After watching their stocks soar to astounding heights in 1999, the technology chief executives with the highest net worth looked on helplessly in 2000 as their fortunes dwindled, in some cases to mere millions. At least seven executives who could call themselves billionaires 12 months ago tumbled to petty millionaire status by the end of the year. Meanwhile, not a single tech chief executive stepped up from the millionaire's club into the billionaire league, according to CNET's chief executive Wealth Meter. Conversely, in 1999, 14 high-tech chief executives added at least $1bn in paper wealth. The billionaire boys' club lost members last year because of a dramatic slide in tech stocks: the tech-heavy Nasdaq composite index lost about 37 percent of its value, and the shares of many individual Net companies plunged by more than 90 percent. 2000 was a rough year for technology chief executives, many of whom watched their net worth plunge by billions of dollars. Winners:

• Larry Ellison, Oracle, +$3.9bn
• Thomas M Siebel, Siebel Systems, +$1.2bn
• B Thomas Golisano, Paychex, +$954m

• Sanjiv Sidhu, I2 Technologies, +$238m
• Patrick H Nettles, Ciena, +$232m

• Michael Dell, Dell Computer, -$10.3bn
• Jeff Bezos, Amazon.com, -$6.9bn
• Bobby Johnson, Foundry Networks, -$3.0bn
• Robert Glaser, Real Networks, -$2.7bn
• David S Wetherell, CMGI, -$2.1bn
• Pehong Chen, Broadvision, -$2.1bn

Even blue chip technology companies from Intel to Microsoft to Cisco Systems were pounded. Microsoft shares, for example, lost some 60 percent in 2000, shaving an astounding $50bn from chairman Bill Gates' net worth. "For technology investors, it was one of the worst years on record, if not the worst," said Charles Reinhard, senior US equity strategist with Lehman Brothers. "To the degree that their wealth is tied to the price of their stock, technology chief executives saw their wealth diminish too." CNET News.com derived the following list based on the number of shares held and options that were exercisable within 60 days of the companies' most recent proxy statements filed with the Securities and Exchange Commission. The values of the individual stocks are based on the closing price 26 December. The figures do not reflect other assets owned by the chief executives, such as real estate or stakes in other companies. The losers: David Wetherell, the chief executive officer of Internet investment company CMGI, ended the year as the biggest money loser. After starting out with CMGI shares valued at $2.1bn, he ended the year with a "mere" $100m, a 95 percent decline. CMGI investors, who have watched the comany's shares plunge from $138.43 to about $6 during the year, have shown little sympathy for Wetherell's personal $2bn loss. At a recent CMGI shareholders meeting, some angry investors called for Wetherell's resignation. The tone was a far cry from last year's annual meeting, when many investors -- giddy with a 870 percent return on their shares -- asked the chief executive for his autograph. Microsoft chief executive Steve Ballmer also took a substantial hit this year, as the value of his share of the software giant fell from $27.9bn to $11.2bn, a loss of $16.7bn, or 60 percent. Microsoft's stock declined a hefty 61 percent last year, culminating in December when the software giant told shareholders that it would miss its earnings estimates for the first time in more than a decade. Microsoft blamed its shortfall on the sectorwide slowdown in PC sales that affected companies from PC makers Dell Computer, Compaq Computer and Apple Computer to chipmakers Intel and Advanced Micro Devices. The company's troubles also cut into the bank accounts of Gates and Microsoft co-founder Paul Allen. Gates, who handed over his chief executive duties to Ballmer in January, has watched his bankroll dwindle to $34bn from $85bn. Allen lost some $40bn as Microsoft shares fell from $116.75 at the beginning of the year to about $44 last week, a 61 percent slide. Michael Dell, chief executive of Dell Computer, also gave some back last year. The 35-year-old watched his net worth dive from $15.6bn to $5.3bn, a loss of $10bn, or 66 percent. Dell was among the PC makers battered by a slowdown in sales of desktop and notebook computers. The company's stock tumbled from $51 to $17.69, a 65 percent decline. Amazon.com chief executive Jeff Bezos, Time magazine's 1999 "Person of the Year", watched his personal wealth shrink by 78 percent, from $8.9bn to $1.9bn. Amazon was battered by a series of problems last year: the company again failed to turn a profit, and many analysts questioned whether its uncertain prospects deserved such a high stock valuation. Its stock tumbled 77 percent to about $17. The winners: Not everyone lost money. Larry Ellison, the Oracle chief executive known for his disdain of Microsoft and a love of yacht racing, logged a hefty $3.8bn increase in wealth last year. Ellison saw his net worth jump 10 percent -- from $37bn at the beginning of 2000 to $40bn. Other winners include Siebel Systems chief executive Thomas Siebel, who gained $1.2bn, and Rambus chief executive Geoff Tate, who made $76m. Last spring, the worth of Ellison's stake in Oracle briefly eclipsed the Microsoft shares held by business rival Gates, who routinely ranks as the richest person in the world. In April, Ellison was worth $53bn, compared with Gates' $51.75bn. See techTrader for technology investment news, plus quotes and research. Have your say instantly, and see what others have said.
