How to perform the Asset Liability modelling to decide the investment strategy.
Actuary elbow grease to projection company’s assets too liabilities into hereafter too and hence banking enterprise check whether insurance fellowship has sufficient assets to come across at that spot liabilities or not. Along alongside that Actuary also checks whether the solvency seat equally required yesteryear regulator is satisfactory or not.
Asset liability modelling is a tool to projection assets proceeds too liability outgo into the hereafter that tin last used to help inward setting investment strategy to command the jeopardy of falling to come across an objective.
Now enquiry inward your heed would last what is objective?
For ex: Objective tin last that assets should last to a greater extent than than liabilities for the adjacent 10 years alongside 99.5% confidence interval. In Objective, nosotros elbow grease to arrive quantifiable along alongside fourth dimension horizon too a defined probability interval.
Now to projection assets nosotros cause got to watch diverse types of asset classes such as:
· Money marketplace instruments (for that nosotros remove curt term involvement rates)
· Bonds (for that nosotros remove inflation, gross redemption yield)
· Equities (we remove dividend yield too expected hereafter growth)
· Property (we remove rental yield too expected rental growth)
· Overseas assets (we remove hereafter telephone commutation charge per unit of measurement movements too yields inward those countries)
First of all, bifurcate all the existing assets inward major asset classes (govt. bonds, corporate bonds, equity too belongings etc) too assign expected hereafter returns from each asset class. In illustration of bonds, nosotros volition also consider proceeds at maturity
While projecting asset values, nosotros remove to brand next assumptions:
· Future involvement rates
· Future inflation
· Future existent yields
· Rental yields too hereafter Rental growth rates (for property)
· Dividend yields too hereafter dividend growth rates (for equities)
The projection of assets includes both income (coupon/dividend/rent) too maturity proceeds, if any
· Liability hither agency Net liability i.e. Benefit payments to policyholders + Expenses too commissions incurred inward servicing the contracts + Other insurance related liabilities – Premiums received.
· Outgoes tin last
o Fixed such equally Fixed amount assured inward illustration of term insurance
o Variable i.e. index linked
o discretionary for example, bonuses on with-profit policy
· Expenses are unremarkably linked to toll inflation or salary inflation. Estimate the expected expenses for the portfolio.
· The term (i.e. duration) of outgoes depends on probable timing of the payments.
· Choose appropriate model points (i.e. Model betoken is a ready of information representing a unmarried policy or a grouping of policies. It captures the some of import characteristics of policies that it represents.) which reflects underlying portfolio.
· Need to brand assumptions based on liability. For ex, if production is annuity too hence grade of longevity, grade of annuity increase, taxes etc.
· we tin too hence guess the expected outgoes inward each year.
· The ALM model tin last deterministic or stochastic depending on the role of modelling.
Determine the Investment Strategy
· The Actuary’s initial betoken for the model would last to specify the objective. For ex, to decide an asset allotment / investment strategy such that the probability of the solvency grade falling below x% over the adjacent y years is less than z%. (i.e. Solvency ratio falling below 150% over the adjacent 10 years is less than 0.5%)
· Given the recent regulatory requirements, the solvency grade mightiness last defined yesteryear a regulator (such equally inward illustration of Solvency II), although an in-house valuation Earth could also last used (such equally inward illustration of ECap i.e. economical capital)
· The model would projection the cashflows associated alongside the asset proceeds too liability outgo
· A determination would cause got been needed equally to which variables to model stochastically too which to model deterministically. For example,
o Stochastic modelling for:
§ investment returns
o Deterministic modelling for:
§ Withdrawal rates
· Model should demo articulation human relationship betwixt variables. For ex,
o Withdrawal charge per unit of measurement may last correlated alongside economical weather i.e. inward illustration of economical downturn, withdrawal rates volition increase
o inflation rates too investment returns, bonus rates too investment returns
· For the stochastically modelled variables, probability distributions volition cause got been determined along alongside parameter values for ex, hateful investment returns / inflation rates, variances too correlations betwixt variables volition last considered. Similarly parameter values for deterministic modelled variables volition last assumed.
· The actuary would cause got chosen a lawsuit asset allotment too carried out a large release of simulations (say 1,00,000) based on unlike values generated from the random variables
· The results of the model volition cause got been compared alongside the objective
· The Actuary volition likely cause got tried many unlike asset allocations, leading to a arrive at of potential asset allotment strategies that come across the objectives.
· Sensitivity too scenario testing volition cause got too hence been carried out on these strategies (sensitivity testing agency checking the send upon on output yesteryear changing 1 supposition or variable at a time. Scenario testing agency yesteryear changing to a greater extent than than 1 variables at a time)
· This volition cause got led to a reduced release of acceptable strategies to last presented to the management. For illustration strategy would be
o 50% inward Government bonds
o 25% inward Domestic equities
o 25% inward Corporate bonds
