Then, as in Part I, and for comparison of tariffs derived from RPM application, tariffs
are calculated in the case of the postage stamp RPM and following the rules of the
CWD counterfactual.
\\
For postage stamp,
entry (resp. exit) tariffs are derived for each TSO by multi-
plying the allowed revenue augmented by the ITC amount and the new entry
(resp. exit) share of revenues, and dividing the result by the new total forecasted
entry (resp. exit) bookings. Tariffs are identical for all points in entry and all
points in exit: this is a result of postage stamp. The entry-exit split has changed
for both TSOs A and B, after the removal of former IPs, which explains why
tariffs will generally be different after the merger. For TSO B, which collects the
ITC in this example, tariffs will necessarily increase at all points compared to the
pre-merger situation, since an increased amount of revenues has to be collect-
ed from the same tariff charged at a reduced number of points. Therefore, at all
points, postage stamp tariffs for the TSO in charge of collecting the ITC revenue
always increase after the merger. The new tariffs are indicated in the table
below.

For CWD,
again it is necessary to consider distances between points, with the
same assumptions on distance calculations as before. Tariffs derived with the
CWD RPM are presented in the above table.
Compared to the pre-merger situation, the size of the distance matrices has
shrunk due to the removal of points.
