The Company's third quarter revenue of $44.2 million reflects an increase of $12.6 million (40%) from the same period last fiscal year. The quarter to quarter increase largely results from higher work volumes primarily attributable to work for the Navy on the aircraft carrier USS Lincoln.
Revenues for the first nine months of fiscal year 2007 of $80.8 million reflect a decrease of $88.4 million (52%) from the comparable period of fiscal year 2006. The revenue decrease in the first nine months of fiscal year 2007 is primarily attributable to reductions in Navy and Coast Guard volumes. The majority of the Company's Navy work volumes are associated with vessel availabilities executed under multi-year option contracts. In the first nine months of the prior year, revenues were favorably impacted by overhaul work on the Navy aircraft carrier USS Stennis, post shakedown availability work on the Navy destroyer USS Momsen, the scheduled service availability (docking) of the Navy frigate USS Ford and the planned maintenance availability (docking) of the U.S. Coast Guard Polar Sea icebreaker, all of which completed prior to the current fiscal year. In contrast, the first nine months of the current year coincided with planning and overhaul work on the aircraft carrier USS Lincoln and lower volumes associated with work for the Coast Guard on the Polar Star and Healy icebreakers.
