Toyota Motor Corp., poised to lose its crown as the world’s largest carmaker this year, cut its profit forecast 54 percent after Thailand’s worst floods in almost 70 years disrupted output of Camry and Prius vehicles.

Net income will fall 56 percent to 180 billion yen ($2.3 billion) in the 12 months ending March 31, the Toyota City, Japan-based carmaker said in a statement yesterday.
