(Bloomberg) -- Sony Corp. said it intends to take full control of its finance unit for about 395.5 billion yen ($3.7 billion), buying out one of its most lucrative businesses to inject more stability into a largely electronics and entertainment-focused operation.The Japanese giant will offer 2,600 yen a share for the part of Sony Financial Holdings Inc. it doesn’t already own, it said in a statement Tuesday.

Sony Financial itself was set up in 2004 and at one point was expected to bring in the majority of the Japanese conglomerate’s operating profit.“The move could help stabilize Sony’s profit even when electronics businesses are in trouble,” Morningstar Research analyst Kazunori Ito said.
