Analyst · SunTrust Bank
Great, thank you Chuck. Good morning. With me on the call today are founder, Chairman and CEO, John Schnatter; EVP of Global Operations and President PJ Food Service, Tony Thompson; Chief Marketing Officer Andrew Varga, and other members of our senior management team. After our brief financial update, John will have comments about our business and the management team will then be available for Q&A.
Our discussion today will contain forward-looking statements that involve risks and uncertainties relating to future events. Actual events may differ materially from the projections discussed today. Certain factors that can cause actual results to differ materially are outlined in our earnings release and in our Form 10-K.
In addition certain financial measures we use on this call including earnings per share excluding BIBP and free cash flow are expressed on a non-GAAP basis. Our GAAP to non-GAAP results reconciliation can be found in our earnings press release available on the Investor Relations section of our website. This call is being taped and the replay will be available for a limited time on our website and in downloadable podcast format.
As more fully described in our press release beginning in 2011, we no longer have operating income for the BIBP cheese purchasing entity. So we no longer need to report earnings on a pro forma basis, exclusive of BIBP gains or losses. We will continue to show 2010 results excluding BIBP for comparing purposes.
We are in a $0.65 per share and Quarter Four 2011, a 27.5% increase over $0.51 per share in Q4 2010 excluding BIBP. For the full-year 2011, earnings per share were $2.20 representing an increase of 22.2% over $1.80 for the full-year 2010 excluding BIBP. Our fourth quarter 2011 revenues increased 6.8% compared to the fourth quarter of 2010, primarily due to comparable sales of 1.7% for North America and 5.2% for International.
For the full year 2011, revenues increased 8.1% over 2010 primarily due to full year comparable sales of 3.4% for North America and 5.1% for International. The impact of higher commodity costs on PJ Food Service revenues also contributed to the overall revenue increase as did a 6.5% increase in the number of units operating globally on year-over-year basis.
Our unit openings momentum remained strong with 103 net units opened worldwide in the fourth quarter. For the year, we opened 237 net worldwide units. On a business segment basis, operating income for domestic company-owned restaurants increased approximately $400,000 for the fourth quarter compared to 2010 primarily due to increased comp sales of 1.2%.
For the full-year 2011 domestic company-owned restaurant operating income decreased approximately $2.6 million from 2010 levels, primarily due to continued high commodity costs partially offset by positive comp sales of 4.1%. Operating income for our domestic commissary business segment increased $1.7 million for the fourth quarter and $2.2 million for the full year 2011 as compared to the same periods in 2010 excluding BIBP. These increases were primarily due to the higher sales levels and higher number of units previously discussed.
Operating income for our North America franchising segment increased approximately $500,000 for the fourth quarter and $4 million for the full year 2011 as compared to the same periods in 2010 primarily due to comparable sales of 1.8% for the quarter and 3.1% for the year and also increases in the number of franchise restaurants.
The stated royalty rate also increased from 4.75% to 5% at the beginning of 2011. However, the effective royalty rate was fairly consistent between the current and prior years due to incentives earned by our franchises in 2011. Operating results for our international segment improved approximately $1.3 million for the fourth quarter and $4.6 million for the full-year 2011 in comparison to prior year periods, primarily due to an increase in royalty revenue from the previously noted increases in units and comp sales plus continued improvement in the results of our UK quality control center.
Our international segment nearly broke even in 2011 with $165,000 loss and is firmly on track to attain profitability in 2012 as we had previously guided. Our effective tax rate was 31.2% in 2011 and 32.3% in 2010 excluding BIBP.
As we’ve discussed before, our effective tax rate may fluctuate for various reasons including settlement of resolution of specific federal and state issues. We repurchased approximately $15.7 million of stock during the fourth quarter bringing year-to-date share repurchases to approximately $65.3 million in 2011. The company had approximately $69.3 million of remaining share repurchase authorization as of February 14.
Our free cash flow and non-GAAP measure we define as cash flow from operations excluding BIBP, less capital expenditures was $71.7 million for 2011, representing a free cash flow yield of 7.2% based upon 24.6 million average diluted shares outstanding and yesterday’s $40.29 closing market price.
Our net debt position defined as total debt, less cash and cash equivalents was $34.3 million at year end and $18.5 million reduction during the year. We are reaffirming our 2012 earnings per diluted share guidance range of $2.33 to $2.43 which as previously announced which includes a negative $0.11 impact of a one-time marketing incentive contribution and also includes the positive impact of the 53rd week of operations in 2012. We also reaffirm all other guidance provided in our December 20th 2011 press release. And I would like to turn the call over to our Founder, Chairman and CEO, John Schnatter. John?
