3. Significant Accounting Policies

Use of Estimates

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.

Reclassifications

Certain prior-period amounts have been reclassified to conform to current year presentation.

Subsequent Events

The Company has evaluated subsequent events for recognition and disclosure for occurrences and transactions after the date of the condensed financial statements at May 31, 2011.

Revenue Recognition

The Company records revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred, the Company’s price to the customer is fixed and determinable, and collectability is reasonably assured. Delivery is not considered to have occurred until the customer assumes the risks and rewards of ownership. Customers take delivery at the time of shipment for terms designated free on board shipping point. For sales designated free on board destination, customers take delivery when the product is delivered to the customer’s delivery site. Provisions for certain rebates, sales incentives, product returns, and discounts to customers are recorded in the same period the related revenue is recorded. The Company also maintains one-time or on-going marketing and trade-promotion programs with certain customers that require the Company to estimate and accrue the expected costs of such programs. These arrangements include cooperative marketing programs, merchandising of the Company’s products, and introductory marketing funds for new products and other trade-promotion activities conducted by the customer. Costs associated with these programs are reflected within the Company’s Consolidated Statements of Income in accordance with the Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition (“ASC 605”), which in most instances requires such costs be recorded as a reduction of revenue.

The Company provides for limited product return rights to certain distributors and customers, primarily for slow moving or damaged items subject to certain defined criteria. The Company monitors product returns and, at the time revenue is recognized, records a provision for the estimated amount of future returns based primarily on historical experience and specific notification of pending returns. 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 impact on the Company’s operating results in future periods.

Revenue is earned on services and the sale of products. Revenue is recognized for the sale of products when the above criteria are met and for services rendered in the period of performance.

Revenue Recognition for Arrangements with Multiple Deliverables

A small portion of the Company’s revenues are derived from (i) the sale and license of its products, (ii) fees associated with training, installation, and technical support services, and (iii) monitoring and control services. Certain agreements, particularly related to lighting controls systems, represent multiple-element arrangements that include tangible products that contain software that is essential to the functionality of the systems and undelivered elements that primarily relate to installation and monitoring and control services. The undelivered elements associated with installations and monitoring and control services are reviewed and analyzed to determine separability in relation to the delivered elements and appropriate pricing treatment based on (a) vendor-specific objective evidence, (b) third-party evidence, or (c) estimates. If deemed separate units of accounting, the revenue and associated cost of sales related to the delivered elements are realized at the time of delivery, while those related to the undelivered elements are recognized appropriately based on the period of performance. If the separation criterion for the undelivered elements is not met due to the undelivered elements being essential to the functionality of the lighting controls systems, all revenue and cost of sales attributable to the contract are deferred at the time of sale and are both generally recognized on a straight-line basis over the respective contract periods.
