The yield on the junk bonds jumped above 89 per cent following the downgrade, and was recently near 87 per cent, having been near 16 per cent before UCI last reported earnings in October. A soaring bond yield means the value of the debt has slumped and typically suggests that bond investors see less chance of getting interest payments or their money back.
UCI has yet to file its fourth-quarter and annual 2015 accounts with the US Securities and Exchange Commission since reporting a 68 per cent slump in third-quarter adjusted earnings before interest, tax, depreciation and amortisation to US$6.3 million.
Hart put UCI in strategic review in 2014 and amended the company's credit agreements to enable asset sales, before selling its Wells vehicle electronics business for US$251 million.
The auto parts firm refinanced US$75 million of bank debt with a new credit line with Credit Suisse in September last year, which left it with debt of US$477.1 million as at September 30, and a month later it repaid US$12 million of that facility. The bonds were sold during Hart's 2011 leveraged buyouts of UCI for US$980 million and a separate auto parts firm, FRAM Group, for US$950 million. Holders of the debt include BlackRock, JP Morgan, Credit Suisse and Pimco.
Hart started building the business when he was creating a much larger packaging empire, Reynolds Group Holdings, using junk bonds to fund both expansions when near-zero interest rates around the world left investors clamouring for real returns.
