           Future increases in satellite and transmission expenses will primarily be attributable to the launch and operation of new satellites, the addition of new terrestrial repeaters and maintenance costs of existing terrestrial repeaters. We expect to deploy additional terrestrial repeaters in 2007 and 2008 if we obtain the necessary regulatory approvals. Such expenses may also increase in future periods if we decide to reinstate our in-orbit satellite insurance.
