[1] | The total anticipated cash flow includes a transaction price of $120.0 million for the contractual obligations under the CSA for the Manufacturing Services and the Next-Gen R&D Services performance obligations and $602.3 million for future supply of Tyvaso DPI over the remaining term of the CSA.
[2] | The Manufacturing Services performance obligation will be recognized as control of manufactured products is transferred to UT. The modification did not result in a cumulative catch-up adjustment as a result of the revenue being deferred for the performance obligations that were affected by the modification. The allocation of the transaction price for the Manufacturing Services includes a material right related to the Company’s estimated production of product in the amount of $220.8 million. The Company will sell product to UT under individual purchase orders, which represent distinct performance obligations. The ultimate cash flows may vary as manufacturing purchase orders are received.
