Liability-Driven Investments (LDI) model Executive Summary • Liability-Driven Investments (LDI) as well as Asset and Liability Management refer to those situations in which investors must manage together their assets and their liabilities. Since it is unlikely that an investor has no liabilities at all, most real-world investment situations can be categorized as Liability-Driven Investment • Unlike Asset Allocation, which offers quite a well-established framework, LDI and ALM cannot refer to any well-identified theoretical body • As such, most financial institutions are forced to make their own way through the interactions between asset allocation and liability hedging within an ever-changing accounting and prudential environment • • Eurizon has been set up an intertemporal model for the asset allocation based on an LDI perspective • For the estimation of the traditional inputs that govern an allocation – expected returns and volatilities –Black&Litterman model (Expected Returns or the reverse engineering) and the Variance/Covariance Matrix have been respectively used • Based on these arguments, we design an objective function that returns the vector of weights maximizing the probability that, at a given maturity, the value of the assets is above the liability’s level • • The function depends also on past performances and on time to maturity • The model is further detailed in the following slides by focusing on three main aspects: Starting from the dynamics followed by assets and liabilities, and thinking in relative terms (asset over liability and not assets per se) we derived the dynamics of the funding ratio In order to regulate the optimization we add several constraints: no short selling, risk budgeting, an ex-ante variable (life Cycle) volatility constraint and ex-ante stop loss mechanism o 1 Objective Function o 2 Optimization Constrains o 3 Glide Path Constraints
1 Objective Function Protection break Success probability Where: Ft = Assett/Liability 1 t Risk adversion coefficient FT = Assett/Liability 1 t Pt = Assett/Liability 2 K 1 Ft , K 1 Pt , K 1 FT = Objectives A multi-objective function considering as optimal allocation the one that maximizes the probability of reaching several objectives within a predefined time horizon minus the probability of negative perfomances
2 Optimization Constraints Maximization is subject to a certain number of constraints • • For TEV we mean Tracking Error Volatility and is computed against the Liability: The third constraint impose a maximum percentage of risk contribution for each asset
3 Glide Path Constraints Risk Constraints Maximum Volatility Minimum Volatility Risk Budgeting • • • According to risk limit Decreasing according to the maturity and Glide Path Defined in order to preserve portfolio’s value proposition • These limits are set up for controlling risk budget allocation • They can be absolute or relative • They can be related to single stock, asset class or groups Allocation Constraints Upper and Lower bounds for each investment • • Weights’ cap by group type Leverage limits Duration Bounds introduce limit to long/short positions Objectives K 1 Ft Allowing to define investment limits for markets, sectors and geographical area • Both absolute and relative • Allowing to set up lower ed upper bounds according to each asset class duration (or even at group level) K 1 Pt K 2 Alpha • Funding Ratio objective (first target date) • Funding Ratio objective (second target date) • Second objective linked to first target date • Level of protection for the Funding Ratio • Coefficient of risk adversion
