Thanks, Marcel. And good morning.
Before I get to the numbers, I want to address the difficulty in comparing our operating results for this quarter and the remainder of this year to same periods for 2014. Prior to our listing on the New York Stock Exchange in February, our financial statements were carved out from our former parent's consolidated financial statements and reflect significant assumptions and allocations. These include allocations of corporate overhead costs, certain corporate and shared functions, interest expense and income taxes. In addition, significant costs were incurred in connection with the separation and listing, and we have incurred and will incur onetime costs transitioning to an independent publicly traded company.
During 2014, we sold 55 hotels, 52 of which are reflected in our discontinued operations. There have also been reclassifications of revenue and expense line items to other categories. These reclassifications resulted from the 11th edition changes to the uniform system of accounts, which is the financial reporting standard followed by the lodging industry, and other reclassifications detailed in our 10-Q which will be filed later today. In other words, this is going to be a bit of an apples-to-oranges comparison this year. We will do our best this quarter and throughout the year to clarify these items and their impact.
As a reminder, our first quarter same-property hotel results include all hotels owned as of March 31, 2015, except for the 2 hotels under development. We have included all properties under renovation, as they remained open during the quarter, but removed a guarantee payment from 1 hotel to better provide a clear picture of hotel-level operating performance.
RevPAR growth in our 46-same-property portfolio increased 2.6%, which as Marcel mentioned, was primarily impacted by renovation projects underway at 3 of our largest hotels: the Marriott San Francisco Airport Waterfront, the Hyatt Regency Santa Clara and the Aston Waikiki Resort Beach.
Our portfolio mix is approximately 70% transient and 30% group. 2015 group booking revenue pace is ahead of same time last year by roughly 5%, largely driven by increases in projected rate, as total group room nights are down slightly due largely to weakness in Texas markets. Our strong-performing markets in terms of 2015 group pace include Atlanta, Santa Clara and New Orleans.
In regard to 2016, it is still too early in the booking window. However, total booking revenue pace for 2016 is up over 5%, as compared to the same period in 2014, looking towards 2015.
As detailed in our press release, we have categorized our portfolio by geographical region according to STR. Our 3 hotels under renovation in the first quarter are in the Pacific region. Excluding this region, our portfolio RevPAR growth was 5.3%, illustrating strong performance throughout the portfolio. The overall Pacific region continues to show robust growth, and we look forward to reaping the benefits of the substantial renovations at our most significant assets in the region after the completion of these projects.
For the quarter, top-performing RevPAR markets in our portfolio include Boston, downtown Chicago, Key West, Phoenix, Pittsburgh and St. Louis, which all had double-digit RevPAR growths. Our weakest markets included Waikiki and San Francisco due to the renovation disruption, as well as Houston, which Marcel discussed earlier.
We are pleased with our strong flow-through and margin expansion, with hotel EBITDA margin of 30.7%, an increase of 112 basis points for the quarter. We had outstanding expense control during the quarter, with hotel-level expenses increasing just 1.9% despite a substantial increase in real estate taxes related to our 2013 acquisitions. These increases were underwritten with each acquisition and are part of our 2015 guidance, but are due to both tax reassessments at the time of acquisition as well as the expiration of several real estate tax abatements. We continue to aggressively pursue valuation reassessments in multiple jurisdictions and are optimistic for potential reductions.
A quick update on the 2 Napa hotel earthquake insurance claims. As we have previously outlined, the Marriott Napa Valley hotel sustained limited damage and fully reopened in October 2014. The Andaz Napa, which was substantially closed during the entire fourth quarter of last year, partially reopened in late December and fully reopened in January of this year. We estimate $2.4 million in damage at the Marriott and $7.2 million in damage at the Andaz, all of which we expect will be reimbursed by property insurance proceeds, less a small deductible.
Through the end of the first quarter, we received business interruption insurance proceeds of $3.7 million, which is included in other income on our operating statement, net of hotel-related expenses. We are not including these BI insurance proceeds related to 2014 lost income in either adjusted EBITDA or adjusted FFO for 2015.
Corporate and general administrative expenses for the quarter totaled $7 million, which includes $1.7 million of amortization of share-based compensation. In addition, we incurred $25 million of onetime expenses related to our separation from our prior parent, our listing on the New York Stock Exchange, the completion of our modified Dutch tender offer and startup costs. The recurring cash G&A expense for the quarter was $5.3 million, which is in line with our annual cash G&A expense of between $20 million and $22 million included in our 2015 guidance.
Adjusted EBITDA for the quarter was $64.7 million, up 15.3% year-over-year. Adjusted FFO was $50.8 million, an increase of 23.7%, and adjusted FFO per share was $0.45.
Now let's turn to our capital market activities during the quarter and our balance sheet.
Concurrently with our listing, we announced a modified Dutch tender offer for up to 20 -- for up to $125 million of our common stock at a price between $19 and $21. The tender was undersubscribed. And on March 5, we repurchased approximately 1.8 million shares at $21 for a total of approximately $37 million.
At the end of the quarter, we had $238 million of cash. Our total debt was just under $1.2 billion. And there was no outstanding balance on our $400 million line of credit, which closed effective with our listing in February. This quarter, we also extended the mortgage on our Marriott Griffin Gate property and repaid the $26 million mortgage on our Andaz San Diego hotel.
Our net debt-to-EBITDA ratio, as defined in our line-of-credit agreement, was 3.7x, which translates into a current borrowing rate on the line of LIBOR plus 175 basis points. The weighted average interest rate on our outstanding debt is 4%, and we have 19 unencumbered hotels. Included in our press release are additional details on our debt profile, including interest rate, outstanding balance and maturity date by loan. We have a very manageable debt maturity profile with 1 loan maturing later this year and 5 loans maturing next year. We are evaluating a number of options to address each loan with the idea of extending our maturity profile, lowering our cost of capital and further unencumbering our portfolio.
We have substantial liquidity and financial flexibility with which to execute our business plan. As discussed, we continue to pursue acquisition opportunities, but we'll also continue to evaluate other alternatives to best utilize our excess cash.
I want to thank you again for joining our inaugural earnings call as an independent public company. We look forward to continuing our dialogue in the future and have concluded our prepared remarks.
Operator, we would be happy to answer questions now.
