Related Party Transactions [Abstract]
Supervisory Services	Note E Supervisory Services Supervisory and other services are provided to Registrant by its supervisor, Malkin Holdings, a related party. Beneficial interests in Registrant are held directly or indirectly by one or more persons at Malkin Holdings and/or their family members. Registrant pays Supervisor for supervisory services and disbursements. The basic fee (the “Basic Payment”) had been payable at the rate of $40,000 per annum, payable $3,333 per month, since the fiscal year ended September 30, 1980. The Basic Payment was increased, with the approval of the Agents, by an amount equal to the increase in the Consumer Price Index since such date, resulting in an increase in the Basic Payment to $102,000 per annum effective July 1, 2010 to be adjusted annually for any subsequent increase in the Consumer Price Index. The Basic Payment was adjusted to $107,190 effective July 1, 2012. The fee is payable (i) not less than $2,333 per month, (ii) an additional $1,000 per month out of Primary Overage Rent and (iii) the balance out of available reserves from Secondary Overage Rent. Any deficiency in the portion of the fee payable from Primary or Secondary Overage Rent shall be payable out of Secondary Overage Rent in the next year in which Secondary Overage Rent is sufficient. The Agents also approved payment by Registrant, effective July 1, 2010, of the expenses in connection with regular accounting services related to maintenance of Registrant’s books and records. Such expenses were previously paid by Supervisor. Registrant pays Supervisor an Additional Payment equal to 10% of all distributions to Participants in any year in excess of the amount representing a return to them at the rate 15% per annum on their remaining cash investment in Registrant (which remaining cash investment at June 30, 2013 was equal to the Participants’ original cash investment of $3,600,000). For tax purposes, such Additional Payment is recognized as a profits interest, and the Supervisor is treated as a partner, all without modifying each Participant’s distributive share of reportable income and cash distributions. For the year ended December 31, 2012, the Additional Payment was $225,556. The basic supervisory services provided to Registrant by Supervisor include, but are not limited to, maintaining all of its entity and Participant records, performing physical inspections of the Building, providing or coordinating certain counsel services to Registrant, reviewing insurance coverage, conducting annual supervisory review meetings, receipt of monthly rent from Lessee, payment of monthly and additional distributions to the Participants, payment of all other disbursements, confirmation of the payment of real estate taxes, active review of financial statements submitted to Registrant by Lessee and financial statements audited by and tax information prepared by Registrant’s independent registered public accounting firm, and distribution of related materials to the Participants. Supervisor also prepares quarterly, annual and other periodic filings with the SEC and applicable state authorities. Due from Supervisor, a related party, was $60,000 at June 30, 2013 and December 31, 2012, respectively. Due to Supervisor, a related party, was $419,653 and $621,233 at June 30, 2013 and December 31, 2012, respectively. Registrant pays Supervisor for other services at hourly rates. Pursuant to the fee arrangements described herein, Registrant incurred supervisory fees of $63,595 and $62,851 the six-month periods ended June 30, 2013 and 2012, respectively. No remuneration was paid during the six-month periods ended June 30, 2013 and 2012 by Registrant to either of the Members. Included in professional fees are amounts for services from related parties of $30,230 and $73,602 for the three and six months month ended June 30, 2013, respectively, and $14,578 and $37,602 for the three and six months month ended June 30, 2012, respectively. Distributions are paid from a cash account held by Supervisor. That account is included in the condensed Balance Sheets as “Due from Supervisor.” The funds of $60,000 at June 30, 2013 and December 31, 2012 were paid to Participants on July 1, 2013 and January 1, 2013, respectively. Reference is made to Note C above for a description of the terms of the Lease between Registrant and Lessee. The respective interest, if any, of the Members in Registrant and in Lessee arise solely from ownership of Participations in Registrant and of Member interests or participations in Lessee. The Members as such receive no extra or special benefit not shared on a pro rata basis with all other Participants in Registrant or members in Lessee. However, all of the Members hold senior positions at Supervisor (which supervises Registrant and Lessee) and, by reason of their positions at Supervisor, may receive income attributable to supervisory or other remuneration paid to Supervisor by Registrant and Lessee.
