English to Spanish Bus/Financial Law (general)

No sé como traducir la frase "growing amount of insurance" en el siguiente contexto:
There are different types of term policies. Level term provides a consistent amount of insurance. Decreasing term, which is an ideal type of insurance to cover any shrinking debt obligation, starts with a specified face amount which decreases annually until it reaches zero at policy expiration. Increasing term provides a growing amount of insurance, but the need for this type of protection is rare.
