B

Back-To-Back (F)

A way of referring to some combinations of two or more life assurance policies effected simultaneously.

An example is a temporary annuity "feeding" a regular premium endowment assurance ie you pay a single premium for the annuity which then pays the regular premiums for the endowment assurance.

 

Balance of Cost Scheme (H)

An occupational pension scheme where employees pay a fixed contribution (possibly zero) and where the employer meets the unknown balance of the cost of the scheme.

Virtually all UK final salary occupational pension schemes are balance of cost schemes.The (now) rare alternative is for members' contributions to be variable too.

 

Balance (G)

The ratio of the total premium receivable by a reinsurer under a surplus treaty to the reinsurer's maximum liability for any one claim, based on EML.

 

Base Period (G)

The period from which data is used, eg claims data used as the basis for future premium rates.

 

Base Values (G)

Values derived from an investigation over a base period.

 

Basis Point (E)

One hundredth of 1%. The term basis point is used in reference to interest rates and yields. For example, 20 basis points above a yield of 10.25% is a yield of 10.45%%.

 

Basis (A/D)

The set of assumptions (eg mortality rates, interest rates, price inflation) used in an actuarial calculation. A Strong basis is one that leads to conservative (ie high) estimates of liabilities. Conversely for a Weak basis.

 

Basis (F)

The set of assumptions the office has to make to assess the effect of writing life assurance business. It includes assumptions about expected mortality, investment returns and inflation. The assumptions required depend upon the product being considered, the method used and the purpose of the investigation.

At times it is helpful to have a broad description of the basis being used:

 

  • a strong basis is pessimistic (ie high liability value, low asset value)
  • a weak basis is optimistic (ie low liability value ... )
  • the premium basis is the basis which was used to assess premiums when the contract was sold, not the current premium basis
  • a realistic basis is the office's current best estimate of future expected experience

 

Bear Market (E)

A period of time during which investors are generally unconfident and stock market prices decline. Opposite of a bull market. A person who thinks that prices will fall is known as a "bear" and is said to have a "bearish" outlook. A bear is happy to go away and hide (preferably with some honey and condensed milk).

 

Bearer Security (E)

A security where possession of a certificate proves ownership and where the interest and the redemption proceeds must be claimed by the bearer or holder (eg Eurobonds). The "opposite" of bearer bonds is where a register of bond holders is kept (eg conventional gilts).

 

Beneficiary (N)

The person named in the policy to receive the insurance proceeds at the death of the insured.

 

Benefit Payments (F)

Amounts paid to the policyholder by the life office.

These are what it is all about as far as the policyholder is concerned.

 

Benefit (A/D)

A payment or series of payments made under specified circumstances from an insurance policy or pension scheme.

 

Best Advice (F)

A term used in connection with the Financial Services Act (FSA). Best advice covers a wide range of requirements to ensure that financial recommendations are appropriate for the client (eg "knowing the customer", informing the customer of the types of contract you can advise on). A slightly weaker set of requirements developed later are described as good advice.

 

Beta (E)

A measure of a stock's volatility relative to movements in the whole market.

 

Bid Basis (F)

A method of calculating unit prices appropriate for a contracting fund.

 

Bid Price (E)

The price at which a market maker offers to buy a security (ie the lower of the two prices quoted).

 

Bid Price (F)

This is the price a life insurance company uses to repurchase or "redeem" units from a unit-linked policyholder.

See Offer Price.

 

Bid-Offer Spread (F)

The difference between the offer price and the bid price in the context of a unit-linked policy. The bid price is lower often 5 % lower. The purpose of the spread is to make a charge to the policyholder to meet certain expenses (eg renewal commission) and to prevent frequent purchase and sale of units.

 

Big Bang (E)

Reform of Stock Market trading activity which occurred in October 1986.

 

Bill (E)

Binomial Model (D)

A mortality model based on the binomial distribution, which models the number of deaths recorded in a specified group of lives during a specified time period.

 

Black Monday (E)

19 October 1987. The day when the world's major stock markets crashed. As share prices fell, about one-third of the value of stock markets was wiped out in just two to three days, most of it happening on Black Monday.

 

Black Wednesday (E)

See "Golden Wednesday".

 

Black-Scholes Formula (E)

A widely used basis for valuing options. It takes into account most of the important factors (ie exercise price, underlying share price, time to expiry, interest rates and share price volatility), but fails to allow for dividends payable on the underlying security.

 

BLAGAB (F)

Bond (E)

A binding agreement for a borrower to pay a lender specified amounts of money at specified times. The term 'bonds' is often used to mean fixed interest securities such as conventional gilts, Eurobonds and debentures.

 

Bonus Earning Capacity (F)

A term used in the context of with-profit business. The term can be applied to an individual policy, a group of policies or even the whole life office.

At the beginning of the term of an individual policy, the bonus earning capacity is the future bonus rate(s) at which the present value of premiums equals the present value of benefits and expenses (and profit. if a profit is intended on the contract).

In the middle of the term of an individual policy, the bonus earning capacity is the future bonus rate(s) at which the present value of future premiums plus the current asset share equals the present value of future benefits and expenses (and profit, if a profit is intended on the contract).

The figures for individual policies can be aggregated to apply to cohorts.

The bonus earning capacity of an office is the future bonus rate(s) at which the value of assets equals the value of liabilities. This may be higher than the bonus earning capacity for the whole of the with-profit policies if an estate has been built up in respect of policies now off the books, or if profits are expected from non-profit or unit-linked business.

The shorter definition in the Core Reading is:

The bonus earning capacity of a block of contracts is the rate or rates of bonus that those contracts can sustain over their future lifetime, on the basis of a set of assumptions with regard to future experience.

 

Bonus Earning Power (BEP) (F)

A more common way of referring to bonus earning capacity.

 

Bonus Hunger (G)

The reluctance of policyholder under an NCD system to claim amounts of lower value than the potential increase in premiums.

 

Bonus Reserve Valuation (F)

This is a type of gross premium valuation that allows explicitly for future bonuses under with-profit contracts.

The phrases bonus reserve valuation and gross premium valuation are often used interchangeably. The phrase gross premium valuation is more general (and safer). For some purposes (some solvency investigations), a gross premium valuation technique will be used with no allowance, for future bonus.

 

Bonus (A/D)

An additional benefit in excess of the basic benefit, paid from a With Profit Policy.

 

Bonus (F)

A bonus is usually an addition to the contractual benefits under a with-profit life assurance contract. It arises either because of explicit loadings in the premiums or because a company's actual experience has been better than what it had assumed in pricing the contract. A company will usually have complete discretion over the level of bonuses it allocates to contracts. Sometimes companies allocate bonuses as cash amounts. However, enhancement of benefits is the most common method in the UK.

 

Bonus-Malus (G)

Effectively an NCD system which extends to negative bonuses. The system awards discounts for claim-free driving, but imposes surcharges when there are claims.

 

Bonuses (N)

Additions to benefits allotted by life offices to the with-profits policyholders from surplus (i.e. profit) in various ways and at various intervals.

 

Book Value (of Assets) (F)

The book value of a life insurance company's assets is the value at which it purchased them. In practice, companies modify the value so as to take into account part but usually not all of subsequent changes in capital values. In this case, it is better called adjusted book value. Cash may be included at face value.

Book value is also known as "historic cost".

 

Book Value (E)

The value shown in the accounts. It may be used to refer to any item (eg "book value of assets"), or specifically the net asset value (ie the residual accounting value of the company which belongs to shareholders).

 

Bordereau (G)

Bull Market (E)

A period of time during which investors are generally confident and stock market prices increase.Opposite of a bear market. A person who thinks that prices will rise is known as a "bull" and is said to have a "bullish" outlook. A bull is happy to charge ahead.

 

Bulldog (E)

A sterling denominated bond issued by an overseas borrower in the traditional UK bond market, ie a foreign bond in the UK bond market.

 

Burning Cost Method (G)
