positive revenue to expenditure ratios may not always be as favorable as they appear/

The county has not been depreciating its infrastructure system.
1. What reservations might you have as to the significance of the county excess of revenues over expenditures in 2012?
2. Suppose that you were the county independent auditor. What reservation might you have as to the county reporting practices?
3. Suppose that the county is required to depreciate its roads. As of year-end 2012, the estimated initial cost of the roads is $100 million, and their estimated useful life is 40 years. How does the change from the modified approach to the standard approach affect the county general fund excess of revenues over expenditures? How does it affect the count government-wide statements?
