Asset/liability modeling

Last updated

Asset/liability modeling is the process used to manage the business and financial objectives of a financial institution or an individual through an assessment of the portfolio assets and liabilities in an integrated manner. [1] The process is characterized by an ongoing review, modification and revision of asset and liability management strategies so that sensitivity to interest rate changes are confined within acceptable tolerance levels. [1]

Different models use different elements based on specific needs and contexts. An individual or an organization may keep parts of the ALM process and outsource the modeling function or adapt the model according to the requirements and capabilities of relevant institutions such as banks, which often have their in-house modeling process. [2] There is a vast array of models available today for practical asset and liability modeling and these have been the subject of several research studies. [3]

Asset/liability modeling (pension)

In 2008, a financial crisis drove the 100 largest corporate pension plans to a record $300 billion loss of funded status. [4] In the wake of those losses, many pension plan sponsors reexamined their pension plan asset allocation strategies, to consider risk exposures. A recent study indicates that many corporate defined benefit plans fail to address the full range of risks facing them, especially the ones related to liabilities. Too often, the study says, corporate pensions are distracted by concerns that have nothing to do with the long-term health of the fund. [5] Asset/liability modeling is an approach to examining pension risks and allows the sponsor to set informed policies for funding, benefit design and asset allocation.

Asset/liability modeling goes beyond the traditional, asset-only analysis of the asset-allocation decision. Traditional asset-only models analyze risk and rewards in terms of investment performance. Asset/liability models take a comprehensive approach to analyze risk and rewards in terms of the overall pension plan impact. An actuary or investment consultant may look at expectations and downside risk measures on the present value of contributions, plan surplus, excess returns (asset return less liability return), asset returns and any number of other variables. The model may consider measures over 5-, 10- or 20-year horizons, as well as quarterly or annual value at risk measures.

Pension plans face a variety of liability risks, including price and wage inflation, interest rate, and longevity. While some of these risks materialize slowly over time, others – such as interest rate risk – are felt with each measurement period. Liabilities are the actuarial present value of future plan cash flows, discounted at current interest rates. Thus, asset/liability management strategies often include bonds and swaps or other derivatives to accomplish some degree of interest rate hedging (immunization, cash flow matching, duration matching, etc.). Such approaches are sometimes called “liability-driven investment” (LDI) strategies. In 2008, plans with such approaches strongly outperformed those with traditional “total return” seeking investment policies. [6]

Asset/liability studies

Successful asset/liability studies:

Historically, most pension plan sponsors conducted comprehensive asset/liability studies every three to five years, or after a significant change in demographics, plan design, funding status, sponsor circumstances, or funding legislation. Recent trends suggest more frequent studies and/or a desire for regular tracking of key asset/liability risk metrics in between formal studies.

Additional challenges

In the United States, the Pension Protection Act of 2006 (PPA) introduced stricter standards on pension plans, requiring higher funding targets and larger contributions from plan sponsors. With growing deficits and PPA funding requirements looming large, there is an unprecedented need for asset/liability modeling and overall pension risk management.

Asset/liability modeling for individuals

Some financial advisors offer Monte Carlo simulation tools aimed at helping individuals plan for retirement. These tools are designed to model the individual’s likelihood of assets surpassing expenses (liabilities).

Proponents of Monte Carlo simulation contend that these tools are valuable because they offer simulation using randomly ordered returns based on a set of reasonable parameters. For example, the tool can model retirement cash flows 500 or 1,000 times, reflecting a range of possible outcomes. [7]

Some critics of these tools claim that the consequences of failure are not laid out and argue that these tools are no better than typical retirement tools that use standard assumptions. Recent financial turmoil has fueled the claims of critics who believe that Monte Carlo simulation tools are inaccurate and overly optimistic. [8]

An actuary is a business professional who deals with the measurement and management of risk and uncertainty. The name of the corresponding field is actuarial science. These risks can affect both sides of the balance sheet and require asset management, liability management, and valuation skills. Actuaries provide assessments of financial security systems, with a focus on their complexity, their mathematics, and their mechanisms.

The Pension Benefit Guaranty Corporation (PBGC) is a United States federally chartered corporation created by the Employee Retirement Income Security Act of 1974 (ERISA) to encourage the continuation and maintenance of voluntary private defined benefit pension plans, provide timely and uninterrupted payment of pension benefits, and keep pension insurance premiums at the lowest level necessary to carry out its operations. Subject to other statutory limitations, PBGC's single-employer insurance program pays pension benefits up to the maximum guaranteed benefit set by law to participants who retire at 65. The benefits payable to insured retirees who start their benefits at ages other than 65 or elect survivor coverage are adjusted to be equivalent in value. The maximum monthly guarantee for the multiemployer program is far lower and more complicated.

In mathematical finance, a Monte Carlo option model uses Monte Carlo methods to calculate the value of an option with multiple sources of uncertainty or with complicated features. The first application to option pricing was by Phelim Boyle in 1977. In 1996, M. Broadie and P. Glasserman showed how to price Asian options by Monte Carlo. An important development was the introduction in 1996 by Carriere of Monte Carlo methods for options with early exercise features.

<span class="mw-page-title-main">Asset allocation</span> Investment strategy

Asset allocation is the implementation of an investment strategy that attempts to balance risk versus reward by adjusting the percentage of each asset in an investment portfolio according to the investor's risk tolerance, goals and investment time frame. The focus is on the characteristics of the overall portfolio. Such a strategy contrasts with an approach that focuses on individual assets.

Liability-driven investment policies and asset management decisions are those largely determined by the sum of current and future liabilities attached to the investor, be it a household or an institution. As it purports to associate constantly both sides of the balance sheet in the investment process, it has been called a "holistic" investment methodology.

Asset and liability management is the practice of managing financial risks that arise due to mismatches between the assets and liabilities as part of an investment strategy in financial accounting.

The chief investment officer (CIO) is a job title for the board level head of investments within an organization.

At retirement, individuals stop working and no longer get employment earnings, and enter a phase of their lives, where they rely on the assets they have accumulated, to supply money for their spending needs for the rest of their lives. Retirement spend-down, or withdrawal rate, is the strategy a retiree follows to spend, decumulate or withdraw assets during retirement.

Quantitative analysis is the use of mathematical and statistical methods in finance and investment management. Those working in the field are quantitative analysts (quants). Quants tend to specialize in specific areas which may include derivative structuring or pricing, risk management, algorithmic trading and investment management. The occupation is similar to those in industrial mathematics in other industries. The process usually consists of searching vast databases for patterns, such as correlations among liquid assets or price-movement patterns. The resulting strategies may involve high-frequency trading.

Dedicated portfolio theory, in finance, deals with the characteristics and features of a portfolio built to generate a predictable stream of future cash inflows. This is achieved by purchasing bonds and/or other fixed income securities that can and usually are held to maturity to generate this predictable stream from the coupon interest and/or the repayment of the face value of each bond when it matures. The goal is for the stream of cash inflows to exactly match the timing of a predictable stream of cash outflows due to future liabilities. For this reason it is sometimes called cash matching, or liability-driven investing. Determining the least expensive collection of bonds in the right quantities with the right maturities to match the cash flows is an analytical challenge that requires some degree of mathematical sophistication. College level textbooks typically cover the idea of “dedicated portfolios” or “dedicated bond portfolios” in their chapters devoted to the uses of fixed income securities.

The Wilkie investment model, often just called Wilkie model, is a stochastic asset model developed by A. D. Wilkie that describes the behavior of various economics factors as stochastic time series. These time series are generated by autoregressive models. The main factor of the model which influences all asset prices is the consumer price index. The model is mainly in use for actuarial work and asset liability management. Because of the stochastic properties of that model it is mainly combined with Monte Carlo methods.

In finance, active return refers the returns produced by an investment portfolio due to active management decisions made by the portfolio manager that cannot be explained by the portfolio's exposure to returns or to risks in the portfolio's investment benchmark; active return is usually the objective of active management and subject of performance attribution. In contrast, passive returns refers to returns produced by an investment portfolio due to its exposure to returns of its benchmark. Passive returns can be obtained deliberately through passive tracking of the portfolio benchmark or obtained inadvertently through an investment process unrelated to tracking the index.
