Due to related parties (primarily accrued interest on the Solar Bonds and Convertible Senior notes, included in accrued and other current liabilities)	$	5,136

The related party transactions were primarily issuances and maturities of Solar Bonds held by SpaceX, our Chief Executive Officer, SolarCity’s Chief Executive Officer, and SolarCity’s Chief Technology Officer and issuances of convertible senior notes to an entity affiliated with our Chief Executive Officer and SolarCity’s Chief Executive Officer. SpaceX is considered a related party because our Chief Executive Officer is the Chief Executive Officer, Chief Technology Officer, Chairman, and a significant stockholder of SpaceX.

As of December 31, 2016, SpaceX held $90.0 million in aggregate principal amount of 4.40% Solar Bonds due in March 2017 and $75.0 million in aggregate principal amount of 4.40% Solar Bonds due in June 2017.
