NEW YORK (S&P Global Ratings) Aug. 10, 2017--S&P Global Ratings said today that its ratings on BWAY Holding Co. (B-/Stable/--) are unaffected by the company's proposal for a $150 million add-on to its existing 7.25% senior unsecured notes due 2025. We expect that the company will use the proceeds from this add-on to redeem all of its preferred equity.
