You are reading it correctly. What I'd like to point out is that the main estimates are an initial proposal to Parliament. Last year, for example, between the main estimates and the additional supplementary estimates (A), (B), and (C), CIDA received from Parliament an additional $500 million. So if one looks at main estimates this year compared to main estimates last year, there is actually an increase. And last year's main estimates were larger than the year before.
