Forward-Looking Statements
The following discussion and analysis of the financial condition and results of
our operations should be read in conjunction with the consolidated financial
statements and related notes included elsewhere in this report. This discussion
contains forward-looking statements that involve risks and uncertainties. Our
actual results could differ materially from those discussed below. Factors that
could cause or contribute to such differences include, but are not limited to,
those identified below, and those discussed in the section titled "Risk Factors"
included elsewhere in this report.
Overview
We are a provider of radio-frequency, or RF, high-performance analog, and
mixed-signal communications systems-on-chip solutions for the connected home,
wired and wireless infrastructure, and industrial and multi-market applications.
We are a fabless integrated circuit design company whose products integrate all
or substantial portions of a broadband communication system. In most cases,
these products are designed on a single silicon-die, using standard digital CMOS
processes and conventional packaging technologies. We believe this enables our
solutions to achieve superior power, performance, and cost advantages relative
to our industry competition. Our customers include electronics distributors,
module makers, original equipment manufacturers (OEMs), and original design
manufacturers (ODMs), who incorporate our products in a wide range of electronic
devices. Examples of such end market electronic devices incorporating our
products include cable DOCSIS broadband modems and gateways; wireline
connectivity devices for in-home networking applications; RF transceivers and
modems for wireless carrier access and backhaul infrastructure; fiber-optic
modules for data center, metro, and long-haul transport networks; video set-top
boxes and gateways; hybrid analog and digital televisions, direct broadcast
satellite outdoor and indoor units; and power management and interface products
used in these and a range of other markets.

We combine our high-performance RF and mixed-signal semiconductor design skills with our expertise in digital communications systems, software, high-performance analog, and embedded systems to provide highly integrated semiconductor devices and platform-level solutions that are manufactured using a range of semiconductor manufacturing processes, including low-cost complementary metal oxide semiconductor, or CMOS, process technology, Silicon Germanium, Gallium Arsenide, BiCMOS and Indium Phosphide process technologies. Our ability to design analog and mixed-signal circuits in CMOS allows us to efficiently combine analog and digital signal processing functionality in the same integrated circuit. As a result, our solutions have high levels of functional integration and performance, small silicon die size, and low power consumption. Moreover, we are uniquely positioned to offer customers a combination of proprietary CMOS-based radio system architectures that provide the benefits of superior RF system performance, along with high-performance analog interface and power management solutions that enable shorter design cycles, significant design flexibility, and low system cost across a wide range of broadband communications, wired and wireless infrastructure, and industrial and multi-market applications. In fiscal 2019, our net revenue was derived primarily from sales of RF receivers and RF receiver systems-on-chip and connectivity solutions into broadband operator voice and data modems and gateways and connectivity adapters, global analog and digital RF receiver products for analog and digital pay-TV applications, radio and modem solutions into wireless carrier access and backhaul infrastructure platforms, high-speed optical interconnect solutions sold into optical modules for data-center, metro and long-haul networks, and high-performance interface and power management solutions into a broad range of communications, industrial, automotive and multi-market applications. Our ability to achieve revenue growth in the future will depend, among other factors, on our ability to further penetrate existing markets; our ability to expand our target addressable markets by developing new and innovative products; changes in government trade policies; and our ability to obtain design

wins with device manufacturers, in particular manufacturers of set-top boxes,
data modems, and gateways for the broadband service provider and Pay-TV
industries, manufacturers selling into the smartphone market, storage networking
market, cable infrastructure market, industrial and automotive markets, and
optical module and telecommunications infrastructure markets.
Products shipped to Asia accounted for 84%, 81% and 89% of net revenue during
the years ended December 31, 2019, 2018 and 2017, respectively, including 60%,
63% and 71%, respectively, from products shipped to China. Although a large
percentage of our products is shipped to Asia, we believe that a significant
number of the systems designed by these customers and incorporating our
semiconductor products are then sold outside Asia. For example, revenue
generated from sales of our cable modem products during the years ended
December 31, 2019, 2018 and 2017 related principally to sales to Asian ODMs and
contract manufacturers delivering products into European and North American
markets. To date, all of our sales have been denominated in United States
dollars.
A significant portion of our net revenue has historically been generated by a
limited number of customers. Sales to customers comprise both direct sales to
customers and indirect sales through distributors. In the year ended December
31, 2019, one of our direct customers, CommScope, accounted for 14% of our net
revenue, and our ten largest customers collectively accounted for 63% of our net
revenue, of which distributor customers comprised 38% of our net revenue. In the
year ended December 31, 2018, Commscope accounted for 18% of our net revenue,
and our ten largest customers collectively accounted for 61% of our net revenue,
of which distributor customers comprised 29% of our net revenue. In the year
ended December 31, 2017, Commscope accounted for 25% of our net revenue, and our
ten largest customers collectively accounted for 58% of our net revenue, of
which distributor customers comprised 9% of our net revenue. For certain
customers, we sell multiple products into disparate end user applications such
as cable modems, satellite set-top boxes and broadband gateways.
Our business depends on winning competitive bid selection processes, known as
design wins, to develop semiconductors for use in our customers' products. These
selection processes are typically lengthy, and as a result, our sales cycles
will vary based on the specific market served, whether the design win is with an
existing or a new customer and whether our product being designed in our
customer's device is a first generation or subsequent generation product. Our
customers' products can be complex and, if our engagement results in a design
win, can require significant time to define, design and result in volume
production. Because the sales cycle for our products is long, we can incur
significant design and development expenditures in circumstances where we do not
ultimately recognize any revenue. We do not have any long-term purchase
commitments with any of our customers, all of whom purchase our products on a
purchase order basis. Once one of our products is incorporated into a customer's
design, however, we believe that our product is likely to remain a component of
the customer's product for its life cycle because of the time and expense
associated with redesigning the product or substituting an alternative chip.
Product life cycles in our target markets will vary by application. For example,
in the cable operator modem and gateway sectors, a design-in can have a product
life cycle of 24 to 48 months. In the industrial and wired and wireless
infrastructure markets, a design-in can have a product life cycle of 24 to 60
months and beyond.
Critical Accounting Policies and Estimates
Management's discussion and analysis of our financial condition and results of
operations is based upon our financial statements which are prepared in
accordance with accounting principles that are 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 and
liabilities, related 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. We continually evaluate our estimates and
judgments, the most critical of which are those related to revenue recognition,
inventory valuation, income taxes and stock-based compensation. We base our
estimates and judgments on historical experience and other factors that we
believe to be reasonable under the circumstances. Materially different results
can occur as circumstances change and additional information becomes known.
We believe that the following accounting policies involve a greater degree of
judgment and complexity than our other accounting policies. Accordingly, these
are the policies we believe are the most critical to understanding and
evaluating our consolidated financial condition and results of operations.
Revenue Recognition
On January 1, 2018, we adopted Financial Accounting Standards Board, or FASB,
Accounting Standards Codification Topic 606, Revenue from Contracts with
Customers, or ASC 606, using the modified retrospective method and accordingly,
modified our policy on revenue recognition as stated below. The primary impact
of adopting ASC 606 for MaxLinear was to accelerate the timing of our revenue
and related cost recognition on products sold via some of our distributors,
which changed from recognition upon the sale to our distributors' end customers,
or the sell-through method, to recognition upon our sale to the distributor, or
the sell-in method. We are also required to estimate the effects of pricing
credits to our distributors from

                                       43

--------------------------------------------------------------------------------

Table of Contents



contractual price protection and unit rebate provisions, as well as stock
rotation rights and record such estimated credits upon our sale to the
distributor. As a result of the adoption of ASC 606 as of January 1, 2018 using
the modified retrospective method, prior period amounts were not adjusted to
reflect the change in revenue recognition for such distributor sales.
Substantially all of our revenue is generated from sales of our integrated
circuits to electronics distributors, module makers, OEMs, and ODMs under
individual customer purchase orders, some of which have underlying master sales
agreements that specify terms governing the product sales. Effective January 1,
2018, we adopted ASC 606 and recognize revenue at the point in time when control
of the products is transferred to the customer at the estimated net
consideration for which collection is probable, taking into account our
customer's rights to price protection, other pricing credits, unit rebates, and
rights to return unsold product. Transfer of control occurs either when products
are shipped to or received by the distributor or direct customer, based on the
terms of the specific agreement with the customer, if we have a present right to
payment and transfer of legal title and the risks and rewards of ownership to
the customer has occurred. For most of our product sales, transfer of control
occurs upon shipment to our distributor or direct customer. In assessing whether
collection of consideration from a customer is probable, we consider the
customer's ability and intention to pay that amount of consideration when it is
due. Payment of invoices is due as specified in the underlying customer
agreement, typically 30 days from the invoice date, which occurs on the date of
transfer of control of the products to the customer. Since payment terms are
less than a year, we have elected the practical expedient and do not assess
whether a customer contract has a significant financing component.
A five-step approach is applied in the recognition of revenue under ASC 606: (1)
identify the contract with a customer, (2) identify the performance obligations
in the contract, (3) determine the transaction price, (4) allocate the
transaction price to the performance obligations in the contract, and (5)
recognize revenue when we satisfy a performance obligation. We applied ASC 606
to our customer contracts that were not completed before the January 1, 2018
adoption date. Customer purchase orders plus the underlying master sales
agreements are considered to be contracts with the customer for purposes of
applying the five-step approach under ASC 606.
Pricing adjustments and estimates of returns under contractual stock rotation
rights are treated as variable consideration for purposes of determining the
transaction price, and are estimated at the time control transfers using the
expected value method based on our analysis of actual price adjustment claims by
distributors and product and historical return rates, and then reassessed at the
end of each reporting period. We also consider whether any variable
consideration is constrained, since such amounts for which it is probable that a
significant reversal will occur when the contingency is subsequently resolved
are required to be excluded from revenues. Price adjustments are finalized at
the time the products are sold through to the end customer and the distributor
or end customer submits a claim to reduce the sale price to a pre-approved net
price. Stock rotation allowances are capped at a fixed percentage of our sales
to a distributor for a period of time, up to six months, as specified in the
individual distributor contract. If our current estimates of such credits and
rights are materially inaccurate, it may result in adjustments that affect
future revenues and gross profits. Returns under our general assurance warranty
of products for a period of one to three years have not been material and
warranty-related services are not considered a separate performance obligation
under the customer contracts. Most of our customers resell our product as part
of their product and thus are tax-exempt, however to the extent we collect and
remit taxes on product sales from customers, we have elected to exclude from the
measurement of transaction price such taxes.
Each distinct promise to transfer products is considered to be an identified
performance obligation for which revenue is recognized upon transfer of control
of the products to the customer. Although customers may place orders for
products to be delivered on multiple dates that may be in different quarterly
reporting periods, all of the orders are scheduled within one year from the
order date. We have opted to not disclose the portion of revenues allocated to
partially unsatisfied performance obligations, which represent products to be
shipped within 12 months under open customer purchase orders, at the end of the
current reporting period as allowed under ASC 606. We have also elected to
record sales commissions when incurred, pursuant to the practical expedient
under ASC 340, as the period over which the sales commission asset that would
have been recognized is less than one year.
Customer contract liabilities consist of obligations to deliver rebates to
customers in the form of units of products, which are included in accrued
expenses and other current liabilities in the consolidated balance sheets. Other
obligations to customers consist of estimates of price protection rights offered
to our end customers, which are included in accrued price protection liability
in the consolidated balance sheets, as well as price adjustments expected to be
claimed by the distributor upon sell-through of the products to their customers,
and amounts expected to be returned by distributors under stock rotation rights,
which are included in accrued expenses and other current liabilities in the
consolidated balance sheets. We also record a right of return asset consist of
amounts representing the products we expect to receive from customers in
returns, which is included in inventory in the consolidated balance sheets, and
is typically settled within six months of transfer of control to the customer,
or the period over which stock rotation rights are based. Upon lapse of the time
period for stock rotations, or the contractual end

to price protection and rebate programs, which is approximately one to two
years, and when we believe unclaimed amounts are no longer subject to payment
and will not be paid, any remaining asset or liability is derecognized by an
offsetting entry to cost of net revenue and net revenue. For additional
disclosures regarding contract liabilities and other obligations to customers,
see Note 15 to our consolidated financial statements.
We assess customer accounts receivable and contract assets for impairment in
accordance with ASC 310-10-35.
Inventory Valuation
We assess the recoverability of our inventory based on assumptions about demand
and market conditions. Forecasted demand is determined based on historical sales
and expected future sales. Inventory is stated at the lower of cost or net
realizable value. Cost is computed using standard cost, which approximates
actual cost on a first-in, first-out basis and net realizable value is the
estimated selling price in the ordinary course of business, less reasonably
predictable costs of completion, disposal and transportation. We reduce our
inventory to its lower of cost or net realizable value on a part-by-part basis
to account for its obsolescence or lack of marketability. Reductions are
calculated as the difference between the cost of inventory and its net
realizable value based upon assumptions about future demand, market conditions
and costs. Once established, these adjustments are considered permanent and are
not revised until the related inventory is sold or disposed of. If actual market
conditions are less favorable than those projected by management, additional
inventory write-downs may be required that may adversely affect our operating
results. If actual market conditions are more favorable, we may have higher
gross profits when products are sold.
Production Masks
Production masks with alternative future uses or discernible future benefits are
capitalized and amortized over their estimated useful life of two years to five
years. To determine if the production mask has alternative future uses or
benefits, we evaluate risks associated with developing new technologies and
capabilities, and the related risks associated with entering new markets.
Production masks that do not meet the criteria for capitalization are expensed
as research and development costs.
Goodwill and Intangible Assets
Goodwill is the excess of the purchase price over the fair value of identifiable
net assets acquired in business combinations accounted for under the acquisition
method. Intangible assets represent purchased intangible assets including
developed technology and in-process research and development, or IPR&D,
technologies acquired or licensed from other companies, customer relationships,
noncompete covenants, backlog, and trademarks and tradenames. Purchased
finite-lived intangible assets are capitalized and amortized over their
estimated useful lives. Technologies acquired or licensed from other companies,
customer relationships, noncompete covenants, backlog, and trademarks and
tradenames are capitalized and amortized over the lesser of the terms of the
agreement, or estimated useful life. We capitalize IPR&D projects acquired as
part of a business combination. On completion of each project, IPR&D assets are
reclassified to developed technology and amortized over their estimated useful
lives.
Impairment of Goodwill and Long-Lived Assets
Goodwill is not amortized but is tested for impairment using either a
qualitative assessment, and/or the two-step method as needed. Step one is the
identification of potential impairment. This involves comparing the fair value
of each reporting unit, which we have determined to be the entity itself, with
its carrying amount, including goodwill. If the fair value of a reporting unit
exceeds the carrying amount, the goodwill of the reporting unit is considered
not impaired and the second step of the impairment test is unnecessary. If the
carrying amount of a reporting unit exceeds its fair value, the second step of
the impairment test is performed to measure the amount of impairment loss, if
any. We test by reporting unit, goodwill and other indefinite-lived intangible
assets for impairment at October 31 each year or more frequently if we believe
indicators of impairment exist.
During development, IPR&D is not subject to amortization and is tested for
impairment annually or more frequently if events or changes in circumstances
indicate that the asset might be impaired. We review indefinite-lived intangible
assets each year for impairment using a qualitative assessment, followed by a
quantitative assessment, as needed, each year as of October 31, the date of our
annual goodwill impairment review, or whenever events or changes in
circumstances indicate the carrying value may not be recoverable. Recoverability
of indefinite-lived intangible assets is measured by comparing the carrying
amount of the asset to its fair value. In certain cases, we utilize the
relief-from-royalty method when appropriate, and a fair value will be obtained
based on analysis over the costs saved by owning the right instead of leasing
it. Once an IPR&D

                                       45

--------------------------------------------------------------------------------

project is complete, it becomes a finite-lived intangible asset and is evaluated
for impairment both immediately prior to its change in classification and
thereafter in accordance with our policy for long-lived assets.
We regularly review the carrying amount of our long-lived assets subject to
depreciation and amortization, as well as the useful lives, to determine whether
indicators of impairment may exist which warrant adjustments to carrying values
or estimated useful lives. An impairment loss would be recognized when the sum
of the expected future undiscounted net cash flows is less than the carrying
amount of the asset. Should impairment exist, the impairment loss would be
measured based on the excess of the carrying amount of the asset over the
asset's fair value.
Income Taxes
We provide for income taxes utilizing the asset and liability approach of
accounting for income taxes. Under this approach, deferred taxes represent the
future tax consequences expected to occur when the reported amounts of assets
and liabilities are recovered or paid. Deferred taxes are presented net as
noncurrent. The provision for income taxes generally represents income taxes
paid or payable for the current year plus the change in deferred taxes during
the year. Deferred taxes result from the differences between the financial and
tax bases of our assets and liabilities and are adjusted for changes in tax
rates and tax laws when changes are enacted. Valuation allowances are recorded
to reduce deferred tax assets when a judgment is made that is considered more
likely than not that a tax benefit will not be realized. A decision to record a
valuation allowance results in an increase in income tax expense or a decrease
in income tax benefit. If the valuation allowance is released in a future
period, income tax expense will be reduced accordingly.
The calculation of tax liabilities involves dealing with uncertainties in the
application of complex global tax regulations. The impact of an uncertain income
tax position is recognized at the largest amount that is "more likely than not"
to be sustained upon audit by the relevant taxing authority. An uncertain income
tax position will not be recognized if it has less than a 50% likelihood of
being sustained. If the estimate of tax liabilities proves to be less than the
ultimate assessment, a further charge to expense would result.
In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. We continue to assess the
need for a valuation allowance on the deferred tax asset by evaluating both
positive and negative evidence that may exist. Any adjustment to the net
deferred tax asset valuation allowance would be recorded in the income statement
for the period that the adjustment is determined to be required.

On December 22, 2017, the Tax Cuts and Jobs Act, or the Tax Act, was enacted
into U.S. tax law. In 2018, we made an
accounting policy election to treat Global Intangible Low Taxed Income in
accordance with the Tax Act as a period cost.
Stock-Based Compensation
We measure the cost of employee services received in exchange for equity
incentive awards, including restricted stock units and restricted stock awards,
employee stock purchase rights and stock options, based on the grant date fair
value of the award. We calculate the fair value of restricted stock units and
performance-based restricted stock units based on the fair market value of our
common stock on the grant date. Stock-based compensation expense is then
determined based on the number of restricted stock units that are expected to
vest; for performance-based restricted stock units, this is the number of units
that are expected to vest during the performance period if it is probable that
we will achieve the performance metrics specified in the underlying award
agreement. We use the Black-Scholes valuation model to calculate the fair value
of stock options and employee stock purchase rights granted to employees.
Stock-based compensation expense is recognized over the period during which the
employee is required to provide services in exchange for the award, which is
usually the vesting period. We recognize compensation expense over the vesting
period using the straight-line method and classify these amounts in the
statements of operations based on the department to which the related employee
reports. We calculate the weighted-average expected life of options using the
simplified method as prescribed by guidance provided by the Securities and
Exchange Commission. This decision was based on the lack of historical data due
to our limited number of stock option exercises under the 2010 Equity Incentive
Plan. We will continue to assess the appropriateness of the use of the
simplified method as we develop a history of option exercises.
Recently Adopted Accounting Pronouncements
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The
amendments in this update require a lessee to recognize in the statement of
financial position a liability to make lease payments (the lease liability) and
a right-of-

use asset representing its right to use the underlying asset. For leases less than twelve months, an entity is permitted to make an accounting policy election by class of underlying asset not to recognize right-of-use assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. We have made this election. Also, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to provide an additional transition method. An entity can elect not to present comparative financial information under Topic 842 if it recognizes a cumulative-effect adjustment to retained earnings upon adoption. We have also made this election. Further, in January 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements, which clarified that post-adoption interim transition disclosures normally required in the year of adoption for the effect of a change in accounting principle on an entity's financial statements are not required for the adoption of ASC 842. The amendments in these updates are effective for us for fiscal years beginning with 2019, including interim periods within those years, with early adoption permitted. We have completed our assessment of the impact of the adoption of ASC 842. Upon adoption, we recognized approximately $24.8 million of right-of-use assets and a net increase of $25.1 million in lease-related liabilities at January 1, 2019. Also, the impact of the adoption of ASC 842 on our accumulated deficit and deferred tax assets at January 1, 2019 was not material. Lastly, the impact of the adoption of ASC 842 on our consolidated results of operations for the year ended December 31, 2019 was not material.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify how to apply certain aspects of the new lease accounting standard. The amendments in this update, among other things, better articulates the requirement for a lessee's reassessment of lease classification as of the effective date of a modification, clarifies that a change to an index or rate for variable lease payments does not constitute a resolution of a contingency that would result in the remeasurement of lease payments, and requires entities that apply Topic 842 retrospectively to each reporting period and do not adopt the practical expedients to write off any prior unamortized initial direct costs that do not meet the definition under Topic 842 to equity. The amendments in this update have the same effective date and transition requirements as the new lease standard summarized above. We have disclosed the impact of adoption of Topic 842 on our consolidated financial position and results of operations as stated above.

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, to clarify the Codification and prevent unintended application of the guidance. An amendment to ASC 718-740, Compensation-Stock Compensation-Income Taxes, clarifies that excess tax benefits should be recognized in the period in which the amount of the deduction is determined. The transition and effective date guidance is based on the facts and circumstances of each amendment. The amendment identified above will be effective for us beginning with fiscal year 2019. The adoption of the amendments in this update in year ended December 31, 2019 did not have a material impact on our consolidated financial position and results of operations.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), which is intended to improve accounting for hedging activities by expanding and refining hedge accounting for both nonfinancial and financial risk components and aligning the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The amendments in this update became effective for us beginning with fiscal year 2019. The amendments in this update were required to be applied prospectively. The adoption of the amendments in this update did not have a material impact on our consolidated financial statements for the year ended December 31, 2019.

In July 2019, the FASB issued ASU No. 2019-07, Codification Updates to SEC Sections-Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization, and Miscellaneous Updates, to align the FASB's Accounting Standards Codification with requirements of certain already effective SEC final rules, which included requiring interim presentation of changes in stockholders' equity and eliminating certain other disclosures. The amendments in ASU No. 2019-07 were effective for us immediately in the third quarter 2019. We previously adopted the related SEC final rules in our 2018 Annual Report and Form 10-Q for the three months ended March 31, 2019. The adoption of the amendments in these updates did not have a material impact on our consolidated financial position, results of operations, and disclosures. Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to require the use of an expected credit loss model that requires consideration of a broader range of information to estimate credit losses over the lifetime of the asset, replacing the current incurred loss methodology of recognizing credit losses that delays recognition until it is probable a loss has been incurred. An entity with trade receivables will be required to use historical loss information, current conditions, and reasonable and supportable forecasts to determine expected lifetime credit losses. Pooling of assets with similar risk characteristics is also required. Also, in

April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, to clarify the inclusion of recoveries of trade receivables previously written off when estimating an allowance for credit losses. The amendments in this update are required to be applied using the modified retrospective method with an adjustment to accumulated deficit and are effective for us beginning with fiscal year 2020, including interim periods. We have performed an assessment of the impact of adoption of the amendments in these updates on our consolidated financial position and results of operations. Based on that assessment, the adoption of the amendments in this update will not have a material impact on our accounts receivable, net and accumulated deficit as of January 1, 2020 and is also not expected to have a material impact on our results of operations for the year ending December 31, 2020.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for us beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement, to improve the fair value measurement reporting of financial instruments. The amendments in this update require, among other things, added disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update eliminate, among other things, disclosure of the reasons for and amounts of transfers between Level 1 and Level 2 for assets and liabilities that are measured at fair value on a recurring basis and an entity's valuation processes for Level 3 fair value measurements. The amendments in this update will be effective for us beginning with fiscal year 2020, with early adoption permitted. Retrospective application is required for all amendments in this update except the added disclosures, which should be applied prospectively. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts. The amendments in this update require the capitalization of implementation costs during the application development stage of such hosting arrangements and amortization of the expense over the term of the arrangement including any option to extend reasonably certain to be exercised or option to terminate reasonably certain not to be exercised. Capitalized implementation costs and amortization thereof are also required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. The amendments in this update will be effective for us beginning with fiscal year 2020, with early adoption permitted. Entities may select retrospective or prospective application to all implementation costs incurred after the adoption date. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740)-Simplifying the Accounting for Income Taxes, to remove certain exceptions and improve consistency of application, including, among other things, requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The amendments in this update will be effective for us beginning with fiscal year 2021, with early adoption permitted. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

Results of Operations
The following describes the line items set forth in our consolidated statements
of operations. A discussion of changes in our results of operations during the
year ended December 31, 2018 compared to the year ended December 31, 2017 has
been omitted from this Annual Report on Form 10-K, but may be found in "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations" in our Annual Report on Form 10-K for the year ended December 31,
2018, filed with the SEC on February 5, 2019, which discussion is incorporated
herein by reference and which is available free of charge on the SEC's website
at www.sec.gov.
Net Revenue. Net revenue is generated from sales of radio-frequency, analog and
mixed-signal integrated circuits for the connected home, wired and wireless
infrastructure, and industrial and multi-market applications. A significant
portion of our sales are to distributors, which then resell our products.
Cost of Net Revenue. Cost of net revenue includes the cost of finished silicon
wafers processed by third-party foundries; costs associated with our outsourced
packaging and assembly, test and shipping; costs of personnel, including
stock-based compensation, and equipment associated with manufacturing support,
logistics and quality assurance; amortization of acquired developed technology
intangible assets and inventory step-ups to fair value; amortization of certain
production mask costs; cost of production load boards and sockets; and an
allocated portion of our occupancy costs.
Research and Development. Research and development expense includes
personnel-related expenses, including stock-based compensation, new product
engineering mask costs, prototype integrated circuit packaging and test costs,
computer-aided design software license costs, intellectual property license
costs, reference design development costs, development testing and evaluation
costs, depreciation expense and allocated occupancy costs. Research and
development activities include the design of new products, refinement of
existing products and design of test methodologies to ensure compliance with
required specifications. All research and development costs are expensed as
incurred.
Selling, General and Administrative. Selling, general and administrative expense
includes personnel-related expenses, including stock-based compensation,
amortization of certain acquired intangible assets, third-party sales
commissions, field application engineering support, travel costs, professional
and consulting fees, legal fees, depreciation expense and allocated occupancy
costs.
Impairment Losses.  Impairment losses consist of charges resulting from the
impairment of acquired intangible assets.
Restructuring Charges. Restructuring charges consist of severance, lease and
leasehold impairment charges, and other charges related to restructuring plans.
Interest and Other Income (Expense), Net. Interest and other income (expense),
net includes interest income, interest expense and other income (expense).
Interest income consists of interest earned on our cash, cash equivalents and
restricted cash balances. Interest expense consists of interest accrued on debt.
Other income (expense) generally consists of income (expense) generated from
non-operating transactions.
Income Tax Provision (Benefit). We make certain estimates and judgments in
determining income tax expense for financial statement purposes. These estimates
and judgments occur in the calculation of certain tax assets and liabilities,
which arise from differences in the timing of recognition of revenue and
expenses for tax and financial statement purposes and the realizability of
assets in future years.

Total net revenue           $    317,180      $ 384,997       (18 )%

Net revenue decreased $67.8 million to $317.2 million for the year ended December 31, 2019, as compared to $385.0 million for the year ended December 31, 2018. The decrease in connected home net revenue of $54.7 million was primarily driven by a slowdown in the cable market, which impacted both cable and related MoCA product shipments, owing to reduced operator spending, the market transition from DOCSIS 3.0 to DOCSIS 3.1 and related customer inventory reductions, and, to a lesser extent, reductions in satellite, tuner, and other connectivity product shipments. The increase in infrastructure revenues of $3.0 million was primarily driven by increased high performance analog and high-speed interconnect shipments in this category. The decrease in industrial and multi-market revenue of $16.1 million was related to decreased shipments of high performance analog products in this category. We currently expect that revenue will fluctuate in the future, from period-to-period, based on evolving customer demand for existing products, the pace of adoption of newer products, and macroeconomic conditions.

% of net revenue              53 %           54 %

Cost of net revenue decreased $26.7 million to $149.5 million for the year ended December 31, 2019, as compared to $176.2 million for the year ended December 31, 2018. The decrease was primarily driven by lower sales. The decrease in gross profit percentage for the year ended December 31, 2019, as compared to the year ended December 31, 2018, was due to lower revenue and product mix. We currently expect that gross profit percentage will fluctuate in the future, from period-to-period, based on changes in product mix, average selling prices, and average manufacturing costs.

% of net revenue                  31 %            31 %


Research and development expense decreased $21.7 million to $98.3 million for the year ended December 31, 2019 from $120.0 million in the year ended December 31, 2018. The decrease was primarily due to decreases in payroll-related expenses of $11.8 million due to lower headcount, prototype expenses of $3.9 million due to timing of projects, depreciation expense of $2.6 million as a result of certain machinery and equipment reaching the end of their useful lives, occupancy expenses of $2.1 million from terminated leases, outside services of $0.6 million, and travel-related expenses of $0.4 million. We expect our research and development expenses to increase in the future as we continue to focus on expanding our product portfolio and enhancing existing products. Selling, General and Administrative


                                       Year Ended December 31,       % Change

                                       (dollars in thousands)

Selling, general and administrative $ 88,762 $ 101,789 (13 )% % of net revenue

                             28 %            26 %


Selling, general and administrative expense decreased $13.0 million to $88.8 million for the year ended December 31, 2019, as compared to $101.8 million for the year ended December 31, 2018. The decrease was primarily due to a decrease in intangible asset amortization of $8.9 million as certain assets reached the end of their useful lives, as well as decreases in payroll-related expense of $1.7 million due to lower headcount, professional fees of $1.3 million, outside services of $0.5 million, and travel-related expenses of $0.3 million. We expect selling, general and administrative expenses to remain relatively flat in the near-term; however, our expenses may increase in the future as we expand our sales and marketing organization to enable market expansion.

The income tax benefit for the year ended December 31, 2019 primarily related to the mix of pre-tax income among jurisdictions, discrete tax benefits related to stock-based compensation, and release of certain reserves for uncertain tax positions under ASC 740-10.



                                       52

--------------------------------------------------------------------------------

Table of Contents



The income tax benefit for the year ended December 31, 2018 primarily related to
a partial release of our valuation allowance and the mix of pre-tax income among
jurisdictions, excess tax benefits related to stock-based compensation, and
release of uncertain tax positions under ASC 740-10.
Liquidity and Capital Resources
As of December 31, 2019, we had cash and cash equivalents of $92.7 million,
restricted cash of $0.4 million, and net accounts receivable of $50.4 million.
Additionally, as of December 31, 2019, our working capital was $115.2 million.
Our primary uses of cash are to fund operating expenses, purchases of inventory,
property and equipment, intangible assets, and from time to time, the
acquisition of businesses. We also use cash to pay down outstanding debt. Our
cash and cash equivalents are impacted by the timing of when we pay expenses as
reflected in the change in our outstanding accounts payable and accrued
expenses. Cash used to fund operating expenses in our consolidated statements of
cash flows excludes the impact of non-cash items such as stock-based
compensation, amortization and depreciation of acquired intangible assets,
leased right-of-use assets and property and equipment, and impairment of
intangible assets and long-lived assets. Cash used to fund acquisitions of
businesses and other capital purchases is included in investing activities in
our consolidated statements of cash flows. Cash used to pay down outstanding
debt is included in financing activities in our consolidated statements of cash
flows.
Our primary sources of cash are cash receipts on accounts receivable from our
shipment of products to distributors and direct customers. Aside from the
amounts billed to our customers, net cash collections of accounts receivable are
impacted by the efficiency of our cash collections process, which can vary from
period to period depending on the payment cycles of our major distributor
customers, and relative linearity of shipments period-to-period. Our credit
agreement, under which we entered into a term loan to partially fund our
acquisition of Exar, permits us to request incremental loans in an aggregate
principal amount not to exceed the sum of $160.0 million (subject to adjustments
for any voluntary prepayments), plus an unlimited amount that is subject to pro
forma compliance with certain secured leverage ratio and total leverage ratio
tests. We have not requested any incremental loans to date.
Following is a summary of our working capital, cash and cash equivalents, and
restricted cash for the periods indicated:
                                                                       December 31,

Cash Flows from Operating Activities
Net cash provided by operating activities was $78.3 million for the year ended
December 31, 2019. Net cash provided by operating activities consisted of
positive cash flow from operations including $101.1 million in non-cash expenses
and $16.9 million in changes in operating assets and liabilities, partially
offset by net loss of $19.9 million and deferred income taxes and excess tax
benefits from stock-based compensation of $19.8 million. Non-cash items included
in net loss for the year ended December 31, 2019 primarily included depreciation
and amortization of property, equipment, intangible assets and leased
right-of-use assets of $66.4 million and stock-based compensation of $32.1
million. During the year ended December 31, 2019, we also exited certain leased
facilities, which resulted in impairment of leased right-of-use assets of $9.2
million and leasehold improvements of $1.4 million, which was partially offset
by a gain on extinguishment of related lease liabilities of $10.4 million, all
of which are non-cash items that did not affect cash flows.
Net cash provided by operating activities was $102.7 million for the year ended
December 31, 2018. Net cash provided by operating activities consisted of
positive cash flow from operations including $100.3 million in non-cash
operating expenses and $28.6 million in changes in operating assets and
liabilities, partially offset by net loss of $26.2 million. Non-cash items
included in net loss for the year ended December 31, 2018 primarily included
depreciation and amortization of property, equipment and intangible assets of
$79.0 million, stock-based compensation of $31.7 million, and impairment of
intangible assets of $2.2 million, partially offset by deferred income taxes of
$12.1 million and excess tax benefits on stock-based awards of $2.0 million.
Cash Flows from Investing Activities
Net cash used in investing activities was $7.0 million for the year ended
December 31, 2019. Net cash used in investing activities primarily consisted of
$6.9 million in purchases of property and equipment.
Net cash used in investing activities was $7.8 million for the year ended
December 31, 2018. Net cash used in investing activities consisted entirely of
$7.8 million in purchases of property and equipment.
Cash Flows from Financing Activities
Net cash used in financing activities was $53.4 million for the year ended
December 31, 2019. Net cash used in financing activities consisted primarily of
cash outflows from aggregate prepayments of principal of $50.0 million and $12.0
million in minimum tax withholding paid on behalf of employees for restricted
stock units, partially offset by cash inflows of $8.6 million in net proceeds
from issuance of common stock upon exercise of stock options.
Net cash used in financing activities was $93.8 million for the year ended
December 31, 2018. Net cash used in financing activities primarily consisted of
cash outflows from $93.0 million in aggregate prepayments of principal on
outstanding debt and $7.6 million in minimum tax withholding paid on behalf of
employees for restricted stock units, partially offset by cash inflows of $6.8
million in net proceeds from issuance of common stock upon exercise of stock
options.
We believe that our $92.7 million of cash and cash equivalents at December 31,
2019 will be sufficient to fund our projected operating requirements for at
least the next twelve months. We have repaid $213.0 million of debt to date. The
credit agreement permits the Company to request incremental loans in an
aggregate principal amount not to exceed the sum of $160.0 million (subject to
adjustments for any voluntary prepayments), plus an unlimited amount that is
subject to pro forma compliance with certain secured leverage ratio and total
leverage ratio tests. Incremental loans are subject to certain additional
conditions, including obtaining additional commitments from the lenders then
party to the credit agreement or new lenders. The term loan facility has a
seven-year term and bears interest at either an Adjusted LIBOR or an Adjusted
Base Rate, at our option, plus a fixed applicable margin.
Our cash and cash equivalents in recent years have been favorably affected by
our implementation of an equity-based bonus program for our employees, including
executives. In connection with that bonus program, in February 2019, we issued
0.3 million freely-tradable shares of our common stock in settlement of bonus
awards for the 2018 performance period. We expect to implement a similar
equity-based plan for fiscal 2019, but our compensation committee retains
discretion to effect payment in cash, stock, or a combination of cash and stock.

Notwithstanding the foregoing, we may need to raise additional capital or incur
additional indebtedness to fund strategic initiatives or operating activities,
particularly if we continue to pursue acquisitions. Our future capital
requirements will depend on many factors, including our rate of revenue growth,
the expansion of our engineering, sales and marketing activities, the timing and
extent of our expansion into new territories, the timing of introductions of new
products and enhancements to existing products, the continuing market acceptance
of our products and potential material investments in, or acquisitions of,
complementary businesses, services or technologies. Additional funds may not be
available on terms favorable to us or at all. If we are unable to raise
additional funds when needed, we may not be able to sustain our operations or
execute our strategic plans.
Warranties and Indemnifications
In connection with the sale of products in the ordinary course of business, we
often make representations affirming, among other things, that our products do
not infringe on the intellectual property rights of others, and agree to
indemnify customers against third-party claims for such infringement. Further,
our certificate of incorporation and bylaws require us to indemnify our officers
and directors against any action that may arise out of their services in that
capacity, and we have also entered into indemnification agreements with respect
to all of our directors and certain controlling persons.
Off-Balance Sheet Arrangements
As part of our ongoing business, we do not participate in transactions that
generate relationships with unconsolidated entities or financial partnerships,
such as entities often referred to as structured finance or special purpose
entities, or SPEs, which would have been established for the purpose of
facilitating off-balance sheet arrangements or other contractually narrow or
limited purposes. As of December 31, 2019, we were not involved in any
unconsolidated SPE transactions.
Contractual Obligations

Our consolidated balance sheet at December 31, 2019 included $6.6 million in other long-term liabilities for uncertain tax positions, some of which may result in cash payment. The future payments related to uncertain tax positions recorded as other long-term liabilities have not been presented in the table above due to the uncertainty of the amounts and timing of cash settlement with the taxing authorities.
