Testing Hedge Effectiveness for FAS 133: The Volatility Reduction Measure
Journal of Applied Corporate Finance (Winter 2001)
The VRM, a ratio-based statistic invented and patented by Andrew Kalotay Associates, fulfills the spirit of FASB’s recommendations for hedge effectiveness testing, while correcting their major shortfalls. It can be used for both prospective and retrospective testing.

Derivatives Strategy (March 2001)
An Andrew Kalotay Associates innovation, the VRM pinpoints the degree to which a hedge offsets the volatility of a particular asset, liability or portfolio.

The Challenge of Managing Credit Spreads: New Tools on the Horizon
Journal of Applied Corporate Finance (Fall 1999)

Ratchet Bonds: Maximum Refunding Efficiency at Minimum Transaction Cost
Journal of Applied Corporate Finance (Spring 1999)

BondWeek (July 13 1998)
The Tennessee Valley Authority’s putable automatic rate-reset securities (PARRS) issued in 1998 were the first-ever ratchet bonds – a revolutionary structure that captures virtually all the advantages of conventional bonds for both borrowers and investors, while eliminating the disadvantages. Andrew Kalotay first proposed the ratchet bond concept to TVA and worked with the agency to structure the PARRS security.
