Net risk

The remaining residual risk after the intrinsic hazards of the business or organisation have been reduced in terms of nature, scale and probability of occurrence by the precautions taken by the insured. Ascertaining the net risk is a part of risk assessment.

New business strain

Occurs when the early years’ premiums under a contract, less the initial expenses and any early claims, are not sufficient to cover the reserve, plus any explicit required solvency margin, that the company wishes to set up. An expanding life insurer may find that the unexpired premium reserve is increasing faster than it is being released making it difficult to achieve the required margin of solvency. Zillmerization allows for this situation. Reinsurance on a risk premium basis is another possible solution.

New for old policies

Cover for household contents where an item lost or destroyed would be replaced with a new item, with no deduction for wear and tear. It is ‘replacement as new’ but if the ‘new’ is superior to the ‘old’ the insured pays for ‘betterment’. Business insurance equivalent is the replacement clause. Sums insured must represent full replacement costs.

NHS indemnity

An indemnity provided by the Crown to pay for the financial consequences of alleged negligence on the part of medical practitioners occurring in NHS hospitals. It does not cover private practice, ‘Good Samaritan’ acts or other work undertaken outside the practitioner’s NHS contract and neither does it include General Medical Council or disciplinary hearings or any criminal charges resulting from clinical practice work in the NHS.

Night

A goods in transit policy warranted that vehicles would be in ‘locked garages at night’, except when employed on night journeys, but then never left unattended (A. Cohen & Co. Ltd v. Plaistow Transport Ltd (Graham, Third Party) (1968)). McKenna J. stated, obiter, that night should be construed by reference to lighting up time.

Night risk clause

Goods in transit clause to warrant that vehicles left loaded overnight must not be unattended unless locked and immobilised in accordance with any such provision in the policy. It may also be required that such vehicles be left either in a building or yard, which is also securely closed and locked, or in an attended official car park. See NIGHT.

Nipple leakage

Leakage through the failure of the nipple joints of boiler or pressure plant. The cost of repair can be covered as an extension to a boiler and pressure plant policy. The extension covers ‘self damage’ only. Damage consequent upon the leakage is not covered as separate water damage cover is available under burst pipes cover. See ADDITIONAL PERILS.
