Here's the source from FiringSquad.com:
FiringSquad said:Take Two Interactive has finally released its financial numbers for its fiscal 2006 time period (which ended Oct. 31, 2006). The company delayed releasing its numbers until its stock options investigation was completed. For the 2006 fiscal year, Take Two had $1.036 billion in revenue, a slight drop from $1.201 billion in revenue from the 2005 fiscal year. Take Two suffered a net loss of $184.9 million for the fiscal 2006 year compared to a profit of $35.3 million for the 2005 fiscal year. The company said its losses were due to several factors, including the trasition from current to next-gen consoles and higher game development costs. Take Two went over a list of games expected to be released in their 2007 fiscal year, all of which were previously announced. The press release also stated that in their 2008 fiscal year (which begins Nov. 1 2007), they plan to release a new game in their Civilization strategy game series.
