The policies have been consistent for some period of time. The core question is the application of a different threshold.
As I indicated in my opening remarks, we undertook a thorough review and did reach the conclusion that at this point spend remains the best and most reliable indicator of factors such as reach. These are factors that were identified by the Auditor General, and it's potentially important.
Simply, that spend level is a reliable indicator of the potential impact and risks associated with the advertising campaign, but the policy and criteria have been consistent over a period of years.
