Thank you, Lenny, and good morning, everyone. First quarter operating EPS from continuing operations of $0.75 was the same as on a GAAP basis, up 27% for the quarter, even with a significantly higher tax rate than last year's first quarter. Our results for the quarter reflect the transformation of our business model from the Jack in the Box brands and the annuity-like cash flows that franchising produces. With positive same-store sales growth at both brands and the benefit of refranchising, we were able to leverage margins and SG&A.
Consolidated restaurant operating margin of 18.3% of sales for the quarter was 130 basis points higher than last year's first quarter results.
Jack in the Box margins improved 200 basis points to 19.1% in Q1. The improvement was due primarily to sales leverage, the benefit of refranchising and lower food and packaging cost. The decrease in food and packaging cost as a percentage of sales resulted from the benefit of price increases and favorable product mix changes, which partially offset commodity inflation of approximately 1.7%.
When we complete our refranchising strategy, we expect to operate roughly 400 company Jack in the Box restaurants, and the brand to ultimately be between 80% and 85% franchised. This leaves us with roughly 60 Jack in the Box restaurants that we have targeted to refranchise by the end of fiscal 2014, including the remainder of the Southeast. As we said last quarter, we estimate our pro forma restaurant operating margin for Jack in the Box brand for fiscal 2013, when excluding the restaurants we refranchised during last year, would have been approximately 17.5%, or about 70 basis points higher than our reported Jack in the Box margins of 16.8% last year.
Our company average unit volumes would have been about 1.66 million versus 1.6 million as reported. Looking forward, we estimate that restaurant operating margin for our Jack in the Box brand should increase by more than 100 basis points beginning in 2015, due to the refranchising of the remaining 60 restaurants we plan to sell by the end of 2014.
Qdoba margins decreased 30 basis points to 16.4% of sales, due primarily to higher maintenance and repair costs and credit card fees, which were partially offset by the benefit of less discounting and higher catering sales. In addition, we had minimal pricing in the quarter versus 2% price last June.
SG&A expenses for the first quarter decreased by $7.5 million. The decrease was due primarily to a $5.3 million decrease in pension expense resulting from higher discount rates and the benefit of other actions we have taken, including the sunsetting of the plan and offering participants early retirement and lump-sum payments. In addition, advertising costs decreased by $2.2 million, resulting primarily from the Jack in the Box refranchising strategy, but were also lower at Qdoba due to changes in the timing of advertising activities.
G&A as a percent of systemwide sales improved by 60 basis points to 3.65% for the quarter as compared to our full year guidance of approximately 3.8%. Our full year guidance does not assume any additional mark-to-market adjustments, which reduced G&A by $1.4 million in the quarter.
In the first quarter, we bought back $77 million worth of stock, or nearly 1.6 million shares, at an average price of $48.80 per share. As a result of an additional $200 million authorized by our Board of Directors last week, we now have $259.7 million remaining under stock buyback authorizations expiring in November of 2015.
As far as commodities are concerned, overall, we expect commodity cost for the full year to increase by approximately 1%. Beef has the potential to be the least predictable, but we currently expect these costs to increase approximately 2% to 3% for the full year. Most of our other major commodities are locked for a good portion of the year, including chicken, cheese and bakery.
Now here's our current thinking on guidance for the balance of the year. We are expecting same-store sales growth at company restaurants in the second quarter of 1.5% to 2.5% for Jack in the Box and 2% to 3% for Qdoba. The only changes made to our full year guidance were, delayed -- we delayed some of our company Qdoba openings to enable us to incorporate the learning from the brand positioning work. As a result, we have reduced our CapEx guidance for the year.
Restaurant operating margin for the full year is now expected to range from approximately 18% to 18.5%, depending on same-store sales and commodity inflation. The increase from our prior guidance reflects our Q1 results. As a reminder, Q4 margins will be negatively impacted by roughly 60 basis points as a result of the minimum wage increase in California that will go into effect in our fiscal fourth quarter. Primarily as a result of our higher margin guidance, operating earnings per share are now expected to range from $2.20 to $2.35 in fiscal 2014 compared to operating earnings per share of $1.82 in fiscal 2013.
In summary, it was a very good quarter, which highlighted the nearly complete transformation of our Jack in the Box business model. You'll see in our 10-Q, that we would expect to file later today or tomorrow, that we've adopted a new segment reporting structure to reflect our shared service model, whereby each brand's results of operations are assessed separately and do not include costs related to certain corporate functions which support both brands.
That concludes our prepared remarks. I'd now like to turn the call over to the operator to open it up for questions. Ana?
