What we do when we are budgeting for an audit is we essentially budget for the audit to unroll without there being any issues. For example, we say this is the number of hours we expect we should be able to complete this audit in if we don't identify there being any issues within that audit. The 15% is giving us a 15% cushion across our whole portfolio of audits, in that we recognize there are going to be instances when there are issues in an audit that need to be worked through.
We don't go in assuming that every audit is going to have those types of issues and therefore provide a higher budget to deal with it. We go in assuming there are no issues—the lower amount of budget—but then we give ourselves some room to say we've still got a 15% cushion to deal with any issues that might arise.
