If Corvisa does close, I suspect the company goes private at shareholder loss.
"Net loss from continuing operations $ (6,971 ) $ (2,376
"As of March 31, 2015, the Company contributed approximately $25.6 million of the allotted $30 million to Corvisa.

"
The loss was $7 million and total revenue actually declined from the previous quarter.
