Tyco International

(TYC)

said Thursday that the

Securities and Exchange Commission

has ended its informal investigation of the company's accounting practices.

The diversified manufacturing company said that it had received a letter from the SEC notifying it that the investigation was over and that "at this time no enforcement action has been recommended to the Commission."

Pembroke, Bermuda-based Tyco

announced last month that it has amended its earnings for fiscal 1999 and the first quarter of fiscal 2000 after a review by SEC accountants. The company said it would raise its earnings per share by 2 cents for fiscal 1999 and decrease its earnings per share for the first quarter of fiscal 2000 by the same amount.

Thursday's announcement appears to mark the formal end of the SEC investigation and the culmination of the company's latest difficulties that began in October when an investor newsletter questioned Tyco's accounting practices as it went on a merger binge. Later, in December, at Tyco's request the SEC launched a "nonpublic, informal inquiry" into the company's books.

Over the last six years, Tyco, an industrial conglomerate that produces electrical and electronic components, undersea cables for telecommunications systems, disposable medical supplies and fire detection systems, has acquired more than 120 companies valued at $30 billion.

Tyco rose 13/16 to 52 in after-hours trading, according to

Instinet

. During the regular session, it rose 2 11/16, to close at 51 3/16.
