Do I need I-864a?

[red74]

I am sponsoring my father. My income is not much on my tax returns so I am showing assets in the form of a mutual fund with many times more than is required. My question is this - do I need to include an I-864a simply because my wife and I file joint tax returns and so her name will be on the return? Or since I am showing assets way above what is needed in a mutual fund that is in my name only is it not necessary? Thanks for any help.

If you are not counting your wife's income or assets, she does not need to fill out an I-864A.
