Legal Proceedings [Abstract]
LEGAL PROCEEDINGS	NOTE 9 — LEGAL PROCEEDINGS Kayne Litigation — On July 7, 2011, the Company was served with an amended complaint (the “Complaint”) filed in the United States District Court for the Central District of California alleging, among other things, that the Company, certain of its present and former directors and other entities or individuals now or previously associated with Grande, intentionally interfered with the ability of the plaintiffs to collect on a judgment (now approximately $47 million) they had against Grande by engaging in transactions (such as the dividend paid to all shareholders in March 2010) which transferred assets out of the United States. The Complaint also asserts claims under the civil RICO statute and for alter ego liability. In the Company’s opinion, based on an initial review, the claims appear to be devoid of merit. Accordingly, on September 27, 2011, Emerson moved to dismiss the action for failure to state a claim (the “Motion”). The Court has scheduled oral argument for the Motion for December 19, 2011. In the interim, and in the event that the Motion is denied, Emerson intends to defend the action vigorously. Except for the litigation matters described above, the Company is not currently a party to any legal proceedings other than litigation matters, in most cases involving ordinary and routine claims incidental to our business. Management cannot estimate with certainty the Company’s ultimate legal and financial liability with respect to such pending litigation matters. However, management believes, based on our examination of such matters, that the Company’s ultimate liability will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Kayne Litigation — On July 7, 2011, the Company was served with an amended complaint (the “Complaint”) filed in the United States District Court for the Central District of California alleging, among other things, that the Company, certain of its present and former directors and other entities or individuals now or previously associated with Grande, intentionally interfered with the ability of the plaintiffs to collect on a judgment (now approximately $47 million) they had against Grande by engaging in transactions (such as the dividend paid to all shareholders in March 2010) which transferred assets out of the United States. The Complaint also asserts claims under the civil RICO statute and for alter ego liability. In the Company’s opinion, based on an initial review, the claims appear to be devoid of merit.
