The scope of the work is limited to Australian employee benefit schemes, and excludes any schemes of foreign subsidiaries of domestic entities which are denominated in foreign currency. This report provides the Australian corporate bond discount rate curve as at the end of May 2015 produced under the methodology and assumptions described in the ‘Discount Rates for Australian Employee Benefit Liability Valuation’ report. Reliance and limitations In producing this report, we have relied upon the following information: Capital market data as sourced from Bloomberg. Should this data be incorrect, it could materially affect the analysis and conclusions drawn from it. Users of this report should also be aware that it is subject to the following limitations: Current debt market conditions. Issuance of corporate bonds is subject to change over time, which may impact upon whether the accounting standard requirements of a deep market are met. Current capital market conditions, in particular the liquidity and credit ratings of corporate bond markets, which can change rapidly. The asset calibration set could change very rapidly under stressed market conditions. Reassessments of the suitability of the asset calibration set would be needed if the AAA and/or AA corporate bond market thins, which would require a prospective change to the assets selected for AASB 119 calibration purposes. This report was prepared solely to provide assistance to the Group of 100 and the relevant Actuaries Institute of Australia subcommittee. Milliman does not intend to benefit and assumes no duty or liability to other parties who receive this report. Milliman recommends that any recipient of this report be aided by its own actuary or other qualified professional when reviewing the report. Milliman does not certify the information in this report, nor does it guarantee the accuracy, completeness, efficacy, or timeliness of such information. Use of such information is voluntary and should not be relied upon unless an independent review of its accuracy, completeness, efficacy, and timeliness has been performed. Materials may not be reproduced without the express consent of Milliman. May 2015 1 Milliman Report Group of 100 Discount Rate 2 METHODOLOGY AND ASSUMPTIONS Summary of the asset calibration set The set of assets to be used to calibrate the discount rate curve is defined by those securities that meet the following conditions: 1. Individual bonds must have the following characteristics: a. Physical bonds, with no embedded derivatives (e.g., callable, putable, convertible, extendible, variable/floating coupon, index-linked) b. High-quality corporate bonds issued by both domestic and foreign entities c. Payments denominated in Australian dollars (AUD) d. Pay fixed (or zero) coupons, non-inflation-linked e. Maturity terms of greater than one month and less than 10 years f. Minimum amount outstanding on an individual security of $100 million g. Securitised bonds are included 2. A deep market for these bonds must exist, as characterised by the ready availability of observable prices and current trades. What is meant by high quality? Figure 1 defines the credit ratings by each agency that map to each of these broad categories. This forms the basis for the asset calibration set used in this report. Figure 1: Definition of AAA and AA Credit Ratings by Agency Category S&P Fitch Moody’s AAA AAA AAA Aaa AA AA+, AA, AAAA+, AA, AAAa1, Aa2, Aa3 Where there is disagreement between credit rating agencies on particular securities, we use the following conditions: If a security has at least two AAA ratings, then it is classified as a AAA security If a security has at least two AA ratings, then it is classified as a AA security If a security has only been rated by two agencies with different ratings, then the lower rating is used If a security has only been rated by one agency, then that rating becomes the sole reference Hereafter, all references to credit ratings refer to those that meet the above conditions. For the purposes of this paper, we refer to this as the combined credit rating. May 2015 2 Milliman Report Group of 100 Discount Rate Corporate bond universe The table in Figure 2 shows the decomposition of the market by the combined credit rating satisfying all but the ‘high quality’ characteristic.

May 2015 3 Milliman Report Group of 100 Discount Rate Interpolation methodology For fitting the discount curve to the asset calibration set, the Merrill Lynch Exponential Spline (MLES) method with nine exponential basis functions was used calibrated to yield data as at 29 May 2015, weighting each issue by the inverse duration of the issue. The results of the calibrated MLES parameters are shown in Figure 4. Figure 4: MLES-Calibrated Parameters as at 29 May 2015 MLES Parameters Long-Run b0 5.7% Param1 λ1 125.2% Param2 λ2 14.5% Param3 λ3 -71.1% Param4 λ4 36.4% Param5 λ5 39.3% Param6 λ6 -3.0% Param7 λ7 -66.7% Param8 λ8 -15.2% Param9 λ9 40.7% For the calibration of the MLES basis functions, an adjusted R-squared statistical goodness-of-fit measure was applied to the difference between modelled and actual bond prices. An adjusted R-squared statistic value close to 100% indicates a very good fit, whilst lower values (closer to 0%) indicate poor fits. Figure 5 shows the results of the interpolation analysis used. Figure 5: Adjusted R-Squared Statistic as at 29 May 2015 Regression Statistic Adjusted R-Squared 90.6% Extrapolation methodology For rates beyond 10-year maturities, the fitted yield curve has been extrapolated by assuming that 1-year forward rates remain constant for all subsequent maturities. This is based on the 1-year forward rate between 9- and 10year maturities, based on the fitted MLES model. May 2015 4 Milliman Report Group of 100 Discount Rate 3 FITTED YIELD CURVE Figure 6 shows the modelled yield-to-maturity for each bond in the asset calibration set, compared with the actual yield-to-maturity, using the MLES method with inverse duration weightings. Note that these are the same bonds as those discussed and analysed in Section 2 above. Figure 6: Modelled vs. Market Yields to Maturity for Asset Calibration Set Using the MLES Method with Inverse Duration Weightings May 2015 5 Milliman Report Group of 100 Discount Rate Figures 7 and 8 show the resulting spot and forward yield curves of one to 50 years for the calibration set using the MLES method and extrapolated with the constant forward rate extrapolation method. Spot rates shown are quoted as annually compounded rates on zero coupon bonds with maturities of the specified term, forward rates shown are 1-year forward rates ending at the specified term.
