Upon conclusion of a contingent fee matter for which a writing is required under this paragraph, the lawyer shall provide the client with a written statement explaining the outcome of the matter and, if there is a recovery, showing the remittance to the client and the method of its determination. At any time prior to the occurrence of the contingency, the lawyer shall, within twenty days after either 1) the termination of the attorney-client relationship or 2) receipt of a written request from the client when the relationship has not terminated, provide the client with a written itemized statement of services rendered and expenses incurred; except, however, that the lawyer shall not be required to provide the statement if the lawyer informs the client in writing that he or she does not intend to claim entitlement to a fee or expenses in the event the relationship is terminated before the conclusion of the contingent fee matter.
