Special Note Regarding Forward-Looking and Cautionary Statements

This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, as amended, based on our current expectations, estimates and projections about our operations, industry, financial condition, performance, results of operations, and liquidity. Forward-looking statements are statements other than historical information or statements of current condition and relate to matters such as future financial performance, future operational performance, the anticipated impact of specific items on future earnings, and our plans, objectives and expectations. Statements containing words such as "may," "believe," "anticipate," "expect," "intend," "plan," "project," "estimate," "should," "will," "designed to," "projections," or "business outlook," or other similar expressions constitute forward-looking statements. Forward-looking statements involve known and unknown risks and uncertainties that could cause actual results and events to differ materially from those projected.

Potential factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to:

• fluctuation in the Company’s future results;

• downturns in the business cycle;

• rapid decline in the average selling price;

• reduced demand for the Company’s products, including due to global economic conditions and potential changes in economic policy;

• business interruptions;

• the Company’s reliance on a limited number of suppliers and subcontractors for components and materials;

• potentially insufficient liability insurance if the Company’s products are found to be defective;

• obsolete inventories as a result of changes in demand and change in life cycles for the Company’s products;

• the Company’s inability to successfully develop and sell new products;

• lengthy and expensive product qualification processes without any assurance of product sales;

• the Company’s products failing to meet industry standards;

• the Company’s inability to protect intellectual property rights;

• the Company suffering losses if its products infringe the intellectual property rights of others;

• the Company’s need to commit resources to product production prior to receipt of purchase commitments;

• increased business risk resulting from significant business with foreign customers;

• the Company’s foreign currency exposures;

• potential increased tax liabilities and effective tax rate if the Company needs to repatriate funds held by foreign subsidiaries;

• export restrictions and laws affecting the Company’s trade and investments including the adoption and expansion of trade restrictions or the occurrence of trade wars;

• the impact of tariffs on the Company's expenses and on the pricing and demand for the Company's customer's products;

• the Company's inability to adequately compete against larger, more established entities;

• increased competition due to industry consolidation;

• the loss of any one of the Company’s significant customers;

• volatility of customer demand;

• termination of a contract by a distributor;

• sales of our products on the gray market;

3

• the Company’s failure to maintain effective internal control over financial reporting and disclosure controls and procedures;

• government regulations and other standards, including those that impose operational and reporting requirements;

• the Company’s failure to comply with applicable environmental regulations;

• compliance with conflict minerals regulations;

• increase in the Company’s cost of doing business as a result of having to comply with the codes of conduct of certain of the Company’s customers and suppliers;

• changes in tax law, including effective tax rates, and review by taxing authorities;

• taxation of Company sales in non-U.S. jurisdictions;

• the Company’s limited experience with government contracting;

• potential government investigations and inquiries;

• loss of the Company’s key personnel;

• risks associated with companies the Company has acquired in the past and may acquire in the future and the Company’s ability to successfully integrate acquired businesses and benefit from expected synergies;

• the Company may be required to recognize additional impairment charges;

• loss of value of investments in entities not under our control;

• the Company may not receive accurate, complete or timely financial information from entities for which the Company is required to consolidate such information;

• the Company may be adversely affected by new accounting pronouncements;

• the Company’s ability to generate cash to service its debt obligations;

• restrictive covenants in the Company’s credit agreement which may restrict its ability to pursue its business strategies;

• the Company’s reliance on certain critical information systems for the operation of its business;

• costs associated with the Company’s indemnification of certain customers, distributors and other parties;

• the Company’s share price could be subject to extreme price fluctuations;

• the impact on the Company’s common stock price if securities or industry analysts do not publish reports about the Company’s business or adversely change their recommendations regarding the Company’s common stock;

• anti-takeover provisions in the Company’s organizational documents could make an acquisition of the Company more difficult; and

• the Company is subject to litigation risks which may be costly to defend

Additionally, forward-looking statements should be considered in conjunction with the cautionary statements contained in this Quarterly Report on Form 10-Q, including, without limitation, information under the captions "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" and additional factors that accompany the related forward-looking statements in this Quarterly Report on Form 10-Q, in our Annual Report on Form 10-K for the fiscal year ended January 28, 2018 including, without limitation information under the caption "Risk Factors", in other filings with the Securities and Exchange Commission ("SEC"), and in material incorporated herein and therein by reference. In light of the significant risks and uncertainties inherent in the forward-looking information included herein that may cause actual performance and results to differ materially from those predicted, any such forward-looking information should not be regarded as representations or guarantees by the Company of future performance or results, or that its objectives or plans will be achieved, or that any of its operating expectations or financial forecasts will be realized. Reported results should not be considered an indication of future performance. Investors are cautioned not to place undue reliance on any forward-looking information contained herein, which reflect management’s analysis only as of the date hereof. Except as required by law, the Company assumes no obligation to publicly release the results of any update or revision to any forward-looking statement that may be made to reflect new information, events or circumstances after the date hereof or to reflect the occurrence of unanticipated or future events, or otherwise.

In addition to regarding forward-looking statements with caution, you should consider that the preparation of the consolidated financial statements requires us to draw conclusions and make interpretations, judgments, assumptions and estimates with respect to certain factual, legal, and accounting matters. Our financial statements might have been materially impacted if we had reached different conclusions or made different interpretations, judgments, assumptions or estimates.

SEMTECH CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1: Organization and Basis of Presentation

Nature of Business

Semtech Corporation (together with its consolidated subsidiaries, the "Company" or "Semtech") is a global supplier of analog and mixed-signal semiconductors and advanced algorithms. The end customers for the Company’s products are primarily original equipment manufacturers ("OEMs") that produce and sell electronics.

The Company designs, develops and markets a wide range of products for commercial applications, the majority of which are sold into the enterprise computing, communications, high-end consumer and industrial end-markets.

Enterprise Computing: datacenters, passive optical networks, desktops, notebooks, servers, monitors, printers and other computer peripherals.

Communications: base stations, optical networks, carrier networks, switches and routers, cable modems, wireless LAN and other communication infrastructure equipment.

High-End Consumer: handheld products, smartphones, wireless charging, set-top boxes, digital televisions, monitors and displays, tablets, wearables, digital video recorders and other consumer equipment.

Industrial: analog and digital video broadcast equipment, Video-over-IP solutions, automated meter reading, Internet of Things ("IoT"), smart grid, wireless charging, military and aerospace, medical, security systems, automotive, industrial and home automation and other industrial equipment.

Fiscal Year

The Company reports results on the basis of 52 and 53 week periods and ends its fiscal year on the last Sunday in January. The other quarters generally end on the last Sunday of April, July and October. All quarters consist of 13 weeks except for one 14-week period in the fourth quarter of 53-week years. The second quarter of fiscal years 2019 and 2018 each consisted of 13 weeks.

Principles of Consolidation

The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company, in accordance with accounting principles generally accepted in the United States ("GAAP") and on the same basis as the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended January 28, 2018. In the opinion of the Company, these interim unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, the financial position of the Company for the interim periods presented. All intercompany balances have been eliminated. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the interim unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete set of consolidated financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended January 28, 2018. The results reported in these interim unaudited condensed consolidated financial statements should not be regarded as indicative of results that may be expected for any subsequent period or for the entire year.

The Company’s interim unaudited condensed consolidated statements of income are referred to herein as the "Statements of Income." The Company’s interim unaudited condensed consolidated balance sheets are referred to herein as the "Balance Sheets" and interim unaudited condensed consolidated statements of cash flows as the "Statements of Cash Flows."

Segment Information

The Company’s Chief Executive Officer ("CEO") has been identified as the Chief Operating Decision Maker ("CODM") as defined by guidance regarding segment disclosures (see Note 12 for further discussion). Prior to the first quarter of fiscal year 2019, the Company had four operating segments. Beginning with the first quarter of fiscal year 2019, the Company identified three operating segments that aggregate into one reportable segment, the Semiconductor Products Group.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates.

Acquisitions

On May 2, 2018, the Company acquired substantially all the assets of IC Interconnect, Inc. (“ICI”) for a cash payment of approximately $7.3 million. The addition of ICI is aimed at further enhancing the Company’s U.S. research and development capabilities for its next-generation Z-Pak platform. $4.8 million was attributed to goodwill and $2.5 million was attributed to the estimated fair values of the tangible net assets acquired. The goodwill is deductible for tax purposes. The transaction was accounted for as a business combination and we are still assessing the purchase price allocation.

Net revenues, earnings and pro forma results of operations have not been presented because they are not material to the Company’s consolidated financial statements.

Settlements

On August 1, 2018, the Company announced the settlement of a lawsuit filed against HiLight Semiconductor Limited and related individual Defendants in accordance with which Semtech is to be paid approximately $9.0 million to cover damages for claims, costs and attorneys' fees. The $6.6 million received during the second quarter of fiscal year 2019 is presented within selling, general and administrative ("SG&A").

Recent Accounting Standards Adopted

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification ("ASC") 606), which requires an entity to recognize revenue from the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance addresses, in particular, contracts with more than one performance obligation, as well as the accounting for some costs to obtain or fulfill a contract with a customer, and provides for additional disclosures with respect to revenues and cash flows arising from contracts with customers.

The Company adopted the standard, effective January 29, 2018, using the modified retrospective transition method which resulted in an adjustment to retained earnings for the cumulative effect of applying the standard to all contracts not completed as of the adoption date. The primary change associated with the adoption relates to the Company’s sales to distributors with return or price adjustment rights where the Company will no longer defer revenue until the resale by the distributor to the end customer, but rather, will record revenue at the time control transfers to the distributor. The Company estimated the effects of returns and allowances provided to these distributors. Upon adoption, including the effect of income taxes, opening retained earnings as of January 29, 2018 increased by $11.1 million net, as a result of these changes. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Asset Transfers Other Than Inventory (Topic 740). This accounting standard update is aimed at recognizing the income tax consequences of intra-entity transfers of assets other than inventory when they occur. This removes the exception to postpone the recognition of income tax consequences of intra-entity transfers until the asset has been sold to an outside party. In the first quarter of 2019, the Company adopted ASU 2016-16 using a modified retrospective transition method, resulting in a $1.8 million decrease in retained earnings, a $3.7 million net increase in deferred income tax assets, and a $5.5 million decrease in pre-paid taxes.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The primary purpose of this ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic.

Accounting Guidance Issued but Not Adopted as of July 29, 2018

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require that substantially all leases be recognized by lessees on their balance sheets as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. Public entities are required to apply the amendments for annual periods beginning after December 15, 2018 and for interim periods within those annual periods. The Company will adopt this update beginning in the first quarter of fiscal year 2020 utilizing the modified retrospective transition method by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to elect certain practical expedients permitted under the transition guidance within the standard.

The Company expects the valuation of right of use assets and lease liabilities, previously described as operating leases, to be the present value of the Company’s forecasted future lease commitments. The Company is continuing to assess the overall impacts of the new standard, including the discount rate to be applied in these valuations, and expects the amendments will have a material impact on our consolidated financial statements, primarily to the consolidated balance sheets and related disclosures.

Note 2: Revenue

The Company derives its revenue primarily from the sale of semiconductor products into various end markets. Revenue is recognized when control of these products is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for these products. Control is generally transferred when products are shipped and, to a lesser extent, when the products are delivered. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed and are reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts. The Company includes revenue related to granted technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of its recurring ordinary business.

The Company determines revenue recognition through the following five steps:

• Identification of the contract, or contracts, with a customer

• Identification of the performance obligations in the contract

• Determination of the transaction price

• Allocation of the transaction price to the performance obligations in the contract

• Recognition of revenue when, or as, performance obligations are satisfied

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

The Company’s revenue contracts generally represent a single performance obligation to sell its products to trade customers. Net sales reflect the transaction prices for contracts, which include units shipped at selling prices reduced by variable consideration. Determination of variable consideration requires judgment by the Company. Variable consideration includes expected sales returns and other price adjustments. Variable consideration is estimated using the expected value method considering all reasonably available information, including the Company’s historical experience and its current expectations, and is reflected in the transaction price when sales are recorded. Sales returns are generally accepted at the Company’s discretion or from distributors with such rights. The Company’s contracts with trade customers do not have significant financing components or non-cash consideration. The Company records net sales excluding taxes collected on its sales to its trade customers.

The Company provides an assurance type warranty which is typically not sold separately and does not represent a separate performance obligation. The Company’s payment terms are generally aligned with shipping terms.

The following presents the amounts by which financial statement line items were affected in the current periods due to the adoption of ASC 606 as compared with the guidance that was in effect before the change:

	Three Months Ended		Six Months Ended
Statements of Income	July 29, 2018		July 29, 2018
(in thousands, except per share amounts)	Increase/(decrease)		Increase/(decrease)
Net sales	$	1,884	$	6,346
Cost of sales	$	428	$	1,444
Provision for taxes	$	306	$	1,030
Net income	$	1,150	$	3,873
Earnings per share:
Basic	0.02		0.06
Diluted	0.02		0.06

Balance Sheets	July 29, 2018
(in thousands)	Increase/(decrease)
Deferred revenue	(17,306	)

Excludes line items that were not materially affected by the Company's adoption of ASC 606. The adoption had no impact to total net cash provided by or used in operating, investing or financing activities in the Statements of Cash Flows.

Contract Modifications:

If a contract is modified, which does not normally occur, changes in contract specifications and requirements must be accounted for. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are to distributor agreements for adding new goods or services that are considered distinct from the existing contract and the change in contract price reflects the standalone selling price of the distinct service.

Disaggregated Revenue:

The Company disaggregates revenue from contracts with customers by types of products and geography, as it believes it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Refer to “Note 12: Segment Information” for further information on revenues by product line and geographic region.

Contract Balances:

Accounts receivable represents the Company’s unconditional right to receive consideration from its customers. Contract assets consist of the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditioned on something other than the passage of time. ASC 606 also requires an entity to present a revenue contract as a contract liability in instances when a customer pays consideration, or an entity has a right to an amount of consideration that is unconditional (e.g. receivable), before the entity transfers a good or service to the customer. The opening and closing contract asset and contract liability balances are not material.

There were no impairment losses recognized on the Company’s accounts receivable or contract assets during the three and six months ended July 29, 2018. There were no significant changes in the contract assets or the contract liabilities for the three and six months ended July 29, 2018.

Practical Expedients:

Unsatisfied Performance Obligations: Because all of the Company’s performance obligations relate to contracts with a duration of less than one year, the Company elected to apply the optional exemption provided in ASC 606 and, therefore, is not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.

Contract Costs: All incremental customer contract acquisition costs are expensed as they are incurred as the amortization period of the asset that the Company otherwise would have recognized is one year or less in duration.

Significant Financing Component: The Company does not adjust the promised amount of consideration for the effects of a significant financing component as the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

Sales Tax Exclusion from the Transaction Price: The Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from the customer.

Shipping and Handling Activities: The Company accounts for shipping and handling activities performed after a customer obtains control of the good as activities to fulfill the promise to transfer the good.

Note 3: Earnings per Share

The computation of basic and diluted earnings per common share was as follows:

	Three Months Ended				Six Months Ended
(in thousands, except per share amounts)	July 29, 2018		July 30, 2017		July 29, 2018		July 30, 2017
Net income	$	25,169	$	12,564	$	37,551	$	24,385
Weighted average common shares outstanding - basic	66,063		65,763		66,194		65,801
Dilutive effect of stock options and restricted stock units	2,817		1,707		2,234		1,620
Weighted average common shares outstanding - diluted	68,880		67,470		68,428		67,421
Basic earnings per common share	$	0.38	$	0.19	$	0.57	$	0.37
Diluted earnings per common share	$	0.37	$	0.19	$	0.55	$	0.36
Anti-dilutive shares not included in the above calculations	202		254		364		385

Basic earnings per common share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings per common share incorporates the incremental shares issuable, calculated using the treasury stock method, upon the assumed exercise of non-qualified stock options, the vesting of restricted stock units and performance unit awards if the conditions have been met.

Warrant. On October 5, 2016, the Company issued a warrant (the "Warrant") to Comcast Cable Communications Management LLC ("Comcast") to purchase up to 1,086,957 shares (the "Warrant Shares") of the common stock of Semtech Corporation. The Warrant was issued by the Company to Comcast in connection with an agreement between the parties regarding the intended trial deployment by Comcast of a low-power wide-area network ("LPWAN") in the United States, based on the Company’s LoRa® devices and wireless radio frequency technology. The Warrant was accounted for as equity and the cost was recognized as an offset to net sales over the respective performance period. The Warrant consisted of five performance tranches. The cost associated with each tranche had been recognized based on the fair value at each reporting date until vesting which was the measurement date. On April 27, 2018, the Company accelerated the vesting of the remaining 586,956 unvested shares from the Warrant, resulting in the full recognition of the remaining costs to be recognized for the Warrant. For the six month period ended July 29, 2018, the revenue offset reflects the cost associated with the Warrant of $21.5 million, including $15.9 million, related to the acceleration. The Warrant is now fully-vested and exercisable for a total of 869,565 shares, with no additional costs to be recognized in future periods.

Performance-Based Restricted Stock Units. The Company grants performance-based restricted stock units to select employees. The performance-based restricted stock units are valued as of the measurement date and expense is recognized on a straight line basis for the awards expected to vest based on the probability of attainment of the performance condition for each separately vesting portion of the award.

In the first quarter of fiscal year 2019, the Company granted 200,442 performance-based restricted stock units that have a pre-defined market condition and a service condition that are accounted for as equity awards. The market condition is determined based upon the Company’s total stockholder return ("TSR") benchmarked against the TSR of the S&P SPDR Semiconductor ETF (NYSE:XSD) over a one, two and three year period (one-third of the awards vesting each performance period). The fiscal year 2019 award recipients must be employed for the entire performance period and be an active employee at the time of vesting of the awards. The Company used a Monte Carlo simulation to determine the grant-date fair value for these awards, which takes into consideration the possible outcomes pertaining to the TSR market condition. The grant-date fair value per unit of the awards granted in the first quarter of fiscal year 2019 for each one, two and three year performance period is $33.02, $34.85 and $36.52, respectively.

Award Modifications. In the first quarter of fiscal year 2019, the Company modified the terms of 159,000 fully vested shares held by 8 employees. As a result of the modification, additional compensation cost of $2.8 million was recognized during the first quarter of fiscal year 2019.

The Company's available-for-sales securities consisted of investments in convertible debt instruments issued by privately-held companies and is included in "Other current assets" within the Balance Sheets.

The Company currently has a $30.0 million investment in a private entity that is accounted for at cost and included in "Other assets" within the Balance Sheets. As part of its investment, the Company received a call option that would have allowed the Company to purchase all of the outstanding equity of the entity. The Company did not exercise the call option, which expired on June 30, 2018.

Note 6: Fair Value Measurements

Instruments Measured at Fair Value on a Recurring Basis

Financial assets and liabilities measured and recorded at fair value on a recurring basis were presented within the Company's Balance Sheets as follows:

	Fair Value as of July 29, 2018								Fair Value as of January 28, 2018
(in thousands)	Total		(Level 1)		(Level 2)		(Level 3)		Total		(Level 1)		(Level 2)		(Level 3)
Financial assets:
Convertible debt	$	2,605	$	—	$	—	$	2,605	$	1,960	$	—	$	—	$	1,960
Total financial assets	$	2,605	$	—	$	—	$	2,605	$	1,960	$	—	$	—	$	1,960
Financial liabilities:
AptoVision Earn-out	$	20,100	$	—	$	—	$	20,100	$	21,000	$	—	$	—	$	21,000
Cycleo Earn-out	668		—		—		668		668		—		—		668
Derivative financial instruments	126		—		126		—		—		—		—		—
Total financial liabilities	$	20,894	$	—	$	126	$	20,768	$	21,668	$	—	$	—	$	21,668

During the six months ended July 29, 2018, the Company had no transfers of financial assets or liabilities between Level 1, Level 2 or Level 3. As of July 29, 2018 and January 28, 2018, the Company had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.

The fair values of the foreign exchange forward contracts are valued using Level 2 inputs. Foreign currency forward contracts are valued using readily available foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to the present value. Contracts in a gain position are recorded in the Balance Sheets within the caption "Other current assets" and the value of contracts in a loss position are recorded within the caption "Accrued liabilities" within the Balance Sheets. Please see Note 15 for further discussion of the Company’s derivative instruments.

The convertible debt is valued using probability weighted cash flows (Level 3 inputs).

The AptoVision Earn-out liability is valued utilizing estimates of annual revenue, adjusted earnings and product development targets (Level 3 inputs) through July 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Cycleo Earn-out liability (see Note 11) is valued utilizing estimates of annual revenue and operating income (Level 3 inputs) through April 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Company measures contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liabilities will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. For the Cycleo Earn-out and AptoVision Earn-out, these companies have business profiles comparable to a start-up company. Accordingly, their respective revenue projections are subject to significant revisions. This characteristic can result in volatile changes to the measurement of fair value for a given earn-out.

The Company reviews and re-assesses the estimated fair value of contingent consideration on a recurring basis, and the updated fair value could differ materially from the previous estimates. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

A reconciliation of the change in the earn-out liability during the six months ended July 29, 2018 is as follows:

(in thousands)	AptoVision			Cycleo		Total
Balance at January 28, 2018	$	21,000		$	668	$	21,668
Changes in the fair value of contingent earn-out obligations	(900		)	—		(900		)
Balance as of July 29, 2018	$	20,100		$	668	$	20,768

Instruments Not Recorded at Fair Value on a Recurring Basis

Some of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents including money market deposits, net receivables, certain other assets, accounts payable, accrued expenses, accrued personnel costs, and other current liabilities.

The Company’s long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes. The fair value of the Company’s Term Loans (as defined in Note 9) is $123.8 million and $131.3 million as of July 29, 2018 and January 28, 2018, respectively. The fair value of the Company's Revolving Commitments (as defined in Note 9) is$97.0 million as of both July 29, 2018 and January 28, 2018, respectively. These are based on Level 2 inputs which are derived from transactions with similar amounts, maturities, credit ratings and payment terms.

Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis

The Company reduces the carrying amounts of its goodwill, intangible assets, long-lived assets and non-marketable equity securities to fair value when held for sale or determined to be impaired.

For its investment in non-marketable equity interests, the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of its equity investments during the first six months of fiscal year 2019.

Note 7: Inventories

Inventories, consisting of material, material overhead, labor, and manufacturing overhead, are stated at the lower of cost (first-in, first-out) or market and consist of the following:

(in thousands)	July 29, 2018		January 28, 2018
Raw materials	$	2,376	$	1,651

Note 8: Goodwill and Intangible Assets

Goodwill – Changes in the carrying amount of goodwill by applicable reporting unit were as follows:

(in thousands)	Signal Integrity		Wireless and Sensing		Protection		Total
Balance at January 28, 2018	$	274,085	$	67,812	$	—	$	341,897
Additions	—		—		4,834		4,834
Balance at July 29, 2018	$	274,085	$	67,812	$	4,834	$	346,731

As a result of the realignment of its operating segments, during the first quarter of fiscal year 2019, the Company combined the Wireless and Sensing and the Power and High-Reliability reporting units (see Note 12). Goodwill of $49.4 million related to the Power and High-Reliability reporting unit which was previously a separate reporting unit is now included in the Wireless and Sensing reporting unit’s goodwill balance. The reporting units are the same as the operating segments which are part of a single reportable segment. The difference between the fair value and the carrying amount of these reporting units is one of several factors the Company will consider before reaching its conclusion about whether to perform the first step of the goodwill impairment test.

Purchased Intangibles – The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions, which continue to be amortized:

		July 29, 2018							January 28, 2018

On November 15, 2016, the Company, with certain of its domestic subsidiaries or guarantors, entered into an amended and restated credit facility with the lenders party thereto and HSBC Bank USA, National Association, as administrative agent, swing line lender and letter of credit issuer, consisting of a $150.0 million senior secured term loan (“Term Loan”) and a $250.0 million senior secured revolving credit facility (“Revolving Credit Facility”), collectively, the “credit facilities”. The Credit Facilities are scheduled to mature on November 12, 2021.

The outstanding principal balance of the Term Loans is subject to repayment in quarterly installments. No amortization is required with respect to the Revolving Credit Facility. As of July 29, 2018, we were in compliance with all financial covenants required under the credit facilities.

Scheduled maturities of current and long-term Term Loans are as follows:

(in thousands)
Fiscal Year Ending:
2019	$	8,438
2020	18,750
2021	19,687

Note 10: Income Taxes

The Company’s effective tax rate differs from the statutory federal income tax rate of 21% primarily due to regional mix of income and a partial release of the valuation allowance in the U.S. The valuation allowance was released in the first quarter of fiscal year 2019 as a result of the Company obtaining the information necessary to evaluate the impact of the Global Intangible Low-Taxed Income (“GILTI”) provisions, enacted as part of the Tax Cuts and Jobs Act (“Tax Act”) on December 22, 2017. This item was left open under Staff Accounting Bulletin 118 (“SAB 118”) in the financial statements for the year ended January 28, 2018 and the Company has now made a reasonable estimate based on the most current information available.

The Tax Act made significant changes to U.S. income tax laws, including transitioning from a worldwide tax system to a territorial tax system. This change in the U.S. international tax system included the introduction of several new tax regimes that are effective as of January 1, 2018, including the GILTI provisions. The GILTI provisions effectively tax the foreign earnings of U.S. multinational companies at 10.5%, half the current corporate tax rate. During the three months ended April 29, 2018, the Company finalized its analysis regarding the interplay of the foreign tax credits associated with this income, which are allowed against the U.S. tax liability generated as a result of the GILTI provision, and the potential impact on the related valuation allowance. As a result, the Company recorded a tax benefit of $15.8 million during the first quarter of fiscal year 2019 related to the reduction of the valuation allowance on certain U.S. deferred tax assets generated prior to fiscal year 2019.

While management believes the provisional amounts recorded during the six months ended July 29, 2018 and the year ended January 28, 2018 represent reasonable estimates of the ultimate impact U.S. tax reform will have on the Company's consolidated financial statements, it is possible the Company may continue to materially adjust these amounts for related administrative guidance, notices, implementation regulations, potential legislative amendments and interpretations as the Tax Act continues to evolve. These adjustments could have an impact on the Company's Balance Sheets and Statements of Income.

The Company uses a two-step approach to recognize and measure uncertain tax positions ("UTP"). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. 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.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (before the federal impact of state items) is as follows:

(in thousands)
Balance at January 28, 2018	$	16,059
Additions based on tax positions related to the current year	855
Balance as of July 29, 2018	$	16,914

Included in the balance of gross unrecognized tax benefits at July 29, 2018 and January 28, 2018, are $4.7 million and $3.9 million, respectively, of net tax benefits (after federal impact of state items), that, if recognized, would impact the effective tax rate, prior to consideration of any required valuation allowance.

The liability for UTP is reflected within the Balance Sheets as follows:        

(in thousands)	July 29, 2018		January 28, 2018
Deferred tax assets - non-current	$	12,236	$	12,135
Other long-term liabilities	4,678		3,924
Total accrued taxes	$	16,914	$	16,059

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits within the "Provision for taxes" in the Statements of Income.

Tax years prior to 2013 (the Company’s fiscal year 2014) are generally not subject to examination by the U.S. Internal Revenue Service ("IRS") except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. For state returns, the Company is generally not subject to income tax examinations for calendar years prior to 2012 (the Company’s fiscal year 2013). The Company has a significant tax presence in Switzerland for which Swiss tax filings have been examined through fiscal year 2017. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.

The Company’s regional income from continuing operations before taxes and equity in net losses of equity method investments is as follows:

	Three Months Ended						Six Months Ended
(in thousands)	July 29, 2018			July 30, 2017			July 29, 2018			July 30, 2017

Note 11: Commitments and Contingencies

In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. The Company also discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued, and makes adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount. The Company may be unable to estimate a possible loss or range of possible loss due to various reasons, including, among others: (i) if the damages sought are indeterminate; (ii) if the proceedings are in early stages, (iii) if there is uncertainty as to the outcome of pending appeals, motions or settlements, (iv) if there are significant factual issues to be determined or resolved, and (v) if there are novel or unsettled legal theories presented. In such instances, there is considerable uncertainty regarding the ultimate resolution of such matters, including a possible eventual loss, if any.

Because the outcomes of litigation and other legal matters are inherently unpredictable, the Company’s evaluation of legal matters or proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved matters and proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. However, legal matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond the Company’s control.

As such, even though the Company intends to vigorously defend itself with respect to its legal matters, there can be no assurance that the final outcome of these matters will not materially and adversely affect the Company’s business, financial condition, operating results, or cash flows.

From time to time, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to IP, contract, product liability, employment, and environmental matters. In the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole.

The Company’s currently pending legal matters of note are discussed below:

Environmental Matters

The Company vacated a former facility in Newbury Park, California in 2002, but continues to address groundwater and soil contamination at the site.

The Company’s efforts to address site conditions have been at the direction of the Los Angeles Regional Water Quality Control Board (“RWQCB”). In October 2013, an order was issued including a scope of proposed additional site work, monitoring, and proposed remediation activities. The Company filed appeals of the October 2013 order seeking reconsideration by the RWQCB and review by the State Water Resources Control Board ("SWRCB") of the removal of two other potentially responsible parties, and seeking clarification of certain other factual findings. In April 2015, the RWQCB denied the Company’s request to name the two other potentially responsible parties to the order, but did correct certain findings of fact identified by the Company in its petition for reconsideration. The SWRCB has not yet ruled on the Company’s petition for review of the RWQCB’s action as the petition was filed with a request it be held in abeyance.

The Company has been complying with RWQCB orders and direction, and is implementing an approved remedial action plan (prepared by an environmental firm retained by the Company) addressing the cleanup of soil, groundwater, and soil vapor at the site.

The Company has accrued liabilities where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. Based on the latest determinations by the RWQCB and the most recent actions taken pursuant to the remedial action plan, the Company continues to estimate the range of probable loss between $3.6 million and $7.2 million.Given the uncertainties associated with environmental assessment and the remediation activities, the Company is unable to determine a best estimate within the range of loss. Therefore, the Company has recorded the minimum amount of probable loss. These estimates could change as a result of changes in planned remedial actions, further actions from the regulatory agency, remediation technology, and other factors.

Indemnification

The Company has entered into agreements with its current and former executives and directors indemnifying them against certain liabilities incurred in connection with the performance of their duties. The Company’s Certificate of Incorporation and Bylaws contain comparable indemnification obligations with respect to the Company’s current directors and employees.

Product Warranties

The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances the Company has agreed to other or additional warranty terms, including indemnification provisions.

The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense has been immaterial to the Company’s consolidated financial statements.

Earn-out Liability

Pursuant to the terms of the amended earn-out arrangement ("Cycleo Earn-out") with the former shareholders of Cycleo SAS ("Cycleo Earn-out Beneficiaries"), which the Company acquired on March 7, 2012, the Company potentially may make payments totaling up to approximately $16.0 million based on the achievement of a combination of certain revenue and operating income milestones over a defined period ("Cycleo Defined Earn-out Period"). The Cycleo Defined Earn-out Period covers the period April 27, 2015 to April 26, 2020. For certain of the Cycleo Earn-out Beneficiaries, payment of the earn-out liability is contingent upon continued employment and is accounted for as post-acquisition compensation expense over the service period. The portion of the earn-out liability that is not dependent on continued employment is not considered as compensation expense. The Company has recorded a liability for the Cycleo Earn-out of $6.1 million and $5.5 million as of July 29, 2018 and January 28, 2018, respectively, of which $2.2 million is expected to be paid within twelve months.

Pursuant to the terms of the AptoVision Earn-out ("AptoVision Earn-out") with the former shareholders of AptoVision ("AptoVision Earn-out Beneficiaries"), which the Company acquired on July 1, 2017, the Company potentially may make payments totaling up to approximately $47.0 million based on the achievement of a combination of certain net revenue, adjusted earnings and product development targets measured from the acquisition date through July 26, 2020.

A summary of earn-out liabilities, included in "Accrued liabilities" and "Other long-term liabilities", by classification follows:

	Balance at July 29, 2018						Balance at January 28, 2018
(in thousands)	Cycleo		AptoVision		Total		Cycleo		AptoVision		Total

Note 12: Segment Information

Segment Information

The Company’s CEO functions as the CODM. The Company’s CODM makes operating decisions and assesses performance based on these operating segments. As part of a realignment strategy, during the first quarter of fiscal year 2019, the Company restructured and combined the Power and High Reliability operating segment with the Wireless and Sensing operating segment to better align resources with our LoRa® initiatives. This resulted in the Company having three operating segments compared to previously having four operating segments. The three operating segments: Protection, Signal Integrity, and Wireless and Sensing, all have similar economic characteristics and have been aggregated into one reportable segment identified in the table below as the "Semiconductor Products Group".

The Company’s assets are commingled among the various operating segments and the CODM does not use that information in making operating decisions or assessing performance. Therefore, the Company has not included asset information by segment below.

Note 15: Derivatives and Hedging Activities

The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company uses derivative financial instruments in the form of forward contracts to mitigate risk associated with adverse movements in these foreign currency exchange rates on a portion of foreign denominated expenses expected to be realized during the current and following fiscal year. Currency forward contracts involve fixing the exchange rate for delivery of a specified amount of foreign currency on a specified date.

The Company’s accounting treatment for these instruments is based on whether or not the instruments are designated as a hedging instrument. The Company is currently applying hedge accounting to all foreign currency derivatives and has designated these hedges as cash flow hedges.

At July 29, 2018, the Company had the following outstanding foreign exchange contracts:

(in thousands)
Foreign Exchange Contracts	Number of Instruments	Sell Notional Value		Buy Notional Value
Sell USD/Buy CAD Forward Contract	6	$	8,560	C$	11,000
Total	6

These contracts met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of "Accumulated other comprehensive loss" within the Balance Sheet. The effective portions of cash flow hedges are recorded in accumulated other comprehensive income or loss ("AOCI") until the hedged item is recognized in SG&A expense within the Statements of Income when the underlying hedged expense is recognized. Any ineffective portions of cash flow hedges are recorded in "Non-operating expense, net" within the Company’s Statements of Income. The Company presents its derivative assets and liabilities at their gross fair values on the Balance Sheets.

The Company had no outstanding foreign exchange contracts at January 28, 2018. The table below summarizes the carrying values of derivative instruments as of July 29, 2018:

	Carrying Values of Derivative Instruments as of July 29, 2018

⁽¹⁾ On October 5, 2016, we issued a warrant (the "Warrant") to Comcast Cable Communications Management LLC ("Comcast") to purchase up to 1,086,957 shares (the "Warrant Shares") of our common stock. The Warrant was issued by us to Comcast in connection with an agreement between the parties regarding the intended trial deployment by Comcast of a low-power wide-area Network ("LPWAN") in the United States, based on our LoRa® devices and wireless radio frequency technology. The Warrant is accounted for as equity and the cost is

recognized as an offset to net sales. The Warrant is now fully-vested and exercisable for a total of 869,565 shares, with no additional costs to be recognized in future periods.

The following significant customers accounted for at least 10% of net sales in one or more of the periods indicated:

	Three Months Ended				Six Months Ended
(percentage of net sales)	July 29, 2018		July 30, 2017		July 29, 2018		July 30, 2017

Samsung Electronics (and affiliates)	7	%	7	%	7	%	7	%
Premier Technical Sales Korea, Inc. (and affiliates) (1)	4	%	6	%	5	%	6	%

⁽¹⁾ Premier is a distributor with a concentration of sales to Samsung. The above percentages represent the Company's estimate of the sales activity related to Samsung that is passing through this distributor.

The following table shows the customers that have an outstanding receivable balance that represents at least 10% of total net receivables as of the dates indicated:

	Balance as of
(percentage of net sales)	July 29, 2018		January 28, 2018
Frontek Technology Corporation	12	%	9	%
Huawei Tech. Investment Co. Ltd.	10	%	8	%

Most of our sales to customers are made on the basis of individual customer purchase orders. Many customers include cancellation provisions in their purchase orders. Trends within the industry toward shorter lead-times and "just-in-time" deliveries have resulted in our reduced ability to predict future shipments. As a result, we rely on orders received and shipped within the same quarter for a significant portion of our sales. Orders received and shipped in the second quarter of fiscal years 2019 and 2018 represented 39% and 37% of net sales, respectively. Sales made directly to customers during the second quarter of fiscal years 2019 and 2018 were 33% and 36% of net sales, respectively. The remaining sales were made through independent distributors.Our business relies on foreign-based entities. Most of our outside subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in foreign countries, including China, Taiwan and Israel. For the second quarter of fiscal years 2019 and 2018, approximately 15% and 21%, respectively, of the Company’s silicon in terms of cost of wafers was supplied by a third-party foundry in China, and these percentages could be higher in future periods. Foreign sales during the second quarter of fiscal years 2019 and 2018 constituted approximately 90% and 91%, respectively, of our net sales. Approximately 75% and 81% of foreign sales during the second quarters of fiscal years 2019 and 2018, respectively, were to customers located in the Asia-Pacific region. The remaining foreign sales were primarily to customers in Europe, Canada, and Mexico.

We use several metrics as indicators of future potential growth. The indicators that we believe best correlate to potential future revenue growth are design wins and new product releases. There are many factors that may cause a design win or new product release not to result in sales, including a customer decision not to go to system production, a change in a customer’s perspective regarding a product’s value or a customer’s product failing in the end-market. As a result, although a design win or new product introduction is an important step towards generating future revenue, it does not inevitably result in us being awarded business or receiving a purchase commitment.

Historically, our results have reflected some seasonality, with demand levels generally lower in the enterprise computing and high-end consumer end-markets during the first and fourth quarters of our fiscal year in comparison to the second and third quarters.

Critical Accounting Policies and Estimates

In addition to the discussion below, please refer to the disclosures regarding our critical accounting policies in "Management’s Discussion and Analysis of Financial Condition and Results of Operations" included in Item 7 of our Annual Report on Form 10-K for the fiscal year ended January 28, 2018 filed with the Securities and Exchange Commission ("SEC") on March 22, 2018.

Fiscal Periods

We report results on the basis of 52 and 53 week periods and end our fiscal year on the last Sunday in January. The other quarters generally end on the last Sunday of April, July and October. All quarters consist of 13 weeks except for one 14-week period in the fourth quarter of 53-week years. The second quarter of fiscal years 2019 and 2018 each consisted of 13 weeks.

Revenue and Cost of Sales

We derive our revenue primarily from the sale of semiconductor products into various end markets. Revenue is recognized when control of these products is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for these products. Control is generally transferred when products are shipped and, to a lesser extent, when the products are delivered. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed and are reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts. We include revenue related to granted technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of our recurring ordinary business.

We determine revenue recognition through the following five steps:

• Identification of the contract, or contracts, with a customer

• Identification of the performance obligations in the contract

• Determination of the transaction price

• Allocation of the transaction price to the performance obligations in the contract

• Recognition of revenue when, or as, performance obligations are satisfied

We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Our revenue contracts generally represent a single performance obligation to sell our products to trade customers. Net sales reflect the transaction prices for contracts, which include units shipped at selling prices reduced by variable consideration. Determination of variable consideration requires judgment by us. Variable consideration includes expected sales returns and other price adjustments. Variable consideration is estimated using the expected value method considering all reasonably available information, including our historical experience and our current expectations, and is reflected in the transaction price when sales are recorded. Sales returns are generally accepted at our discretion or from distributors with such rights. Our contracts with trade customers do not have significant financing components or non-cash consideration. We record net sales excluding taxes collected on our sales to our trade customers.

We provide an assurance type warranty which is typically not sold separately and does not represent a separate performance obligation. Our payment terms are generally aligned with shipping terms (See Note 2).

On October 5, 2016, we issued a Warrant to Comcast to purchase up to 1,086,957 Warrant Shares of our common stock. The cost of the Warrant is recognized as an offset to net sales. On April 27, 2018, we accelerated the vesting of the remaining 586,956 unvested shares from the Warrant ("Acceleration Event"), resulting in the full recognition of the previously unrecognized costs. For the first quarter of fiscal year 2019, the revenue offset reflects the cost associated with the Warrant of $21.5 million, including $15.9 million related to the Acceleration Event. The Warrant is now fully-vested and exercisable for a total of 869,565 shares. No additional Warrant related costs will be recognized in future periods following the first quarter of fiscal year 2019.

Gross Profit

Gross profit is equal to our net sales less our cost of sales. Our cost of sales includes materials, depreciation on fixed assets used in the manufacturing process, shipping costs, direct labor and overhead. We determine the cost of inventory by the first-in, first-out method.

Operating Costs

Our operating costs and expenses generally consist of selling, general and administrative, product development and engineering costs, costs associated with acquisitions, restructuring charges, and other operating related charges.

NetSales

Net sales for the second quarter of fiscal year 2019 were $163.2 million, an increase of 7% compared to $153.1 million for the second quarter of fiscal year 2018. During the second quarter of fiscal year 2019, China based demand continued to grow driven by strength in our LoRa® products, which drove overall growth in the industrial end-market. The Warrant Shares fully vested in the first quarter of fiscal year 2019, and therefore, did not impact net sales in the second quarter of fiscal year 2019.

Based on recent bookings trends and our backlog entering the quarter, we estimate net sales for the third quarter of fiscal year 2019 to be between $168.0 million and $178.0 million.

Gross Profit

In the second quarter of fiscal year 2019, gross profit increased to $100.1 million from $92.2 million in the second quarter of fiscal year 2018. Gross margins were 61.3% in the second quarter of fiscal year 2019 compared to 60.2% in the second quarter of fiscal year 2018. In the second quarter of fiscal year 2019, gross margin was favorably impacted by the Acceleration Event, which eliminated the offset to net sales due to the Warrant.

In the third quarter of fiscal year 2019, we expect our gross margins to be in the range of 61.0% to 62.0%.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses decreased in the second quarter of fiscal year 2019 compared to the same quarter of fiscal year 2018 as a result of a $6.6 million offset to expense from proceeds related to the settlement of a lawsuit against HiLight Semiconductor Limited ("HiLight") and related defendants. This was partially offset by higher share-based compensation costs. The higher levels of share-based compensation expense resulted primarily from the impact of a higher stock price on the related fair value re-measurement of awards accounted for as liabilities.

Product Development and Engineering Expenses

Product development and engineering expenses increased slightly in the second quarter of fiscal year 2019 compared to the second quarter of fiscal year 2018 as a result of marginally lower recoveries from third parties for non-recurring engineering services.

The levels of product development and engineering expenses reported in a fiscal period can be significantly impacted, and therefore experience period over period volatility, by the number of new product tape-outs and by the timing of recoveries from non-recurring engineering services which are typically recorded as a reduction to product development and engineering expense.

33

Intangible Amortization

Intangible amortization was $6.5 million and $6.7 million in the second quarter of fiscal years 2019 and 2018, respectively.

Interest Expense

Interest expense and amortization of debt discounts was $2.2 million and $2.0 million in the second quarter of fiscal years 2019 and 2018, respectively. The impact of higher interest rates was partially offset by lower overall debt levels.

We expect the interest rates on our credit facilities to be relatively stable in the third quarter of fiscal year 2019. See "Liquidity and Capital Resources" for a description of our credit facilities.

Income Taxes

The effective tax rates for the second quarter of fiscal years 2019 and 2018 were 19.5% and 24.6%, respectively. In the second quarter of fiscal year 2019, we recorded an income tax provision of $6.1 million, compared to $4.1 million in the second quarter of fiscal year 2018. The effective tax rate in the second quarter of fiscal year 2019 was lower than the effective tax rate in the second quarter of fiscal year 2018 primarily due to higher pre-tax book income and timing of regional earnings in fiscal year 2019. Our effective tax rate in the second quarter of fiscal year 2019 differs from the statutory federal income tax rate of 21% primarily due to regional mix of income.

As a global organization, we are subject to audit by taxing authorities in various jurisdictions. To the extent that an audit, or the closure of a statute of limitations, results in adjusting our reserves for uncertain tax positions, our effective tax rate could experience extreme volatility since any adjustment would be recorded as a discrete item in the period of adjustment.

NetSales

Net sales for the first six months of fiscal year 2019 were $293.6 million, a decrease of 1.1% compared to $296.9 million for the first six months of fiscal year 2018. During the first six months of fiscal year 2019, mobile sales in China were lower and the Acceleration Event reduced net sales by an incremental $15.9 million. This was partially offset by growing demand for our LoRa® products.

Gross Profit

In the first six months of fiscal year 2019, gross profit decreased to $171.6 million from $177.2 million in the first six months of fiscal year 2018. Gross margins were 58.4% in the first six months of fiscal year 2019 compared to 59.7% in the first six months of fiscal year 2018. In the first six months of fiscal year 2019, gross margin was adversely impacted by the Acceleration Event which reduced our gross profit by $15.9 million.

Selling, General and Administrative Expenses

SG&A expenses increased in the first six months of fiscal year 2019 compared to the first six months of fiscal year 2018 as a result of higher share-based compensation costs and an increase in our supplemental compensation costs resulting from our improved financial performance. The higher levels of share-based compensation reflect the impact of an award modification and the related fair value re-measurement of awards accounted for as liabilities rather than equity due to an increase in our stock price. This was partially offset by a $6.6 million reduction to expense from proceeds related to the settlement of a lawsuit against HiLight and related defendants.

Product Development and Engineering Expenses

Product development and engineering expenses increased slightly in the first six months of fiscal year 2019 compared to the first six months of fiscal year 2018. The levels of product development and engineering expenses reported in a fiscal period can be significantly impacted, and therefore experience period over period volatility, by the number of new product tape-outs and by the timing of recoveries from non-recurring engineering services which are typically recorded as a reduction to product development and engineering expense.

Intangible Amortization

Intangible amortization was $13.4 million and $13.0 million in the first six months of fiscal years 2019 and 2018, respectively.

Interest Expense

Interest expense and amortization of debt discounts was $4.4 million and $4.1 million in the first six months of fiscal years 2019 and 2018, respectively. The impact of higher interest rates was partially offset by lower overall debt levels.

Income Taxes

The effective tax rates for the first six months of fiscal years 2019 and 2018 were a provision benefit of 43.7% and provision of 24.4%, respectively. In the first six months of fiscal year 2019, we recorded an income tax benefit of $11.4 million, compared to a tax provision of $7.9 million in the first six months of fiscal year 2018. The effective tax rate in the first six months of fiscal year 2019 was lower than the effective tax rate in the first six months of fiscal year 2018 primarily due to a partial release of the valuation reserve against our U.S. deferred tax assets. Our effective tax rate in the first six months of fiscal year 2019 differs from the statutory federal income tax rate of 21% primarily due to regional mix of income and a partial release of the valuation reserve against our U.S. deferred tax assets.

In connection with the enactment of the Tax Cuts and Jobs Act ("Tax Act"), we have determined that we will remit approximately $240.0 million of foreign earnings in the foreseeable future, and as a result, have established a deferred income tax liability for the withholding tax that will be due upon distribution of these earnings. We intend to indefinitely reinvest all other unremitted foreign earnings and, as a result, have not provided U.S. taxes on these earnings. We currently do not need these earnings to support our U.S. operations. If these unremitted foreign earnings are needed for our U.S. operations or can no longer be permanently reinvested outside the U.S., we would be required to accrue and pay foreign withholding taxes of approximately 5% on these earnings.

As a global organization, we are subject to audit by taxing authorities in various jurisdictions. To the extent that an audit, or the closure of a statute of limitations, results in our adjusting our reserves for uncertain tax positions, our effective tax rate could experience extreme volatility since any adjustment would be recorded as a discrete item in the period of adjustment.

Liquidity and Capital Resources

Our capital requirements depend on a variety of factors, including but not limited to, the rate of increase or decrease in our existing business base; the success, timing and amount of investment required to bring new products to market; revenue growth or decline; and potential acquisitions. We believe that we have the financial resources necessary to meet business requirements for the next 12 months, including funds needed for working capital requirements.

35

As of July 29, 2018, our total stockholders’ equity was $703.3 million. At that date, we also had approximately $311.3 million in cash and cash equivalents and $219.3 million of borrowings, net of debt discount.

We incur significant expenditures in order to fund the development, design, and manufacture of new products. We intend to continue to focus on those areas that have shown potential for viable and profitable market opportunities, which may require additional investment in equipment and the hiring of additional design and application engineers aimed at developing new products. Certain of these expenditures, particularly the addition of design engineers, do not generate significant payback in the short-term. We plan to finance these expenditures with cash generated by our operations and our existing cash balances.

A meaningful portion of our capital resources, and the liquidity they represent, are held by our foreign subsidiaries. As of July 29, 2018, our foreign subsidiaries held approximately $268.8 million of cash and cash equivalents compared to $215.1 million at January 28, 2018. Additionally, in connection with the enactment of the Tax Act, we determined that we will remit approximately $240.0 million of foreign earnings in the foreseeable future, and as a result, we have updated our assertion to reflect this change. As of July 29, 2018, our foreign subsidiaries had $439.3 million of unremitted earnings for which no taxes have been provided. These historical earnings have been and are expected to continue to be permanently reinvested.

One of our primary goals is to improve the cash flows from our existing business activities. Additionally, we will continue to seek to maintain and improve our existing business performance with capital expenditures and, potentially, acquisitions and other investments that support achievement of our business strategies. Acquisitions may be made for either cash or stock consideration, or a combination of both.

Operating Activities

Net cash provided by operating activities is primarily due to net income adjusted for non-cash items plus fluctuations in operating assets and liabilities.

Operating cash flow for the first six months of fiscal year 2019 was favorably impacted by higher net income, lower inventory spend to align with the Company's strategic objectives and proceeds from the HiLight settlement. This was partially offset by the disbursement of $17.9 million of supplemental compensation, which is aligned with our financial performance and is normally settled in the first quarter of each fiscal year.

Investing Activities

Cash flows from investing activities is primarily attributable to capital expenditures, net of proceeds from sales of property, plant and equipment and proceeds from sales of investments. Investing activities are also impacted by acquisitions, net of any cash received.

Capital expenditures were $9.8 million for the first six months of fiscal year 2019 compared to $19.0 million for the first six months of fiscal year 2018.

On May 2, 2018, we acquired IC Interconnect, Inc., a privately-held, U.S.-based company for approximately $7.3 million. We funded the purchase price using our existing cash balances.

Financing Activities

Cash provided by financing activities is primarily attributable to borrowings under our revolving commitments offset by principal and interest payments related to our long-term debt and repurchase of outstanding common stock.

In the first six months of fiscal year 2019, we received $8.0 million in proceeds from the exercise of stock options compared to $2.3 million in the first six months of fiscal year 2018.

We do not directly control the timing of the exercise of stock options. Such exercises are independent decisions made by grantees and are influenced most directly by the stock price and the expiration dates of stock option awards. Such proceeds are difficult to forecast, resulting from several factors which are outside our control. We believe that such proceeds will remain a nominal source of cash in the future.

Stock Repurchase Program

We currently have in effect a stock repurchase program that was initially approved by our Board of Directors in March 2008. On May 24, 2018, our Board of Directors increased the authorization by $250.0 million.

This program represents one of our principal efforts to return value to our stockholders. We repurchased 1,140,753 shares under this program in the first six months of fiscal year 2019 for $49.7 million. In the first six months of fiscal year 2018, we repurchased 312,304 shares under this program for $10.4 million. As of July 29, 2018, remaining authorization under this program was $247.3 million.

Credit Facilities

On November 15, 2016 (the "Closing Date"), we entered into an amended and restated credit agreement (the "Credit Agreement") to refinance our prior credit agreement. We accounted for the Credit Agreement as a debt modification. Pursuant

36

to the Credit Agreement, the Lenders provided us with senior secured first lien credit facilities in an aggregate principal amount of $400.0 million, consisting of term loans in an aggregate principal amount of $150.0 million (the "Term Loans") and revolving commitments in an aggregate principal amount of $250.0 million (the "Revolving Credit Facility"). Up to $40.0 million of the Revolving Credit Facility may be used to obtain letters of credit, up to $25.0 million of the Revolving Credit Facility may be used to obtain swing line loans, and up to $40.0 million of the Revolving Credit Facility may be used to obtain revolving loans and letters of credit in certain currencies other than U.S. Dollars ("Alternative Currencies"). Each of the credit facilities is scheduled to mature on November 12, 2021.

As of July 29, 2018 we have $123.8 million outstanding under our Term Loans and $97.0 million outstanding under our Revolving Credit Facility.

As of July 29, 2018, $153.0 million of the Revolving Credit Facility were undrawn. The proceeds of the revolving credit facilities may be used by us for capital expenditures, permitted acquisitions, permitted dividends, working capital and general corporate purposes.

The Credit Agreement provides that, subject to certain conditions, we may request, at any time and from time to time, the establishment of one or more additional term loan facilities and/or increases to the Revolving Credit Facility in an aggregate principal amount not to exceed the sum of (a) $150.0 million and (b) the aggregate principal amount of all voluntary prepayments of Term Loans made prior to the date of incurrence of such additional term loan facilities and/or increases to the Revolving Credit Facility; however, the Lenders are not required to provide such increase upon our request.

Interest on loans made under the Credit Agreement in U.S. Dollars accrues, at our option, at a rate per annum equal to (1) the Base Rate (as defined below) plus a margin ranging from 0.25% to 1.25% depending upon our consolidated leverage ratio or (2) LIBOR (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by us plus a margin ranging from 1.25% to 2.25% depending upon our consolidated leverage ratio (such margin, the "Applicable Margin"). The "Base Rate" is equal to a fluctuating rate equal to the highest of (a) the prime rate of the Administrative Agent, (b) ½ of 1% above the federal funds effective rate published by the Federal Reserve Bank of New York and (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars) plus 1.00%.

Interest on loans made under the Credit Agreement in Alternative Currencies accrues at a rate per annum equal to LIBOR (determined with respect to deposits in the applicable Alternative Currency) (other than loans made in Canadian Dollars, for which a special reference rate for Canadian Dollars applies) for an interest period to be selected by us plus the Applicable Margin.

The outstanding principal balance of the Term Loans was subject to repayment in equal quarterly installments beginning on the last day of our fiscal quarter ending closest to January 31, 2017 in an amount equal to 10.0% per annum of the original principal amount of the Term Loans on the Closing Date in the first two years after such date, is now subject to repayment in equal quarterly installments at 12.5% per annum in years three and four after the Closing Date, and 15.0% per annum in year five after such date, with the balance being due at maturity on November 12, 2021. No amortization is required with respect to the revolving credit facility. We may voluntarily prepay borrowings under the new credit facilities at any time and from time to time, without premium or penalty, other than customary "breakage costs" and fees for LIBOR-based loans.

The Term Loans must be mandatorily prepaid using the proceeds of certain dispositions of assets and receipt of insurance proceeds, subject to agreed upon thresholds and exceptions and customary reinvestment rights.

Off-Balance Sheet Arrangements     

We do not have any off-balance sheet arrangements, as those arrangements are defined by the SEC, that are reasonably likely to have a material effect on our financial condition, revenues or expenses, operating results, liquidity, capital expenditures or capital resources.

We do not have any unconsolidated subsidiaries or affiliated entities. We have no special purpose or limited purpose entities that provide off-balance sheet financing, liquidity or market or credit risk support. We do not engage in leasing, hedging, research and development services, or other relationships that expose us to liability that is not reflected on the face of the consolidated financial statements.

Contractual Obligations

There were no material changes in our contractual obligations during the first six months of fiscal year 2019 from those disclosed in "Management’s Discussion and Analysis of Financial Condition and Results of Operations" included in Item 7 of our Annual Report on Form 10-K for the fiscal year ended January 28, 2018 filed with the SEC on March 22, 2018.

Inflation

Inflationary factors have not had a significant effect on our performance over the past several years. A significant increase in inflation would affect our future performance if we were unable to pass these higher costs on to our customers.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

We are subject to a variety of market risks, including commodity risk and the risks related to foreign currency, interest rates and market performance that are discussed in Item 7A of our Annual Report on Form 10-K for fiscal year ended January 28, 2018 filed with the SEC on March 22, 2018. Many of the factors that can have an impact on our market risk are external to us, and so we are unable to fully predict them.

We do not engage in the trading of derivative financial instruments in the normal course of business to mitigate our risk related to interest rates. In the event interest rates were to increase 100 basis points and holding all other variables constant, annual net income and cash flows for the following year would decrease by approximately $1.7 million as a result of our variable-rate debt. The effect of the 100 basis points increase would not be expected to significantly impact the fair value of our variable-rate debt.

Our investments are primarily subject to credit risk. Our investments are managed by a limited number of outside professional managers following investment guidelines set by us. Such guidelines prescribe credit quality, permissible investments, diversification, and duration restrictions. These restrictions are intended to limit risk by restricting our investments to high quality debt instruments with relatively short-term durations. Our investment strategy limits investment of new funds and maturing securities to U.S. Treasury, Federal agency securities, high quality money market funds and time deposits with our principal commercial banks.

We considered the historical trends in foreign currency exchange rates and determined that it is reasonably possible that adverse changes in foreign exchange rates of 10% for all currencies could be experienced in the near-term. These reasonably possible adverse changes were applied to our total monetary assets and liabilities denominated in currencies other than our functional currency as of the second quarter of fiscal year 2019. The adverse impact these changes would have had (after taking into account balance sheet hedges only) on our income before taxes is $6.7 million.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, which are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our CEO and CFO, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on that evaluation, our CEO and CFO concluded that, our disclosure controls and procedures were effective as of July 29, 2018.

Changes in Internal Controls

As of July 29, 2018, there were no changes to our internal control over financial reporting that occurred during the fiscal quarter then ended that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. Legal Proceedings

Information about legal proceedings is set forth in Note 11 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report.

ITEM 1A. Risk Factors

Please carefully consider and evaluate all of the information in this Quarterly Report and the risk factors set forth in our Annual Report on Form 10-K for the fiscal year ended January 28, 2018 filed with the SEC on March 22, 2018. The risks set forth in our Annual Report on Form 10-K are not the only ones we face. Additional risks not now known to us or that we currently deem immaterial may also impair our business operations. If any of these risks actually occur, our business could be materially harmed. If our business is harmed, the trading price of our common stock could decline.

The risk factors associated with our business have not materially changed, as compared to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended January 28, 2018 filed with the SEC on March 22, 2018.

Exhibit 10.1

POLICY REGARDING DIRECTOR COMPENSATION

Effective June 14, 2018

Each director of Semtech Corporation (the “Company”) who is not employed by the Company or one of its subsidiaries (a “non-employee director”) is entitled to compensation for his or her service as a member of the Board of Directors of the Company (the “Board”) and related committees as set forth below. This policy is effective as of June 14, 2018 (the “Effective Date”) and supersedes all prior policies concerning compensation of the Company’s non-employee directors as to their service from and after that time. Nothing herein, however, modifies the terms and conditions of any stock option or stock unit award granted by the Company prior to the Effective Date.

Cash Compensation

Each non-employee director will be entitled to cash retainers while serving on the Board in the amounts set forth below:

Description	Annual Amount
Annual Retainer	$45,000
Additional Retainer for Chairman of the Board	$50,000
Committee Chair Retainer (Standing Committees)	Audit Committee: $20,000
	Compensation Committee: $20,000
	Nominating and Governance Committee: $10,000
Committee Retainers (Standing Committees)	Audit Committee: $10,000
	Compensation Committee: $10,000
	Nominating and Governance Committee: $5,000

The amounts of the Annual Retainer, the Annual Retainer for Chairman of the Board, the Committee Chair Retainers and the Committee Retainers are expressed as annualized amounts. These retainers will be paid on a quarterly basis in advance, with the amount for a particular quarter paid promptly after the beginning of the quarter. In the case of a non-employee director who commences such a position mid-quarter, the corresponding amount will be pro-rated for the portion of the quarter that the director is to serve in the particular position and paid as soon as practicable after the director commences such position.

For purposes of clarity, a non-employee director who serves as the Chair of a committee will be entitled to the Committee Chair Retainer for that particular committee but will not be entitled to the Committee Retainer for serving as a member of that particular committee. Also for purposes of clarity, a non-employee director who serves as a member of a committee and commences serving as Chair of that committee mid-quarter will be entitled to a pro-rated portion of the applicable Committee Chair Retainer for the portion of the quarter that the director is to serve in the particular position, less a pro-rated portion of the Committee Retainer for serving as a member of that particular committee for the portion of the quarter that the director serves as Chair of that committee.

Equity Awards

Effective as of June 14, 2018, each non-employee director will be eligible to receive the equity awards discussed below. Such equity awards will be made under and subject to the terms and conditions of the Company’s 2017 Long-Term Equity Incentive Plan or any successor equity compensation plan approved by the Company’s stockholders and in effect at the time of grant of the particular award (the “Plan”), and will be evidenced by, and subject to the terms and conditions of, an award agreement in the form approved by the Board to evidence such type of grant pursuant to this policy (the “Award Agreement”).

1

Annual Stock Unit Awards. On each July 1, each non-employee director then in office will automatically be granted two awards of restricted stock units. The first award (the “Annual Non-Deferred RSU Award”) will be for a number of restricted stock units determined by dividing $70,000 by the per-share closing price (in regular trading) of the Company’s common stock on the Nasdaq Stock Market on the grant date (or as of the last trading day preceding such date if the date of grant is not a trading day), rounded down to the nearest whole unit. Each Annual Non-Deferred RSU Award will vest in full on the earlier of (1) the one-year anniversary of the date of grant and (2) the date immediately preceding the date of the annual meeting of the Company’s stockholders for the year following the year of grant of the award, subject to the non-employee director’s continued service to the Company through such vesting date. To the extent then vested, restricted stock units subject to an Annual Non-Deferred RSU Award will be paid in an equal number of shares of the Company’s common stock as soon as practicable following (and in all events within two and one-half months after) the earlier to occur of (1) the one-year anniversary of the date of grant, or (2) the non-employee director’s separation from service on the Board.

The second award of restricted stock units (the “Annual Deferred RSU Award”) will be for a number of restricted stock units determined by dividing $80,000 by the per-share closing price (in regular trading) of the Company’s common stock on the Nasdaq Stock Market on the grant date (or as of the last trading day preceding such date if the date of grant is not a trading day), rounded down to the nearest whole unit. Each Annual Deferred RSU Award will vest in full on the earlier of (1) the one-year anniversary of the date of grant and (2) the date immediately preceding the date of the annual meeting of the Company’s stockholders for the year following the year of grant of the award, subject to the non-employee director’s continued service to the Company through such vesting date. To the extent then vested, restricted stock units subject to an Annual Deferred RSU Award will be paid in cash as soon as practicable following (and in all events within two and one-half months after) the non-employee director’s separation from service on the Board.

Outstanding and unvested Annual Non-Deferred RSU Awards and Annual Deferred RSU Awards will accelerate and vest (1) in full upon a change in control of the Company or should the non-employee director’s service with the Company terminate due to the director’s death or disability, or (2) as to a pro-rata portion of the Annual Non-Deferred RSU Award or the Annual Deferred RSU Award, as applicable, should the non-employee director’s service with the Company terminate due to any reason other than the director’s death or disability, with such pro-rata portion determined by multiplying (a) the total number of restricted stock units subject to the Annual Non-Deferred RSU Award or the Annual Deferred RSU Award, as applicable, by (b) a fraction (not greater than one), the numerator of which is the number of calendar days in the period beginning with the applicable grant date of the award through and including the date of the director’s termination of services, and the denominator of which is the number of calendar days in the period beginning with the applicable grant date of the award through and including the first July 1 that occurs after the applicable grant date of the award. Any restricted stock units subject to the Annual Non-Deferred RSU Award or the Annual Deferred RSU Award, as applicable, that are not vested on the date of the non-employee director’s termination of service with the Company (after giving effect to any accelerated vesting as described above) will be forfeited upon the non-employee director’s termination of service as a director for any reason.

Non-employee directors are entitled to receive dividend equivalents with respect to outstanding and unpaid restricted stock units subject to Annual Non-Deferred RSU Awards and Annual Deferred RSU Awards. Dividend equivalents, if any, are paid in the form of a credit of additional restricted stock units that are subject to the same vesting, payment and other provisions as the underlying restricted stock units.

The foregoing general provisions are, in the case of a particular Annual Non-Deferred RSU Award or Annual Deferred RSU Award, subject to the terms and conditions of the applicable Award Agreement.

Initial Equity Awards. Each non-employee director who is initially elected or appointed to the Board on or after June 14, 2018 (and who was not an employee of the Company or one of its subsidiaries immediately prior to joining the Board) will automatically (unless otherwise provided by the Board prior to or in connection with such election or appointment) be granted an initial non-deferred restricted stock unit award (“Initial Non-Deferred RSU Award”) and an initial deferred restricted stock unit award (“Initial Deferred RSU Award”). However, if such a non-employee director is initially elected or appointed to the Board on a July 1, the non-employee director will not receive an Initial Non-Deferred RSU Award or an Initial Deferred RSU Award as the non-employee director would be entitled to an Annual Non-Deferred RSU Award and an Annual Deferred RSU Award by virtue of being in office on such July 1.

Initial Non-Deferred RSU Awards and Initial Deferred RSU Awards will have the same terms and conditions as the Annual Non-Deferred RSU Awards and Annual Deferred RSU Awards, respectively, last granted by the Company prior to the date that the new non-employee director is elected or appointed to the Board, except that the number of restricted stock units subject to each such initial award will be determined by dividing the applicable dollar amount set forth above for the applicable annual award by the per-share closing price (in regular trading) of the Company’s common stock on the Nasdaq Stock Market on the grant date (or as of the last trading day preceding such date if the date of grant is not a trading day) of such initial award,

2

multiplying that number of units by the Initial Fraction (as defined below), and rounding the number of units so produced down to the nearest whole unit. For clarity, the vesting dates of each such Initial Non-Deferred RSU Award and Initial Deferred RSU Award will also correspond with the vesting dates applicable to the Annual Non-Deferred RSU Awards and Annual Deferred RSU Awards last granted by the Company prior to the date that the new non-employee director is elected or appointed to the Board. The “Initial Fraction” is the fraction (not greater than one) determined by dividing (1) the number of days in the period beginning with the date that the non-employee director is elected or appointed to the Board through and including the June 30 that coincides with or next follows that date, by (2) the number of calendar days in the calendar year that includes such June 30 (either 365 or 366).

The foregoing general provisions are, in the case of a particular Initial Non-Deferred RSU Award or Initial Deferred RSU Award, subject to the terms and conditions of the applicable Award Agreement.

Expense Reimbursement

All non-employee directors will be entitled to reimbursement from the Company for their reasonable travel expenses (including airfare and ground transportation) to attend meetings of the Board or committees thereof or in connection with other Board related business. The Company will make reimbursement to a non-employee director within a reasonable amount of time following submission by the non-employee director of reasonable written substantiation for the expenses, and in all cases not later than the end of the calendar year following the calendar year in which the related expense was incurred.

Amendment and Termination

The Board has the right to amend or terminate this policy at any time and from time to time.

Approved and Adopted June 14, 2018

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

Organization and Basis of Presentation

Nature of Business

Semtech Corporation (together with its consolidated subsidiaries, the "Company" or "Semtech") is a global supplier of analog and mixed-signal semiconductors and advanced algorithms. The end customers for the Company’s products are primarily original equipment manufacturers ("OEMs") that produce and sell electronics.

The Company designs, develops and markets a wide range of products for commercial applications, the majority of which are sold into the enterprise computing, communications, high-end consumer and industrial end-markets.

Enterprise Computing: datacenters, passive optical networks, desktops, notebooks, servers, monitors, printers and other computer peripherals.

Communications: base stations, optical networks, carrier networks, switches and routers, cable modems, wireless LAN and other communication infrastructure equipment.

High-End Consumer: handheld products, smartphones, wireless charging, set-top boxes, digital televisions, monitors and displays, tablets, wearables, digital video recorders and other consumer equipment.

Industrial: analog and digital video broadcast equipment, Video-over-IP solutions, automated meter reading, Internet of Things ("IoT"), smart grid, wireless charging, military and aerospace, medical, security systems, automotive, industrial and home automation and other industrial equipment.

Fiscal Year

The Company reports results on the basis of 52 and 53 week periods and ends its fiscal year on the last Sunday in January. The other quarters generally end on the last Sunday of April, July and October. All quarters consist of 13 weeks except for one 14-week period in the fourth quarter of 53-week years. The second quarter of fiscal years 2019 and 2018 each consisted of 13 weeks.

Principles of Consolidation

The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company, in accordance with accounting principles generally accepted in the United States ("GAAP") and on the same basis as the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended January 28, 2018. In the opinion of the Company, these interim unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, the financial position of the Company for the interim periods presented. All intercompany balances have been eliminated. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the interim unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete set of consolidated financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended January 28, 2018. The results reported in these interim unaudited condensed consolidated financial statements should not be regarded as indicative of results that may be expected for any subsequent period or for the entire year.

The Company’s interim unaudited condensed consolidated statements of income are referred to herein as the "Statements of Income." The Company’s interim unaudited condensed consolidated balance sheets are referred to herein as the "Balance Sheets" and interim unaudited condensed consolidated statements of cash flows as the "Statements of Cash Flows."

Segment Information

The Company’s Chief Executive Officer ("CEO") has been identified as the Chief Operating Decision Maker ("CODM") as defined by guidance regarding segment disclosures (see Note 12 for further discussion). Prior to the first quarter of fiscal year 2019, the Company had four operating segments. Beginning with the first quarter of fiscal year 2019, the Company identified three operating segments that aggregate into one reportable segment, the Semiconductor Products Group.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates.

Acquisitions

On May 2, 2018, the Company acquired substantially all the assets of IC Interconnect, Inc. (“ICI”) for a cash payment of approximately $7.3 million. The addition of ICI is aimed at further enhancing the Company’s U.S. research and development capabilities for its next-generation Z-Pak platform. $4.8 million was attributed to goodwill and $2.5 million was attributed to the estimated fair values of the tangible net assets acquired. The goodwill is deductible for tax purposes. The transaction was accounted for as a business combination and we are still assessing the purchase price allocation.

Net revenues, earnings and pro forma results of operations have not been presented because they are not material to the Company’s consolidated financial statements.

Settlements

On August 1, 2018, the Company announced the settlement of a lawsuit filed against HiLight Semiconductor Limited and related individual Defendants in accordance with which Semtech is to be paid approximately $9.0 million to cover damages for claims, costs and attorneys' fees. The $6.6 million received during the second quarter of fiscal year 2019 is presented within selling, general and administrative ("SG&A").

Recent Accounting Standards Adopted

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification ("ASC") 606), which requires an entity to recognize revenue from the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance addresses, in particular, contracts with more than one performance obligation, as well as the accounting for some costs to obtain or fulfill a contract with a customer, and provides for additional disclosures with respect to revenues and cash flows arising from contracts with customers.

The Company adopted the standard, effective January 29, 2018, using the modified retrospective transition method which resulted in an adjustment to retained earnings for the cumulative effect of applying the standard to all contracts not completed as of the adoption date. The primary change associated with the adoption relates to the Company’s sales to distributors with return or price adjustment rights where the Company will no longer defer revenue until the resale by the distributor to the end customer, but rather, will record revenue at the time control transfers to the distributor. The Company estimated the effects of returns and allowances provided to these distributors. Upon adoption, including the effect of income taxes, opening retained earnings as of January 29, 2018 increased by $11.1 million net, as a result of these changes. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Asset Transfers Other Than Inventory (Topic 740). This accounting standard update is aimed at recognizing the income tax consequences of intra-entity transfers of assets other than inventory when they occur. This removes the exception to postpone the recognition of income tax consequences of intra-entity transfers until the asset has been sold to an outside party. In the first quarter of 2019, the Company adopted ASU 2016-16 using a modified retrospective transition method, resulting in a $1.8 million decrease in retained earnings, a $3.7 million net increase in deferred income tax assets, and a $5.5 million decrease in pre-paid taxes.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The primary purpose of this ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic.

Accounting Guidance Issued but Not Adopted as of July 29, 2018

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require that substantially all leases be recognized by lessees on their balance sheets as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. Public entities are required to apply the amendments for annual periods beginning after December 15, 2018 and for interim periods within those annual periods. The Company will adopt this update beginning in the first quarter of fiscal year 2020 utilizing the modified retrospective transition method by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to elect certain practical expedients permitted under the transition guidance within the standard.

The Company expects the valuation of right of use assets and lease liabilities, previously described as operating leases, to be the present value of the Company’s forecasted future lease commitments. The Company is continuing to assess the overall impacts of the new standard, including the discount rate to be applied in these valuations, and expects the amendments will have a material impact on our consolidated financial statements, primarily to the consolidated balance sheets and related disclosures.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

The Company derives its revenue primarily from the sale of semiconductor products into various end markets. Revenue is recognized when control of these products is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for these products. Control is generally transferred when products are shipped and, to a lesser extent, when the products are delivered. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed and are reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts. The Company includes revenue related to granted technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of its recurring ordinary business.

The Company determines revenue recognition through the following five steps:

• Identification of the contract, or contracts, with a customer

• Identification of the performance obligations in the contract

• Determination of the transaction price

• Allocation of the transaction price to the performance obligations in the contract

• Recognition of revenue when, or as, performance obligations are satisfied

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

The Company’s revenue contracts generally represent a single performance obligation to sell its products to trade customers. Net sales reflect the transaction prices for contracts, which include units shipped at selling prices reduced by variable consideration. Determination of variable consideration requires judgment by the Company. Variable consideration includes expected sales returns and other price adjustments. Variable consideration is estimated using the expected value method considering all reasonably available information, including the Company’s historical experience and its current expectations, and is reflected in the transaction price when sales are recorded. Sales returns are generally accepted at the Company’s discretion or from distributors with such rights. The Company’s contracts with trade customers do not have significant financing components or non-cash consideration. The Company records net sales excluding taxes collected on its sales to its trade customers.

The Company provides an assurance type warranty which is typically not sold separately and does not represent a separate performance obligation. The Company’s payment terms are generally aligned with shipping terms.

The following presents the amounts by which financial statement line items were affected in the current periods due to the adoption of ASC 606 as compared with the guidance that was in effect before the change:

	Three Months Ended		Six Months Ended
Statements of Income	July 29, 2018		July 29, 2018
(in thousands, except per share amounts)	Increase/(decrease)		Increase/(decrease)

Diluted	0.02		0.06

Balance Sheets	July 29, 2018
(in thousands)	Increase/(decrease)
Deferred revenue	(17,306	)

Excludes line items that were not materially affected by the Company's adoption of ASC 606. The adoption had no impact to total net cash provided by or used in operating, investing or financing activities in the Statements of Cash Flows.

Contract Modifications:

If a contract is modified, which does not normally occur, changes in contract specifications and requirements must be accounted for. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are to distributor agreements for adding new goods or services that are considered distinct from the existing contract and the change in contract price reflects the standalone selling price of the distinct service.

Disaggregated Revenue:

The Company disaggregates revenue from contracts with customers by types of products and geography, as it believes it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Refer to “Note 12: Segment Information” for further information on revenues by product line and geographic region.

Contract Balances:

Accounts receivable represents the Company’s unconditional right to receive consideration from its customers. Contract assets consist of the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditioned on something other than the passage of time. ASC 606 also requires an entity to present a revenue contract as a contract liability in instances when a customer pays consideration, or an entity has a right to an amount of consideration that is unconditional (e.g. receivable), before the entity transfers a good or service to the customer. The opening and closing contract asset and contract liability balances are not material.

There were no impairment losses recognized on the Company’s accounts receivable or contract assets during the three and six months ended July 29, 2018. There were no significant changes in the contract assets or the contract liabilities for the three and six months ended July 29, 2018.

Practical Expedients:

Unsatisfied Performance Obligations: Because all of the Company’s performance obligations relate to contracts with a duration of less than one year, the Company elected to apply the optional exemption provided in ASC 606 and, therefore, is not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.

Contract Costs: All incremental customer contract acquisition costs are expensed as they are incurred as the amortization period of the asset that the Company otherwise would have recognized is one year or less in duration.

Significant Financing Component: The Company does not adjust the promised amount of consideration for the effects of a significant financing component as the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

Sales Tax Exclusion from the Transaction Price: The Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from the customer.

Shipping and Handling Activities: The Company accounts for shipping and handling activities performed after a customer obtains control of the good as activities to fulfill the promise to transfer the good.

Warrant. On October 5, 2016, the Company issued a warrant (the "Warrant") to Comcast Cable Communications Management LLC ("Comcast") to purchase up to 1,086,957 shares (the "Warrant Shares") of the common stock of Semtech Corporation. The Warrant was issued by the Company to Comcast in connection with an agreement between the parties regarding the intended trial deployment by Comcast of a low-power wide-area network ("LPWAN") in the United States, based on the Company’s LoRa® devices and wireless radio frequency technology. The Warrant was accounted for as equity and the cost was recognized as an offset to net sales over the respective performance period. The Warrant consisted of five performance tranches. The cost associated with each tranche had been recognized based on the fair value at each reporting date until vesting which was the measurement date. On April 27, 2018, the Company accelerated the vesting of the remaining 586,956 unvested shares from the Warrant, resulting in the full recognition of the remaining costs to be recognized for the Warrant. For the six month period ended July 29, 2018, the revenue offset reflects the cost associated with the Warrant of $21.5 million, including $15.9 million, related to the acceleration. The Warrant is now fully-vested and exercisable for a total of 869,565 shares, with no additional costs to be recognized in future periods.

Performance-Based Restricted Stock Units. The Company grants performance-based restricted stock units to select employees. The performance-based restricted stock units are valued as of the measurement date and expense is recognized on a straight line basis for the awards expected to vest based on the probability of attainment of the performance condition for each separately vesting portion of the award.

In the first quarter of fiscal year 2019, the Company granted 200,442 performance-based restricted stock units that have a pre-defined market condition and a service condition that are accounted for as equity awards. The market condition is determined based upon the Company’s total stockholder return ("TSR") benchmarked against the TSR of the S&P SPDR Semiconductor ETF (NYSE:XSD) over a one, two and three year period (one-third of the awards vesting each performance period). The fiscal year 2019 award recipients must be employed for the entire performance period and be an active employee at the time of vesting of the awards. The Company used a Monte Carlo simulation to determine the grant-date fair value for these awards, which takes into consideration the possible outcomes pertaining to the TSR market condition. The grant-date fair value per unit of the awards granted in the first quarter of fiscal year 2019 for each one, two and three year performance period is $33.02, $34.85 and $36.52, respectively.

Award Modifications. In the first quarter of fiscal year 2019, the Company modified the terms of 159,000 fully vested shares held by 8 employees. As a result of the modification, additional compensation cost of $2.8 million was recognized during the first quarter of fiscal year 2019.

Instruments Measured at Fair Value on a Recurring Basis

Financial assets and liabilities measured and recorded at fair value on a recurring basis were presented within the Company's Balance Sheets as follows:

Total financial liabilities	$	20,894	$	—	$	126	$	20,768	$	21,668	$	—	$	—	$	21,668

During the six months ended July 29, 2018, the Company had no transfers of financial assets or liabilities between Level 1, Level 2 or Level 3. As of July 29, 2018 and January 28, 2018, the Company had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.

The fair values of the foreign exchange forward contracts are valued using Level 2 inputs. Foreign currency forward contracts are valued using readily available foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to the present value. Contracts in a gain position are recorded in the Balance Sheets within the caption "Other current assets" and the value of contracts in a loss position are recorded within the caption "Accrued liabilities" within the Balance Sheets. Please see Note 15 for further discussion of the Company’s derivative instruments.

The convertible debt is valued using probability weighted cash flows (Level 3 inputs).

The AptoVision Earn-out liability is valued utilizing estimates of annual revenue, adjusted earnings and product development targets (Level 3 inputs) through July 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Cycleo Earn-out liability (see Note 11) is valued utilizing estimates of annual revenue and operating income (Level 3 inputs) through April 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Company measures contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liabilities will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. For the Cycleo Earn-out and AptoVision Earn-out, these companies have business profiles comparable to a start-up company. Accordingly, their respective revenue projections are subject to significant revisions. This characteristic can result in volatile changes to the measurement of fair value for a given earn-out.

The Company reviews and re-assesses the estimated fair value of contingent consideration on a recurring basis, and the updated fair value could differ materially from the previous estimates. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

A reconciliation of the change in the earn-out liability during the six months ended July 29, 2018 is as follows:

(in thousands)	AptoVision			Cycleo		Total
Balance at January 28, 2018	$	21,000		$	668	$	21,668
Changes in the fair value of contingent earn-out obligations	(900		)	—		(900		)
Balance as of July 29, 2018	$	20,100		$	668	$	20,768

Instruments Not Recorded at Fair Value on a Recurring Basis

Some of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents including money market deposits, net receivables, certain other assets, accounts payable, accrued expenses, accrued personnel costs, and other current liabilities.

The Company’s long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes. The fair value of the Company’s Term Loans (as defined in Note 9) is $123.8 million and $131.3 million as of July 29, 2018 and January 28, 2018, respectively. The fair value of the Company's Revolving Commitments (as defined in Note 9) is$97.0 million as of both July 29, 2018 and January 28, 2018, respectively. These are based on Level 2 inputs which are derived from transactions with similar amounts, maturities, credit ratings and payment terms.

Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis

The Company reduces the carrying amounts of its goodwill, intangible assets, long-lived assets and non-marketable equity securities to fair value when held for sale or determined to be impaired.

For its investment in non-marketable equity interests, the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of its equity investments during the first six months of fiscal year 2019.

Balance at July 29, 2018	$	274,085	$	67,812	$	4,834	$	346,731

As a result of the realignment of its operating segments, during the first quarter of fiscal year 2019, the Company combined the Wireless and Sensing and the Power and High-Reliability reporting units (see Note 12). Goodwill of $49.4 million related to the Power and High-Reliability reporting unit which was previously a separate reporting unit is now included in the Wireless and Sensing reporting unit’s goodwill balance. The reporting units are the same as the operating segments which are part of a single reportable segment. The difference between the fair value and the carrying amount of these reporting units is one of several factors the Company will consider before reaching its conclusion about whether to perform the first step of the goodwill impairment test.

Income Taxes

Income Taxes

The Company’s effective tax rate differs from the statutory federal income tax rate of 21% primarily due to regional mix of income and a partial release of the valuation allowance in the U.S. The valuation allowance was released in the first quarter of fiscal year 2019 as a result of the Company obtaining the information necessary to evaluate the impact of the Global Intangible Low-Taxed Income (“GILTI”) provisions, enacted as part of the Tax Cuts and Jobs Act (“Tax Act”) on December 22, 2017. This item was left open under Staff Accounting Bulletin 118 (“SAB 118”) in the financial statements for the year ended January 28, 2018 and the Company has now made a reasonable estimate based on the most current information available.

The Tax Act made significant changes to U.S. income tax laws, including transitioning from a worldwide tax system to a territorial tax system. This change in the U.S. international tax system included the introduction of several new tax regimes that are effective as of January 1, 2018, including the GILTI provisions. The GILTI provisions effectively tax the foreign earnings of U.S. multinational companies at 10.5%, half the current corporate tax rate. During the three months ended April 29, 2018, the Company finalized its analysis regarding the interplay of the foreign tax credits associated with this income, which are allowed against the U.S. tax liability generated as a result of the GILTI provision, and the potential impact on the related valuation allowance. As a result, the Company recorded a tax benefit of $15.8 million during the first quarter of fiscal year 2019 related to the reduction of the valuation allowance on certain U.S. deferred tax assets generated prior to fiscal year 2019.

While management believes the provisional amounts recorded during the six months ended July 29, 2018 and the year ended January 28, 2018 represent reasonable estimates of the ultimate impact U.S. tax reform will have on the Company's consolidated financial statements, it is possible the Company may continue to materially adjust these amounts for related administrative guidance, notices, implementation regulations, potential legislative amendments and interpretations as the Tax Act continues to evolve. These adjustments could have an impact on the Company's Balance Sheets and Statements of Income.

The Company uses a two-step approach to recognize and measure uncertain tax positions ("UTP"). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. 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.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (before the federal impact of state items) is as follows:

(in thousands)
Balance at January 28, 2018	$	16,059
Additions based on tax positions related to the current year	855
Balance as of July 29, 2018	$	16,914

Included in the balance of gross unrecognized tax benefits at July 29, 2018 and January 28, 2018, are $4.7 million and $3.9 million, respectively, of net tax benefits (after federal impact of state items), that, if recognized, would impact the effective tax rate, prior to consideration of any required valuation allowance.

The liability for UTP is reflected within the Balance Sheets as follows:        

(in thousands)	July 29, 2018		January 28, 2018
Deferred tax assets - non-current	$	12,236	$	12,135
Other long-term liabilities	4,678		3,924
Total accrued taxes	$	16,914	$	16,059

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits within the "Provision for taxes" in the Statements of Income.

Tax years prior to 2013 (the Company’s fiscal year 2014) are generally not subject to examination by the U.S. Internal Revenue Service ("IRS") except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. For state returns, the Company is generally not subject to income tax examinations for calendar years prior to 2012 (the Company’s fiscal year 2013). The Company has a significant tax presence in Switzerland for which Swiss tax filings have been examined through fiscal year 2017. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.

The Company’s regional income from continuing operations before taxes and equity in net losses of equity method investments is as follows:

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingencies

Commitments and Contingencies

In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. The Company also discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued, and makes adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount. The Company may be unable to estimate a possible loss or range of possible loss due to various reasons, including, among others: (i) if the damages sought are indeterminate; (ii) if the proceedings are in early stages, (iii) if there is uncertainty as to the outcome of pending appeals, motions or settlements, (iv) if there are significant factual issues to be determined or resolved, and (v) if there are novel or unsettled legal theories presented. In such instances, there is considerable uncertainty regarding the ultimate resolution of such matters, including a possible eventual loss, if any.

Because the outcomes of litigation and other legal matters are inherently unpredictable, the Company’s evaluation of legal matters or proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved matters and proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. However, legal matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond the Company’s control.

As such, even though the Company intends to vigorously defend itself with respect to its legal matters, there can be no assurance that the final outcome of these matters will not materially and adversely affect the Company’s business, financial condition, operating results, or cash flows.

From time to time, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to IP, contract, product liability, employment, and environmental matters. In the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole.

The Company’s currently pending legal matters of note are discussed below:

Environmental Matters

The Company vacated a former facility in Newbury Park, California in 2002, but continues to address groundwater and soil contamination at the site.

The Company’s efforts to address site conditions have been at the direction of the Los Angeles Regional Water Quality Control Board (“RWQCB”). In October 2013, an order was issued including a scope of proposed additional site work, monitoring, and proposed remediation activities. The Company filed appeals of the October 2013 order seeking reconsideration by the RWQCB and review by the State Water Resources Control Board ("SWRCB") of the removal of two other potentially responsible parties, and seeking clarification of certain other factual findings. In April 2015, the RWQCB denied the Company’s request to name the two other potentially responsible parties to the order, but did correct certain findings of fact identified by the Company in its petition for reconsideration. The SWRCB has not yet ruled on the Company’s petition for review of the RWQCB’s action as the petition was filed with a request it be held in abeyance.

The Company has been complying with RWQCB orders and direction, and is implementing an approved remedial action plan (prepared by an environmental firm retained by the Company) addressing the cleanup of soil, groundwater, and soil vapor at the site.

The Company has accrued liabilities where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. Based on the latest determinations by the RWQCB and the most recent actions taken pursuant to the remedial action plan, the Company continues to estimate the range of probable loss between $3.6 million and $7.2 million.Given the uncertainties associated with environmental assessment and the remediation activities, the Company is unable to determine a best estimate within the range of loss. Therefore, the Company has recorded the minimum amount of probable loss. These estimates could change as a result of changes in planned remedial actions, further actions from the regulatory agency, remediation technology, and other factors.

Indemnification

The Company has entered into agreements with its current and former executives and directors indemnifying them against certain liabilities incurred in connection with the performance of their duties. The Company’s Certificate of Incorporation and Bylaws contain comparable indemnification obligations with respect to the Company’s current directors and employees.

Product Warranties

The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances the Company has agreed to other or additional warranty terms, including indemnification provisions.

The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense has been immaterial to the Company’s consolidated financial statements.

Earn-out Liability

Pursuant to the terms of the amended earn-out arrangement ("Cycleo Earn-out") with the former shareholders of Cycleo SAS ("Cycleo Earn-out Beneficiaries"), which the Company acquired on March 7, 2012, the Company potentially may make payments totaling up to approximately $16.0 million based on the achievement of a combination of certain revenue and operating income milestones over a defined period ("Cycleo Defined Earn-out Period"). The Cycleo Defined Earn-out Period covers the period April 27, 2015 to April 26, 2020. For certain of the Cycleo Earn-out Beneficiaries, payment of the earn-out liability is contingent upon continued employment and is accounted for as post-acquisition compensation expense over the service period. The portion of the earn-out liability that is not dependent on continued employment is not considered as compensation expense. The Company has recorded a liability for the Cycleo Earn-out of $6.1 million and $5.5 million as of July 29, 2018 and January 28, 2018, respectively, of which $2.2 million is expected to be paid within twelve months.

Pursuant to the terms of the AptoVision Earn-out ("AptoVision Earn-out") with the former shareholders of AptoVision ("AptoVision Earn-out Beneficiaries"), which the Company acquired on July 1, 2017, the Company potentially may make payments totaling up to approximately $47.0 million based on the achievement of a combination of certain net revenue, adjusted earnings and product development targets measured from the acquisition date through July 26, 2020.

A summary of earn-out liabilities, included in "Accrued liabilities" and "Other long-term liabilities", by classification follows:

Segment Information

Segment Information

Segment Information

The Company’s CEO functions as the CODM. The Company’s CODM makes operating decisions and assesses performance based on these operating segments. As part of a realignment strategy, during the first quarter of fiscal year 2019, the Company restructured and combined the Power and High Reliability operating segment with the Wireless and Sensing operating segment to better align resources with our LoRa® initiatives. This resulted in the Company having three operating segments compared to previously having four operating segments. The three operating segments: Protection, Signal Integrity, and Wireless and Sensing, all have similar economic characteristics and have been aggregated into one reportable segment identified in the table below as the "Semiconductor Products Group".

The Company’s assets are commingled among the various operating segments and the CODM does not use that information in making operating decisions or assessing performance. Therefore, the Company has not included asset information by segment below.

Net sales by segment are as follows:

Derivative Instruments and Hedging Activities

Derivatives and Hedging Activities

The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company uses derivative financial instruments in the form of forward contracts to mitigate risk associated with adverse movements in these foreign currency exchange rates on a portion of foreign denominated expenses expected to be realized during the current and following fiscal year. Currency forward contracts involve fixing the exchange rate for delivery of a specified amount of foreign currency on a specified date.

The Company’s accounting treatment for these instruments is based on whether or not the instruments are designated as a hedging instrument. The Company is currently applying hedge accounting to all foreign currency derivatives and has designated these hedges as cash flow hedges.

At July 29, 2018, the Company had the following outstanding foreign exchange contracts:

(in thousands)
Foreign Exchange Contracts	Number of Instruments	Sell Notional Value		Buy Notional Value
Sell USD/Buy CAD Forward Contract	6	$	8,560	C$	11,000
Total	6

These contracts met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of "Accumulated other comprehensive loss" within the Balance Sheet. The effective portions of cash flow hedges are recorded in accumulated other comprehensive income or loss ("AOCI") until the hedged item is recognized in SG&A expense within the Statements of Income when the underlying hedged expense is recognized. Any ineffective portions of cash flow hedges are recorded in "Non-operating expense, net" within the Company’s Statements of Income. The Company presents its derivative assets and liabilities at their gross fair values on the Balance Sheets.

The Company had no outstanding foreign exchange contracts at January 28, 2018. The table below summarizes the carrying values of derivative instruments as of July 29, 2018:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Fiscal Year

Fiscal Year

The Company reports results on the basis of 52 and 53 week periods and ends its fiscal year on the last Sunday in January. The other quarters generally end on the last Sunday of April, July and October. All quarters consist of 13 weeks except for one 14-week period in the fourth quarter of 53-week years. The second quarter of fiscal years 2019 and 2018 each consisted of 13 weeks.

Principles of Consolidation

Principles of Consolidation

The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company, in accordance with accounting principles generally accepted in the United States ("GAAP") and on the same basis as the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended January 28, 2018. In the opinion of the Company, these interim unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, the financial position of the Company for the interim periods presented. All intercompany balances have been eliminated. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the interim unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete set of consolidated financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended January 28, 2018. The results reported in these interim unaudited condensed consolidated financial statements should not be regarded as indicative of results that may be expected for any subsequent period or for the entire year.

The Company’s interim unaudited condensed consolidated statements of income are referred to herein as the "Statements of Income." The Company’s interim unaudited condensed consolidated balance sheets are referred to herein as the "Balance Sheets" and interim unaudited condensed consolidated statements of cash flows as the "Statements of Cash Flows.

Segment Information

Segment Information

The Company’s Chief Executive Officer ("CEO") has been identified as the Chief Operating Decision Maker ("CODM") as defined by guidance regarding segment disclosures (see Note 12 for further discussion). Prior to the first quarter of fiscal year 2019, the Company had four operating segments. Beginning with the first quarter of fiscal year 2019, the Company identified three operating segments that aggregate into one reportable segment, the Semiconductor Products Group.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates.

Recent Accounting Pronouncements

Recent Accounting Standards Adopted

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification ("ASC") 606), which requires an entity to recognize revenue from the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance addresses, in particular, contracts with more than one performance obligation, as well as the accounting for some costs to obtain or fulfill a contract with a customer, and provides for additional disclosures with respect to revenues and cash flows arising from contracts with customers.

The Company adopted the standard, effective January 29, 2018, using the modified retrospective transition method which resulted in an adjustment to retained earnings for the cumulative effect of applying the standard to all contracts not completed as of the adoption date. The primary change associated with the adoption relates to the Company’s sales to distributors with return or price adjustment rights where the Company will no longer defer revenue until the resale by the distributor to the end customer, but rather, will record revenue at the time control transfers to the distributor. The Company estimated the effects of returns and allowances provided to these distributors. Upon adoption, including the effect of income taxes, opening retained earnings as of January 29, 2018 increased by $11.1 million net, as a result of these changes. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Asset Transfers Other Than Inventory (Topic 740). This accounting standard update is aimed at recognizing the income tax consequences of intra-entity transfers of assets other than inventory when they occur. This removes the exception to postpone the recognition of income tax consequences of intra-entity transfers until the asset has been sold to an outside party. In the first quarter of 2019, the Company adopted ASU 2016-16 using a modified retrospective transition method, resulting in a $1.8 million decrease in retained earnings, a $3.7 million net increase in deferred income tax assets, and a $5.5 million decrease in pre-paid taxes.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The primary purpose of this ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic.

Accounting Guidance Issued but Not Adopted as of July 29, 2018

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require that substantially all leases be recognized by lessees on their balance sheets as a right-of-use asset and corresponding lease liability, including leases currently accounted for as operating leases. Public entities are required to apply the amendments for annual periods beginning after December 15, 2018 and for interim periods within those annual periods. The Company will adopt this update beginning in the first quarter of fiscal year 2020 utilizing the modified retrospective transition method by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to elect certain practical expedients permitted under the transition guidance within the standard.

Earnings Per Share

Basic earnings per common share is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings per common share incorporates the incremental shares issuable, calculated using the treasury stock method, upon the assumed exercise of non-qualified stock options, the vesting of restricted stock units and performance unit awards if the conditions have been met.

Share-based Compensation, Warrant

The Warrant was issued by the Company to Comcast in connection with an agreement between the parties regarding the intended trial deployment by Comcast of a low-power wide-area network ("LPWAN") in the United States, based on the Company’s LoRa® devices and wireless radio frequency technology. The Warrant was accounted for as equity and the cost was recognized as an offset to net sales over the respective performance period. The Warrant consisted of five performance tranches. The cost associated with each tranche had been recognized based on the fair value at each reporting date until vesting which was the measurement date.

Share-based Compensation, Performance-based RSUs

The Company grants performance-based restricted stock units to select employees. The performance-based restricted stock units are valued as of the measurement date and expense is recognized on a straight line basis for the awards expected to vest based on the probability of attainment of the performance condition for each separately vesting portion of the award.

Fair Value of Financial Instruments

Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis

The Company reduces the carrying amounts of its goodwill, intangible assets, long-lived assets and non-marketable equity securities to fair value when held for sale or determined to be impaired.

Instruments Not Recorded at Fair Value on a Recurring Basis

Some of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents including money market deposits, net receivables, certain other assets, accounts payable, accrued expenses, accrued personnel costs, and other current liabilities.

The Company’s long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes.

As of July 29, 2018 and January 28, 2018, the Company had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.

The fair values of the foreign exchange forward contracts are valued using Level 2 inputs. Foreign currency forward contracts are valued using readily available foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to the present value. Contracts in a gain position are recorded in the Balance Sheets within the caption "Other current assets" and the value of contracts in a loss position are recorded within the caption "Accrued liabilities" within the Balance Sheets. Please see Note 15 for further discussion of the Company’s derivative instruments.

The convertible debt is valued using probability weighted cash flows (Level 3 inputs).

The AptoVision Earn-out liability is valued utilizing estimates of annual revenue, adjusted earnings and product development targets (Level 3 inputs) through July 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Cycleo Earn-out liability (see Note 11) is valued utilizing estimates of annual revenue and operating income (Level 3 inputs) through April 2020. These estimates represent inputs for which market data are not available and are developed using the best information available about the assumptions that market participants would use when pricing the liability.

The Company measures contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a Monte Carlo valuation method as a valuation technique to determine the value of the earn-out liability. The significant unobservable inputs used in the fair value measurements are revenue projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liabilities will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. For the Cycleo Earn-out and AptoVision Earn-out, these companies have business profiles comparable to a start-up company. Accordingly, their respective revenue projections are subject to significant revisions. This characteristic can result in volatile changes to the measurement of fair value for a given earn-out.

The Company reviews and re-assesses the estimated fair value of contingent consideration on a recurring basis, and the updated fair value could differ materially from the previous estimates. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

Inventory

Inventories, consisting of material, material overhead, labor, and manufacturing overhead, are stated at the lower of cost (first-in, first-out) or market

Interest and Penalties on Unrecognized Tax Benefits

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits within the "Provision for taxes" in the Statements of Income.

Commitments and Contingencies

In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. The Company also discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued, and makes adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount. The Company may be unable to estimate a possible loss or range of possible loss due to various reasons, including, among others: (i) if the damages sought are indeterminate; (ii) if the proceedings are in early stages, (iii) if there is uncertainty as to the outcome of pending appeals, motions or settlements, (iv) if there are significant factual issues to be determined or resolved, and (v) if there are novel or unsettled legal theories presented. In such instances, there is considerable uncertainty regarding the ultimate resolution of such matters, including a possible eventual loss, if any.

Because the outcomes of litigation and other legal matters are inherently unpredictable, the Company’s evaluation of legal matters or proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved matters and proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. However, legal matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond the Company’s control.

Product Warranties

Product Warranties

The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances the Company has agreed to other or additional warranty terms, including indemnification provisions.

The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense has been immaterial to the Company’s consolidated financial statements.

Derivatives

The Company’s accounting treatment for these instruments is based on whether or not the instruments are designated as a hedging instrument. The Company is currently applying hedge accounting to all foreign currency derivatives and has designated these hedges as cash flow hedges.

These contracts met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of "Accumulated other comprehensive loss" within the Balance Sheet. The effective portions of cash flow hedges are recorded in accumulated other comprehensive income or loss ("AOCI") until the hedged item is recognized in SG&A expense within the Statements of Income when the underlying hedged expense is recognized. Any ineffective portions of cash flow hedges are recorded in "Non-operating expense, net" within the Company’s Statements of Income. The Company presents its derivative assets and liabilities at their gross fair values on the Balance Sheets.

Revenue

The Company derives its revenue primarily from the sale of semiconductor products into various end markets. Revenue is recognized when control of these products is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for these products. Control is generally transferred when products are shipped and, to a lesser extent, when the products are delivered. Recovery of costs associated with product design and engineering services are recognized during the period in which services are performed and are reported as a reduction to product development and engineering expense. Historically, these recoveries have not exceeded the cost of the related development efforts. The Company includes revenue related to granted technology licenses as part of "Net sales." Historically, revenue from these arrangements has not been significant though it is part of its recurring ordinary business.

The Company determines revenue recognition through the following five steps:

• Identification of the contract, or contracts, with a customer

• Identification of the performance obligations in the contract

• Determination of the transaction price

• Allocation of the transaction price to the performance obligations in the contract

• Recognition of revenue when, or as, performance obligations are satisfied

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

The Company’s revenue contracts generally represent a single performance obligation to sell its products to trade customers. Net sales reflect the transaction prices for contracts, which include units shipped at selling prices reduced by variable consideration. Determination of variable consideration requires judgment by the Company. Variable consideration includes expected sales returns and other price adjustments. Variable consideration is estimated using the expected value method considering all reasonably available information, including the Company’s historical experience and its current expectations, and is reflected in the transaction price when sales are recorded. Sales returns are generally accepted at the Company’s discretion or from distributors with such rights. The Company’s contracts with trade customers do not have significant financing components or non-cash consideration. The Company records net sales excluding taxes collected on its sales to its trade customers.

The Company provides an assurance type warranty which is typically not sold separately and does not represent a separate performance obligation. The Company’s payment terms are generally aligned with shipping terms.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Objectives for using derivative instruments	The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company uses derivative financial instruments in the form of forward contracts to mitigate risk associated with adverse movements in these foreign currency exchange rates on a portion of foreign denominated expenses expected to be realized during the current and following fiscal year.
Period over which any gains or losses under foreign exchange contracts are expected to be realized	12 months
Cash flow hedge losses expected to be reclassified into earnings within twelve months	$ 0.2
