IBM is under investigation by the US Securities and Exchange Commission over its first quarter profits and the way it accounted for compensated stock options in its financial report.
Some analysts had expected the stock options to be worth more than was reported at the time of the results, and the SEC has been brought in to investigate.
IBM reported profits below Wall Street expectations, and the company decided to launch a fierce cost-cutting programme, including 13,000 job cuts in western Europe and the US.
The firm courted more controversy by soon afterwards revealing plans to hire an additional 14,000 workers in India this year.
IBM said the “informal” SEC investigation did not imply any wrongdoing on its part.
