2. Summary of Significant Accounting Policies
Basis of Presentation and Consolidation
The accompanying condensed consolidated balance sheet as of September 30, 2017,2020, the condensed consolidated statements of operations, the condensed consolidated statements of comprehensive (loss) income, and comprehensive incomethe condensed consolidated statements of stockholders’ equity for the three and nine months ended September 30, 20172020 and 2016,2019, and the condensed consolidated statements of cash flows for the nine months ended September 30, 20172020 and 20162019 are unaudited. The unaudited condensed consolidated financial statements included herein have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The condensed consolidated balance sheet data as of December 31, 20162019 was derived from the audited financial statements as of that date.
The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company’s financial position as of September 30, 2017,2020, the results of its operations for the three and nine months ended September 30, 20172020 and 2016,2019, the changes in comprehensive (loss) income and stockholders’ equity for the three and nine months ended September 30, 2020 and 2019, and the cash flows for the nine months ended September 30, 20172020 and 2016.2019. The results for the three and nine months ended September 30, 20172020 are not necessarily indicative of the results that may be expected for the year ending December 31, 20172020 or for any other future annual or interim period. Certain changes in presentation were made in the condensed consolidated financial statements for the three and nine months ended September 30, 2016,2019 to conform to the presentation for the three and nine months ended September 30, 2017.
The Company elected to early adopt Accounting Standards Update (ASU) 2016-09 in the fourth quarter of 2016 which requires the Company to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. The impact of adoption was the creation of deferred tax assets (“DTAs”) in the balance sheet and recognition of excess tax benefits in our provision for (benefit from) income taxes rather than paid-in capital for all periods in fiscal year 2016. The Company elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented.
Adoption of the new standard resulted in adjustments to our 2016 unaudited selected financial data previously reported in our Quarterly Report on Form 10-Q as follows:

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2016,2019, included in the Company’s Annual Report on Form 10-K. During the nine months ended September 30, 2017, the Company added accounting policies for goodwill, contingent consideration, intangible assets and non-marketable equity investments as described below. There have been no other changes to the Company’s significant accounting policies during the nine months ended September 30, 2017,2020, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.2019, other than the changes described below in connection with the adoption of the guidance under Accounting Standard Update (“ASU”) No. 2016-13.
The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and its wholly-owned subsidiaries.majority-owned subsidiary. The portion of equity and consolidated net income not attributable to the Company is considered non-controlling interest and is classified separately in the condensed consolidated financial statements. Any subsequent changes in the Company’s ownership interest while the Company retains its controlling interest in its majority-owned subsidiary will be accounted for as equity transactions. All intercompany accountsbalances and transactions have been eliminated.eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity accounts; disclosure of contingent assets and liabilities at the date of the financial statements; and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to marketable investments, provisionsallowances for doubtful accounts, sales return reserve,credit losses, the amount of variable consideration included in the transaction price, warranty reserve, valuation of inventories, useful lives of property and equipment, operating and financing lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, among others. The Company bases its 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 data. Actual results could differ from those estimates.
Goodwill
Goodwill represents the excess of the purchase price of an acquired business or assets over the fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but is tested for impairment at least annually, or more frequently if events or circumstances indicate the carrying value may no longer be recoverable and that an impairment loss may have occurred. The Company continues to operate as one segment, which is considered to be the sole reporting unit, and therefore goodwill is tested for impairment at the consolidated level.

Notes to Condensed Consolidated Financial Statements
(unaudited)

As of September 30, 2017, the Company’s goodwill is related to the acquisition of Crossmed S.p.a (“Crossmed”) during the third quarter of 2017. Refer to Note “5. Business Combination” and Note “6. Goodwill and Intangible Assets” for more information.
Contingent Consideration
Certain agreements the Company enters into, including business combinations and licensing agreements, involve the potential payment of future consideration that is contingent upon certain performance and revenue milestones being achieved. Contingent consideration related to business combinations is recorded at the acquisition date at fair value and is remeasured each reporting period with the change in fair value recognized within sales, general and administrative expense in the consolidated statements of operations and comprehensive income.
As of September 30, 2017, the Company’s contingent consideration related to the acquisition of Crossmed and intangible assets through a licensing agreement. For more information with respect to the fair value of contingent consideration, refer to Note “5. Business Combination” and Note “6. Goodwill and Intangible Assets,” respectively.
Intangible Assets
Intangible assets consist of intangibles acquired through a licensing arrangement and the acquisition of Crossmed during the third quarter of 2017.
Indefinite-lived intangible assets relate to payments and future milestone payments, which are probable and estimable, for an exclusive right to licensed technology. The acquired licensed technology is accounted for as an indefinite-lived intangible asset until it reaches technological feasibility, which is determined on the basis of obtaining regulatory approval to market and commercialize the underlying products. Upon the commercialization of the underlying product, the capitalized amount will be amortized over its estimated useful life. Indefinite-lived intangible assets will be tested for impairment at least annually, or more frequently if events or circumstances indicate their carrying value may no longer be recoverable and that an impairment loss may have occurred.
Finite-lived intangible assets are amortized using the straight-line method over the estimated economic useful lives of the assets, which is the period during which expected cash flows support the fair value of such intangible assets. The Company will review finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When such an event occurs, management will determine whether there has been impairment by comparing the anticipated undiscounted future net cash flows to the related asset group’s carrying value. If an asset is considered impaired, the asset will be written down to the determined fair value based on discounted cash flows. Refer to Note “6. Goodwill and Intangible Assets” for more information on the Company’s intangible assets.
Non-Marketable Equity Investments
Entities in which the Company has at least a 20%, but not more than a 50%, interest are accounted for under the equity method unless it is determined that the Company has a controlling financial interest in the entity, in which case the entity would be consolidated. Non-marketable equity investments are classified as investments and included in other non-current assets on the condensed consolidated balance sheet. The Company’s proportionate share of the operating results of its non-marketable equity method investments are recorded as profit or loss and included as a component of other expense, net,in the condensed consolidated statements of operations and comprehensive income. See Note “3. Investments and Fair Value of Financial Instruments” for further details.
Segments
The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company has one1 business activity: the design, development, manufacturing and marketing of innovative devices, and operates as one1 operating segment. The Company’s chief operating decision-maker, its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance.
Recently Adopted Accounting Standards
On January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments—Credit Losses (“ASU 2016-13”) using the modified retrospective transition approach, with the impact upon adoption reflected in opening retained earnings. The comparative prior year information has not been adjusted and continues to be reported under legacy GAAP. The standard significantly changed the impairment model for most financial assets and certain other instruments, including accounts receivable and available-for-sale securities.
For financial assets measured at amortized cost, including our accounts receivable, the standard requires an entity to (1) estimate its lifetime expected credit losses upon recognition of the financial assets and establish an allowance to present the net amount expected to be collected, (2) recognize this allowance and changes in the allowance during subsequent periods through net income and (3) consider relevant information about past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses.
For available-for-sale debt securities, this standard made several targeted amendments to the existing other-than-temporary impairment model, including (1) requiring disclosure of the allowance for credit losses, (2) allowing reversals of the previously recognized credit losses until the entity has the intent to sell, is more-likely-than-not required to sell the securities or the maturity of the securities, (3) limiting impairment to the difference between the amortized cost basis and fair value and (4) not allowing entities to consider the length of time that fair value has been less than amortized cost as a factor in evaluating whether a credit loss exists.
As a result of adoption, the cumulative impact related to accounts receivable expected credit losses to our opening retained earnings at January 1, 2020 was $1.2 million. As of the adoption date, the difference between the amortized cost basis and fair value of the Company’s impaired available-for-sale securities held was not material. Accordingly, upon adoption there was no impact to our opening retained earnings for credit losses related to available-for-sale securities. For additional information on the impact of the adoption and disclosures required by ASU 2016-13, refer to the updates to significant accounting policies section below, Note “3. Investments and Fair Value of Financial Instruments” and Note “4. Balance Sheet Components.”
On January 1, 2020, the Company adopted ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The primary focus of the standard is to improve the effectiveness of the disclosure requirements for fair value measurements. The Company assigns revenuehad no significant changes to the fair value measurement related disclosures due to the adoption of the standard.
Updates to Significant Accounting Policies
As a result of the adoption of the ASU 2016-13, the Company has made the following updates to its significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019.
Significant Accounting Policies Update - Credit Losses
The Company is exposed to credit losses primarily through our accounts receivable from sales of products on credit terms of one year or less. The Company performs ongoing credit evaluations of its customers, does not require collateral, and maintains allowances for potential credit losses on customer accounts. The Company monitors its ongoing credit exposure and concentration through active review of customers balances against contract terms, due dates, geographic area basedrelated risks and current economic conditions impacting our customers. Our activities include timely account reconciliation, dispute resolution and payment confirmation. Refer to “Significant Accounting Policies - Accounts Receivable” for more information on the destinationallowance for credit losses on the Company’s accounts receivables.
The Company is also exposed to which it shipscredit losses through its products.

investments in available-for-sale securities. An investment is impaired if the fair value of the investment is less than its amortized cost basis. The Company reviews each impaired available-for-sale security held in its portfolio to determine whether the decline in fair value below its amortized cost basis is the result of credit losses or other factors. An allowance for credit losses is to be recorded as a charge to net income in an amount equal to the difference between the impaired security’s amortized cost basis and the amount expected to be collected over the lifetime of security, limited by the amount that the fair value is less than its amortized cost basis. Any remaining difference between its

amortized cost basis and fair value is deemed not to be due to expected credit losses and is recorded as a component of accumulated other comprehensive loss.
RecentThe Company’s impairment review considers several factors to determine if an expected credit loss is present including the discounted present value of expected cash flows of the security, the capacity to hold a security or sell a security before recovery of the decline in amortized cost, the credit rating of the security and forecasted and historical factors that affect the value of the security.
See Note “3. Investments and Fair Value of Financial Instruments” for more information.
Significant Accounting GuidancePolicies Update - Accounts Receivable
Recently Adopted Accounting Standards
Accounts receivable are measured at amortized cost less the allowances for credit losses. In July 2015, the Financial Accounting Standards Board (FASB”) issuedaccordance with ASU No. 2015-11, Simplifying the Measurement2016-13, as of Inventory, which requires an entity to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. In January 2017,1, 2020, the Company adoptedmeasures expected credit losses for its accounts receivables utilizing a loss-rate approach. The allowance for expected credit losses assessment requires a degree of estimation and judgement. The expected loss-rate is calculated by utilizing historical credit losses incurred as percentage of the standard onCompany’s historical accounts receivable balances, pooled by customers with similar geographic credit risk characteristics. The loss-rate is adjusted for management’s expectations regarding current conditions and forecasts about future conditions which impact expected credit losses. The Company considers factors such as customers credit risk, geographic related risks and economic conditions that may affect a prospective basis andcustomer’s credit quality classification. Prior to the adoption did not haveof ASU 2016-13, the Company recognized losses when a material impact on its financial position.loss was incurred or deemed probable.

At September 30, 2020, the Company reported $112.8 million of accounts receivable, net of credit losses of $2.1 million. See Note “4. Balance Sheet Components” for more information.
Recently Issued Accounting Standards
In May 2014,December 2019, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which outlines a comprehensive new revenue recognition model designed to depict2019-12, Income Taxes— Simplifying the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchangeAccounting for those goods or services. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with CustomersPrincipal versus Agent Considerations (Reporting Revenue Gross versus Net),which further clarifies the implementation guidance on principal versus agent considerations contained in ASU No. 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with CustomersIdentifying Performance Obligations and Licensing, which further clarifies the implementation guidance relating to identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with CustomersNarrow-Scope improvements and Practical Expedients, which further clarifies the implementation on narrow scope improvements and practical expedients. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606Revenue from Contracts with Customers, which makes minor corrections or minor improvements to the Codification related to ASU No. 2014-09 that are not expected to have a significant effect on the Companys current accounting practice. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments, (“ASU No. 2017-13”) which provides additional clarification and implementation guidance on the previously issued ASU No. 2014-09. These standards will be effective for the Company in the first quarter of 2018 pursuant to ASU No. 2015-14, Revenue from Contracts with Customers-Deferral of the Effective Date,issued by the FASB in August 2015.Income Taxes. The Companystandard intends to adoptsimplify and reduce the new standard on a modified retrospective basis on January 1, 2018. Under this method, the Company will record a cumulative-effect adjustment to the opening balancecost of retained earnings in the initial year of adoption. The timing of revenue recognition based on the guidance related to transfer of control may result in acceleration of revenue recognitionaccounting for some contracts. The Company does not expect the impact of the new standard to be material, but it expands financial statement disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. As we continue our assessment through the remainder of 2017, our preliminary assessment is subject to change.

In February 2016, the FASB issued ASU No. 2016-02, Leases, which amends the existing accounting standards for leases. In September 2017, the FASB issued ASU No. 2017-13 which provides additional clarification and implementation guidance on the previously issued ASU No. 2016-02. Under the new guidance, a lessee will be required to recognize a lease liability and right-of-use asset for all leases with terms in excess of twelve months.income taxes. The new guidance removes certain exceptions for recognizing deferred taxes for foreign investments, the incremental approach to performing intraperiod allocation, and calculating income taxes in interim periods for year to date losses that exceed anticipated full year losses. The standard also modifies the classification criteria andadds guidance to reduce complexity in certain areas, including accounting for sales-type and direct financing leases, and requires additional disclosures to enable usersfranchise taxes that are partially based on income, transactions with a government that result with a step up in the tax basis of financial statements to understand the amount, timing, and uncertainty of cash flows arising from leases. Consistent with current guidance, a lessee’s recognition, measurement, and presentation of expenses and cash flows arising from a lease will continue to depend primarily on its classification. The accounting standard is effective for fiscal years beginning after December 15, 2018, includinggoodwill, enacted changes in tax law during interim periods, within those fiscal years, and must be applied usingallocating taxes to members of a modified retrospective approach. Early adoption is permitted. While the Company is continuing to assess all potential impacts of the standard, it expects that most of its lease commitments will beconsolidated group which are not subject to tax. For public business entities, the updated standard and recognized as lease liabilities and right-of-use assets upon adoption.
In June 2016, the FASB issuedamendments in ASU No. 2016-13, Financial Instruments-Credit Losses. The standard changes how entities will measure credit losses for most financial assets and certain other instruments that2019-12 are not measured at fair value through net income. The Company will recognize an allowance for credit losses on available-for-sale securities rather than deductions in amortized cost. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.2020. Early adoption is permitted for all periods beginning after December 15, 2018.in which financial statements have not yet been issued, including interim periods. The Company is currently evaluating the impact of adopting the new guidance.
In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments in this standard are effective for the Company for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including early adoption in an interim period. The amendments in this standard should be applied prospectively. Under a prospective transition, the Company would apply the amendments at the beginning of the interim period that includes the adoption date. The Company is currently evaluating the impact of adopting the new standard.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, a consensus of the FASB Emerging Issues Task Force. The standard requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling the total beginning and end of period amounts shown on the statement of cash flows. The standard is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company does not expect the adoption of ASU 2016-18 to have a material impact on its consolidated financial statements.
In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation - Scope of Modification Accounting. The standard provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This standard does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The standard is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The guidance will be applied prospectively upon adoption. The Company does not expect the adoption of ASU 2017-09 to have a material impact on its consolidated financial statements, however the impact to share-based compensation expense will depend on the terms specified in any new changes to share-based payment awards subsequent to the adoption.

Non-Marketable Equity Investments
In May 2017, the Company and an unrelated third-party formed a privately-held company, MVI Health Inc. (MVI), with each party holding 50% of the issued and outstanding equity of MVI. The Company accounted for its investment under the equity method and is not required to consolidate MVI under the voting model. As of September 30, 2017, the Company determined that MVI was not a variable interest entity (“VIE”). The Company will reassess in subsequent periods whether MVI becomes a VIE due to changes in facts and circumstances, including changes to the sufficiency of the equity investment at risk, management and governance structure or capital structure. As of September 30, 2017, the carrying value of the non-marketable equity investment was approximately $4.4 million, representing the Company’s contributions to MVI offset by the Company’s share of equity method investee losses. The non-marketable equity method investment is included in other non-current assets on the condensed consolidated balance sheet. During the three and nine months ended September 30, 2017, MVI recorded a net loss of $1.1 million and $1.4 million, respectively, from operating expenses in the same amounts. The Company reflected its 50% share of investee losses for the three and nine months ended September 30, 2017, of $0.5 million and $0.7 million, respectively, as a component of other expense, net, in the condensed consolidated statements of operations and comprehensive income. The Company held no non-marketable equity investments in 2016.

Fair Value of Financial Instruments
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement.
The Company classifies its cash equivalents and marketable investments within Level 1 and Level 2, as it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs.
The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.
Financial instruments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, or historical pricing trends of a security relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. In addition, the Company assesses the inputs and methods used in determining the fair value in order to determine the classification of securities in the fair value hierarchy.

The contingent consideration is classified as a Level 3 measurement forpayment due which fair value is derived from inputs that are unobservable and significant to the overall fair value measurement. The fair value of such milestone payments is estimated using a Monte Carlo simulation model that utilizes key assumptions including forecasted revenueswas paid during the earn-out period and revenue and asset volatilities. The fair valuefirst quarter of the contingent consideration liability will be evaluated each reporting period and changes in its fair value will be included in the Company’s results of operations.

Acquired intangible assets are classified as Level 3 measurements for which fair value is derived from valuations based on inputs that are unobservable and significant to the overall fair value measurement. The Company used the income approach, specifically the discounted cash flow method and the incremental cash flow approach, to derive the fair value of the customer relationships and other intangible assets. Customer relationships are direct relationships with physicians and hospitals performing procedures with the distributed products. Other intangibles consists of non-Penumbra supplier relationships and sub-distributor relationships with third parties used to sell products, both as of the Closing Date. The intangible assets are amortized on a straight-line basis over their assigned estimated useful lives. The acquired intangible assets will not be amortized for tax purposes. As a result, a $2.5 million deferred tax liability was recorded as of September 30, 2017.
The goodwill arising from the Crossmed acquisition is primarily attributed to expected synergies from future growth and assembled workforce. Goodwill will not be deductible for tax purposes.
The amount of Crossmed’s net revenue and net loss included in the Company’s condensed consolidated statements of operations and comprehensive income was $2.7 million and $0.3 million, respectively, for each of the three and nine months ended September 30, 2017

Contingencies
From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. Refer to Note “3. Investments and Fair Value of Financial Instruments,” Note “5. Business Combination”Combinations,” Note “6. Intangible Assets” and Note “6. Goodwill and Intangible Assets”“8. Indebtedness” for more information on contingent liabilities recorded on the condensed consolidated balance sheet.
Indemnification
The Company enters into standard indemnification arrangements in the ordinary course of business. In many such arrangements, the Company agrees to indemnify, hold harmless, and reimburse the indemnified parties for losses suffered or incurred by the indemnified parties in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third-party with respect to the Company’s technology. The Company also agrees to indemnify many purchasersindemnified parties for product defect and similar claims. The term of these indemnification agreements is generally perpetual.

The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with any of these indemnification requirements has been recorded to date.
Litigation
The Company was contacted in 2015 by the attorney for a potential product liability claimant who allegedly suffered injuries as a result of an aneurysm procedure in which the Penumbra Coil 400 was used. On February 19, 2016, a complaint for damages was filed on behalf of this claimant against the Company and the hospital involved in the procedure (Montgomery v. Penumbra, Inc., et al., Case No. 16-2-04050-1 SEA, Superior Court of the State of Washington, King County). The suit alleges liability primarily under the Washington Product Liability Act (“WPLA”) and sought both compensatory and punitive damages without a specific damages claim. Based on the Company’s preliminary motion, the punitive damages claim was dismissed in May 2016, along with several of the other causes of actions subsumed by the WPLA. In recent submissions, plaintiffs claimed economic and non-economic damages in an amount substantially in excess of the Company’s insurance coverage. The parties reached a preliminary agreement to settle this matter on confidential terms at a mediation held November 1, 2017. The settlement is subject to finalization and does not have a material financial impact on the Company. If for any reason the settlement is not finalized, the case would continue in the discovery phase, with a trial currently set for April 2018. The Company would continue to vigorously defend the litigation, as the Company believes there are substantial questions regarding causation, liability and damages. If the case proceeds to trial, the results of any jury trial and the damages that a jury might award are inherently uncertain.
From time to time, the Company is subject to other claims and assessments in the ordinary course of business. The Company is not currently a party to any such litigation matter that, individually or in the aggregate, is expected to have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

As such, a partial valuation allowance was recorded against the Company’s domestic DTAs as of September 30, 2017 in the amount of $18.6 million, which was approximately the same amount as the stock-based compensation excess tax benefits created during the nine months ended September 30, 2017.

The Company will continue to closely monitor the need for an additional valuation allowance against its existing domestic DTAs and any additional DTAs that are generated in each subsequent reporting period, which can be impacted by actual operating results compared to the Company’s forecast.
Consistent with prior periods, the Company maintained a full valuation allowance against its California and Canada DTAs as of September 30, 2017.

14. Revenues
Revenue Recognition
Revenue is recognized in an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services. All revenue recognized in the condensed consolidated statements of operations is considered to be revenue from contracts with customers.
The following table presents the Company’s revenues disaggregated by geography, based on the destination to which the Company ships its products, for the three and nine months ended September 30, 2020 and 2019 (in thousands):

Performance Obligations
Delivery of products - The Company’s contracts with customers typically contain a single performance obligation, delivery of Penumbra products. Satisfaction of that performance obligation occurs when control of the promised goods transfers to the customer, which is generally upon shipment for non-consignment sale agreements and upon utilization for consignment sale agreements.

(unaudited)
Payment terms - The Company’s payment terms vary by the type and location of our customer. The timing between fulfillment of performance obligations and when payment is due is not significant and does not give rise to financing transactions. The Company did not have any contracts with significant financing components as of September 30, 2020.
Product returns - The Company may allow customers to return products purchased at the Company’s discretion. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its own historic sales information, trends, industry data, and other relevant data points.
Warranties - The Company offers its standard warranty to all customers and it is not available for sale on a standalone basis. The Company’s standard warranty represents its guarantee that its products function as intended, are free from defects, and comply with agreed-upon specifications and quality standards. This assurance does not constitute a service and is not a separate performance obligation.
Transaction Price
Revenue is recorded at the net sales price, which includes estimates of variable consideration such as product returns utilizing historical return rates, rebates, discounts, and other adjustments to net revenue. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price. When determining if variable consideration should be constrained, management considers whether there are factors that could result in a significant reversal of revenue and the likelihood of a potential reversal. Variable consideration is included in revenue only to the extent that it is probable that a significant reversal of the revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. These estimates are reassessed each reporting period as required. During the three and nine months ended September 30, 2020, the Company made no material changes in estimates for variable consideration. When the Company performs shipping and handling activities after control of goods is transferred to the customer, they are considered as fulfillment activities, and costs are accrued for when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

Overview
Penumbra (“we,” “our,” “us,” “Penumbra,” and the “Company”) is a global healthcare company focused on interventionalinnovative therapies. We design, develop, manufacture and market innovative devicesnovel products and have a broad portfolio of products that addresses challenging medical conditions andin markets with significant clinical needs across two major markets, neuro and peripheral vascular. The conditions that our products address include, among others, ischemic stroke, hemorrhagic stroke and various peripheral vascular conditions that can be treated through thrombectomy and embolization procedures.
unmet need. Our team focuses on developing, manufacturing and marketing novel products for use by specialist physicians including interventional neuroradiologists, neurosurgeons, interventional neurologists, interventional radiologists and vascular surgeons. We design our products to provide these specialist physicians with a meanshealthcare providers to drive improved clinical outcomes, and weoutcomes. We believe that the cost-effectiveness of our products is attractive to our hospital customers.
Since our founding in 2004, we have invested heavily in our product development capabilities in our two keymajor markets: neuro and peripheral vascular. We launched our firsthave successfully developed, obtained regulatory clearance or approval for, and introduced products into the neurovascular product inmarket since 2007, our first peripheral vascular product inmarket since 2013 and neurosurgical market since 2014, respectively. We continue to expand our first neurosurgicalportfolio of product in 2014. offerings, while developing and iterating on our currently available products.
We expect to continue to develop and build our portfolio of products, based onincluding our thrombectomy, embolization and access technologies. Generally, when we introduce a next generation product or a new product designed to replace a current product, sales of the earlier generation product or the product replaced decline. Our research and development activities are centered around the development of new products and clinical activities designed to support our regulatory submissions and demonstrate the effectiveness of our products.
To address the challenging and significant clinical needs of our two key markets, we developed products that fall into the following broad product offering families:
Our neuro products fall into fourfive broad product families:
Neuro thrombectomy - the Penumbra System, consisting of reperfusion catheters and separators, aspiration tubing and aspiration pump,including Penumbra JET, ACE and the 3D revascularization deviceRevascularization Device, Penumbra ENGINE and other components and accessories
Neuro embolization - Penumbra SMART COIL, Penumbra Coil 400, POD400 and Penumbra SMART COILPAC400

and the POD System (POD and POD Packing Coil)
We sell our products to hospitals and other healthcare providers primarily through our direct sales organization in the United States, most of Europe, Canada and Australia, as well as through distributors in select international markets. In the nine months ended September 30, 20172020 and 2016, 33.7%2019, 28.0% and 33.0%35.6% of our revenue, respectively, was generated from customers located outside of the United States. Our sales outside of the United States are denominated principally in the euro and Japanese yen, with some sales being denominated in other currencies. As a result, we have foreign exchange exposure but do not currently engage in hedging.
We generated revenue of $237.7$393.5 million and $190.2$402.1 million for the nine months ended September 30, 20172020 and 2016,2019, respectively, an increasea decrease of 25.0%.$8.6 million. We generated an operating loss of $2.7$37.2 million and $0.2operating income of $36.9 million for the nine months ended September 30, 20172020 and 2016,2019, respectively.
COVID-19 Pandemic
In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the U.S. and the world. In response, governments have issued orders restricting certain activities, and while our business falls within the category of healthcare operations, which are essential businesses currently permitted to continue operating during the COVID-19 outbreak, we have experienced, and expect to continue to experience, disruptions to our operations as a result of the pandemic. For example, hospital resources have been diverted to fight the pandemic, and many government agencies in conjunction with healthcare systems have recommended the deferral of elective and semi-elective medical procedures during the outbreak. Some of Penumbra’s medical devices are used in certain procedures that the United States Centers for Medicare & Medicaid Services (“CMS”) has indicated are “high-acuity” procedures that should not be postponed during the outbreak in its March 18, 2020 recommendations, while other Penumbra devices are used in elective procedures that physicians may consider postponing. Many of the procedures in which our vascular products are used are elective in nature, whereas procedures in which our neuro products are used, such as stroke, tend to be more emergent in nature.
The impact of COVID-19 on our business remains fluid, and we continue to actively monitor the dynamic situation. We will continue to undertake the following specific actions and strategic priorities to navigate the pandemic:
We have made changes to how we manufacture, inspect and ship our products to prioritize the health and safety of our employees and to operate under the protocols mandated by our local and state governments. While we are committed to continue meeting demand for our essential devices, we have implemented social distancing and other measures to protect the health and safety of our employees, which have reduced, and may continue to reduce, our manufacturing capacity.
In order to strengthen our liquidity position, we issued and sold an aggregate of 865,963 shares of our common stock at a public offering price of $166.00 per share, less the underwriters’ discounts and commissions, pursuant to an underwritten public offering in June 2020. We received approximately $134.8 million in net cash proceeds from the offering after deducting underwriting discounts and commissions of $8.6 million and other offering expenses of $0.4 million.
We further strengthened our liquidity position by entering into a Credit Agreement (the “Credit Agreement”) on April 24, 2020, with JPMorgan Chase Bank, N.A., as administrative agent and lender, and Bank of America, N.A. and Citibank, N.A. as lenders. The Credit Agreement is secured and provides for up to $100 million in available revolving borrowing capacity with an option, subject to certain conditions, for us to increase the aggregate borrowing capacity to up to $150 million, and matures on April 23, 2021. This revolving line of credit provides access to capital beyond the $268.7 million in cash, cash equivalents and marketable investments on our balance sheet as of September 30, 2020, and we believe this will allow us to both navigate the current environment and emerge in a strong liquidity position after the pandemic. As of September 30, 2020, the Company was not in compliance with the requirement in the Credit Agreement to maintain a minimum fixed charge coverage ratio. The Company subsequently obtained a waiver of such non-compliance from the lenders under the Credit Agreement. As of September 30, 2020, there were no borrowings outstanding under the Credit Agreement.
We will continue to prioritize investments in our production capacity and flexibility, commercial channels, preparation for new product launches, and new product developments to help patients.
While we have seen positive trends in certain areas of our business beginning in May, we remain mindful of the negative impacts on business trends we experienced in April due to the COVID-19 outbreak. The general impact of COVID-19 on our business has been negative and we are unable to reliably predict the full impact that COVID-19 will have on our business due to

numerous uncertainties, including the severity and duration of the outbreak, the global resurgences of cases, additional actions that may be taken by governmental authorities in response to the outbreak, the impact of the outbreak on the business of our customers, distributors and suppliers, other businesses and worldwide economies in general, our ability to have access to our customers to provide training and case support, and other factors identified in Part II, Item 1A “Risk Factors” in this Quarterly Report on Form 10-Q. We will continue to evaluate the nature and extent of the impact of COVID-19 on our business, consolidated results of operations, and financial condition.
Factors Affecting Our Performance
There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include: 
The COVID-19 outbreak and measures taken in response thereto, which have negatively affected, and we expect will continue to negatively affect, our revenues and results of operations. Due to these impacts and measures, we may experience significant and unpredictable fluctuations in demand for certain of our products as hospital customers re-prioritize the treatment of patients and distributors adjust their operations to support the current demand level.
The rate at which we grow our salesforce and the speed at which newly hired salespeople become fully effective can impact our revenue growth or our costs incurred in anticipation of such growth.
Our industry is intensely competitive and, in particular, we compete with a number of large, well-capitalized companies. We must continue to successfully compete in light of our competitors’ existing and future products and their resources to successfully market to the specialist physicians who use our products.
We must continue to successfully introduce new products that gain acceptance with specialist physicians and successfully transition from existing products to new products, ensuring adequate supply while avoiding excess inventory of older products and resulting inventory write-downs or write-offs.supply. In addition, as we introduce new products and expand our production capacity, we generally hire and trainanticipate additional personnel will be hired and trained to build our inventory of components and finished goods in advance of sales, which may cause quarterly fluctuations in our operating results and financial condition.
Publications of clinical results by us, our competitors and other third parties can have a significant influence on whether, and the degree to which, our products are used by specialist physicians and the procedures and treatments those physicians choose to administer for a given condition.
The specialist physicians who use our products may not perform procedures during certain times of the year, such as those periods when they are at major medical conferences or are away from their practices for other reasons, the timing of which occurs irregularly during the year and from year to year.
Most of our sales outside of the United States are denominated in the local currency of the country in which we sell our products. As a result, our revenue from international sales can be significantly impacted by fluctuations in foreign currency exchange rates.
The availability and levels of reimbursement within the relevant healthcare payment system for healthcare providers for procedures in which our products are used.
In addition, we have experienced and expect to continue to experience meaningful variability in our quarterly revenue, gross profit and gross margin percentage as a result of a number of factors, including, but not limited to: the impact of COVID-19, the number of available selling days, which can be impacted by holidays; the mix of products sold; the geographic mix of where products are sold; the demand for our products and the products of our competitors; the timing of or failure to obtain regulatory approvals or clearances for products; increased competition; the timing of customer orders; inventory write-offs and write-downs;due to obsolescence; costs, benefits and timing of new product introductions; costs, benefits and timing of the acquisition and integration of businesses and product lines we may acquire; the availability and cost of components and raw materials; and fluctuations in foreign currency exchange rates. We may experience quarters in which we have significant revenue growth sequentially followed by quarters of moderate or no revenue growth. Additionally, we may experience quarters in which operating expenses, in particular research and development expenses, fluctuate depending on the stage and timing of product development.

Components of Results of Operations
Revenue.We sell our products directly to hospitals and other healthcare providers and through distributors for use in procedures performed by specialist physicians to treat patients in two key markets: neuro and peripheral vascular disease. We sell our products through purchase orders, and we do not have long term purchase commitments from our customers. We typically recognize revenueRevenue from product sales is recognized either on the date of shipment or the date of receipt by the customer, but is deferred for certain transactions when products are delivered to our hospital customers or distributors. However, withcontrol has not yet transferred. With respect to products that we consign to hospitals, which primarily consist of coils, we recognize revenue at the time hospitals utilize products in a procedure. Revenue also includes shipping and handling costs that we charge to customers.
Cost of Revenue.Cost of revenue consists primarily of the cost of raw materials and components, personnel costs, including stock-based compensation, inbound freight charges, receiving costs, inspection and testing costs, warehousing costs, royalty expense, shipping and handling costs, and other labor and overhead costs incurred in the manufacturing of products. In addition, we record write-downs or write-offs of inventory in the event that a portion of our inventory becomes excess or obsolete.
We manufacture substantially all of our products in our manufacturing facility at our campusfacilities in Alameda and Roseville, California.
Operating Expenses

Research and Development (R&D)(“R&D”). R&D expenses primarily consist of product development, clinical and regulatory expenses, materials, depreciation and other costs associated with the development of our products. R&D expenses also include salaries, benefits and other related costs, including stock-based compensation, for personnel and consultants. We generally expense R&D costs as they are incurred.incurred, with the exception of certain costs incurred for the development of computer software for internal use related to our REAL Immersive System offerings. We capitalize certain costs when it is determined that it is probable that the project will be completed and the software will be used to perform the function intended, and the preliminary project stage is completed. Capitalized internal use software development costs are included in property and equipment, net within the condensed consolidated balance sheets.
We expect our R&D expenses to continue to increase as we innovate and develop new products, add personnel, engage in ongoing clinical research and expand our information technologies.
Sales, General and Administrative (SG&A)(“SG&A”).SG&A expenses primarily consist of salaries, benefits and other related costs, including stock-based compensation, for personnel and consultants engaged in sales, marketing, finance, legal, compliance, administrative, facilities and information technology and human resource activities. Our SG&A expenses also include marketing trials, medical education, training, commissions, generally based on a percentage of sales, to direct sales representatives, amortization of acquired intangible assets and acquisition-related costs.costs.
We expect our SG&A expenses to continue to increase as we expand our marketing programs, information technologies, operations and salesforce.(Benefit from) Provision For Income Taxes
Income Tax Expense. We are taxed at the rates applicable within each jurisdiction in which we operate. The composite income tax rate, tax provisions, DTAsdeferred tax assets (“DTAs”) and deferred tax liabilities will vary according to the jurisdiction in which profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require us to exercise judgment in determining our income tax provision, our DTAsdeferred tax assets and deferred tax liabilities and the potential valuation allowance recorded against our net deferred tax assets.DTAs. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not that the future realization of all or some of the DTAs will not be achieved.

Our2019. The overall growth in our revenue growth resulted fromis primarily due to an increase in products sales within our vascular business as a result of sales of new products and further market penetration of our existing products, andpartially offset by a decline in sales of new products or products with new indications. Increased sales within our neuro business.
Revenue from our neuro products decreased $7.3 million, or 8.8%, to $75.9 million in the three months ended September 30, 2020, from $83.2 million in the three months ended September 30, 2019. This decrease was primarily attributable to decreased sales of our neuro thrombectomy products which globally declined by 23.2% in the three months ended September 30, 2020. This decrease was primarily attributable to decreased sales in Japan as a result of reimbursement changes, on-going discussions with our distributor partner, and peripheral vascular businesses accounted for approximately two-thirdsthe paused launch of our new stroke product in that market. This decline was partially offset by an increase in sales of our neuro access and one-third of the revenue increase,neuro embolization products, which globally increased by 35.0% and 9.7%, respectively in the three months ended September 30, 2017.
Revenue from our neuro products increased $11.1 million, or 23.4%, to $58.7 million in the three months ended September 30, 2017, from $47.5 million in the three months ended September 30, 2016. This was primarily attributable to increased sales of our Penumbra System and neuro access products, which accounted for approximately 75% and slightly less than 20% of the neuro revenue increase, respectively. Our neuro product sales experienced strong momentum2020, due to further market penetration and growth in the market for endovascular treatment of stroke. The overall market growth has led to increases in the number of procedures performed by specialist physicians using our products. Further, there was greater demand for our neuro access products, which can fluctuate from period to period due to the number of procedures performed. Prices for our neuro products remained substantially unchanged during the period.

The effective tax rate was 41.6% for nine months ended September 30, 2020, compared to 1.8% for the nine months ended September 30, 2016 includes the retroactive adoption of ASU 2016-09. The2019. Our change in effective tax rate was primarily attributable to the exclusion oflarge tax benefits attributable to our US jurisdiction due toover worldwide losses for the partial valuation allowance recorded against our domestic DTAs as ofnine months ended September 30, 2017 but including2020, when compared to small tax benefits attributable to our domestic DTAs as ofexpenses over worldwide profits for the nine months ended September 30, 2016, and the tax impact from recognizing the deferred tax assets associated with intra-entity asset transfers.2019.
Prospectively, our effective tax rate will likely be driven by (1) exclusion of thepermanent differences in taxable income for tax benefits attributable to the U.S. jurisdiction due to valuation allowances recorded against domestic DTAs generated in subsequent periods,and financial reporting purposes, (2) tax expense associated withattributable to our foreign operationsworldwide profit or tax benefit attributable to our worldwide losses, and (3) discrete tax impact associatedadjustments such as excess tax benefits related to stock-based compensation. Our income tax provision is subject to volatility as the amount of excess tax benefits can fluctuate from period to period based on the price of our stock, the volume of share-based grants settled or vested, and the fair value assigned to equity awards under U.S. GAAP. In addition, changes in tax law or our interpretation thereof, and changes to our valuation allowance could result with intra-entity asset transfers.fluctuations in our effective tax rate.
Liquidity and Capital Resources
As of September 30, 2017,2020, we had $320.7$482.1 million in working capital, which included $65.6$80.1 million in cash and cash equivalents and $153.2$188.6 million in marketable investments. As of September 30, 2017,2020, we held approximately 24.9%22.9% of our cash and cash equivalents in foreign banks.entities.
In March 2017,June 2020, we issued and sold an aggregate of 1,495,000865,963 shares of our common stock at a public offering price of $76.00$166.00 per share, less the underwriters’ discounts and commissions, pursuant to an underwritten public offering. We received approximately $106.3$134.8 million in net cash proceeds from the offering after deducting underwriting discounts and commissions of $6.8$8.6 million and other offering expenses of $0.5$0.4 million. We intend to use the net proceeds from thisthe offering for general corporate purposes, including working capital, continued development of our products, including research and development and clinical trials, potential acquisitions and other business opportunities. Pending the use of the net proceeds from thisthe offering, we are investing the net proceeds in investment grade, interest bearing securities.

In addition to our existing cash and cash equivalents and marketable investment balances, our principal source of liquidity is our accounts receivable. In order to further strengthen our liquidity position and financial flexibility during the COVID-19 pandemic, on April 24, 2020 we entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and lender, and Bank of America, N.A. and Citibank, N.A. as lenders. The Credit Agreement is secured and provides for up to $100 million in available revolving borrowing capacity with an option, subject to certain conditions, for the Company to increase the aggregate borrowing capacity to up to $150 million, and matures on April 23, 2021. As of September 30, 2020, the Company was not in compliance with the requirement in the Credit Agreement to maintain a minimum fixed charge coverage ratio. The Company subsequently obtained a waiver of such non-compliance from the lenders under the Credit Agreement. As of September 30, 2020, there were no borrowings outstanding under the Credit Agreement. See Note “8. Indebtedness” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for more information.
We believe theseour sources of liquidity will be sufficient to meet our liquidity requirements for at least the next 12 months. Our principal liquidity requirements are to fund our operations, includingexpand manufacturing operations which includes, but is not limited to, maintaining sufficient levels of inventory to meet the anticipated demand of our customers, fund research and development activities and fund our capital expenditures. We may also lease or purchase additional facilities to facilitate our growth. We expect to continue to make investments as we launch new products, expand our manufacturing operations and IT infrastructures and further expand into international

markets. We may, however, require or elect to secure additional financing as we continue to execute our business strategy. If we require or elect to raise additional funds, we may do so through equity or debt financing, which may not be available on favorable terms, could result in dilution to our stockholders, could result in changes to our capital structure, and could require us to agree to covenants that limit our operating flexibility.
While we have strengthened our liquidity position, as a result of the COVID-19 pandemic, we cannot reliably estimate the extent to which the COVID-19 pandemic may impact our cash flow from operations in the fourth quarter and beyond.

Critical Accounting Policies and Estimates
We have prepared our financial statements in accordance with U.S. GAAP. Our preparation of these financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosures at the date of the financial statements, as well as revenue and expenses recorded during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from these estimates under different assumptions or conditions.
As a result of transactions completed in the third quarter of 2017, the Company has included the following additional critical accounting policies and estimates:
Goodwill
Goodwill represents the excess of the purchase price of an acquired business or assets over the fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but is tested for impairment at least annually, or more frequently if events or circumstances indicate the carrying value may no longer be recoverable and that an impairment loss may have occurred. We will continue to operate as one segment, which is considered to be the sole reporting unit, and therefore goodwill is tested for impairment at the consolidated level.

Valuation of Intangible Assets
The fair value of identifiable intangible assets acquired in a business combination or through licensing arrangements is determined based on detailed valuations that use information and assumptions provided by management, which consider

management’s best estimates of inputs and assumptions that a market participant would use. These estimates include the amount and timing of projected milestone-based payments on sales that are considered probable and estimable, the amount and timing of projected future cash flows of each acquired intangible asset, the discount rate used to discount those cash flows to present value, the assessment of the asset’s life cycle, and the consideration of legal, technical, regulatory, economic, and competitive risks.
Finite-lived intangible assets are amortized using the straight-line method over the estimated economic useful lives of the assets, which is the period during which expected cash flows support the fair value of such intangible assets. We will review finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such an event occurs, management will determine whether there has been impairment by comparing the anticipated undiscounted future net cash flows to the related asset group’s carrying value. If an asset is considered impaired, the asset will be written down to the determined fair value based on discounted cash flows. We also periodically review the useful lives assigned to our intangible assets to ensure that our initial estimates do not exceed any revised estimated periods from which we expect to realize cash flows from the underlying intangible asset. If a change were to occur in any of the above-mentioned factors or estimates, the likelihood of a material change in our reported results would increase.
In addition, the fair value of indefinite-lived intangible assets will be tested for impairment at least annually, or more frequently if events or circumstances indicate their value may no longer be recoverable and that an impairment loss may have occurred.
Valuation of Contingent Consideration Liabilities
Certain agreements the Company enters into, including business combinations and licensing agreements, involve the potential payment of future consideration that is contingent upon certain performance and revenue milestones being achieved. Contingent consideration related to business combinations is recorded at the acquisition date at fair value and is remeasured each reporting period using Level 3 inputs with the change in fair value is recognized within sales, general and administrative expense in the consolidated statements of operations and comprehensive income. Contingent consideration is recorded at the acquisition date at fair value and is remeasured each reporting period using Level 3 inputs. The fair value may be determined using a single approach or a combination or approaches. These include an income approach based on various revenue and cost assumptions and applying a probability-weighted average to each outcome and/or a Monte-Carlo valuation model that simulates outcomes based on management estimates. Significant increases or decreases in the fair value of our contingent consideration liabilities can result from changes in discount periods and rates, as well as changes in the timing and amount of projected revenue or estimates in the timing or likelihood of achieving revenue-based milestones.
There have been no other material changes to our critical accounting policies from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2016.2019.
Recently Issued Accounting Standards

Summary of Significant Accounting Policies” to our condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
We are exposed to various market risks, which may result in potential losses arising from adverse changes in market rates, such as interest rates and foreign exchange rates. We do not enter into derivatives or other financial instruments for trading or speculative purposes and do not believe we are exposed to material market risk with respect to our cash and cash equivalents and/or our marketable investments.
Interest Rate Risk. We had cash and cash equivalents of $65.6$80.1 million as of September 30, 2017,2020, which consisted of funds held in general checking and savings accounts. In addition, we had marketable investments of $153.2$188.6 million, which consisted primarily of commercial paper, corporate bonds, non-U.S. government debt securities, U.S. agency and government sponsored securities, and U.S. states and municipalities and U.S. Treasury.municipalities. Our investment policy is focused on the preservation of capital and supporting our liquidity needs. Under the policy, we invest in highly rated securities, while limiting the amount of credit exposure to any one issuer other than the U.S. government. We do not invest in financial instruments for trading or speculative purposes, nor do we use leveraged financial instruments. We utilize external investment managers who adhere to the guidelines of our investment policy. The revolving loans under our Credit Agreement bear interest at: 1) the adjusted LIBO rate or adjusted EURIBO rate, as applicable, plus an applicable rate, for euro currency revolving borrowing; or 2) an alternate base rate plus an applicable rate, for revolving borrowing in U.S. Dollars. As of September 30, 2020, there were no borrowings outstanding under the Credit Agreement. A hypothetical 100 basis point change in interest rates would not have a material impact on the value of our cash and cash equivalents or marketable investments.
Foreign Exchange Risk Management. We operate in countries other than the United States, and, therefore, we are exposed to foreign currency risks. We bill most sales outside of the United States in local currencies, primarily euro and Japanese yen, with some sales being denominated in other currencies. We expect that the percentage of our sales denominated in foreign currencies may increase in the foreseeable future as we continue to expand into international markets. When sales or expenses are not denominated in U.S. dollars, a fluctuation in exchange rates could affect our net income. We do not believe our net income attributable to Penumbra, Inc. would be materially impacted by an immediate 10% adverse change in foreign exchange rates. We do not currently hedge our exposure to foreign currency exchange rate fluctuations; however, we may choose to hedge our exposure in the future.
We do not believe that inflation and changes in prices had a significant impact on our results of operations as of and for any periods presented on our condensed consolidated financial statements.the period ended September 30, 2020.

ITEM 4. CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
An evaluation as of September 30, 20172020 was carried out under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of our “disclosure controls and procedures,” which are defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange(the “Exchange Act”), as controls and other procedures of a company that are designed to ensure that the information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective at September 30, 2017.2020.
Changes in Internal Control Over Financial Reporting
There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarterly period ended September 30, 20172020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Limitations on the Effectiveness of Controls
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our principal executive officer and principal financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were effective to provide reasonable assurance that the objectives of our disclosure control system were met.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.
We were contactedFor information with respect to Legal Proceedings, see Note “9. Commitments and Contingencies” to our condensed consolidated financial statements in 2015 by the attorney for a potential product liability claimant who allegedly suffered injuries as a result of an aneurysm procedure in which the Penumbra Coil 400 was used. On February 19, 2016, a complaint for damages was filed on behalfPart I, Item 1 of this claimant against the Company and the hospital involved in the procedure (Montgomery v. Penumbra, Inc., et al., Case No. 16-2-04050-1 SEA, Superior Court of the State of Washington, King County). The suit alleges liability primarily under the Washington Product Liability Act (“WPLA”) and sought both compensatory and punitive damages without a specific damages claim. BasedQuarterly Report on the Company’s preliminary motion, the punitive damages claim was dismissed in May 2016, along with several of the other causes of actions subsumed by the WPLA. In recent submissions, plaintiffs claimed economic and non-economic damages in an amount substantially in excess of our insurance coverage. The parties reached a preliminary agreement to settle this matter on confidential terms at a mediation held November 1, 2017. The settlement is subject to finalization and does not have a material financial impact on the Company. If for any reason the settlement is not finalized, the case would continue in the discovery phase, with a trial currently set for April 2018. We would continue to vigorously defend the litigation, as we believe there are substantial questions regarding causation, liability and damages. If the case proceeds to trial, the results of any jury trial and the damages that a jury might award are inherently uncertain.Form 10-Q.
From time to time, we are subject to other claims and assessments in the ordinary course of business. We are not currently a party to any such litigation matter that, individually or in the aggregate, is expected to have a material adverse effect on our business, financial condition, results of operations or cash flows.

ITEM 1A. RISK FACTORS.
There have been no material changes to our risk factors reported in, or new factors identified since the filing of, our Annual Report on Form 10-K for the year ended December 31, 2016,2019, which was filed with the SEC on February 28, 2017.26, 2020, except as set forth below.

The ongoing effects of the COVID-19 pandemic could adversely affect our business, financial condition, results of operations, or cash flows.
In December 2019, a strain of coronavirus, known as COVID-19, surfaced in Wuhan, China and resulted in an outbreak throughout the world. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. Governments, public institutions, and other organizations in countries and localities throughout the world have taken and are continuing to take certain emergency measures to combat the spread of COVID-19, including implementation of restrictions on travel and orders that restrict the operations of institutions such as schools and businesses. While the full impact of the COVID-19 outbreak and government response is not yet known, we have experienced negative impacts from this pandemic and it could materially harm our business, results of operations and financial condition in the future.
For example, on March 18, 2020, the United States Centers for Medicare & Medicaid Services released guidance for U.S. healthcare providers recommending the delay of elective surgeries and non-essential medical, surgical, and dental procedures in order to preserve personal protective equipment, beds, and ventilators for use in combating COVID-19. This guidance and similar guidance from other public health authorities resulted in the deferral of procedures in which our products are used, which thereby reduced demand for our products in the relevant periods. Any similar guidance in the future could also further reduce demand for our products in future periods. Furthermore, once the COVID-19 pandemic subsides there may be constraints in the capacities and financial resources of hospitals and other healthcare providers to perform procedures that had been deferred due to COVID-19, which could have an adverse effect on demand for our products following the end of the pandemic. Many hospitals have also implemented restrictions on vendor access, potentially limiting our ability to provide product and case support.
In addition, due to domestic and international governmental orders restricting certain activities in response to COVID-19, including in Alameda, California, where our corporate headquarters and many of our operations, including our principal manufacturing facility, are located, we continue to experience certain disruptions in our business, including changes to our on-site operations to reduce manufacturing capacity and implement social distancing, reductions in our suppliers’ ability to source, maintain inventory and ship raw materials in alignment with our demands, work stoppages, slowdowns and delays, including having most of our employees working outside of our offices, travel restrictions, reduced access to our customers for product training and case support, and cancellation of events, delays in product development efforts and related clinical trials and regulatory clearances and approvals, and other negative impacts on our capacity to manufacture, our suppliers’ capacity to source and ship raw materials and our distributors’ ability to sell and support the use of our products.
The COVID-19 pandemic has also caused significant uncertainty and volatility in global financial markets and the trading prices for the common stock of medical device companies, including Penumbra. Due to such volatility, we may not be able to raise additional capital, if needed, on favorable terms, or at all. Further adverse economic events resulting from the COVID-19 pandemic, including a prolonged recession, depression or other sustained economic downturn, could materially and adversely affect our business, access to capital markets and the value of our common stock.
The ultimate impact of the COVID-19 pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential impacts on our business, healthcare systems, the medical device industry or the global economy as a whole. However, these effects could adversely impact our business, financial condition, results of operations, or cash flows.
