Philippine San Miguel's soft drink unit, Coca-Cola Bottlers Philippines (CCBPI), saw its first quarter consolidated operating income leap 77%, compared to the same period last year.

The results were driven by strong growth in sales volumes, itself the product of a period of aggressive marketing and good consumer demand.

Operating income from the company's Coca-Cola products alone reached around PHP285m, nearly four times the figure reported a year earlier.

Further numbers were not provided, however last year's operating income in the first quarter was reported as PHP246m. With these percentage increases operating income for this year's first quarter was likely to be close to PHP435m. CCBPI is a joint venture between San Miguel and the Coca-Cola Co.
