Organization and Summary of Significant Accounting Policies

1.	Organization and Summary of Significant Accounting Policies

Organization and Basis of Presentation

We are a leading worldwide developer and supplier of custom-designed semiconductor solutions that enable people to interact more easily and intuitively with a wide variety of mobile computing, communications, entertainment, and other electronic devices. We currently generate revenue from the markets for Internet of Things, or IoT, products, which include smart devices with voice, speech, video, wireless connectivity, smartphones, tablets, personal computer, or PC, products, and other select electronic devices, including devices in automobiles. We deliver semiconductor solutions including connectivity products, audio input and output System-On-Chips, or SoCs, high-definition video and vision SoCs, touch controllers, display drivers, fingerprint sensors, and touchpads, which comprise our semiconductor chip, firmware, and software as a complete customer solution.

The consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, and include our financial statements and those of our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation.

Our fiscal year is the 52- or 53-week period ending on the last Saturday in June. The fiscal years presented in this report were 52-week periods ended June 27, 2020 and June 29, 2019 and a 53-week period ended June 30, 2018.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments, contingent consideration liability and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, including our expectations regarding the potential impacts on our business of the COVID-19 pandemic, 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 may differ from these estimates under different assumptions or conditions.

Cash Equivalents and Investments

Cash equivalents consist of highly liquid investments with original maturities of three months or less.

Our cash equivalents as of the end of fiscal 2020 and 2019 are money market accounts with a fair value of $521.1 million and $313.7 million, respectively.

Fair Value

We measure certain financial assets and liabilities at fair value. When we measure fair value on either a recurring or nonrecurring basis, inputs used in valuation techniques are assigned a hierarchical level as follows:

•

Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets.

•

Level 2 inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•

Level 3 inputs are unobservable inputs reflecting our assumptions, which are incorporated into valuation techniques and models used to determine fair value. The assumptions are consistent with market participant assumptions that are reasonably available.

Our financial assets measured at fair value are money markets, are included on a recurring basis, and are level 1 within the fair value hierarchy. As of the end of fiscal 2020 and 2019 our money market balances were $521.1 million and $313.7 million, respectively.

There were no transfers in or out of our Level 1, 2 or 3 assets during fiscal 2020 or 2019.

The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated. The interest rate on our bank debt is variable, which is subject to change from time to time to reflect a market interest rate; accordingly, the carrying value of our bank debt approximates fair value.

The fair value of our $525.0 million principal amount of 0.50% convertible notes due 2022 is measured at fair value for disclosure purposes. The fair value of the convertible notes as of June 27, 2020 was approximately $542.5 million, based on the last trading price of the convertible notes for the period.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, investments, and accounts receivable. Our investment policy, which is predicated on capital preservation and liquidity, limits investments to U.S. government treasuries and agency issues, taxable securities, and municipal issued securities with a minimum rating of A1 (Moody’s) or P1 (Standard and Poor’s) or their equivalent.

We sell our products to contract manufacturers that provide manufacturing services for OEMs, to some OEMs directly, and to distributors. We extend credit based on an evaluation of a customer’s financial condition, and we generally do not require collateral.

The following customers accounted for more than 10% of our accounts receivable balance as of the end of fiscal 2020 and 2019:

	2020	2019
Customer A	21%	*
Customer B	18%	*
Customer C	*	25%
Customer D	*	16%

*	Less than 10%

Other Concentrations

Our products include certain components that are currently single sourced. We believe other vendors would be able to provide similar components, however, the qualification of such vendors may require additional lead time. In order to mitigate any potential adverse impact from a supply disruption, we strive to maintain an adequate supply of critical single-sourced components.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board, or FASB, issued an Accounting Standards Update, or ASU, on revenue from contracts with customers, ASU No. 2014-09, Revenue from Contracts with Customers, or the new revenue standard. The new revenue standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers.

We adopted the new revenue standard at the beginning of our fiscal 2019, using the modified retrospective method applied to all contracts not completed as of the adoption date. Results for reporting periods ending after our fiscal 2018 are presented under the new revenue standard, while prior reporting periods are not adjusted and continue to be reported in accordance with the previous revenue standard. Recognition of revenue has remained substantially unchanged under the new revenue standard as compared to the previous revenue standard. Accordingly, there was no adjustment to the fiscal 2019 opening retained earnings.

Our revenue is primarily generated from the sale of ASIC chips, either directly to a customer or to a distributor. Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to receive in exchange for those goods or services. All of our revenue, except an inconsequential amount, is recognized at a point in time, either on shipment or delivery of the product, depending on customer terms and conditions. We generally warrant our products for a period of 12 months from the date of sale and estimate probable product warranty costs at the time we recognize revenue as the warranty is considered an assurance warranty and not a performance obligation. Non-product revenue is recognized over the same period of time such performance obligations are satisfied. We then select an appropriate method for measuring satisfaction of the performance obligations.

Revenue from sales to distributors is recognized upon shipment of the product to the distributors (sell-in basis). Master sales agreements are in place with certain customers, and these agreements typically contain terms and conditions with respect to payment, delivery, warranty and supply. In the absence of a master sales agreement, we consider a customer's purchase order or our standard terms and conditions to be the contract with the customer.

Our pricing terms are negotiated independently, on a stand-alone basis. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration which we expect to receive for the sale of such products. In limited situations, we make sales to certain customers under arrangements where we grant stock rotation rights, price protection and price allowances; variable consideration associated with these rights is expected to be inconsequential. These adjustments and incentives are accounted for as variable consideration, classified as other current liabilities under the new revenue standard and are shown as customer obligations in other accrued liabilities on our consolidated balance sheets. We estimate the amount of variable consideration for such arrangements based on the expected value to be provided to customers, and we do not believe that there will be significant changes to our estimates of variable consideration. When incentives, stock rotation rights, price protection, volume discounts, or price allowances are applicable, they are estimated and recorded in the period the related revenue is recognized. Stock rotation reserves are based on historical return rates and recorded as a reduction to revenue with a corresponding reduction to cost of goods sold for the estimated cost of inventory that is expected to be returned and recorded as prepaid expenses and other current assets. In limited circumstances, we enter into volume-based tiered pricing arrangements and we estimate total unit volumes under such arrangement to determine the expected transaction price for the units expected to be transferred. Such arrangements are accounted for as contract liabilities within other accrued liabilities. Sales returns liabilities are recorded as refund liabilities within other accrued liabilities.

Our accounts receivable balance is from contracts with customers and represents our unconditional right to receive consideration from customers. Payments are generally due within three months of completion of the performance obligation and subsequent invoicing and, therefore, do not include significant financing components. In fiscal 2020, there was no material bad debt charge recorded on accounts receivable. There was $0.4 million of contract assets (i.e., unbilled accounts receivable, deferred commissions) recorded on the consolidated balance sheets as of June 27, 2020, and $0.9 million as of June 29, 2019. Contract assets are presented as part of prepaid expenses and other current assets. Contract liabilities and refund liabilities were $3.2 million and $25.8 million, respectively, as of June 27, 2020, and $4.5 million and $47.5 million, respectively, as of June 29, 2019. Both contract liabilities and refund liabilities are presented as part of customer obligations in other accrued liabilities on our consolidated balance sheets. During fiscal 2020 and 2019, we recognized $2.0 million and $0.3 million, respectively, in revenue related to contract liabilities outstanding as of the beginning of each such fiscal year.

We invoice customers for each delivery upon shipment and recognize revenue in accordance with delivery terms. As of June 27, 2020, we did not have any remaining unsatisfied performance obligations with an original duration greater than one year. Accordingly, under the optional exception provided by the ASC, we do not disclose revenues allocated to future performance obligations of partially completed contracts. We have elected to account for shipping and handling costs as fulfillment costs before the customer obtains control of the goods. We continue to classify shipping and handling costs as a cost of revenue. We have elected to continue to account for collection of all taxes on a net basis.

We incur commission expense that is incremental to obtaining contracts with customers. Sales commissions (which are recorded in the selling, general and administrative expense line item in the consolidated statements of operations) are expensed when the product is shipped because such commissions are incurred after the product has been shipped.

Revenue from contracts with customers disaggregated by geographic area based on customer location and groups of similar products is presented in Note 12 Segment, Customers, and Geographical Information.

Advertising Costs

Advertising costs, if any, are expensed when incurred.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations. On an ongoing basis, we evaluate the collectability of accounts receivable based on a combination of factors. In circumstances in which we are aware of a specific customer’s potential inability to meet its financial obligation, we record a specific reserve of the bad debt against amounts due. In addition, we make judgments and estimates on the collectability of accounts receivable based on our historical bad debt experience, customers’ creditworthiness, current economic trends, recent changes in customers’ payment trends, and deterioration in customers’ operating results or financial position. If circumstances change adversely, additional bad debt allowances may be required. For the fiscal year ended June 27, 2020, credit losses on our accounts receivable were $3.7 million and were insignificant in prior periods presented, and we believe that an adequate allowance for doubtful accounts has been provided.

Cost of Revenue

Our cost of revenue includes the cost of products shipped to our customers, which primarily includes the cost of products built to our specifications by our contract manufacturers, the cost of silicon wafers supplied by independent semiconductor wafer manufacturers, and the related assembly, package, and test costs of our products. Also included in our cost of revenue are personnel and related costs, including share-based compensation for quality assurance and manufacturing support personnel; logistics costs; depreciation of equipment supporting manufacturing; acquired intangibles amortization; fair value adjustments associated with acquired businesses; inventory write-downs and losses on purchase obligations; and warranty costs.

Inventories

Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value as of the end of fiscal 2020 and 2019, and consisted of the following (in millions):

	2020		2019
Raw materials and work-in-progress	$	53.6	$	110.7
Finished goods		48.4		48.0
	$	102.0	$	158.7

We record a write-down, if necessary, to reduce the carrying value of inventory to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory, which we do not subsequently write-up. We also record a liability and charge to cost of revenue for estimated losses on inventory we are obligated to purchase from our contract manufacturers when such losses become probable from customer delays, order cancellations, or other factors. The following factors influence our estimates: changes to or cancellations of customer orders, unexpected or sudden decline in demand, rapid product improvements, technological advances, and termination or changes by our OEM customers of any product offerings incorporating our product solutions.

Property and Equipment

We state property and equipment at cost less accumulated depreciation and amortization. We compute depreciation using the straight-line method over the estimated useful lives of the assets. We amortize leasehold improvements over the shorter of the lease term or the useful life of the asset.

Other Assets

In April 2017, we paid $18.4 million for a 14.4% interest in OXi Technology Ltd., or OXi. In April 2019, our investment ownership was reduced to 13.8% as a result of new investment in OXi. Our investment in OXi is included in non-current other assets on our consolidated balance sheets. We determined the equity method of accounting applies to our investment as we have significant influence over OXi’s operating and financial policies. We record our portion of OXi’s net income/(loss) on a one quarter lag due to the timing of the availability of OXi’s financial records. In addition, we amortize intangible assets that we recorded under the equity method of accounting, and such amortization as well as our portion of Oxi’s net income/(loss) is included in equity investment loss on our consolidated statements of operations. As of June 27, 2020, we did not have any material related party transactions with OXi. As our investment in OXi is not material in relation to our financial position or results of operations, we have not summarized information as to the assets, liabilities and results of operations of OXi.

Foreign Currency

The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. These foreign currency transactions and remeasurement gains and losses, resulted in a net gain of $0.2 million in fiscal 2020 and a net loss of $1.1 million in each of fiscal 2019 and 2018. Gains and losses resulting from foreign currency transactions are included in selling, general, and administrative expenses in the consolidated statements of operations.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired. Changes in our goodwill balance for fiscal 2020 and 2019 were as follows (in millions):

	2020			2019
Beginning balance	$	372.8		$	372.8
Goodwill allocated to sale of product line		(12.0	)		—
Ending balance	$	360.8		$	372.8

We have allocated our goodwill to two reporting units. We perform a qualitative assessment of the goodwill in the fourth quarter of each fiscal year, or earlier if a triggering event occurs. In assessing the qualitative factors, we considered the impact of key factors including change in industry and competitive environment, potential impacts on our business of the COVID-19 pandemic, market capitalization, stock price, gross margin and cash flow from operating activities. During fiscal 2020, the sale of TDDI was a triggering event which required us to allocate goodwill to TDDI which was included in the gain on sale of the product line. During our qualitative assessment in fiscal 2020, we determined there were no additional triggering events which led us to performing a step 1 quantitative assessment. We concluded that the fair value of each reporting unit exceeded its carrying amount by a significant amount, therefore, there was no need for impairment. No goodwill impairment was recognized for fiscal 2020, 2019, and 2018.

Impairment of Long-Lived Assets

We evaluate long-lived assets, such as property and equipment and intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. We measure recoverability of assets to be held and used by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. We review the carrying value of indefinite-lived intangible assets for impairment at least annually during the last quarter of our fiscal year, or more frequently if we believe indicators of impairment exist. If the carrying amount of the asset exceeds its estimated undiscounted future cash flows, we recognize an impairment charge in an amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell and would no longer be depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets. No impairment of long-lived assets was recognized for fiscal 2020, 2019 and 2018.

Leases

We determine if a contract is a lease or contains a lease at the inception of the contract and reassess that conclusion if the contract is modified. All leases are assessed for classification as an operating lease or a finance lease. Operating lease right-of-use, or ROU, assets are included in non-current other assets on our consolidated balance sheet. Operating lease liabilities are separated into a current portion, included within other accrued liabilities on our consolidated balance sheet, and a non-current portion, included within other long-term liabilities on our consolidated balance sheet. We do not have any finance lease ROU assets or liabilities. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We do not obtain and control the right to use the identified asset until the lease commencement date.

Our lease liabilities are recognized at the applicable lease commencement date based on the present value of the lease payments required to be paid over the lease term. Because the interest rate implicit in the lease is not readily determinable, we generally use our incremental borrowing rate to discount the lease payments to present value. The estimated incremental borrowing rate is derived from information available at the lease commencement date. We factor in publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Our ROU assets are also recognized at the applicable lease commencement date. The ROU asset equals the carrying amount of the related lease liability, adjusted for any lease payments made prior to lease commencement and lease incentives provided by the lessor. Variable lease payments are expensed as incurred and do not factor into the measurement of the applicable ROU asset or lease liability.

The term of our leases equals the non-cancellable period of the lease, including any rent-free periods provided by the lessor, and also include options to renew or extend the lease (including by not terminating the lease) that we are reasonably certain to exercise. We establish the term of each lease at lease commencement and reassess that term in subsequent periods if a triggering event occurs. Operating lease cost for lease payments is recognized on a straight-line basis over the lease term.

Our lease contracts often include lease and non-lease components. For our leases, we have elected the practical expedient offered by the standard to not separate lease from non-lease components and account for them as a single lease component.

We have elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.

Other Accrued Liabilities and Other Long-Term Liabilities

As of the end of fiscal 2020 and 2019, other accrued liabilities consisted of the following (in millions):

	2020		2019
Customer obligations	$	29.0	$	52.0
Inventory obligations		27.9		26.7
Warranty		3.9		4.0
Other		30.2		23.4
	$	91.0	$	106.1

As of the end of fiscal 2020 and 2019, other long-term accrued liabilities consisted of the following (in millions):


	2020		2019
Income taxes payable, long-term	$	16.4	$	16.2
Operating lease liabilities, long-term		14.6		—
Other		13.0		14.1
	$	44.0	$	30.3

Retention Costs

Retention costs reflect the cost associated with retention agreements entered into with key employees designed to ensure their continued commitment to the support and management of the operations of the company during the transition to new executive leadership. The retention period for employees covered under the retention program continues through November 2020. For the year ended June 27, 2020, retention costs were recorded in the following areas: cost of revenue $0.5 million, research and development $8.4 million and selling, general and administrative $5.0 million. For the year ended June 29, 2019, retention costs were previously reported as one separate line in operating expenses and were reclassified in this report to be consistent with the current year presentation and were recorded in the following areas: research and development $1.5 million and selling, general and administrative $0.9 million. There were no retention costs in the year ended June 30, 2018.

Segment Information

We operate in one segment: the development, marketing, and sale of human interface semiconductor solutions for electronic devices and products. The chief operating decision maker, or CODM, at the beginning of our fiscal year ended June 27, 2020 was our Board of Directors collectively, on a temporary basis until our new chief executive officer, or CEO, was hired in August 2019, whereupon our CEO became the CODM. Our CODM evaluates financial performance and allocates resources using financial information reported on a company-wide basis.

Share-Based Compensation

We charge the estimated fair value less actual forfeitures to earnings on a straight-line basis over the vesting period of the entire underlying award, which is generally three to four years for our restricted stock units, or RSU, awards and stock options, three years for our market stock units, or MSU, awards, three years for our performance stock units, or PSU, awards, up to two years for shares purchased under our 2010 employee stock purchase plan and up to one year for shares purchased under our 2019 employee stock purchase plan .

We estimate the fair value of market-based MSUs at the date of grant using a Monte Carlo simulation model and amortize those fair values over the requisite service period, which is generally three years. The Monte Carlo simulation model that we use to estimate the fair value of market-based MSUs at the date of grant incorporates into the valuation the possibility that the market condition may not be satisfied. Provided that the requisite service is rendered, the total fair value of the market-based MSUs at the date of grant must be recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria.

We recognize compensation expense for phantom stock units on a straight-line basis for each tranche of each award based on the average closing price of our common stock over the thirty calendar days ended prior to each balance sheet date.

We utilize the Black-Scholes option pricing model to estimate the grant date fair value of stock options granted to employees, which requires the input of highly subjective assumptions, including expected volatility and expected life. Historical and implied volatilities were used in estimating the fair value of our stock option awards. The contractual life of our outstanding options is seven years. No options were granted in fiscal 2020 or 2019.

Income Taxes

We account for income taxes under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect of a change in tax rates in income on deferred tax assets and liabilities in the period that includes the enactment date. We establish valuation allowances when necessary to reduce deferred tax assets to the amounts that are more likely than not to be realized.

We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement with a taxing authority. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of highly complex tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our consolidated financial position, results of operations, and cash flows. We believe we have adequately provided for reasonably foreseeable outcomes in connection with the resolution of income tax uncertainties. However, our results have in the past, and could in the future, include favorable and unfavorable adjustments to our estimated tax liabilities in the period a determination of such estimated tax liability is made or resolved, upon the filing of an amended return, upon a change in facts, circumstances, or interpretation, or upon the expiration of a statute of limitation. Accordingly, our effective tax rate could fluctuate materially from period to period.

The computation of basic and diluted net income/(loss) per share for fiscal 2020, 2019, and 2018 was as follows (in millions, except per share amounts):

	2020		2019			2018

Basic	$	3.54	$	(0.66	)	$	(3.63	)
Diluted	$	3.41	$	(0.66	)	$	(3.63	)

Diluted net income per share does not include the effect of potential common shares related to certain share-based awards for fiscal 2020, 2019, and 2018 as follows (in millions):

		2020				2019				2018
Share-based awards			0.7				2.2				2.3

These share-based awards were not included in the computation of diluted net income per share because the proceeds received, if any, from such share-based awards combined with the average unamortized compensation costs, were greater than the average market price of our common stock, and therefore, their effect would have been antidilutive.

Our basic net income per share amounts for each period presented have been computed using the weighted average number of shares of common stock outstanding. Our diluted net income per share amounts for each period presented include the weighted average effect of potentially dilutive shares. We used the “treasury stock” method to determine the dilutive effect of our stock options, RSUs, MSUs, PSUs and our convertible notes.

Debt

Debt Disclosure [Abstract]

Debt

Convertible Debt

On June 20, 2017, we entered into a purchase agreement, or the Purchase Agreement, with Wells Fargo Securities, LLC, as representative of the initial purchasers named therein, or collectively, the Initial Purchasers, pursuant to which we issued and sold, and the Initial Purchasers purchased, $500 million aggregate principal amount of our 0.50% convertible senior notes due 2022, or the Notes, in a private placement transaction. Pursuant to the Purchase Agreement, we also granted the Initial Purchasers a 30-day option to purchase up to an additional $25 million aggregate principal amount of Notes, which was exercised in full on June 21, 2017. The net proceeds, after deducting the Initial Purchasers’ discounts, were $514.5 million, which included proceeds from the Initial Purchasers’ exercise of their option to purchase additional Notes. We received the net proceeds on June 26, 2017, which we used to repurchase 1,698,400 shares of our common stock, to retire our outstanding bank debt, and to provide additional cash resources to fund the Conexant and Marvell Business Acquisitions.

The Notes bear interest at a rate of 0.50% per year. Interest accrued from June 26, 2017, and is payable semi-annually in arrears, on June 15 and December 15 of each year, beginning on December 15, 2017. The Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any our liabilities that are not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries.

The Notes will mature on June 15, 2022, or the Maturity Date, unless earlier repurchased, redeemed or converted.

Holders may convert all or any portion of their Notes, in multiples of $1,000 principal amounts, at their option at any time prior to the close of business on the business day immediately preceding March 15, 2022 under certain defined circumstances.

On or after March 15, 2022 until the close of business on the business day immediately preceding the Maturity Date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amounts, at the option of the holder. Upon conversion, we will pay or deliver, at our election, shares of common stock, cash, or a combination of cash and shares of common stock.

The conversion rate for the Notes is initially 13.6947 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $73.02 per share of common stock). The conversion rate is subject to adjustment in certain circumstances.

Upon the occurrence of a fundamental change (as defined in the Notes indenture), holders of the Notes may require us to repurchase for cash all or a portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the fundamental change repurchase date.

Commencing June 20, 2020, we may redeem for cash all or any portion of the Notes, at our option, if the last reported sale price of our common stock, as determined by us, has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest up to, but excluding, the redemption date. This criteria has not been met as of June 27, 2020. Our policy is to settle the principal amount of our Notes with cash upon conversion or redemption.

As of the issuance date of the Notes, we recorded $82.1 million of the principal amount to equity, representing the debt discount for the difference between our estimated nonconvertible debt borrowing rate of 4.39% and the coupon rate of the Notes of 0.50% using a five-year life, which coincides with the term of the Notes. In addition, we allocated the total of $11.1 million of debt issuance costs, consisting of the Initial Purchaser’s discount of $10.5 million and legal, accounting, and printing costs of $579,000, pro rata, to the equity and debt components of the Notes, or $1.9 million and $9.2 million, respectively. The debt discount and the debt issuance costs allocated to the debt component are amortized as interest expense using the effective interest method over five years.

The contractual interest expense and amortization of discount on the Notes for fiscal 2020, were as follows (in millions):

	Fiscal
	2020
Interest expense	$	2.6
Amortization of discount and debt issuance costs		18.3
Total interest	$	20.9

The unamortized amounts of the debt issuance cost and discount associated with the Notes as of June 27, 2020, were $3.8 million and $34.5 million, respectively.

Revolving Credit Facility

In February 2020, we entered into the First Amendment to Amended and Restated Credit Agreement, or the Amendment, with the lenders that are party thereto, or the Lenders, and Wells Fargo Bank, National Association, as administrative agent for the Lenders, related to that certain Amended and Restated Credit Agreement, dated September 27, 2017, or the Credit Agreement. Pursuant to the Amendment, the Credit Agreement was amended to, among other things, (i) modify the definition of Consolidated EBITDA (as defined in the Credit Agreement) to increase the maximum limit on the add back of certain restructuring and integration cost and expenses to 30% from 15% of Consolidated EBITDA, (ii) modify the negative covenant for Consolidated Total Leverage Ratio (as defined in the Credit Agreement) at the end of any fiscal quarter to 4.75:1.00 from 3.50:1.00, and for any four quarter period following a Material Acquisition (as defined in the Credit Agreement) to 5:00:1.00 from 3.75:1.00, (iii) modify the circumstances under which the maturity date of the Credit Agreement would be accelerated in advance of the maturity date of the Notes to eliminate the acceleration of the maturity date of the Credit Agreement if we meet certain specified leverage and liquidity covenants, (iv) add a minimum liquidity covenant for each two-week period beginning on the date that is 120 days prior to the maturity date of the Notes, (v) add certain technical amendments to address LIBOR transition matters, and (vi) include or revise certain definitions and certain customary representation, warranties and acknowledgments.

The Credit Agreement provides for a revolving credit facility in a principal amount of up to $200 million, which includes a $20 million sublimit for letters of credit and a $20 million sublimit for swingline loans. Under the terms of the Credit Agreement, we may, subject to the satisfaction of certain conditions, request increases in the revolving credit facility commitments in an aggregate principal amount of up to $100 million to the extent existing or new lenders agree to provide such increased or additional commitments, as applicable. Future proceeds under the revolving credit facility are available for working capital and general corporate purposes. As of June 27, 2020, there was a $100.0 million balance outstanding under the revolving credit facility. The weighted average annualized interest rate on these borrowings for the year ended June 27, 2020 was 2.75%.

The revolving credit facility is required to be repaid in full on the earlier of (i) September 27, 2022, and (ii) the date 91 days prior to the Maturity Date of the Notes if the Notes have not been refinanced in full by such date, subject to certain exceptions. Debt issuance costs relating to the revolving credit facility of $2.3 million, included in non-current other assets on our consolidated balance sheet, are being amortized over 60 months.

Our obligations under the Credit Agreement are guaranteed by the material domestic subsidiaries of our company, subject to certain exceptions (such material subsidiaries, together with our company, collectively, the Credit Parties). The obligations of the Credit Parties under the Credit Agreement and the other loan documents delivered in connection therewith are secured by a first priority security interest in substantially all of the existing and future personal property of the Credit Parties, including, without limitation, 65% of the voting capital stock of certain of the Credit Parties’ direct foreign subsidiaries, subject to certain exceptions.

The revolving credit facility bears interest at our election of a Base Rate plus an Applicable Margin or LIBOR plus an Applicable Margin. Swingline loans bear interest at a Base Rate plus an Applicable Margin. The Base Rate is a floating rate that is the greater of the Prime Rate, the Federal Funds Rate plus 50 basis points, or LIBOR plus 100 basis points. The Applicable Margin is based on a sliding scale which ranges from 0.25 to 100 basis points for Base Rate loans and 100 basis points to 175 basis points for LIBOR loans. We are required to pay a commitment fee on any unused commitments under the Credit Agreement which is determined on a leverage-based sliding scale ranging from 0.175% to 0.25% per annum. Interest and fees are payable on a quarterly basis. The LIBOR index is expected to be discontinued at the end of 2021. Under our credit facility, when the LIBOR index is discontinued, we will switch to a comparable or successor rate as selected by us and the Administrative Agent, which may include the Secured Overnight Financing Rate, or SOFR.

Under the Credit Agreement, there are various restrictive covenants, including three financial covenants which limit the consolidated total leverage ratio, or leverage ratio, the consolidated interest coverage ratio, or interest coverage ratio, a restriction which places a limit on the amount of capital expenditures that may be made in any fiscal year, a restriction that permits up to $50 million per fiscal quarter of accounts receivable financings, and sets the Specified Leverage Ratio. The leverage ratio is the ratio of debt as of the measurement date to earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four consecutive quarters ending with the quarter of measurement. The current leverage ratio shall not exceed 4.75 to 1.00 provided that for the four fiscal quarters ending after the date of a material acquisition, such maximum leverage ratio shall be adjusted to 5.0 to 1.00, and thereafter 4.75 to 1.0. The interest coverage ratio is EBITDA to interest expense for the four consecutive quarters ending with the quarter of measurement. The interest coverage ratio must not be less than 3.50 to 1.0 during the term of the Credit Agreement. The Specified Leverage Ratio is the ratio used in determining, among other things, whether we are permitted to make dividends and/or prepay certain indebtedness, at a fixed ratio of 2.25 to 1.00 As of June 27, 2020, we were in compliance with the restrictive covenants.

On June 29, 2019, we adopted Accounting Standards Codification Topic 842, or ASC 842, Leases, which requires recognition of ROU assets and lease liabilities for most leases on our consolidated balance sheet. We adopted ASC 842 using a modified retrospective transition approach as of the effective date as permitted. As a result, we were not required to adjust our comparative period financial information for effects of the standard or make the new required lease disclosures for the periods before the date of adoption. We elected the package of practical expedients which allows us not to reassess (1) whether existing or expired contracts, as of the adoption date, contain leases, (2) the lease classification for existing leases, and (3) whether existing initial direct costs meet the new definition. We also elected the practical expedient to not separate lease and non-lease components for our leases, and to not recognize ROU assets and liabilities for short-term leases.

The most significant impact of the adoption of the standard was the recognition of ROU assets and lease liabilities for operating leases on our consolidated balance sheet. Adoption of the standard did not have a material impact on our consolidated statements of operations or cash flows.

The adoption of this new standard at June 29, 2019, resulted in the following changes:

•

assets increased by $27.8 million, primarily representing the recognition of ROU assets for operating leases; and

•

liabilities increased by $28.4 million, primarily representing the recognition of lease liabilities for operating leases.

Our leases mainly include our worldwide office and research and development facilities which are all classified as operating leases. Certain leases include renewal options that are under our discretion. The leases expire at various dates through fiscal year 2028, some of which include options to extend the lease for up to 5 years. For the fiscal year ended June 27, 2020, we recorded approximately $8.8 million of operating leases expense. Our short-term leases are immaterial and we do not have finance leases.

As of June 27, 2020, the components of leases are as follows (in millions):

	June
	2020
Operating lease right-of-use assets	$	21.0
Operating lease liabilities	$	6.5
Operating lease liabilities, long-term		14.6
Total operating lease liabilities	$	21.1

Supplemental cash flow information related to leases is as follows (in millions):


	Fiscal
	2020
Cash paid for operating leases included in operating cash flows	$	8.4
Supplemental non-cash information related to lease liabilities arising from obtaining right-of-use assets		2.9

As of June 27, 2020, the weighted average remaining lease term was 4.09 years, and the weighted average discount rate was 4.01%.

Future minimum lease payments for the operating lease liabilities are as follows (in millions):

	Operating
	Lease
Fiscal Year	Payments
2021	$	7.2
2022		6.7
2023		3.6
2024		2.1
2025		1.1
Thereafter		2.1
Total future minimum operating lease payments		22.8
Less: interest		(1.7	)
Total lease liabilities	$	21.1

We recognized rent expense on a straight-line basis of $10.3 million, and $12.0 million for fiscal 2019 and 2018, respectively.

As of June 29, 2019, prior to the adoption of ASC 842, future minimum lease payments under non-cancelable operating leases were as follows (in millions):

	Operating
	Lease
Fiscal Year	Payments
2020	$	7.4
2021		3.2
2022		0.9
2023		0.3

Total future minimum operating lease payments	$	11.9

Contingencies

We have in the past and may in the future receive notices from third parties that claim our products infringe their intellectual property rights. We cannot be certain that our technologies and products do not and will not infringe issued patents or other proprietary rights of third parties.

Any infringement claims, with or without merit, could result in significant litigation costs and diversion of management and financial resources, including the payment of damages, which could have a material adverse effect on our business, financial condition, and results of operations.

Indemnifications

In connection with certain agreements, we are obligated to indemnify the counterparty against third party claims alleging infringement of certain intellectual property rights by us. We have also entered into indemnification agreements with our officers and directors. Maximum potential future payments under these agreements cannot be estimated because these agreements do not have a maximum stated liability. However, historical costs related to these indemnification provisions have not been significant. We have not recorded any liability in our consolidated financial statements for such indemnification obligations.

Equity [Abstract]

Stockholders' Equity

8.	Stockholders’ Equity

Preferred Stock

We are authorized, subject to limitations imposed by Delaware law, to issue up to a total of 10,000,000 shares of preferred stock in one or more series without stockholder approval. Our Board of Directors has the power to establish, from time to time, the number of shares to be included in each series and to fix the rights, preferences, and privileges of the shares of each wholly unissued series and any of its qualifications, limitations, or restrictions. Our Board of Directors can also increase or decrease the number of shares of a series, but not below the number of shares of that series then outstanding, without any further vote or action by the stockholders.

Our Board of Directors may authorize the issuance of preferred stock with voting or conversion rights that could harm the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, or preventing a change in control of our company and might harm the market price of our common stock and the voting power and other rights of the holders of our common stock. As of the end of fiscal 2020, there were no shares of preferred stock outstanding.

Shares Reserved for Future Issuance

Shares of common stock reserved for future issuance as of the end of fiscal 2020 were as follows:

Stock options outstanding			329,786
Restricted stock units outstanding			1,360,324
Market stock units outstanding			391,532
Performance stock units outstanding			333,848
Awards available for grant under all share-based compensation plans			3,190,152
Reserved for future issuance			5,605,642

Treasury Stock

Our cumulative authorization of repurchases under our common stock repurchase program as of the end of fiscal 2020 was $1.4 billion, which is set to expire in July 2021. The program authorizes us to repurchase our common stock in the open market or in privately negotiated transactions depending upon market conditions and other factors. The number of shares repurchased and the timing of repurchases is based on the level of our cash balances, general business and market conditions, and other factors, including alternative investment opportunities. Common stock repurchased under this program is held as treasury stock. As of the end of fiscal 2020, we had $177.4 million of common stock remaining to be repurchased under our common stock repurchase program.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Share-Based Compensation

9.	Share-Based Compensation

The purpose of our various share-based compensation plans is to attract, motivate, retain, and reward high-quality employees, directors, and consultants by enabling such persons to acquire or increase their proprietary interest in our common stock in order to strengthen the mutuality of interests between such persons and our stockholders and to provide such persons with annual and long-term performance incentives to focus their best efforts on the creation of stockholder value. Consequently, we determine whether to grant share-based compensatory awards subsequent to the initial award for our employees and consultants primarily on individual performance.

New Share-Based Compensation Plans

On October 29, 2019, our stockholders approved: (i) our 2019 Equity and Incentive Compensation Plan, or the 2019 Incentive Plan, to replace our Amended and Restated 2010 Incentive Compensation Plan, or the 2010 Incentive Plan, and (ii) our 2019 Employee Stock Purchase Plan, or the 2019 ESPP, to replace our Amended and Restated 2010 Employee Stock Purchase Plan, or our 2010 ESPP. Upon approval of the 2019 Incentive Plan, new awards are no longer issued under the 2010 Incentive Plan. Awards outstanding at October 29, 2019 under our prior share-based compensation plans were not impacted by the approval of the 2019 Incentive Plan and continue to remain outstanding and vest by their terms under the applicable share-based compensation plan.

The 2019 Incentive Plan authorizes our Board of Directors to provide equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, cash incentive awards, performance shares, performance stock units, and other stock-based awards. The number of shares approved by stockholders under the 2019 Incentive Plan was 1,230,000. The 2019 ESPP authorizes the Company to provide eligible employees with an opportunity to acquire an equity interest in the Company through the purchase of stock at a discount, with an initial authorization of 1,500,000 shares.

Effective August 19, 2019, we adopted the 2019 Inducement Equity Plan. 650,000 shares of our common stock have been reserved for issuance under the 2019 Inducement Equity Plan, subject to adjustment for stock dividends, stock splits, or other changes in our common stock or capital structure. The 2019 Inducement Equity Plan is intended to comply with Rule 5635(c)(4) of the Nasdaq Stock Market Listing Rules, which provide an exception to the Nasdaq Stock Market Listing Rules’ on the shareholder approval requirement for the issuance of securities with regards to grants to employees of the Company or its subsidiaries as an inducement material to such individuals entering into employment with the Company or its subsidiaries. An individual is eligible to receive an award under the 2019 Inducement Equity Plan only if he or she was not previously an employee or director of our Company (or is returning to work after a bona-fide period of non-employment), and an award under the 2019 Inducement Equity Plan is a material inducement for him or her to accept employment with our Company.

Our share-based compensation plans with outstanding awards consist of our 2010 Incentive Plan, our 2019 Incentive Plan, our 2019 Inducement Equity Plan, and our 2019 ESPP.

Share-based compensation awards available for grant or issuance for each plan as of the beginning of the fiscal year, including changes in the balance of awards available for grant for fiscal 2020, were as follows:

	Awards						2019			2019						2010

Share-based compensation and the related tax benefit recognized in our consolidated statements of income for fiscal 2020, 2019, and 2018 were as follows (in millions):

	2020		2019		2018
Cost of revenue	$	2.1	$	3.1	$	3.2
Research and development		32.3		33.7		38.6
Selling, general, and administrative		26.0		22.2		29.5
Total	$	60.4	$	59.0	$	71.3
Income tax benefit on share-based compensation	$	6.3	$	4.3	$	11.1

Included in the preceding table is share-based compensation for our cash-settled phantom stock units, which we granted in October 2019 (see Phantom Stock Units below) (in millions):

	2020
Cost of revenue	$	0.2
Research and development		9.1
Selling, general, and administrative		1.8
Total	$	11.1

We recognize a tax benefit upon expensing certain share-based awards associated with our share-based compensation plans, including nonqualified stock options, RSUs, market stock units, or MSUs, and PSUs, but we cannot recognize a tax benefit concurrent with the recognition of share-based compensation expenses associated with incentive stock options and employee stock purchase plan shares (qualified stock awards). For qualified stock awards we recognize a tax benefit only in the period when disqualifying dispositions of the underlying stock occur, which historically has been up to several years after vesting and in a period when our stock price substantially increases.

We determine excess tax benefit using the long-haul method in which we compare the actual tax benefit associated with the tax deduction from share-based award activity to the hypothetical tax benefit based on the grant date fair values of the corresponding share-based awards. Tax benefit associated with excess tax deduction creditable to income tax provision is recognized when incurred. Tax deficiency associated with a tax shortfall is debited to income tax provision when incurred.

Historically, we have issued new shares in connection with our share-based compensation plans, however, treasury shares are also available for issuance. Any additional shares repurchased under our common stock repurchase program will be available for issuance under our share-based compensation plans.

Stock Options

Our share-based compensation plans with outstanding stock option awards include our 2010 Incentive Plan. Under our 2010 Incentive Plan, we were able to grant incentive stock options or nonqualified stock options to purchase shares of our common stock at not less than 100% of the fair market value, or FMV, on the date of grant. Option granting ceased in fiscal 2018.

Options granted under our 2010 Incentive Plan generally vest three to four years from the vesting commencement date and expire seven years after the date of grant if not exercised.

Certain stock option activity for fiscal 2020 and balances as of the end of fiscal 2020 were as follows:

	Stock			Weighted
	Option			Average		Intrinsic
	Awards			Exercise		Value
	Outstanding			Price		(In millions)
Balance at June 2019		1,191,929		$	59.07
Exercised		(542,776	)		44.03
Forfeited		(8,117	)		50.70
Expired		(311,250	)		74.16
Balance at June 2020		329,786			69.78	$	0.4
Exercisable at June 2020		329,057			69.83	$	0.4

The aggregate intrinsic value was determined using the closing price of our common stock on the last trading day of fiscal 2020, or June 26, 2020, of $56.26 and excludes the impact of options that were not in-the-money. Approximately 23% of the stock option awards outstanding were vested and in-the-money as of the end of fiscal 2020.

At the end of fiscal 2020, we estimated that we have 0.3 million fully vested options with an aggregate intrinsic value of $0.4 million, having a weighted average exercise price of $69.83 and a weighted average remaining contractual term of 1.7 years.

Cash received and the aggregate intrinsic value of stock options exercised for fiscal 2020, 2019, and 2018 were as follows (in millions):

	2020		2019		2018
Cash received	$	23.9	$	5.2	$	16.7
Aggregate intrinsic value	$	10.8	$	2.4	$	15.2

There were no stock options granted in fiscal 2020 or 2019. The fair value of each award granted under our share-based compensation plans for fiscal 2018 was estimated at the date of grant using the Black-Scholes option pricing model, assuming no expected dividends and the following range of assumptions:

	2018
Expected volatility	46.2%
Expected life in years	4.4
Risk-free interest rate	1.8%
Fair value per award	$	18.04

The unrecognized share-based compensation costs for stock options granted under our various plans was less than $0.1 million as of the end of fiscal 2020, to be recognized over a weighted average period of approximately 0.11 years.

Restricted Stock Units

Our 2019 Incentive Plan and our 2019 Inducement Equity Plan provide for the grant of RSUs to our employees, consultants, and directors, and previously our 2010 Incentive Plan provided for the grant of deferred stock units, or DSUs, to our employees, consultants, and directors. An RSU and a DSU are each a promise to deliver shares of our common stock at a future date in accordance with the terms of the grant agreement and the words can be used interchangeably. We began granting DSUs in January 2006 and RSUs in 2019. The use of RSUs will cover the meaning of both RSUs and DSUs.

RSUs granted generally vest ratably over three to four years from the vesting commencement date. Delivery of shares under the plans take place on the quarterly vesting dates. At the delivery date, we withhold shares to cover applicable statutory minimum tax withholding for grantees subject to withholding and deliver a net quantity of shares to the grantee after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the RSU award.

RSU activity, including RSUs granted, delivered, and forfeited in fiscal 2020, and the balance and aggregate intrinsic value of RSUs as of the end of fiscal 2020 was as follows:

				Aggregate		Weighted
				Intrinsic		Average
	RSU Awards			Value		Grant Date
	Outstanding			(in millions)		Fair Value
Balance at June 2019		1,878,853				$	40.90
Granted		742,586					46.26
Delivered		(845,550	)				43.75
Forfeited		(415,565	)				39.77
Balance at June 2020		1,360,324		$	76.5		42.40

Of the shares delivered, 200,587 shares valued at $8.4 million were withheld to meet statutory tax withholding requirements. The aggregate intrinsic value was determined using the closing price of our common stock on the last trading day of fiscal 2020, or June 26, 2020, of $56.26.

The unrecognized share-based compensation cost for RSUs granted under our 2019 Incentive Plan, our 2019 Inducement Equity Plan and our 2010 Incentive Plan was approximately $41.5 million as of the end of fiscal 2020, which will be recognized over a weighted average period of approximately 2.04 years. The aggregate market value of RSUs delivered in fiscal 2020, 2019, and 2018 was $36.0 million, $35.7 million, and $21.4 million, respectively.

Market Stock Units

Our 2019 Incentive Plan and our 2019 Inducement Equity Plan provide for the grant of MSU awards, to our employees, consultants, and directors. An MSU is a promise to deliver shares of our common stock at a future date based on the achievement of market-based performance requirements in accordance with the terms of the MSU grant agreement.

We have granted MSUs to our executive officers and other management members, which are designed to vest in three tranches with the target quantity for each tranche equal to one-third of the total MSU grant. The first tranche vests based on a one-year performance period; the second tranche vests based on a two-year performance period; and the third tranche vests based on a three-year performance period. Performance is measured based on the achievement of a specified level of total stockholder return, or TSR, relative to the TSR of the S&P Semiconductor Select Industry Index, or Index, for grants made beginning in fiscal 2018. The potential payout ranges from 0% to 200% of the grant target quantity and is adjusted on a two-to-one ratio based on our TSR performance relative to the Index TSR using the following formula:

(100% + ([Synaptics TSR—{Index TSR}] x 2))

The payout for tranche one and two will not exceed 100% and the payout for tranche three will be calculated based on the total target quantity for the entire grant multiplied by the payout factor, based on performance for the three-year performance period, less shares issued for the first tranche and the second tranche. In the event the performance for the three-year performance period results in a payout that is less than the combined payout of tranche one and two, we do not claw-back shares delivered in the earlier performance periods.

Delivery of shares earned, if any, will take place on the dates provided in the applicable MSU grant agreement, assuming the grantee is still an employee, consultant, or director of our company at the end of the applicable performance period. On the delivery date, we withhold shares to cover applicable statutory tax withholding for grantees subject to withholding and deliver a net quantity of shares to the grantee after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the MSU award.

MSU activity, including MSUs granted, delivered, and forfeited in fiscal 2020, and the balance and aggregate intrinsic value of MSUs as of the end of fiscal 2020 were as follows:

				Aggregate		Weighted
				Intrinsic		Average
	MSU Awards			Value		Grant Date
	Outstanding			(in millions)		Fair Value
Balance at June 2019		210,732				$	52.15
Granted		359,336					57.51
Performance adjustment		(58,707	)				—
Delivered		(23,018	)				52.39
Forfeited		(96,811	)				52.46
Balance at June 2020		391,532		$	22.0		56.93

As a result of the Synaptics TSR underperforming the SOX Index TSR by 136 percentage points for the payout period ended in fiscal 2020, we did not deliver any of the targeted shares underlying the fiscal 2017 MSU grants. As a result of the Synaptics TSR underperforming the Index TSR by 34.2 percentage points for the payout period ended in fiscal 2020, we delivered 31.6% of the targeted shares underlying the fiscal 2018 MSU grants. As a result of the Synaptics TSR underperforming the Index TSR by 34.3 percentage points for the payout period ended in fiscal 2020, we delivered 31.5% of the targeted shares underlying the fiscal 2019 MSU grants.

Of the shares delivered, 8,706 shares valued at $0.4 million were withheld to meet statutory minimum tax withholding requirements. The aggregate intrinsic value assumes a 100% payout factor and was determined using the closing price of our common stock on the last trading day of fiscal 2020, or June 26, 2020, of $56.26.

The fair value of each MSU granted from our plans for fiscal 2020, 2019, and 2018 was estimated at the date of grant using the Monte Carlo simulation model, assuming no expected dividends and the following assumptions:

	2020	2019			2018
Expected volatility of company	45.46% - 52.55%		50.58	%	49.16% - 50.60%
Expected volatility of Index	24.64% - 33.44%		23.40	%	22.37% - 22.52%
Correlation coefficient	0.53 - 0.58		0.51		0.52 - 0.53
Expected life in years	2.50 - 4.00		2.88		2.80 - 2.92
Risk-free interest rate	0.26% - 1.52%		2.92	%	1.72% - 1.88%
Fair value per award	$55.52 - $100.38	$27.70 - $85.52			$48.22 - $59.19

We amortize the compensation expense over the three-year performance and service period. The unrecognized share-based compensation cost of our outstanding MSUs was approximately $16.6 million as of the end of fiscal 2020, which will be recognized over a weighted average period of approximately 1.35 years.

Performance Stock Units

Our 2019 Incentive Plan and our 2010 Incentive Plan provide for the grant of PSU awards to our employees, consultants, and directors. A PSU is a promise to deliver shares of our common stock at a future date based on the achievement of performance-based requirements in accordance with the terms of the PSU grant agreement.

We have granted PSUs to our executive officers and other management members, which are designed to vest in three tranches with the target quantity for each tranche equal to one-third of the total PSU grant. The grants have a specific one-year performance period and vesting occurs over three service periods with the final service period ending approximately three years from the grant date. Performance is measured based on the achievement of a specified level of non-GAAP earnings per share. The potential payout ranges from 0% to 200% of the grant target quantity and is adjusted on a linear basis with a payout triggering if our non-GAAP earnings per share equals greater than 65% of the target with a maximum payout achieved at 135% of target.

Delivery of shares earned, if any, will take place on the dates provided in the applicable PSU grant agreement, assuming the grantee is still an employee, consultant, or director of our company at the end of the applicable service period. On the delivery date, we withhold shares to cover applicable statutory tax withholding for grantees subject to withholding and deliver a net quantity of shares to the grantee after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the PSU award.

During the fiscal year ended June 27, 2020, PSU activity, including PSUs granted, delivered, and forfeited, and the balance and aggregate intrinsic value of PSUs as of June 27, 2020 was as follows:

				Aggregate		Weighted
				Intrinsic		Average
	PSU Awards			Value		Grant Date
	Outstanding			(in millions)		Fair Value
Balance at June 2019		192,618				$	38.35
Granted		335,966					41.90
Performance adjustment		604					—
Delivered		(61,668	)				39.63
Forfeited		(133,672	)				38.56
Balance at June 2020		333,848		$	18.8		41.61

We value PSUs using the aggregate intrinsic value on the date of grant and amortize the compensation expense over the three-year service period on a ratable basis, dependent upon the probability of meeting the performance measures. Of the shares delivered, 22,521 shares valued at $0.9 million were withheld to meet statutory minimum tax withholding requirements. The unrecognized share-based compensation cost of our outstanding PSUs was approximately $14.6 million as of June 27, 2020, which will be recognized over a weighted average period of approximately 1.22 years.

Phantom Stock Units

The 2019 Incentive Plan authorizes the grant of phantom stock units to non-employee directors, officers and employees. We initially granted phantom stock units in October 2019. Phantom stock units are cash-settled and entitle the recipient to receive a cash payment equal to the value of a single share for each unit based on the average closing share price of our stock over the thirty calendar days prior to the vesting date. Grants of phantom stock units vest over three years, with an annual vesting date of October 31 each year subsequent to the grant date. We recognize compensation expense for phantom stock units on a straight-line basis for each tranche of each award based on the average closing price of our common stock over the thirty calendar days ended prior to each balance sheet date. The outstanding phantom stock units had a fair value of $64.18 per unit at June 27, 2020 and our accrued liability for such units was $11.1 million.

Phantom stock activity was as follows:

				Aggregate
	Phantom			Intrinsic
	Stock Units			Value
	Outstanding			(in millions)
Granted		953,305
Forfeited		(164,192	)
Balance as of June 2020		789,113		$	44.4

Employee Stock Purchase Plan

Our 2019 ESPP became effective October 29, 2019 which replaced our 2010 ESPP. The 2019 ESPP, and previously the 2010 ESPP, allows employees to designate up to 15% of their base compensation, subject to legal restrictions and limitations, to purchase shares of common stock at 85% of the lesser of the FMV at the beginning of the offering period or the exercise date. Under the 2019 ESPP, the offering period extends for up to one year and includes two exercise dates occurring at six-month intervals. Under the 2010 ESPP, the offering period extended for up to two years and included four exercise dates occurring at six-month intervals. Under the terms of our 2019 ESPP, and previously under our 2010 ESPP, if the FMV at an exercise date is less than the FMV at the beginning of the offering period, the current offering period will terminate and a new offering period will commence.

Shares purchased, weighted average purchase price, cash received, and the aggregate intrinsic value for employee stock purchase plan purchases in fiscal 2020, 2019, and 2018 were as follows (in millions, except shares purchased and weighted average purchase price):

	2020		2019		2018
Shares purchased		346,502		544,886		486,263
Weighted average purchase price	$	30.50	$	29.48	$	32.07
Cash received	$	10.6	$	16.1	$	15.6
Aggregate intrinsic value	$	10.1	$	2.8	$	3.9

The fair value of each award granted under our 2019 ESPP and our 2010 ESPP for fiscal 2020, 2019, and 2018 was estimated using the Black-Scholes option pricing model, assuming no expected dividends and the following range of assumptions:

	2020		2019		2018
Expected volatility	43.8%-45.4%		43.8%-44.2%		43.7% - 49.8%
Expected life in years	0.25 - .75		0.5 - 1.5		0.5 - 2.0
Risk-free interest rate	1.62% - 2.43%		2.43%-2.68%		1.42% - 2.45%
Fair value per award	$	15.48	$	15.63	$	13.54

The expected volatility is based on either implied volatility for the expected lives of 0.5 years or a weighting of implied and historical volatility for expected lives greater than 0.5 years. The expected life is the period starting at the enrollment date until each purchase date remaining in the offering period at the date of enrollment in the plan. The risk-free interest rate is based on U.S. Treasury yields or yield curve in effect for each expected life.

Unrecognized share-based compensation costs for awards granted under our 2019 ESPP at the end of fiscal 2020 were approximately $0.6 million that will be amortized over the next 2 months.

Income Taxes

11.	Income Taxes

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security, or CARES, Act was enacted and signed into law. The CARES Act did not have a material impact on the income tax provision for the fiscal year ended June 27, 2020.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation, commonly known as the Tax Cuts and Jobs Act of 2017, or the Act, which significantly revised the Internal Revenue Code of 1986, as amended. The Act contains broad and complex changes to corporate taxation, including, in part, reduction of the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously considered indefinitely reinvested overseas, and creates new taxes on certain foreign sourced earnings. As our accounting and tax year is the fiscal period ending on the last Saturday in June, U.S. federal tax law requires that taxpayers with a fiscal year that spans the effective date of a rate change to calculate a blended tax rate based on the pro rata number of days in the fiscal year before and after the effective date. As a result, our U.S. federal tax rate for fiscal 2018 was a days-weighted blended tax rate of 28.17%. For fiscal 2019 and subsequent tax years, including fiscal 2020, our U.S. federal tax rate is 21%.

Staff Accounting Bulletin 118 allows companies to record provisional amounts and recognize the effect of the tax law during a measurement period. The measurement period ended in the second quarter of our fiscal 2019. As of June 29, 2019, we finalized our accounting for the tax impact of the Act. However, further technical guidance related to the Act, including final regulations on a broad range of topics, is expected to be issued and, as such, if our interpretation and final accounting are inconsistent with future regulations and guidance, we will recognize the impact as a discrete item in the period such guidance is issued.

The Global Intangible Low-Tax Income, or GILTI, which is a provision under the Act, imposes a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. GILTI requires an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred, or (2) factoring such amounts into the measurement of deferred taxes. We elected to treat GILTI as a period cost and recognize the impact in the period when it is incurred.

Net deferred tax assets of $28.7 million and $31.1 million were non-current as of the end of fiscal 2020 and 2019, respectively, and were included in other assets in the accompanying consolidated balance sheets.

Significant components of our deferred tax assets (liabilities) as of the end of fiscal 2020 and 2019 consisted of the following (in millions):

Realization of deferred tax assets depends on our generating sufficient U.S. and certain foreign taxable income in future years to obtain a benefit from the utilization of those deferred tax assets on our tax returns. Accordingly, the amount of deferred tax assets considered realizable may increase or decrease when we reevaluate the underlying basis for our estimates of future U.S. and foreign taxable income. As of the end of fiscal 2020, a valuation allowance of $33.3 million was maintained to reduce deferred tax assets to levels we believe are more likely than not to be realized through future taxable income. The net change in the valuation allowance during fiscal 2020 was an increase of $2.9 million.

Undistributed earnings of our foreign subsidiaries were approximately $1.0 billion as of the end of fiscal 2020 and are considered to be indefinitely reinvested overseas.

As of the end of fiscal 2020, we had federal and California net operating loss carryforwards of approximately $1.5 million and $46.2 million, respectively. The California net operating loss will begin to expire in fiscal 2021, if not utilized. Under current tax law, net operating loss and tax credit carryforwards available to offset future income or income taxes may be limited by statute or upon the occurrence of certain events, including significant changes in ownership.

We had $14.0 million and $38.5 million of federal and state research tax credit carryforwards, respectively, as of the end of fiscal 2020. The federal research tax credit carryforward will begin to expire in 2026 and the state research tax credit can be carried forward indefinitely.

The total liability for gross unrecognized tax benefits related to uncertain tax positions, included in other liabilities in our consolidated balance sheets, increased by $1.2 million from $18.9 million in fiscal 2019 to $20.1 million in fiscal 2020. Of this amount, $12.6 million will reduce the effective tax rate on income from continuing operations, if recognized. A reconciliation of the beginning and ending balance of gross unrecognized tax benefits for fiscal 2020, 2019, and 2018 consisted of the following (in millions):

	2020			2019			2018
Beginning balance	$	18.9		$	24.8		$	15.2
Increase in unrecognized tax benefits related to current year tax positions		3.2			4.2			10.5
Increase in unrecognized tax benefits related to prior year tax positions		0.1			—			—
Decrease due to effective settlement with tax authorities		—			(6.2	)		—
Remeasurement of unrecognized tax benefits		—			(2.0	)		—
Decrease due to statute expiration		(2.1	)		(1.9	)		(0.9	)
Ending Balance	$	20.1		$	18.9		$	24.8

Accrued interest and penalties remained flat in fiscal 2020 and 2019 and increased by $0.7 million representing income tax expense in fiscal 2018 as compared to fiscal 2017. Accrued interest and penalties were $1.9 million as of June 27, 2020 and June 29, 2019. Our policy is to classify interest and penalties, if any, as components of income tax expense.

It is reasonably possible that the amount of liability for unrecognized tax benefits may change within the next 12 months; an estimate of the range of possible changes could result in a decrease of $1.7 million to an increase of $2.3 million.

In February 2020, Altera Corporation filed a petition for a writ of certiorari asking the Supreme Court to review the Ninth Circuit Court of Appeals’ decision that reversed the 2015 decision of the U.S. Tax Court in Altera Corp. v. Commissioner, which found that Treasury regulations addressing the treatment of stock-based compensation in a cost sharing agreement with a related party were invalid. In June 2020, the U.S. Supreme Court declined the writ of certiorari in the case of Altera Corp vs Commissioner. As our tax filing position and consolidated financials are consistent with the treasury regulations and the findings of the Ninth Circuit Court of Appeals decision, no adjustment to our financial statements is required.

Our major tax jurisdictions are the United States, Hong Kong SAR, and Japan. From fiscal 2014 onward, we remain subject to examination by one or more of these jurisdictions. In August 2018, we received the revenue agent’s report resolving the fiscal 2014 and fiscal 2015 examination by the Internal Revenue Service with no material impact on our consolidated financial statements. Our case was reviewed by the Joint Committee on Taxation, which concluded in September 2019 with no further impact to our consolidated financial statements. Any prospective adjustments to our

unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to our effective tax rate. Accordingly, our effective tax rate could fluctuate materially from period to period.

Restructuring Activities

13.	Restructuring Activities

During fiscal 2020 we initiated restructuring activities, some of which included severance costs which were for activities intended to further improve efficiencies in our operational activities to align our cost structure consistent with our revenue levels and one was severance costs related to employees who transitioned with the sale of our assets of our TDDI product line for LCD mobile displays (See Note 4. Divestiture included in the consolidated financial statements contained elsewhere in this Report). The restructuring costs related to these activities were recorded to the restructuring costs line item within our consolidated statements of operation. Some of the activities relating to these restructurings are complete as of June 27, 2020. The remaining activities are expected to be complete in the third quarter of fiscal 2021.

The restructuring liability activity for these restructuring activities during fiscal 2020 was as follows (in millions):

	Employee Severance
	and Benefits

Cash payments		(19.0	)
Balance as of June 2020	$	6.1

In August 2018, we committed to and initiated a restructuring of our mobile fingerprint optical business. The costs for this restructuring activity primarily related to severance costs for a reduction in headcount and related costs. These activities were complete as of June 29, 2019. In June 2019, we committed to and initiated a restructuring action intended to reduce our operating cost structure further. The costs for this restructuring action primarily related to severance costs for a reduction in headcount. Restructuring costs related to these fiscal 2019 restructuring activities were recorded to the restructuring costs line item within our consolidated statements of operations. The activities relating to the June 2019 restructuring action are complete as of June 27, 2020.

In November 2017, we committed to and initiated a restructuring action intended to streamline and reduce our operating cost structure and capitalize on acquisition synergies. The costs relating to this restructuring primarily related to severance costs for a reduction in headcount, facility consolidation and related costs. In April 2018, we committed to and initiated a restructuring to close a research and development facility. The costs relating to this restructuring include employee severance and related benefits and facility closure charges. Restructuring costs related to both the November 2017 and April 2018 restructuring activities were recorded to the restructuring costs line item within our consolidated statements of operations and were complete as of June 30, 2018.

Acquisitions

On July 2, 2020, we entered into definitive agreements with Broadcom to acquire certain assets and assume certain liabilities of, and obtain non-exclusive licenses relating to, Broadcom’s existing Wi-Fi, Bluetooth and GPS/GNSS products and business in the IoT market, for aggregate consideration of $250 million in cash which closed on July 23, 2020. We also entered into certain transition agreements with Broadcom for a period of three years. We acquired these assets and assumed certain liabilities from Broadcom in order to obtain wireless connectivity technology which will enhance our current IoT business. This acquisition will be accounted for using the purchase method of accounting in accordance with the business acquisition guidance.

On July 17, 2020, we entered into a definitive agreement to acquire DisplayLink Corporation, a leader in high-performance video compression technology, for $305 million in cash. The acquisition closed on July 31, 2020. The intent of this acquisition is to obtain performance video compression technology which will further enhance our current IoT business. This acquisition will be accounted for using the purchase method of accounting in accordance with the business acquisition guidance.

Export Administration Regulation

On August 17, 2020, the Bureau of Industry and Security of the U.S. Department of Commerce issued final rules that further restrict access by Huawei Technologies (Huawei) and its non-U.S. affiliates on the Entity List to items produced domestically and abroad from U.S. technology and software. The final rules may prevent us from selling products to Huawei entities without a license issued subject to the Export Administration Regulation (EAR). We anticipate applying for an EAR export license, but it is unclear if an EAR export license will be granted. Further, even if we are unaffected by the rule or are able to obtain an export license, Huawei may not be able to source other components from U.S. suppliers, which could indirectly negatively impact Huawei’s demand for our products. At this time, we believe the new rules will not materially impact revenue in our September 2020 quarter, while the longer-term revenue impact remains unclear. During our most recently completed fiscal quarter, June 2020, our direct and indirect sales to Huawei represented less than 10% of our revenue. See Item 1A. Risk Factors for further discussion of the potential for changes to import, export and economic sanction laws that may adversely affect our operating results.
