Ex-Salomon Trader Expected to Plead Guilty: Paul Mozer, former head of the government trading desk at Salomon Bros., is expected to plead guilty today to two felony counts of lying to Treasury officials in a plea agreement with federal prosecutors in New York. Mozer still faces a civil suit brought by the SEC accusing him of overbidding in eight Treasury auctions. As a result of Mozer’s bids, Salomon controlled about 57% of the February, 1991, Treasury auction. Rules prohibit any one firm from controlling more than 35%. Separately, Salomon has agreed to pay $4 million to settle claims by 39 states and the District of Columbia for its role in the 1991 Treasury bond auction scandal, regulators said.
