Shelf Registration Statement [Abstract]
Shelf Registration Statement	12. Shelf Registration Statement: In October 2009, the Company filed a shelf registration statement with the Securities and Exchange Commission. The registration statement, which became effective on January 4, 2010, provides the Company with advance regulatory approval to sell securities in one or more separate offerings in amounts and at prices and terms to be determined at the time of sale. The registration statement is intended to provide the Company with flexibility to raise up to $200,000 from the offering of a variety of equity or debt securities, including common shares, from time to time. If securities are issued, the Company may use the proceeds for funding acquisitions, capital expenditures, working capital, reducing or refinancing debt or general corporate purposes.
