Deriving NOI from audited financial statements

[Hasten Rudd]

Hello investors,

Question for you all. I'm hoping someone could help me out with suggestions in calculating the NOI of a real estate asset (in particular, hotels and apartment complexes) from a set of audited financial statements. I have several cash flow models for the assets that calculate NOI and I have income statements and cash flow statements and I am trying to get the NOI from these audited financial statements. I have been adding back depreciation/amortization, interest income, and as many other non operating expenses (and taking out as much non op income as possible). However, some of the financial statements I have at are prepared in accordance with IFRS or UK GAAP and are very vague in describing their line items one he income statement. Any suggestions?
