Ex, money is fungible and net losses are typically not differentiated by the expenses that cause the accumulated loss.
Also, if there is an accumulated deficit of $1.37 billion that includes a warrant appreciation loss of $0.435 billion, then the majority of the deficit comes from losses in other expense categories, such as R&D and SG&A, equal to a larger amount of $0.935 billion.
Bottom line - losses are losses and accumulate until offset by earnings.
Sorry JC, meant to respond to Ex but got into the wrong thread.
