The February 2013 offer represented a small premium over the then-current stock price, much lower than the stocks all-time high of $65 USD per share reached during the dotcom bubble in 2000, as well as its July 2005 price of $40 USD which was the high-water mark of the post-dotcom era. The price of $13.65 per share represented a 25% premium to the stock price, but far below the 52-week high of $18.36, and more than 76% off its all-time high. Several major institutional shareholders have voiced opposition, including Southeastern Asset Management and Mason Hawkins. Michael Dell owns the largest single share of the companys stock and was part of negotiations to go private, but only offered $750 million of his own money for a deal that would involve almost $16 billion in new debt. T. Rowe Price, which has the third largest holding, also objected to the low price of the proposal. Southeastern Asset Management, the largest shareholder of Dell stock with about 8.5%, is opposed to the deal at the per share price of $13.50 to $13.75 as they value the company at $23.72 a share. Southeastern also complained that the overseas funds arent offered to sweeten the buyout offer.. How many dollars higher was the all time high stock price than the price in February 2013 price and the 52-week high combined?
