As a key economic leading indicator, the PMI of non-manufacturing sector fell to 57 percent in June from 61.9-percent increase in May, CFLP said.

A reading above 50 percent indicates expansion while below 50 percent indicates contraction.

The PMI for non-manufacturing sector was 62.5 percent in April, 60.2 percent in March, 44.1 percent in February and 56.4 percent in January.
