Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Summary of Critical Accounting Policies

Note 1. Basis of Presentation

Daktronics, Inc. and its subsidiaries (the “Company”, “Daktronics”, “we”, “our”, or “us”) are the world's industry leader in designing and manufacturing electronic scoreboards, programmable display systems and large screen video displays for sporting, commercial and transportation applications.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions affecting the reported amounts therein. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The balance sheet at April 28, 2018, has been derived from the audited financial statements at that date, but it does not include all the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with our financial statements and notes thereto for the year ended April 28, 2018, which are contained in our Annual Report on Form 10-K previously filed with the Securities and Exchange Commission ("SEC"). The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year.

Certain prior year amounts in the condensed consolidated balance sheet have been reclassified to conform to the current year's presentation due to the adoption of Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). Billings in excess of costs and estimated earnings, customer deposits, and deferred revenue are combined to present contract liabilities. Costs and estimated earnings in excess of billings now represent contract assets. These reclassifications had no effect on reported net income, comprehensive income, cash flows, total assets or total liabilities.

Daktronics, Inc. operates on a 52- or 53-week fiscal year, with our fiscal year ending on the Saturday closest to April 30 of each year. When April 30 falls on a Wednesday, the fiscal year ends on the preceding Saturday. Within each fiscal year, each quarter is comprised of 13-week periods following the beginning of each fiscal year. In each 53-week year, an additional week is added to the first quarter, and each of the last three quarters is comprised of a 13-week period. The three months ended July 28, 2018 and July 29, 2017, contained operating results for 13 weeks.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheet that sum to total of the same amounts showing in the condensed consolidated statement of cash flows:



	July 28, 2018		July 29, 2017
Cash and cash equivalents	$	15,915	$	26,868
Restricted cash	26		222
Total cash, cash equivalents, and restricted cash shown in the condensed consolidated statement of cash flows	$	15,941	$	27,090

Recent Accounting Pronouncements

New Accounting Standards Adopted

In October 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-16, Income Taxes (Topic 740) Intra-Entity Transfers of Assets Other than Inventory, which is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party, which is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. This update eliminates the exception by requiring entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. We have adopted ASU 2016-16 during the first quarter of fiscal 2019. The adoption of ASU 2016-16 did not have an impact on our condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Subsequently, the FASB also issued ASUs 2016-08, 2016-10, 2016-12, and 2016-20 to give further guidance to revenue recognition matters. ASU 2014-09 and related guidance supersedes revenue recognition requirements under FASB Accounting Standards Codification ("ASC") Topic 605 and related industry specific revenue recognition guidance. This new standard defines a comprehensive revenue recognition model, requiring a company to recognize revenue from the transfer of goods or services to customers in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. It defines a five-step process to achieve this core principle and allows companies to use more judgment and make more estimates than under current guidance and requires additional disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the customer contracts. It provides guidance on transition requirements.

We have adopted ASU 2014-09 and its related guidance under the modified retrospective method during the first quarter of fiscal 2019 by applying the guidance to all open contracts at the adoption date. We have completed our evaluation of our revenue arrangements under the new standard and have assessed that the adoption did not materially change the timing or amount of revenue recognized, primarily based upon our assessment of "point in time" and "over time" revenue recognition. No adjustment to beginning retained earnings was recorded, and we have made additional disclosures related to revenue from contracts with customers as required by the new standard upon adoption. See "Note 4. Revenue Recognition" for more information.

New Accounting Standards Not Yet Adopted

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate under the U.S. Tax Cuts and Jobs Act (the "Tax Act"). ASU 2018-02 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted that can be made on a prospective or retrospective basis. We are currently evaluating the effect that adopting ASU 2018-02 will have on our condensed consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. A goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for interim and annual periods beginning after December 15, 2019 and will require adoption on a prospective basis. We are currently evaluating the effect that adopting ASU 2017-04 will have on our condensed consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides guidance regarding the measurement and recognition of credit impairment for certain financial assets. ASU 2016-13 is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted, and will require adoption on a modified retrospective basis. We are currently evaluating the effect that adopting ASU 2016-13 will have on our condensed consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (that is, lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. ASU 2016-02 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 (Leases), and ASU 2018-11, Leases (Topic 842), Targeted Improvements, which provide (i) narrow amendments to clarify how to apply certain aspects of the new lease standard, (ii) entities with an additional transition method to adopt the new standard, and (ii) lessors with a practical expedient for separating components of a contract. All ASUs are effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and will require adoption on a modified retrospective basis. We are currently evaluating the effect that adopting these ASUs will have on our condensed consolidated financial statements and related disclosures.

Equity and Cost Method Investments [Abstract]
Cost and Equity Method Investments Disclosure [Text Block]	Note 2. Investments in Affiliates Investments in affiliates over which we have significant influence are accounted for under the equity method of accounting. Investments in affiliates over which we do not have the ability to exert significant influence over the affiliate's operating and financing activities are accounted for under the cost method of accounting. We have evaluated our relationships with our affiliates and have determined that these entities are not variable interest entities. The aggregate amount of investments accounted for under the equity method was $3,939 and $3,647 at July 28, 2018 and April 28, 2018, respectively. The equity method requires us to report our share of losses up to our equity investment amount. Cash paid for investments in affiliates is included in the "Purchases of equity investment" line item in our condensed consolidated statements of cash flows. Our proportional share of the respective affiliates' earnings or losses is included in the "Other (expense) income, net" line item in our condensed consolidated statements of operations. For the three months ended July 28, 2018 and July 29, 2017, our share of the losses of our affiliates was $134 and $85, respectively. The aggregate amount of investments accounted for under the cost method was $42 at July 28, 2018 and April 28, 2018, respectively. There have not been any identified events or changes in circumstances that may have a significant adverse effect on their fair value, and it is not practical to estimate their fair value.

Earnings Per Share [Abstract]

Earnings Per Share EPS

Note 3. Earnings Per Share ("EPS")

Basic EPS is computed by dividing income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution which may occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock which share in our earnings.

The following is a reconciliation of the net income and common share amounts used in the calculation of basic and diluted EPS for the three months ended July 28, 2018 and July 29, 2017:



	Net income		Shares	Per share income
For the three months ended July 28, 2018
Basic earnings per share	$	4,574	44,638	$	0.10
Dilution associated with stock compensation plans	—		193	—
Diluted earnings per share	$	4,574	44,831	$	0.10
For the three months ended July 29, 2017
Basic earnings per share	$	8,429	44,244	$	0.19
Dilution associated with stock compensation plans	—		217	—
Diluted earnings per share	$	8,429	44,461	$	0.19

Options outstanding to purchase 1,798 shares of common stock with a weighted average exercise price of $10.46 for the three months ended July 28, 2018 and 1,580 shares of common stock with a weighted average exercise price of $12.48 for the three months ended July 29, 2017 were not included in the computation of diluted earnings per share because the effects would be anti-dilutive.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Note 4. Revenue Recognition

Our accounting policies and estimates as a result of adopting ASU 2014-09, Revenue from Contracts with Customers (Topic 606) are as follows:

Net sales are reported net of estimated sales returns and discounts, include compensation from customers for shipping and handling, and exclude sales taxes.

We often contract some or all equipment and services to our customers under the terms of a bundled (performance obligation(s)) sales arrangement. Delivery of these performance obligations can be transferred over time or at a single point in time. At contract inception, we evaluate for material distinct goods and services using professional judgment. We conclude we have separate performance obligations for items capable of being distinct in the eyes of the customer and if the item is distinct within the context of the contract. For those warranties that extend beyond typical terms and include other services ("service-type warranty"), we account for them as a separate performance obligation. When separate performance obligations are identified, we allocate the consideration to the individual performance obligation based on the best evidence and method we judge as faithfully depicting the value of the performance obligation. We primarily use the cost plus a margin approach to allocate the consideration.

We estimate the arrangement's consideration to be the value we expect to be entitled to as a result of transferring the performance obligation to the customer. The sales price may include variable consideration and amounts related to subcontracted deliverables (i.e., we integrate the materials, labor and equipment into the deliverables promised to the customer). When we have a contract that has variable consideration, including discounts, claims, unpriced change orders, and liquidated damages, we estimate the amount of revenue using the expected value (i.e., the sum of the probability-weighted amount) or the most likely amount method, whichever is expected to better predict revenue. Factors considered in determining revenue associated with variable consideration include the following: (a) the contract or other evidence providing legal basis, (b) additional costs caused by unforeseen circumstances, (c) evidence supporting the claim, and (d) historical evidence and patterns of customers.

Our material performance obligation types include:

Unique configuration contracts: audio-visual communication systems uniquely configured (custom) or integrated for a customer's particular location and system configuration may include all or a combination of the following: engineering services, project management services, video display(s), control solution(s), installation and integration services, scoring and messaging equipment, training, other on-site services, spare parts, software licenses, and assurance-type warranties.

We account for these types of contracts as a combined single performance obligation with no segmentation between types of products and services. A single performance obligation is most appropriate in our judgment when the substantial part of our promise to customers is to integrate and incorporate individual goods and services into a combined output or system; often times the system is customized or significantly modified to the customers' desired configurations and location, and the interrelated goods and services provide utility to the customers as a package.

Revenue for uniquely configured (custom) or integrated systems are recognized over time as performance obligations are satisfied due to the continuous transfer of control to the customer. This transfer of control is evidenced either by the customer directing the work in process as demonstrated by contractual termination clauses or by our right to payment for work performed to date that does not have an alternative use to us. Sales and profits are recognized over time following the cost-to-cost input method (percentage-of-completion) measured by the percentage of costs incurred to date as compared to estimated total costs for each contract. The cost-to-cost input method is the most faithful depiction of our performance because it measures the value of the contract transferred to the customer. Costs to perform include direct and indirect costs for contract design, production, integration, installation, and assurance-type warranty reserve. Direct costs include material and components; manufacturing, project management, and engineering labor; and subcontracting expenses. Indirect costs include allocated charges for such items as facilities and equipment depreciation and general overhead. Provisions of estimated losses on uncompleted contracts are made in the period when such losses are capable of being estimated. Pre-contract costs are expensed as incurred unless they are expected to be recovered.

We receive payments from customers based on a billing schedule as established in our contracts. Billing schedules include down payments and progress billings over time or set milestone payments specific to the project. Variability in contract assets and contract liabilities ("Net over/under billings") relates to the timing of billings and revenue recognition, which can vary significantly depending on contractual payment terms and build and installation schedules. Balances are also impacted by the seasonality of the sports markets.

Contract modifications to existing contracts with customers are evaluated in accordance with the five-step revenue model. We treat contract modifications as a separate contract and new performance obligations when the additional goods or services are distinct and do not add to the unique configuration or are outside the integrated system and when the consideration reflects standalone selling prices. If the additional goods or services offered under the modification enhance the uniquely configured or integrated systems, revenue is allocated to the existing contracts' performance obligation. Modifications may cause changes in the timing of revenue recognition depending on the allocation to various performance obligations.

The time between contract order and project completion is typically less than 12 months but may extend longer depending on the amount of custom work and customers’ delivery needs.

Limited configuration (standard systems) and after-sale parts contracts: Revenue for limited configured (standard systems) or after-sale parts contracts with limited or no configuration or integration are recognized as individual performance obligations. Revenue is recognized at a point in time when title or control passes, or services are performed. Customers can purchase standard display systems individually or in large quantities. For purchases made in large quantities, we account for each piece of equipment separately as a distinct performance obligation from which a customer derives benefit. For systems with bundled standard products and services, much of the promised work for the customer is performed at the same time; therefore, allocation of the transaction price does not impact revenue timing. We account for these types of contracts as a combined single performance obligation with no segmentation between types of products and services. For those agreements we perform over reporting periods, we separate material performance obligations and allocate expected consideration. Immaterial goods or services in the context of the contract are included with the display system performance obligation. Standard systems and equipment with limited configurations or integrations may include all or a combination (when immaterial) of the following performance obligations: engineering services, project management services, video display(s), control solution(s), installation and integration services, scoring, messaging and audio equipment, training, spare parts, software licenses, assurance-type warranties, and after-sale parts. When fulfilling a limited configuration order, we are typically able to redirect the video displays or scoring, messaging, or audio equipment to another customer without incurring significant economic losses. Therefore, control is transferred to the customer at a point in time. For service-type or other performance obligations, we recognize revenue over time, which is the most faithful depiction of the customer obtaining control and benefits from the work performed.

Services and other: Services sold on a stand-alone basis or after the initial system sale include performance obligations such as event support, control room design, on-site training, equipment service, service-type warranties, technical support, software sold as a service, and other immaterial revenue streams. Services and other are recognized as net sales when the services are performed and control is transferred to the customer at a point in time or over time for time-based "stand ready to perform" type obligations. If we have the right to consideration from a customer that directly corresponds with the value of our performance (where we bill a fixed amount for each hour of service provided), we recognize revenue related to the work completed.

Software: Revenues from software license fees on sales, other than uniquely configured type contracts, are recognized when delivery of the product has occurred. Subscription-based licenses include the right for a customer to use our licenses and receive related support for a specified term and revenue is recognized pro-rata over the term of the engagement.

Shipping and handling costs: Shipping and handling costs collected from our customers in connection with our sales are recorded as revenue. We record shipping and handling costs as a component of cost of sales at the time the product is shipped.

Warranty: Our warranty offerings are described in "Note 11. Commitments and Contingencies."

Disaggregation of revenue

In accordance with ASC 606-10-50, we disaggregate revenue from contracts with customers by the type of performance obligation and the timing of revenue recognition. We determine that disaggregating revenue in these categories achieves the disclosure objective to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors and to enable users of financial statements to understand the relationship to each reportable segment. As noted in the segment information footnote, we are organized in five business segments: Commercial, Live Events, High School Park and Recreation, Transportation, and International.

The following table presents our disaggregation of revenue by segments:




	Commercial		Live Events		High School Park and Recreation		Transportation		International		Total

See "Note 5. Segment Reporting" for a disaggregation of revenue by geography.

Contract Balances

Contract assets represent revenue recognized in excess of amounts billed and include unbilled receivables. Unbilled receivables, which represent an unconditional right to payment subject only to the passage of time, are reclassified to accounts receivable when they are billed under the contract terms. Contract liabilities represent amounts billed to the clients in excess of revenue recognized to date.

We adjust the contract price for the effects of a significant financing component if we expect, at contract inception, that the period between when we transfer goods and services to a customer will exceed one year from the time the customer pays. See "Note 10. Receivables" for amounts recorded in long-term receivables.

The following table reflects the changes in our contract assets and liabilities:



	July 28, 2018		April 28, 2018		Dollar Change		Percent Change
Contract assets	$	41,283	$	30,968	$	10,315	33.3	%
Contract liabilities - current	50,629		39,379		11,250		28.6
Contract liabilities - noncurrent	8,073		7,475		598		8.0

The increase in our contract assets and contract liabilities from April 28, 2018 to July 28, 2018 was due to the timing of billing schedules and revenue recognition, which can vary significantly depending on the contractual payment terms and the seasonality of the sports markets.

During the three months ended July 28, 2018, we recognized revenue of $23,805 related to our contract liabilities as of April 28, 2018.

Remaining performance obligations

As of July 28, 2018, the aggregate amount of the transaction price allocated to the remaining performance obligations, which we also refer to as backlog, was $223,751. We expect approximately $190,219 of our remaining performance obligations to be recognized over the next 12 months with the remainder recognized thereafter. Remaining performance obligations related to product and service agreements are $176,819 and $46,932, respectively. Although remaining performance obligations reflects business that is considered to be legally binding, cancellations, deferrals or scope adjustments may occur. Any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals are reflected in the balance as appropriate.

Segment Reporting [Abstract]

Segment Disclosure

Note 5. Segment Reporting

We have organized our business into five segments which meet the definition of reportable segments under ASC 280-10, Segment Reporting: Commercial, Live Events, High School Park and Recreation, Transportation, and International. These segments are based on the customer type or geography and are the same as our business units.

Our Commercial business unit primarily consists of sales of our integrated video display systems, digital billboards, Galaxy^® and Fuelight^™ product lines, and dynamic messaging systems to resellers (primarily sign companies), Out-of-Home ("OOH") companies, national retailers, quick-serve restaurants, casinos, commercial building owners, and petroleum retailers. Our Live Events business unit primarily consists of sales of integrated scoring and video display systems to college and professional sports facilities and convention centers and sales of our mobile display technology to video rental organizations and other live events type venues. Our High School Park and Recreation business unit primarily consists of sales of scoring systems, Galaxy^® displays and video display systems to primary and secondary education facilities and resellers (primarily sign companies). Our Transportation business unit primarily consists of sales of intelligent transportation systems dynamic messaging signs for road management, mass transit, and aviation applications and other electronic signage for advertising and way-finding needs, which includes our Vanguard^® and Galaxy^® product lines and other intelligent transportation systems dynamic message signs, to governmental transportation departments, transportation industry contractors, airlines and other transportation related customers. Our International business unit consists of sales of all product lines outside the United States and Canada. In our International business unit, we focus on product lines related to integrated scoring and video display systems for sports and commercial applications, OOH advertising products, architectural lighting, and transportation related products.

We evaluate segment performance based on operating results through contribution margin, which is comprised of gross profit less selling expense. Gross profit is net sales less cost of sales. Cost of sales consists primarily of inventory and components, consumables, salaries, other employee-related costs, facilities-related costs for manufacturing locations, machinery and equipment maintenance and depreciation, site sub-contractors, warranty costs, enterprise resource and service management systems, inventory obsolescence and write-downs, inventory procurement and handling costs, and other manufacturing, installation, and service delivery expenses. Selling expenses consist primarily of salaries, other employee-related costs, travel and entertainment expenses, facilities-related costs for sales and service offices, bad debt expenses, third-party commissions and expenditures for marketing efforts, including the costs of collateral materials, conventions and trade shows, product demonstrations, customer relationship management systems, and supplies. Contribution margin excludes general and administration expense, product design and development expense, non-operating income and expense and income tax expense. Some expenses or services are not directly allocable to a sale or segment or the resources and related expenses are shared across business segment areas. These expenses are allocated using estimates and allocation methodologies based on some financial measures and professional judgment. Shared or unabsorbed manufacturing costs are allocated to the business unit benefiting most from that manufacturing location's production capabilities. Shared or unabsorbed costs of domestic field sales and services infrastructure, including most field administrative staff, are allocated to the Commercial, Live Events, High School Park and Recreation, and Transportation business units based on cost of sales. Shared manufacturing, buildings and utilities, and procurement costs are allocated based on payroll dollars, square footage and various other financial measures. Assets are not allocated to the segments. Depreciation and amortization are allocated to each segment based on various financial measures; however, some depreciation and amortization are corporate in nature and remain unallocated. Our segments follow the same accounting policies as those described in Note 1 of our Annual Report on Form 10-K for the fiscal year ended April 28, 2018.

We do not maintain information on sales by products; therefore, disclosure of such information is not practical.

The following table sets forth certain financial information for each of our five reporting segments for the periods indicated:

We have numerous customers worldwide for sales of our products and services, and no customers accounted for 10% or more of net sales; therefore, we are not economically dependent on a limited number of customers for the sale of our products and services except with respect to our dependence on two major digital billboard customers in our Commercial business unit.

We have numerous raw material and component suppliers, and no supplier accounts for 10% or more of our cost of sales; however, we have a number of single-source suppliers that could limit our supply or cause delays in obtaining raw material and components needed in manufacturing.

Marketable Securities [Abstract]

Marketable Securities

Note 6. Marketable Securities

We have a cash management program which provides for the investment of cash balances not used in current operations. We classify our investments in marketable securities as available-for-sale in accordance with the provisions of ASC 320, Investments – Debt and Equity Securities. Marketable securities classified as available-for-sale are reported at fair value with unrealized gains or losses, net of tax, reported in accumulated other comprehensive loss on the condensed consolidated balance sheets. As it relates to fixed income marketable securities, it is not likely we will be required to sell any of these investments before recovery of the entire amortized cost basis. In addition, as of July 28, 2018, we anticipate we will recover the entire amortized cost basis of such fixed income securities, and we have determined no other-than-temporary impairments associated with credit losses were required to be recognized. The cost of securities sold is based on the specific identification method. Where quoted market prices are not available, we use the market price of similar types of securities traded in the market to estimate fair value.

As of July 28, 2018 and April 28, 2018, our available-for-sale securities consisted of the following:



	Amortized Cost		Unrealized Losses			Fair Value
Balance as of July 28, 2018
Certificates of deposit	$	6,189	$	—		$	6,189
U.S. Government securities	1,994		(8		)	1,986

Municipal bonds	4,936		(24		)	4,912
	$	34,676	$	(154	)	$	34,522

Realized gains or losses on investments are recorded in our condensed consolidated statements of operations as "Other (expense) income, net." Upon the sale of a security classified as available-for-sale, the security’s specific unrealized gain (loss) is reclassified out of accumulated other comprehensive loss into earnings based on the specific identification method. In the three months ended July 28, 2018 and July 29, 2017, the reclassifications from accumulated other comprehensive loss to net earnings were immaterial.

All available-for-sale securities are classified as current assets, as they are readily available to support our current operating needs. The contractual maturities of available-for-sale debt securities as of July 28, 2018 were as follows:



	Less than 12 months		1-5 Years		Total
Certificates of deposit	$	2,725	$	3,464	$	6,189

The results of its operations have been included in our condensed consolidated financial statements since the date of acquisition. We have not made pro forma disclosures because the results of its operations are not material to our condensed consolidated financial statements. AJT is a developer of real-time live to air graphics rendering and video server systems for the broadcast TV industry. This acquisition will allow our organization to grow and strengthen our solution offerings to the market. This acquisition was primarily funded with cash on hand.

We perform an analysis of goodwill on an annual basis, and it is tested for impairment more frequently if events or changes in circumstances indicate that an asset might be impaired. We perform our annual analysis during our third quarter of each fiscal year, based on the goodwill amount as of the first business day of our third fiscal quarter. The result of the analysis indicated no goodwill impairment existed for our third quarter in fiscal 2018, which began on October 29, 2017.

In conducting our impairment testing, we compare the fair value of each of our business units to the related carrying value of the allocated assets. We utilize the income approach based on discounted projected cash flows to estimate the fair value of each unit. The projected cash flows use many estimates including market conditions, expected market demand and our ability to grow or maintain market share, gross profit, and expected expenditures for capital and operating expenses. Assets shared or not directly attributed to a reportable segment's activities are allocated to the reportable segment based on sales and other measures.

Receivables	Note 10. Receivables Accounts receivable are reported net of an allowance for doubtful accounts of $2,177 and $2,151 at July 28, 2018 and April 28, 2018, respectively. Included in accounts receivable as of July 28, 2018 and April 28, 2018 was $1,190 and $964, respectively, of retainage on construction-type contracts, all of which is expected to be collected within one year. In connection with certain sales transactions, we have entered into sales contracts with installment payments exceeding 12 months and sales-type leases. The present value of these contracts and leases are recorded as a receivable as the revenue is recognized in accordance with GAAP, and profit is recognized to the extent the present value is in excess of cost. We generally retain a security interest in the equipment or in the cash flow generated by the equipment until the contract is paid. The present value of long-term contracts and lease receivables, including accrued interest and current maturities, was $2,987 and $3,393 as of July 28, 2018 and April 28, 2018, respectively. Contract and lease receivables bearing annual interest rates of 4.8 to 9.0 percent are due in varying annual installments through 2024. The face amount of long-term receivables was $3,267 as of July 28, 2018 and $3,733 as of April 28, 2018.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 11. Commitments and Contingencies

Litigation: We are a party to legal proceedings and claims which arise during the ordinary course of business. We review our legal proceedings and claims, regulatory reviews and inspections, and other legal matters on an ongoing basis and follow appropriate accounting guidance when making accrual and disclosure decisions. We establish accruals for those contingencies when the incurrence of a loss is probable and can be reasonably estimated, and we disclose the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our condensed financial statements to not be misleading. We do not record an accrual when the likelihood of loss being incurred is probable, but the amount cannot be reasonably estimated, or when the loss is believed to be only reasonably possible or remote, although disclosures will be made for material matters as required by ASC 450-20, Contingencies - Loss Contingencies. Our assessment of whether a loss is reasonably possible or probable is based on our assessment and consultation with legal counsel regarding the ultimate outcome of the matter following all appeals.

As of July 28, 2018 and April 28, 2018, we recorded a liability and related other receivable of $1,612 and $1,904 for a net claim from a customer against work performed by one of our subcontractors during installation which damaged our customer's property. The amount recorded is for probable and reasonably estimated cost to remediate the damage. Our subcontractor has full insurance for such matters, we have claims to a performance bond as additional collateral, and we carry insurance to cover such matters. In the opinion of management, the ultimate liability of this claim is not expected to have a material effect on our financial position, liquidity or capital resources.

As of July 28, 2018 and April 28, 2018, a customer was withholding $2,224 of payment claiming we did not perform to the customer's specifications. We believe we have performed to the agreed-upon written specifications, have strong contractual documentation to support our position, and a customer with wherewithal to pay. We believe that we will ultimately prevail in collections. Although our assessment of the loss is remote, a number of factors could change the outcome.

We did not believe there was a reasonable probability that any material loss for other various claims or legal actions, including reviews, inspections or other legal proceedings, if any, would be incurred. Accordingly, no material accrual or disclosure of a potential range of loss has been made related to these matters. We do not expect the ultimate liability of these unresolved legal proceedings to have a material effect on our financial position, liquidity or capital resources.

Warranties: We offer a standard parts coverage warranty for periods varying from one to five years for most of our products. We also offer additional types of warranties to include on-site labor, routine maintenance and event support. In addition, the terms of warranties on some installations can vary from one to 10 years. The specific terms and conditions of these warranties vary primarily depending on the type of product sold. We estimate the costs which may be incurred under the contractual warranty obligations (assurance type warranty) and record a liability in the amount of such estimated costs at the time the revenue is recognized. Factors affecting our estimate of the cost of our warranty obligations include historical experience and expectations of future conditions. We continually assess the adequacy of our recorded warranty accruals and, to the extent we experience any changes in warranty claim activity or costs associated with servicing those claims, our accrued warranty obligation is adjusted accordingly. For service-type warranty contracts, we allocate revenue to this performance obligation and recognize the revenue over time and costs as incurred.

We disclosed a warranty issue in Note 18 of our Annual Report on Form 10-K for the fiscal year ended April 28, 2018 regarding a mechanical device failure within a module for displays. During the three months ended July 28, 2018 and July 29, 2017, we recognized warranty expense for probable and reasonably estimated costs to remediate this issue of $596 and $783, respectively. As of July 28, 2018, we had $1,314 remaining in accrued warranty obligations for the estimate of probable future claims related to this issue. Although many of our contractual warranty arrangements are nearing expiration for products with this issue, we may incur additional discretionary costs to maintain customer relationships or for higher than expected failure rates. Accordingly, it is possible that the ultimate cost to resolve this matter may increase and be materially different from the amount of the current estimate and accrual.

Changes in our warranty obligation for the three months ended July 28, 2018 and July 29, 2017 consisted of the following:



	July 28, 2018			July 29, 2017
Beginning accrued warranty obligations	$	29,953		$	27,899
Warranties issued during the period	2,450			4,128
Settlements made during the period	(3,969		)	(3,493		)
Changes in accrued warranty obligations for pre-existing warranties during the period, including expirations	811			1,219
Ending accrued warranty obligations	$	29,245		$	29,753

Performance guarantees: We have entered into standby letters of credit and surety bonds with financial institutions relating to the guarantee of our future performance on contracts, primarily construction type contracts. As of July 28, 2018, we had outstanding letters of credit and surety bonds in the amount of $12,703 and $14,835, respectively. Performance guarantees are issued to certain customers to guarantee the operation and installation of the equipment and our ability to complete a contract. These performance guarantees have various terms, but are generally one year.

Leases: We lease vehicles, office space and equipment for various global sales and service locations, including manufacturing space in the United States and China. Some of these leases, including the lease for manufacturing facilities in Sioux Falls, South Dakota, include provisions for extensions or purchase. The lease for the facilities in Sioux Falls, South Dakota, can be extended for an additional five years past its current term, which ends March 31, 2022, and it contains an option to purchase the property subject to the lease from March 31, 2017 to March 31, 2022 for $9,000, which approximates fair value. If the lease is extended, the purchase option increases to $9,090 for the year ending March 31, 2023 and $9,180 for the year ending March 31, 2024. Rental expense for operating leases was $858 and $853 for the three months ended July 28, 2018 and July 29, 2017, respectively.

Future minimum payments under noncancelable operating leases, excluding executory costs such as management and maintenance fees, with initial or remaining terms of one year or more consisted of the following at July 28, 2018:



Fiscal years ending	Amount

Purchase commitments: From time to time, we commit to purchase inventory, advertising, cloud-based information systems, information technology maintenance and support services, and various other products and services over periods that extend beyond one year. As of July 28, 2018, we were obligated under the following conditional and unconditional purchase commitments, which included $275 in conditional purchase commitments:

Income Taxes	Jul. 28, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Note 12. Income Taxes Our effective tax rate varies from the federal statutory rate primarily due to state and local taxes, research and development tax credit, and the base erosion anti-abuse tax. We recorded an effective tax rate benefit of 13.1 percent in the first quarter of 2019 as compared to an effective tax rate expense of 29.7 percent for the first quarter of fiscal 2018. The decrease in the effective tax rate is primarily due to projected tax credits in excess of our projected tax liability in conjunction with the decrease in the federal statutory tax rate pursuant to the U.S. Tax Cuts and Jobs Act (the "Tax Act"). We are subject to U.S. federal income tax as well as income taxes of multiple state and foreign jurisdictions. Due to various factors and operating in multiple state and foreign jurisdictions, our effective tax is subject to fluctuation. As a result of the expiration of statutes of limitations, our fiscal years 2015, 2016, 2017, and 2018 are the remaining years open under statutes of limitations for federal and state income tax examinations. Certain subsidiaries are also subject to income tax in several foreign jurisdictions which have open tax years varying by jurisdiction beginning in fiscal 2008. As of July 28, 2018, we had $3,336 of unrecognized tax benefits which would reduce our effective tax rate if recognized. Pursuant to Tax Act, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Act (SAB 118), which allows us to record provisional amounts during a measurement period not to extend beyond one year from the enactment date. The accounting for the deemed repatriation tax is provisional and incomplete due to continued guidance from the U.S. tax authority and our ongoing analysis of final year-end data and tax positions. This provisional estimate was included in our condensed consolidated financial statements as of July 28, 2018 and April 28, 2018. We did not make any measurement period adjustments during the first quarter of 2019. We expect to complete the analysis within the measurement period in accordance with SAB 118. Also, we have determined that we will recognize the Global Intangible Low Taxed Income (GILTI) as a period cost if, and when, incurred. As of July 28, 2018, undistributed earnings of our foreign subsidiaries were considered to have been reinvested indefinitely.

Fair Value Disclosures [Abstract]

Fair Value Measurement

Note 13. Fair Value Measurement

ASC 820, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. It also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy within ASC 820 distinguishes between the following three levels of inputs which may be utilized when measuring fair value.

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included within Level 1 for the assets or liabilities, either directly or indirectly (for example, quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets or liabilities in markets not considered to be active, inputs other than quoted prices that are observable for the asset or liability, or market-corroborated input).

Level 3 - Unobservable inputs supported by little or no market activity based on our own assumptions used to measure assets and liabilities.

The fair values for fixed-rate long-term receivables are estimated using a discounted cash flow analysis based on interest rates currently being offered for contracts with similar terms to customers with similar credit quality. The carrying amounts reported on our condensed consolidated balance sheets for long-term receivables approximate fair value and have been categorized as a Level 2 fair value measurement. Fair values for fixed-rate long-term marketing obligations are estimated using a discounted cash flow calculation applying interest rates currently being offered for debt with similar terms and underlying collateral. The total carrying value of long-term marketing obligations as reported on our condensed consolidated balance sheets within other long-term obligations approximates fair value and has been categorized as a Level 2 fair value measurement.

The following table sets forth by Level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis at July 28, 2018 and April 28, 2018 according to the valuation techniques we used to determine their fair values. There have been no transfers of assets or liabilities among the fair value hierarchies presented.

The following methods and assumptions were used to estimate the fair value of each class of financial instrument. There have been no changes in the valuation techniques used by us to value our financial instruments.

Cash and cash equivalents: Consists of cash on hand in bank deposits and highly liquid investments, primarily money market accounts. The fair value was measured using quoted market prices in active markets. The carrying amount approximates fair value.

Restricted cash: Consists of cash and cash equivalents held in bank deposit accounts to secure issuances of foreign bank guarantees. The fair value of restricted cash was measured using quoted market prices in active markets. The carrying amount approximates fair value.

Certificates of deposit: Consists of time deposit accounts with original maturities of less than three years and various yields. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments from a third-party financial institution. The carrying amount approximates fair value.

U.S. Government securities: Consists of U.S. Government treasury bills, notes, and bonds with original maturities of less than three years and various yields. The fair value of these securities was measured using quoted market prices in active markets.

U.S. Government sponsored entities: Consists of Fannie Mae and Federal Home Loan Bank investment grade debt securities trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments. The contractual maturities of these investments vary from one month to three years.

Municipal bonds: Consists of investment grade municipal bonds trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The contractual maturities of these investments vary from two to three years. The fair value of these bonds was measured based on valuations observed in less active markets than Level 1 investments.

Derivatives – currency forward contracts: Consists of currency forward contracts trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on a valuation from a third-party bank. See "Note 14. Derivative Financial Instruments" for more information regarding our derivatives.

Contingent liabilities: Consists of the fair value of a liability measured on an expected future payment relating to a business acquisition if future financial performance measures are achieved. The contingent liabilities were calculated by estimating the discounted present value of expected future payments for estimated performance measure attainment. To estimate future performance measure attainment, we utilized significant unobservable inputs as of July 28, 2018 and April 28, 2018. The unobservable inputs included management expectations and forecasts for business sales and profits performance and an estimated discount rate based on current borrowing interest rates. To the extent that these assumptions changed, or actual results differed from these estimates, the fair value of the contingent consideration liabilities could change from $2,309 to $0 or increase in proportion to increased business performance from this estimate. The contingent liabilities are presented in the "Current portion of other long-term obligations" and "Other long-term obligations" line items in our condensed consolidated balance sheets.

Non-recurring measurements: The fair value measurement standard also applies to certain non-financial assets and liabilities measured at fair value on a nonrecurring basis. Certain long-lived assets such as goodwill, intangible assets and property and equipment are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.

Other measurements using fair value: Some of our financial instruments, such as accounts receivable, long-term receivables, prepaid expense and other assets, contract assets and liabilities, accounts payable, warranty obligations, and other long-term obligations, are reflected in the condensed consolidated balance sheets at carrying value, which approximates fair value due to their short-term nature.

Derivative Financial Instruments

Note 14. Derivative Financial Instruments

We utilize derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates on those transactions denominated in currencies other than our functional currency, which is the U.S. dollar. We enter into currency forward contracts to manage these economic risks. We account for all derivatives on the condensed consolidated balance sheets within accounts receivable or accounts payable measured at fair value, and changes in fair values are recognized in earnings unless specific hedge accounting criteria are met for cash flow or net investment hedges. As of July 28, 2018 and April 28, 2018, we had not designated any of our derivative instruments as accounting hedges, and thus we recorded the changes in fair value in "Other (expense) income, net" in the condensed consolidated statements of operations.

The foreign currency exchange contracts in aggregated notional amounts in place to exchange U.S. dollars at July 28, 2018 and April 28, 2018 were as follows:

Basis of Presentation (Policies)	Jul. 28, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Standards Adopted In October 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-16, Income Taxes (Topic 740) Intra-Entity Transfers of Assets Other than Inventory, which is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party, which is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. This update eliminates the exception by requiring entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. We have adopted ASU 2016-16 during the first quarter of fiscal 2019. The adoption of ASU 2016-16 did not have an impact on our condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Subsequently, the FASB also issued ASUs 2016-08, 2016-10, 2016-12, and 2016-20 to give further guidance to revenue recognition matters. ASU 2014-09 and related guidance supersedes revenue recognition requirements under FASB Accounting Standards Codification ("ASC") Topic 605 and related industry specific revenue recognition guidance. This new standard defines a comprehensive revenue recognition model, requiring a company to recognize revenue from the transfer of goods or services to customers in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. It defines a five-step process to achieve this core principle and allows companies to use more judgment and make more estimates than under current guidance and requires additional disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the customer contracts. It provides guidance on transition requirements. We have adopted ASU 2014-09 and its related guidance under the modified retrospective method during the first quarter of fiscal 2019 by applying the guidance to all open contracts at the adoption date. We have completed our evaluation of our revenue arrangements under the new standard and have assessed that the adoption did not materially change the timing or amount of revenue recognized, primarily based upon our assessment of "point in time" and "over time" revenue recognition. No adjustment to beginning retained earnings was recorded, and we have made additional disclosures related to revenue from contracts with customers as required by the new standard upon adoption. See "Note 4. Revenue Recognition" for more information. New Accounting Standards Not Yet Adopted In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate under the U.S. Tax Cuts and Jobs Act (the "Tax Act"). ASU 2018-02 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted that can be made on a prospective or retrospective basis. We are currently evaluating the effect that adopting ASU 2018-02 will have on our condensed consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. A goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for interim and annual periods beginning after December 15, 2019 and will require adoption on a prospective basis. We are currently evaluating the effect that adopting ASU 2017-04 will have on our condensed consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides guidance regarding the measurement and recognition of credit impairment for certain financial assets. ASU 2016-13 is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted, and will require adoption on a modified retrospective basis. We are currently evaluating the effect that adopting ASU 2016-13 will have on our condensed consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (that is, lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. ASU 2016-02 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842 (Leases), and ASU 2018-11, Leases (Topic 842), Targeted Improvements, which provide (i) narrow amendments to clarify how to apply certain aspects of the new lease standard, (ii) entities with an additional transition method to adopt the new standard, and (ii) lessors with a practical expedient for separating components of a contract. All ASUs are effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and will require adoption on a modified retrospective basis. We are currently evaluating the effect that adopting these ASUs will have on our condensed consolidated financial statements and related disclosures.
