Goldman Sachs has been sued by a Manhattan landlord who alleged the bank violated the terms of its rental agreement by failing to share profits from a sublease of the space.

The lease for 180 Maiden Lane required Goldman Sachs to share 50% of any profit it might make from subleasing the property to a third party, according to the complaint filed Aug. 26 in New York state court by developer Joseph Moinian’s Almah, a company he controls and which owns the building.

Moinian was told by Goldman that the profit-sharing requirement didn’t apply to its sublease deal with American International Group Inc. because Goldman didn’t receive any money from AIG, according to the complaint. Moinian says the lease’s value is $150m and the suit seeks $75m.
