[1] Derived from audited financial statements.

[2] Due to the adoption of new authoritative accounting guidance at the beginning of our fiscal year (see Note 1), we were required to perform a goodwill Step 2 impairment test for our Services reporting unit. As a result, we recognized an impairment loss of $19 million which reduced the carrying value of goodwill reported in the Services reporting segment to zero. The valuation technique used by the Company to estimate the fair value of the Services reporting unit goodwill, relies on Level 3 inputs, including estimated fair value using future cash flows or profit streams. This impairment was recorded to beginning Accumulated deficit as a cumulative-effect adjustment upon adoption.

[3] Goodwill acquired through business combinations is related to the acquisition of Clearwell, see Note 3 for further information.

[4] Reflects adjustments made to goodwill as a result of foreign currency exchange rate fluctuations.
