Goodwill and Intangible Assets Disclosure [Abstract]

We have two operating and reportable segments: (1) Software Products and (2) Professional Services. We assess goodwill for impairment at the reporting unit level. Our reporting units are determined based on the components of our operating segments that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by segment management. Our reporting units are the same as our operating segments.

As of December 28, 2019, goodwill and acquired intangible assets in the aggregate attributable to our Software Products segment was $1,826.4 million and attributable to our Professional Services segment was $45.7 million. As of September 30, 2019, goodwill and acquired intangible assets in the aggregate attributable to our Software Products segment was $1,362.4 million and attributable to our Professional Services segment was $45.7 million. Acquired intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable.

We completed our annual goodwill impairment review as of June 29, 2019 based on a qualitative assessment. Our qualitative assessment included company specific (financial performance and long-range plans), industry, and macroeconomic factors, and consideration of the fair value of each reporting unit relative to its carrying value at the last valuation date. Based on our qualitative assessment, we believe it is more likely than not that the fair values of our reporting units exceed their carrying values and no further impairment testing is required.
