In the first nine months of 2016, we wrote off the carrying value of certain excess inventory resulting in a charge of $556 million, net of existing reserves of $260 million. In addition, we accrued $31 million of related disposal costs. See Note 3. "Impairment and Restructuring Charges" for further discussion. We have been disposing of the excess inventory, and were substantially completed by the end of the third quarter of 2016.
