Thank you, Steve, and good morning, everyone. As Steve mentioned, we had another good quarter. While we experienced some headwinds from rising interest rates, our core business performed well. Third quarter comparable FFO as adjusted was $0.81 per share compared to $0.71 for last year's third quarter, an increase of $0.10 or 14.1%. The increase was driven primarily by rent commencement on new office and retail leases, the continued recovery of our variable businesses and an adjustment for prior period real estate tax accruals at the mark, partially offset by higher net interest expense from increased rates on our variable rate debt. We provided a quarter-over-quarter bridge in our earnings release on Page 3 and in our financial supplement on Page 6.
Notwithstanding additional interest expense from rising rates on our variable debt will result in lower comparable FFO per share growth for 2022 than we anticipate earlier in the year, we do still expect the comparable FFO per share will be up year-over-year. The additional interest expense from rising rates will have a greater impact next year as the higher rates impact our variable rate debt cost for a full year. We have partially mitigated the impact of this due to the significant amount of hedging we did this quarter, as Steve just covered.
Company-wide, same-store cash NOI for the third quarter increased by 13.8% over the prior year's third quarter. Excluding the accrual adjustments related to the market real estate taxes, the increase would have been still solid 3.4%. Our retail same-store cash NOI was up a very strong 7.7%, primarily due to the rent commencement of several important leases. Our overall office business was up 15% compared to the prior year's third quarter, also benefited by the Mart adjustment, while our New York Office business was down 1.3%, largely due to nonrenewing lower rent tenants at PENN 1 in order to bring higher-paying tenants post redevelopment.
Now turning to the leasing markets. Amidst the backdrop of economic uncertainty, the New York Class A office market remains resilient. Stimulated by the city's tight labor market, our office use job employment is now above pre-pandemic levels at $1.5 million. Leasing activity in Manhattan continued its rebound through the third quarter with volume surpassing pre-pandemic averages. Year-to-date, market-wide leasing activity stands at 24 million square feet, 50% above where we were at this time last year, including 9.3 million square feet this quarter. Deal volume during the quarter was led by 16 headquarters leases signed in excess of 100,000 square feet, reinforcing the large tenants are committed to New York and are signing long-term commitments.
As we enter the fourth quarter, though, caution is the word of the day. There is increasing uncertainty in the world and tenants are acting accordingly. As businesses continue to reassess their space requirements, the bifurcation between high-quality and commodity product is growing. Tenant preference remains strong for best-in-class, newly developed or redeveloped buildings with modern amenities in collaboration spaces and being on top of transportation is critical. Most companies believe the highest quality work experience is key to both incentivizing employees to come back to the office and also for attracting new talent. Our portfolio consists largely of these types of assets, positioning us well to continue to capture tenant demand.
During the third quarter, our office leasing team completed 42 transactions comprising 388,000 square feet across New York, Chicago and San Francisco. In New York, our average starting rents were very strong $89 per square foot, reflecting the breadth of our high-quality portfolio. Our overall leasing pipeline in New York remains strong with approximately 1.5 million square feet of leases in advanced negotiation and proposal stages.
Now turning to Chicago. At theMART, we leased 67,000 square feet in 19 transactions this quarter and a 50-50 mix of office and showroom activity. While the market in Chicago remains challenged, we have seen a pickup in proposal during the quarter. As expected, our trade show business has rebounded nicely in 2022, though not back to pre-pandemic levels yet, with NOI up $12.2 million through 3 quarters versus last year. In San Francisco, at 555 California Street, where we're full except for the [ cube ], we leased 154,000 square feet during the quarter, including a large renewal of Morgan Stanley for its 132,000 square feet and a 21,000 square-foot expansion and renewal with Centerview Partners. Our starting rents were very strong, once again, generating a 12% positive cash mark-to-market. 555 California continues to be the premier real estate asset in San Francisco, particularly for financial tenants as evidenced by these leases.
Retail leasing results were fairly modest for the quarter, with 1 renewal transaction significantly skewing reported GAAP and cash mark-to-market. The bulk of the leasing activity incurred in the redeveloped Long Island Railroad Concourse, where you're seeing very good activity with strong rents. More broadly, with the rebound in tourism and daily workers, we're continuing to see more retailers search for new store locations. However, retailer concerns about inflation in the economy are resulting in them to being more cautious about committing to new leases. This will change as the economic environment stabilizes.
Finally, let me spend a minute on sustainability where we continue to be a leader. Vornado was once again selected as a global and regional sector leader, or diversify the office and retail REITs and Global Real Estate Sustainability Benchmark, or GRESB survey, ranking #1 in the USA in our group and #3 out of all 112 publicly listed real estate companies in the Americas that responded to GRESB. In addition, we once again earned GRESB's 5-star rating, received the Green Star distinction for the tenth time and scored an A for our ESG public reporting and for our score. This area is increasingly important to our tenants and other stakeholders as well and is a differentiator for our portfolio in the market.
Turning to the capital markets now. Overall, the heightened market volatility and aggressive rise in interest rates is significantly impacting the capital markets, and generally causing most lenders and debt investors to pause. The CMBS market is effectively shut right now, and balance sheet lenders are hesitant to lend other than to the best properties and sponsors. We had anticipated the financing markets becoming more challenging this year and focus early and deal with our 2022 and 2023 maturities. Importantly, given the $3 billion in refinancings we completed this summer at attractive spreads, we have dealt with all of our significant maturities through mid-2024, and are largely protected from near-term refinancing risk.
On the asset sale front, while there continues to be active interest from investors in New York office and retail assets without a stable financing market, it is difficult to transact with large assets but not in place debt right now. Notwithstanding the market challenges, we executed -- contracted to sell 40 Fulton $102 million and are negotiating sales of a handful of small assets. Finally, our current liquidity is a strong $3.3 billion, including $1.4 billion of cash, restricted cash and investments in U.S. treasury bills, and $1.9 billion undrawn under our $2.5 billion revolving credit facilities.
With that, I'll turn it over to the operator for Q&A.
