Thanks, John. Yesterday, Tyler Technologies reported its results for the fourth quarter ended December 31st, 2011. You've seen the press release, I'm going to comment on some of the key factors in the quarter then move on to John's comments on the current quarter and our outlook for 2012. Revenues for the fourth quarter were $82.1 million, a new quarterly high, up 13.3% compared to $72.4 million for the fourth quarter of 2010. Organic revenue growth was 9.7% this quarter led by increases on our recurring revenues for maintenance and subscriptions as well as growth in our software license revenue for the first time since the fourth quarter of 2009.
Our acquisition of Windsor Management Group in October accounted for revenues of $2.6 million in the fourth quarter or 3.6 percentage points of the growth. Software license revenues grew 16.1% from last year's fourth quarter and were the highest since the fourth quarter of 2009. Organic growth in licenses was 9.9%. And Windsor added 6.2% of growth in licenses.
Subscriptions continue to be our fastest-growing revenue line and grew 43.6%, virtually all organic. In the fourth quarter, we added 9 new subscription-based arrangements and converted 12 existing installed clients compared to a total of 11 new arrangements and 16 conversions in the fourth quarter of 2010. The subscription lines also includes a growing revenue stream from transaction-based revenues such as e-filing in the courts and online payments. In the fourth quarter, these revenues totaled $2 million up from $1.3 million in the fourth quarter of last year. Software services revenues increased by 7.2% of which 4.5% was organic and 2.7% resulted from the Windsor acquisition.
Organic growth was primarily driven by increased contract signings during the year. Maintenance revenue growth was 13.5% of which 8.6% was from organic growth due to a combination of new revenues associated with license sales in the past year and annual rate increases for existing clients. Our maintenance revenue growth rate has been reduced somewhat by the effect of existing installed clients converting to our hosted offerings, which results in a loss of maintenance revenue offset by a larger increase in subscription revenue. The acquisition of Windsor contributed 4.9% to the maintenance growth in the fourth quarter. Together, recurring revenues from subscriptions and maintenance comprised 58.3% of our total revenues from the fourth quarter and grew 18.1% year-over-year.
Appraisal services revenue decreased 8.0% in the fourth quarter primarily due to the wind down of activity on several revaluations of contracts that began in late 2009 and mid-2010, including a number of Indiana counties in a major revaluation project in Allegheny County, Pennsylvania.
For the fourth quarter of 2011, our blended gross margin increased 250 basis points to 47.5%, which represents our highest quarterly gross margin ever. Last year's fourth quarter gross margin was 45%. Gross margin for our software licenses increased with a higher level of license revenues and the blended software services maintenance and subscriptions margin increased 240 basis points, reflecting the high degree of leverage in the incremental recurring revenues.
SG&A expense was 25.8% of total revenue compared to 23.7% in last year's fourth quarter. The increase in SG&A was mainly attributable to higher incentive compensation accruals in the fourth quarter of 2011 compared to the same quarter in 2010. For the 2011 full year, SG&A expense as a percentage of revenue was 24.5% compared to 24.1% for 2010. Non-cash stock compensation expense was $1.7 million in the fourth quarter of 2011 compared to $1.5 million in the fourth quarter of 2010. $222,000 was included in cost of revenues and $1.5 million was included in SG&A expense.
Net research and development expense decreased 24.3% in the quarter to $2.6 million compared to $3.5 million for the same period last year. Total gross R&D expense before the effect of Microsoft reimbursements was $4.8 million in the fourth quarter of 2011, compared to $4.7 million in the fourth quarter of 2010. R&D expense was offset by cost reimbursement recognized under our agreement with Microsoft of $2.2 million in the fourth quarter of 2011 and $1.3 million in the fourth quarter of 2010.
For the full year of 2011, gross R&D expense related to the Microsoft Dynamics project was approximately $8.1 million, which was offset by total reimbursement of $3.5 million for a net expense for the year of $4.6 million. For 2010, gross Dynamics R&D expense was $8.4 million, offset by reimbursement of $5.1 million for net expense of $3.3 million. We currently expect additional R&D reimbursement offsets of approximately $1 million in 2012. Although the timing of the reimbursement is subject to change, we currently expect that all to be recorded in the third quarter of 2012.
Operating income for Q4 increased 28% to $14.3 million from $11.2 million last year. And our operating margin is 17.4% equaled our highest quarterly level. Net income for the quarter was $8.7 million or $0.27 per diluted share compared to net income of $7.2 million or $0.21 per diluted share in the fourth quarter of 2010.
The fully diluted share count declined in the fourth quarter by approximately 1.9 million shares compared to last year as a result of our stock repurchases.
Our effective tax rate for the fourth quarter was 35.6% and for the year was 37.5%.
During the fourth quarter, we repurchased 53,000 shares of our common stocks for approximately $1.3 million at an average cost of $24.77 per share. As of December 30 2011, we have 30 million common shares outstanding and authorizations to repurchase up to a total of 1.7 million additional shares. For the full year of 2011, we repurchased 3 million shares of our stock at an average cost of $23.90, for a total cost of $71.8 million, which represents approximately 9.3% of the shares outstanding at the beginning of 2011.
Free cash flow for the fourth quarter was $9.0 million compared to $7.4 million for the same period in 2010. For the full year, our free cash flow was $44.2 million in 2011 up 45% from $30.4 million in 2010. Excluding real estate CapEx, our free cash flow was $50.8 million up 60.1% from $31.7 million for 2010. The increase in free cash flow reflects improved receivable collections, higher deferred revenue collections from maintenance and other recurring revenues and lower cash payments for taxes and incentive compensation compared to 2010.
Receivables continue to perform well. Day-of-sales outstanding and accounts receivable was 99 days at December 31, 2011. An improvement of 3 days compared to 102 days at December 31 2010. This is up from 88 days at September 30 as billing seasonally peaked in June and December with a high level of maintenance billings followed by collections in the subsequent quarter.
Our backlog at December 31, 2011 reached our highest level ever at $339.8 million up to 20.7% compared to $281.4 million at December 31, 2010. Backlog related to our software business which excludes backlog from appraisal services contracts was $319.9 million in the current quarter, a 28.9% increase compared to $248.2 million a year ago. Appraisal services backlog was $19.9 million at December 31, 2011 compared to $33.2 million at December 31, 2010. Backlog at December 31, 2011 included approximately $110.3 million of maintenance compared to about $92.6 million a year ago.
Our Q4 bookings were up 24% over Q4 of 2010 and for the full year of 2011, bookings rose 9.2%. With more of our backlog comprised of multi-year subscription agreements as well as certain software contracts that will be multi-year implementations, the timing of the recognition of backlog has lengthened. Approximately 67% of our December 2011 backlog is expected to be recognized during the next 12 months compared to 70% of our December 2010 backlog.
On the balance sheet, we ended the fourth quarter with $3.3 million in cash and investments and $60.7 million in outstanding borrowings under our $150 million revolving credit facility. At December 31, we had $81 million of availability under the credit agreement. The average interest rate on our borrowings in the quarter was 3.3%.
During the fourth quarter, we completed the acquisition of Windsor Management Group. The purchase price was $23.8 million. After netting acquired cash of $7.4 million, we borrowed approximately $16.4 million on a revolver to fund the net cash purchase price. Windsor Management Group contributed $2.6 million in revenues during the fourth quarter. In the first quarter of 2012, we completed the acquisition of Akanda. The purchase price was $2.9 million. And we did not expect this acquisition to have a material impact on revenues or earnings.
Our headcount grew by 80 to 2,091 employees at year-end compared to 2,011 at the end of the third quarter of which 64 were added as a result of the Windsor acquisition. Now, I'd like to turn the call back over to John for his comments.
