Financial Services & Reporting

Financial Reports

Tiarna can customize reports to the needs of our clients. All financial reporting activity is consolidated on a monthly basis. Financial reports are delivered to our clients each month, bound with the table of contents that identifies the activities of the previous month. Variances between actual and budget numbers are identified and explained through detailed narrative. Ongoing operations such as capital improvements, leasing activities or possible litigation are identified for reference and status purposes.

Annual Budgets

Our clients receive an annual budget that identifies the projected operations, capital expenditures and leasing activity for each asset. This budget identifies detailed explanations for all sources of income, operating expenses, capital expenditures, and owner expenditures for the coming calendar year. This plan is submitted in person by Tiarna’s Project Team for detailed review with our client. A final budget is bound and distributed in hard copy along with an electronic version with key tabs for easy access to project data.
