Basis of Presentation and General Information, Description	As of June 30, 2012, we owned and operated a modern fleet of 45 oceangoing vessels comprised of 43 Supramax and 2 Handymax vessels with a combined carrying capacity of 2,451,259 dwt and an average age of approximately five years. In 2011, we completed our Supramax vessel newbuilding program.
Stockholders' Equity, Reverse Stock Split	Effective as of the opening of trading on May 22, 2012, the Company completed a 1 for 4 reverse stock split as previously approved by the Company's shareholders. Proportional adjustments were made to the Company's issued and outstanding common stock and to its common stock underlying stock options and other common stock-based equity grants outstanding immediately prior to the effectiveness of the reverse stock split to reflect the reverse stock split. No fractional shares were issued in connection with the reverse stock split, as shareholders who would otherwise hold a fractional share of common stock received a cash payment in lieu of that fractional share. All references herein to common stock and per share data have been retrospectively adjusted to reflect the reverse stock split.
