This indicates that the Financial Toolbox will not work properly (or possibly not at all) without the other toolboxes. This means you will have to purchase those as well. They are not included in the price of the the Financial Toolbox.
Note: I'm not a Mathworks employee, so you should take my word for what it is: the advice from a stranger on the internet. However, this is how it worked for me. If you want to make sure, you can always contact Mathworks support directly (you can find the button at the bottom of the page), or wait for an employee to notice this thread and to confirm or contradict my explanation.
