Mr Musk’s financial ties to SolarCity are also complicated. SpaceX, his private space company, has invested $165m in SolarCity’s bonds. Along with Lyndon Rive, he has also personally invested $13m in the company’s convertible debt. And Mr Musk has pledged 4m of his 22m SolarCity shares as collateral against personal borrowings from Morgan Stanley.
A steep fall in SolarCity’s share price this year has increased the possibility he might have to put up more collateral. At the same time, the solar company’s financial position has increased the risk from its borrowings. In a note to clients before Tesla’s buyout proposal was announced, Goldman Sachs said the company might be at risk of breaching a covenant on a $399m revolving credit facility this quarter. The bank added, however, that it did not expect such an outcome, and that SolarCity should not face the same risk in future quarters.
