Revenue from Contract with Customer [Abstract]

We recognize revenue when we transfer control of goods and services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for goods and services and is recognized net of allowances for rebates, sales incentives, product returns, and discounts to customers. Sales and use taxes collected on behalf of governmental authorities are excluded from revenues. Payment is generally due and received within 60 days from the point of sale or prior to the transfer of control of certain goods and services. No payment terms extend beyond one year, and we apply the practical expedient within ASC 606 to conclude that no significant financing terms exist within our contracts with customers. Allowances for cash discounts to customers are estimated using the expected value method based on historical experience and are recorded as a reduction to sales. Our standard terms and conditions of sale allow for the return of certain products within four months of the date of shipment. We also provide for limited product return rights to certain distributors and other customers, primarily for slow moving or damaged items subject to certain defined criteria. The limited product return rights generally allow customers to return resalable products purchased within a specified time period and subject to certain limitations, including, at times, when accompanied by a replacement order of equal or greater value. At the time revenue is recognized, we record a refund liability for the expected value of future returns primarily based on historical experience, specific notification of pending returns, or based on contractual terms with the respective customers. Although historical product returns generally have been within expectations, there can be no assurance that future product returns will not exceed historical amounts. A significant increase in product returns could have a material adverse impact on our operating results in future periods.

Total refund liabilities recorded under ASC 606 related to rights of return, cash discounts, and other miscellaneous credits to customers were $38.8 million and $41.2 million as of May 31, 2019 and September 1, 2018, respectively, and are reflected within Other accrued liabilities on the Consolidated Balance Sheets. Additionally, we record right of return assets for products expected to be returned to our distribution centers, which are included within Prepayments and other current assets on the Consolidated Balance Sheets. Such assets totaled $15.3 million and $16.4 million as of May 31, 2019 and September 1, 2018, respectively.

We also maintain one-time or ongoing marketing and trade-promotion programs with certain customers that require us to estimate and accrue the expected costs of such programs. These arrangements include cooperative marketing programs, merchandising of our products, introductory marketing funds for new products, and other trade-promotion activities conducted by the customer. Costs associated with these programs are generally estimated based on the most likely amount expected to be settled based on the context of the individual contract and are reflected within the Consolidated Statements of Comprehensive Income in accordance with ASC 606, which in most instances requires such costs to be recorded as reductions of revenue. The refund liabilities associated with these programs totaled $31.8 million and $43.9 million as of May 31, 2019 and September 1, 2018, respectively, and are reflected within Other accrued liabilities on the Consolidated Balance Sheets.

Costs to obtain and fulfill contracts, such as sales commissions and shipping and handling activities, are short-term in nature and are expensed as incurred.

Nature of Goods and Services

Products

Approximately 95% of revenues for the periods presented were generated from short-term contracts with our customers to deliver tangible goods such as luminaires, lighting controllers, controllers for various building systems, power supplies, prismatic skylights, and drivers. We record revenue from these contracts when the customer obtains control of those goods. For sales designated free on board shipping point, control is transferred at the time of shipment. For sales designated free on board destination, customers take control when a product is delivered to the customer’s delivery site.

Professional Services

We collect fees associated with training, installation, and technical support services, primarily related to the set up of our lighting solutions. We recognize revenue for these one-time services at the time the service is performed. We also sell certain service-type warranties that extend coverages for products beyond their base warranties. We account for service-type warranties as distinct performance obligations and recognize revenue for these contracts ratably over the life of the additional warranty period. Claims related to service-type warranties are expensed as incurred.

Software

Software sales include licenses for software, data usage fees, and software as a service arrangements, which generally extend for one year or less. We recognize revenue for software based on the contractual rights provided to a customer, which typically results in the recognition of revenue ratably over the contractual service period.

Shipping and Handling Activities

We account for all shipping and handling activities as activities to fulfill the promise to transfer products to our customers. As such, we do not consider shipping and handling activities to be separate performance obligations, and we expense these costs as incurred.

Contracts with Multiple Performance Obligations

A small portion (approximately 5% for the periods presented) of our revenue was derived from the combination of any or all of our products, professional services, and software licenses. Significant judgment may be required to determine which performance obligations are distinct and should be accounted for separately. We allocate the expected consideration to be collected to each distinct performance obligation based on its standalone selling price. Standalone selling price is generally determined using a cost plus margin valuation when no observable input is available. The amount of consideration allocated to each performance obligation is recognized as revenue in accordance with the timing for products, professional services, and software as described above.

Contract Balances

Our rights related to collections from customers are unconditional and are reflected within Accounts receivable on the Consolidated Balance Sheets. We do not have any other significant contract assets. Contract liabilities arise when we receive cash or an unconditional right to collect cash prior to the transfer of control of goods or services.

The amount of transaction price from contracts with customers allocated to our contract liabilities as of May 31, 2019 and September 1, 2018 consists of the following (in millions):



	May 31, 2019		September 1, 2018
Current deferred revenues	$	8.5	$	4.8
Non-current deferred revenues	43.7		35.0

Current deferred revenues primarily consist of customer prepayments, software licenses, and to a lesser extent professional service and sales-type warranty fees collected prior to performing the related service. Current deferred revenues are included within Other current liabilities on the Consolidated Balance Sheets. These services are expected to be performed within one year. Non-current deferred revenues primarily consist of long-term service-type warranties, which are typically recognized ratably as revenue between five and ten years from the date of sale, and are included

within Other long-term liabilities on the Consolidated Balance Sheets. Revenue recognized from beginning balances of contract liabilities during the nine months ended May 31, 2019 totaled $3.7 million.

Unsatisfied performance obligations that do not represent contract liabilities consist primarily of orders for physical goods that have not yet been shipped. This backlog of orders at any given time is affected by various factors, including seasonality, cancellations, sales promotions, production cycle times, and the timing of receipt and shipment of orders, which are usually shipped within a few weeks of order receipt. Accordingly, a comparison of backlog orders from period to period is not necessarily meaningful and may not be indicative of future shipments.

Disaggregated Revenues

Our lighting and building management solutions are sold primarily through independent sales agents who cover specific geographic areas and market channels, by internal sales representatives, through consumer retail channels, and directly to large corporate accounts. The following table shows revenue from contracts with customers by sales channel for the three and nine months ended May 31, 2019 (in millions):
