Revenue recognition

The Company recognizes revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) shipment has occurred or delivery has occurred if the terms specify destination; (3) the sales price is fixed or determinable; and (4) collectability is reasonably assured. When there are additional performance requirements, revenue is recognized when all such requirements have been satisfied. Under revenue arrangements with multiple deliverables, the Company recognizes each separable deliverable as it is earned.

The Company derives its revenue from three primary sources: (1) royalties and license fees from licensing its proprietary drug delivery and surface modification technologies and in vitro diagnostic formats to customers; (2) the sale of reagent chemicals to licensees and the sale of stabilization products, antigens, substrates and surface coatings to the diagnostic and biomedical research markets; and (3) research and development fees generated on customer projects.

Royalties and license fees

Royalties and license fees. The Company licenses technology to third parties and collects royalties. Royalty revenue is generated when a customer sells products incorporating the Company’s licensed technologies. Royalty revenue is recognized as licensees report it to the Company, and payment is typically submitted concurrently with the report. For stand-alone license agreements, up-front license fees are recognized over the term of the related licensing agreement. Minimum royalty fees are recognized in the period earned.

Revenue related to a performance milestone is recognized upon the achievement of the milestone, as defined in the respective agreements and provided the following conditions have been met:

•

The milestone payment is non-refundable;

•

The milestone involved a significant degree of risk, and was not reasonably assured at the inception of the arrangement;

•

Accomplishment of the milestone involved substantial effort;

•

The amount of the milestone payment is commensurate with the related effort and risk; and

•

A reasonable amount of time passed between the initial license payment and the first and subsequent milestone payments.

If these conditions have not been met, the milestone payment is deferred and recognized over the term of the agreement.

Product sales

Product sales. Product sales to third parties are recognized at the time of shipment, provided that an order has been received, the price is fixed or determinable, collectability of the resulting receivable is reasonably assured and returns can be reasonably estimated. The Company’s sales terms provide no right of return outside of the standard warranty policy. Payment terms are generally set at 30-45 days.

Research and development

Research and development. The Company performs third party research and development activities, which are typically provided on a time and materials basis. Generally, revenue for research and development is recorded as performance progresses under the applicable contract.

New Accounting Pronouncements

New Accounting Pronouncements

Recently Adopted

In June 2011, and subsequently amended in December 2011, the Financial Accounting Standards Board (“FASB”) issued final guidance on the presentation of comprehensive income. Under the newly issued guidance, the total of comprehensive income, the components of net income, and the components of other comprehensive income may only be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company adopted this guidance in the first quarter of fiscal 2013, with comprehensive income shown as a separate condensed consolidated statement immediately following the condensed consolidated statements of income. Since the new guidance only relates to presentation, its adoption did not impact the Company’s financial position, results of operations, or cash flows.

No other new accounting pronouncement issued or effective has had, or is expected to have, a material impact on the Company’s consolidated financial statements.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
