Avocent Files First Quarter 10-Q

Avocent Corporation (NASDAQ: AVCT), today announced the filing of its first quarter 2009 Form 10-Q with the Securities and Exchange Commission. The Company previously issued preliminary results on April 23, 2009 for the first quarter pending a review of goodwill as required by FASB Statement 142 “Goodwill and Other Intangible Assets.” The Company has now revised its estimate for goodwill impairment to $80 million and expects to finalize its assessment of goodwill impairment during the second quarter of 2009. The goodwill impairment charge is subject to change as the Company completes its evaluation, and any resulting change could vary materially from the estimate recorded during the first quarter of 2009. The Company will record any difference during the second quarter of 2009.

The goodwill impairment charge is an accounting adjustment under generally accepted accounting principles (“GAAP”) that does not affect current operations, cash flows, liquidity, or future operations. The non-GAAP results previously announced by the Company are not affected by the revised estimate.
