Apple Inc Chief Executive Steve Jobs is back to work following a near six-month medical leave, the company said on Monday.

Steve is back to work, a company spokesman said. He's currently at Apple a few days a week, and working from home the remaining days. We are very glad to have him back.

In January, after initially blaming his noticeable weight loss on a hormone imbalance, Jobs announced he was taking a temporary leave of absence, saying his health-related issues were more complex than he had originally thought.

Jobs, 54, was treated for a rare form of pancreatic cancer in 2004.

He underwent a liver transplant in Memphis, Tennessee, while on leave. Although the hospital did not provide further details of his condition, it said he is now recovering well and has an excellent prognosis.

Shares of Cupertino, California-based Apple did not immediately react to the news. They were up 62 cents at $143.06 in Nasdaq trading.
