In the grand scheme of the entire portfolio of student financial assistance, I would just like to point out as a point of clarification that the overall operating cost of the Canada student loan program in 2017-18 was $2 billion.
The program itself includes a number of components, as you know. There is the repayable portion, which is the actual Canada student loan. There's also the non-repayable portion, which refers to our Canada student grants and our repayment assistance plan. The balance of that $2 billion reflects the full cost of all of those components of the program.
As a point of clarification on a point made earlier, I believe that the $700 million that was referred to, in terms of coming in through our interest rate charges, reflects the interest rate investments coming in, but it also helps to defray the costs of the non-repayable portion of the Canada student loan program, which includes the Canada student grants and the repayment assistance program features as well.
In regard to the default payment, the writeoff for 2018-19 was just over $160 million, approximately. In the grand scheme of this portfolio, it is quite small.
