Help with Get-ADComputer

This is the bit I run

get-adcomputer -SearchBase "OU=Department,DC=Company,DC=de,DC=us" -filter "Passwordlastset -lt '2/7/2013'" -properties *| Select name,distinguishedName,passwordlastset | Export-Csv "C:\Report.csv" -notypeinformation

Using DistinguishedName it returns something like

Is it possible to to have it only return the OU's and not the DC's and CN? Or even better have it pull only the department OU information into the CSV?

I'm very new to PowerShell so any advice would be greatly appreciated.
