English to French Bus/Financial Accounting Public Finance Management

Context:

"Off-budget expenditure and on-budget transfers have increased over the years to the detriment of on-budget programs in health education"

I understand the meaning, but feel unsure about a good translation.

Off-budget is hors budget of course, but on-budget (dans le respect du budget, ou dans les limites du budget), but am looking for a more concise and precise way of translating this term.

Your expert advice would be much appreciated
