PART III -- NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,10-D, N-SAR,
N-CSR, or the transition report or portion thereof, could not be filed within
the prescribed time period.




SkyTerra Communications, Inc. (the "Company") is unable to file its Form 10-K
for the year ended December 31, 2005 without unreasonable effort or expense due
to delays caused by unanticipated effects arising from the recent spin-off
transaction (the "Transaction") of Hughes Communications, Inc. ("Hughes").

In connection with the Transaction, on December 31, 2005, the Company
contributed to Hughes substantially all of the assets and liabilities of the
Company other than its interests in each of Mobile Satellite Ventures LP and
TerreStar Networks, Inc. and certain designated cash. On February 21, 2006, the
Company made a special dividend distribution of all of the outstanding Hughes
common stock to the Company's stockholders. As a result of the Transaction,
Hughes became an independent, publicly-owned company and the accounting
successor to the Company.

The Company intends to file, by March 31, 2006, its Form 10-K for the year
ended December 31, 2005.
