(b) Net revenues of "Others" includes revenues from sales of Subsystems, assembly services and other revenues.
(c) Operating income (loss) of "Others" includes items such as unused capacity charges, impairment, restructuring charges and other related closure costs, phase out and start-up costs, and other unallocated expenses such as: strategic or special research and development programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of the Subsystems and Other Products Group. "Others" includes $2 million, $24 million and $16 million of unused capacity charges in the second and first quarters of 2013 and second quarter of 2012, respectively; and $43 million, $101 million and $56 million of impairment, restructuring charges and other related closure costs in the second and first quarters of 2013 and second quarter of 2012, respectively.
Sense & Power and Automotive Products (SPA) second quarter net revenues increased 7.3% sequentially, mainly driven by Industrial and Power products and Automotive. SPA revenues increased 4.6% compared to the year-ago quarter driven by MEMS. SPA operating margin was 3.5% in the 2013 second quarter compared to 5.1% and 8.3% in the prior and year-ago quarter, respectively, with the decrease principally driven by resources deployed from ST-Ericsson to strengthen R&D activities and price pressure within the Analog, MEMS and Sensors (AMS) group.
Embedded Processing Solutions (EPS) second quarter net revenues decreased 5.0% and 16.0% on a sequential and year-over-year basis, respectively, due to a significant decrease in ST-Ericsson sales and to a lesser extent, Digital Convergence (DCG). EPS segment operating margin improved to negative 12.8% in the 2013 second quarter, from negative 24.2% and negative 23.7% in the prior and year-ago quarter, respectively, mainly due to a significant reduction in expenses.
Cash Flow and Balance Sheet Highlights
Free cash flow* was negative $134 million in the second quarter, principally reflecting anticipated cash resources to fund ST-Ericsson, compared to negative $65 million in the prior quarter.
Capital expenditure payments, net of proceeds from sales, were $121 million during the second quarter of 2013 compared to $111 million in the prior quarter.
Inventory increased by $30 million to $1.34 billion at quarter end. Inventory in the second quarter of 2013 was at 4.1 turns or 88 days, substantially flat compared to the prior quarter.

First Half 2013 Results
Net revenues decreased 2.6% to $4.05 billion from $4.16 billion in the year-ago period mainly reflecting lower ST-Ericsson sales. Net revenues for the first half of 2013, excluding the Wireless product line, increased 2.5% to $3.62 billion.
Gross margin was 32.1% of net revenues, compared to 32.0% of net revenues for the 2012 first half. The first half 2013 gross margin was impacted by unsaturation charges of $26 million compared to $87 million in the year-ago period. Net loss, as reported, was $322 million in the first half of 2013, or $(0.36) per share, compared to a net loss of $252 million, or $(0.28) per share in the first half of 2012. On an adjusted basis, net of related taxes, ST reported a non-U.S. GAAP net loss per share of $(0.19) excluding impairment, restructuring charges and one-time items in the first half of 2013, the same as in the first half of 2012.*
