Escrow receivable, description			The terms of the Escrow Agreement provide that if, as of September 29, 2018, there were funds remaining in the escrow account, then the escrow account would be reduced by the difference, if a positive number, of (i) $2.5 million minus (ii) the aggregate amount of all escrow claims asserted by Mylan prior to this date that had either been paid out of the escrow account or were pending as of such date, and, within two business days of such date, the Escrow Agent would disburse such difference, if a positive number, to us. In addition, within two business days of March 29, 2019, the Escrow Agent was required to release any funds remaining in the escrow account to us minus any amounts being reserved for escrow claims asserted by Mylan prior to such date. Upon the resolution of any pending escrow claims, the Escrow Agent would then, within two business days of receipt of joint instructions or a final order from a court (as described in the Escrow Agreement) disburse such reserved amount to the parties entitled to such funds. As described below, in August 2018, Mylan asserted an indemnification claim against us. Accordingly, the distributions were not released to us on September 29, 2018 or March 29, 2019.
