Note that this mode is simply the combination of CTR and CBC-MAC,
though of course it's valuable to have a team of experienced
cryptographers give a precise specification of a good way of composing
them.  Some commentary by Rogaway can be found here:

all of his technical commentary seems indisputable, though of course I
would favour choosing less efficient modes over patent-encumbered
modes.
