Thank you, Scott. Our fourth quarter net loss was $17 million or $1.80 per diluted share in 2013. This included a noncash, after-tax, fixed-asset impairment charge of $17.3 million. Excluding this charge, adjusted net income in the fourth quarter of 2013 was $319,000, or $0.03 per diluted share, compared to net income of $4.5 million or $0.48 per diluted share, in the fourth quarter of 2012.
Water Transmission sales decreased 51% to $43 million in the fourth quarter of 2013 from $88 million in the fourth quarter of 2012. Water Transmission gross profit as a percent of sales decreased to 16.4% in the fourth quarter of 2013 from 19.9% in the fourth quarter of 2012.
Tubular Products sales increased 51% to $72 million in the fourth quarter of 2013 from $48 million in the fourth quarter of 2012. Volume increased 64% while average selling prices decreased 8%. We sold 66,100 tons in the fourth quarter of 2013 as compared to 40,200 tons in the fourth quarter of 2012. Tubular Products was breakeven for gross profit as a percent of sales in the fourth quarter of 2013 compared to a negative 6.3% for gross profit as a percent of sales in the fourth quarter of 2012.
Total company inventories remained relatively the same in the fourth quarter from the third quarter of 2013.
Moving on to the full year results. Our net loss was $923,000 or $0.10 per diluted share. This included the noncash, after-tax, fixed-asset impairment charge of $17.3 million. Excluding this charge, adjusted net income was $16.4 million, or $1.72 per diluted share, in 2013 compared to net income of $16.2 million or $1.72 per diluted share in 2012.
Water Transmission sales decreased to $226 million in 2013 from $269 million in 2012. Water Transmission gross profit as a percent of sales increased to 20.7% in 2013 from 16.7% in 2012. The decrease in sales was due to continued weakness in municipal markets. The increase in gross profits and gross profit as a percent of sales was driven by a favorable product mix, including the production of Lake Texoma, the largest project in our history, as well as cost reduction initiatives. These initiatives have improved quality, reduced overhead costs and reduced man hours per ton.
Tubular Products sales decreased 2.4% to $249 million in 2013 from $255 million in 2012. Selling prices decreased 10% while volume increased 9%. We sold 224,300 tons in 2013 compared to 206,200 tons in 2012. Tubular Products gross profit as a percent of sales was 2.2% in 2013 compared to 4.4% in 2012. Our energy product comprised approximately 78% of Tubular Product sales in 2013 compared to 74% in 2012.
Gross profit and gross profit as a percent of sales was negatively impacted by the increased competition from imports, which exerted significant downward pressure on selling prices and volume. In addition, gross profit was negatively impacted by $4.9 million in lower of cost or market inventory adjustments. This was partially offset by cost reduction initiatives successfully implemented at our Atchison facility, which is important as we complete our capacity expansion investment projects at Atchison. The investment projects completed to date have helped increase our 2013 Atchison line pipe shipments by about 50% over the 2012 shipments.
Selling, general and administrative costs decreased to $24.2 million in 2013 compared to $28.6 million in 2012. These decreases covered a wide range of general and administrative cost categories as part of our total company efforts to reduce overhead and administrative costs.
We recorded a $27.5 million fixed-asset impairment charge in 2013, which was $17.3 million after tax. In conjunction with the preparation of our year-end financial statement, we determined that an impairment-triggering event had occurred for the assets at our Bossier City, Louisiana facility due to increased competition in the OCTG market and pricing and volume pressures from imported pipes.
Interest expense was $4 million in 2013 and $5.6 million in 2012. The decrease was the result of lower average interest rates and decreased amortization of deferred financing costs, partially offset by higher average borrowings.
Our effective tax benefit rate was 69.7% in 2013, and our effective tax provision rate was 25.4% in 2012. During 2013, we performed a research and development tax credit study, which resulted in a net tax benefit of $900,000.
In 2013, the company generated $20.1 million in cash from operations to support the growth of the business mainly through our income, excluding the impairment charge, and decreases in inventories and costs and estimated earnings in excess of billings on uncompleted contracts. These were partially offset by an increase in accounts receivable and decreases in accrued liabilities.
Depreciation was $13.3 million in 2013 and $16.3 million in 2012.
Inventory decreased $3 million in 2013 from 2012. This was primarily due to a decrease in Water Transmission coil inventory with the decrease in production. This was partially offset by an increase in inventory due to the Permalok acquisition on December 30.
Capital expenditures were $28.5 million in 2013 primarily for planned capacity expansion in our Saginaw, Texas water transmission facility and our Atchison, Kansas line pipe facility. The remainder was for ongoing maintenance capital expenditures.
Another large investing outflow was the acquisition of Permalok Corporation on December 30 for $15.7 million in cash. We paid this through borrowings on our revolving credit agreement. Our balance on the credit agreement was $87.9 million at the end of 2013.
Now I'll turn it over to Scott for an update on our business.
