International credit rating agency Moody's said Tuesday that the U.S. government's tax proposals would benefit all but highly leveraged companies.

It said that the U.S. government's proposed corporate tax overhaul would benefit all U.S. non-financial companies except those with high debt loads.

Moody's also commented on U.S. tax proposals, suggesting that interest deductibility limits would dampen attractiveness of private equity buyout model.

The international credit rating agency also said that plans to impose earnings-based limits on interest deductibility are credit negative for most companies.
