As DR stated, Pegatron manufactures the 5C and is paying IDCC royalties on a per unit basis.
The question I was attempting to answer is why has the valuation fallen so low. Of course, a substantial problem is the lack of new licensees. However, I think one reason that the ex-cash valuation is even lower than previous falls is that the current per unit licensees are doing terribly.
Last fall, it was hoped that Pegatron might make up for the falls in Sharp, HTC, and Blackberry. The lower than expected sales of the 5C have hurt that possibility and I think that is extending the fall in valuation.
