Nissan Motor Company (Tokyo: 7201) CEO Carlos Ghosn may step down before the start of the company's next mid-term business plan begins in five years, according to Bloomberg News Thursday.

At 58, Ghosn does not plan to commit to the next mid-term plan for Nissan, news which the company's investor-relations department has been slowly doling out to investors and analysts, according to Bloomberg News. Ghosn has served in the role of CEO at Nissan since 2006, the second longest of any chief executive at an automotive company.

Ghosn has said this is the last mid-term plan he'll commit to, meaning he may not stay here for the next mid-term period, Nissan spokesman Koji Okuda said, according to Bloomberg News.

Nissan Motor Company (Tokyo: 7201) shares rose 1.87 percent to 762 yen ($9.50) Thursday.
