Earlier this month, HP said it would take a $8 billion "impairment of goodwill" writedown against its services division. "Goodwill" refers to less tangible assets, such as brand strength, that are considered when figuring out a company's total value. HP's $13.9 billion acquisition of services provider EDS has been roundly criticized as too costly.

HP also said earlier this month that it would have a bigger than expected charge in the third quarter in connection with a workforce reduction plan announced earlier this year.

Revenue for the third quarter fell 5 percent year over year to $29.7 billion.

Without the writedowns and other one-time costs, third-quarter profits would have been $1.97 billion, down 9 percent year-over year.

Excluding one-time costs, full-year earnings per share will be $4.05 to $4.07. In May, HP said it expected full-year earnings of $4.05 to $4.10 per share.
