This product is available through the Microsoft Open Value Program. This Open Value Paid Upfront sku means that you pay the amount of the license upfront. There are no other payments (unless you decide to add on additional terms of Software Assurance). Open Value gives you the rights to the license indefinitely. Software Assurance (SA) is included for the first three years which entitles you to any new editions that are released during those three years.

After your three year term, you have the option to add on another three year term of Software Assurance to continue with access to support and the latest versions.
