The 190 partners of Goldman Sachs - Wall Street's most successful investment bank - will meet today to decide whether to go ahead with the company's flotation. Signs emerged at the weekend of growing unrest within the firm which may force a postponement. Stock market crises and the plummeting value of US investment banks would mean senior Goldman executives reap only half what they had hoped when the plan to float was drafted. US-based joint executive chairmen Jon Corzine and Henry Paulson would see the estimated value of their stakes slashed from US$1 billion - based on the price Goldman might have commanded at the market's peak - to $500 million at today's depressed prices. The bank's most senior British partner, London-based chief British economist Gavyn Davies was believed to have been in line for shares worth $85 million, but would see that fall to $42 million at present values. A Goldman spokesman confirmed the meeting but refused to comment on the outlook of the float. There have been widespread rumours of dissent regarding the November offering of 10 to 15 per cent of the bank because of market volatility and the dramatic slowdown in key profit areas, such as stock and bond issues. Share prices of Wall Street investment banks have plunged in the past two months and cautious markets could potentially wipe millions off Goldman's partners expected launch proceeds. Last month, the plan to take the company public was overwhelmingly approved and it filed a registration statement with the Securities and Exchange Commission. The initial public offering (IPO) has been valued between $25 billion and $30 billion, or four times its book value. Last week, Goldman reported pretax profits of $754 million in the third quarter, a decline of 19 per cent from last year's record-breaking $932 million. Trading and underwriting business has dipped, credit spreads have widened and a huge fall in global equity values has hit the financial services sector. Goldman is also one of the 11 firms bailing out failed Long-Term Capital Management and has taken $4 billion in losses from bets on global bond markets. The bank said it had no direct loans outstanding on the fund. Despite hard times, last week it dismissed suggestions of an IPO delay, claiming that the offer 'was on schedule'. If the float is postponed, it will not be the first time Goldman has stumbled at the starting post. Flotation has been considered no less than seven times in the past 27 years but, until now, it has always been rejected.
