Investments
Investments: 20 technical terms explained – definition, synonyms and legal basis.
Equity Risk
Synonyms: Aktienrisiko
Equity risk is the risk of a loss in value from equity investments due to price fluctuations in capital markets, and is a sub-risk of the market risk module under Solvency II.
Concept
Equity risk refers to the risk that the value of an insurer’s equity investments changes adversely as a result of price fluctuations in capital markets. It is one of the key sub-risks within market risk.
Treatment under Solvency II
Within the Solvency Capital Requirement (SCR) framework under Solvency II, equity risk is quantified separately within the market risk module. A distinction is made between “Type 1” equities (listed equities from OECD and EEA member states) and “Type 2” equities (all other equities, including unlisted and alternative investments), which are subject to different stress factors.
Management
Insurers manage equity risk through diversification across sectors and regions, hedging strategies using derivatives, and by setting a strategic equity allocation within asset allocation that is appropriate to their risk-bearing capacity.
Legal basis: EU: Solvency II Delegated Regulation (EU) 2015/35
Asset Allocation
Synonyms: Asset Allocation
Asset allocation is the strategic distribution of an investment portfolio across different asset classes to optimize return and risk.
Concept
Asset allocation refers to the strategic distribution of an investor’s capital — such as an insurer’s — across different asset classes including bonds, equities, real estate, and alternative investments. The goal is to construct a portfolio optimized for the desired return-risk profile.
Strategic versus Tactical Asset Allocation
A distinction is made between strategic asset allocation, which sets long-term target weights per asset class, and tactical asset allocation, which allows short-term deviations from these targets to exploit market opportunities.
Relevance for Insurers
For insurance companies, asset allocation is materially shaped by the structure of liabilities (duration, liquidity needs, guarantees) and by regulatory solvency requirements, and is closely intertwined with asset liability management.
Asset Backed Securities (ABS)
Synonyms: ABS
Asset backed securities are securities collateralized by a pool of receivables or other assets, with payments to investors serviced from the cash flows they generate.
Concept
Asset backed securities (ABS) are structured securities collateralized by a pool of assets — such as loan receivables, lease receivables, or credit card receivables. Interest and principal payments to investors are serviced from the cash flows generated by these underlying receivables.
Structure
In a securitization transaction, the receivables are typically transferred to a purpose-built special purpose vehicle (SPV), which issues the ABS. This separates the credit risk of the underlying receivables from the balance sheet risk of the original holder of the receivables.
Relevance for Insurers
Insurance companies invest in ABS as institutional investors to diversify their investment portfolios and access additional sources of yield. Careful credit and structural due diligence, as well as the regulatory treatment under Solvency II (spread risk, securitization exposure), are of particular importance.
Asset Liability Management (ALM)
Synonyms: ALM
Asset liability management is the integrated management of an insurer's investments and liabilities to limit interest rate, liquidity, and duration mismatch risks.
Concept
Asset liability management (ALM) refers to the integrated, coordinated management of both sides of an insurer’s balance sheet. The goal is to structure investments so that they closely match the characteristics of the liabilities — particularly regarding payment timing, duration, and interest rate sensitivity.
Objective
Effective ALM aims to minimize interest rate risk, liquidity risk, and duration mismatches between investments and obligations. This is of central importance especially in life insurance, where long-tail guaranteed liabilities exist.
Regulatory Context
Under Solvency II, ALM considerations feed directly into the calculation of interest rate risk and into the Own Risk and Solvency Assessment (ORSA). A robust ALM framework is regarded as a core component of a sound risk management system.
Asset Liability Modelling
Synonyms: ALM Modelling
Asset liability modelling is the simulation-based analysis of the interaction between an insurer's investments and liabilities under various capital market and business scenarios.
Concept
Asset liability modelling refers to the use of stochastic and deterministic simulation models to analyze the interaction between an insurer’s investments and liabilities under different capital market, interest rate, and underwriting scenarios.
Application
Asset-liability models are typically used to project metrics such as future solvency capital requirements, the development of policyholder bonuses, and the impact of stress scenarios on capital resources. These models frequently form the technical basis for the Own Risk and Solvency Assessment (ORSA).
Significance
Robust asset liability modelling enables management to make informed decisions on investment strategy, product design, and reinsurance needs, and to safeguard the company’s long-term financial stability.
Asset Management
Synonyms: Investment Management
Asset management is the professional management of investments on behalf of investors, including investment decisions, monitoring, and reporting.
Concept
Asset management refers to the professional management of investments on behalf of investors, including investment decisions, ongoing monitoring, risk control, and reporting. It can be carried out either internally by dedicated investment departments or externally by specialized asset managers.
Asset Management at Insurers
Insurance companies engage in asset management to invest the premiums and reserves entrusted to them profitably while maintaining an appropriate level of security. Larger insurance groups frequently establish their own asset management subsidiaries, which manage both the group’s own capital and third-party funds.
Regulatory Framework
An insurer’s asset management is subject to the supervisory “prudent person principle” under Solvency II, according to which investments must be made in a manner that ensures the security, liquidity, and profitability of the overall portfolio.
Asset-Liability Mismatch Risk
Synonyms: Duration Mismatch Risk
Asset-liability mismatch risk is the risk that an insurer's investments and liabilities do not sufficiently align in terms of maturity, interest rate sensitivity, or currency.
Concept
Asset-liability mismatch risk describes the danger that the maturity structure, interest rate sensitivity, or currency of an insurer’s investments do not sufficiently align with those of its liabilities. Such a mismatch can result in payment obligations that cannot be met on time or only at a loss.
Causes
Mismatch risk arises, among other things, from differing durations of assets and liabilities, from interest rate guarantees in life insurance contracts not backed by correspondingly long-dated investments, or from currency mismatches in international business.
Management
Insurers address asset-liability mismatch risk through active asset liability management, the use of interest rate and currency derivatives for hedging, and an investment strategy aligned with the structure of liabilities. Under Solvency II, this risk is quantified within the market risk module.
Cash Reserve (Liquidity Reserve)
Synonyms: Barreserve, Liquidity Reserve
The cash reserve is the holding of immediately available liquid funds that an insurer maintains to meet short-term payment obligations.
Concept
The cash reserve is the holding of cash and immediately or short-term available liquid funds that an insurer maintains in order to be able to meet ongoing and short-term due payment obligations, particularly claims payments, at all times.
Relevance for Liquidity Management
Appropriately sizing the cash reserve is a central element of an insurer’s liquidity management: too low a cash reserve carries the risk of having to sell investments at an unfavorable time to meet payment obligations, while an excessively high cash reserve impairs investment performance, since cash typically earns a lower return than other asset classes.
Relevance in Major Loss Events
In the case of natural catastrophes or other major loss events involving a large number of simultaneously due payment obligations, an adequate cash reserve is particularly important to ensure the insurer’s solvency even under stress conditions, which is why liquidity planning is regularly a component of an insurer’s risk management and stress testing.
Benchmark
Synonyms: Benchmark Index
A benchmark is a reference standard, typically an index, against which the performance of an investment or portfolio is measured.
Concept
A benchmark is a reference standard, usually a market index or a reference portfolio composed of several indices, against which the relative performance and risk profile of an investment or investment portfolio is measured and assessed.
Relevance for Investment Management
Insurers typically set a specific benchmark for each asset class within their strategic asset allocation (such as an equity index for the equity allocation or a bond index for the fixed-income allocation), against which actual portfolio performance is regularly compared.
Active versus Passive Management
The benchmark is also the starting point for the distinction between active management, which seeks to outperform the benchmark, and passive management, which aims to replicate the benchmark’s performance as closely as possible; the difference between actual portfolio performance and benchmark performance is referred to as tracking error or alpha.
Valuation Reserve (Hidden Reserve)
Synonyms: Bewertungsreserve, Hidden Reserve
A valuation reserve is the hidden reserve that arises when the market value of an investment exceeds its lower statutory book value.
Concept
A valuation reserve is the difference between the current market value (fair value) of an investment and its lower statutory book value determined under the historical cost principle; it represents a hidden reserve not disclosed on the balance sheet.
How It Arises
Valuation reserves typically arise for bonds when current market interest rates are below the bond’s nominal coupon rate, and for equities and real estate whose market value has risen since acquisition, while the book value continues to reflect historical acquisition cost less depreciation.
Policyholder Participation in Life Insurance
In German life insurance, policyholders are, under Section 153 of the German Insurance Contract Act (VVG), generally entitled to a share of the valuation reserves attributable to their respective contract’s investments; this participation is paid out at maturity, surrender, or death and was a politically contentious topic during periods of low interest rates, since payouts to departing policyholders can come at the expense of the remaining book of business.
Creditworthiness
Synonyms: Bonität
Creditworthiness is a debtor's ability and willingness to meet its financial obligations fully and on time, and forms the basis of rating and credit risk assessment.
Concept
Creditworthiness refers to a debtor’s ability and willingness — such as a bond issuer, a contracting party, or a borrower — to fully and timely meet its financial obligations.
Measuring Creditworthiness
Creditworthiness is frequently assessed by external rating agencies using standardized rating scales (such as AAA to D), incorporating metrics like leverage, interest coverage, liquidity, and profitability, as well as qualitative factors such as management quality and market position.
Relevance for Insurers
For insurers, creditworthiness assessment is central both to investment management (default risk of bonds and other receivables) and to credit insurance (the paying capacity of the buyers of the insured companies’ goods), as well as to the assessment of reinsurers and counterparties, and it also feeds into capital requirements under Solvency II.
Cash Flow Matching
Synonyms: Cash Flow Matching
Cash flow matching is an investment strategy aligning the timing and amount of investment cash flows with expected future insurance benefit payments.
Concept
Cash flow matching is an asset-liability management investment strategy that aligns the timing and amount of expected cash flows from investments (interest payments and redemptions) as closely as possible with the expected future payment obligations arising from insurance contracts.
Mechanism
Unlike duration matching, which merely equalizes the average interest rate sensitivity of assets and liabilities, cash flow matching aims for the closest possible correspondence of individual payment dates and amounts, so that maturing investments directly cover the corresponding insurance benefits due, without needing to sell assets prematurely or raise additional funds.
Applications and Limitations
Cash flow matching is used particularly for annuity products with well-predictable payment obligations; practical implementation is, however, constrained by the limited availability of investments with exactly matching maturities and by uncertainties in forecasting technical cash flows (such as lapse or longevity risk), which is why a combination of cash flow matching and duration matching is frequently used in practice.
Covered Bond
Synonyms: Pfandbrief
A covered bond is a secured bond protected, in addition to issuer liability, by a ring-fenced pool of high-quality collateral assets.
Concept
A covered bond is a secured bond issued by a credit institution, under which investors have not only a claim against the issuer but are additionally protected by a cover pool, ring-fenced from the rest of the balance sheet, of high-quality assets, usually mortgage loans or public-sector loans.
Dual Recourse
The central feature of covered bonds is the dual recourse principle: in the event of the issuer’s insolvency, bondholders have priority access to the cover pool while simultaneously continuing to be able to pursue claims as ordinary creditors against the issuer’s remaining insolvency estate, giving covered bonds a significantly lower default risk compared to unsecured bonds.
Relevance for Insurers’ Investments
Due to their low default risk and favorable regulatory treatment under Solvency II, covered bonds such as the German Pfandbrief are among the preferred investment instruments for insurers, who require long-term, safe, and predictable investments to back their technical liabilities.
Derivative
Synonyms: Derivat
A derivative is a financial instrument whose value is derived from an underlying asset, used by insurers primarily to hedge investment risks.
Concept
A derivative is a financial instrument whose value is derived from the performance of an underlying asset (such as a share, an interest rate, an index, or a currency), without the underlying asset itself needing to be acquired directly.
Common Types of Derivatives
Derivatives most commonly used in the insurance industry include interest rate swaps to hedge interest rate risk, forward foreign exchange contracts to hedge currency risk in international investments, and options to hedge equity price risk, for example in connection with guaranteed maturity benefits of unit-linked life insurance products.
Regulatory Treatment
The use of derivatives by insurers is subject to regulatory restrictions that generally limit their use to purposes of risk reduction and efficient portfolio management; under Solvency II, the risk associated with derivative positions is capitalized under the market risk module of the standard formula or an internal model, with the risk-mitigating effect of a hedge transaction recognized under certain conditions.
Diversification
Synonyms: Diversifikation
Diversification reduces the overall risk of a portfolio or insurance book by spreading exposure across weakly correlated risks, asset classes, or lines of business.
Concept
Diversification is the principle of reducing the overall risk of a portfolio or insurance book by spreading exposure across a large number of, as far as possible, weakly correlated individual risks, asset classes, regions, or lines of business, so that adverse developments in one area are at least partly offset by stable or positive developments in other areas.
Diversification in Investments
In investments, diversification is achieved by spreading exposure across different asset classes (equities, bonds, real estate), regions, industries, and issuers, which can reduce unsystematic, issuer-specific risk, while systematic market risk cannot be eliminated through diversification.
Diversification in Insurance and under Solvency II
In insurance business, diversification arises from pooling a large number of independent or weakly correlated individual risks within a line of business as well as from spreading exposure across multiple lines and regions; the Solvency II standard formula explicitly accounts for diversification effects through correlation matrices when aggregating capital requirements for the individual risk modules, thereby reducing the overall capital requirement of a diversified insurer.
Duration
Synonyms: Interest Rate Sensitivity
Duration measures the average capital-weighted maturity of a fixed- income security or portfolio and its sensitivity to interest rate changes.
Concept
Duration is a metric that measures the average, present-value-weighted maturity of a fixed-income security’s or portfolio’s cash flows, and simultaneously serves as an approximate measure of its sensitivity to changes in the market interest rate level.
Macaulay and Modified Duration
Macaulay duration expresses the weighted average remaining time to cash flows in years, while the modified duration derived from it approximates the percentage change in a security’s value for a one-percentage-point change in the market interest rate; the higher the duration, the more strongly a security’s market value reacts to interest rate changes.
Relevance for Asset-Liability Management
In life insurance, matching the duration of investments (assets) to the duration of technical liabilities is a central element of asset-liability management, since a duration mismatch exposes the undertaking to significant interest rate risk, which can be reflected in both the statutory accounts and the regulatory balance sheet under Solvency II.
ESG (Environmental, Social, Governance)
Synonyms: Environmental Social Governance
ESG refers to environmental, social, and governance criteria that insurers must increasingly consider in investments, underwriting, and regulatory disclosure.
Concept
ESG stands for Environmental, Social, and Governance and refers to a set of criteria for assessing the ecological, social, and governance-related sustainability of companies, investments, and business activities.
Relevance for Insurers’ Investments
In investment management, ESG criteria are increasingly integrated systematically into investment decisions, for example through the exclusion of certain industries (negative screening), the targeted preference for sustainable investments (positive screening), or active influence on companies as a shareholder (engagement); this is regulatorily flanked in particular by the EU Sustainable Finance Disclosure Regulation (SFDR) and the EU Taxonomy Regulation.
Relevance for Underwriting and Governance
Beyond pure investment management, ESG criteria are also gaining importance in underwriting, for example in assessing climate-related natural hazard risk or in deliberately declining to insure particularly climate-damaging activities, as well as in corporate governance, where supervisory authorities are increasingly demanding the integration of sustainability risks into insurers’ risk management and governance systems under Solvency II.
Net Investment Return (Nettoverzinsung)
Synonyms: Nettoverzinsung, Net Investment Yield
The net investment return is the actual investment yield achieved by a life insurer after deducting investment management expenses, measured relative to the average book value of investments held.
Concept
The net investment return refers to the actual return earned by a life insurer on its total investments within a financial year, calculated as the ratio of net investment income (after deducting investment management expenses, but before accounting for valuation reserves) to the average book value of investments held.
Relevance for Policyholder Bonus Participation
The net investment return is one of the most important indicators for assessing a life insurer’s earnings power, as it directly reflects the company’s ability to grant policyholders an attractive bonus participation beyond the guaranteed technical interest rate. In a sustained low-interest-rate environment, the net investment return tends to come under pressure, particularly as older, higher-yielding investments mature and must be replaced with lower-yielding new investments.
Distinction from the Running Average Yield
The net investment return must be distinguished from the running average yield, which considers only recurring, current investment income (e.g., interest and dividends) without realized gains and losses from the sale of investments, and thus represents a more stable but less complete indicator of investment earnings power.
Corporate Bond
Synonyms: Unternehmensanleihe
A corporate bond is a fixed-income security issued by a company and one of the most important asset classes in insurers' investment portfolios.
Concept
A corporate bond is a fixed-income security through which a company raises debt capital on the capital market, undertaking in return to make regular interest payments and to repay the nominal amount at maturity.
Relevance as an Asset Class for Insurers
Due to their higher yield relative to government bonds at a calculable level of risk, corporate bonds are among the most significant asset classes in insurers’ investment portfolios, particularly in life insurance, where they help meet long-term guarantee obligations.
Credit Risk and Rating
The issuer’s creditworthiness is decisive for a corporate bond’s default risk; rating agencies distinguish investment-grade bonds (rated BBB- or better) from high-yield bonds (ratings below investment grade), with regulatory capital requirements under Solvency II assessing the spread risk of corporate bonds largely as a function of their rating and remaining maturity.
Interest-Bearing Assets
Synonyms: Zinsträger
Interest-bearing assets are the capital of an insurance company available for yield-generating investment; on the balance sheet they mainly comprise own funds and technical provisions.
Concept
Interest-bearing assets refers to the capital available for yield-generating investment within an insurance company’s investment business. On the balance sheet, it mainly consists of own funds and technical provisions – particularly the mathematical reserve in life insurance.
Relevance for investment
The volume of interest-bearing assets determines the extent to which an insurer can generate investment income to fund guaranteed benefits and produce surplus. The larger the interest-bearing assets relative to guaranteed obligations, the greater the scope for interest surplus.
Practical relevance
In life insurance, interest-bearing assets grow continuously with the stock of technical provisions, requiring a long-term investment strategy focused on matching the duration of assets and liabilities.
