The trial court (TC) in this case excluded the evidence of a business valuation expert because he had submitted a calculation of value report and was then asked to testify to it. The expert self-admitted that he would not testify to a calculation of value and had explained in his engagement letter that a valuation engagement would be required for testimony. Despite the exclusion by the TC and the self-admission of the inadequacy of a calculation of value for testimony purposes, the appellate court nevertheless remanded the case in part to determine whether the calculation of value met the requirements of Arizona Rule 702 for allowable evidence.
