There is oversight on the contracts that we provide in PWGSC, but taking into account the objective of this appearance, I assume you're referring to the contracts awarded by SNC-Lavalin O&M.
As I mentioned in my opening remarks, there have been reviews of this contract in four successive years, plus we provide a function centrally and a national office to oversee the monthly payment of invoices and the scrutiny of the work orders and the projects performed. We assess the work delivered versus the estimates provided before the work is authorized.
