See Credit Default Swaps on Steroids: UBS's Willow Fund and Willow Fund's Hedging, Investing and Speculating in Distressed Debt With Credit Default Swaps. Through these CDS contracts, the Willow Fund made a large, highly-leveraged short bet on credit risk contrary to its repeated SEC...

Our Champion Income Fund paper is available on our website. Oppenheimer had increased Champion Income Fund's exposure to CMBS through credit default swaps and total return swaps in 2007 and 2008.

Valuing products with exotic derivatives can be difficult since these products typically have complex payoff formulas. One of the most flexible methods for valuing such products is called Monte Carlo simulation. At SLCG, we use Monte Carlo simulation in a lot of our work, so we thought it would be helpful to explain a bit about it and show how it can be used to estimate the future returns of an asset.
The basic idea behind Monte Carlo simulation is to determine the statistical properties...
