive and negative evidence, the Company determined that it was appropriate to release the valuation allowance on the majority of the Company’s U.S. federal and other state deferred tax assets. The Company continuesrecognized a $149.4 million discrete tax benefit during the three and six months ended June 30, 2023 as a result of the valuation allowance release.
During the second quarter of 2023, the Company reached a cumulative income position over the previous three years. The cumulative three-year income is considered positive evidence, which is considered objective and verifiable, and thus received significant weighting. Additional positive evidence considered by the Company in its assessment included recent utilization of tax attribute carryforwards and future forecasts of continued profitability in the United States. Negative evidence the Company
23


considered included economic uncertainties, including volatility of the industry, and the possibility of a recession or a decline in the market.
Upon considering the relative impact of all evidence during the second quarter of 2023, both negative and positive, and the weight accorded to maintain aeach, the Company concluded that it was more likely than not that the majority of its deferred tax assetassets would be realizable, with the exception of primarily its California research and development credits and certain expiring federal tax credits that have not met the “more likely than not” realization threshold criteria. As a result, the Company released the related valuation allowance against the majority of $29.0 millionits federal and state deferred tax assets. The effect of the valuation allowance release is included as a component of the benefit from income taxes in the accompanying Unaudited Condensed Consolidated Statement of Operations.
When a change in valuation allowance is recognized during an interim period, the change in valuation allowance resulting from current year income is included in the annual effective tax rate and the release of valuation allowance supported by projections of future taxable income is recorded as a discrete provision for (benefit from) income taxes in the interim period. During the three months ended September 30, 2017.2023, the Company further adjusted its valuation allowance release as a result of a change in forecasted income and tax expense, primarily due to the sale of intangible assets as part of the PHY IP group divestiture. The Company recognized discrete tax expense of $4.4 million during the three months ended September 30, 2023, and it recognized a $145.1 million discrete tax benefit during the nine months ended September 30, 2023, as a result of the valuation allowance release.
The Company has U.S. federal deferred tax assets related to research and development credits, foreign tax credits and other tax attributes that can be used to offset U.S. federal taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. It is possible that some or all of these attributes could ultimately expire unused.
The Company maintains liabilities for uncertain tax positions within its long-term income taxes payable accounts and as a reduction to existing deferred tax assets to the extent tax attributes are available to offset such liabilities. These liabilities involve judgment and estimation and are monitored by management based on the best information available including changes in tax regulations, the outcome of relevant court cases and other information.
As of September 30, 2017,December 31, 2022, the Company had approximately $22.9$164.5 million of unrecognized tax benefits including $20.7$19.6 million recorded as a reduction of long-term deferred tax assets, $143.6 million recorded as a reduction of other assets associated with refundable withholding taxes previously withheld from licensees in South Korea, and $2.2$1.3 million in recorded to long-term income taxes payable. If recognized, approximately $2.2 million would be recorded as an income tax benefit. As of December 31, 2016,September 30, 2023, the Company had $21.9approximately $179.5 million of unrecognized tax benefits, including $19.7$27.4 million recorded as a reduction of long-term deferred tax assets, $75.1 million recorded as a reduction of other assets associated with refundable withholding taxes previously withheld from licensees in South Korea and $2.2$77.0 million recorded in long-term income taxes payable. The decrease in the unrecognized tax benefits recorded as a reduction of other assets from December 31, 2022 to September 30, 2023, is due to the Company’s determination in the three months ended September 30, 2023, that it is more likely than not to succeed in its decision to request refund of Korean withholding tax for which refund claims were submitted in October 2023. The increase in unrecognized tax benefits recorded to long-term income taxes payable from December 31, 2022 to September 30, 2023 is primarily due to the Company’s decision to request refund of Korean withholding tax for which the Company claimed foreign tax credits in the United States. As a result of an analysis of court rulings and other settlement activities to date in South Korea, the Company has determined that it may be entitled to refund claims for foreign taxes previously withheld by licensees in South Korea. If the Company is successful in recovering the $152.6 million of refundable withholding taxes from South Korea, the refund will result in an offsetting reduction in U.S. foreign tax credits. The Company recognizes there are numerous risks and uncertainties associated with the ultimate collection of this refund. The Company previously maintained an offsetting reserve for the entire amount of refundable withholding taxes previously withheld in South Korea. During the three months ended September 30, 2023, the Company concluded it is more likely than not it will recover withholding taxes withheld during the past five years and accordingly filed a claim in October 2023 for refund of certain refundable withholding taxes, and recorded an income taxes receivable of $82.7 million with an offsetting long-term income taxes payable of $75.6 million and a reduction in long-term deferred tax assets of $7.1 million. The Company has not recorded a receivable for the portion of potentially available refunds for which a claim for refund has not been submitted or the Company does not intend to pursue at this time, as the Company does not at this time believe recovery of those taxes would be more likely than not if a refund claim were submitted. The Company continues to evaluate the potential for recovery of these taxes.
Although it is possible that some of the unrecognized tax benefits could be settled within the next 12 months, the Company cannot reasonably estimate the outcome at this time.
The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision. At September 30, 2017 and December 31, 2016, an immaterial amount of interest and penalties is included in long-term income taxes payable.
Rambus files income tax returns for the U.S., California, India, the U.K., the Netherlands and various other state and foreign jurisdictions. The U.S. federal returns are subject to examination from 2014 and forward. The California returns are subject to examination from 2010 and forward. In addition, any research and development credit carryforward or net operating loss carryforward generated in prior years and utilized in these or future years may also be subject to examination. The India returns are subject to examination from fiscal year ending March 2012 and forward. The Company is currently under examination by California for the 2010 and 2011 tax years and New York for the 2013, 2014 and 2015 tax years. The Company’s India subsidiary is under examination by the Indian tax administration for tax years beginning with 2011, except for 2014, which was assessed in the Company's favor. These examinations may result in proposed adjustments to the income taxes as filed during these periods. Management regularly assesses the likelihood of outcomes resulting from income tax examinations to determine the adequacy of their provision for income taxes and believes their provision for unrecognized tax benefits is adequate.
Additionally, the Company'sCompany’s future effective tax rates could be adversely affected by earnings being higher than anticipated in countries where the Company has higher statutory rates or lower than anticipated in countries where it has lower statutory rates, by changes in valuation of its deferred tax assets and liabilities or by changes in tax laws or interpretations of those laws.

14. Litigation and Asserted Claims
Rambus is not currently a party to any material pending legal proceeding; however, from time to time, Rambus may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on ourits business, operating results, financial position or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management attention and resources and other factors.

The Company records a contingent liability when it is probable that a loss has been incurred and the amount is reasonably estimable in accordance with accounting for contingencies.


15. Derivative Instruments and Hedging Activities
In the first quarter of 2023, the Company began using foreign currency forward contracts (the “Contracts”) to manage the Company’s exposure related to certain foreign currency denominated monetary assets (the “Hedging Program”) and to minimize the related impact of foreign currency fluctuations on the Company’s earnings. The hedged monetary assets primarily consist of certain euro-denominated cash and accounts receivable balances. The Contracts mitigate the Company’s foreign currency exposure when the Contracts are settled at their maturity by generally offsetting the gains and losses generated by the re-measurement of the underlying monetary assets.
The Contracts are entered into at the end of each month and have a duration of approximately one month at inception. Due to the short duration of these Contracts, their fair value is deemed immaterial. As the Contracts are considered derivative instruments that are not designated and do not qualify as hedging instruments, any gains and losses resulting from changes in their fair value are recorded to interest income and other income (expense), net on the Company’s Unaudited Condensed Consolidated Statements of Operations. The Company does not use its Hedging Program for speculative or trading purposes.
The Contract outstanding as of September 30, 2023 was entered into by the Company on the last business day of the period. Given the relatively short duration such contracts are outstanding in relation to changes in potential market rates, the change in the fair value was deemed immaterial.
As of September 30, 2023, the total local currency amount of the outstanding Contract was €3.2 million, and its total notional value was $3.4 million. For the three and nine months ended September 30, 2023, any gains and losses resulting from changes in fair value of the Company’s Contracts were deemed immaterial.

16. Restructuring and Other Charges
2023 Restructuring Plan
In June 2023, the Company initiated a restructuring program to reduce overall expenses, which is expected to improve future profitability by reducing the Company’s overall spending (the “2023 Restructuring Plan”). In connection with this restructuring program, the Company initiated a plan resulting in a reduction of 42 employees. During the nine months ended September 30, 2023, the Company recorded charges of approximately $9.4 million to “Restructuring and other charges” in its Unaudited Condensed Consolidated Statement of Operations, related to the reduction in workforce, as well as write-downs of obligations related to certain IP development costs and software licenses for engineering development tools. The 2023 Restructuring Plan is expected to be substantially completed in the fourth quarter of 2023.
The following table summarizes the 2023 Plan restructuring activities during the nine months ended September 30, 2023:

During the nine months ended September 30, 2022, the Company did not initiate any restructuring programs.

17. Divestiture
In July 2023, the Company entered into an asset purchase agreement (the “Purchase Agreement”) with Cadence Design Systems, Inc. (the “Purchaser”), pursuant to which the Company agreed to sell certain assets and the Purchaser agreed to assume certain liabilities from the Company, in each case with respect to the Company’s PHY IP group, for $110.0 million in cash, subject to certain adjustments and certain closing conditions (the “Transaction”). The decision to sell this business reflects the evolution of the Company’s core semiconductor business to focus on the development of digital IP and chips, including novel memory solutions for high-performance computing, to support the continued advancement of the data center and artificial intelligence.
The Transaction was completed on September 6, 2023 and resulted in net proceeds of approximately $106.3 million, which consisted of the initial selling price of $110.0 million offset by approximately $3.7 million related to certain purchase price adjustments. The Company recognized a net gain on divestiture of the PHY IP group in the Unaudited Condensed Consolidated Statements of Operations of approximately $90.8 million during the three and nine months ended September 30, 2023. Transaction costs of approximately $1.4 million were included in the net gain of $90.8 million.
The divestiture of the PHY IP group did not represent a strategic shift that would have a major effect on the Company’s consolidated results of operations, and therefore its results of operations were not reported as discontinued operations.
Concurrent with the Transaction, the Company also recorded a charge of approximately $10.0 million in the Company’s Unaudited Condensed Consolidated Statements of Operations. The charge was primarily related to the accelerated amortization of software licenses that were not part of the PHY IP disposal group.

18. Acquisition
Therewere no acquisitions during the nine months ended September 30, 2023.
2022 Acquisition
Hardent, Inc.
On May 20, 2022, (the “Closing Date”), the Company completed its acquisition of Hardent, a leading electronic design company, by acquiring all of its outstanding shares. The Company acquired Hardent for a total consideration of approximately $16.1 million, which consisted of $14.7 million in initial cash consideration paid at the Closing Date, $1.2 million deposited into an escrow account to fund indemnification obligations to be released within 18 months after the Closing Date, and $0.2 million deposited into an escrow account to fund other contractual provisions related to certain working capital adjustments. The addition of the technology and expertise from Hardent augments the Company’s CXL memory interconnect initiative.
As part of the acquisition, the Company agreed to pay certain Hardent employees approximately $1.2 million in cash over three years following the Closing Date (the “Retention Bonus”), to be paid in three equal installments on each of the dates that are 12 months, 24 months and 36 months following the Closing Date. The Retention Bonus payouts are subject to the condition of continued employment, therefore the Retention Bonus payouts will be treated as compensation and will be expensed ratably over the retention period.
The fair value of the intangible assets acquired was determined by management primarily by using the multi-period excess earnings method under the income approach. This method reflects the present value of the projected cash flows that are expected to be generated by the existing technologies less charges representing the contribution of other assets to those cash
26


flows. The fair values of the remaining assets acquired and liabilities assumed approximated their carrying values at the Closing Date. The Company performed a valuation of the net assets acquired as of the Closing Date.
The total consideration from the acquisition was allocated as of the Closing Date, and reflects adjustments made during the measurement period, as follows:

Our strategy is to continue to augment our patent license business model to provide additional technology, products and services while creating and leveraging strategic synergies to increase revenue. In supportinto server memory modules. Product revenue accounted for 50% of our strategy, we acquired four businesses in 2016 in the fields of mobile payments, smart ticketing, memory buffer chips and SerDes IP cores. On January 25, 2016, our Security division completed the acquisition of Smart Card Software, Ltd. (“SCS”), a privately-held company incorporated in the United Kingdom,consolidated revenue for a pound sterling equivalent of $104.7 million in cash. Through this purchase we acquired two complementary businesses: Bell Identification Ltd., a leader in mobile payments, and Ecebs Ltd., a leading supplier of smart ticketing systems. We believe these businesses complement our security division by allowing us to extend our foundational security technology to offer differentiated, value-added security solutions to our customers.

On August 4, 2016, our Memory and Interfaces division completed the acquisition of all the assets of Inphi’s Memory Interconnect Business for $90 million in cash. The acquisition included product inventory, customer contracts, supply chain agreements and intellectual property. On August 5, 2016, our Memory and Interfaces division completed the acquisitioneach of the assets of Semtech Corporation’s Snowbush IP group for $32 million in cash. Snowbush IP, formerly part of Semtech’s Systems Innovation Group, is a provider of silicon-proven, high-performance serial link solutions. We believe these acquisitions strengthen our market position for memory buffer chip productsthree and bolster our SerDes and IP offerings enabling us to better address the needs of the server, networking and data center market.

The vast majority of our patents were secured throughoriginate from our internal research and development efforts across allefforts. Additionally, from time to time, we enter into agreements to sell certain patent assets under agreements which may also include subsequent profit-sharing. The sale of these patents, as well as the subsequent profit-sharing, are included as part of our business units. Royaltiesroyalty revenue. Revenue from patent licensesroyalties accounted for 68%27% and 67%29% of our consolidated revenue for the three and nine months ended September 30, 2017, respectively,2023, as compared to 70%27% and 76%33% for the three and nine months ended September 30, 2016, respectively.2022.

We also offer our customers technology licenses to support the implementation and adoption of our technology in their products or services. Our customers include leading companies such as Eaton, GE, IBM, Panasonic, Qualcomm, Samsung, Sony and Toshiba. Our technology license offerings include a range of technologies for incorporation into our customers’ products and systems. We also offer a range of services as part of our technology licenses which can include know-how and technology transfer, product design and development, system integration, and other services. These technology license agreements may have both a fixed price (non-recurring) component and ongoing use fees and in some cases, royalties. Further, under technology licenses, our customers typically receive licenses to our patents necessary to implement these solutions in their products with specific rights and restrictions to the applicable patents elaborated in their individual contracts with us. Royalties from technology licenses accounted for 6% of our consolidated revenue for both the three and nine months ended September 30, 2017, as well as for the three and nine months ended September 30, 2016.

The remainder of our revenue is product revenue, contract servicesContract and other revenue consists primarily of Silicon IP, which includesis comprised of our product sales,high-speed interface and security IP. Revenue sources under contract and other include our IP core licenses, software licenses and related implementation, support and maintenance fees and engineering services fees. The timing and amounts invoiced to customers can vary significantly depending on specific contract terms and can therefore have a significant impact on deferred revenue or account receivablesaccounts receivable in any given period.

Intellectual Property

As of September 30, 2017,2023, our semiconductor, lighting, security, and other technologies are covered by 2,0882,215 U.S. and foreign patents. Additionally, we have 589546 patent applications pending. Some of the patents and pending patent applications are derived
29


from a common parent patent application or are foreign counterpart patent applications. We have a program to file applications for and obtain patents in the United States and in selected foreign countries where we believe filing for such protection is appropriate and would further our overall business strategy and objectives. In some instances, obtaining appropriate levels of protection may involve prosecuting continuation and counterpart patent applications based on a common parent application. We believe our patented innovations provide our customers with the ability to achieve improved performance, lower risk, greater cost-effectiveness, and other benefits in their products and services.


Trends
There are a number of trends that may have a material impact on us in the future, including but not limited to, the evolution of memory and SerDes technology, adoption of mobile payment, smart ticketing and security solutions, adoption of LEDs in edge-lit general lighting, the use and adoption of our inventions or technologies generally, industry consolidation and global economic conditions with the resulting impact on sales of consumer electronic systems.
We have a high degree of revenue concentration. Our top five customers for each reporting period represented approximately 57%63% and 56%59% of our revenue for the three and nine months ended September 30, 2017, respectively,2023, as compared to 59%61% and 65%57% for the three and nine months ended September 30, 2016,2022, respectively. For the three and nine months ended September 30, 2017, and for the three and nine months ended September 30, 2016, revenue from Micron, Samsung and SK hynix each accounted for 10% or more of our total revenue. While we expect Samsung, SK hynix and Micron to account for a significant portion of our ongoing licensing revenue, theThe particular customers which account for revenue concentration have varied from period-to-period as a result of the addition of new contracts, expiration of existing contracts, renewals of existing contracts, industry consolidation and the volumes and prices at which the customers have recently sold to their customers. These variations are expected to continue in the foreseeable future.
Our revenue from companies headquartered outside of the United States accounted for approximately 56%69% and 58%61% of our total revenue for the three and nine months ended September 30, 2017, respectively,2023, as compared to 63%37% and 65%42% for the three and nine months ended September 30, 2016.2022. We expect that revenue derived from international customers will continue to represent a significant portion of our total revenue in the future. To date, the majority of theCurrently, our revenue from international customers has beenis predominantly denominated in U.S. dollars. However, to the extent that such customers’ sales to their customers are not denominated in U.S. dollars, any revenue that we receive as a result of such sales could be subject to fluctuations in currency exchange rates. In addition, if the effective price of licensed products sold by our foreign customers were to increase as a result of fluctuations in the exchange rate of the relevant currencies, demand for licensed products could fall, which in turn would reduce our revenue. We do not use financial instruments to hedge foreign exchange rate risk. For additional information concerning international revenue, seerefer to Note 5, “Segments and Major Customers,” of Notes to Unaudited Condensed Consolidated Financial Statements of this Form 10-Q.
Our licensing cycle for new licensees as well as renewals for existing licensees is lengthy, costly and unpredictable without any degree of certainty. We may incur costs in any particular period before any associated revenue stream begins, if at all. Our lengthy license negotiation cycles could make our future revenue difficult to predict because we may not be successful in entering into licenses with our customers in the amounts projected, or on our anticipated timelines.
The semiconductor industry is intensely competitive and highly cyclical, limiting our visibility with respect to future sales. To the extent that macroeconomic fluctuations negatively affect our principal customers, the demand for our products and

technology may be significantly and adversely impacted and we may experience substantial period-to-period fluctuations in our operating results.
The royalties we receive from our semiconductor customers are partly a function of the adoption of our technologies by system companies. Many system companies purchase semiconductors containing our technologies from our customers and do not have a direct contractual relationship with us. Our customers generally do not provide us with details as to the identity or volume of licensed semiconductors purchased by particular system companies. As a result, we face difficulty in analyzing the extent to which our future revenue will be dependent upon particular system companies.
Global demand for effective security technologies continues to increase. In particular, highly integrated devices such as smart phones are increasingly used for applications requiring security such as mobile payments, corporate information and user data. Our RSD operating segment is primarily focused on positioning its DPA countermeasures, CryptoMedia™, CryptoFirewall™ and CryptoManager™ technology solutions, and the introduction Several of in-field applications mobile payments and smart ticketing solutions to our offerings to capitalize on these trends and growing adoption among technology partners and customers.
Engineering costs as well as sales, general and administrative expenses in the aggregate increased and cost of product revenue in the aggregate decreased in the third quarter of 2017 as compared to the same period in 2016. Cost of product revenue, engineering costs as well as sales, general and administrative expenses as a percentage of revenue decreasedlicensees have renewed or extended their license agreements with us during the nine months ended September 30, 2017 as compared to the same period in 2016. Cost of product revenue, engineering costs as well as sales, general2023, including SK hynix and administrative expenses in the aggregate increased during the nine months ended September 30, 2017 as compared to the same period in 2016. Cost of product revenue and engineering costs as a percentage of revenue increased and sales, general and administrative expenses as a percentage of revenue decreased during the nine months ended September 30, 2017 as compared to the same period in 2016. In the near term, we expect these costs in the aggregate to be higher as we intend to continue to make investments in the infrastructure and technologies required to increase our product innovation in semiconductor, security, mobile payments, smart cards and other technologies. In addition, while we have not been involved in material litigation since 2014, to the extent litigation is again necessary, our expectations on the amount and timing of any future general and administrative costs are uncertain.Socionext.
As a part of our overall business strategy, from time to time, we evaluate businesses and technologies for potential acquisitionacquisitions that are aligned with our core business and designed to supplement our growth, including the acquisition of Hardent in the second quarter of 2022 and the acquisitions of SCS,AnalogX and PLDA in the assetsthird quarter of the Snowbush IP group and the Memory Interconnect Business.2021. Similarly, we evaluate our current businesses and technologies that are not aligned with our core business for potential divestiture.
In May 2014,divestiture, such as the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“Standard”). The Standard, as amended, is effective for us on January 1, 2018. We have yetsale of our PHY IP group to make a final decision regardingCadence in the adoption method we will use, but we believe we will adopt the Standard on a full retrospective basis, with a cumulative-effect adjustment to the opening balancethird quarter of retained earnings on January 1, 2016 determined on the basis of the impact of the Standard on the accounting for contracts that are not completed as of that date. Although we have yet to finalize our evaluation and quantification of the effects that the Standard will have on our consolidated financial statements, and to finalize the design and implementation of related changes to our policies, procedures and controls, we expect the Standard to materially impact the timing of revenue recognition for our fixed-fee intellectual property (IP) licensing arrangements (including certain fixed-fee agreements that license our existing IP portfolio as well as IP added to our portfolio during the license term) as a majority of such revenue would be recognized at inception of the license term, as opposed to over time as is the case under current U.S. GAAP, and we will be required to compute and recognize interest income over time as control over the IP generally transfers significantly in advance of cash being received from customers. We are also evaluating the form and content of any guidance that we may provide following implementation of the Standard and expect our guidance metrics to change.2023. We expect that any change to current revenue recognition practices may significantly increase volatility incontinue to evaluate and potentially enter into strategic acquisitions or divestitures which will impact our quarterly revenue trends.business and operating results.

The provision for income taxes for the three months ended September 30, 2023 was primarily driven by foreign withholding taxes and adjustments to the valuation allowance release on our U.S. deferred tax assets due to a change in our forecasted taxable income and expense, offset by tax benefits from excess stock-based compensation deductions. The benefit from income taxes for the nine months ended September 30, 2023 was primarily driven by the valuation allowance release on our U.S. deferred tax assets, as well as tax benefits from excess stock-based compensation deductions, offset by foreign withholding taxes. Our income tax provision for the three months ended September 30, 2023 and income tax benefit for the nine months ended September 30, 2023 reflected an effective tax rate of 3.8% and (121.6)%, respectively. Our income tax provision for the three and nine months ended September 30, 2022 reflected an effective tax rate of 72.7% and (24.5)%, respectively. Our effective tax rate for the three and nine months ended September 30, 2017 was different2023 differed from the U.S. statutory tax rate primarily due to incomethe valuation allowance release on our U.S. deferred tax expense recognized from exercises and expiration of out-of-the-money fully vested shares from our equity incentive plans. Similarly, the effective tax rate was lower for the three and nine months ended September 30, 2017 as compared to the same period in 2016, due to higher income tax expense recognized from exercises and expiration of vested shares from our equity incentive plans in 2016.
We recorded a provision for income taxes of $6.2 million and $4.3 million for the three months ended September 30, 2017 and 2016, respectively. We recorded a provision for income taxes of $16.1 million and $14.9 million for the nine months ended September 30, 2017 and 2016, respectively. During the three months ended September 30, 2017 and 2016, we paid withholding taxes of $4.7 million and $5.5 million, respectively. During the nine months ended September 30, 2017 and 2016, we paid withholding taxes of $15.6 million and $16.5 million, respectively.

We have U.S. federal deferred tax assets related to research and development credits, foreign tax credits and other tax attributes that can be used to offset federal taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. As of September 30, 2017, we determined that there is sufficient positive evidence to conclude that it is more likely than not sufficient taxable income will exist in the future allowing us to recognize these deferred tax assets. It is possible that some or all these attributes could ultimately expire unused. If facts and circumstances change in the future, we may determine at that time a valuation allowance is necessary. A valuation allowance would materially increase our tax expense in the period applied and would adversely affect our results of operations and statement of financial condition. Changes in our underlying facts or circumstances, such as the impact of the acquisitions, will be continually assessed and we will re-evaluate our position accordingly.
As of September 30, 2017, we continue to maintain afull valuation allowance against the majority of our stateU.S. deferred tax assets.
During the three months ended September 30, 2023 and 2022, we paid withholding taxes of $5.4 million and $5.5 million, respectively. During both the nine months ended September 30, 2023 and 2022, we paid withholding taxes of $15.8 million.
We periodically evaluate the realizability of our net deferred tax assets based on all available evidence, both positive and

negative. The realizability of our net deferred tax assets is dependent on our ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. During the second quarter of 2023, based on all available positive and negative evidence, we determined that it was appropriate to release the valuation allowance on the majority of our U.S. federal and other state deferred tax assets. We recognized a $149.4 million discrete tax benefit during the three and six months ended June 30, 2023 as a result of the valuation allowance release.

During the second quarter of 2023, we reached a cumulative income position over the previous three years. The cumulative three-year income is considered positive evidence, which is considered objective and verifiable, and thus received significant weighting. Additional positive evidence considered by us in our assessment included recent utilization of tax attribute carryforwards and future forecasts of continued profitability in the United States. Negative evidence we considered included economic uncertainties, including volatility of the industry, and the possibility of a recession or a decline in the market.

Upon considering the relative impact of all evidence during the second quarter of 2023, both negative and positive, and the weight accorded to each, we concluded that it was more likely than not that the majority of our deferred tax assets would be realizable, with the exception of primarily our California research and development credits and certain expiring federal tax credits that have not met the “more likely than not” realization threshold criteria. As a result, we released the related valuation allowance against the majority of our federal and state deferred tax assets. The effect of the valuation allowance release is included as a component of the benefit from income taxes in the accompanying Unaudited Condensed Consolidated Statements of Operations of this Form 10-Q.

When a change in valuation allowance is recognized during an interim period, the change in valuation allowance resulting from current year income is included in the annual effective tax rate and the release of valuation allowance supported by projections of future taxable income is recorded as a discrete provision for (benefit from) income taxes in the interim period. During the three months ended September 30, 2023, we further adjusted our valuation allowance release as a result of a change in our forecasted income and tax expense, primarily due to the sale of intangible assets as part of our PHY IP group divestiture. We recognized discrete tax expense of $4.4 million during the three months ended September 30, 2023, and we recognized a $145.1 million discrete tax benefit during the nine months ended September 30, 2023, as a result of our valuation allowance release.
We have U.S. federal deferred tax assets related to research and development credits, foreign tax credits and other tax attributes that can be used to offset U.S. federal taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. It is possible that some or all of these attributes could ultimately expire unused.

Critical Accounting Policies and Estimates
The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements,Unaudited Condensed Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, investments, income taxes, litigation and other contingencies. We base our estimates on historical experience and on various other assumptions that are believed 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 under different assumptions or conditions. Our critical accounting estimates include those regarding (1) revenue recognition, (2) goodwill, (3) intangible assets, (4) income taxes, and (5) stock-based compensation.compensation and (6) business combinations. For a discussion of our critical accounting estimates, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2016.2022.

Item 3. Quantitative and Qualitative Disclosures aboutAbout Market Risk
We are exposed to financial market risks, primarily arising from the effect of interest rate fluctuations on our investment portfolio. Interest rate fluctuation may arise from changes in the market’s view of the quality of the security issuer, the overall economic outlook, and the time to maturity of our portfolio. We mitigate this risk by investing only in high quality, highly liquid instruments. Securities with original maturities of one year or less must be rated by two of the three industry standard rating agencies as follows: A1 by Standard & Poor’s, P1 by Moody’s and/or F-1 by Fitch. Securities with original maturities of greater than one year must be rated by two of the following industry standard rating agencies as follows: AA- by Standard & Poor’s, Aa3 by Moody’s and/or AA- by Fitch. By corporate investment policy, we limit the amount of exposure to $15.0 million or 10% of the portfolio, whichever is lower, for any single non-U.S. Government issuer. A single U.S. Agency can represent up to 25% of the portfolio. No more than 20% of the total portfolio may be invested in the securities of an industry sector, with money market fund investments evaluated separately. Our policy requires that at least 10% of the portfolio be in securities with a maturity of 90 days or less. We may make investments in time deposits, U.S. Treasuries, U.S. Agencies,government-sponsored obligations, and corporate notes, bonds and municipal bonds and notescommercial paper with maturities up to 36 months. However, thewe bias of our investment portfolio isto shorter maturities. AllThe majority of our investments must beare U.S. dollar denominated. Additionally, we have no significant exposure to European sovereign debt.
We invest our cash equivalents and marketable securities in a variety of U.S. dollar financial instruments such as U.S. Treasuries, U.S. Government Agencies, commercial paper and corporate notes. Our policy specifically prohibits trading securities for the sole purposespurpose of realizing trading profits. However, we may liquidate a portion of our portfolio if we experience unforeseen liquidity requirements. In such a case, if the environment has been one of rising interest rates, we may experience a realized loss, similarly, if the environment has been one of declining interest rates, we may experience a realized gain. As of September 30, 2017,2023, we had an investment portfolio of fixed income marketable securities of $142.3$287.8 million, including cash equivalents.equivalents and time deposits. If market interest rates were to increase immediatelyimmediately and uniformly by 1.0% from the levels as of September 30, 2017,2023, the fair value of the portfolio would decline by approximately $0.1 million. $1.0 million. Actual results may differ materially from this sensitivity analysis.
The fair value of our convertible notes is subject to interest rate risk, market risk and other factors due to the convertible feature. The fair value of the convertible notes will generally increase as interest rates fall and decrease as interest rates rise. In addition, the fair value of the convertible notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines in value. The interest and market value changes affect the fair value of our convertible notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligation.
We invoice the majority of our customers in U.S. dollars. Although the fluctuation of currency exchange rates may impact our customers, and thus indirectly impact us, we do not attempt to hedge this indirect and speculative risk.risk, other than as noted in the paragraph below. Our overseas operations consist primarily of international business operations in France, the Netherlands and the United Kingdom, design centers in Canada, India, Bulgaria and Finland and small business development offices in Australia, China, Japan, South Korea Singapore and Taiwan. We monitor our foreign currency exposure; however,exposure and, as disclosed below, we have entered into foreign currency forward contracts to partially mitigate the exposure in currencies where we believe this is appropriate.
Since the first quarter of 2023, we enter into foreign currency forward contracts (the “Contracts”) to manage our exposure related to certain foreign currency denominated monetary assets (the “Hedging Program”) and to minimize the related impact of foreign currency fluctuations on our earnings. The hedged monetary assets primarily consist of certain euro-denominated cash and accounts receivable balances. We enter into Contracts at the end of each month, and they have a duration of approximately one month at inception. As of September 30, 2023, the total local currency amount of the outstanding Contract was €3.2 million, and its total notional value was $3.4 million. Given the short duration such contracts are outstanding in relation to changes in potential market rates, the change in their fair value was deemed immaterial and was not reflected either as an asset or a liability in the accompanying Unaudited Condensed Consolidated Balance Sheet of this Form 10-Q. Additionally, the effect of a hypothetical 1% change in the euro as compared to the U.S. dollar as of September 30, 2017, we believe2023 would not have a material impact on our financial statements as the effect of foreign currency exposurerate changes on our Contracts is not material enoughexpected to warrantoffset the effect of foreign currency hedging.rate changes on the hedged items. Actual results may differ materially from this sensitivity analysis.

Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in the reports we file or submit pursuant to the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2017,2023, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting (as definedidentified in management’s evaluation pursuant to Rules 13a-15(f) and 15d-15(f)13a-15(d) or 15d-15(d) of the Exchange Act)Act during the quarter ended September 30, 2017,2023, that have materially affected, or that we believe are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION


Item 1. Legal Proceedings
We are not currently a party to any material pending legal proceeding; however, from time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business, operating results, financial position or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management attention and resources and other factors.

Item 1A. Risk Factors
Because of the following factors, as well as other variables affecting our operating results, past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. See also “Note Regarding Forward-Looking Statements” at the beginning of this report.

Summary Risk Factors
Risks Associated With Our Business, Industrybusiness is subject to numerous risks and Market Conditionsuncertainties that you should consider before investing in our company, as fully described below. The principal factors and uncertainties that make investing in our company risky include, among others:
The successWe have traditionally operated in, and may enter other, industries that are highly cyclical and competitive.
Much of our revenue is concentrated in a few customers, and if we lose any of these customers through contract terminations, acquisitions, or other means, our revenue may decrease substantially.
Products that fail to meet their specifications or are defective could impose significant costs on us or loss of business.
If we do not keep pace with technological innovations or customers’ increasing technological requirements, we may not be able to enhance our existing products and our products may not be competitive, and our revenue and operating results may suffer.
If our customers do not incorporate our technologies into their products, or if our customers’ products are not commercially successful, our business would suffer.
Our products may not be successful in new markets.
We purchase inventory in advance based on expected demand for our products, and if demand is not as expected, we may have insufficient or excess inventory, which could adversely impact our financial condition.
Our future revenue depends in meaningful part on sustaining or growing our licensing revenue and the failure to achieve such revenue would lead to a material decline in our results of operations.
Our revenue consists mainly of patentlicensing cycle is lengthy and technology license fees paid for access tocostly, and our patents, developed technologymarketing and development and support services provided to our customers. Our ability to secure and renew the licenses from which our revenues are derived depends on our customers adopting our technology and using it in the products they sell. Once secured, license revenuelicensing efforts may be negatively affected by factors withinunsuccessful.
Some of our license agreements may convert from royalty generating to fully paid-up licenses at the expiration of their terms, or upon certain milestones, and outside our control, including reductions in our customers’ sales prices, sales volumes,we may not receive royalties after that time.
Future revenue is difficult to predict for several reasons, and our failure to timely complete engineering deliverables,predict revenue or revenue trends accurately may result in our stock price declining.
We may fail to meet our publicly announced guidance or other expectations about our business, which would likely cause our stock price to decline.
A substantial portion of our revenue is derived from sources outside of the United States and this revenue and our business generally are subject to risks related to international operations that are often beyond our control.
Weak global economic conditions may adversely affect demand for the termsproducts and services of such licenses. our customers and could otherwise harm our business.
Our operations are subject to the effects of a rising rate of inflation.
We rely on third parties for a variety of services, including manufacturing, and these third parties’ failure to perform these services adequately or change the allocation of their services/capacity due to industry or other pressures could materially and adversely affect our business.
Our business and operations could suffer in the event of physical and cybersecurity breaches and incidents.
We have in the past made and may in the future make acquisitions or enter into mergers, strategic investments, sales of assets, divestitures or other arrangements that may not produce expected operational benefits or operating and financial results.
If we are unable to attract and retain qualified personnel globally, our business and operations could suffer.
Our operations are subject to risks of natural disasters, acts of war, terrorism, widespread illness or security breaches or incidents at our domestic and international locations, any one of which could result in a business stoppage and negatively affect our operating results.

In addition,the future, we may fail to maintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material misstatements of our licensing cycle for new licenseesconsolidated financial statements or cause us to fail to meet our periodic reporting obligations.
Unanticipated changes in our tax rates or in the tax laws, treaties and regulations could expose us to additional income tax liabilities, which could affect our operating results and financial condition.
We are subject to various government restrictions and regulations, including on the sale of products and services that use encryption and other technology and those related to privacy and other consumer protection matters.
Litigation and government proceedings could affect our business in materially negative ways.
If we are unable to protect our inventions successfully through the issuance and enforcement of patents, our operating results could be adversely affected.
Third parties may claim that our products or services infringe on their intellectual property (“IP”) rights, exposing us to litigation that, regardless of merit, may be costly to defend.
Warranty, service level agreement and product liability claims brought against us could cause us to incur significant costs and adversely affect our operating results, as well as renewals for existing licensees is lengthy, costlyour reputation and unpredictable without any degreerelationships with customers.
Compliance with changing regulation of certainty. We cannot provide any assurance that we will be successfulcorporate governance and public disclosure may result in signing new license agreements or renewing existing license agreements on equal or favorable terms or at all. If we do not achieve our revenue goals, our results of operations could decline.additional expenses.

Risks Associated with Our Business, Industry and Market Conditions
We have traditionally operated in, and may enter other, industries that are highly cyclical and competitive.
Our target customers are companies that develop and market high volume business and consumer products in semiconductors, computing, data centers, networks, tablets, handheld devices, mobile applications, gaming and graphics, high-definition televisions, general lighting, cryptography and data security. The electronics industry is intensely competitive and has been impacted by rapid technological change, short product life cycles, cyclical market patterns, price erosion and increasing foreign and domestic competition. We are subject to many risks beyond our control that influence whether or not we are successful in winning target customers or retaining existing customers, including, primarily, competition in a particular industry, market acceptance of such customers'customers’ products and the financial resources of such customers. In particular, DRAM manufacturers, which such customers make up a significant part of our revenue, are prone to significant business cycles and have suffered material losses and other adverse effects to their businesses, leading to industry consolidation from time-to-time that may result in loss of revenuesrevenue under our existing license agreements or loss of target customers. As a result of ongoing competition in the industries in which we operate and volatility in various economies around the world, we may achieve reduced market share, a reduced number of licenses or may experience tightening of customers'customers’ operating budgets, difficulty or inability of our customers to pay our licensing fees, reduction in downstream demand, lengthening of the approval process for new products and licenses and consolidation among our customers. All of these factors may adversely affect the demand for our technologyproducts and technologies and may cause us to experience substantial fluctuations in our operating results.results and financial condition.
We face competition from semiconductor and digital electronics products and systems companies, and other semiconductor intellectual propertyIP companies that provide security cores and non-edge lit LED lighting optionsinterface IP that are available to the market. We believe some of the principal competition for our technologies may come from our prospective customers, some of which are internally evaluating and developing products based on technologies that they contend or may contend will not require a license from us. Some of our competitors use a system-level design approach similar to ours, including activities such as board and package design, power and signal integrity analysis, and thermal management. Many of these companies are larger and may have better access to financial, technical and other resources than we possess.possess and may be able to develop and advance competitive products more effectively.
To the extent that alternativesalternative technologies might provide comparable system performance at lower or similar cost to our technologies, or are perceived to require the payment of no or lower fees and/or royalties, or to the extent other factors influence the industry, our customers

and prospective customers may adopt and promote such alternative technologies. Even to the extent we determine that such alternative technologies infringe our patents, there can be no assurance that we would be able to negotiate agreements that would result in royalties being paid to us without litigation, which could be costly and the results of which would be uncertain.
In addition, our expansionefforts to expand into new markets subjectssubject us to additional risks. We may have limited or no experience in new products and markets, including our CryptoManager platform and new offerings that have resulted from our acquisition of SCS in the mobile payment and smart ticketing solution spaces, and our acquisitions of the assets of the Snowbush IP group and the Memory Interconnect Business, and our customers may not adopt our new offerings. These and other new offerings may present new and difficult challenges, which could negatively affect our operating results.

We may have to invest more resources in research and development than anticipated, which could increaseMuch of our operating expenses and negatively impact our operating results.

If new competitors, technological advances by existing competitors, and/or development of new technologies or other competitive factors require us to invest significantly greater resources than anticipated in our research and development efforts, our operating expenses could increase. If we are required to invest significantly greater resources than anticipated in research and development efforts without an increase in revenue, our operating results would decline. We expect these expenses to increase in the foreseeable future as our technology development efforts continue.
Our revenue is concentrated in a few customers, and if we lose any of these customers through contract terminations or acquisitions, our revenue may decrease substantially.
We have a high degree of revenue concentration. Our top five customers for each reporting period represented approximately 56%59% and 65%57% of our revenue for the nine months ended September 30, 20172023 and 2016,2022, respectively. For both of the nine months ended September 30, 2017 and 2016, revenue from Micron, Samsung and SK hynix each accounted for 10% or more of our total revenue. Additionally, our top five customers represented approximately 63%58% and 65%56% of our revenuesrevenue for the years ended December 31, 20162022 and 2015,2021, respectively. For both of the years ended December 31, 2016 and 2015, revenues from Micron, Samsung and SK hynix each accounted for 10% or more of our total revenue in each year. We extended our license agreement with Samsung in December 2013, and we expect Samsung to continue to account for a significant portion of our licensing revenue. We also entered into settlement agreements with each of SK hynix and Micron (which included Elpida, which Micron had acquired in July 2013) in June 2013 and December 2013, respectively. In June 2015, we also extended our license agreement with SK hynix. As a result of the renewal and such settlements, we expect each of Samsung, SK hynix and Micron to account for a significant portion of our licensing revenue in the future. We expect to continue to experience significant revenue concentration for the foreseeable future. Our customers’ demand for our products
44


may fluctuate due to factors beyond our control. We could experience fluctuations in our customer base or the mix of revenue by customer as markets and strategies evolve. A disruption in our relationship with any of our customers could adversely affect our business. In addition, any consolidation of our customers could reduce the number of customers to whom our products may be sold or the demand for our products. Our inability to meet our customers’ requirements or to qualify our products with them could adversely impact our revenue. The loss of, or restrictions on our ability to sell to, one or more of our major customers, or any significant reduction in orders from, or a shift in product mix by, customers could have a material adverse effect on our operating results and financial condition.
In addition, our license agreements are complex and some contain terms that require us to provide certain customers with the lowest royalty rate that we provide to other customers for similar technologies, volumes and schedules. These clauses may limit our ability to effectively price differently among our customers, to respond quickly to market forces, or otherwise to compete on the basis of price. These clauses may also require us to reduce royalties payable by existing customers when we enter into or amend agreements with other customers. Any adjustment that reduces royalties from current customers or licensees may have a material adverse effect on our operating results and financial condition.
We continue to negotiate with customers and prospective customers to enter into license agreements. Any future agreement may trigger our obligation to offer comparable terms or modifications to agreements with our existing customers, which may be less favorable to us than the existing license terms. We expect licensing fees will continue to vary based on our success in renewing existing license agreements and adding new customers, as well as the level of variation in our customers'customers’ reported shipment volumes, sales price and mix, offset in part by the proportion of customer payments that are fixed. In particular, under our license agreement with Samsung, the license fees payable by Samsung are subject to certain adjustments and conditions, and we therefore cannot provide assurances that the revenues generated by this license will not decline in the future. In addition, some of our material license agreements may contain rights by the customer to terminate for convenience, or upon certain other events, such as change of control, material breach, insolvency or bankruptcy proceedings. If we are unsuccessful in entering into license agreements with new customers or renewing license agreements with existing customers, on favorable terms or at all, or if they are terminated, our results of operations may decline significantly.
Our business and operations could suffer in the event of security breaches.
Attempts by others to gain unauthorized access to our information technology systems are becoming more sophisticated. These attempts, which might be related to industrial or other espionage, include covertly introducing malware to our computers and networks and impersonating authorized users, among others. We seek to detect and investigate all security incidents and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. While we have not identified any material incidents of unauthorized access to date, the theft, unauthorized use or publication of our intellectual

property and/or confidential business information could harm our competitive position and reputation, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. To the extent that any future security breach results in inappropriate disclosure of our customers' confidential information, we may incur liability.
Failures in our products and services or in the products of our customers, including those resulting from security vulnerabilities, defects, bugs or errors, could harm our business.
Our products and services are highly technical and complex, and among our various businesses our products and services are crucial to providing security, payment and other critical functions for our customers’ operations. Our products and services have from time to time contained and may in the future contain undetected errors, bugs defects or other security vulnerabilities. Some errors in our products and services may only be discovered after a product or service has been deployed and used by customers, and may in some cases only be detected under certain circumstances or after extended use. In addition, because the techniques used by hackers to access or sabotage our products and services and other technologies change and evolve frequently and generally are not recognized until launched against a target, we may be unable to anticipate, detect or prevent these techniques and may not address them in our data security technologies. Any errors, bugs, defects or security vulnerabilities discovered in our solutions after commercial release could adversely affect our revenue, our customer relationships and the market's perception of our products and services. We may not be able to correct any errors, bugs, defects, security flaws or vulnerabilities promptly, or at all. Any breaches, defects, errors or vulnerabilities in our products and services could result in:

expenditure of significant financial and research and development resources in efforts to analyze, correct, eliminate or work around breaches, errors, bugs or defects or to address and eliminate vulnerabilities;
financial liability to customers for breach of certain contract provisions, including indemnification obligations;
loss of existing or potential customers;
delayed or lost revenue;
delay or failure to attain market acceptance;
negative publicity, which would harm our reputation; and
litigation, regulatory inquiries or investigations that would be costly and harm our reputation.
Some of our revenue is subject to the pricing policies of our customers over which we have no control.
We have no control over our customers'customers’ pricing of their products and there can be no assurance that licensed products will be competitively priced or will sell in significant volumes. Any premium charged by our customers in the price of memory and controller chips or other products over alternatives must be reasonable. If the benefits of our technology do not match the price premium charged by our customers, the resulting decline in sales of products incorporating our technology could harm our operating results.
Our customers often require our products to undergo a lengthy and expensive qualification process which does not assure product sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, our business and operating results would suffer.
Prior to purchasing our products, our customers often require that our products undergo extensive qualification processes, which involve testing of our products in the customers’ systems, as well as testing for reliability. This qualification process may continue for several months. However, qualification of a product by a customer does not assure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision in third-party manufacturing processes may require a new qualification process with our customers, which may result in delays and in our holding excess or obsolete inventory. After our products are qualified, it can take several months or more before the customer commences volume production of components or systems that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, to qualify our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, sales of those products to the customer may be precluded or delayed, which may impede our growth and cause our business to suffer.
Products that fail to meet their specifications or are defective could impose significant costs on us or loss of business.
Products that do not meet their specifications or that contain, or are perceived by our customers to contain, defects could impose significant costs on us or otherwise materially adversely affect our operating results and financial condition. From time to time, we experience problems with nonconforming, defective, or incompatible products after we have shipped such products. In recent periods, we have further expanded our product offerings, which could potentially increase the chance that one or more of our products could fail to meet specifications in a particular application. Our products and technologies may be deemed fully or partially responsible for functionality in our customers’ products and may result in sharing or shifting of product or financial liability from our customers to us for costs incurred by the end user as a result of our customers’ products failing to perform as specified. In addition, if our products and technologies perform critical functions in our customers’ products or are used in high-risk consumer end products, such as automotive products, our potential liability may increase. We could be adversely affected in several ways, including the following:
45


we may be required or agree to compensate customers for costs incurred or damages caused by defective or incompatible products and to replace products;
we could incur a decrease in revenue or adjustment to pricing commensurate with the reimbursement of such costs or alleged damages;
we may encounter adverse publicity, which could cause a decrease in sales of our products or harm our reputation or relationships with existing or potential customers; and
our customers may reduce or cancel their orders with us or exclude us from further consideration as a supplier.
Any of the foregoing items could have a material adverse effect on our operating results and financial condition.
If we do not keep pace with technological innovations or customers’ increasing technological requirements, we may not be able to enhance our existing products and our products may not be competitive, and our revenue and operating results may suffer.
We operate in rapidly changing, highly competitive markets. Technological advances, the introduction of new products and new design techniques could adversely affect our business unless we are able to adapt to changing conditions. Technological advances could render our products and technologies less competitive or obsolete, and we may not be able to respond effectively to the technological requirements of evolving markets. Therefore, we may be required to commit significant resources to enhancing and developing new technology, which may include purchasing or licensing advanced design tools and test equipment, hiring additional highly qualified engineering and other technical personnel, and continuing and expanding research and development activities on existing and potential technologies.
Our existing product offerings may present new and difficult challenges, and we may be subject to claims if customers of our offerings experience delays, failures, non-performance or other quality issues. In particular, we may experience difficulties with product design, qualification, manufacturing, including supply chain disruptions or shortages that might lead to an inability to meet customer demand, marketing or certification that could delay or prevent our development, introduction or marketing and sales of products. Although we intend to design our products to be fully compliant with applicable industry standards, proprietary enhancements may not in the future result in full conformance with existing industry standards under all circumstances. Further, our products must be enhanced periodically to keep up with evolving system requirements. Our introduction of new products could reduce the demand and revenue of our older products or affect their pricing.
Our research and development efforts with respect to new technologies may not result in customer or market acceptance. Some or all of those technologies may not successfully make the transition from the research and development stage to cost-effective production as a result of technology problems, competitive cost issues, yield problems, and other factors. Even if we successfully complete a research and development effort with respect to a particular technology, our customers may decide not to introduce or may terminate products utilizing the technology for a variety of reasons, including difficulties with other suppliers of components for the products, superior technologies developed by our competitors and unfavorable comparisons of our products with these technologies, price considerations and lack of anticipated or actual market demand for the products.
Our business model continues to transform towards greater reliance on product revenue. We have recently experienced both growth and decline in sales of our memory interface chips quarter over quarter. We could experience a slowdown in our customers’ demand for our products in the near term, however, we anticipate our memory interface chips will contribute to continued long-term growth. If sales of our memory interface chips do not grow as anticipated, then our business could suffer as a result. Our business could be harmed if we are unable to develop and utilize new technologies that address the needs of our customers, or our competitors or customers develop and utilize new technologies more effectively or more quickly than we can. A transition by our customers to different business models could also result in reduced revenue. We cannot guarantee that we will be successful in keeping pace with all, or any, of the customer trends. Any investments made to enhance or develop new technologies that are not successful could have an adverse effect on our operating results and financial condition.
If our customers do not incorporate our technologies into their products, or if our customers’ products are not commercially successful, our business would suffer.
We sell our memory interface chips directly and indirectly to memory module manufacturers and OEMs worldwide for integration into server memory modules. We cannot be assured that our customer’s products will be commercially successful over time or at all as a result of factors beyond our control. If products incorporating our technologies are not commercially successful or experience rapid decline, our revenue and business will suffer. Further, we are continuing to expand into new segments and if our memory interface chips fail to achieve acceptance by customers in such segments, then our business could suffer as a result. Changes in our customers’ order patterns could result in us holding excess quantities of inventory which could result in us recording reserves for excess and obsolete inventory. Any such reserves would have an adverse effect on our operating results and financial condition.

We purchase inventory in advance based on expected demand for our products, and if demand is not as expected, we may have insufficient or excess inventory, which could adversely impact our financial condition
As a fabless semiconductor company, we purchase our inventory from third-party manufacturers in advance of selling our products. We place orders with our manufacturers based on existing and expected orders from our customers for particular products. While most of our contracts with our customers and distributors include lead time requirements and cancellation penalties that are designed to protect us from misalignment between customer orders and inventory levels, we must nonetheless make some predictions when we place orders with our manufacturers and we are not always able to make adjustments to align with our inventory needs. Our customers and distributors may cancel orders for many reasons, including but not limited to the impacts of the global economic downturn, business challenges, supply chain constraints, or other changes in their business requirements. In the event that our predictions are inaccurate due to unexpected increases in orders or our manufacturers are unable to provide the inventory that we require, we may have insufficient inventory to meet our customers’ demands. In addition, a perceived negative trend in market conditions could lead us to decrease the manufacturing volume of our products to avoid excess inventory. If we inaccurately assess market conditions for our products, we could have insufficient inventory to meet our customer demands resulting in loss of revenue. In the event that we order products that we are unable to sell due to a decrease in orders, unexpected order cancellations, import/export restrictions or product returns, we may have excess inventory which, if not sold, may need to be written down or would result in a decrease in our revenue in future periods. If any of these situations were to arise, it could have a material impact on our business, financial condition and results of operations.
Our products may not be successful in new markets.
Various target markets for our products, such as AI, may develop slower than anticipated or could utilize competing technologies. The markets for some of these products depend in part upon the continued development and deployment of wireless and other technologies, which may or may not address the needs of the users of these products. We cannot predict the size or growth rate of these markets or the market share we will achieve or maintain in these markets in the future.
Our ability to generate significant revenue from new markets will depend on various factors, including the development and growth of these markets; the ability of our technologies and products to address the needs of these markets; the price and performance requirements of our customers, and the preferences of end users; and our ability to provide our customers with products that provide advantages compared with alternative products.
Our ongoing success in these markets will require us to offer better performance alternatives to other products at competitive costs. The failure of any of these target markets to develop as we expect, or our failure to serve these markets to a significant extent, will impede the sales growth of products incorporating our technology, which could harm our operating results.
Our future revenue depends in meaningful part on sustaining or growing our licensing revenue and the failure to achieve such revenue would lead to a material decline in our results of operations.
While our business model continues to transform towards greater reliance on product revenue, a large portion of our revenue consists of fees paid for access to our patented technologies, existing technology and other development and support services we provide to our customers. Our ability to secure and renew the licenses from which our revenue is derived depends on our customers adopting our technology and using it in the products they sell. If customers do not upgrade or enhance their product offerings to include such technologies, our revenue and operating results may be adversely affected. Once secured, license revenue may be negatively affected by factors within and outside our control, including reductions in our customers’ sales prices, sales volumes, our failure to timely complete engineering deliverables, and the actual terms of such licenses themselves. In addition, our licensing cycle for new licensees, as well as for renewals for existing licensees is lengthy, costly and unpredictable. We cannot provide any assurance that we will be successful in signing new license agreements or renewing existing license agreements on equal or favorable terms or at all. If we do not achieve our revenue goals, our results of operations could decline.
Our licensing cycle is lengthy and costly, and our marketing and licensing efforts may be unsuccessful.
The process of persuading customers to adopt and license our chip interface, lighting, data security IP, and other technologies can be lengthy. Even if successful, there can be no assurance that our technologies will be used in a product that is ultimately brought to market, achieves commercial acceptance or results in significant royalties to us. We generally incur significant marketing and sales expenses prior to entering into our license agreements, generating a license fee and establishing a royalty stream from each customer. The length of time it takes to establish a new licensing relationship can take many months or even years. We may incur costs in any particular period before any associated revenue stream begins, if at all. If our marketing and sales efforts are very lengthy or unsuccessful, then we may face a material adverse effect on our business and results of operations as a result of failure to obtain, or an undue delay in obtaining, royalties.
47


Some of our license agreements may convert from royalty generating to fully paid-up licenses at the expiration of their terms, or upon certain milestones, and we may not receive royalties after that time.
From time to time, we enter into license agreements that automatically convert from royalty generating arrangements to fully paid-up licenses under which the customer is no longer required to make payments for the licensed technology or IP upon expiration or upon reaching certain milestones. We may not receive further royalties from customers for any licensed technology under those agreements if they convert to fully paid-up licenses because such customers will be entitled to continue using some, if not all, of the relevant IP or technology under the terms of the license agreements without further payment, even if relevant patents or technologies are still in effect. If we cannot find another source of royalties to replace the royalties from these license agreements converting to fully paid-up licenses, our results of operations following such conversion could be adversely affected.
Future revenue is difficult to predict for several reasons, and our failure to predict revenue or revenue trends accurately may result in our stock price declining.
As we commercially launch each of our products, the sales volume of and resulting revenue from such products in any given period will be difficult to predict. Our lengthy license negotiation cycles could make a considerable portion of our future revenue difficult to predict because we may not be successful in entering into or renewing licenses with our customers on our anticipated timelines.
In addition, while some of our license agreements provide for fixed, quarterly royalty payments, many of our license agreements provide for volume-based royalties and may also be subject to caps on royalties in a given period. The sales volume and prices of our customers'customers’ products in any given period can be difficult to predict. Furthermore, when we apply the Standard forUnder revenue recognition standard (“ASC 606”) adopted during the first quarter of 2018, we anticipate that our revenue will vary a great dealvaries greatly from quarter to quarter as discussed further below.quarter. As a result of the foregoing items, our actual results may differ substantially from analyst estimates or our forecasts in any given quarter.

Also, a portion of our revenue comes from development and support services provided to our customers. Depending upon the nature of the services, a portion of the related revenue may be recognized ratably over the support period, or may be recognized according to contract revenue accounting. Contract revenue accounting may result in deferral of the service fees tountil the completion of the contract, or may result in the recognition of service fees over the period in which services are performed on a percentage-of-completion basis.
We may not be successful in entering into new markets, and our new product offerings, such as our acquisitions of SCS, the assets of the Snowbush IP group and the Memory Interconnect Business, our CryptoManager platform and new offerings in the mobile credential and smart card solution spaces, may not be adopted by our customers or potential customers. In addition, once we commercially launch our products, the sales volume of and resulting revenue from such products in any given period will be difficult to predict.

We may fail to meet our publicly announced guidance or other expectations about our business, which would likely cause our stock price to decline.

We provide guidance regarding our expected financial and business performance including our anticipated future revenues,revenue, operating expenses and other financial and operation metrics. We are evaluating the form and content of any guidance that we may provide following implementation of the Standard, a new revenue recognition standard that will be effective for the first quarter of 2018, and expect our guidance metrics to change.
Correctly identifying the key factors affecting business conditions and predicting future events is an inherently uncertain process. Any guidance that we provide may not always be accurate, or may vary from actual results, due to our inability to correctly identify and quantify risks and uncertainties to our business and to quantify their impact on our financial performance. We offer no assurance that such guidance will ultimately be accurate, and investors should treat any such guidance with appropriate caution. If we fail to meet our guidance or if we find it necessary to revise such guidance, even if such failure or revision is seemingly insignificant, investors and analysts may lose confidence in us and the market value of our common stock could be materially adversely affected.
Changes in accounting principles and guidance could result in unfavorable accounting charges or effects.
We prepare our financial statements in accordance with accounting principles generally accepted in the United States and these principles are subject to interpretation by the SEC and various bodies. A change in these principles or application guidance, or in their interpretations, may have a material effect on our reported results, as well as our processes and related controls, and may retroactively affect previously reported results. For example, in May 2014, the FASB issued the Standard. The Standard, as amended, is effective for us on January 1, 2018. We have yet to make a final decision regarding the adoption method we will use, but we believe we will adopt the Standard on a full retrospective basis, with a cumulative-effect adjustment to the opening balance of retained earnings on January 1, 2016 determined on the basis of the impact of the Standard on the accounting for contracts that are not completed as of that date. Although we have yet to finalize our evaluation and quantification of the effects that the Standard will have on our consolidated financial statements, and to finalize the design and implementation of related changes to our policies, procedures and controls, we expect the Standard to materially impact the timing of revenue recognition for our fixed-fee intellectual property (IP) licensing arrangements (including certain fixed-fee agreements that license our existing IP portfolio as well as IP added to our portfolio during the license term) as a majority of such revenue would be recognized at inception of the license term, as opposed to over time as is the case under current U.S. GAAP, and we will be required to compute and recognize interest income over time as control over the IP generally transfers significantly in advance of cash being received from customers. We are also evaluating the form and content of any guidance that we may provide following implementation of the Standard and expect our guidance metrics to change. We expect that any change to current revenue recognition practices may significantly increase volatility in our quarterly revenue trends.
We have in the past made and may in the future make acquisitions or enter into mergers, strategic investments, sales of assets or other arrangements that may not produce expected operating and financial results.
From time to time, we engage in acquisitions, strategic transactions and strategic investments, such as our 2016 acquisitions of SCS, the assets of the Snowbush IP group and the Memory Interconnect Business. Many of our acquisitions or strategic investments entail a high degree of risk, including those involving new areas of technology and such investments may not become liquid for several years after the date of the investment, if at all. Our acquisitions or strategic investments may not provide the advantages that we anticipated or generate the financial returns we expect, including if we are unable to close any pending acquisitions. For example, for any pending or completed acquisitions, we may discover unidentified issues not discovered in due diligence, and we may be subject to liabilities that are not covered by indemnification protection or become subject to litigation. Achieving the anticipated benefits of business acquisitions depends in part upon our ability to integrate the acquired businesses in an efficient and effective manner. The integration of companies that have previously operated

independently may result in significant challenges, including, among others: retaining key employees; successfully integrating new employees, business systems and technology; retaining customers of the acquired business; minimizing the diversion of management's and other employees’ attention from ongoing business matters; coordinating geographically separate organizations; consolidating research and development operations; and consolidating corporate and administrative infrastructures.
Our strategic investments in new areas of technology may involve significant risks and uncertainties, including distraction of management from current operations, greater than expected liabilities and expenses, inadequate return of capital, and unidentified issues not discovered in due diligence. These investments are inherently risky and may not be successful.
In addition, we may record impairment charges related to our acquisitions or strategic investments. Any losses or impairment charges that we incur related to acquisitions, strategic investments or sales of assets will have a negative impact on our financial results and the market value of our common stock, and we may continue to incur new or additional losses related to acquisitions or strategic investments.
We may have to incur debt or issue equity securities to pay for any future acquisition, which debt could involve restrictive covenants or which equity security issuance could be dilutive to our existing stockholders.
From time to time, we may also divest certain assets, where we may be required to provide certain representations, warranties and covenants to their buyers. While we would seek to ensure the accuracy of such representations and warranties and fulfillment of any ongoing obligations, we may not be completely successful and consequently may be subject to claims by a purchaser of such assets.
A substantial portion of our revenue is derived from sources outside of the United States and this revenue and our business generally are subject to risks related to international operations that are often beyond our control.
For the nine months ended September 30, 20172023 and 2016, revenues2022, revenue received from our international customers constituted approximately 58%approximately 61% and 65%42%, respectively, of ourour total revenue. Additionally, for the years ended December 31, 20162022 and 2015, revenues2021, revenue received from our international customers constituted approximately 64%39% and 60%36%, respectively, of our total revenue. We expect that future revenue derived from international sources will continue to represent a significant portion of our total revenue.
To the extent that customer sales are not denominated in U.S. dollars, any royalties which are based on a percentage of the customers'customers’ sales that we receive as a result of such sales could be subject to fluctuations in currency exchange rates. In addition, if the effective price of licensed products sold by our foreign customers were to increase as a result of fluctuations in the exchange rate of the relevant currencies, demand for licensed products could fall, which in turn would reduce our royalties. We do not use limited financial instruments to hedge foreign exchange rate risk, however such instruments may not be sufficient to cover such risk.
Trade-related government actions, whether implemented by the United States, China, European Union or other countries, that impose barriers or restrictions that would impact our ability to sell or ship products to certain customers may have a
48


negative impact on our financial condition and results of operations. We cannot predict the actions government entities may take in this context and may be unable to quickly offset or effectively react to government actions that restrict our ability to sell to certain customers or in certain jurisdictions. Government actions that affect our customers’ ability to sell products or access critical elements of their supply chains may result in a decreased demand for their products, which may consequently reduce their demand for our products.
In addition, the U.S. government has announced controls affecting the ability to send certain products and technology related to semiconductors, semiconductor manufacturing and supercomputing to China without an export license and added additional entities to restricted party lists. While the Company currently has not been materially adversely impacted by these new restrictions, we may be impacted in the future if such controls are expanded to cover our key products/markets.
We currently have international business, operations in the United Kingdombusiness development, and the Netherlands, international design operations in Canada, China, India, Finland, France, Japan, the Netherlands, South Korea, Taiwan, and France, and business development operations in Australia, China, Japan, Korea, Singapore and Taiwan.Bulgaria. Our international operations and revenue are subject to a variety of risks which are beyond our control, including:
hiring, maintaining and managing a workforce and facilities remotely and under various legal systems, including compliance with local labor and employment laws;
non-compliance with our code of conduct or other corporate policies;
compliance with and international laws involving international operations, including the Foreign Corrupt Practices Act of 1977, as amended, sanctions and anti-corruption laws, export and import laws, and similar rules and regulations;
natural disasters, acts of war, terrorism, widespread global pandemics or illness, such as COVID-19 and its variants, or security breaches;breaches or incidents;
export controls, tariffs, import and licensing restrictions, climate-change regulations and other trade barriers;
profits, if any, earned abroad being subject to local tax laws and not being repatriated to the United States or, if repatriation is possible, limited in amount;
adverse tax treatment of revenue from international sources and changes to tax codes,laws and regulations, including being subject to foreign tax laws and being liable for paying withholding, income or other taxes in foreign jurisdictions;
longer payment cycles and greater difficulty in collecting accounts receivable;
unanticipated changes in foreign government laws and regulations;regulations including imposition of bans on sales of goods or services to one or more of our significant foreign customers;
increased financial accounting and reporting burdens and complexities;
lack of protection of our intellectual propertyIP and other contract rights by jurisdictions in which we may do business to the same extent as the laws of the United States;
potential vulnerability to computer system, internet or other systemic attacks, such as denial of service, viruses or other malware which may be caused by criminals, terrorists or other groups or sophisticated organizations;
social, political and economic instability;
geopolitical issues,instability, including changes in diplomatic and trade relationships;relationships, in particular with China and Taiwan; and
cultural differences in the conduct of business both with customers and in conducting business in our international facilities and international sales offices.

We and our customers are subject to many of the risks described above with respect to companies which are located in different countries. There can be no assurance that one or more of the risks associated with our international operations will not result in a material adverse effect on our business, financial condition or results of operations.
Weak global economic conditions may adversely affect demand for the products and services of our customers.customers and could otherwise harm our business.
Our operations and performance depend significantly on worldwide economic conditions. Uncertainty aboutCurrent and future uncertainty in the worldwide economy, due to inflation, geopolitics, major central bank policies including interest rate increases, public health crises, or other global or regionalfactors could adversely affect our business. Adverse economic and political conditions poses a risk as consumers and businesses may postpone spending in response to tighter credit, negative financial news and declines in income or asset values, which could have a material negative effect on thealso affect demand for theour products ofand our customers in the foreseeable future.customers’ products. If our customers experience reduced demand for their productsor excess inventory as a result of global or regional economic conditions or otherwise, this could result in reduced royalty revenue and/or product sales and our business and results of operations could be harmed.
If our counterparties are unable Inflationary pressures and shortages have increased, and may continue to fulfill their financialincrease, costs for materials, supplies, and other obligations to us, our business and results of operations may be affected adversely.
Any downturn in economic conditions or other business factors could threaten the financial health of our counterparties, including companies with which we have entered into licensing and/or settlement agreements, and their ability to fulfill their financial and other obligations to us. Such financial pressures on our counterparties may eventually lead to bankruptcy proceedings or other attempts to avoid financial obligations that are due to us. Because bankruptcy courts have the power to modify or cancel contracts of the petitioner which remain subject to future performance and alter or discharge payment obligations related to pre-petition debts, we may receive less than all of the payments that we would otherwise be entitled to receive from any such counterparty as a result of bankruptcy proceedings.
If we are unable to attract and retain qualified personnel, our business and operations could suffer.
Our success is dependent upon our ability to identify, attract, compensate, motivate and retain qualified personnel, especially engineers, senior management and other key personnel. The loss of the services of any key employees could be disruptive to our development efforts or business relationshipslabor and could cause our expenses to increase at a rate faster than our product pricing to recover such increases which may result in a material adverse effect on our business, financial condition or results of operations.
49


Additionally, deterioration of conditions in worldwide credit markets could limit our ability to obtain external financing, if needed, to fund our operations and operationscapital expenditures. In addition, we may experience losses on our holdings of cash and investments due to suffer.
We are subject to various government restrictions and regulations, including on the salefailures of products and services that use encryption technology and those related to privacyfinancial institutions and other consumer protection matters.
Various countries have adopted controls, license requirements and restrictionsparties. Difficult economic conditions may also result in a higher rate of losses on the export, import and use of products or services that contain encryption technology. In addition, governmental agencies have proposed additional requirements for encryption technology, such as requiring the escrow and governmental recovery of private encryption keys. Restrictions on the sale or distribution of products or services containing encryption technology may impact the ability of RSDour accounts receivable due to license its data security technologies to the manufacturers and providers of such products and services in certain markets or may require RSD or its customers to make changes to the licensed data security technology that is embedded in such products to comply with such restrictions. Government restrictions, or changes to the products or services of RSD's customers to comply with such restrictions, could delay or prevent the acceptance and use of such customers' products and services. In addition, the United States and other countries have imposed export controls that prohibit the export of encryption technology to certain countries, entities and individuals. Our failure to comply with export and use regulations concerning encryption technology of RSD could subject us to sanctions and penalties, including fines, and suspension or revocation of export or import privileges.
We are subject tocredit defaults. As a variety of laws and regulationsresult, downturns in the United States, the European Union and other countries that involve, for example, user privacy, data protection and security, content and consumer protection. A numberworldwide economy could have a material adverse effect on our business, results of proposals are pending before federal, state, and foreign legislative and regulatory bodies that could significantlyoperations, or financial condition.
Any failure in our delivery of high-quality technical support services may adversely affect our business. Existing and proposed laws and regulations can be costly to comply with and can delay or impede the development of new products, result in negative publicity, increase our operating costs and subject us to claims or other remedies.
In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC established new disclosure and reporting requirements for those companies that use "conflict" minerals mined from the Democratic Republic of Congo and adjoining countries in their products, whether or not these products are manufactured by third parties. These requirements could affect the sourcing and availability of minerals that are used in the manufacture of our products. We have to date incurred costs and expect to incur significant additional costs associated with complying with the disclosure requirements, including for example, due diligence in regard to the sources of any conflict minerals used in our products, in addition to the cost of remediation and other changes to products, processes, or sources of supply as a consequence of such verification activities. Additionally, we may face reputational challengesrelationships with our customers and other stakeholders if we areour financial results.
Our customers depend on our support organization to resolve technical issues and provide ongoing maintenance relating to our products and services. We may be unable to sufficiently verify the origins of all minerals usedrespond quickly enough to accommodate short-term increases in customer demand for support services. Increased customer demand for these services, without corresponding revenue, could increase costs and adversely affect our products through the due diligence proceduresoperating results. In addition, our sales process is highly dependent on our offerings and business reputation and on positive recommendations from our existing customers. Any failure to maintain high-quality technical support, or a market perception that we implement. We may also face challenges with government regulatorsdo not maintain high-quality support, could adversely affect our reputation, our ability to sell our solutions to existing and prospective customers, and our customersbusiness, operating results and suppliers if we are unable to sufficiently verify that the metals used in our products are conflict free.

financial position.
Our operations are subject to risksthe effects of a rising rate of inflation.
The United States has recently experienced historically high levels of inflation. If the inflation rate increases or remains high, such as a result of increases in the costs of labor and supplies, it will affect our expenses, such as employee compensation and research and development charges. Research and development expenses account for a significant portion of our operating expenses. Additionally, the United States is experiencing an acute workforce shortage, which in turn, has created a competitive wage environment that may increase the Company’s operating costs. To the extent inflation results in rising interest rates and has other adverse effects on the market, it may adversely affect our consolidated financial condition and results of operations.
Risks Associated with Our Supply and Third Party Manufacturing
We rely on third parties for a variety of services, including manufacturing, and these third parties’ failure to perform these services adequately or change the allocation of their services/capacity due to industry or other pressures could materially and adversely affect our business.
We rely on third parties for a variety of services, including our manufacturing supply chain partners and third parties within our sales and distribution channels. Some of these third parties are, and may be, our sole manufacturer or sole source of certain production materials and may be located in regions subject to geopolitical uncertainty (e.g., tensions between China and Taiwan). If we fail to manage our relationships with these manufacturers and suppliers effectively, or if they experience delays, disruptions, geopolitical changes, capacity constraints/allocation pressures or quality control problems in their operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. In addition, any adverse change in any of our manufacturers and suppliers’ financial or business condition could disrupt our ability to supply quality products to our customers. If we are required to change our manufacturers, we may lose revenue, incur increased costs and damage our end-customer relationships. In addition, porting to and qualifying a new manufacturer and commencing production can be an expensive and lengthy process. If our third-party manufacturers or suppliers are unable to provide us with adequate supplies of high-quality products for any other reason, we could experience a delay in our order fulfillment, and our business, operating results and financial condition would be adversely affected. In the event these and other third parties we rely on fail to provide their services adequately, including as a result of errors in their systems, industry pressures or events beyond their control, or refuse to provide these services on terms acceptable to us, and we are not able to find suitable alternatives, our business may be materially and adversely affected. In addition, our orders may represent a relatively small percentage of the overall orders received by our manufacturers from their customers. As a result, fulfilling our orders may not be considered a priority in the event our manufacturers are constrained in their ability to fulfill all of their customer obligations in a timely manner. If our manufacturers are unable to provide us with adequate supplies of high-quality products, or if we or our manufacturers are unable to obtain adequate quantities of components, it could cause a delay in our order fulfillment, in which case our business, operating results and financial condition could be adversely affected.
Semiconductor supply chain disruptions have been well publicized in the recent past. We believe that we could experience various supply constraints related to our memory interface chip business in the future. In particular, to the extent we do not have sufficient wafer and packaging substrate firm commitments from our third-party suppliers, or they are otherwise unable to provide such services and materials, we may not obtain the materials needed on our desired timelines or at reasonable prices. Large swings in demand could exceed our contracted supply and/or our suppliers’ capacity to meet those demand changes resulting in a shortage of parts, materials, or capacity needed to manufacture our products. While we continually work with our suppliers to mitigate the impact of the supply constraints to our customer deliveries, in the event of a shortage or supply interruption from suppliers of our components, we may not be able to develop alternate sources quickly, cost-effectively, or at
50


all. An extended period of global supply chain and economic disruption could have a material negative impact on our business, results of operations, access to sources of liquidity and financial condition, though the full extent and duration is uncertain.
Additionally, various sources of supply-chain risk, including strikes or shutdowns at delivery ports or loss of or damage to our products while they are in transit or storage, IP theft, losses due to tampering, third-party vendor issues with quality or sourcing control, failure by our suppliers to comply with applicable laws and regulations, potential tariffs or other trade restrictions, geopolitical uncertainty and related military actions, or other similar problems could limit or delay the supply of our products. Any interruption or delay in manufacturing or component supply, any increases in manufacturing or component costs, or the inability to obtain these services or components from alternate sources at acceptable prices and within a reasonable amount of time would harm our ability to provide our products to customers on a timely basis. This could harm our relationships with our customers, prevent us from acquiring new customers, and materially and adversely affect our business.
If the manufacturing and/or packaging process for our products is disrupted by operational issues, natural disasters, actsor other events, our business, results of war, terrorism, widespread illnessoperations, or security breachfinancial condition could be materially adversely affected.
We rely on subcontractors to manufacture and package our products using highly complex processes that require technologically advanced equipment and continuous modification. Our subcontractors maintain operations and continuously implement new product and process technology at facilities which are dispersed in multiple locations in Asia. As a result of the necessary interdependence within our domesticnetwork of manufacturing and international locations, anypackaging facilities, an operational disruption at one of whichour or a subcontractor’s facilities may have a disproportionate impact on our ability to produce many of our products.
From time to time, there have been disruptions in our subcontractors’ operations as a result of power outages, improperly functioning equipment, disruptions in supply of raw materials or components, or equipment failures. Our subcontractors have manufacturing and other operations in locations subject to natural disasters and possible climate changes, such as severe and variable weather and geological events resulting in increased costs, or disruptions to our manufacturing operations or those of our suppliers or customers. In addition, climate change may pose physical risks to our manufacturing facilities or our suppliers’ facilities, including increased extreme weather events that could result in supply delays or disruptions. Other events, including political or public health crises, such as an outbreak of contagious diseases like COVID-19 may also affect our subcontractors’ production capabilities.
If production is disrupted for any reason, manufacturing yields may be adversely affected, or we may be unable to meet our customers’ requirements and they may purchase products from other suppliers. This could result in a business stoppage and negatively affect our operating results.
Our business operations depend on our abilitysignificant increase in manufacturing costs, loss of revenue, or damage to maintain and protect our facilities, computer systems and personnel,customer relationships, any of which are primarily located in the San Francisco Bay Area in the United States, the United Kingdom, the Netherlands, India and Australia. The San Francisco Bay Area is in close proximity to known earthquake fault zones. Our facilities and transportation for our employees are susceptible to damage from earthquakes and other natural disasters such as fires, floods and similar events. Should a catastrophe disable our facilities, we do not have readily available alternative facilities from which we could conduct our business, so any resultant work stoppage could have a negativematerial adverse effect on our operating results. We also rely on our network infrastructure and technology systems for operational support and business activities which are subject to physical and cyber damage, and also susceptible to other related vulnerabilities common to networks and computer systems. Acts of terrorism, widespread illness, war and any event that causes failures or interruption in our network infrastructure and technology systems could have a negative effect at our international and domestic facilities and could harm our business, financial condition, and operating results.
We do not have extensive experience in manufacturing and marketing products and, as a result, may be unable to sustain and grow a profitable commercial market for new and existing products.
We do not have extensive experience in creating, manufacturing and marketing products, including our CryptoManager platform, our RLD product offerings and new offerings that have resulted from our acquisition of SCS in the mobile credential and smart card solution spaces, and our acquisitions of the assets of the Snowbush IP group and the Memory Interconnect Business. These and other new offerings may present new and difficult challenges, and we may be subject to claims if customers of these offerings experience delays, failures, non-performance or other quality issues. In particular, we may experience difficulties with product design, qualification, manufacturing, marketing or certification that could delay or prevent our development, introduction or marketing of new products. Although we intend to design our products to be fully compliant with applicable industry standards, proprietary enhancements may not in the future result in full conformance with existing industry standards under all circumstances.

If we fail to introduce products that meet the demand of our customers or penetrate new markets in which we expend significant resources, our revenues will decrease over time and our financial condition could suffer. Additionally, if we concentrate resources on a new market that does not prove profitable or sustainable, it could damage our reputation and limit our growth, and our financial condition could decline.

business.
We rely on a number of third-party providers for data center hosting facilities, equipment, maintenance and other services, and the loss of, or problems with, one or more of these providers may impede our growth or cause us to lose customers.

We rely on third-party providers to supply data center hosting facilities, equipment, maintenance and other services in order to enable us to provide some of our services, including in our offerings of our advanced mobile payment platform and smart ticketing platform, and have entered into various agreements for such services. The continuous availability of our serviceservices depends on the operations of those facilities, on a variety of network service providers and on third-party vendors. In addition, we depend on our third-party facility providers’ ability to protect these facilities against damage or interruption from natural disasters, power or telecommunications failures, criminal acts, cyber-attacks and similar events. If there are any lapses of service or damage to a facility, we could experience lengthy interruptions in our service, as well as delays and additional expenses in arranging new facilities and services. Even with current and planned disaster recovery arrangements, our business could be harmed. Any interruptions or delays in our service, whether as a result of third-party error, our own error, natural disasters, criminal acts, security breaches or other causes, whether accidental or willful, could harm our relationships with customers, harm our reputation and cause our revenue to decrease and/or our expenses to increase. Also, in the event of damage or interruption, our insurance policies may not adequately compensate us for any losses that we may incur. These factors in turn could further reduce our revenue, subject us to liability and cause us to issue credits or cause us to lose customers, any of which could materially adversely affect our business.

We rely on third parties for a variety of services, including manufacturing, and these third parties’ failure to perform these services adequately could materially and adversely affect our business.

We rely on third parties for a variety of services, including our manufacturing supply chain partners and third parties within our sales and distribution channels. Certain of these third parties are, and may be, our sole manufacturer or sole source of production materials. If we fail to manage our relationship with these manufacturers and suppliers effectively, or if they experience delays, disruptions, capacity constraints or quality control problems in their operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. In addition, any adverse

change in any of our manufacturers and suppliers’ financial or business condition could disrupt our ability to supply quality products to our customers. If we are required to change our manufacturers, we may lose revenue, incur increased costs and damage our end-customer relationships. In addition, qualifying a new manufacturer and commencing production can be an expensive and lengthy process. If our third party manufacturers or suppliers are unable to provide us with adequate supplies of high-quality products for any other reason, we could experience a delay in our order fulfillment, and our business, operating results and financial condition would be adversely affected. In the event these and other third parties we rely on fail to provide their services adequately, including as a result of errors in their systems or events beyond their control, or refuse to provide these services on terms acceptable to us or at all, and we are not able to find suitable alternatives, our business may be materially and adversely affected. In addition, our orders may represent a relatively small percentage of the overall orders received by our manufacturers from their customers. As a result, fulfilling our orders may not be considered a priority in the event our manufacturers are constrained in their ability to fulfill all of their customer obligations in a timely manner. If our manufacturers are unable to provide us with adequate supplies of high-quality products, or if we or our manufacturers are unable to obtain adequate quantities of components, it could cause a delay in our order fulfillment, in which case our business, operating results and financial condition could be adversely affected.

Warranty and product liability claims brought against us could cause us to incur significant costs and adversely affect our operating results as well as our reputation and relationships with customers.

We may from time to time be subject to warranty and product liability claims with regard to product performance and our services. We could incur material losses as a result of warranty, support, repair or replacement costs in response to customer complaints or in connection with the resolution of contemplated or actual legal proceedings relating to such claims. In addition to potential losses arising from claims and related legal proceedings, warranty and product liability claims could affect our reputation and our relationship with customers. We generally attempt to limit the maximum amount of indemnification or liability that we could be exposed to under our contracts, however, this is not always possible.

Any failure in our delivery of high-quality technical support services may adversely affect our relationships with our customers and our financial results.

Our customers depend on our support organization to resolve technical issues and provide ongoing maintenance relating to our products and services. We may be unable to respond quickly enough to accommodate short-term increases in customer demand for support services. Increased customer demand for these services, without corresponding revenues, could increase costs and adversely affect our operating results. In addition, our sales process is highly dependent on our offerings and business reputation and on positive recommendations from our existing customers. Any failure to maintain high-quality technical support, or a market perception that we do not maintain high-quality support, could adversely affect our reputation, our ability to sell our solutions to existing and prospective customers, and our business, operating results and financial position.

Certain software and/or IP blocks that we use in certainor with some of our products is licensed from third parties and, for that reason, may not be available to us in the future, which has the potential to delay product development and production or cause us to incur additional expense, which could materially adversely affect our business, financial condition, operating results and cash flow.

Some of our products and services contain or function with software and/or IP blocks licensed from third parties. Some of these licenses may not be available to us in the future on terms that are acceptable to us or allow our products to remain competitive. The loss of these licenses or the inability to maintain any of them on commercially acceptable terms could delay development of future offerings or the enhancement of existing products and services. We may also choose to pay a premium price for such a license in certain circumstances where continuity of the licensed product would outweigh the premium cost of
51


the license. The unavailability of these licenses or the necessity of agreeing to commercially unreasonable terms for such licenses could materially adversely affect our business, financial condition, operating results and cash flow.

Risks Associated with Our Business Operations
Certain softwareOur business and operations could suffer in the event of physical and cybersecurity breaches and incidents.
Attempts by others to gain unauthorized access to and disrupt our information technology systems are becoming more sophisticated. These attempts, which might be related to industrial or other espionage, may include covertly introducing malware to our computers and networks (or those of our customers) and impersonating authorized users, phishing attempts and other forms of social engineering, employee or contractor malfeasance, denial of service attacks and ransomware attacks, among others. We seek to detect and investigate all security incidents impacting our systems and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. We also utilize third-party service providers to host, transmit or otherwise process electronic data in connection with our business activities, including our supply chain processes, operations and communications. Our customers also often have access to and host our confidential IP and business information on their own internal and directed third party systems. We, our customers, and/or our third-party service providers have faced and may continue to face security threats and attacks from a variety of sources. Our data, corporate systems, third-party systems and security measures and those of our customers may be subject to breaches or intrusions due to the actions of outside parties, employee error, malfeasance, a combination of these, or otherwise, including social engineering and employee and contractor error or malfeasance, especially as certain of our employees engage in work from home arrangements, and, as a result, an unauthorized party may obtain access to our systems, networks, or data, including IP and confidential business information of ourselves and our customers. There have been and may continue to be significant supply chain attacks, and we cannot guarantee that our or our third-party service providers’ systems and networks have not been breached or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our systems and networks or the systems and networks of our customers or of third parties that support us and our services. We and our service providers may face difficulties or delays in identifying or responding to any actual or perceived security breach or incident. The theft or other unauthorized acquisition of, unauthorized use isor publication of, or access to our IP and/or confidential business information could harm our competitive position and reputation, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. In the event of any security breach or incident, including any breach or incident that results in inappropriate access to, or loss, corruption, unavailability, or unauthorized acquisition, disclosure or other processing of our or our customers’ confidential information or any personally-identifiable information we or our third-party service providers maintain, including that of our employees, we could suffer a loss of IP or loss of data, may be subject to claims, liability and proceedings, and may incur liability and otherwise suffer financial harm.
Any actual, alleged or perceived breach of security in our systems or networks, or any other actual, alleged or perceived data security incident we or our third-party service providers or customers suffer, could result in damage to our reputation, negative publicity, loss of customers and sales, harm to our market position, increased costs to remedy any problems and otherwise respond to any incident, regulatory investigations and enforcement actions, claims, litigation, proceedings and other liability. In addition, we may incur significant costs and operational consequences of investigating, remediating, eliminating and putting in place additional tools and devices designed to prevent actual or perceived security breaches and other security incidents, as well as the costs to comply with any notification or other legal obligations resulting from open source code sources, which,any security incidents. Any of these negative outcomes could result in substantial costs and diversion of resources, distract management and technical personnel, adversely impact our sales and reputation and seriously harm our business or operating results.
Although we maintain insurance coverage that may cover certain liabilities in connection with some security breaches and other security incidents, we cannot be certain our insurance coverage will be adequate for liabilities actually incurred, that insurance will continue to be available to us on commercially reasonable terms (if at all) or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, or denials of coverage, could have a material adverse effect on our business, including our financial condition, results of operations and reputation.
Failures in our products and services or in the products of our customers, including those resulting from security vulnerabilities, defects, bugs or errors, could harm our business.
Our products and services are highly technical and complex, and among our various businesses our products and services are crucial to providing security and other critical functions for our customers’ operations. Our products and services have from time to time contained and may in the future contain undetected errors, bugs, defects or other security vulnerabilities. Some errors in our products and services may only be discovered after a product or service has been deployed and used by customers, and may in some cases only be detected under certain circumstances or after extended use. In addition, because the techniques used by hackers to access or sabotage our products and services and other technologies change and evolve frequently and
52


generally are not recognized until launched against a target, we may leadbe unable to unintended consequencesanticipate, detect or prevent these techniques and therefore,may not address them in our data security technologies. Any errors, bugs, defects or security vulnerabilities discovered in our solutions after commercial release could materially adversely affect our business,revenue, our customer relationships and the market’s perception of our products and services. We may not be able to correct any errors, bugs, defects, security flaws or vulnerabilities promptly, or at all. Any breaches, defects, errors or vulnerabilities in our products and services could result in:
expenditure of significant financial condition, operatingand research and development resources in efforts to analyze, correct, eliminate or work around breaches, errors, bugs or defects or to address and eliminate vulnerabilities;
financial liability to customers for breach of certain contract provisions, including indemnification obligations;
loss of existing or potential customers;
product shipment restrictions or prohibitions to certain customers;
delayed or lost revenue;
delay or failure to attain market acceptance;
negative publicity, which would harm our reputation; and
litigation, regulatory inquiries or investigations that would be costly and harm our reputation.
Changes in accounting principles and guidance could result in unfavorable accounting charges or effects.
We prepare our financial statements in accordance with accounting principles generally accepted in the United States and these principles are subject to interpretation by the SEC, the Financial Accounting Standards Board (“FASB”) and various bodies formed to interpret and create appropriate accounting principles and guidance. A change in these principles or application guidance, or in their interpretations, may have a material effect on our reported results, as well as our processes and related controls, and may retroactively affect previously reported results. For instance, we adopted ASC 606, the Revenue Standard, effective for us on January 1, 2018, on a modified retrospective basis, with a cumulative-effect adjustment to the opening balance of accumulated deficit on January 1, 2018. The Revenue Standard materially impacted the timing of revenue recognition for our fixed-fee IP licensing arrangements (including certain fixed-fee agreements that license our existing IP portfolio, as well as IP added to our portfolio during the license term) as a majority of such revenue would be recognized at inception of the license term (as opposed to over time as was the case under prior U.S. GAAP). We have enhanced the form and content of some of our guidance metrics that we provide following implementation of the Revenue Standard. We expect that any change to current revenue recognition practices may significantly increase volatility in our quarterly revenue, financial results and cash flow.

trends, and may impact our stock price.
We use open source software in our services, including our advanced mobile payment platform and smart ticketing platform, and we intend to continue to use open source softwarehave in the future. past made and may in the future make acquisitions or enter into mergers, strategic investments, sales of assets, divestitures or other arrangements that may not produce expected operational benefits or operating and financial results.
From time to time, there have been claims challengingwe engage in acquisitions, strategic transactions, strategic investments, divestitures and potential discussions with respect thereto. For example, in 2019, we acquired Northwest Logic, Inc. (“Northwest Logic”) and the ownershipSecure Silicon IP and Protocols business from Verimatrix, formerly Inside Secure. Further, we acquired AnalogX Inc. (“AnalogX”) in July 2021, PLDA Group (“PLDA”) in August 2021, and Hardent, Inc. (“Hardent”) in May 2022. In July 2023, we entered into an asset purchase agreement with Cadence Design Systems to sell our PHY IP group, and the sale was completed in September 2023. Many of open source software against companiesour acquisitions or strategic investments entail a high degree of risk, including those involving new areas of technology and such investments may not become accretive for several years after the date of the investment, if at all. Our acquisitions or strategic investments may not provide the advantages that incorporate open source software into their productswe anticipated or alleging that these companies have violatedgenerate the terms of an open source license. As a result,financial returns we couldexpect, including if we are unable to close any pending acquisitions. For example, for any pending or completed acquisitions, we may discover unidentified issues not discovered in due diligence, and we may be subject to lawsuitsregulatory approvals or liabilities that are not covered by parties claiming ownershipindemnification protection or become subject to litigation.
Achieving the anticipated benefits of business acquisitions depends in part upon our ability to integrate the acquired businesses in an efficient and effective manner and achieve anticipated synergies, and we may not be successful in these efforts. The integration of companies that have previously operated independently is complex and time consuming and may result in significant challenges, including, among others: retaining key employees; successfully integrating new employees, facilities, products, processes, operations, business models and systems, technology, and sales and distribution channels; retaining customers and suppliers of the acquired business; minimizing the diversion of management’s and other employees’ attention from ongoing business matters; coordinating geographically separate organizations; consolidating research and development operations; consolidating corporate and administrative infrastructures; implementing controls, processes and policies appropriate for a public company at acquired companies that may have previously lacked such controls, processes and policies; and managing the increased scale, complexity and globalization of our business, operations and employee base.
53


Additional risks related to our acquisitions or strategic investments include, but are not limited to:
difficulty in combining the technology, products, or operations of the acquired business with our business;
difficulty in integrating and retaining the acquired workforce, including key employees;
diversion of capital and other resources, including management’s attention;
assumption of liabilities and incurring amortization expenses, impairment charges to goodwill or write-downs of acquired assets;
integrating financial forecasting and controls, procedures and reporting cycles;
coordinating and integrating operations in countries in which we have not previously operated;
acquiring business challenges and risks, including, but not limited to, disputes with management and integrating international operations and joint ventures;
difficulty in realizing a satisfactory return, if any return at all;
difficulty in obtaining or inability to obtain governmental and regulatory consents and approvals, other approvals or financing;
the potential impact of complying with governmental or other regulatory restrictions placed on an acquisition;
the potential impact on our stock price and financial results if we are unable to obtain regulatory approval for an acquisition, are required to pay reverse breakup fees or are otherwise unable to close an acquisition;
failure and costs associated with the failure to consummate a proposed acquisition or other strategic investment;
legal proceedings initiated as a result of an acquisition or investment;
the potential for our acquisitions to result in dilutive issuances of our equity securities;
the potential variability of the amount and form of any performance-based consideration;
uncertainties and time needed to realize the benefits of an acquisition or strategic investment, if at all;
negative changes in general economic conditions in the regions or the industries in which we or our acquired business operate;
the need to determine an alternative strategy if an acquisition does not meet our expectations;
potential failure of our due diligence processes to identify significant issues with the acquired assets or company; and
impairment of relationships with, or loss of our acquired business’ employees, vendors and customers, as a result of our acquisition or investment.
Our strategic investments in new areas of technology may involve significant risks and uncertainties, including distraction of management from current operations, greater than expected liabilities and expenses, inadequate return of capital, and unidentified issues not discovered in due diligence. These investments are inherently risky and may not be successful.
In addition, we may record impairment charges related to our acquisitions or strategic investments. Any losses or impairment charges that we incur related to acquisitions, strategic investments or sales of assets will have a negative impact on our financial results and the market value of our common stock, and we may continue to incur new or additional losses related to acquisitions or strategic investments.
We may have to incur debt or issue equity securities to pay for any future acquisitions, which debt could involve restrictive covenants or which equity security issuance could be dilutive to our existing stockholders. We may also use cash to pay for any future acquisitions which will reduce our cash balance.
From time to time, we may also divest certain assets. These divestitures or proposed divestitures may involve the loss of revenue and/or potential customers, and the market for the associated assets may dictate that we sell such assets for less than what we believepaid. In addition, in connection with any asset sales or divestitures, we may be required to provide certain representations, warranties, licenses and/or covenants to buyers. While we would seek to ensure the accuracy of such representations and warranties and fulfillment of any ongoing obligations, we may not be open source softwarecompletely successful and consequently may be subject to claims by a purchaser of such assets or allegingrelated erosion of revenue or loss of customers.
If our counterparties are unable to fulfill their financial and other obligations to us, our business and results of operations may be affected adversely.
Any downturn in economic conditions or other business factors could threaten the financial health of our counterparties, including companies with which we have entered into licensing and/or settlement agreements, and their ability to fulfill their financial and other obligations to us. Such financial pressures on our counterparties may eventually lead to bankruptcy proceedings or other attempts to avoid financial obligations that are due to us. Because bankruptcy courts have the power to
54


modify or cancel contracts of the petitioner which remain subject to future performance and alter or discharge payment obligations related to pre-petition debts, we may receive less than all of the payments that we have violatedwould otherwise be entitled to receive from any such counterparty as a result of bankruptcy proceedings.
If we are unable to attract and retain qualified personnel globally, our business and operations could suffer.
Our success is dependent upon our ability to identify, attract, compensate, motivate and retain qualified personnel, especially engineers, senior management and other key personnel. The loss of the termsservices of an open source license. Litigationany key employees could be costlydisruptive to our development efforts, business relationships and strategy, and could cause our business and operations to suffer.
All of our officers and other U.S. employees are at-will employees, which means they may terminate their employment relationship with us at any time, and their knowledge of our business and industry would be extremely difficult to replace. Any changes in our senior management team in particular, even in the ordinary course of business, may be disruptive to our business. While we seek to manage these transitions carefully, including by establishing strong processes and procedures and succession planning, such changes may result in a loss of institutional knowledge and cause disruptions to our business. If our senior management team fails to work together effectively or execute our plans and strategies on a timely basis as a result of management turnover or otherwise, our business could be harmed.
Our future success depends in large part upon the continued service and enhancement of our management team and our employees. If there are further changes in management, such changes could be disruptive and could negatively affect our sales, operations, culture, future recruiting efforts and strategic direction. Competition for qualified executives is intense, and if we are unable to compensate our key talent appropriately and continue expanding our management team, or successfully integrate new additions to our management team in a manner that enables us to defend,scale our business and operations effectively, our ability to operate effectively and efficiently could be limited or negatively impacted. In addition, changes in key management positions may temporarily affect our financial performance and results of operations as new management becomes familiar with our business, processes and strategy. The loss of any of our key personnel, or our inability to attract, integrate and retain qualified employees who join us organically and through acquisitions, could require us to dedicate significant financial and other resources to such personnel matters, disrupt our operations and seriously harm our operations and business.
Our operations are subject to risks of natural disasters, acts of war, terrorism, widespread illness or security breaches or incidents at our domestic and international locations, any one of which could result in a business stoppage and negatively affect our operating results.
Our business operations depend on our ability to maintain and protect our facilities, computer systems and personnel, which are primarily located in the San Francisco Bay Area in the United States, Canada, the Netherlands, France, Bulgaria, Taiwan and India. The San Francisco Bay Area is in close proximity to known earthquake fault zones and sites of recent historic wildfires. Our facilities and transportation for our employees are susceptible to damage from earthquakes and other natural disasters such as fires, floods, droughts, extreme temperatures, and similar events. Should a catastrophe disable our facilities, we do not have readily available alternative facilities from which we could conduct our business, so any resultant work stoppage could have a negative effect on our operating resultsresults. We also rely on our network infrastructure and financialtechnology systems for operational support and business activities which are subject to physical and cyber damage, and also susceptible to other related vulnerabilities common to networks and computer systems.

The COVID-19 pandemic or other disease outbreak, may continue to devote additional researchadversely affect the economies and development resources to changefinancial markets of many countries, resulting in an economic downturn that may impact overall technology spending, adversely affecting demand for our solutions. In addition, if we were to combineproducts and impacting our proprietary software solutions with open source softwareoperating results. Furthermore, such disruption in certain manners, we could, under certain open source licenses, be required to publicly release the source code of our proprietary software solutions. If we inappropriately use open source software, weglobal financial markets may be required to re-engineer our solutions, discontinue the sale of our solutions, release the source code of our proprietary software to the public at no cost or take other remedial actions. There is a risk that open source licenses could be construed in a way that could impose unanticipated conditions or restrictions onreduce our ability to commercializeaccess capital or our solutions,customers’ ability to pay us for past or future purchases, which could adverselynegatively affect our liquidity.
We and our suppliers could be affected by laws and regulations enacted in response to concerns regarding climate change, conflict minerals, responsible sourcing practices, public health crises, contagious disease outbreaks, or other matters, which could limit the supply of our materials and/or increase the cost. Environmental regulations could limit our ability to procure or use certain chemicals or materials in our operations or products. In addition, disruptions in transportation lines could delay our receipt of materials.
Acts of terrorism, climate-change related risk, widespread illness, or global pandemics, war and any event that causes failures or interruption in our network infrastructure and technology systems could have a negative effect at our international and domestic facilities and could harm our business, financial condition, and operating results.
55


We rely upon the accuracy of our customers’ recordkeeping, and any inaccuracies or payment disputes for amounts owed to us under our licensing agreements may harm our results of operations.
Many of our license agreements require our customers to document the manufacture and sale of products that incorporate our technology and report this data to us on a quarterly basis. While licenses with such terms give us the right to audit books and records of our customers to verify this information, audits rarely are undertaken because they can be expensive, time consuming, and potentially detrimental to our ongoing business relationship with our customers. Therefore, we typically rely on the accuracy of the reports from customers without independently verifying the information in them. Our failure to audit our customers’ books and records may result in our receiving more or less royalty revenue than we are entitled to under the terms of our license agreements. If we conduct royalty audits in the future, such audits may trigger disagreements over contract terms with our customers and such disagreements could hamper customer relations, divert the efforts and attention of our management from normal operations and impact our business operations and financial condition.

We are subject to increased inventory risks and costs because we build our products based on forecasts provided by customers before receiving purchase orders for the product.
Our business and operating results could be harmed if we undertake any restructuring activities.

From time to time, we may undertake restructurings of our business, such as the restructuringincluding discontinuing certain products, services and plan of termination that we undertooktechnologies and planned reductions in the fourth quarter of 2015.force. There are several factors that could cause restructurings to have adverse effects on our business, financial condition and results of operations. These include potential disruption of our operations, the development of our technology, the deliveries to our customers and other aspects of our business. Loss of sales, service and engineering talent, in particular, could damage our business. Any restructuring would require substantial management time and attention and may divert management from other important work. Employee reductions or other restructuring activities also would cause us to incur restructuring and related expenses such as severance expenses. Moreover, we could encounter delays in executing any restructuring plans, which could cause further disruption and additional unanticipated expense.
Problems with our information systems could interfere with our business and could adversely impact our operations.
We rely on our information systems and those of third parties for fulfilling licensing and contractual obligations, processing customer orders, delivering products, providing services and support to our customers, billing and tracking our customer orders, performing accounting operations and otherwise running our business. If our systems fail, our disaster and data recovery planning and capacity may prove insufficient to enable timely recovery of important functions and business records. Any disruption in our information systems and those of the third parties upon whom we rely could have a significant impact on our business. For example, in the third quarter of 2023, we commenced operating a new ERP system. Any failures of this system to operate as intended could impact our ability to timely and accurately manage our business and publicly report our financial results. Additionally, our information systems may not support new business models and initiatives and significant investments could be required in order to upgrade them. For example, in connection with our adoption of the Standard, we plan to augment our systems with new revenue accounting software, utilizing internal and third party resources. Delays in adapting our information systems to address new business models and accounting standards could limit the success or result in the failure of such initiatives and impair the effectiveness of our internal controls. Even if we do not encounter these adverse effects, the implementation of these enhancements may be much more costly than we anticipated. If we are unable to successfully implement the information systems enhancements as planned, our operating results could be negatively impacted.
Risks RelatedCertain software we use is from open source code sources, which, under certain circumstances, may lead to Capitalization Mattersunintended consequences and, Corporate Governancetherefore, could materially adversely affect our business, financial condition, operating results and cash flow.
The price ofWe use open source software in our common stock mayservices and we intend to continue to fluctuate.
Our common stock is listed on The NASDAQ Global Select Market under the symbol “RMBS.” The trading price of our common stock has at times experienced price volatility and may continue to fluctuate significantly in response to various factors, some of which are beyond our control.  Some of these factors include:
any progress, or lack of progress, real or perceived,use open source software in the developmentfuture. From time to time, there have been claims challenging the ownership of productsopen source software against companies that incorporate our innovations and technology companies' acceptanceopen source software into their products or alleging that these companies have violated the terms of our products, including the results of our efforts to expand into new target markets;
our signing or not signing new licenses and the loss of strategic relationships with any customer;
announcements of technological innovations or new products by us, our customers or our competitors;
changes in our strategies, including changes in our licensing focus and/or acquisitions of companies with business models or target markets different from our own;
positive or negative reports by securities analysts as to our expected financial results and business developments;
developments with respect to patents or proprietary rights and other events or factors;
new litigation and the unpredictability of litigation results or settlements; and
issuance of additional securities by us, including in acquisitions.
In addition, the stock market in general, and prices for companies in our industry in particular, have experienced extreme volatility that often has been unrelated to the operating performance of such companies. These broad market and industry fluctuations may adversely affect the price of our common stock, regardless of our operating performance.
We have outstanding senior convertible notes in an aggregate principal amount totaling $138.0 million. Because these notes are convertible into shares of our common stock, volatility or depressed prices of our common stockopen source license. As a result, we could have a similar effect on the trading price of such notes. In addition, the existence of these notes may encourage short selling in our common stock by market participants because the conversion of the notes could depress the price of our common stock.

We have been party to, and may in the future be subject to lawsuits relatingby parties claiming ownership of what we believe to securities law matters which may result in unfavorable outcomesbe open source software or alleging that we have violated the terms of an open source license. Litigation could be costly for us to defend, have a negative effect on our operating results and significant judgments, settlements and legal expenses which could cause our business, financial condition or require us to devote additional research and results of operationsdevelopment resources to suffer.
We andchange our solutions. In addition, if we were to combine our proprietary software solutions with open source software in certain manners, we could, under certain open source licenses, be required to publicly release the source code of our current and former officers and directors, as well asproprietary software solutions. If we inappropriately use open source software, we may be required to re-engineer our current auditors, were subject from 2006 to 2011 to several stockholder derivative actions, securities fraud class actions and/or individual lawsuits filed in federal court against us and certainsolutions, discontinue the sale of our current and former officers and directors. The complaints generally allegedsolutions, release the source code of our proprietary software to the public at no cost or take other remedial actions. There is a risk that the defendants violated the federal and state securities laws and stated state law claims for fraud and breach of fiduciary duty. Although to date these complaints have either been settledopen source licenses could be construed in a way that could impose unanticipated conditions or dismissed, the amount of time to resolve any future lawsuits is uncertain, and these matters could require significant management and financial resources. Unfavorable outcomes and significant judgments, settlements and legal expenses in litigation related to any future securities law claims could have material adverse impactsrestrictions on our business, financial condition, results of operations, cash flows and the trading price ofability to commercialize our common stock.

In the future, we may fail to adjustmaintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material misstatements of our businessconsolidated financial statements or cause us to respond to competitive pressures and to obtain sufficient funds to satisfy our future research and development needs, to protect and enforce our intellectual property, andfail to meet other needs.our periodic reporting obligations.
We have material indebtedness. In August 2013, we issued $138.0 million aggregate principal amount of our 2018 Notes which remain outstanding. The degree to whichIf we are leveraged could have negative consequences, including, but not limited to, the following:
we may be more vulnerable to economic downturns, less able to withstand competitive pressures and less flexible in responding to changing business and economic conditions;
our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, litigation, general corporate or other purposes may be limited;
a substantial portion of our cash flows from operations in the future may be required for the payment of the principal amount of our existing indebtedness when it becomes due at maturity in August 2018; and
we may be required to make cash payments upon any conversion of the 2018 Notes, which would reduce our cash on hand.

A failure to comply with the covenantsrequirements of the Sarbanes-Oxley Act or if we are unable to maintain effective internal control over financial reporting and other provisionsdisclosure controls and procedures, we may not be able to produce timely and accurate financial statements or guarantee that information required to be disclosed by us in the reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. In connection with the audit of our debt instrumentsconsolidated financial statements as of and for the year ended December 31, 2020, we and our independent registered public accounting firm identified a material weakness in our internal control over financial reporting that impacted our consolidated financial statements and related disclosures as of and for the years ended December 31, 2020 and 2019, and revised our consolidated financial statements for the year ended December 31, 2018. While we believe this material weakness has been remediated, we cannot assure you that we have identified all of our existing material weaknesses, or that we will not in the future have additional material weaknesses. Any failure of our internal control over financial reporting or disclosure controls and procedures could result in eventsmaterial misstatements of default under such instruments,our consolidated financial statements, which could permit acceleration of all ofcause our outstanding 2018 Notes. Any required repurchase of the 2018 Notes as a result of a fundamental change or acceleration of the 2018 Notes would reduce our cash on hand such that we would not have those funds available for useinvestors to lose confidence in our business.
If we are at any time unable to generate sufficient cash flows from operations to service our indebtedness when payment is due, we may be required to attempt to renegotiate the terms of the instruments relating to the indebtedness, seek to refinance all or a portion of the indebtedness or obtain additional financing. There can be no assurance that we will be able to successfully renegotiate such terms, that any such refinancing would be possible or that any additional financing could be obtained on terms that are favorable or acceptable to us.
Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses.
Changing laws, regulations and standards relating to corporate governance and public disclosure have historically created uncertainty for companies such as ours. Any new or changed laws, regulations and standards are subject to varying interpretations due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.
Our certificate of incorporation and bylaws, Delaware law, our outstanding convertible notes and certain other agreements contain provisions that could discourage transactions resulting in a change in control, which may negatively affectpublicly reported information, cause the market price of our common stock.
Our certificate of incorporation, our bylaws and Delaware law contain provisions that might enable our managementstock to discourage, delay or prevent a change in control. In addition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock. Pursuant to such provisions:
our board of directors is authorized, without prior stockholder approval, to create and issue preferred stock, commonly referred to as “blank check” preferred stock, with rights senior to those of common stock, which means that a stockholder rights plan could be implemented by our board;
our board of directors is staggered into two classes, only one of which is elected at each annual meeting;
stockholder action by written consent is prohibited;

nominations for election to our board of directors and the submission of matters to be acted upon by stockholders at a meeting are subject to advance notice requirements;
certain provisions in our bylaws and certificate of incorporation such as notice to stockholders, the ability to call a stockholder meeting, advance notice requirements and action of stockholders by written consent may only be amended with the approval of stockholders holding 66 2/3% of our outstanding voting stock;
our stockholders have no authority to call special meetings of stockholders; and
our board of directors is expressly authorized to make, alter or repeal our bylaws.
We are also subject to Section 203 of the Delaware General Corporation Law, which provides, subject to enumerated exceptions, that if a person acquires 15% or more of our outstanding voting stock, the person is an “interested stockholder” and may not engage in any “business combination” with us for a period of three years from the time the person acquired 15% or more of our outstanding voting stock.
Certain provisions of our outstanding 2018 Notes could make it more difficult or more expensive for a third party to acquire us. Upon the occurrence of certain transactions constituting a fundamental change, holders of such 2018 Notes will have the right, at their option, to requiredecline, expose us to repurchase, at a cash repurchase price equal to 100%sanctions or investigations by the SEC or other regulatory authorities, or impact our results of the principal amount plus accrued and unpaid interest on such 2018 Notes, all or a portion of their 2018 Notes. We may also be required to increase the conversion rate of such 2018 Notes in the event of certain fundamental changes.operations.
Unanticipated changes in our tax rates or in the tax laws, treaties and regulations could expose us to additional income tax liabilities, which could affect our operating results and financial condition.
We are subject to income taxes in both the United States and various foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes and, in the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain. Our effective tax rate could be adversely affected by several factors, many of which are outside of our control, including changes in the mix of earnings and losses in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in tax laws, rates, treaties and regulations as well as other factors.or the interpretation of the same, changes to the financial accounting rules for income taxes, the outcome of current and future tax audits, examinations or administrative appeals and certain non-deductible expenses. Our tax determinations are regularly subject to audit by tax authorities and developments in those audits could adversely affect our income tax provision, and we are currently undergoing such audits of certain of our tax returns. Although we believe that our tax estimates are reasonable, the final determination of tax audits or tax disputes may be different from what is reflected in our historical income tax provisions, which could affect our operating results.
The Organization for Economic Cooperation and Development has proposed imposing a 15% global minimum tax, and the Council of the European Union adopted this proposal for implementation by member states by December 31, 2023. Further, the United States has recently enacted the Inflation Reduction Act, which includes, among other changes, a 1% excise tax on certain stock repurchases and a 15% alternative minimum tax on adjusted financial statement income. If we are subject to additional tax liabilities, our financial performance may be adversely affected. In addition, many jurisdictions are actively considering changes to existing tax laws or have proposed or enacted new laws that could increase our tax obligations in countries where we do business or cause us to change the way we operate our business. Any of these developments or changes in federal, state, or international tax laws or tax rulings could adversely affect our effective tax rate and our operating results.
Risks Associated with Litigation, Regulation and Business Risks RelatedOur Intellectual Property
We are subject to various government restrictions and regulations, including on the sale of products and services that use encryption and other technology and those related to privacy and other consumer protection matters.
Various countries have adopted controls, license requirements and restrictions on the export, import and use of products or services that contain encryption technology. In addition, governmental agencies have proposed additional requirements for encryption technology, such as requiring the escrow and governmental recovery of private encryption keys. Restrictions on the sale or distribution of products or services containing encryption technology may impact our ability to license data security technologies to the manufacturers and providers of such products and services in certain markets or may require us or our customers to make changes to the licensed data security technology that is embedded in such products to comply with such restrictions. Government restrictions, or changes to the products or services of our customers to comply with such restrictions, could delay or prevent the acceptance and use of such customers’ products and services. In addition, the United States and other countries have imposed export controls that prohibit the export of encryption and other technology to certain countries, entities and individuals. Our failure to comply with export and use regulations concerning encryption technology could subject us to sanctions and penalties, including fines, and suspension or revocation of export or import privileges. Additionally, climate change concerns and the potential resulting environmental impact may result in new environmental, health, and safety laws and regulations that may affect us, our suppliers, and our customers. Such laws or regulations could cause us to incur additional direct costs for compliance, as well as increased indirect costs resulting from our customers, suppliers, or both incurring
57


additional compliance costs that are passed on to us. These costs may adversely impact our results of operations and financial condition.
We are subject to a variety of laws and regulations in the United States, the European Union and other countries that involve, for example, user privacy, data protection and security, content and consumer protection. For example, in 2016, a new EU data protection regime, the General Data Protection Regulation (“GDPR”) was adopted, with it fully effective on May 25, 2018. The GDPR includes significant penalties for noncompliance, which may result in monetary penalties of up to the higher of €20 million or 4% of a group’s worldwide turnover for the preceding financial year for the most serious violations. The United Kingdom’s version of the GDPR, which it maintains along with its Data Protection Act, also provides for substantial penalties that, for the most serious violations, can go up to the greater of £17.5 million or 4% of a group’s worldwide turnover for the preceding financial year. In the United States, California enacted the California Consumer Privacy Act (“CCPA”), which became effective on January 1, 2020. The CCPA includes a framework with potentially severe statutory damages and private rights of action. Moreover, a new privacy law, the California Privacy Rights Act (“CPRA”), was approved by California voters in November 2020. The CPRA significantly modifies the CCPA, effective as of January 1, 2023. Numerous other states have passed laws that share similarities with the CCPA and CPRA, and other states are considering such legislation. The U.S. federal government also is contemplating federal privacy legislation. The GDPR and CCPA, and new and evolving laws such as the CPRA, and other future changes in laws or regulations relating to cross-border data transfer, data localization, and other aspects of privacy, data protection and information security may require us to modify our existing practices with respect to the collection, use, disclosure and other processing of data. The GDPR, CCPA, and other existing and proposed laws and regulations can be costly and challenging to comply with and can delay or impede the development of new products, result in negative publicity, increase our operating costs and subject us to claims or other remedies.
We are subject to disclosure and reporting requirements for companies that use “conflict” minerals mined from the Democratic Republic of Congo and adjoining countries in their products, whether or not these products are manufactured by third parties. These requirements could affect the sourcing and availability of minerals that are used in the manufacture of our products. We have to date incurred costs and expect to incur significant additional costs associated with complying with the disclosure requirements, including for example, due diligence in regard to the sources of any conflict minerals used in our products, in addition to the cost of remediation and other changes to products, processes, or sources of supply as a consequence of such verification activities. Additionally, we may face reputational challenges with our customers and other stakeholders if we are unable to sufficiently verify the origins of all minerals used in our products through the due diligence procedures that we implement. We may also face challenges with government regulators and our customers and suppliers if we are unable to sufficiently verify that the metals used in our products are conflict free.
Litigation and government proceedings could affect our business in materially negative ways.
We may be subject to legal claims or regulatory matters involving consumer, stockholder, employment, competition, IP and other issues on a global basis. Litigation can be lengthy, expensive and disruptive to our Intellectual Propertyoperations, and results cannot be predicted with certainty. An adverse decision could include monetary damages or, in cases for which injunctive relief is sought, an injunction prohibiting us from manufacturing or selling one or more of our products or technologies. If we were to receive an unfavorable ruling on a matter, our business, operating results or financial condition could be materially harmed.
We have in the past, and may in the future, become engaged in litigation stemming from our efforts to protect and enforce our patents and intellectual propertyIP and make other claims, which could adversely affect our intellectual propertyIP rights, distract our management and cause substantial expenses and declines in our revenue and stock price.
We seek to diligently protect our intellectual propertyIP rights and will continue to do so. While we are not currently involved in intellectual propertyIP litigation, any future litigation, whether or not determined in our favor or settled by us, would be expected to be costly, may cause delays applicable to our business (including delays in negotiating licenses with other actual or potential customers), would be expected to tend to discourage future design partners, would tend to impair adoption of our existing technologies and would divert the efforts and attention of our management and technical personnel from other business operations. In addition, we may be unsuccessful in any litigation if we have difficulty obtaining the cooperation of former employees and agents who were involved in our business during the relevant periods related to our litigation and are now needed to assist in cases or testify on our behalf. Furthermore, any adverse determination or other resolution in litigation could result in our losing certain rights beyond the rights at issue in a particular case, including, among other things: our being effectively barred from suing others for violating certain or all of our intellectual propertyIP rights; our patents being held invalid or unenforceable or not infringed; our being subjected to significant liabilities; our being required to seek licenses from third parties; our being prevented from licensing our patented technology; or our being required to renegotiate with current customers on a temporary or permanent basis.
58


From time to time, we are subject to proceedings by government agencies that may result in adverse determinations against us and could cause our revenue to decline substantially.
An adverse resolution by or with a governmental agency could result in severe limitations on our ability to protect and license our intellectual property,IP, and could cause our revenue to decline substantially. Third parties have and may attempt to use adverse findings by a government agency to limit our ability to enforce or license our patents in private litigations,litigation, to challenge or otherwise act against us with respect to such government agency proceedings.

Further, third parties have sought and may seek review and reconsideration of the patentability of inventions claimed in certain of our patents by the U.S. Patent and Trademark Office (“USPTO”) and/or the European Patent Office (the “EPO”).

Any re-examination or inter partes review proceedings may be reviewedinitiated by the USPTO'sUSPTO’s Patent Trial and Appeal Board (“PTAB”). The PTAB and the related former Board of Patent Appeals and Interferences have previously issued decisions in a few cases, finding some challenged claims of Rambus'our patents to be valid, and others to be invalid. Decisions of the PTAB are subject to further USPTO proceedings and/or appeal to the Court of Appeals for the Federal Circuit. A final adverse decision, not subject to further review and/or appeal, could invalidate some or all of the challenged patent claims and could also result in additional adverse consequences affecting other related U.S. or European patents, including in any intellectual propertyIP litigation. If a sufficientsignificant number of such patents are impaired, our ability to enforce or license our intellectual propertyIP would be significantly weakened and could cause our revenue to decline substantially.

The pendency of any governmental agency acting as described above may impair our ability to enforce or license our patents or collect royalties from existing or potential customers, as any litigation opponents may attempt to use such proceedings to delay or otherwise impair any pending cases and our existing or potential customers may await the final outcome of any proceedings before agreeing to new licenses or to paying royalties.

Litigation or other third-party claims of intellectual propertyIP infringement could require us to expend substantial resources and could prevent us from developing or licensing our technology on a cost-effective basis.
Our research and development and product programs are in highly competitive fields in which numerous third parties have issued patents and patent applications with claims closely related to the subject matter of our programs. We haveand/or our customers, also been named in the past, and may in the future be named as a defendant in lawsuits claiming that our technology infringes upon the intellectual propertyIP rights of third parties. As we develop additional products and technology, we may face claims of infringement of various patents and other intellectual propertyIP rights by third parties. In the event of a third-party claim or a successful infringement action against us, we may be required to pay substantial damages, to stop developing and licensing our infringing technology, to develop non-infringing technology, and to obtain licenses, which could result in our paying substantial royalties or our granting of cross licenses to our technologies. We may not be able to obtain licenses from other parties at a reasonable cost, or at all, which could cause us to expend substantial resources, or result in delays in, or the cancellation of, new products. Moreover, customers and/or suppliers of our products may seek indemnification for alleged infringement of intellectual propertyIP rights. We could be liable for direct and consequential damages and expenses including attorneys’ fees. A future obligation to indemnify our customers and/or suppliers may harm our business, financial condition and operating results.
If we are unable to protect our inventions successfully through the issuance and enforcement of patents, our operating results could be adversely affected.
We have an active program to protect our proprietary inventions through the filing of patents. There can be no assurance, however, that:
any current or future U.S. or foreign patent applications will be approved and not be challenged by third parties;
our issued patents will protect our intellectual propertyIP and not be challenged by third parties;
the validity of our patents will be upheld;
our patents will not be declared unenforceable;
the patents of others will not have an adverse effect on our ability to do business;
Congress or the U.S. courts or foreign countries will not change the nature or scope of rights afforded patents or patent owners or alter in an adverse way the process for seeking or enforcing patents;
changes in law will not be implemented, or changes in interpretation of such laws will occur, that will affect our ability to protect and enforce our patents and other intellectual property;IP;
new legal theories and strategies utilized by our competitors will not be successful;
others will not independently develop similar or competing chip interfaces or design around any patents that may be issued to us; or
59


factors such as difficulty in obtaining cooperation from inventors, pre-existing challenges or litigation, or license or other contract issues will not present additional challenges in securing protection with respect to patents and other intellectual propertyIP that we acquire.
If any of the above were to occur, our operating results could be adversely affected.
Furthermore, recent patent reform legislation, such as the Leahy-Smith America Invents Act, could increase the uncertainties and costs surrounding the prosecution of any patent applications and the enforcement or defense of our licensed patents. The federal courts, the USPTO, the Federal Trade Commission, and the U.S. International Trade Commission have also recently taken certain actions and issued rulings that have been viewed as unfavorable to patentees. While we cannot predict what form any new patent reform laws or regulations may ultimately take, or what impact recent or future reforms may have on our business, any laws or regulations that restrict or negatively impact our ability to enforce our patent rights against third parties could have a material adverse effect on our business.

In addition, our patents will continue to expire according to their terms, with expected expiration dates ranging from 20172023 to 2038.2042. Our failure to continuously develop or acquire successful innovations and obtain patents on those innovations could significantly harm our business, financial condition, results of operations, or cash flows.
Our inability to protect the IP we create and own the intellectual property we create would cause our business to suffer.
We rely primarily on a combination of license, development and nondisclosure agreements, trademark, trade secret and copyright law and contractual provisions to protect our non-patentable intellectual propertyIP rights. If we fail to protect these intellectual propertyIP rights, our customers and others may seek to use our technology without the payment of license fees and royalties, which could weaken our competitive position, reduce our operating results and increase the likelihood of costly litigation. The growth of our business depends in part on the use of our intellectual propertyIP in the products of third partythird-party manufacturers, and our ability to enforce intellectual propertyIP rights against them to obtain appropriate compensation. In addition, effective trade secret protection may be unavailable or limited in certain foreign countries. Although we intend to protect our rights vigorously, if we fail to do so, our business will suffer.

Effective protection of trademarks, copyrights, domain names, patent rights, and other intellectual propertyIP rights is expensive and difficult to maintain, both in terms of application and maintenance costs, as well as the costs of defending and enforcing those rights. The efforts we have taken to protect our intellectual propertyIP rights may not be sufficient or effective. Our intellectual propertyIP rights may be infringed, misappropriated, or challenged, which could result in them being narrowed in scope or declared invalid or unenforceable. In addition, the laws or practices of certain countries do not protect our proprietary rights to the same extent as do the laws of the United States. Significant impairments of our intellectual propertyIP rights, and limitations on our ability to assert our intellectual propertyIP rights against others, could have a material and adverse effect on our business.

Third parties may claim that our products or services infringe on their intellectual propertyIP rights, exposing us to litigation that, regardless of merit, may be costly to defend.

Our success and ability to compete are also dependent upon our ability to operate without infringing upon the patent, trademark and other intellectual propertyIP rights of others. Third parties may claim that our current or future products or services infringe upon their intellectual propertyIP rights. Any such claim, with or without merit, could be time consuming, divert management’s attention from our business operations and result in significant expenses. We cannot assure you that we would be successful in defending against any such claims. In addition, parties making these claims may be able to obtain injunctive or other equitable relief affecting our ability to license the products that incorporate the challenged intellectual property.IP. As a result of such claims, we may be required to obtain licenses from third parties, develop alternative technology or redesign our products. We cannot be sure that such licenses would be available on terms acceptable to us, if at all. If a successful claim is made against us and we are unable to develop or license alternative technology, our business, financial condition, operating results and cash flows could be materially adversely affected.

We rely upon the accuracy of our customers' recordkeeping, and any inaccuracies or payment disputes for amounts owed to us under our licensing agreements may harm our results of operations.

Many of our license agreements require our customers to document the manufacture and sale of products that incorporate our technology and report this data to us on a quarterly basis. While licenses with such terms give us the right to audit books and records of our customers to verify this information, audits rarely are undertaken because they can be expensive, time consuming, and potentially detrimental to our ongoing business relationship with our customers. Therefore, we typically rely on the accuracy of the reports from customers without independently verifying the information in them. Our failure to audit our customers' books and records may result in our receiving more or less royalty revenue than we are entitled to under the terms of our license agreements. If we conduct royalty audits in the future, such audits may trigger disagreements over contract terms with our customers and such disagreements could hamper customer relations, divert the efforts and attention of our management from normal operations and impact our business operations and financial condition.
Any dispute regarding our intellectual propertyproducts or services may require us to indemnify certain customers, the cost of which could severely hamper our business operations and financial condition.
In any potential dispute involving our patents or other intellectual property,products, our customers could also become the target of litigation. While we generally do not indemnify our customers, someSome of our agreements provide for indemnification, and some require us to provide technical support and information to a customer that is involved in litigation involving use of our technology. In addition, we may be exposed to indemnification obligations, risks and liabilities that were unknown at the time of acquisitions, including with respect tothat we acquired assets or businesses for our acquisitions of SCS, the assets of the Snowbush IP group and the Memory Interconnect Business, and we may agree to indemnify others in the future.operations. Any of these indemnification and support

obligations could result in substantial and material expenses. In addition to the time and expense required for us to indemnify or supply such support to our customers, a customer'scustomer’s development, marketing and sales of licensed semiconductors, lighting, mobile communications and data security technologies could be severely disrupted or shut down as a result of litigation, which in turn could severely hamper our business operations and financial condition as a result of lower or no royalty payments.
60


Warranty, service level agreement and product liability claims brought against us could cause us to incur significant costs and adversely affect our operating results, as well as our reputation and relationships with customers.
We may from time to time be subject to warranty, service level agreement and product liability claims with regard to product performance and our services. We could incur material losses as a result of warranty, support, repair or replacement costs in response to customer complaints or in connection with the resolution of contemplated or actual legal proceedings relating to such claims. In addition to potential losses arising from claims and related legal proceedings, warranty and product liability claims could affect our reputation and our relationship with customers. We generally attempt to limit the maximum amount of indemnification or liability that we could be exposed to under our contracts, however, this is not always possible.
We have been party to, and may in the future be subject to, lawsuits relating to securities law matters which may result in unfavorable outcomes and significant judgments, settlements and legal expenses which could cause our business, financial condition and results of operations to suffer.
We and certain of our current and former officers and directors, as well as our current independent auditors, have been subject to several stockholder derivative actions, securities fraud class actions and/or individual lawsuits filed in federal court. The complaints generally alleged that the defendants violated the federal and state securities laws and stated state law claims for fraud and breach of fiduciary duty. Although to date these complaints have either been settled or dismissed, the amount of time to resolve any future lawsuits is uncertain, and these matters could require significant management and financial resources. Unfavorable outcomes and significant judgments, settlements and legal expenses in litigation related to any future securities law claims could have material adverse impacts on our business, financial condition, results of operations, cash flows and the trading price of our common stock.
Participation in standards setting organizations may subject us to IP licensing requirements or limitations that could adversely affect our business and prospects.
In the course of our participation in the development of emerging standards for some of our present and future products, we may be obligated to grant to all other participants a license to our patents that are essential to the practice of those standards on reasonable and non-discriminatory, or RAND, terms. As a result of such obligations, we may be required to license our patents or other IP to others in the future, which could limit the value of the patents and effectiveness of our patents against competitors.
Risks Associated with Capitalization Matters
The price of our common stock may continue to fluctuate.
Our common stock is listed on The Nasdaq Global Select Market under the symbol “RMBS.” The trading price of our common stock has at times experienced price volatility and may continue to fluctuate significantly in response to various factors, some of which are beyond our control. Some of these factors include:
any progress, or lack of progress, real or perceived, in the development of products that incorporate our innovations and technology companies’ acceptance of our products, including the results of our efforts to expand into new target markets;
our signing or not signing new licenses or renewing existing licenses, and the loss of strategic relationships with any customer;
announcements of technological innovations or new products by us, our customers or our competitors;
changes in our strategies, including changes in our licensing focus and/or acquisitions or dispositions of companies or businesses with business models or target markets different from our core;
changes in macroeconomic conditions, increased risk of recession, and geopolitical issues, including the effects of tensions between China and Taiwan;
positive or negative reports by securities analysts as to our expected financial results and business developments;
developments with respect to patents or proprietary rights and other events or factors;
new litigation and the unpredictability of litigation results or settlements;
repurchases of our common stock on the open market;
issuance of additional securities by us, including in acquisitions, or large cash payments, including in acquisitions; and
changes in accounting pronouncements.
In addition, the stock market in general, and prices for companies in our industry in particular, have experienced extreme volatility that often has been unrelated to the operating performance of such companies. The trading price of our common stock may fluctuate widely due to various factors, including, but not limited to, actual or anticipated fluctuations in our financial
61


condition and operating results, changes in financial forecasts or estimates by us or financial or other market estimates and ratings by securities and other analysts, changes in our capital structure, including issuance of additional debt or equity to the public, interest rate changes, regulatory changes, news regarding our products or products of our competitors, and broad market and industry fluctuations. While the trading price of our common stock has been trending upward, there is no guarantee that the trading price will continue to increase.
Investors in our common stock may not realize any return on their investment in us and may lose some or all of their investment. Volatility in the trading price of our common stock could also result in the filing of securities class action litigation matters, which could result in substantial costs and the diversion of management time and resources.
Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses.
Changing laws, regulations and standards relating to corporate governance and public disclosure have historically created uncertainty for companies such as ours. Any new or changed laws, regulations and standards are subject to varying interpretations due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.
Our amended and restated certificate of incorporation and amended and restated bylaws, Delaware law, and certain other agreements contain provisions that could discourage transactions resulting in a change in control, which may negatively affect the market price of our common stock.
Our amended and restated certificate of incorporation, our amended and restated bylaws and Delaware law contain provisions that might enable our management to discourage, delay or prevent a change in control. In addition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock. Pursuant to such provisions:
our board of directors is authorized, without prior stockholder approval, to create and issue preferred stock, commonly referred to as “blank check” preferred stock, with rights senior to those of common stock, which means that a stockholder rights plan could be implemented by our board;
our board of directors is staggered into two classes, only one of which is elected at each annual meeting;
stockholder action by written consent is prohibited;
nominations for election to our board of directors and the submission of matters to be acted upon by stockholders at a meeting are subject to advance notice requirements, including compliance with the “universal proxy rules” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings;
certain provisions in our amended and restated certificate of incorporation and amended and restated bylaws, such as notice to stockholders, the ability to call a stockholder meeting, advance notice requirements and action of stockholders by written consent may only be amended with the approval of stockholders holding 66 2/3% of our outstanding voting stock;
our stockholders have no authority to call special meetings of stockholders; and
our board of directors is expressly authorized to make, alter or repeal our bylaws.
We are also subject to Section 203 of the Delaware General Corporation Law, which provides, subject to enumerated exceptions, that if a person acquires 15% or more of our outstanding voting stock, the person is an “interested stockholder” and may not engage in any “business combination” with us for a period of three years from the time the person acquired 15% or more of our outstanding voting stock.
Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware and the federal district courts of the United States will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware or the federal district court for the District of Delaware) is the exclusive forum for the following (except for any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than such court or for which such court does not have subject matter jurisdiction):
any derivative action or proceeding brought on behalf of us;
62


any action asserting a claim of breach of a fiduciary duty;
any action asserting a claim against us arising under the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws (as either may be amended from time to time); and
any action asserting a claim against us that is governed by the internal affairs doctrine.
This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the U.S. federal courts have exclusive jurisdiction.
Our amended and restated bylaws further provide that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.
These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to these provisions. There is uncertainty as to whether a court would enforce such provisions, and the enforceability of similar choice of forum provisions in other companies’ charter documents has been challenged in legal proceedings. It is possible that a court could find these types of provisions to be inapplicable or unenforceable, and if a court were to find either exclusive-forum provision in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
Share Repurchase Program
On January 21, 2015,October 29, 2020, our Board approved a new share repurchase program authorizing the repurchase of up to an aggregate of 20.0 million shares.shares (the “2020 Repurchase Program”). Share repurchases under the plan2020 Repurchase Program may be made through the open market, established plans or privately negotiated transactions in accordance with all applicable securities laws, rules, and regulations.
