We allocate the purchase price of acquired businesses to the estimated fair values of the assets acquired and liabilities assumed as of the date of the acquisition. The calculations used to determine the fair value of the long-lived assets acquired, primarily intangible assets, can be complex and require significant judgment. We weigh many factors when completing these estimates including, but not limited to, the nature of the acquired company’s business; its competitive position, strengths, and challenges; its historical financial position and performance; estimated customer retention rates; discount rates; and future plans for the combined entity. We may also engage independent valuation specialists, when necessary, to assist in the fair value calculations for significant acquired long-lived assets.
The fair value of acquired technology is generally the primary asset identified and therefore estimated using the multi-period excess earnings method. The multi-period excess earnings method model estimates revenues and cash flows derived from the primary asset and then deducts portions of the cash flow that can be attributed to supporting assets, such as Trade Names and in-process research and development, that contributed to the generation of the cash flows. The resulting cash flow, which is attributable solely to the primary asset acquired, is then discounted at a rate of return commensurate with the risk of the asset to calculate a present value. The Trade Name is generally calculated using the relief from royalty method, which calculates the cost savings associated with owning rather than licensing the technology. Assumed royalty rates are applied to the projected revenues for the remaining useful life of the technology to estimate the royalty savings. In-process research and development assets are valued using the multi-period excess earnings method when the cash flows from the in-process research and development assets are separately identifiable from the primary asset. In circumstances that Customer Relationship assets are identified that are not the primary asset, they are valued using the distributor model income approach, which isolates revenues and cash flow associated with the sales and distribution function of the entity and attributable to customer-related assets, which are then discounted at a rate of return commensurate with the risk of the asset to calculate a present value.
We estimate the fair value of liabilities for contingent consideration by discounting to present value the probability weighted contingent payments expected to be made. For potential payments related to financial performance based milestones, projected revenue and/or EBITDA amounts, volatility and discount rates assumptions are included in the estimated amounts. For potential payments related to product development milestones, the fair value is based on the probability of achievement of such milestones. The excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Goodwill is not amortized, but is subject to impairment testing on at least an annual basis.
We are also required to estimate the useful lives of the acquired intangible assets, which determines the amount of acquisition-related amortization expense we will record in future periods. Each reporting period, we evaluate the remaining useful lives of our amortizable intangibles to determine whether events or circumstances warrant a revision to the remaining period of amortization.
While we use our best estimates and assumptions, our fair value estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any adjustments required after the measurement period are recorded in the consolidated statements of earnings.
The judgments required in determining the estimated fair values and expected useful lives assigned to each class of assets and liabilities acquired can significantly affect net income. For example, different classes of assets will have useful lives that differ. Consequently, to the extent a longer-lived asset is ascribed greater value than a shorter-lived asset, net income in a given period may be higher. Additionally, assigning a lower value to amortizable intangibles would result in a higher amount assigned to goodwill. As goodwill is not amortized, this would benefit net income in a given period, although goodwill is subject to annual impairment analysis.
