(3)	Revenue Recognition

In the United States, the Company sells its products and services directly to hospitals and clinics. Revenue is recognized in accordance with generally accepted accounting principles as outlined in ASC Topic 605-10-S99, Revenue Recognition, which requires that four basic criteria be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) the price is fixed or determinable; (iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. The Company recognizes revenue as products are shipped and title passes to customers based on FOB shipping point terms. The Company negotiates credit terms on a customer-by-customer basis and products are shipped at an agreed-upon price.

In all international markets, the Company sells its products to international distributors which subsequently resell the products to hospitals and clinics. The Company has agreements with each of its distributors which provide that title and risk of loss pass to the distributor upon shipment of the products to the distributor. The Company warrants that its products are free from manufacturing defects at the time of shipment to the distributor. Revenue is recognized upon shipment of products to distributors following the receipt and acceptance of a distributor’s purchase order and is reported on a gross basis. Allowances are provided for estimated returns and costs at the time of shipment. Sales and use taxes are reported on a net basis, excluding them from revenue.

The Company’s revenues from license agreements and research collaborations are recognized when earned. In accordance with ASC Topic 605, for revenues which contain multiple deliverables, the Company separates the deliverables into separate accounting units if they meet the following criteria: (i) the delivered items have a stand-alone value to the customer; (ii) the fair value of any undelivered items can be reliably determined; and (iii) if the arrangement includes a general right of return, delivery of the undelivered items is probable and substantially controlled by the seller. Deliverables that do not meet these criteria are combined with one or more other deliverables into one accounting unit. Revenue from each accounting unit is recognized based on the applicable accounting literature, primarily ASC Topic 605.

The Company currently has a license agreement with King Pharmaceuticals, Inc. (King), now a subsidiary of Pfizer, Inc., under which the Company licensed the exclusive rights of Thrombi-Pad^TM, Thrombi-Gel^® and Thrombi-Paste^TM products to King in exchange for a license fee. The Company is amortizing the license fees on a straight-line basis over the projected 10 year economic life of the products. The Company determines the economic life of the products under its license agreements by evaluating similar products the Company has launched or other similar products in the medical industry.

Starting in January 2012, the Company began to generate revenue from selling a reprocessing service for ClosureFAST^® radiofrequency catheters. In accordance with ASC Topic 605-45, the Company recognizes this revenue gross with the amount paid to the supplier of the reprocessing service reflected as cost of goods sold.

In addition, the Company has reviewed the provisions of ASC Topic 808, Collaborative Arrangements, and determined that the adoption of this ASC has had no impact on the amounts recorded under these agreements.

In accordance with ASC Topic 605-45-45, the Company includes shipping and handling revenues in net revenue, and shipping and handling costs in cost of goods sold.
