Most, if not all, Tennessee counties report their infrastructure on an individual asset basis. However, the GASB allows for a modified approach for infrastructure reporting. Under the modified approach, counties still are required to perform an initial retroactive capitalization of county-owned infrastructure (if over the $10 million threshold mentioned previously). However, instead of annually depreciating each infrastructure asset, the county must calculate a “maintenance of effort” amount that reflects the current costs for preserving infrastructure in lieu of depreciation. Counties are discouraged from implementing the modified approach since use of this method requires a county to periodically engage independent engineering consultants to perform condition assessments and demonstrate that all infrastructure has been maintained at or above a prescribed level.
