New matrices are created each month-end. Ex-ante tracking error and risk estimates are determined by applying the calculated sensitivities to the covariance matrix. © IDS GmbH – Analysis and Reporting Services 20 21 Cross Sectional Regression Process First regression measures Treasury yield curve shifts by regressing local currency returns in excess of yield and convexity effects on D1, D2, and D3 on Treasury bonds for each currency in model: Second regression measures spread changes by sector and quality buckets by regressing return in excess of yield, convexity, and D1, D2, and D3 on spread durations and elasticities for non-Treasury bonds for each currency in model: © IDS GmbH – Analysis and Reporting Services 21 22 Specific Risk The specific risk factor coefficients are obtained through a two-step estimation using the factor return residuals. The basic assumptions about the factor return residuals specific risk from the regression are: • The residuals follow a normal distribution. • The residuals have no correlation with the factor returns. • The estimated risk is proportional to the spread duration. Step I : Sector coefficients calibrated with Aaa rated securities. Step II : Quality coefficients calibrated with non-Aaa rated securities. © IDS GmbH – Analysis and Reporting Services 22 23 Specific Risk Illustration: Quality Coefficient © IDS GmbH – Analysis and Reporting Services 23 24 Risk Report produced by: IDS GmbH 17/04/2012 Ludek Kolecek ++49 89 3800 15139 Risk Report 30/03/2012 Fund 1 Benchmark 1 Portfolio Benchmark Portfolio Description 84 SIMCORP:DIM Base currency: EUR Asset type No. of Market investm Value ents Portfolio Benchmark Portfolio Database: 208 3,026 Eff Dur Spr Dur Avg Cpon Avg Life Yield to Mat Rating Avg % n.r.
