NEW YORK, Nov 17 (Reuters) - U.S. stock index futures slipped on Monday, following four consecutive weeks of gains for major Wall Street indexes, weighed by data showing Japan slipped into recession.
* Merger and acquisition news partly offset the declines as Halliburton said it would buy Baker Hughes and Allergan is close to a buyout deal by Actavis.
* Japan's economy unexpectedly slipped into recession in the third quarter, setting the stage for Prime Minister Shinzo Abe to delay an unpopular sales tax hike and call a snap election two years before he has to go to the polls.
* The Japanese data took crude futures prices lower, with Brent off 1 percent at $78.50 per barrel. Brent prices have fallen in the last eight weeks and are down nearly 30 percent from June.
* Baker Hughes rose 16.4 percent on news Halliburton would acquire it in a cash and stock transaction of about $34.6 billion. Halliburton shares fell 2.9 percent in premarket trading.
* Allergan added 4.5 percent as the Actavis buyout values the company as high as $65.5 billion.
* Negotiations between Hasbro and DreamWorks Animation have been hampered by issues regarding the structure of the combined company, according to a person familiar with the matter. DreamWorks shares fell 13.3 percent.
