  The Producer Price Index (PPI, 2000=100) for the manufacturing sector advanced to 1.4 percent in May 2011 from 1.3 percent in April, according to the preliminary results of the monthly Producer Price Survey. This was influenced by the double-digit annual growth posted by petroleum products (24.8%) and food manufacturing (10.1%). On the other hand, price decrements were reflected in six major sectors led by furniture & fixtures (32.2%). Refer to Tables 1 and 1-B.

  On a monthly basis, PPI went up to 0.2 percent in May 2011. This was due to the increases posted by eleven major sectors led by miscellaneous manufactures (2.9%). However, two sectors, petroleum products and textiles reflected decreases of -5.5 percent and -1.3 percent, respectively. Moreover, seven sectors continue to posts flat growth rates. Refer to Tables 1 and 1-B.

• Response Rate
  

  The response rate for May 2011 is 86.2 percent, which corresponds to the retrieval of 274 sample establishments? reports. Refer to Table 2.

• Technical Notes
  

  The National Statistics Office generates various price indices, one of this is the Producer Price Index. (PPI). The PPI is generated through the results of the Producers Price Survey (PPS) conducted nationwide. The survey gathers monthly actual producer prices of selected products included in the market basket.

  PPI utilizes the Paasche-type method of index computation with weights computed from the production concentration ratio of the Census of Philippine Business and Industry (CPBI)/ Annual Survey of Philippine Business and Industry (ASPBI). The weights are updated as soon as new results of the ASPBI/CPBI are available and applied at the beginning of each survey year.

  Hence, the weights of the major sectors and sub-sectors for the 2009 PPI were computed from the results of the 2006 CPBI for Manufacturing Establishments of total employment of 20 and over, which is the latest census results.

  Moreover, for industry classification, the 2010 PPI utilizes the amended 1994 Philippine Standard Industry Classification. There are 20 major sectors covered by the 2010 PPS with three consisting of subsectors.

  Non-responding sample establishments are estimated using cold-deck imputation method. Revisions to the preliminary estimates are done upon receipt of actual reports from late respondents.
