OCTOBER LEAGUE: DDB takes the lead, PHD remains on top of media

METHODOLOGY: The Business Performance Leagues are compiled, but not audited, by Campaign Asia-Pacific magazine with the assistance of PricewaterhouseCoopers Hong Kong on a monthly basis and are based on aggregated billings data submitted by the agencies. Business performance is measured according to the annualised billings value of accounts won and lost. Agencies are ranked according to their net billings gain in the year to date.

It is assumed that the annualised billings data submitted by the agencies is complete, accurate and valid as per the agreed methodology and no audit is performed on this information. The methodology is that, for accounts that do not have a billings figure attached to them, a billings score is calculated as fees multiplied by 6.5 (a standard industry multiplier). Where billings data is submitted in ranges, the mid-point is selected for compiling the leagues. Retained business is not included.

Where possible, information submitted by agencies is validated for accuracy on a sample basis against the advertising spend data compiled by Nielsen Media Research, TAMIndia and NDT Japan.
