Moody’s Seen Playing Catch-Up in Plan to Change CoCo Ratings

May 6 (Bloomberg) -- Moody’s Investors Service is seeking to grade a wider range of bank capital securities to catch up with competitors rating bonds designed to absorb losses in a crisis.

Moody’s is asking investors to comment on a proposed framework for grading high-trigger contingent capital bonds, the second time it has sought to revise the way it rates CoCos. The New York-based company changed its methodology last year to allow it to rate certain types of CoCos after saying in 2010 it probably wouldn’t rate the securities at all.

CoCos, which are designed to impose losses on holders rather than taxpayers, convert to equity or are written off if the issuing bank’s capital falls below a preset amount. European regulators last year agreed the terms on how the most-junior Tier 1 securities should be structured, prompting issuance in that market to soar to more than $30 billion, with Moody’s rating about one-sixth of that volume, according to data compiled by Bloomberg.

“Moody’s are playing catch-up, they’re behind the curve on this,” said Mark Holman, chief executive officer of TwentyFour Asset Management LLP in London, which oversees about $3.9 billion of fixed-income assets. “Not rating these is costing them money.”

CoCo bonds typically take losses when capital as a percentage of risk-weighted assets falls to 5.125 percent or 7 percent for high-trigger notes. Additional Tier 1 bonds, the fastest-growing and riskiest segment of the market, can also suspend coupon payments if capital buffers are breached before triggers are reached.

“We had a moratorium on rating high-trigger CoCos because of the difficulty of predicting when an impairment would be triggered through conversion to equity or writedown and the lack of consistency in the deal structures,” said Mark LaMonte, chief credit officer for financial institutions at Moody’s in New York. “These uncertainties and inconsistencies have significantly reduced over the last year or two.”
