Thank you, John. And good morning, everyone. Last night, we reported second quarter FFO of $0.37 per share. Net income attributable to common stockholders was $0.08 per share for the second quarter. The company's Board of Directors has declared a dividend on this common stock of $0.21 per share for the quarterly period ending September 30, 2013. The dividend will be paid on September 27 to stockholders of record on September 13, 2013.
American Assets had a solid second quarter performance based on steady leasing and increased pricing power due to consistently strong occupancy in retail and office, with retail occupancy at the end of the second quarter increasing by 50 basis points to 96.6%, primarily due to a new lease with U Gym at Waikele Center in Hawaii. Total office portfolio occupancy decreased quarter-over-quarter by approximately 100 basis points, primarily due to 2 tenants leaving, one of which was Skyy Spirits at One Beach Street in San Francisco and the other was a smaller tenant at Torrey Reserve. Skyy Spirits' lease was a below-market lease at a rate less than $30 per square foot. The market rent for that space with unobstructed views of Alcatraz, on the North Waterfront in San Francisco, is somewhere in the 40s. We are looking forward to re-leasing that space. For purposes of our operating model, we have left it vacant for the remainder of the year. All of our other same-store office buildings in our portfolio continue to maintain strong occupancy statistics as shown in the supplemental.
Let's talk about same-store NOI for a moment. Same-store retail NOI for the quarter continue to have very impressive growth at 10.5% on a cash basis and 4.8% on a GAAP basis. This growth reflects not only in place contractual bumps on existing retail tenants, but also the addition of Nordstrom Rack leases at both Carmel Mountain Plaza and Alamo Quarry. H&M at Del Monte Center also opened in late June 2012 and began paying rent at that time. A new lease with Petco at South Bay Marketplace.
Retail leasing spreads are also a testimony to the quality and location of the retail product available for lease, as spreads on 11 comparable retail lease renewals increased at an average of 8.9% on a cash basis and 17.6% on a GAAP basis, as shown in the supplemental. Same-store or office NOI for the quarter increased 4.8% on a cash basis and reflects the strong salesforce.com rent being received at our Landmark property in San Francisco compared with last year's free rent period through May 2012.
On a GAAP basis, same-store office NOI decreased by 1.7%, reflecting the lower occupancy of Lloyd in Portland and One Beach in San Francisco on a year-over-year basis. Office leasing spreads on 12 comparable office lease renewals decreased an average of 3.8% on a cash basis, but it did increase 5.4% on a GAAP basis as shown in the supplemental. The decrease in the office leasing cash basis spreads was mostly attributable to 1 tenant who signed a lease at the top of the market in 2007. Same-store multifamily NOI, which comprises of approximately 6% of our total NOI, increased 31.6% on both the GAAP and cash basis, primarily reflecting continued strong occupancy gains combined with increased rents on a year-over-year basis. Multifamily occupancy remains strong at 97.7% leased overall at the end of the second quarter.
Waikiki Beach Walk, our mixed-use property, which represents approximately 13% of our NOI, continues to outperform with strong same-store growth of 12.2% on a cash basis and 9.5% on a GAAP basis. The Embassy Suites just by itself had 20.5% same-store NOI growth on a year-over-year basis for the second quarter. It really demonstrates the high quality of this asset with the right product in an extremely high barrier to entry location that is favored by tourists. We expect this mixed-use asset to only get better over time.
Turning to our results. 2013 second quarter FFO was $0.37 per diluted share, which was approximately the same as the previous quarter. There was nothing that really stood out other than the following 3 items: One, the expected seasonality of the Embassy Suites Hotel decreased FFO by approximately $0.01 per FFO a share. Secondly, G&A increased slightly to $4.4 million during the quarter. But we continue to focus on an overall run rate of $4.2 million per quarter going forward. And third, during the second quarter, we had nonrecurring income related to a property tax refund at Alamo and a bankruptcy liquidation distribution from borders that combined, netted approximately a little less than $0.01 of nonrecurring income.
Now as we look at our balance sheet and liquidity at the end of the second quarter, we are well positioned to continue to execute on our strategy of selectively acquiring or developing accretive high-quality assets in our core West Coast markets. At the end of the second quarter, we had approximately $291 million in liquidity comprised of $63 million of cash and cash equivalents and $228 million of availability on our line of credit.
At the end of the second quarter, our total capitalization was 36.9% and our net debt to EBITDA was approximately 6.8x. We are focused on keeping our leverage ratio at 45% or less and positioning our balance sheet so we have the ability to approach investment grade market in 2015.
As I've mentioned before, we do have an internal roadmap to approach investment grade debt market in 2015. In order to do so, we recognize that we need to get our secured debt ratio less than 30%. Part of our plan is to refinance our fixed-rate CMBS maturities in 2014 with unsecured debt, subject to economic market conditions at that time, and then approach the investment grade market in 2015 to refinance our fixed-rate CMBS 2015 maturities. We always have several ways to go and are focused on conservative and disciplined balance sheet management. We are not only focused on long-term NAV growth for our shareholders, but also on positive same-store NOI growth on a relative basis, which we believe will ultimately translate into organic FFO growth and increasing shareholder value.
Lastly, we are increasing our full year 2013 guidance to $1.47 to $1.50 per FFO share with the midpoint of $1.485. From our prior guidance of $1.42 to $1.49 per FFO share with a midpoint of $1.45. I should also point out that the $25 million in equity that we raised through the ATM during the second quarter at a premium to our NAV with our weighted average price of $35.09 was dilutive to full year guidance by approximately $0.01 per FFO share. However, as a result of the strength of the portfolio and impressive same-store growth, we are increasing the upper range by an additional $0.01 per FFO share and tightening up the lower range of our guidance as well. The primary driver for the updated guidance is the nonrecurring income for the retail portfolio in the second quarter; the continued out-performance of the mixed-use asset in Waikiki, Hawaii; and higher than anticipated occupancy for our multifamily portfolio.
Our updated 2013 guidance midpoint of $1.485 per FFO share is approximately a 10% growth rate over our 2012 actual of $1.35 per FFO share. And is based on the following 4 assumptions for same-store growth on a cash basis: one, the retail portfolio is now expected to increase by approximately 4%; two, the office portfolio is expected to be flat to slightly down due to the sale of King Street, reduced occupancy at Lloyd and the assumption that the Tax and Treasury Department vacates First & Main in Portland, Oregon, which we factored in to our original underwriting of this property; third, multifamily is now expected to increase 10% due to higher occupancy in the second half of the year versus 2012; and lastly, mixed-use is now expected to increase 10% due to the continued out-performance of the Embassy Suites Hotel in Honolulu, Hawaii. Our guidance excludes any impact from additional acquisitions, dispositions, equity issuances or repurchases or debt refinancings.
We will continue our best to be as transparent as possible and share with you how we are thinking about our quarterly numbers. We are well prepared with a strong balance sheet to capitalize and execute on the opportunities that we believe will present themselves over the coming quarters. Operator, I'll now turn the call over to you for questions.
