My company would be really hampered if Equifax went bust. We do use two other credit bureaus, but some functions depend on data only Equifax provides.

We also use the different bureaus together for cross checking, often one bureaus file will be out of date or have errors, while the other is fine. So we'd have a much harder job of calculating risk if one of the big bureaus went out of business, simply because we'd be losing a major data source that drives our business.

I am very sure this case applies to other financial institutions as well.
