How can I display the password expiration date for a user

Question

I have created a GUI (using PrimalForms) which runs powershel scripts to pull information like user ID, email address, last logon ec. for the helpdesk to help establish the validity of some user claims of "it worked yesterday" and the like.
I have been asked to add the password expiration date, but I am struggling to get the code for this addition.
Does anyone know how I can include this, and have it in a human readable format?
The current scripts (there are 3) allow the helpdesk staff to search on user ID and display name, the third provides the last logon, it was impossible to include this in the other scripts so I added an extra search button and called it good. An example of
these scripts is below (please note, PrimalForms needs a slightly different syntax in order to get the results displayed, but the core script is standard PS, I use Powershell 3.0)
$results.Text=Get-ADUser -Filter "sAMAccountName -eq '$($EntryBox.text)'" -Properties DisplayName, sAMAccountName, mail, extensionattribute5, PasswordLastSet, PasswordExpired, PasswordNeverExpires, buMemberOf, telephoneNumber, msExchOmaAdminWirelessEnable, whenCreated, whenChanged, enabled, AccountExpirationDate | select givenName, surname, DisplayName, sAMAccountName, mail, extensionattribute5, PasswordLastSet, PasswordExpired, PasswordNeverExpires, buMemberOf, telephoneNumber, msExchOmaAdminWirelessEnable, whenCreated, whenChanged, enabled, AccountExpirationDate | Out-String
$results.Focus()
for info:
$results.text is the window in the GUI results are displayed  in
$entrybox.text is the text box the helpdesk staff use to input the user ID or display name of the account they are querying
$results.focus simply tells the script to put the results in the results.text window
The screenshot below shows the current setup, this is purely to put the above information into perspective. Obviously some of the information displayed has been removed/redacted along with our logo.

Hi,
Here's an example you can build from:
$maxPasswordAge = 120
Get-ADUser USER -Properties PasswordLastSet |
Select SamAccountName,
PasswordLastSet,
@{N='PasswordLifeRemaining';E={$maxPasswordAge - ((Get-Date) - $_.PasswordLastSet).Days}},
@{N='PasswordExpirationDate';E={(Get-Date $_.PasswordLastSet).AddDays($maxPasswordAge)}}
