Business Combination, Admin Fee Receivables [Abstract]
Business Combination, Acquired Receivables, Description													The fair value of current assets acquired also includes an adjustment of $35.0 million for administrative fees related to customer purchases that occurred prior to the acquisition date but not reported to MHA until after the acquisition date. In the ordinary course, these administrative fees are recorded as revenue when reported; however, GAAP accounting for business acquisitions requires the Company to estimate the amount of purchases occurring prior to the acquisition date and record the fair value of the administrative fees to be received from those purchases as an accounts receivable at the date of acquisition.
Business Combination, Liability Related to Acquired Receivables, Description													The Company also recorded a fair value liability of $8.6 million included in current liabilities related to corresponding revenue-share obligation owed to customers that generated the administrative fees.
