Your comments seem to reveal a method to track the income to the BYC entity.
If you trace the BTB taxes for the property, which should be public record, you can then extrapolate the gross revenues for the time frames examined. Further, the monies are due and payable monthly, so the breakdown is already segmented for evaluation.
There is no need to sit back and wait for a report that is late in coming to you, take some proactive steps, enforce your contract with the help of the local court by demanding the income that has not been paid to you. If you are procedural in your invoice to the BYC entity, the documentation is difficult to ignore. Invoice the company with due diligence and when they default, sue them using the civil process.
