Subsequent Events [Abstract]
Subsequent Event	SUBSEQUENT EVENT On April 3, 2019, the Board approved and the Company entered into a Second Amendment to the Rights Agreement, which amends the Rights Agreement, dated as of April 6, 2016, between the Company and Computershare Trust Company, N.A. and Computershare Inc., as rights agent, as amended by the First Amendment to the Section 382 Rights Agreement dated as of February 14, 2017 (the “First Amendment”). The Second Amendment, among other things, (i) decreases the purchase price for each one one-thousandth (1/1000th) of a share of the Company’s Series A Participating Cumulative Preferred Stock, par value $1.00 per share, from $26.00 to $18.00 and (ii) extends the Final Expiration Date (as defined in the Rights Agreement) from April 5, 2019 to April 5, 2022. The Second Amendment was not adopted as a result of, or in response to, any effort to acquire control of the Company. The Second Amendment has been adopted in order to preserve for the Company’s stockholders the long-term value of the Company’s net operating loss carry-forwards for United States federal income tax purposes and other tax benefits.
