Growing Degree Days (GDD)

Weather index calculated by subtracting a reference temperature (e.g. 50°F or 10°C) from the average daily temperature. Each degree of ‘warmth’ is a growing degree day (GDD). The deviations from reference temperature benchmark a biological process, such as insect development. ‘Warm’ temperatures necessitate the use of costly pesticides to protect crops against agricultural pests. The payout is the tick multiplied by the difference between the GDD level stated in the contract (i.e. the strike) and the cumulative GDDs for the contract period.

Growth bond/capital bond

Fixed term investments, typically between three and five years, where a single premium life contract, with only nominal life cover, guarantees a minimum capital growth at maturity. It is a collective investment scheme that produces economies of scale for small investors. Investors pay tax at the basic rate and no additional tax on maturity. Higher tax payers may face a ‘top slice’ on any gain made on the bond.

Guarantee

(i) A written undertaking given by one party to another to answer for the fulfillment of the obligations of a third party. (ii) A facultative reinsurance.
***
REINSURANCE: Facultative Reinsurance.
***
UK: Promise to answer for the debt or default of another person. It is unenforceable unless evidenced in writing. The party giving the guarantee is the guarantor or surety (an insurer), the person receiving is the guarantee or creditor (e.g. the employer) and the person whose debt or performance, etc., is guaranteed is the principal (e.g. the employee). A fidelity guarantee policy may be either insurance by way of indemnity only, or a combination of both indemnity and guarantee in which case the law of insurance applies as between the insurer and the insured (the employer), but guarantee law applies between the insurer and the principal (the employee). The policy is one of ‘insurance only’ if effected without the constructive knowledge and consent of the principal. See INSURANCE GUARANTEE; PURE GUARANTEE.

Guarantee endorsement

Insurance policy endorsement covering the policyholder’s interest in mortgaged property providing that, if the insurer becomes insolvent, the reinsurer will pay any claim due directly to the mortgagee and/or policyholder. The endorsement is also called the mortgagee endorsement and conceptually is similar to the cut-through clause.
