Deferred Maintenance

Deferred maintenance is the estimated cost to bring Government-owned property, plant, and equipment to an acceptable condition, resulting from not performing maintenance on a timely basis. Deferred maintenance excludes the cost of expanding the capacity of assets or upgrading them to serve needs different from those originally intended. The consequences of not performing regular maintenance could include increased safety hazards, poor service to the public, higher costs in the future, and inefficient operations. Estimated deferred maintenance costs are not accrued in the Statements of Net Cost or recognized as a liability on the Balance Sheets.

The amounts disclosed for deferred maintenance are allowed to be measured using one of the following three methods:

• Condition assessment surveys are periodic inspections of the Government-owned property to determine the current condition and estimated cost to bring the property to an acceptable condition.
• Life-cycle cost forecast is an acquisition or procurement technique that considers operation, maintenance, and other costs in addition to the acquisition cost of assets.
• Management analysis method is founded on inflation-adjusted reductions in maintenance funding since the base year.

The amounts disclosed in the table below have all been measured using the condition assessment survey method. The standards for acceptable operating condition and the changes in these standards and changes in asset condition vary widely between the Federal entities.

Some deferred maintenance has been deemed critical. Such amounts and conditions are defined by the individual agencies with responsibility for the safekeeping of these assets. The critical maintenance amount is not included in the low or high estimates amounts and is reported separately. Low and high estimates are based on the materiality of the estimated cost of returning the asset to the acceptable condition versus the total value of the corresponding asset.

Deferred Maintenance as of September 30, 2011, and 2010

Deferred Maintenance Cost Range
	Low Estimate		High Estimate		Critical Maintenance
(In billions of dollars)	2011	2010	2011	2010	2011	2010
Asset category:
Buildings, structures and facilities	31.3	129.7	36.4	134.8	97.6	95.0
Furniture, fixtures and equipment	0.1	4.7	0.1	4.7	2.5	4.5
Other general property, plant, and equipment	5.1	5.3	5.1	5.3	0.8	4.9
Heritage assets	0.9	1.9	0.9	1.9	1.2	1.6
Stewardship land	3.6	3.5	5.2	5.2	-	-
Total deferred maintenance	41.0	145.1	47.7	151.9	102.1	106.0

The low and high estimate amounts for 2011 are significantly lower than 2010 due to agencies’ incorrect reporting in 2010 that was not adjusted.

Please refer to the individual financial statements of DOI, DOD, USDA, and DOE for detailed significant information on deferred maintenance, including the standards used for acceptable operating condition and changes in asset condition.
