16. Asset-liability management Flashcards

1
Q

What are the two key principles of investment?

A
  • A provider must select investments that are appropriate to the nature, term, currency, and uncertainty of liabilities and the provider’s appetite for risk
  • Subject to the above – Investments should maximize overall return (both income and capital gain)

Q

What are the cashflows on a single life immediate annuity from the perspective of the provider?

A
  1. Single premium → positive initial lump sum
  2. Annuity payments → regular series of negative cashflows
    * Timing → known
    * Amount → monetary or real terms
    * Term → unknown – lifetime of insured
  3. Investment → initial negative cashflows – investment of premium
    * Series of positive cashflows = interest + capital payments
  4. Expenses:
    * Initial lump sum negative cashflow → commission + setup expenses
    * Regular negative payments → admin of benefit payments
  5. Expected to increase over time in line with wages/price inflation

Q

What are the cashflows of a term assurance from the perspective of the provider?

A
  1. Premiums → regular series of positive cashflows
    * Timing is usually known in advance
    * Amount is usually fixed
    * Total term is unknown
    * A variation is a single premium contract
  2. Benefit → a lump sum negative cashflow
    * Paid on death of the policyholder
    * Timing is unknown
    * Amount of sum assured is known
    * If survives term → no benefit cashflow
  3. Investment
    * A series of positive cashflows of interest and capital
    * Negative cashflow when investments are purchased
  4. Expenses
    * Initial lump sum negative cashflow to cover commission and setup expense
    * Regular negative cashflows → admin expense
    * Termination lump sum → negative cashflow payable on death → claims handling

Q

How do the cashflows from the perspective of the provider on a without-profit endowment assurance differ from those on a TA?

A
  • Additional negative lump sum cashflow on maturity
    1. If the policyholder survives until the end of the term
    2. Amount will be known
  • May be a lump sum negative cashflow if the policyholder surrenders
    1. Amount may or may not be known – depends on contract
  • For a given sum assured → the premiums will be greater
  • Investment income and gains would also be greater

Q

What are the cashflows of a repayment loan from the perspective of the provider?

A
  1. Loan amount → initial negative cashflow equal to the amount of the loan
  2. Interest and capital repayments → regular series of positive cashflows
    * Each payment = interest + capital
    * Capital component increases over the term
    * Interest component decreases over the term of the loan
    * Total amount may be fixed or variable
    * Or specified to increase or decrease
    * Timing and total term is usually known in advance unless it is paid early or a party defaults
  3. Expenses
    * Initial lump sum negative cashflow to cover commissions and setup expense
    * Regular stream of negative cashflows → admin + collecting payments expected to increase in line with price or wage inflation

Q

How are the cashflows on an interest-only loan different from those of a repayment loan?

A
  1. Interest-only → regular repayments only comprise interest
  2. Interest may be fixed or variable
  3. Additional lump sum positive inflow → capital repayment
    * Amount is known and equal to the initial loan amount
    * Timing is known = end of term
    * Unless borrower dies, repays early, or defaults

Q

Where might expenses and premiums be categorized?

A
  1. Expenses → tend to increase over time at a rate between price and earnings inflation → Guaranteed in terms of an index
  2. Premiums/contributions → negative liabilities
    * Fixed in monetary terms → negative benefit payments guaranteed in monetary terms
    * Expected to increase in line with inflation → negative benefits guaranteed in terms of an index

Q

What is a good asset match for liabilities guaranteed in money terms?

5

A
  • Conventional bonds of appropriate terms
  • Exact match is unlikely → exact timing of A proceeds unlikely to match exactly with L outgo
  • Available bonds may not be long enough in duration
  • Bonds should be of high quality since the benefit is guaranteed
  • Derivatives could be used → expensive + exact matching not always possible

Q

What is a good asset match for liabilities guaranteed in terms of an index?

2

A
  1. Index-linked bonds at an appropriate term
    * May not be available and index may not be the same as liabilities
  2. Equities and properties may provide a broad match

Q

What is a good match for discretionary liabilities?

A
  • Assets expected to produce a high real yield → equity or property
  • Consider policyholders’ expectations + provider’s risk appetite

Q

What is a good match for investment-linked liabilities?

3

A
  • Provider can avoid any investment matching problems by investing in the same assets used to determine benefits
  • If this requires tracking a market index (holding large numbers of small holdings) → it can be costly
  • Use collective investment schemes to track the investment or a derivative strategy

Q

How Does the Existence of Free Assets (Surplus) Affect the Investment Strategy of an Insurance Company?

7

A
  • Free assets provide a cushion against adverse investment experience.
  • With free assets, the insurer can depart from a matched position and potentially achieve a higher overall return.
  • Alternatively, insurers must use free assets to reduce risk and move to a more matched position.
  • Sufficient assets are needed → Investing in high-risk assets and moving away from a matched position increases the risk of not meeting future obligations and insolvency.
  • Competing uses of free assets:
    1. Writing new business
    2. Providing discretionary benefits
  • Opportunities to depart from a matched position for guaranteed liabilities are limited.
  • In some territories, mismatching of investment-linked liabilities may be restricted by law or regulation.
17
Q

How Can a Mismatching or Resilience Reserve Be Determined?

A
  1. Deterministic Approach
    * Select assets (A) to exactly match liabilities (L).
    * Recalculate A and L values under stressed economic factors (e.g., interest rate changes).
    * If the stressed value of A < stressed value of L, the difference is the mismatching reserve that should be held.
  2. Stochastic Approach
    * Perform stochastic simulation of market conditions using an economic scenario generator.
    * Inspect the tails of the stochastic output.
    * Determine the mismatch reserve as the amount of free assets needed to prevent insolvency at the desired probability level.
18
Q

How Might the Regulatory Framework Limit a Provider’s Investment Options?

A

TECH SCAM

  • Types of assets a provider can invest in
  • Extent to which mismatching is allowed
  • Currency matching requirement
  • Hold certain assets
  • Single counterparty risk management→ restriction on maximum exposure
  • Custodianship of assets (custodian holds investments and accounts for financial transactions)
  • Amount of any one asset held to demonstrate solvency may be restricted
  • Mismatching reserve requirements
19
Q

What is Pure Matching?

A
  • Structuring the flow of income and maturity proceeds from assets so they coincide precisely (nature, timing, and currency) with net liability outgo under all circumstances.
20
Q

Why is Pure Matching Not Always Possible?

4

A
  • Timing or amounts of asset proceeds or liability outgo may be uncertain.
  • Pure matching may require excessive investment in certain securities → prohibitive.
  • Pure matching may require zero-coupon bonds (ZCBs) with exact liability terms, which may not exist or be too expensive.
  • Some liabilities are very long-term, and suitable dated assets may not exist.
21
Q

What is Liability Hedging?

A
  • Assets are chosen to perform in a similar way to liabilities.
  • Aims to select assets that behave exactly like liabilities in all scenarios.
  • Usually not fully possible → Instead, liabilities are hedged against specific factors (e.g., currency matching, hedging unit-linked liabilities).
22
Q

What is Unit-Linked Liabilities Hedging?

A
  • Establish a portfolio of assets and calculate the price of each unit from the asset values.
  • Use this price to value units of liabilities, ensuring assets and liabilities remain aligned.
23
Q

What is Immunisation, basic explanation and conditions (3)?

A
  • Investing assets so that the present value (PV) of assets and liabilities remains immune to small interest rate changes.
  • Basic Explanation of Immunisation
    1. Used when pure matching is not possible → reduces risk of liabilities exceeding assets due to changing investment conditions.
    2. Assumes that securities exist with a uniform yield across all terms.
  • Conditions for immunisation
    1. V(A) = V(L); PV(A) = PV(L)
    2. Discounted mean term (DMT) of asset proceeds = DMT of liability outgo: tV^tA_t/V^tA_t
    3. Spread/convexity of assets > Spread of liabilities
    t^2V^tA_t/V^tA_t
24
Q

What are the Limitations of Classical Immunisation Theory?

A

TAMARAI

  • Timing of asset proceeds and liability outgoes may be uncertain.
  • Aimed at meeting monetary liabilities, but investors may need to match real liabilities.
  • Mismatch profits and losses are removed except for small second-order effects → limits investment in equities and property.
  • Assumes a flat yield curve and the same interest rate change across all terms.
  • Relies on small interest rate changes → may not protect against large changes.
  • Assets with suitable long DMT may not exist.

25
Q

What is an Asset-Liability Model (A-L Model)?

A
  • Deterministic or stochastic model that helps institutional investors set an investment strategy.
  • Defined by:
    1. Specified objective
    2. Measurable target
    3. Time horizon
    4. Confidence level
  • A-L model projects future cashflows of both assets and liabilities and values them.
  • The model is run iteratively to determine an optimal investment strategy.
  • Should be dynamic → allows for correlation between A and L cashflows.
26
Q

How Can the Success of an Investment Strategy Be Monitored Using an A-L Model?

A
  • Regular valuations.
  • Compare valuation results with projections from the modelling process.
  • Adjustments made to control the level of risk accepted by the strategy.
  • Essentially, compare experience with expectations
