Management believes that it is useful in measuring Thoratec's operations to exclude amortization of intangibles. These costs are primarily fixed at the time of an acquisition and, unlike other fixed costs that result from ordinary operations, are the result of infrequent and irregular events.
Because of varying valuation methodologies, subjective assumptions and the variety of award types that companies can use, Thoratec management believes that providing non-GAAP financial measures that exclude share-based compensation allows investors to compare Thoratec's recurring core business operating results to those of other companies and over multiple periods. The exclusion also enhances investors' ability to review Thoratec's business from the same perspective as Thoratec managemen
