In the related field of private contracts, studies have shown that a contract with an unreliable negotiating partner not only increases the likelihood that a contract will be terminated prematurely, but also increases the likelihood that a fixed-term termination clause will be included in the contract. Footnote 72 Agreements that come into force following termination, withdrawal or replacement and those that terminate after the expiry of the clauses imply the reliability of a party. The results can be illustrated by comparing estimated survival curves or cumulative hazard curves. The survival curve at time t represents the probability that an chord will last up to t, as a function of its duration up to t. The cumulative danger in time t is the probability that an agreement will expire in or before t. 97 Cf.
