Thanks, Randy. For the fourth quarter, the company reported net sales of $430.9 million compared to $227.2 million in the year ago period. The $203.7 million increase in sales primarily resulted from higher selling prices for our finished products and a full-year sales contribution from the Griffin acquisition.
As Randy mentioned, during the fourth quarter as compared to the third quarter of 2011, fat and protein prices declined more than 10% and 12%, respectively, due primarily to lower export demand from European biodiesel and a softening demand for protein meal as a result of cutbacks by poultry producers.
Net income for the 2011 fourth quarter increased to $29.5 million or $0.25 a share on a fully diluted basis as compared to net income of $10 million or $0.12 a share for the 2010 comparable period. As noted in our press release, the $19.5 million increase in net income for the fourth quarter resulted primarily from the acquisition of Griffin Industries, as well as higher selling prices for our finished product. Fourth quarter net income compared to 2011 third quarter was negatively impacted by the decrease in both fat and protein finished product prices, which impacted margins in our non-formula business.
In addition to the decrease in pricing, our aggregate expenses for depreciation, income taxes and SG&A increased by more than $0.04 per share in the 2011 fourth quarter as compared to our prior quarterly average expenses. Depreciation expense increased primarily due to an unusual large number of capital projects being completed and placed into full service in the fourth quarter. Darling's policy is to record a half year of booked depreciation on capitalized products, which resulted in depreciation and expense increasing by $2 million in the fourth quarter of 2011.
These capitalized projects increased our tax bonus depreciation, which in turn, impacted our effective tax rate because it reduced the production credit deduction. This, along with increases in state and foreign income taxes, increased our effective tax rate by $2 million for the fourth quarter.
Approximately $9 million of the $17 million income tax return that you noticed on the balance sheet relates to these book and tax depreciation adjustments. And finally, our SG&A expenses were up approximately $2.5 million related to health benefit accruals and workers comp actuarial true-ups and increased consulting expenses.
At the segment level, Rendering generated net sales of $360.7 million for the fourth quarter as compared to $217 million in the fourth quarter of 2010. Bakery by-product sales contributed $70.2 million the fourth quarter of '11.
Now turning to the results for the full year ended December 31, 2011. Darling reported net sales of $1.79 billion as compared to $724 million during fiscal 2010. The $1 billion increase in sales primarily resulted from higher selling prices for our finished products and from 52 weeks of contribution from the acquisition of Griffin Industries compared to a 2-week contribution in the prior year period.
Net income for 2011 was $169.4 million or $1.47 per share as compared to $44.2 million or $0.53 per share for the 2010 comparable period. The $125.2 million increase in net income for 2011 resulted primarily from higher finished product prices and contributions from the Griffin acquisition.
Interest expense was $37.2 million during 2011 compared to $8.7 million last year, an increase of $28.5 million. This primarily is due to an increase in debt outstanding as a result of the Griffin acquisition in December 2010.
Other expenses was $3.6 million in 2011, a $0.2 million increase over the $3.4 million reported last year. The increase is primarily due to an increase in unused bank fee commitments that more than offset the decrease in costs incurred in the prior year from losses reported due to fires at 2 plant locations and write-off of deferred loan costs due to the termination of the previous credit agreement.
At the segment level, Rendering generated net sales of $1.5 billion in 2011 as compared to $714 million in the comparable 2010 period. The Griffin acquisition accounted for $583.4 million of rendering net sales as a result of a 52-week contribution, and higher finished product prices contributed $210.7 million to the increase. Keep in mind that our Rendering segment includes our used cooking oil removal service and our grease trap services. Bakery segment sales accounted for $296 million of sales for 2011.
As discussed in our third quarter call, we are now separately reporting the company's investment in our joint venture with Valero, as an investment in the unconsolidated sub on both the statement of operations and on our balance sheet. On the balance sheet, we reported an investment of $21.7 million at December 31, 2011, and the statement of operation reports a net loss of $1.6 million for 2011. These losses are largely due to non-capitalized expenses as we proceeded through the construction phase.
Let me provide some additional balance sheet detail now. On December 31, 2011, the company had working capital of $92.4 million, and our working capital ratio was 1.73:1 compared to working capital of $3.8 million and a working capital ratio of 1.2:1 on January 1, 2011. The increase in working capital is primarily due to increases in commodity prices and increase in inventory volumes.
At December 31, 2011, the company had unrestricted cash of $38.9 million, and funds are available under our revolving credit facility of $391.6 million compared to unrestricted cash of $9.2 million and funds available under the facility of $141 million at January 1, 2011.
We voluntarily prepaid $30 million on a term loan during the fourth quarter, and subsequent to yearend, we paid off the remaining $30 million of the term loan B. The only thing that's open now is our $250 million of our debt.
Capital expenditures of $60.2 million were made during 2011 as compared to 24.6 -- $24.7 million in 2010, a significant increase of $35.5 million. The increase is due primarily to capital expenditures by Griffin, which was acquired in December '10, compared to prior year CapEx, which included only 2 weeks of Griffin. I will now turn the call back over to Randy.
