Net income is likely to be 160 billion yen ($1.63 billion) in the 12 months through March, compared with its 148 billion yen estimate in July, the company said in a statement to Tokyo's stock exchange today. The maker of Camel and Mild Seven Cigarettes is seeking to expand overseas to offset a decline in its home market as the smoking rate falls and lawmakers consider higher tobacco taxes. Overseas cigarette sales have surged after last year's takeover of U.K.-based Gallaher Group Plc. ``Supported by strong performance in our international tobacco business, we are able to upwardly revise our sales and earnings forecasts,'' President Hiroshi Kimura said in a statement. Full-year sales are forecast to increase 7.2 percent to 6.87 trillion yen from a year earlier.
