Microsoft Office for Mac License through Open Value Licensing
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. Software Assurance also includes 24x7 support and exclusive access to
Microsoft E-learning Online. 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.
