We allocated the purchase price of the acquisition to identifiable intangible assets based on their estimated fair values. Intangible assets were valued using the relief from royalty and discounted cash flow methodologies which are considered Level 3 fair value measurements. The relief from royalty method estimates our theoretical royalty savings from ownership of the intangible assets. Key assumptions used in this model include discount rates, royalty rates, growth rates and sales projections. Discount rates, royalty rates, growth rates and sales projections are the assumptions most sensitive and susceptible to change as they require significant management judgment. The key assumptions used in the discounted cash flow valuation model include discount rates, growth rates and cash flow projections. Discount rates, growth rates and cash flow projections are the most sensitive and susceptible to change as they require significant management judgment.
