The Gaussian copula model is initially applied to calculate joint default probabilities among the reference entities, then these probabilities are used to determine the expected cash flows from the CDO tranches which, in turn, are discounted back to present value based on the spread payments approach.

First, the spread payments approach calculates individual entity's default intensities, and then the Gaussian copula model synthesizes these into a multidimensional distribution to estimate the likelihood of simultaneous defaults; this information is used to price the CDO tranches.

In this method, the spread payments approach initially estimates the fair spreads for each tranche based on historical data. Subsequently, the Gaussian copula model predicts the time to default for each referenced entity, and these predictions are used to adjust the estimated cash flows.

The valuation process starts by utilizing the spread payments approach to establish an overall risk premium for the CDO. Then, the Gaussian copula model simulates correlated defaults across the portfolio to reallocate this premium among the different tranches according to their specific credit risks.
