Junk Bonds are Overvalued, Defaults to Rise, NYU's Altman Says

Junk Bonds are Overvalued, Defaults to Rise, NYU's Altman Says

High-yield, high-risk bonds are overvalued and may tumble as default rates in the U.S. more than triple this year, said Edward Altman, a New York University professor who in the 1960s created a widely used mathematical formula that measures the risk of bankruptcy.

Altman predicts 2.50 percent of the $1.1 trillion junk bond market will default this year, up from 0.76 percent at the end of 2006. The rate will climb to 2.72 percent in 2008, he said last night at a Fixed-Income Analysts Society Inc. event in New York.

With companies having little trouble meeting interest payments, investors have pushed yield premiums on speculative- grade bonds to the lowest in a decade. Junk bonds yield 2.63 percentage points more than Treasuries on average, down from 3.54 percentage points a year ago, according to data compiled by Merrill Lynch & Co..

Even with a ``modest spike'' in defaults, ``it's hard to see how this market is going to do well,'' Altman, 65, said. Some investors predict default rates will remain below 1 percent this year and ``they have to say that'' to justify why they are buying bonds at such narrow yield spreads, he said.

Junk bonds are rated below Baa3 at Moody's Investors Service and below BBB- at Standard & Poor's. The securities returned 11.8 percent last year, including reinvested interest, their second- best performance since 1997, Merrill Lynch index data show. Bonds rated CCC and lower did the best, gaining 18.6 percent.

Z-Score

Altman in 1968 created the Z-score, a mathematical formula that measures a company's bankruptcy risk. Ratios such as working capital, or the amount of money available to run a business, to total assets are used in determining the Z-score. The lower the score, the higher the risk of bankruptcy.

Money from hedge funds and private equity firms are giving the riskiest borrowers access to capital and keeping default rates low, said Altman, who predicted in January 2005 the rate would rise to 4.27 percent last year from 3.37 percent.

``Just about everybody who forecast defaults was wrong,'' said Altman. ``I don't know if I am eating humble pie.''

Cheap debt has helped fuel a record amount of leveraged buyouts, where takeover firms use a combination of their own funds and debt issued in the target's name to fund the acquisition. Private equity firms and management announced more than $700 billion of takeovers last year, a record.

``We're able to borrow at unusually low spreads,'' Steven Rattner, co-founder of buyout firm Quadrangle Group LLC, said in an interview at the World Economic Forum in Davos, Switzerland. ``I'm not sure I'd want to be the buyers of that high-yield paper. The world isn't pricing risk appropriately.''

Record Sales

Companies sold a record $184 billion of junk bonds last year, and loans with below-investment-grade ratings reached an all-time high of $682 billion, according to data compiled by Bloomberg.

``There's an incredible amount of liquidity, primarily coming from non-bank institutions,'' Altman said. He estimated hedge funds account for as much as 40 percent of all trading in high-yield bonds.

Sales of the riskiest junk bonds, those rated CCC, may spur defaults, Altman said. Junk bonds that were rated B- or lower when they were issued accounted for 42 percent of high-yield sales last year, according to S&P.

Open Solutions Inc., a provider of software for financial- services companies, last week sold $325 million of 9.75 percent eight-year notes to finance its $1.4 billion takeover by the Carlyle Group and Providence Equity Partners Inc. The debt is rated Caa1 by Moody's and CCC+ by S&P.

`Very Disturbing'

``These chickadees are going to come home to roost,'' Altman said. ``But they're very happy eating in their barnyard, and they haven't. Which is very disturbing.''

The percentage of bonds considered in distress fell to a record low of 1.3 percent this month from 1.6 percent in December, S&P said this week in a report. Seventy companies had bonds trading at distressed levels, down from 97 in December, according to S&P, which defines distressed bonds as those with yields more than 10 percentage points above Treasuries.

Merrill Lynch's index of distressed bonds has shrunk to a face value of $6.5 billion from $27.4 billion at the end of 2005 and $161 billion in 2002.

``Every time there is a big bankruptcy we do open a bottle of fine wine in my household,'' said Altman. ``It's been a real dry spell. I am hoping for a more liquid situation going forward.''
