HP Shares Fall After Accounting Change

Hewlett-Packard Co. shares fell 3.7% after the company reduced first-quarter cash flow from operations and said the personal-computer unit would have been profitable sooner without some costs.

Cash flow from operations, or cash Hewlett-Packard generated from selling computers, printers and services, was $647 million instead of the $791 million originally reported because of an accounting error, spokeswoman Rebeca Robboy said.

Shares of Hewlett-Packard dropped 57 cents to a four-month low of $15 on the NYSE.
