The Life Insurance Company Setting
*Term life insurance
Provides what is considered “pure” mortality protection.
In exchange for each premium payment, the insurer provides coverage if death occurs during the premium payment period. Because the chance of death increases as the policyholder ages, premiums will increase as well.
The Life Insurance Company Setting
*Permanent life insurance
features a fixed premium that acts to levelize the policyholder’s outlay over the lifetime of the policy.
For a block of policies, the excess of early-year premiums over early-year claims adds to reserves. Thus, a key responsibility of the insurer is to invest the excess premiums at a sufficient rate of return. Because of this, permanent life insurance policies are considered to include what is known as a savings element, which represents the contribution of investment earnings to funding future policy claims.
The Life Insurance Company Setting
With traditional whole life insurance: an interest rate on reserves is implicit in the premium rate and is locked in at time of policy issuance.
Universal life insurance: in contrast, features a reserve that accumulates at company declared credited interest rates, which are periodically reset.
Variable life insurance: funnels premium dollars into separate accounts – segregated pools of bonds or stocks.
The Life Insurance Company Setting
*The two major asset classes in which life insurers invest are bonds and mortgages, because of their long maturities and the fact that most issues pay fixed rates of interest. Because of the latter characteristic, bonds and mortgages are referred to as fixed income investments.
Basic Principles of Asset/Liability Management
The value of a particular instrument, whether an asset or an insurance policy, depends on the timing, amount and certainty of its future cash flows and the time value of money. (The foundations of asset/liability management lie in the concept of immunization, which is based on duration)
Basic Principles of Asset/Liability Management
Requirements for Investment Returns
Perhaps the strictest return requirement is for policies that make a guarantee of minimum interest rates. For immediate annuities, this is the implicit interest rate defined by the sequence of periodic annuity benefit payments the policyholder is promised.
Interest Rate Risks
Historical Methods
By quantifying interest rate sensitivity, the duration measure allows ready evaluation of investment risk and can also indicate corrective actions. If durations are matched, a change in the level of interest rates is expected to have the same percentage impact on the values of both assets and liabilities so that surplus will be unaffected.
If asset duration is too low relative to liability duration, lower duration assets must be replaced with higher-duration assets. This is known as lengthening the duration, while the opposite is referred to as shortening the duration.
Historical Methods
Limitations of Duration
Immunization theory does recognize that duration matching requires rebalancing the asset portfolio, but the theoretically correct answer is to rebalance continuously. Frequent rebalancing is impractical and can involve exorbitant transaction costs.

Value at Risk (VaR) and Its Brethren
VaR specifies the maximum potential loss over a given time period for a specific chance of occurrence.
The Rise of Derivatives Usage
Derivatives Basics
There are two broad classes of derivatives: futures contracts and option contracts
If an option is in-the-money, so that the owner can buy for less than the current market price (with a call) or sell for more than the current market price (with a put), the option owner can exercise the option.
Best Practices in ALM
Select the Most Appropriate Metric
A metric is a measurement standard or yardstick for quantifying ALM risk.
The key criteria for choosing a metric are relevance, or the extent to which the metric captures the nature and extent of an insurer’s risk exposures, and actionability, or how the metric motivates and enables reparative actions.

A Case Study of Interest Rate Risk
An insurer’s greatest exposure to interest rate risk may derive from the single-premium deferred annuity (SPDA).
Challenges in Asset/Liability Management
Measurement Basis, Analytical Platform, Communication
Measurement Basis?
The purest representation of asset/liability dynamics is instead through economic values.
• *Economic Value: which measure assets and liabilities according to the cash flows they generate.
For an asset traded in the financial markets, the economic value is its market value. Market value is the amount of cash that can be immediately realized.
*For life insurance liabilities: a liability fair value is derived from its future cash flows, adjusted for risk as well as any other relevant economic characteristics.
Approaches to Asset/Liability Management
Investment Strategy
Approaches to Asset/Liability Management
Product Design
To the extent that a company must maintain adequate sales and inforce volume by issuing products whose design and pricing are dictated at least in some part by competitive considerations rather than economic imperatives, the asset-based approach will play a central role in the overall ALM framework.
Approaches to Asset/Liability Management
Holism
These focus on risk at the enterprise level, rather than at the product or line-of-business level as has been typical in past ALM practice.
Approaches to Asset/Liability Management
Reinsurance
Traditional reinsurance relies mainly on the same pooling-of-risks concept as does direct insurance, while reinsurance of investment risk is a form of financial intermediation.

• Traditional insurance risks are generally nonsystematic – that is, fluctuations in experience are random and average out over larger populations.
• In contrast, investment risk is largely systematic – all insured risks are strongly affected by certain common influences, like developments in the capital markets.
Emerging Methods and Metrics
Option Pricing
option pricing, the theory of the economic valuation of financial instruments whose cash flows depend on capital market conditions – that is, those containing options.
Option pricing theory dictates that economic valuation of any instrument that is not traded in the market (like an insurance liability) must also adhere to this methodology.
The option price of interest-sensitive liabilities can be determined by averaging the present value of future cash flows over the range of arbitrage-free interest rate scenarios.This technique produces an option-adjusted value that captures the cost of the options included.
Emerging Methods and Metrics
Dynamic Hedging
This approach, which is analogous to the immunization of interest rate risk, involves establishing a hedge portfolio with equity market sensitivities that match those of the liabilities.
There are five equity market sensitivities usually considered in dynamic hedging. Delta Gamma Vega Raho Theta,
Dynamic hedging requires only that the price or value sensitivities of the hedge portfolio and the liabilities are in alignment.
