Credit value at risk (VaR) is used for measuring and analyzing credit risk of a portfolio. The basic methodology of the Credit VaR employs the credit migration approach spearheaded by RiskMetrics. It assumes that obligor’s credit quality is determined by the obligor’s asset value, which in turn is approximated by its standardized equity return.

The aesthetics of early feature-film scores were shaped by narrational problems introduced by multi-reel features and their longer durations. Using The Patchwork Girl of Oz, I show how stylistic devices like silences and musical pun- ctuation were used to address the coherence and pacing of multi-reel storytelling.

We present a model for pricing a credit derivative product where party A has sold default put protection on a Euro denominated bond. Specifically, upon bond issuer default, party A must pay to party B a notional amount of 10 million USD (excluding accrued interest). In exchange, party B must pay a fixed rate to party A, on a quarterly basis,…[Read more]

We present a valuation model for pricing a gold derivatives trade. The trade can be structured to synthesize a typical gold-miner’s hedge, specifically, a swap in which one party receives long-term interest rates and pays a blend of short-term interest rates and short-term gold lease rates.

We present a model for pricing a path-dependent, equity-linked payoff. Here a bounded price return is calculated from an underlying index at certain pre-specified dates. The total return at maturity is given by the sum of the bounded price returns above, but where a specified number of the highest of these returns are set to a cap value.

A model is presented for pricing an American call option on stock. The option tenor is n years, and its strike price is increased every anniversary. It has also the following feature: if the stock price stays in excess of 200% of the current strike price during 10 consecutive trading days. The seller can issue a notice to the buyer that one half…[Read more]

We present a valuation model for pricing two asset barrier options on commodity futures. Applications to commodity futures have a number of specific. The analytical valuation formulas are also implemented. The payoff of a two asset barrier options is made against one of the assets, while the other asset is used to trigger the barrier.

A two-asset barrier option is a European style option whose value is determined by two underlying assets. One asset, S1, determines the payoff function, and the other, S2, knocks the option in or out if the S2 value crosses the barrier.
