Sometime between 7/1/13 and 9/30/13 TNKE signed an $800,000 contract to license the technology from PV Enterprises International. This was announced on 11/14/13 via PR and also shows up on the TNKE and PVEI Quarterly Reports (dated 9/30/13).
As you can see on TNKE's next quarterly report (dated 12/31/13), there were two more payments of $6,667 during 10/2013 and 11/2013 towards the license. Then the balance of $779,999 disappears during 12/2013 (was this paid off???): http://www.otcmarkets.com/financialReportViewer?symbol=TNKE&id=116682
PVEI's quarterly report (dated 9/30/13) shows the $800,000 receivable and then shows a $966,945 contract/receivable line in the next quarterly report (dated 12/31/13).
