Thanks, Tom. For the first quarter of 2023, we reported core FFO of $43 million or $0.16 per diluted share, which compares to core FFO of $49 million or $0.18 per diluted share for the first quarter of 2022. Notably, in the first quarter, we have decided to record a $0.024 reserve on the straight line rent receivable of our tenant Signature Bank that I will discuss in more detail. Same-store property cash NOI excluding lease termination fees declined 11.4% year-over-year, primarily due to low operating expenses in 1Q '22 amid lower building utilization, coupled with a number of one-time cash revenue items in 1Q '22. On the expense side, 1Q '22 expenses were still coming off of lower levels from the meaningful and proactive expenses cuts implemented by our team amid lower building utilization during the pandemic, which contributed to positive year-over-year same-store NOI growth throughout 2020 and into early 2021. The largest year-over-year operating expense increases in 1Q '23 or R&M and payroll and in particular cleaning, real estate taxes were also higher in 1Q '23, and this was partially offset by higher tenant reimbursement income. On the revenue side, as noted in our earnings call last year, 1Q '22 results included a number of one-time cash revenue items that aggregated approximately $3.3 million inclusive of lease modification payments received. Excluding these onetime items in 1Q '22, the same store property cash NOI decline would be 7%. The Observatory generated NOI of $14.3 million in the first quarter up significantly from NOI of $7 million in the first quarter of '22. Notably, first quarter NOI was 110% of 2019. Observatory expense was $7.9 million in the first quarter. The Observatory's NOI recovery has outpaced visitation. As a reminder, the observatory historically contributed roughly a quarter of the Company's NOI and stands at approximately 23% on a trailing 12 month basis through the first quarter. Our balance sheet as of March 31, 2023 had total liquidity of $1.1 billion, which was comprised of $273 million of cash and $850 million of undrawn capacity on our revolving credit facility. At quarter end, the Company had net debt at share of $2.3 billion with a weighted average interest rate of 3.9% and a weighted average term to maturity of 6.2 years. Our ratio of net debt to adjusted EBITDA was well below PR averages at 5.7 times. We have no floating rate debt exposure, and we have a well laddered maturity schedule with no debt maturity until November 2024 when a $78 million mortgage matures. We have the balance sheet flexibility that these uncertain times demand to generate shareholder value. We can repurchase our shares, pursue investment opportunities that are additive to our New York City focused portfolio and recycle our balance sheet. In short, while we have a solid defense, our thoughts and focus are new points on the board. In the first quarter and through April 25, 2023, the Company repurchased 11.6 million of its common stock at a weighted average price of $6.11 per share. This brings the cumulative amount repurchase to 292.2 million at a weighted average price of $8.20 per share, which represents approximately 12% of total shares outstanding as of March 5, 2020, the date our share buyback program began. In our focus on capital recycling, we look hard at each and every one of our assets and pursued dispositions where we have executed on the business plan and or can recycle the proceeds into assets that align with our long-term portfolio cash flow growth objectives. As mentioned in the first quarter, we completed the disposition of our retail assets in Westport, Connecticut for our purchase price of 40 million, and subsequent to quarter end, we closed on our previously announced disposition of 500 Mamaroneck Avenue in Harrison, New York for a purchase price of 53 million. The acquisition of 298 Mulberry Street in December 2022 was funded by proceeds from these dispositions. We would note, our cash balance as of quarter end does not yet reflect net proceeds from these sales. Now, I'd like to take a moment to add additional details on Signature Bank. Our balance sheet is among the most well positioned in the sector, and we operate a well diversified business with four income streams from office, multi-family, retail, and the observatory, along with a well diversified tenant roster. Signature represents only 2.5% of total company revenues and that percentage will be further diluted when one factors in the ongoing recovery of the observatory. As Tom said, Signature is located in a very desirable asset and our highest leased office building with many contiguous floor plates that will be attractive to market should we ultimately get the space back. At this point, there is no definitive decision yet on Signature Bank's office lease. Flagstar Bank and FDIC are still within their 60 day and 120 day periods respectively to accept or reject the lease. And as of April, the tenant is current on its rent obligation. Importantly, while we do not yet know the outcome of receivership, we proactively prepare for all outcomes. Given the uncertainty of the outcome for the entirety of the remaining lease term, the appropriate accounting policy was to reserve the straight-line rent receivable balance, which is reflected in our first quarter results, and we will account for rent collected on a cash basis going forward. We have adjusted our 2023 guidance to account for this decision. As a result, our 2023 FFO guidance range is reduced by $0.02 due to the 1x straight line rent receivable reserve taken in 1Q '23 for signature. We assume continued rent -- cash rent collection in the balance of the year. Our updated full year FFO guidance range is now $0.80 to $0.84 per fully diluted share. Our same store commercial occupancy guidance is unchanged at $0.85 to $0.87. As we stated last quarter, this factor is in some conservatism on the revenue side, particularly in terms of leasing assumptions and timing of lease commencements. Our cash same store NOI guidance is also unchanged at a range of a 4% to 6% year-over-year decline. We expect the decline in same store NOI will be more pronounced in the first half of the year down roughly 10%, primarily due to low operating expenses in 1Q '22 amid lower building utilization, coupled with a number of 1x cash revenue items in 1Q '22 as discussed earlier. We expect same store NOI growth in the second half of the year will be closer to flat on average. This range still assumes an approximate 8% increase in forecasted property operating expenses and real estate taxes, which is partially offset by higher tenant reimbursement income. The increase in operating expenses is largely tied to assumptions for increased building utilization in 2023. We would note that even with this increase full year property operating expenses are expected to be approximately 3% below 2019 levels, which reflect some permanent cost savings and efficiencies we achieve from pre COVID levels. To summarize, the only impact to our guidance from signature at this time is the $0.02 straight line rent receivable reserve tied to accounting treatment and our assumption for signature cash rent collection, occupancy, and same store NOI contribution for 2023 are unchanged at this time. As mentioned, Flagstar Bank and FDIC are within their 60 and 120 day periods respectively, to accept or reject the lease, and we will revisit our guidance when we report 2Q results as relevant. That said, we want to provide full transparency in the meantime on the additional potential impacts to guidance should the outcome be a full reduction of the lease. In such an event, and assuming no additional cash rent is collected in the second half of the year, the impact on year-end commercial occupancy would be negative 320 basis points. It would have an additional approximate 2% adverse impact on our full year same store NOI growth production. It would have an additional approximate $0.02 adverse impact on our FFO guidance range in the balance of the year, which could still come within our guidance range, albeit at the lower end subject to the performance of our other underlying guidance assumptions. Our other underlying operating assumptions are unchanged. The leasing pipeline remains on track, expenses are in line with our prior expectations, and our observatory has performed well. For the observatory, we continue to expect 2023 NOI to be approximately $88 million to $96 million, up from $75 million in 2022. As a reminder, pre pandemic, the observatory generated $95 million in NOI. Our NOI guidance assumes Observatory expenses at approximately $9 million per quarter on average for 2023. The low end of our guidance range reflects the potential for a slower-than-expected Observatory ramp up due to uncontrollable factors that could impact travel and tourism and potentially unfavorable timing in terms of leasing assumptions and lease commencement. The high end of our range reflects a ramp up in Observatory performance that marginally exceeds pre-pandemic levels. Please note that, the guidance estimates and assumptions just described do not include the impact of any meaningful future lease termination fee income or any unannounced future property acquisitions, dispositions or capital markets activity. In summary, the Company has executed well on its priorities. We made further progress in our capital recycling strategy in 2023, with completed dispositions of two suburban retail assets and one additional suburban office. We remained active on share buybacks, which aggregated $282 million or 12% of total shares outstanding, since the inception of the buyback program. We prudently and strategically manage our balance sheet and have strong liquidity, which enables the Company to take advantage of attractive investment opportunities that may emerge in this period of uncertainty and capital dislocation. Our capital structure is clean with 100% owned office assets and no complex JVs, which also allows for optionality and flexibility for future financing and capitalization. Our commercial portfolio is now 86.7% occupied and 89.4% leased and we continue to benefit from tenant demand for our high-quality assets, a strong value proposition and landlords with strong balance sheets, who can deliver on their commitments. Our Observatory recovery continues with good momentum to start the year. And the fourth leg of growth, multifamily, continues to perform well and contribute to the resiliency of ESRT's cash flow. I started my work at ESRT as CFO just three years ago in April 2020. My time here from COVID to recovery has been one of accomplishment for the entire ESRT team and our stakeholders, as we maintain our acute focus on execution and results. And all the ways in which we deliver stakeholder value with our well-positioned and flexible balance sheet, a focus on disciplined capital allocation and continued commitment to ESG. This is a fantastic journey with a great team and I thank all my colleagues at ESRT, our Board, investor and analyst community, lenders and advisors for their partnership, which have been key to the successes ESRT has had to date. And I look forward to the benefits to all of us through hard and intelligent work and preparedness in the years ahead. And with that, I'll turn the call back to the operator for Q&A. Operator?
