—with regard to a number of large contracts that we currently have, including, for example, the building maintenance contracts that we have with SNC-Lavalin, the company has voluntarily added to its existing contracts with us the terms of the integrity provisions that we have.
We have been working with a number of companies with which we have significant contracts or that span a long term to see if they would voluntarily adopt the integrity provisions. They're not compelled to do so, because obviously the contracts were signed before the integrity provisions were put in place in some instances. For any new contracts that we have with the company or any other company, as I mentioned earlier, we do the systematic review and check on a contract-by-contract basis.
