Critical Accounting Judgments and Key Sources of Estimation Uncertainty The preparation of financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, and revenue and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and further periods if the review affects both current and future periods. Critical areas of estimation and judgements in applying accounting policies include the following: Intangible Assets and Business Combinations Assets acquired and liabilities assumed as part of a business combination are recognized at their acquisition date fair values. In determining these fair values, we utilize various forms of the income, cost, and market approaches depending on the asset or liability being valued. We use a discounted cash flow model to measure the trade names, customer relationship, and technology assets. The estimation of fair value requires significant judgment related to future net cash flows based on assumptions related to revenue and EBITDA growth rates, discount rates, and attrition factors. Inputs are generally determined by taking into account competitive trends, market comparisons, independent appraisals, and historical data, among other factors, and are supplemented by current and anticipated market conditions. Impairment Testing We evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change indicating the carrying value may not be recoverable. When testing goodwill for impairment, we may first assess qualitative factors to determine if it is more likely than not the carrying value of a reporting unit exceeds its estimated fair value. During a qualitative analysis, we consider the impact of changes, if any, to the following factors: macroeconomic, industry and market factors; cost factors; changes in overall financial performance; and any other relevant events and uncertainties impacting a reporting unit. If our qualitative assessment indicates a goodwill impairment is more likely than not, we perform additional quantitative analyses. We may also elect to skip the qualitative testing and proceed directly to the quantitative testing. For reporting units where a quantitative analysis is performed, we perform a test measuring the fair values of the reporting units and comparing them to their aggregate carrying values, including goodwill. If the fair value is less than the carrying value of the reporting unit, an impairment is recognized for the difference, up to the carrying amount of goodwill. We estimate the fair values of our reporting units using a discounted cash flow method or a weighted combination of discounted cash flows and a market-based method. The discounted cash flow method includes assumptions about a wide variety of internal and external factors. Significant assumptions used in the discounted cash flow method include financial projections of free cash flow, including revenue trends, medical costs trends, operating productivity, income taxes and capital levels; long-term growth rates for determining terminal value beyond the discretely forecasted periods; and discount rates. Financial projections and long-term growth rates used for our reporting units will be consistent with, and use inputs from, our internal long-term business plan and strategies. Discount rates will be determined for each reporting unit and include consideration of the implied risk inherent in their forecasts. Our most significant estimate in the discount rate determinations involves our adjustments to the peer company weighted average costs of capital reflecting reporting unit-specific factors. We do not make any adjustments to decrease a discount rate below the calculated peer company weighted average cost of capital for any reporting unit. Company-specific adjustments to discount rates are subjective and thus are difficult to measure with certainty. The passage of time and the availability of additional information regarding areas of uncertainty with respect to the reporting units’ operations could cause these assumptions to change in the future. Additionally, as part of our quantitative impairment testing, we perform various sensitivity analyses on certain key assumptions, such as discount rates, cash flow projections, and peer company multiples to analyze the potential for a material impact. The market-based method requires determination of an appropriate peer group whose securities are traded on an active market. The peer group is used to derive market multiples to estimate fair value.

An estimate is made of the anticipated future revenue over the life of the instrument, based on the sale of assays, which is typically ten years. If the payback period of the initial investment in the asset is less than the ten-year life of the asset, we conclude that the assets have been properly recorded, and no write-down is necessary.

4. Critical Accounting Judgments and Key Sources of Estimation Uncertainty

The preparation of financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, and revenue and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and further periods if the review affects both current and future periods.

Critical areas of estimation and judgements in applying accounting policies include the following:

Intangible Assets and Business Combinations

Assets acquired and liabilities assumed as part of a business combination are recognized at their acquisition date fair values. In determining these fair values, we utilize various forms of the income, cost, and market approaches depending on the asset or liability being valued.

We use a discounted cash flow model to measure the trade names, customer relationship, and technology assets. The estimation of fair value requires significant judgment related to future net cash flows based on assumptions related to revenue and EBITDA growth rates, discount rates, and attrition factors. Inputs are generally determined by taking into account competitive trends, market comparisons, independent appraisals, and historical data, among other factors, and are supplemented by current and anticipated market conditions.

Impairment Testing

We evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change indicating the carrying value may not be recoverable. When testing goodwill for impairment, we may first assess qualitative factors to determine if it is more likely than not the carrying value of a reporting unit exceeds its estimated fair value. During a qualitative analysis, we consider the impact of changes, if any, to the following factors: macroeconomic, industry and market factors; cost factors; changes in overall financial performance; and any other relevant events and uncertainties impacting a reporting unit. If our qualitative assessment indicates a goodwill impairment is more likely than not, we perform additional quantitative analyses.

For reporting units where a quantitative analysis is performed, we perform a test measuring the fair values of the reporting units and comparing them to their aggregate carrying values, including goodwill. If the fair value is less than the carrying value of the reporting unit, an impairment is recognized for the difference, up to the carrying amount of goodwill.

rates. Financial projections and long-term growth rates used for our reporting units will be consistent with, and use inputs from, our internal long-term business plan and strategies.
