When you activate a new Panda license, you can combine it with an existing license to synchronize renewal dates. The activation process merges the new license with the selected license and the two licenses are co-terminated, or co-termed. This makes it easier to manage and renew your licenses.

Co-termed licenses are merged together and a new expiration date is calculated based on your updated license count and the term length of the license you activated.

End-Users

If you have an end-user account, each time you activate a Panda license key, your new license is automatically co-termed with your current active license. End-user accounts can only have one license per product.

Partners

If you have a WatchGuard Partner account, only NFR licenses are co-termed. All other licenses are activated immediately as pool licenses. For pool licenses, the expiration date is determined when you assign the license.

## Renewal Date Calculation for Co-Termed Licenses

Here is the calculation used to determine the expiration date when two licenses are co-termed:

### Example 1 — Add Endpoints

You have a license for 20 endpoints that expires in 45 days, and you want to add 10 endpoints on a 1 year license (you purchased 10 endpoint licenses with a 1 year term length). To do so, you activate your license and select Add Users in the license activation wizard.

To calculate the new expiration date for your license, we can use the co-term calculation formula with these values:

• Current license count = 20
• Days until license expires = 45
• Purchased license count = 10
• Term days for purchased endpoint licenses = 365
• Final license count = 30 endpoints (20 + 10)

When we calculate the value in the formula above, we get 4,550 ÷ 30 = 151.67. We round this value up to 152. So the new expiration date for 30 endpoints is 152 days from the activation date of your new license.

### Example 2 — Add Endpoints on a License with a Different Term Length

You have a 1 year license for 10 endpoints that expires in 200 days, and you want to add 50 endpoints on a 3 year license (you purchased 50 endpoint licenses with a 3 year term length). To do so, you activate your license and select Add Users in the license activation wizard.

To calculate the new expiration date for your license, we can use the co-term calculation formula with these values:

• Current license count = 10
• Days until license expires = 200
• Purchased license count = 50
• Term days for purchased endpoint licenses = 365 x 3
• Final license count = 60 endpoints (10 + 50)

When we calculate the value in the formula above, we get 56,750 ÷ 60 = 945.83. We round this value up to 946. So the new expiration date for 60 endpoints is 946 days from the activation date of your new license.

To calculate the new expiration date for your license, we can use the co-term calculation formula with these values:

• Current license count = 100
• Days until license expires = 10
• Purchased license count = 150
• Term days for purchased endpoint licenses = 365
• Final license count = 150 endpoints (100 renewed + 50 added)

When we calculate the value in the formula above, we get 55,750 ÷ 150 = 371.67. We round this value up to 372. So the new expiration date for 150 endpoints is 372 days from the activation date of your new license.

### Example 4 — Renew a License After Expiration

You have a license for 100 endpoints that expired 10 days ago, and you want to renew your license for another year (you purchased 100 endpoint licenses with a 1 year term length). To do so, you activate your license and select Extend License in the license activation wizard.

To calculate the new expiration date for your license, we can use the co-term calculation formula with these values:

• Current license count = 100
• Days until license expires = −10
• Purchased license count = 100
• Term days for purchased endpoint licenses = 365
• Final license count = 100 endpoints

When we calculate the value in the formula above, we get 35,500 ÷ 100 = 355. So the new expiration date for your 100 endpoints is 355 days from the activation date of your new license (the term length of your new license minus the 10 days).

### Example 5 —Renew a License with Fewer Endpoints

You have a license for 100 endpoints that expires in 10 days, and you want to renew your license for another year with only 80 endpoints (you purchased 80 endpoint licenses with a 1 year term length). To do so, you activate your license and select Extend License in the license activation wizard.
