Leases [Abstract]
Lease	Note C Lease Registrant does not operate the Property. Registrant leases the Property to Lincoln Building Associates L.L.C. (“Lessee”) pursuant to an operating lease as modified (the “Lease”), which is currently set to expire on September 30, 2033. Lessee is a New York limited liability company whose members consist of, among others, entities for the benefit of members of Peter L. Malkin’s family. The Lease provides that Lessee is required to pay to Registrant as follows: (i) annual basic rent (“Basic Rent”) equal to the sum of $24,000 plus the constant annual mortgage charges on all mortgages. In accordance with the Ninth Lease Modification Agreement dated November 5, 2009, Basic Rent was increased to cover debt service on a $100,000,000 mortgage. See Note D. Basic Rent will be increased or decreased upon the refinancing of the mortgages provided that the aggregate principal balance of all mortgages now or hereafter placed on the Property does not exceed $100,000,000 plus refinancing costs. (ii) additional rent (“Additional Rent”) equal to, on an annual basis, the lesser of (x) Lessee’s net operating income (as defined) for the lease year ending September 30 or (y) $1,053,800 ($87,817 per month) and further additional rent (“Further Additional Rent”) equal to 50% of any remaining balance of Lessee’s net operating income for such lease year. Lessee has no obligation to make any payment of Additional Rent or Further Additional Rent until after Lessee has recouped any cumulative operating loss accruing from and after September 30, 1977. There is currently no accumulated operating loss against which to offset payment of Additional Rent or Further Additional Rent. The Lease also requires an advance against Additional Rent, equal to, on an annual basis, the lesser of (x) Lessee’s net operating income for the preceding lease year or (y) $1,053,800 which is recorded in revenue in monthly installments of $87,817, which, in the latter amount, will permit basic distributions to Participants at an annual rate of approximately 14.95% per annum on their original and remaining cash investment of $7,000,000 in Registrant; provided, however, if such advances exceed Lessee’s net operating income for any lease year, advances otherwise required during the subsequent lease year shall be reduced by an amount equal to such excess until Lessee shall have recovered, through retention of net operating income, the full amount of such excess. After the Participants have received distributions equal to a return of 14% per annum, $7,380 is paid to Supervisor from the advances against Additional Rent. Lessee is required to make an annual payment to Registrant of Further Additional Rent, which, as explained above, is the amount representing 50% of the remaining net operating income reported by Lessee for the lease year ending September 30th after deducting the advance against Additional Rent. The Lease requires that the report be delivered by Lessee to Registrant annually within 60 days after the end of each such lease year. Registrant recognizes Further Additional Rent when earned from the Lessee at the close of the lease year ending September 30^th and records such amount in revenue in the three months ended September 30th. Rent income, earned from a related party, was $4,275,512 and $4,264,100 for the six months ended June 30, 2013 and 2012, respectively. For the lease year ended September 30, 2012, Lessee had net operating income of $12,466,335. Lessee paid advances against Additional Rent of $1,053,800 for that lease year prior to September 30, 2012 and Further Additional Rent of $5,706,265 subsequent to September 30, 2012. The Further Additional Rent of $5,706,265 represents 50% of the excess of the Lessee’s net operating income of $12,466,335 over $1,053,800. After deducting $2,500,000, mainly for fees relating to (i) a proposed consolidation of Registrant, other public and private entities supervised by the Supervisor and the Supervisor and certain affiliated management companies into Empire State Realty Trust, Inc., a newly formed real estate investment trust (collectively the “Consolidation”) and the initial public offering of Class A common stock of Empire State Realty Trust, Inc. (the “IPO”), and for the increase in the supervisory fee to Supervisor, accounting fees and general contingencies, (ii) the annual NYS filing fee of $3,000, and the (iii) additional payment to Supervisor of $320,327 (representing the additional payment, as defined in Note E, of $327,707 less $7,380 previously paid), the balance of $2,882,938 was distributed by Registrant to the Participants on December 12, 2012. The Supervisor of the Registrant has solicited consents of Participants in the Registrant and other public limited liability companies supervised by the Supervisor to the proposed Consolidation pursuant to a prospectus/consent solicitation statement included in a registration statement on Form S-4 declared effective by the SEC. In the proposed transaction, (x) the property interests of the Registrant, such other public limited liability companies and certain private entities supervised by the Supervisor, and (y) the Supervisor and certain affiliated management companies would be contributed to the operating partnership of Empire State Realty Trust, Inc., a newly organized real estate investment trust. Consents are required from Participants in the Registrant and such other public limited liability companies for them to contribute their interests in the Consolidation. The Supervisor of the Registrant has received the required consents of Participants in the Registrant to the Consolidation. The Supervisor has also received the required consents of participants in 250 West 57^th St. Associates L.L.C. to the Consolidation. The Supervisor has received the required supermajority consents from participants in Empire State Building Associates L.L.C. Following the receipt of the required supermajority approval, each participant in Empire State Building Associates L.L.C. who had voted against, or abstained, or not submitted a consent form regarding the Consolidation, was sent a 10-day buyout notice stating that its interest was subject to buyout for $100 if it did not consent to the Consolidation. The period for consenting to the Consolidation for those sent the buyout notice, as extended, has not yet terminated. Consents have been obtained from participants in the private entities and the Supervisor and certain affiliated companies and affiliates of the Supervisor for them to make such contributions. The consideration to be paid to the contributing companies and entities in the Consolidation will be allocated in accordance with exchange values determined based on appraisals by an independent third party.
