In a new filing with the SEC, media house ZeniMax, owner of Bethesda Softworks, revealed that the company had raised $105 million USD in order to buy id Software. The company noted that it raised the money in “convertible notes and promissory notes issued in connection with the acquisition of substantially all of the assets of Id Software, Inc.”. We don’t know exactly what Promissory Notes are, but we now have an idea what ZeniMax paid for id Software: around $100 million. The company did not reveal the price, but one can only think that it’s north of $100m, as ZeniMax isn’t exactly cash strapped (at least if you count the success of Fallout).
