Commitments and Contingencies Disclosure [Text Block]	Contingencies On March 15, 2011, a lawsuit asserting derivative claims on behalf of the Partnership was filed in the Supreme Court of the State of New York, County of New York, against Virgin Media Inc., ntl (B) Limited and the General Partner. The complaint generally asserts that the General Partner, Virgin Media Inc., and ntl (B) Limited have breached their fiduciary duties and/or aided and abetted such breach in pursuing the Asset Sale at a price that allegedly undervalues NTL South Herts. The plaintiff claims that the appraisals which were obtained fail to value NTL South Herts properly and are stale because they are dated as of September 30, 2010 and do not reflect market changes since that date. The complaint further asserts that the transfer by NTL South Herts of premium television services to a Luxembourg affiliate of Virgin Media Inc. in 2009 deprived NTL South Herts of a valuable asset. The complaint asserts breach of fiduciary duties, breach of contract and unjust enrichment, and seeks an accounting in respect of the general allocation of expenses to NTL South Herts. Among other remedies, the plaintiff seeks an order directing the General Partner to exercise its fiduciary duties, the imposition of a constructive trust upon any benefits improperly received, an order of an accounting and an award of costs, including attorney’s fees. On October 28, 2011, the parties presented to the court a Settlement Agreement, subject to court approval, under which the Partnership would be paid an additional $1.25 million (the "settlement amount") for the Asset Sale. Except for such fees and expenses as the court may award to the plaintiff's counsel, which is proposed to be a maximum of 30% of the Settlement Amount ($375,000), the proceeds would be used solely for the benefit of the limited partners of the Partnership. The court has scheduled a final hearing for January 17, 2012 to review and approve the settlement, and limited partners will receive a separate notice by mail describing the settlement in greater detail. The primary exposure to loss for the Partnership is in respect to its obligation to indemnify, in certain circumstances, the General Partner and certain of its affiliates. No accrual has been recorded for the indemnification as the amounts are not estimable. Because this is a derivative claim, any recovery made will be for the benefit of the
