Thank you, Dirk. The following remarks are related to our reported operating performance for the quarter ended December 31, 2011. To present comparative revenue results between 2010 and 2011, we are utilizing pro form revenue schedules. The company's pro forma revenues include Scient'x for all period of 2010 and do not include IMC for any period of 2010. The press release issued today provides our geographic sales segment performance on both the GAAP and a pro forma basis. On this call I will be discussing the actual performance of our business on a GAAP basis, and if applicable, referencing pro forma comparisons. Beginning with the first quarter of 2012 we will no longer need to use pro forma comparisons.
Dirk has already covered U.S. and international sales for both the fourth quarter and full year, so I won't repeat those numbers. I will however echo Dirk’s comments that overall we are pleased with our revenue performance in spite of the difficult environment, and recognize our need to improve our operating performance. Gross profit for Q4 2011 was $24.9 million, or 50.3% of revenue, compared to $31.5 million or 68.4% of revenue in Q4 of 2010.
Gross profit and gross margin in the fourth quarter were impacted by one time charges totaling $5.5 million, primarily related to inventory write-offs and adjustments. After netting out this impact, the underlying gross margin was approximately 61.4%. As compared to the prior period where a considerable favorability was attributable to high plant throughput, we experienced more moderate absorption of manufacturing costs in the current quarter. Favorable gross margins from our business in Japan was more than offset with increases in milestones and modest price impacts.
Mixing gross margin associated with our biologics business also contributed an 80 basis point decline in margin. U.S. gross margins for Q4 2011 were 57.2% versus 78.1% reported in the Q4 2010. After adjusting for inventory write-offs and the equalization of manufacturing absorption, the adjusted gross margin for the fourth quarter was 71.6%. Increased milestone payments represent 140 basis points. Price and biologix mix were an additional 320 basis points. The remaining variances are attributable to other manufacturing activities.
International gross margin was 36.9% for the fourth quarter of 2011, versus 46% in the fourth quarter of 2010. After adding back the onetime adjustments the overall gross margin would have been 53.4%. When comparing the gross margin of the fourth quarter of 2010, we have seen improvements directly attributable to the continued success of Japan, which enjoy that comfortably higher gross margin than the other regions of the world. As well as modest mix and cost improvements. In Q4 we invested significant resources to improve our inventory control and processes. In 2012, we anticipate achieving greater visibility and predictability with respect to our forecasted gross margins, and we believe that the level of write-offs experienced in 2011 should not repeat itself in 2012.
As we announced on January 5, 2012, the company reached a global settlement agreement with Cross Medical Products, a subsidiary of Biomet, regarding a license agreement dispute and a patent infringement dispute. As part of the settlement Alphatec Spine has agreed to pay Cross Medical $18 million. And we made an initial payment of $5 million in January of 2012. In addition to the initial payment, we will make 13 payments of $1 million per quarter thereafter, starting in August of 2012. The company has expensed $9.8 million in the fourth quarter of 2011, which was charged to operating expenses as a legal settlement adjustment.
Of the remaining $8.2 million, $8 million will be recorded as a licensed intangible asset to be amortized over the next 7 quarters in 2012 and 2013. Plus an associated imputed interest of $200,000. A non-cash charge of approximately $1.1 million per quarter of intangible asset amortization will be reflected in cost of goods sold in 2012. However, these amounts will be added back as part of our adjusted EBITDA calculation. Total operating expenses for Q4 2011, were $41.4 million, excluding the $9.8 million settlement expense I mentioned previously, operating expenses were $31.6 million, a decrease of $1.6 million compared to prior year of $33.2 million, and a sequential decline of $1.1 million from the $32.6 million reported in Q3 of 2011.
The sequential improvement reflects the positive benefit from the activities undertaken over this past summer. In addition to aggressively managing our overall operating expense profile. After factoring in the additional onetime expense incurred in Q4 of 2011, our operating expenses were $30.5 million compared to Q4 of 2010. GAAP net loss for the fourth quarter of 2011 was $16 million or $0.18 per share, compared with a net loss of $2.9 million or $0.03 per share for the fourth quarter of 2010. Non-GAAP net loss for the fourth quarter of 2011 was $5.2 million or $0.06 per share compared to a non-GAAP net loss of $1.5 million or $0.02 per share reported for the fourth quarter of 2010.
Non-GAAP net loss for the fourth quarter of 2011, includes adjustments of the $9.8 million related to the Cross Medical settlement as well as the amortization of intangible assets and restructuring expenses. Adjusted EBITDA was a negative $1.2 million in the fourth quarter of 2011, a decrease of $5.6 million compared to the $4.4 million reported for Q4 of 2010. The decline in adjusted EBITDA is due to reduced gross profit noted above, compared to Q4 2010, offset by lower operating expenses. Adjusted EBITDA represents net income or loss excluding the effect of interest taxes, depreciation, amortization, stock-based compensation and other nonrecurring items such as restructuring expense, IP R&D and transaction-related expenses.
Cash and cash equivalents were $20.7 million at December 31, 2011, which is a $1.5 million decrease from the $22.1 million reported at September 30 of 2011. For the fourth quarter, the business operations generated $2 million of cash flow, which was offset by a further $3.5 million of additional debt repayments associated with our working capital line of credit. Cash and cash equivalents at the end of Q4 2011, reflects a $2.5 million decrease from the $23.2 million at December 31, 2010. Excluding debt repayments of $5 million, our business generated $2.5 million of cash flow for the year.
The debt repayments associated with our working capital line of credit, were a function of a covenant violation associated with calculated adjusted EBITDA. Our bankers waived the fourth quarter violation and in January restored $2.5 million of the repayments. The remaining $2.5 million in repayments will be used for reduction in our overall credit facility and will reduce the total amount of debt owed by the company. We remain committed to generating cash flow and improving our level of profitability in 2012 in order to support the additional financial obligation of the Biomet settlement.
As of December 31, 2011, our net inventory position was $45.9 million, a decrease of $2.9 million versus Q3 of 2011. Our net accounts receivable at the end of Q4 2011 were $41.7 million, an increase of $1.9 million or 4.8% as compared to Q3 of 2011. Our days sales outstanding were in line with the previous quarter and represented a solid performance given our geographic mix of revenues. As we transition into 2012, our clear focus remains on improving our global gross margin and operating expenses profile to ensure that business generates an operating profit and an ability to generate superior cash flow to meet our financial obligations and to sustain the growth of the business.
Our financial guidance for 2012 is as follows. For full year 2012, annual revenue guidance will be in the range $204 million to $209 million, growth of 3% and 6% respectively. We anticipate our gross margin in 2011 to be in the range starting from the low 60s in Q1 and improving sequentially through the rest of the year, as we focus on our major initiatives. Adjusted EBITDA guidance will be in the range of $23 million to $27 million, or 11% to 13% of sales. We anticipate generating positive cash flow for the full year of 2012, while still servicing our debt and settlement obligations.
With several new products recently introduced and transitioning to full commercial release the revenue contributions that we expect from these new products will accrue towards the second half of 2012. In addition the company's revenue guidance range includes only modest contributions from PureGen, our Osteoprogenitor Cell Allograft. Now I would like to turn the call back to Dirk.
