Oracle ERP/CRM Useful Life?

To Finance/Accounting Oracle ERP/CRM Users - My company is going live with Oracle ERP/CRM in the next year and I'm trying to benchmark the useful life to use for the Oracle implementation asset on our books.

If any of you who read this, can ask the accountants at your company if you don't know this yourself, I would greatly appreciate it!

The more responses I receive, the stronger my conclusion. I would greatly appreciate feedback. Thank you!
