Investment Grade credit rating requirements + margin rebound

[AA3]

Подскажите пож-ста варианты перевода для выражений в саб-же.

We believe these improvements will lead to a rapid pay down of debt, and should allow HEI to meet Investment Grade credit rating requirements. Our EBITDA estimates are XX% ahead of Reuters consensus through 2010-11E on average and we believe the market is not fully factoring in the extent of XXX’s cost cuts, as well as any possible margin rebound.

Заранее спасибо!
