Bausch & Lomb (BOL) on Tuesday barred Chairman Ronald Zarrella from receiving bonuses in 2002 after the executive apologized for misrepresenting his academic background in his official biography. However, the board of the optics company said it would allow Zarrella, who offered to resign, to stay on in his post as CEO and chairman. His contract had guaranteed him at least $1.1 million in bonuses this year. On Oct. 18, Zarrella admitted that his resume falsely said he earned an MBA from New York University. Maxim Integrated Products (MXIM) reported fiscal first-quarter financial results that met Wall Street's expectations. Orders declined during the quarter, but Maxim said gross margin should improve during the second quarter due to cost cuts. Micromuse (MUSE) reported fiscal fourth-quarter revenue of $25 million and a net loss of $56.4 million, or 75 cents a share. Excluding items, the San Francisco business software firm reported a loss of $7.3 million, or 10 cents a share. Analysts polled by Thomson First Call were looking for a loss of 11 cents a share, on average. That estimate was revised following a warning from Micromuse on Oct. 9 when it scaled back its pro forma outlook due to weak spending conditions and ongoing structural changes in its target markets. Ahead of the report, shares were down 11 percent Tuesday and gained a nickel after hours on Island ECN. Sanmina on Tuesday reported a more than 15-fold increase in its fourth-quarter net loss from a year ago, mainly due to a $2.7 billion goodwill impairment charge mandated by changes in accounting rules. The electronic components contract manufacturer (SANM) reported a net loss of $2.6 billion, or $5.10 a share. A year ago, it had a net loss of $167.8 million, or 52 cents.
