Statements made on an application that the insured guarantees to be true are

Material facts are important pieces of information that affect the underwriting of an insurance policy but do not necessarily have the same binding guarantee as warranties. While the insured must disclose material facts, these do not carry the same legal implications as warranties, which require absolute truthfulness.

Waivers refer to the voluntary relinquishment of a known right, claim, or privilege. In the context of insurance, waivers are not related to the truthfulness of statements made by the insured but rather to the insurer's decision to forgo a right, such as the right to enforce a policy term. Therefore, waivers do not correlate with the guaranteed truths of statements made by the insured.

Estoppel is a legal principle that prevents a party from arguing something contrary to a claim made or implied by their previous actions or statements. While estoppel can arise in insurance contexts, it does not pertain to the guaranteed truth of statements made on an application, which is specifically defined as warranties.
