In 2008, the company entered into an agreement with NASA to design, build and demonstrate a new space transportation system under a program called Commercial Orbital Transportation Services ("COTS"), for delivering cargo and supplies to the International Space Station.  Under the agreement, as amended, NASA has agreed to pay the company $288 million in cash milestone payments, partially funding Orbital's project costs which are currently estimated to be approximately $532 million.  The company expects to complete this project in the second half of 2013.

The COTS agreement is accounted for as a best-efforts research and development cost-sharing arrangement.  As such, the amounts funded by NASA are recognized proportionally as an offset to the company's COTS program research and development expenses, including associated general and administrative expenses.  The following table summarizes the COTS program research and development expenses incurred and amounts funded by NASA (in millions):

The company is engaged in a major product development program of a medium-capacity rocket named Antares.  Approximately $4.4 million and $8.1 million of the company's research and development expenses in the second quarter of 2013 and 2012, respectively, and $12.3 million and $19.7 million in the first half of 2013 and 2012, respectively, were attributable to the Antares program.  Since the inception of the Antares program through June 30, 2013, the company has incurred $247.2 million of such costs.
