Orange County yesterday agreed to pay $1.769 million for an interest  rate cap that will protect the county against a significant rise in   interest rates between now and the planned sale of $720 million of recovery   bonds at the end of June.     
In a deal described by several market observers as the first of its  kind, the county chose Goldman, Sachs & Co. to supply the cap - effectively   an insurance policy - in competitive bidding.   
  
The contract will protect against any increase in municipal bond yields  of more than 75 basis points between pricing yesterday and June 30. 
In what derivatives market players said was an unusual structure - some  called it unprecedented - the cap was broken down into 30 individual   portions, giving Orange County protection for each of the serial maturities   it plans to sell.     
  
Caps have generally been against a single index, derivatives market  sources said. But they added that such an arrangement does not protect   against changes in the shape of the yield curve that could lead to the   county having to pay higher interest rates if the curve, for example,   flattens without changing in overall level.       
The county entered into the derivative contract in connection with its  sale of $720 million of recovery certificates of participation, scheduled   to come to market before June 30 as part of the bankruptcy recovery plan.   
"It is very unique," said Christopher Varelas, principal at Salomon  Brothers Inc., which is serving as financial adviser to Orange County. "We   wanted to structure a cap that protected the county from various types of   interest rate exposure, both an increase in rates and also a rotational   shift or flattening of the yield curve."       
To achieve this, the cap is linked to the levels of the Municipal  Market Data's triple-A insured yield curve. If the yield at each maturity   on June 30 is more than the strike price of 75 basis points above the yield   at pricing yesterday, Goldman will have to pay out the excess interest cost   on that maturity.       
Explaining why the county bought the cap, Varelas added: "Purchasing  the cap eliminates the one variable beyond the county's control and ensures   that the county's available revenues will be sufficient to pay off the   obligations needed to emerge from bankruptcy."     
Four firms bid on the deal, having qualified after going through a  selection process. In addition to Goldman, they were: Bank of America,   Lehman Brothers, and J.P. Morgan Securities Inc.   
Asked to suggest how the deal should be executed, Andrew Garvey -  senior vice president and marketing manager in Lehman's municipal swaps and   investment products group - said his firm had suggested the 30-part cap   structure on Monday because it more closely matches the bonds Orange County   will issue.       
"The key is, it's a more precisely tailored hedge to make sure they  were protected from all interest rate movements," he explained. 
His colleague, senior vice president Rob Taylor, added that the large  number of Municipal Market Data scales available made it possible to choose   the one which best matched the expected pricing of the bonds across the   entire yield curve. In addition, he said, the MMD scales are one of the   most accurate.       
Another derivatives market player, who asked not to be named, said it  was the first structure of this kind he had seen. 
However, he said the use of caps to protect against interest rate  movements in this way is a growing market, even though it is more common to   use a single figure for pricing such as the PSA index or the London   Interbank Offered Rate.     
Bidders on the deal, he added, needed a lot of technical skills because  of the deal's complexity, the "outsize" $720 million notional amount, and   $600,000 cost of a one basis point change if the strike price is exceeded.   
Tom Nichols, general manager of Municipal Market Data, a sister company  to The American Banker-Bond Buyer, said the adoption of MMD's index was   confirmation of its accuracy as a benchmark.   
Goldman declined to comment on the deal.
