The latest quarter included a $155 million charge for the broadband migration, a $135.9 million pretax gain on derivative instruments, and a net gain on investments of $71.4 million. Revenue rose 14% to $1.08 billion from $945.9 million a year earlier. The loss was in line with analysts' estimates.
