The license overdraft count is displayed in a separate column within the License Administration Console. The installed column displays both the purchased license total plus the associated overdraft total.
Overdraft usage is also visible in Studio. The license overdraft feature is offered as a convenience, not as a license entitlement. Any overdraft licenses used must be purchased within 30 days of first use.
Concurrent licenses and server licenses do not contain the overdraft feature. Citrix reserves the right to remove any overdraft feature in new product releases. The supplemental grace period enables unlimited connections to a product for 15 consecutive days. This feature is available to Citrix Virtual Apps and Desktops licenses.

If all licenses are in use, including the license overdraft where applicable, the supplemental grace period gives you time to determine why you exceeded the maximum license count and to purchase more licenses without disrupting your users.
After the supplemental grace period expires, normal connection limits are enforced. Users are not disconnected during active sessions.
As they disconnect, however, no new connections can occur until the license levels return to normal. The supplemental grace period is not automatically re-enabled once it completes. To re-enable the supplemental grace period, you must install another retail license, which grants a new day supplemental grace period if and when you exceed the subsequent maximum installed licenses limit.
We recommend that you allow the supplemental grace period to run out after it starts. To clear the warning condition do not add licenses immediately. Doing so gives you time to fully assess the situation and correctly address any issues.
If you install licenses while the supplemental grace period is in force, the License Server exits the supplemental grace period. Reenabling the supplemental grace period before fully determining the reason for the supplemental grace period, and how many licenses you require, might cause you to reenter the period after installing new licenses. Supplemental grace periods are granted per product version and edition and only for retail licenses. The supplemental grace period is enabled by default when you first install the licenses.
To disable the supplemental grace period feature, use the Citrix Licensing Manager. There is no way to track the total number of licenses consumed while in the supplemental grace period.

The on-premises subscription license is time bound for years and expires on a specific date. The license ceases to operate following the expiration date. The products offer everything that is available today with perpetual licenses. Your purchase includes both an on-premises subscription license and Customer Success Services Select service.
