33Therefore, the requirement that a contractual term must be drafted in plain intelligible language means that the contract should indicate transparently and specifically how the mechanism to which the relevant term relates is to function and, where appropriate, the relationship between that mechanism and that provided for by other contractual terms, so that that consumer is in a position to evaluate, on the basis of clear, intelligible criteria, the economic consequences for him of entering into the contract (judgment of 20 September 2017, Andriciuc and Others, C‑186/16, EU:C:2017:703, paragraph 45).
