Wind risk

The risk that wind speed variations will reduce the volume of electricity generated by wind farms and therefore sales for wind power companies. The risk can be managed by a weather derivative based on wind power indices (WPIS). The average value of the index over any 12-month period is 100 in a normal year. An annual value of 95 indicates that the index is 5 per cent below normal for the region and leads to a payout. Wind farm developers, operators and financiers may all hedge against the wind risk.

Winding up

Closing of an occupational pension scheme, usually done by buying annuities for all members, including deferred annuities. Alternatively all assets and liabilities can be transferred to another scheme in accordance with the scheme rules and any relevant laws. There are statutory provisions to determine when winding up commences for statutory purposes (Occupational Pension Schemes (Winding Up) Regulations 1996, Regulation 2 (SI 1996/3126)).

Windscreen breakage

Under private comprehensive car policies, insurers agree that, if a claim for damage consists solely of damage to the windscreen or windows, payment will be made without prejudice to the insured’s entitlement to no claim discount.
