Field Name

Function

Installation Date

Enter the date the node was installed.

Asset Life

Enter the number of years that the node is expected to be used before being retired.

Asset Cost

Enter the amount of money the node cost when purchased

Salvage Value

This is how much money the node can be sold or salvaged for.

Replacement Date

This the date that the node should be replaced.

Present Value

The current worth of the Building, auto-calculated using the following method:

• Determine the number of Months of Service Life (MSL):  Asset Life*12 = MSL
• Determine the date of Last Full Month (LFM) by noting the current date and determining the last day of the previous month. For example, if System Date = 4/7/2005 then LFM = 3/31/2005; if System Date = 3/31/2005 then LFM = 2/28/2005.
• Determine the First Month of Depreciation (FMD) by looking at the Installation Date. If the Installation Date is during the first half of the month (14th and before) that month is used. If the Installation Date is during the second half of the month, the system considers the next month the FMD. For example, an Installation Date of 4/14/2001 would set the FMD to 4/1/2001. An Installation Date of 4/16, 2001 would be set to 5/1/2001.
• Determine the Months of Depreciation (MD): LFM - FMD = MD
• Final calculation: [MD(Asset Cost - Salvage Value)]/MSL = Present Value

Remaining Life

Reflects the remaining life (in years) of the node.

Number of days left calculated based on Replacement Date - Installation Date = Days Left.

Days Left / (Salvage Life/365) = Remaining Life

Criticality

Rates how important the asset is. This rating should be a whole number based on a scale that the agency uses. A higher number means more risk.

Example: On a scale of 1 to 100 this asset is pretty import so it has a Criticality score of 85.

Probability of Failure

Rates how likely the asset is to fail. This rating should be less than one because it represents a percentage.

Example: This asset will only fail about 5% of the time so it has a Probability of Failure of (5/100) = .05

Mitigation

Rates any factors that have been put into place to mitigate the failure of the asset. This rating should be less than one because it represents a percentage.

Example: To offset the failure of this asset we have a backup, though it will only make up for about 30% of the loss. This asset has a mitigation score of (30/100) = .3

Risk

Represents how much risk the asset represents. Calculated based on: (Consequence of Failure x Probability of Failure x Mitigation).

Example: This asset represents a 85 x .05 x .3 = 1.275 risk to the system.
