You can find the article on Yahoo FInance, but, here's an excerpt:
Three of Tilson's four largest current short positions include InterOil Corporation (NYSE: IOC), K12 (NYSE: LRN) and Nokia (NYSE: NOK). Tilson started touting InterOil as a short back in 2010, where he said that he has never had more conviction, and put the stock as his largest bearish position. Tilson notes that after more than a decade of drilling, InterOil has "no proven or even probable reserves, just a lot of hype." Ari Levy of Lakeview Investment Group also has InterOil has a high conviction short (read more about the IFK presentation). Levy believes InterOil made misstatements to investors and agrees the company has no reserves.
******************
As yesterday's article by Treasure Hunter points out -- these are pretty weak arguments. The only thing standing between resources and reserves is the sell-down (next month) and the FID by the Board of Directors of all companies involved (perhaps a few months later).
