Based on a newspaper poll, the Department of Finance (DOF) said only John Paolo Rivera of the Asian Institute of Management (AIM), and Emmanuel Lopez of the Colegio de San Juan de Letran, projected a lower rate of 4.5 percent and 4.7 percent, respectively, while 15 others placed their forecasts between 4.9 and 5.2 percent.
