The financial records are comprised of financial reports, tax documents, commission files, escalation records, office administration accounts, and supporting materials. These documents offer fiscal information on several Uris business endeavors, including 300 Park Avenue, 380 Madison Avenue, 485 Lexington Avenue, and 750 Third Avenue. Occasionally, the records contain figures for the Uris Brothers Foundation and family member trusts. Audits, balance sheets, budgets, collection statements, and weekly reports demonstrate the general performance of these ventures. Several files contain publications, forms, instructions, and correspondence for federal, state, and city taxes. There are also tentative assessment valuations and applications for reductions for Real Estate taxes. The commission records for various tenants have agreements, bills, and correspondence with brokerage firms. Calculation worksheets, correspondence, and sample lease clauses detail how escalations for electricity, labor, and real estate taxes were determined and then passed on to the tenants. The rest of the financial records describe the costs associated with office administration and professional services shared by different corporate entities. Inclusive office operating expenses and bank accounts are presented in memorandums, reimbursement records, lists, and forms. Additional correspondence, agreements, and accounting worksheets calculate the fees spent on attorneys, accountants, insurance, bank accounts, and tenant management.
