PPM Sample Guarantee Pierre Bouvard President Sales and Marketing

Sample Guarantee: Background In the summer the total panel sizes in Philly and Houston were short of target We took steps to address the shortfalls and those steps have paid off... both markets are back over target We stand behind the quality of the estimates

Why the Guarantee Meeting sample targets is paramount for instilling confidence in the currency and we will hold ourselves more accountable for doing so The guarantee puts Arbitron's "skin in the game" If we meet our targets there will be no need for rebates

What We Will Guarantee The average daily in-tab for each market among persons 6+ for a given survey month will equal or exceed 90% of the sample target for that market Average daily In-Tab for Persons 6+ anchors the statistical efficiency of the overall sample A 10% "guardrail" for Persons 6+ is an appropriate and important first step Rebate one percent of the net monthly rate for each point we are below the threshold for a given market

The Guarantee When and How Philadelphia and Houston Goes into effect with the October survey New York and all subsequent markets Effective first month of currency Threshold starts at 85% for the first currency month and builds by one percentage point per month to 90%

Narrowing the Guardrails The Advisory Council recommended an additional step to narrow the guardrail to Persons 18-54 We agree that 18-54 is an appropriate next step Initiatives are in place to address 18-24 and 25-34 which are the keystones to performance for 18-54 We expect to begin seeing the results of that work in the second quarter of 2008 Assuming positive results of our young adult initiatives we will provide a date and plan to implement the 18-54 guardrail at July council meeting
