Lehman Brothers Holdings Inc's Richard Fuld, the longest-serving chief executive on Wall Street, is under increasing pressure to seal an agreement for a capital infusion and unload hard-to-sell mortgage investments after the company's stock suffered a record decline on Tuesday.

Lehman, the fourth-largest US securities firm, issued a statement late on Tuesday, saying it will report third-quarter financial results yesterday at about 7:30 am in New York, a week earlier than planned.

The investment bank also promised to disclose "key strategic initiatives".
