CPI value at project closure

What should the CPI be after a project was closed (the project was not canceled)?
Must the CPI always move to 1 at project closure or could it remain at the last indicated value (example 0.85) before the project was closed?

We had a project and the week before the project was closed the CPI was 0.85. The project is now done and there will be no more work or costs. Should the CPI remain at 0.85?

CPI = EV / AC. It will not move automatically to 1. If the earned value is anything other than the actual cost, then it will not be 1.

SPI on the other hand has a mathematical loophole, and will automatically move to 1 when the planned scope of the project is completed, no matter how ahead or behind schedule the project because SPI = EV / PV. This is why Earned Schedule was introduced. The Earned Schedule SPI is measured in time rather than in money, and will continue to indicate how much the project was ahead or behind schedule even when all of the scope is completed. http://www.earnedschedule.com/Home.shtml

Hi Johan,

CPI is indicator of whether the project is under budget, on budget and over budget at any point of time. The CPI of 0.85 at completion indicates that project is over budget due to whatever reasons. This value will not change now as it is indicator that more cost was incurred to complete the project.

There may be several cases where SPI is more than 1 but CPI is less than 1 as these are to measure different dimensions.
Thanks
