2023 ANNUAL REPORT

Let’s  
GO NY

New York City is back! Over the past year,  
the City put to rest any lingering questions  
about its resilience as the best place in the  
world to live and work. With most economic and  
quality-of-life indicators at, near or beyond 
pre-pandemic levels, the focus turned back to 
growth and reclaiming the swagger that has 
always defined this City. This year’s annual  
report celebrates New York City and highlights 
all the ways that SL Green’s commitment to  
the City delivers for shareholders.

Chairman, Chief Executive Officer &  
Interim President

Dear Shareholders

We’re back, back in the New York groove!

It’s been years since I’ve felt this confident in the future of New York 

City or more optimistic about the trajectory of our business. After a 

challenging period, where we navigated unprecedented change by 

leaning in, keeping focused and working harder than ever, we have not 

only weathered the storm, we’ve emerged with a stronger portfolio, 

a more exciting and diversified business and an even sharper strategy 

moving forward.

We were a consistent voice proclaiming that New York City will never 

die, the people of New York are resilient and there is no replacement 

for trophy assets or premier addresses. We felt like lone optimists, but 

we didn’t get down, and never quit. 

Instead, we rolled up our sleeves, revised our business plan and relied 

on our depth of industry knowledge, expertise and longstanding 

relationships. The team was relentless, working in overdrive day and 

night. Certainly nobody did more than us when it came to leasing 

within our portfolio, developing extraordinary projects, capitalizing 

on market dislocation, and recapitalizing deals when others didn’t or 

couldn’t or wouldn’t. Our reputation and extraordinary relationships 

within the lending community allowed us to create plans to extend, 

capitalize and move forward. The banking meltdown that some 

believed was on the horizon has not materialized, and we enter this 

new chapter once again positioned for growth. 

The results are now clear. As I write this letter, our Total Return to 

Shareholders (TRS) is an incredible 131% over the prior 12 months, far 

and away leading the office sector. And through the first quarter of 

2024, that number was a healthy 24%, again atop office REITs with 

market cap above $1 billion, and highlighting our continued momentum.

An April 2024 news story in Crain’s New York Business noted this 
success, saying “it’s remarkable for the best-performing stock to also 

be the most pure-play bet” with our laser focus on New York City 

office at a time when the media tells us the City and the industry are 

dying. Well, suffice to say, we’re not surprised! Because our belief in 

this market, and the strength of our portfolio, has never wavered. 

We’re in the early innings of what we believe will be a period of 

market improvement fueled by the strength of New York City’s robust 

financial sector, a reemergence of the tech sector, a new generation 

of workers who recognize that career advancement and relationship-

building doesn’t happen at home, and increasing demand for the 

highly-amenitized office experience in which SL Green’s hospitality 

group specializes.

LOOKING BACK AT 2023

The past year was characterized by positive progress both internally 

and, for the first time since the pandemic, in external market 

conditions. Our team performed across the four key pillars of our 

business plan for 2023:

We delivered on our development projects. We announced the 

completion of One Madison in September, three months ahead of 

schedule, topped out 760 Madison, and recapitalized 245 Park Avenue, 

our next major redevelopment project. At 760 Madison, Armani is 

building out their flagship retail store, and 70% of the residential units 

are already spoken for…before the building is even complete.

SL GREEN ANNUAL REPORT 2023 3

On the leasing front, we signed 160 office leases last year, totaling 

at triple-digit rents. And contrary to the media hype, the vast majority  

1.8 million square feet, above our expectation, and our same- 

of these leases were not signed in new construction projects.

store occupancy bounced off its lows, trending to back above 90%. 

These were hard-fought wins that are a testament to our leasing, 

management and development teams. Crucially, of the leasing we  

did in 2023, more than half were new leases — which fuels our belief 

that things are headed back in the right direction.

We continue to see the FIRE sector (finance, insurance, real estate) 

as a particularly active segment of the market. McKinsey reported 

that, as of July 2023, publicly traded fintechs represented a market 

capitalization of $550 billion, a doubling in value since 2019. In that  

same period there were more than 272 fintech unicorns, with a 

We again defined the investment market in 2023. SL Green achieved 

combined valuation of $936 billion, a sevenfold increase from 39 firms 

the two most significant trades of the year, illustrating continued 

valued at $1 billion or more just five years ago. Even more exciting, this 

demand for well-located Midtown Manhattan buildings. At 245 Park 

research shows that revenues in the fintech industry are expected to

sector between 2023 and 2028. 

leasing success we’ve had in the project since then has affirmed our 

mutual conviction in the investment. And in December, we announced 

the sale of 625 Madison for more than $630 million. We achieved in 

excess of $1,100 per square foot on both transactions, something 

we had every confidence in, but the rest of the market was skeptical 

about, once again reinforcing the need to differentiate trophy assets 

and AAA locations from the rest of the market.

The legal segment was particularly active over the past year, with 

four of the top 10 NYC office leasing deals in 2023 signed by law 

firms. According to Cushman & Wakefield, law firms committed to 

4.3 million square feet of office space in 2023 across New York City, 

and nearly 17 million square feet nationwide. With finance and legal 

firms especially focused on East Midtown, our increased concentration 

on the Park Avenue spine, enhanced by the new LIRR commuter train 

We made a significant dent in our debt balances. A top priority in 

station open at Grand Central Madison, is paying dividends…literally.

2023, we were able to reduce our combined debt by over $1 billion. 

We also successfully refinanced, extended or modified over $3.7 billion 

of existing debt, including a $500 million mortgage refinancing of 

919 Third Avenue — the largest office financing in the country in 2023, 

proving our strong standing with the largest financial institutions in  

the world. It’s times like this where reputational excellence and strength  

of platform really matter.

POSITIVE INDICATORS FOR 2024

Elsewhere, Artificial Intelligence continues to play an important role in 

the market, another bright spot alongside FIRE in the tech community. 

The AI market is projected to reach $306 billion in 2024 and is expected  

to show an annual growth rate (CAGR) of 15.8% through 2030, resulting 

in a market volume of $738 billion. That’s extraordinary growth in a 

sector that has said they expect to work in offices, not at home, due to 

the fast-moving and collaborative nature of product development in AI.

In the retail sector, Manhattan availability in the 11 prime retail 

Now, as we enter what we expect to be a period of significant growth 

corridors fell to the lowest rate in nine years at the end of 2023, 

and opportunity, we are encouraged by the market fundamentals, 

while average asking rents rose for the fifth consecutive quarter, and 

which we believe are shifting to become tailwinds. Even in a higher 

consumer spending rose 6.7% year over year. Two years ago, when 

interest rate environment, there’s a solid foundation of positive

economic momentum among our strong and stable tenant base. The 

declared, “retail is back!” we again were the lone optimists. Today, 

diversity of New York City’s economy is reflected in our portfolio — and  

the strength of Manhattan retail is undeniable. Not only are leases 

is one of the core strengths of this market compared with other 

getting signed (we’ve signed five retail leases in the first quarter of 

global cities, a market where a record 192 leases were signed last year 

2024 with another dozen in the pipeline) but owner-user acquisitions 

continue to reinforce the ultimate expression of top brands’ long-

term commitment to the City. Tiffany’s reopened its Fifth Avenue 

flagship, showcasing a $500 million renovation; Prada purchased  

720 & 724 Fifth Avenue for $835 million; and Kering purchased our 

own 717 Fifth Avenue for a whopping $963 million.

Most importantly — and despite what you may read in the media —  

New York is as strong as ever, with the data to back it up: 

•  The City’s tourism numbers are the strongest since the pandemic, 

with 62 million tourists in New York in 2023, representing 93% of 

2019’s record visitors, which we expect to exceed in 2025. 

•  Subway ridership is up again, as anyone who rides the trains can tell 

you. NYC Transit reached the 1 billion ride mark six weeks ahead of 

last year’s pace, and finished 2023 with an approximately 10 percent 

year-over-year increase in ridership.

•  Crime is down across the City, with more than a 2% drop in all 

categories since spring 2023, with even greater improvement in 

Manhattan below 59th Street, where crime has dropped more than 

10%. Now, the main focus is to encourage the legislature and the 

District Attorney to work with Governor Hochul and Mayor Adams on

keeping recidivist criminals off the street and cracking down on illegal 

cannabis shops and organized serial shoplifting.

•  The housing market remains strong, with rental vacancy rate at 2.6%  

and median rents climbing 8% year over year to record levels. The condo  

market is equally strong, with median sale price of a condo reaching 

nearly $2.5 million this year, as inventory dipped 8%. People simply 

want to live here!

•  And finally, in October, the City celebrated reaching an all-time 

high in total jobs. While that number has since dipped somewhat in 

recent months, the accomplishment is extraordinary and represents 

a meteoric comeback from the lows of the pandemic. Furthermore, 

the City’s Office of Management and Budget is projecting private 

sector and officing-using job gains in 2024 that will bring the total 

employment in these categories to new record levels.

Of course, we still have challenges like all major cities do. But our City 

and State have the resources to address many of these challenges,  

and it is incumbent on all New Yorkers and businesses to express 

their desire for continued improvement in the areas of housing,  

public safety and security, sanitation, and economic development. 

Bottom line: Not only is New York not in crisis (sorry fear mongers),  

it remains the very best place in the world for an educated and diverse 

population to work and live.

2024 BUSINESS PLAN: A YEAR FOR GROWTH

With New York City and the office market on the rise, we’ve established 

another aggressive business plan for 2024.

Leasing 2 Million Square Feet

In December, we took a deep dive through every asset in our portfolio 

to demonstrate strength not just at the very top, but consistently 

throughout the best portfolio that we have ever assembled. We are 

well on our way to meeting our goal of leasing 2 million square feet 

announcing another world-renowned chef operator. For us, these 

culinary partnerships and destinations are more than leasing space. 

We are committed to doing our part to bring excitement, energy  

this year, with 630,000 square feet leased in just the first quarter, while 

and creativity to the City. 

our leasing pipeline has grown to over 1.5 million square feet. With

Office To Residential Conversion

One Madison Avenue is part of our ongoing commitment to creating 

some of the most exciting, high-quality hospitality and dining 

experiences throughout the City, not only for our building tenants, but 

for all New Yorkers. Daniel Boulud will open his first ever steakhouse,

on the success we’ve shared at One Vanderbilt with our Michelin-
starred Le Pavillon and Jo–ji. At 245 Park Avenue, we’re very close to 

Just this week, the Governor and legislature reached agreement on  

a comprehensive Office to Residential conversion program especially 

targeted to Midtown and lower Manhattan office buildings. SL Green 

has played an instrumental role in helping to get the legislation passed 

as part of the State’s new fiscal budget. We applaud Governor Hochul, 

the Senate and Assembly on the doorstep of passing a landmark office 

to residential conversion bill.  

SL GREEN ANNUAL REPORT 2023 Rendering by MOTIV.

By incentivizing the conversion of underutilized and obsolete office 

space to housing, this vital legislation will uniquely address three of 

New York’s most pressing challenges. Amidst record high Manhattan 

office vacancy, the bill will create stability in the commercial office 

market, produce the affordable and market rate housing we need to 

overcome the City’s housing crisis, and generate foot traffic to support 

local retailers and restaurants in New York’s central business districts. 

Thanks to the leadership of the Governor and our elected officials in 

Albany, as well as to Mayor Adams for his City of Yes zoning initiatives, 

the private sector is now positioned to again invest in New York City’s 

future. As part of a new conversion incentive bill, we are planning to 

be among the first out of the blocks with the conversion of 750 Third 

Avenue from office to residential use. The conversion of 750 Third will 

spur on this important new development for the City. More to come 

on this throughout the year.

expect to announce the global expansion of this world-renowned

With New York facing an ongoing housing shortage, SL Green  
has stepped up to deliver phenomenal new residential  
opportunities at all price points. At 7 Dey Street, we were  
the first to successfully build in Lower Manhattan under the  
Affordable New York program, bringing high-quality finishes 
and amenities to the building’s mix of market-rate and

Manhattan’s retail market has roared back 
to life. Over the past year, world-renowned 
retailers up and down Fifth Avenue, from 
Prada and Kering to Louis Vuitton and 
Rolex, expressed their long-term belief in 
New York by acquiring and/or investing 
in their properties. There is no greater sign 
of confidence than a brand committing 
significant capital to ensure the caliber of 
the shopping experience meets their 
client’s expectations. On the leasing front 
— world-renowned retailers Dolce & 
Gabbana, Alexander McQueen, Valentino, 
Ferrari, and Marc Jacobs have all 
signed deals in 2023 and 2024. Of note, 
Manhattan’s retail availability reached 
its lowest rate in nine years1 and remains 
steady in 20242, and Madison Avenue is 
among the highest performing submarkets 
in the City — with Giorgio Armani’s 
flagship lease at 760 Madison Avenue 
catalyzing the corridor’s resurgence.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

Overview

SL  Green  Realty  Corp.,  which  is  referred  to  as  SL  Green  or  the  Company,  a  Maryland  corporation,  and  SL  Green 
Operating Partnership, L.P., which is referred to as SLGOP or the Operating Partnership, a Delaware limited partnership, were 
formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its 
affiliated  partnerships  and  entities.  The  Company  is  a  self-managed  real  estate  investment  trust,  or  REIT,  engaged  in  the 
ownership,  management,  operation,  acquisition,  development,  redevelopment  and  repositioning  of  commercial  real  estate 
properties, principally office properties, located in the New York metropolitan area, principally Manhattan. Unless the context 
requires  otherwise,  all  references  to  "we,"  "our"  and  "us"  means  the  Company  and  all  entities  owned  or  controlled  by  the 
Company, including the Operating Partnership.

The following discussion related to our consolidated financial statements should be read in conjunction with the financial 
statements  appearing  in  Item  8  of  this  Annual  Report  on  Form  10-K.  A  discussion  of  our  results  of  operations  for  the  year 
ended  December  31,  2022  compared  to  the  year  ended  December  31,  2021  is  included  in  Part  II,  Item  7  Management's 
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  of  our  Annual  Report  on  Form  10-K  for  the  year 
ended December 31, 2022, filed with the SEC on February 17, 2023, and is incorporated by reference into this Annual Report 
on Form 10-K.

Leasing and Operating

As  of  December  31,  2023,  our  same-store  Manhattan  office  property  occupancy  inclusive  of  leases  signed  but  not 
commenced,  was  90.0%  compared  to  91.2%  as  of  December  31,  2022.  We  signed  office  leases  in  Manhattan  encompassing 
approximately 1.8 million square feet, of which approximately 1.2 million square feet represented office leases that replaced 
previously occupied space. 

According to Cushman & Wakefield, 2023 leasing activity in Manhattan totaled approximately 18.0 million square feet. 
Of the total 2023 leasing activity in Manhattan, the Midtown submarket accounted for approximately 12.6 million square feet, 
or  approximately  70.0%.  Manhattan's  overall  office  vacancy  went  from  22.2%  as  of  December  31,  2022  to  22.8%  as  of 
December 31, 2023. Overall average asking rents in Manhattan increased in 2023 by 2.4% from $71.62 per square foot as of 
December  31,  2022  to  $73.33  per  square  foot  as  of  December  31,  2023,  while  Manhattan  Class  A  asking  rents  increased  to 
$80.98 per square foot, up 2.9% from $78.72 as of December 31, 2022.

Acquisition and Disposition Activity

Overall Manhattan sales volume decreased by 39.9% in 2023 to $13.8 billion as compared to $23.0 billion in 2022. In 
2023, we continued to sell joint venture interests in quality assets as well as dispose of properties that were considered non-core 
or had a more limited growth trajectory, raising efficiently priced capital that was used primarily for debt reduction. During the 
year, we closed on the sales of all or a portion of our interests in 245 Park Avenue, 121 Greene Street and 21 East 66th Street 
for total gross valuations of $2.0 billion, generating net proceeds to the Company of $176.9 million.

Debt and Preferred Equity

In  2022  and  2023,  in  our  debt  and  preferred  equity  portfolio  we  continued  to  focus  on  underwriting  financings  for 
owners,  acquirers  or  developers  of  properties  in  New  York  City.  At  the  same  time,  we  selectively  sold  certain  investments, 
some investments were repaid, and we converted some investments into equity ownership, the proceeds of which were utilized 
to repurchase shares of common stock or for debt repayment. Our investment strategy provides us with the opportunity to fill a 
need  for  additional  debt  financing,  while  achieving  attractive  risk  adjusted  returns  to  us  on  the  investments  and  receiving  a 
significant  amount  of  additional  information  on  the  New  York  City  real  estate  market.  During  2023,  our  debt  and  preferred 
equity activities included $80.3 million, inclusive of advances under future funding obligations, discount and fee amortization, 
and  paid-in-kind  interest,  net  of  premium  amortization,  and  investments  with  a  carrying  value  of  $349.9  million  that  were 
transferred to equity ownership.

For descriptions of significant activities in 2023, refer to "Part I, Item 1. Business - Highlights from 2023."

Includes  assets  within  the  Company's  alternative  strategy  portfolio.  Within  that  portfolio,  office  includes one  building  totaling 2,048,725  square  feet, 

retail includes eight buildings totaling 286,738 square feet and development/redevelopment includes two buildings totaling 1,496,931 square feet.

As of December 31, 2023, we owned a building at 7 Dey Street / 185 Broadway that was comprised of approximately 140,382 square feet (unaudited) of 

residential  space  and  approximately  50,206  square  feet  (unaudited)  of  office  and  retail  space.  For  the  purpose  of  this  report,  we  have  included  this 

building in the number of residential properties we own. However, we have included only the residential square footage in the residential approximate 

square footage, and have listed the balance of the square footage as development square footage.

As  of  December  31,  2023,  we  also  managed  one  office  building  and  one  retail  building  owned  by  a  third  party 

encompassing  approximately  0.4  million  square  feet,  and  held  debt  and  preferred  equity  investments  with  a  book  value  of  

$346.7 million, excluding debt and preferred equity investments and other financing receivables totaling $7.9 million that are 

included in balance sheet line items other than the Debt and preferred equity investments line item.

Critical Accounting Policies and Estimates

Our  discussion  and  analysis  of  financial  condition  and  results  of  operations  is  based  on  our  consolidated  financial 

statements,  which  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States.  The 

preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, 

liabilities,  and  contingencies  as  of  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses 

during  the  reporting  periods.  We  evaluate  our  assumptions  and  estimates  on  an  ongoing  basis.  We  base  our  estimates  on 

historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of 

which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from 

other  sources.  Actual  results  may  differ  from  these  estimates  under  different  assumptions  or  conditions.  We  believe  the 

following  critical  accounting  policies  affect  our  more  significant  judgments  and  estimates  used  in  the  preparation  of  our 

consolidated financial statements.

Investment in Commercial Real Estate Properties

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the 

development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major 

investments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives.

We  recognize  the  assets  acquired,  liabilities  assumed  (including  contingencies)  and  any  noncontrolling  interests  in  an 

acquired  entity  by  allocating  the  purchase  price,  including  transaction  costs,  at  their  respective  fair  values  on  the  acquisition

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to 
be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place 
leases.

The  allocation  of  the  purchase  price  to  the  tangible  and  intangible  assets  acquired  and  liabilities  assumed  involves 
subjectivity as the allocations are based on an analysis of the respective fair values. In determining the fair value of the real 
estate acquired, the Company will use a third-party valuation which primarily utilizes cash flow projections that apply, among 
other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison 
approach,  which  utilizes  comparable  sales,  listings  and  sales  contracts.  We  assess  fair  value  of  the  acquired  leases  based  on 
estimated  cash  flow  projections  that  utilize  appropriate  discount  rates  and  available  market  information.  Estimates  of  future 
cash  flows  are  based  on  a  number  of  factors  including  the  historical  operating  results,  known  trends,  and  market/economic 
conditions  that  may  affect  the  property.  The  determined  and  allocated  fair  values  to  the  real  estate  acquired  will  affect  the 
amount of depreciation and amortization we record over the respective estimated useful lives or term of the lease.

The  Company  classifies  those  leases  under  which  the  Company  is  the  lessee  at  lease  commencement  as  finance  or 
operating leases. Leases qualify as finance leases if i) the lease transfers ownership of the asset at the end of the lease term, ii) 
the lease grants an option to purchase the asset that we are reasonably certain to exercise, iii) the lease term is for a major part 
of the remaining economic life of the asset, or iv) the present value of the lease payments exceeds substantially all of the fair 
value of the asset. Leases that do not qualify as finance leases are deemed to be operating leases. On the consolidated statements 
of  operations,  operating  leases  are  expensed  through  operating  lease  rent  while  financing  leases  are  expensed  through 
amortization and interest expense.

We incur a variety of costs in the development and leasing of our properties. After the determination is made to capitalize 
a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is 
substantially  complete  and  capitalization  must  cease  involves  a  degree  of  judgment.  The  costs  of  land  and  building  under 
development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs 
essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and 
related  costs  and  other  costs  incurred  during  the  period  of  development.  We  consider  a  construction  project  as  substantially 
completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major 
construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for 
occupancy and capitalize only those costs associated with the portions under construction.

On a periodic basis, we assess whether there are any indications that the value of our consolidated real estate properties 
may be impaired or that their carrying value may not be recoverable. A consolidated property's value is considered impaired if 
management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the 
carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying 
amount of the property over the fair value of the property as calculated in accordance with ASC 820. We assess for impairment 
indicators based on factors such as, among other things, market conditions, occupancy rates, collections, and the overall 
operating performance of the asset. If indicators of impairment are present, we evaluate real estate investments for potential 
impairment primarily utilizing cash flow projections that apply, among other things, estimated revenue and expense growth 
rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and 
sales contracts.

We also evaluate our real estate properties for impairment when a property has been classified as held for sale. Real estate 
assets held for sale are valued at the lower of their carrying value or fair value less costs to sell and depreciation expense is no 
longer recorded. See Note 4, "Properties Held for Sale and Property Dispositions."

Investments in Unconsolidated Joint Ventures

We account for our investments in unconsolidated joint ventures under the equity method of accounting in cases where 
we exercise significant influence over, but do not control, these entities and are not considered to be the primary beneficiary. 
We  consolidate  those  joint  ventures  that  we  control  or  which  are  variable  interest  entities  (each,  a  "VIE")  and  where  we  are 
considered to be the primary beneficiary. In all these joint ventures, the rights of the joint venture partner are both protective as 
well as participating. Unless we are determined to be the primary beneficiary in a VIE, these participating rights preclude us 
from consolidating these VIE entities. Determining control of the entities can be subjective in assessing which activities of the 
joint  venture  most  significantly  impact  the  economic  performance  and  whether  the  rights  of  the  joint  venture  partner  are 
protective  or  participating.    In  making  this  determination,  any  new  or  amended  joint  venture  agreement  is  assessed  by  the 
Company  for  the  activities  that  most  significantly  impact  the  joint  venture’s  economic  performance  based  on  the  business 
purpose and design of the venture. We assess the rights that are conveyed to us in the agreement and evaluate whether we are 
provided  with  participating  or  protective  rights  over  the  activities  that  most  significantly  impact  the  entity’s  economic 
performance. We also assess the rights of our joint venture partner. Such participating rights include, among other things, the 
right  to  approve/amend  the  annual  budget,  leasing  of  the  property  to  a  significant  tenant,  and  approval  of  tax  returns  and 

auditors.  If  our  joint  venture  partner  has  substantive  participating  rights  and  we  are  determined  not  to  be  the  primary 

beneficiary, we do not consolidate the entity.

These  investments  are  recorded  initially  at  cost,  as  investments  in  unconsolidated  joint  ventures,  and  subsequently 

adjusted  for  equity  in  net  income  (loss)  and  cash  contributions  and  distributions.  Equity  in  net  income  (loss)  from 

unconsolidated  joint  ventures  is  allocated  based  on  our  ownership  or  economic  interest  in  each  joint  venture  and  includes 

adjustments related to basis differences in accounting for the investment. When a capital event (as defined in each joint venture 

agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our increased 

economic interest. We recognize incentive income from unconsolidated real estate joint ventures as income to the extent it is 

earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures in excess 

of our basis in the investment are recorded as offsets to our investment balance if we remain liable for future obligations of the 

joint  venture  or  may  otherwise  be  committed  to  provide  future  additional  financial  support.  We  generally  finance  our  joint 

ventures with non-recourse debt. In certain cases we may provide guarantees or master leases for tenant space, which terminate 

upon the satisfaction of specified circumstances or repayment of the underlying loans.

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value 

of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments 

for impairment based on each joint ventures' actual and projected cash flows. Aside from charges noted in Note 6, "Investment 

in  Unconsolidated  Joint  Ventures,"  we  do  not  believe  that  the  values  of  any  of  our  equity  investments  were  impaired  as  of 

December 31, 2023.

We  may  originate  loans  for  real  estate  acquisition,  development  and  construction  ("ADC  loans")  where  we  expect  to 

receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same 

as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of 

accounting  for  investments.  Otherwise,  we  account  for  these  arrangements  consistent  with  the  accounting  for  our  debt  and 

preferred equity investments.

Lease Classification

Lease classification for leases under which the Company is the lessor is evaluated at lease commencement and leases not 

classified as sales-type leases or direct financing leases are classified as operating leases. Leases qualify as sales-type leases if 

the contract includes either transfer of ownership clauses, certain purchase options, a lease term representing a major part of the 

economic life of the asset, or the present value of the lease payments and residual guarantees provided by the lessee exceeds 

substantially  all  of  the  fair  value  of  the  asset.  Additionally,  leasing  an  asset  so  specialized  that  it  is  not  deemed  to  have  any 

value to the Company at the end of the lease term may also result in classification as a sales-type lease. Leases qualify as direct 

financing  leases  when  the  present  value  of  the  lease  payments  and  residual  value  guarantees  provided  by  the  lessee  and 

unrelated third parties exceeds substantially all of the fair value of the asset and collection of the payments is probable.

Revenue Recognition

Rental  revenue  for  operating  leases  is  recognized  on  a  straight-line  basis  over  the  term  of  the  lease  and  we  have 

determined that the collectability of substantially all of the lease payments are probable. If collectability of substantially all of 

the lease payments is assessed as not probable, rental revenue is recognized only upon actual receipt. The Company assesses the 

probability of collecting substantially all payments  under its leases based on multiple factors, including, among other things, 

payment history of the lessee, the credit rating of the lessee, historical operations and trends within the lessee’s industry, current 

and  future  economic  conditions.  If  collectability  of  substantially  all  of  the  lease  payments  is  assessed  as  not  probable,  any 

difference  between  the  rental  revenue  recognized  to  date  and  the  lease  payments  that  have  been  collected  is  recognized  as  a 

current-period adjustment to rental revenue. A subsequent change in the assessment of collectability to probable may result in a 

current-period adjustment to rental revenue for any difference between the rental revenue that would have been recognized if 

collectability had always been assessed as probable and the rental revenue recognized to date.

Rental revenue recognition commences when the leased space is available for its intended use by the lessee. To determine 

whether  the  leased  space  is  available  for  its  intended  use  by  the  lessee,  management  evaluates  whether  we  are  the  owner  of 

tenant improvements for accounting purposes or the tenant is. When management concludes that we are the owner of tenant 

improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is when such 

tenant improvements are substantially complete. In certain instances, when management concludes that we are not the owner  of 

tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. 

The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred 

rents receivable on the consolidated balance sheets.

In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and certain 

operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in 

certain building operating expenses, the tenant will pay additional rent based upon increases in the wage rate paid to porters

The  allocation  of  the  purchase  price  to  the  tangible  and  intangible  assets  acquired  and  liabilities  assumed  involves 

subjectivity as the allocations are based on an analysis of the respective fair values. In determining the fair value of the real 

estate acquired, the Company will use a third-party valuation which primarily utilizes cash flow projections that apply, among 

other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison 

approach,  which  utilizes  comparable  sales,  listings  and  sales  contracts.  We  assess  fair  value  of  the  acquired  leases  based  on 

estimated  cash  flow  projections  that  utilize  appropriate  discount  rates  and  available  market  information.  Estimates  of  future 

cash  flows  are  based  on  a  number  of  factors  including  the  historical  operating  results,  known  trends,  and  market/economic 

conditions  that  may  affect  the  property.  The  determined  and  allocated  fair  values  to  the  real  estate  acquired  will  affect  the 

amount of depreciation and amortization we record over the respective estimated useful lives or term of the lease.

The  Company  classifies  those  leases  under  which  the  Company  is  the  lessee  at  lease  commencement  as  finance  or 

operating leases. Leases qualify as finance leases if i) the lease transfers ownership of the asset at the end of the lease term, ii) 

the lease grants an option to purchase the asset that we are reasonably certain to exercise, iii) the lease term is for a major part 

of the remaining economic life of the asset, or iv) the present value of the lease payments exceeds substantially all of the fair 

value of the asset. Leases that do not qualify as finance leases are deemed to be operating leases. On the consolidated statements 

of  operations,  operating  leases  are  expensed  through  operating  lease  rent  while  financing  leases  are  expensed  through 

amortization and interest expense.

We incur a variety of costs in the development and leasing of our properties. After the determination is made to capitalize 

a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is 

substantially  complete  and  capitalization  must  cease  involves  a  degree  of  judgment.  The  costs  of  land  and  building  under 

development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs 

essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and 

related  costs  and  other  costs  incurred  during  the  period  of  development.  We  consider  a  construction  project  as  substantially 

completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major 

construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for 

occupancy and capitalize only those costs associated with the portions under construction.

On a periodic basis, we assess whether there are any indications that the value of our consolidated real estate properties 

may be impaired or that their carrying value may not be recoverable. A consolidated property's value is considered impaired if 

management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the 

carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying 

amount of the property over the fair value of the property as calculated in accordance with ASC 820. We assess for impairment 

indicators based on factors such as, among other things, market conditions, occupancy rates, collections, and the overall 

operating performance of the asset. If indicators of impairment are present, we evaluate real estate investments for potential 

impairment primarily utilizing cash flow projections that apply, among other things, estimated revenue and expense growth 

rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and 

sales contracts.

We also evaluate our real estate properties for impairment when a property has been classified as held for sale. Real estate 

assets held for sale are valued at the lower of their carrying value or fair value less costs to sell and depreciation expense is no 

longer recorded. See Note 4, "Properties Held for Sale and Property Dispositions."

Investments in Unconsolidated Joint Ventures

We account for our investments in unconsolidated joint ventures under the equity method of accounting in cases where 

we exercise significant influence over, but do not control, these entities and are not considered to be the primary beneficiary. 

We  consolidate  those  joint  ventures  that  we  control  or  which  are  variable  interest  entities  (each,  a  "VIE")  and  where  we  are 

considered to be the primary beneficiary. In all these joint ventures, the rights of the joint venture partner are both protective as 

well as participating. Unless we are determined to be the primary beneficiary in a VIE, these participating rights preclude us 

from consolidating these VIE entities. Determining control of the entities can be subjective in assessing which activities of the 

joint  venture  most  significantly  impact  the  economic  performance  and  whether  the  rights  of  the  joint  venture  partner  are 

protective  or  participating.    In  making  this  determination,  any  new  or  amended  joint  venture  agreement  is  assessed  by  the 

Company  for  the  activities  that  most  significantly  impact  the  joint  venture’s  economic  performance  based  on  the  business 

provided  with  participating  or  protective  rights  over  the  activities  that  most  significantly  impact  the  entity’s  economic 

performance. We also assess the rights of our joint venture partner. Such participating rights include, among other things, the 

right  to  approve/amend  the  annual  budget,  leasing  of  the  property  to  a  significant  tenant,  and  approval  of  tax  returns  and 

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to 

be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place 

auditors.  If  our  joint  venture  partner  has  substantive  participating  rights  and  we  are  determined  not  to  be  the  primary 
beneficiary, we do not consolidate the entity.

These  investments  are  recorded  initially  at  cost,  as  investments  in  unconsolidated  joint  ventures,  and  subsequently 
adjusted  for  equity  in  net  income  (loss)  and  cash  contributions  and  distributions.  Equity  in  net  income  (loss)  from 
unconsolidated  joint  ventures  is  allocated  based  on  our  ownership  or  economic  interest  in  each  joint  venture  and  includes 
adjustments related to basis differences in accounting for the investment. When a capital event (as defined in each joint venture 
agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our increased 
economic interest. We recognize incentive income from unconsolidated real estate joint ventures as income to the extent it is 
earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures in excess 
of our basis in the investment are recorded as offsets to our investment balance if we remain liable for future obligations of the 
joint  venture  or  may  otherwise  be  committed  to  provide  future  additional  financial  support.  We  generally  finance  our  joint 
ventures with non-recourse debt. In certain cases we may provide guarantees or master leases for tenant space, which terminate 
upon the satisfaction of specified circumstances or repayment of the underlying loans.

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value 
of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments 
for impairment based on each joint ventures' actual and projected cash flows. Aside from charges noted in Note 6, "Investment 
in  Unconsolidated  Joint  Ventures,"  we  do  not  believe  that  the  values  of  any  of  our  equity  investments  were  impaired  as  of 
December 31, 2023.

We  may  originate  loans  for  real  estate  acquisition,  development  and  construction  ("ADC  loans")  where  we  expect  to 
receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same 
as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of 
accounting  for  investments.  Otherwise,  we  account  for  these  arrangements  consistent  with  the  accounting  for  our  debt  and 
preferred equity investments.

Lease Classification

Lease classification for leases under which the Company is the lessor is evaluated at lease commencement and leases not 
classified as sales-type leases or direct financing leases are classified as operating leases. Leases qualify as sales-type leases if 
the contract includes either transfer of ownership clauses, certain purchase options, a lease term representing a major part of the 
economic life of the asset, or the present value of the lease payments and residual guarantees provided by the lessee exceeds 
substantially  all  of  the  fair  value  of  the  asset.  Additionally,  leasing  an  asset  so  specialized  that  it  is  not  deemed  to  have  any 
value to the Company at the end of the lease term may also result in classification as a sales-type lease. Leases qualify as direct 
financing  leases  when  the  present  value  of  the  lease  payments  and  residual  value  guarantees  provided  by  the  lessee  and 
unrelated third parties exceeds substantially all of the fair value of the asset and collection of the payments is probable.

Revenue Recognition

Rental  revenue  for  operating  leases  is  recognized  on  a  straight-line  basis  over  the  term  of  the  lease  and  we  have 
determined that the collectability of substantially all of the lease payments are probable. If collectability of substantially all of 
the lease payments is assessed as not probable, rental revenue is recognized only upon actual receipt. The Company assesses the 
probability of collecting substantially all payments  under  its  leases based  on multiple  factors, including, among other things, 
payment history of the lessee, the credit rating of the lessee, historical operations and trends within the lessee’s industry, current 
and  future  economic  conditions.  If  collectability  of  substantially  all  of  the  lease  payments  is  assessed  as  not  probable,  any 
difference  between  the  rental  revenue  recognized  to  date  and  the  lease  payments  that  have  been  collected  is  recognized  as  a 
current-period adjustment to rental revenue. A subsequent change in the assessment of collectability to probable may result in a 
current-period adjustment to rental revenue for any difference between the rental revenue that would have been recognized if 
collectability had always been assessed as probable and the rental revenue recognized to date.

Rental revenue recognition commences when the leased space is available for its intended use by the lessee. To determine 
whether  the  leased  space  is  available  for  its  intended  use  by  the  lessee,  management  evaluates  whether  we  are  the  owner  of 
tenant improvements for accounting purposes or the tenant is. When management concludes that we are the owner of tenant 
improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is when such 
tenant improvements are substantially complete. In certain instances, when management concludes that we are not the owner  of 
tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. 

The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred 

purpose and design of the venture. We assess the rights that are conveyed to us in the agreement and evaluate whether we are 

rents receivable on the consolidated balance sheets.

In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and certain 
operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in 
certain building operating expenses, the tenant will pay additional rent based upon increases in the wage rate paid to porters

The Company evaluates the amount expected to be collected based on current market and economic conditions, historical 

loss information, and reasonable and supportable forecasts. The Company's assumptions are derived from both internal data and 

external data which may include, among others, governmental economic projections for the New York City Metropolitan area, 

public data on recent transactions and filings for securitized debt instruments. This information is aggregated by asset class and 

adjusted for duration. Based on these inputs, loans are evaluated at the individual asset level. In certain instances, we may also 

use a probability-weighted model that considers the likelihood of multiple outcomes and the amount expected to be collected 

for each outcome. 

The  evaluation  of  the  possible  credit  deterioration  associated  with  the  performance  and/or  value  of  the  underlying 

collateral  property  as  well  as  the  financial  and  operating  capability  of  the  borrower/sponsor  requires  significant  judgment, 

which include both asset level and market assumptions over the relevant time period. 

In addition, quarterly, the Company assigns each loan a risk rating. Based on a 3-point scale, loans are rated “1” through 

“3,” from lower risk to higher risk, which ratings are defined as follows: 1 - Low Risk Assets - Low probability of loss, 2 - 

Watch List Assets - Higher potential for loss, 3 - High Risk Assets - Loss more likely than not. Loans with risk ratings of 2 or 3 

characteristics specific to the loan warrant the use of a probability-weighted model.

Financing investments that are classified as held for sale are carried at the expected amount to be collected or fair market 

value using available market information obtained through consultation with dealers or other originators of such investments as 

well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management 

may conclude not to sell an investment designated as held for sale. In such situations, the investment will be reclassified at its 

expected amount to be collected.

Other  financing  receivables  that  are  included  in  balance  sheet  line  items  other  than  the  Debt  and  preferred  equity 

investments line are also measured at the net amount expected to the be collected.

Accrued interest receivable amounts related to these debt and preferred equity investment and other financing receivables 

are recorded at the net amount expected to be collected within Other assets in the consolidated balance sheets. Write offs of 

accrued interest receivables are recognized as an expense for loan loss and other investment reserves.

over the porters' wage rate in effect during a base year or increases in the consumer price index over the index value in effect 
during a base year. In addition, many of our leases contain fixed percentage increases over the base rent to cover escalations. 
Electricity  is  most  often  supplied  by  the  landlord  either  on  a  sub-metered  basis,  or  rent  inclusion  basis  (i.e.,  a  fixed  fee  is 
included in the rent for electricity, which amount may increase based upon increases in electricity rates or increases in electrical 
usage  by  the  tenant).  Base  building  services  other  than  electricity  (such  as  heat,  air  conditioning  and  freight  elevator  service 
during business hours, and base building cleaning) are typically provided at no additional cost, with the tenant paying additional 
rent only for services which exceed base building services or for services which are provided outside normal business hours. 
These  escalations  are  based  on  actual  expenses  incurred  in  the  prior  calendar  year.  If  the  expenses  in  the  current  year  are 
different from those in the prior year, then during the current year, the escalations will be adjusted to reflect the actual expenses 
for the current year.

The Company provides its tenants with certain customary services for lease contracts such as common area maintenance 
and general security. We have elected to combine the non-lease components with the lease components of our operating lease 
agreements and account for them as a single lease component in accordance with ASC 842.

We record a gain or loss on sale of real estate assets when we no longer have a controlling financial interest in the entity

Investment income on debt and preferred equity investments is accrued based on the contractual terms of the instruments 
and when it is deemed collectible. Some debt and preferred equity investments provide for accrual of interest at specified rates, 
which  differ  from  current  payment  terms.  Interest  is  recognized  on  such  loans  at  the  accrual  rate  subject  to  management's 
determination  that  accrued  interest  is  collectible.  If  management  cannot  make  this  determination,  interest  income  above  the 
current pay rate is recognized only upon actual receipt.

The Company assesses the probability of a borrower’s ability to repay the debt and preferred equity investment similar to 
the factors noted above. We consider a debt and preferred equity investment to be past due when amounts contractually due 
have not been paid. Debt and preferred equity investments are placed on a non-accrual status at the earlier of the date at which 
payments  become  90  days  past  due  or  when,  in  the  opinion  of  management,  a  full  recovery  of  interest  income  becomes 
doubtful. Interest income recognition is resumed on any debt or preferred equity investment that is on non-accrual status when 
such debt or preferred equity investment becomes contractually current and performance is demonstrated to be resumed.

Deferred origination fees, original issue discounts and loan origination costs, if any, are recognized as an adjustment to 
interest income over the terms of the related investments using the effective interest method. Fees received in connection with 
loan commitments are also deferred until the loan is funded and are then recognized over the term of the loan as an adjustment 
to yield. Discounts or premiums associated with the purchase of loans are amortized or accreted into interest income as a yield 
adjustment  on  the  effective  interest  method  based  on  expected  cash  flows  through  the  expected  maturity  date  of  the  related 
investment. If we purchase a debt or preferred equity investment at a discount, intend to hold it until maturity and expect to 
recover  the  full  value  of  the  investment,  we  accrete  the  discount  into  income  as  an  adjustment  to  yield  over  the  term  of  the 
investment. If we purchase a debt or preferred equity investment at a discount with the intention of foreclosing on the collateral, 
we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual 
cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are 
also recognized over the term of the loan as an adjustment to yield.

We may syndicate a portion of the loans that we originate or sell the loans individually. When a transaction meets the 
criteria for sale accounting, we recognize gain or loss based on the difference between the sales price and the carrying value of 
the loan sold. Any related unamortized deferred origination fees, original issue discounts, loan origination costs, discounts or 
premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income 
on  the  consolidated  statement  of  operations.  Any  fees  received  at  the  time  of  sale  or  syndication  are  recognized  as  part  of 
investment income.

Asset management fees are recognized on a straight-line basis over the term of the asset management agreement.

Revenues  from  the  sale  of  SUMMIT  tickets  are  recognized  upon  admission  or  ticket  expirations.  Deferred  revenue 
related to unused and unexpired tickets as of December 31, 2023 and 2022 was $2.6 million and $2.0 million, respectively, and 
is included in Deferred revenue on the consolidated balance sheets.

Debt and Preferred Equity Investments

Debt and preferred equity investments are presented at the net amount expected to be collected in accordance with ASC 
326. An allowance for loan losses is deducted from the amortized cost basis of the financial assets to present the net carrying 
value at the amount expected to be collected through the expected maturity date of such investments. The expense for loan loss 
and other investment reserves is the charge to earnings to adjust the allowance for loan losses to the appropriate level. Amounts 
are written off from the allowance when we de-recognize the related investment either as a result of a sale of the investment or 
acquisition of equity interests in the collateral.

SUMMIT Operator revenue

Equity in net loss from unconsolidated joint ventures

SUMMIT Operator revenues were higher for the year ended December 31, 2023, compared to the same period in 2022 

Equity in net loss from unconsolidated joint ventures increased as a result of increased interest expense across our joint 

due primarily to increased attendance.

Investment Income

Investment income decreased due to a lower weighted average debt and preferred equity investment balance and a lower 
weighted  average  yield  for  the  period  ended  December  31,  2023  as  compared  to  the  same  period  in  2022  as  well  as  the 
recognition of previously unrecorded default interest on our preferred equity investment at 245 Park Avenue in the third quarter 
of  2022.  For  the  years  ended  December  31,  2023  and  2022,  the  weighted  average  balance  of  our  debt  and  preferred  equity 
investment  portfolio  and  the  weighted  average  yield  were  $0.6  billion  and  6.2%,  respectively,  compared  to  $1.0  billion  and 
8.3%, respectively. As of December 31, 2023, the debt and preferred equity investment portfolio had a weighted average term 
to maturity of 1.9 years excluding extension options.

Other Income

Other  income  decreased  primarily  due  to  income  related  to  the  resolution  of  the  Company's  investment  in  1591-1597 
Broadway  ($5.0  million)  in  the  second  quarter  of  2022.  This  decrease  was  offset  by  increases  in  lease  termination  income 
($1.1 million), and an increase in special servicing income for the year ended December 31, 2023 ($1.1 million) as compared to 
the same period in 2022.

Property Operating Expenses

Property operating expenses increased due primarily to acquiring 245 Park Avenue ($8.6 million) in the third quarter of 
2022 and prior to its deconsolidation in the second quarter of 2023, increased variable expenses ($7.5 million) and real estate 
taxes ($2.8 million) at our Same-Store Properties, and increased variable expenses at our Acquired Properties ($7.8 million), 
partially offset by decreased variable expenses at our Disposed Properties ($1.2 million).

SUMMIT Operator expenses were higher for the year ended December 31, 2023, compared to the same period in 2022 
due  to  additional  operating  hours  in  2023  to  accommodate  demand,  which  increased  variable  costs  such  as  labor,  security, 
cleaning and maintenance costs.

Marketing, General and Administrative Expenses

Marketing,  general  and  administrative  expenses  increased  to  $111.4  million  for  the  year  ended  December  31,  2023, 
compared to $93.8 million for the same period in 2022 due to increased compensation expense related to the non-renewal of the 
Company's former President ($18.7 million).

Interest Expense and Amortization of Deferred Financing Costs, Net of Interest Income

Interest expense and amortization of deferred financing costs, net of interest income, increased due to rising LIBOR and 
SOFR  rates,  higher  interest  expense  from  unsecured  corporate  term  loans  ($32.9  million)  and  the  revolving  credit  facility 
($20.5 million) for the year ended December 31, 2023 as compared to the year ended December 31, 2022, acquiring 245 Park 
Avenue in the third quarter of 2022 ($8.0 million) prior to its deconsolidation in the second quarter of 2023, and the refinancing 
of  100  Church  ($7.9  million)  in  the  second  quarter  of  2022.  These  increases  were  offset  primarily  by  the  repayment  of 
unsecured bonds ($20.9 million) in the third quarter of 2022. The weighted average consolidated debt balance outstanding was 
$4.6  billion  for  the  year  ended  December  31,  2023  as  compared  to  $4.6  billion  for  the  year  ended  December  31,  2022.  The 
consolidated weighted average interest rate was 4.71% for the year ended December 31, 2023 as compared to 3.55% for the 
year ended December 31, 2022.

SUMMIT Operator tax expense

The increase in SUMMIT Operator income tax expense for the year ended December 31, 2023 compared to the same 

period in 2022 was attributable to higher taxable income for SUMMIT Operator.

Depreciation and Amortization

Depreciation and amortization increased primarily due to acquiring 245 Park Avenue ($20.3 million) in the third quarter 
of 2022 and prior to its deconsolidation in the second quarter of 2023, an increase at our Acquired Properties ($8.6 million) and 
Same-Store Properties  ($2.5 million) for the year ended December 31, 2023.

venture portfolio ($67.6 million). This was partially offset by additional income at 2 Herald Square ($29.8 million) comprised 

primarily of holdover rent, interest, settlement income, lease termination income and reimbursement of attorneys' fees collected 

following the completion of legal proceedings against a former tenant and its guarantor, as well as an increase in income from 

operations at One Vanderbilt Avenue ($22.9 million).

Equity in net loss on sale of interest in unconsolidated joint venture/real estate

During  the  year  ended  December  31,  2023,  we  recognized  losses  on  the  sales  of  our  interests  in  21  East  66th  Street 

($12.7 million) and 121 Greene Street ($0.3 million). During the year ended December 31, 2022, we recognized a loss on the 

sale of our interest in the Stonehenge Portfolio (less than $0.1 million).

Purchase price and other fair value adjustments

During  the  year  ended  December  31,  2023,  we  recorded  a  $17.0  million  fair  value  adjustment  relating  to  the  50.1% 

interest we retained in 245 Park Avenue, which was deconsolidated when a 49.9% joint venture interest was sold. Additionally, 

we  recorded  a  $10.4  million  fair  value  adjustment  related  to  derivatives  that  are  not  designated  as  hedges  for  accounting 

purposes. This was partially offset by a $10.2 million purchase price adjustment related to a previous transaction. During the 

year  ended  December  31,  2022,  we  recorded  a  $6.4  million  fair  value  adjustment  related  to  an  investment  in  marketable 

securities and a $1.7 million fair value adjustment related to derivatives that are not designated as hedges.

Loss on sale of real estate, net

During the year ended December 31, 2023, we recognized a loss on the sale of a 49.9% joint venture interest in 245 Park 

Avenue  ($32.8  million).  During  the  year  ended  December  31,  2022,  we  recognized  losses  on  the  sales  of  609  Fifth  Avenue 

($80.2 million), 885 Third Avenue ($24.0 million) and 707 Eleventh Avenue ($0.8 million), offset by a gain on the sale of 1080 

Amsterdam Avenue ($17.9 million).

Depreciable Real Estate Reserves and Impairments

 During the year ended December 31, 2023, we recognized depreciable real estate reserves and impairments related to our 

leasehold  interest  at  625  Madison  Avenue  ($272.6  million),  which  was  under  contract  for  sale  as  of  December  31,  2023,  2 

Herald  Square  ($101.7  million)  and  1552-1560  Broadway  ($8.0  million)  following  an  assessment  of  the  investments  for 

recoverability.  During  the  year  ended  December  31,  2022,  we  recognized  depreciable  real  estate  reserves  and  impairments 

related to 121 Greene Street ($6.3 million) as the investment was under contract for sale as of December 31, 2022.

Loan loss and other investment reserves, net of recoveries 

During the year ended December 31, 2023, we recorded $6.9 million of loan loss reserve on one debt and preferred equity 

investment. During the year ended December 31, 2022, we did not recognize any loan loss and other investment reserves.

working  capital,  acquisitions,  development  or  redevelopment  of  properties,  tenant  improvements,  leasing  costs,  share 

repurchases, dividends to shareholders, distributions to unitholders, repurchases or repayments of outstanding indebtedness and

SUMMIT Operator revenues were higher for the year ended December 31, 2023, compared to the same period in 2022 

SUMMIT Operator revenue

due primarily to increased attendance.

Investment Income

Investment income decreased due to a lower weighted average debt and preferred equity investment balance and a lower 

weighted  average  yield  for  the  period  ended  December  31,  2023  as  compared  to  the  same  period  in  2022  as  well  as  the 

recognition of previously unrecorded default interest on our preferred equity investment at 245 Park Avenue in the third quarter 

of  2022.  For  the  years  ended  December  31,  2023  and  2022,  the  weighted  average  balance  of  our  debt  and  preferred  equity 

investment  portfolio  and  the  weighted  average  yield  were  $0.6  billion  and  6.2%,  respectively,  compared  to  $1.0  billion  and 

8.3%, respectively. As of December 31, 2023, the debt and preferred equity investment portfolio had a weighted average term 

to maturity of 1.9 years excluding extension options.

Other Income

Other  income  decreased  primarily  due  to  income  related  to  the  resolution  of  the  Company's  investment  in  1591-1597 

Broadway  ($5.0  million)  in  the  second  quarter  of  2022.  This  decrease  was  offset  by  increases  in  lease  termination  income 

($1.1 million), and an increase in special servicing income for the year ended December 31, 2023 ($1.1 million) as compared to 

the same period in 2022.

Property Operating Expenses

Property operating expenses increased due primarily to acquiring 245 Park Avenue ($8.6 million) in the third quarter of 

2022 and prior to its deconsolidation in the second quarter of 2023, increased variable expenses ($7.5 million) and real estate 

taxes ($2.8 million) at our Same-Store Properties, and increased variable expenses at our Acquired Properties ($7.8 million), 

partially offset by decreased variable expenses at our Disposed Properties ($1.2 million).

SUMMIT Operator expenses were higher for the year ended December 31, 2023, compared to the same period in 2022 

due  to  additional  operating  hours  in  2023  to  accommodate  demand,  which  increased  variable  costs  such  as  labor,  security,

cleaning and maintenance costs.

Marketing, General and Administrative Expenses

Marketing,  general  and  administrative  expenses  increased  to  $111.4  million  for  the  year  ended  December  31,  2023, 

compared to $93.8 million for the same period in 2022 due to increased compensation expense related to the non-renewal of the 

Company's former President ($18.7 million).

Interest Expense and Amortization of Deferred Financing Costs, Net of Interest Income

Interest expense and amortization of deferred financing costs, net of interest income, increased due to rising LIBOR and 

SOFR  rates,  higher  interest  expense  from  unsecured  corporate  term  loans  ($32.9  million)  and  the  revolving  credit  facility 

($20.5 million) for the year ended December 31, 2023 as compared to the year ended December 31, 2022, acquiring 245 Park 

Avenue in the third quarter of 2022 ($8.0 million) prior to its deconsolidation in the second quarter of 2023, and the refinancing 

of  100  Church  ($7.9  million)  in  the  second  quarter  of  2022.  These  increases  were  offset  primarily  by  the  repayment  of 

unsecured bonds ($20.9 million) in the third quarter of 2022. The weighted average consolidated debt balance outstanding was 

$4.6  billion  for  the  year  ended  December  31,  2023  as  compared  to  $4.6  billion  for  the  year  ended  December  31,  2022.  The 

consolidated weighted average interest rate was 4.71% for the year ended December 31, 2023 as compared to 3.55% for the 

year ended December 31, 2022.

SUMMIT Operator tax expense

Depreciation and Amortization

The increase in SUMMIT Operator income tax expense for the year ended December 31, 2023 compared to the same 

period in 2022 was attributable to higher taxable income for SUMMIT Operator.

Depreciation and amortization increased primarily due to acquiring 245 Park Avenue ($20.3 million) in the third quarter 

of 2022 and prior to its deconsolidation in the second quarter of 2023, an increase at our Acquired Properties ($8.6 million) and 

Same-Store Properties  ($2.5 million) for the year ended December 31, 2023.

Equity in net loss from unconsolidated joint ventures

Equity in net loss from unconsolidated joint ventures increased as a result of increased interest expense across our joint 
venture portfolio ($67.6 million). This was partially offset by additional income at 2 Herald Square ($29.8 million) comprised 
primarily of holdover rent, interest, settlement income, lease termination income and reimbursement of attorneys' fees collected 
following the completion of legal proceedings against a former tenant and its guarantor, as well as an increase in income from 
operations at One Vanderbilt Avenue ($22.9 million).

Cash flow from operations is primarily dependent upon the collectability of rent, the occupancy level of our portfolio, the 
net effective rental rates achieved on our leases, the collectability of rent, operating escalations and recoveries from our tenants 
and the level of operating and other costs. Additionally, we believe that our debt and preferred equity investment program will 
continue to serve as a source of operating cash flow.

We  estimate  that  for  the  year  ending  December  31,  2024,  we  expect  to  incur  $79.0  million  of  recurring  capital 
expenditures on existing consolidated properties and $80.0 million of development or redevelopment expenditures on existing 
consolidated properties, none of which will be funded by construction financing facilities or loan reserves. We expect our share 
of  capital  expenditures  at  our  joint  venture  properties  will  be  $183.6  million,  of  which  $99.2  million  will  be  funded  by 
construction  financing  facilities  or  loan  reserves.  We  expect  to  fund  capital  expenditures  from  operating  cash  flow,  existing 
liquidity,  and  borrowings  from  construction  financing  facilities.  Future  property  acquisitions  may  require  substantial  capital 
investments for refurbishment and leasing costs.

As  of  December  31,  2023,  we  had  liquidity  of  $0.9  billion,  comprised  of  $688.0  million  of  availability  under  our 
revolving  credit  facility  and  $231.4  million  of  consolidated  cash  on  hand,  inclusive  of  $9.6  million  of  marketable  securities. 
This liquidity excludes $161.9 million representing our share of cash at unconsolidated joint venture properties. We may seek to 
divest of properties, interests in properties, or debt and preferred equity investments or access private and public debt and equity 
capital  when  the  opportunity  presents  itself,  although  there  is  no  guarantee  that  this  capital  will  be  made  available  to  us  at 
efficient levels or at all. Management believes that these sources of liquidity, if we are able to access them, along with potential 
refinancing opportunities for secured and unsecured debt, will allow us to satisfy our debt and other obligations, as described 
above, upon maturity, if not before.

We  have  investments  in  several  real  estate  joint  ventures  with  various  partners  who  are  generally  considered  to  be 
financially  stable. Most  of  our joint ventures are  financed  with non-recourse  debt. We believe  that property  level  cash flows 
along with unfunded committed indebtedness and proceeds from the refinancing of outstanding secured indebtedness will be 
sufficient to fund the capital needs of our joint venture properties.

Cash Flows

The following summary discussion of our cash flows is based on our consolidated statements of cash flows in "Item 1. 
Financial Statements" and is not meant to be an all-inclusive discussion of the changes in our cash flows for the years presented 
below.

Cash, restricted cash, and cash equivalents were $335.5 million and $384.1 million as of December 31, 2023 and 2022, 
respectively,  representing  a  decrease  of  $48.6  million.  The  decrease  was  a  result  of  the  following  changes  in  cash  flows  (in

(Decrease)
Increase

Our principal sources of operating cash flow are the properties in our consolidated and joint venture portfolios and our 

debt  and  preferred  equity  portfolio.  These  sources  generate  a  relatively  consistent  stream  of  cash  flow  that  provides  us  with 

resources to pay operating expenses, debt service, and fund dividend and distribution requirements.

Cash  is  used  in  investing  activities  to  fund  acquisitions,  development  or  redevelopment  projects  and  recurring  and 

nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, 

leasing, financing and property management skills, and invest in existing buildings that meet our investment criteria. During the 

year ended December 31, 2023, when compared to the year ended December 31, 2022, we used cash primarily for the following 

investing activities (in thousands): 

Acquisitions of real estate

Capital expenditures and capitalized interest

Joint venture investments

Distributions from joint ventures

Proceeds from disposition of real estate/joint venture interest

Cash and restricted cash assumed from acquisition of real estate investment

Debt and preferred equity and other investments

Decrease in net cash provided by investing activities

Funds spent on capital expenditures, which are comprised of building and tenant improvements, decreased from $300.8 

million  for  the  year  ended  December  31,  2022  to  $259.7  million  for  the  year  ended  December  31,  2023  due  to  lower  costs 

incurred in connection with our development and redevelopment properties.

We  generally  fund  our  investment  activity  through  the  sale  of  real  estate,  the  sale  of  debt  and  preferred  equity 

investments, property-level financing, our credit facilities, senior unsecured notes, and construction loans. From time to time, 

the  Company  may  issue  common  or  preferred  stock,  or  the  Operating  Partnership  may  issue  common  or  preferred  units  of 

limited partnership interest. During the year ended December 31, 2023, when compared to the year ended December 31, 2022, 

we used cash for the following financing activities (in thousands):

Proceeds from our debt obligations

Repayments of our debt obligations

Net distribution to noncontrolling interests

Other financing activities

Repurchase of common stock

Redemption of preferred stock

Acquisition of subsidiary interest from noncontrolling interest

Dividends and distributions paid

Increase in net cash used in financing activities

Capitalization

Our authorized capital stock consists of 260,000,000 shares, $0.01 par value per share, consisting of 160,000,000 shares 

of common stock, $0.01 par value per share, 75,000,000 shares of excess stock, at $0.01 par value per share, and 25,000,000 

shares  of  preferred  stock,  $0.01  par  value  per  share.  As  of  December  31,  2023,  64,726,253  shares  of  common  stock  and  no 

shares of excess stock were issued and outstanding.

Share Repurchase Program

In  August  2016,  our  Board  of  Directors  approved  a  $1.0  billion  share  repurchase  program  under  which  we  could  buy 

shares of our common stock. The Board of Directors has since authorized five separate $500.0 million increases to the size of 

the share repurchase program in the fourth quarter of 2017, second quarter of 2018, fourth quarter of 2018, fourth quarter of 

2019, and fourth quarter of 2020 bringing the total program size to $3.5 billion.

Cash flow from operations is primarily dependent upon the collectability of rent, the occupancy level of our portfolio, the 

net effective rental rates achieved on our leases, the collectability of rent, operating escalations and recoveries from our tenants 

and the level of operating and other costs. Additionally, we believe that our debt and preferred equity investment program will 

Our principal sources of operating cash flow are the properties in our consolidated and joint venture portfolios and our 
debt  and  preferred  equity  portfolio.  These  sources  generate  a  relatively  consistent  stream  of  cash  flow  that  provides  us  with 
resources to pay operating expenses, debt service, and fund dividend and distribution requirements.

The  combined  aggregate  principal  maturities  of  mortgages  and  other  loans  payable,  the  2021  credit  facility,  senior 

unsecured  notes  (net  of  discount),  trust  preferred  securities,  our  share  of  joint  venture  debt,  including  as-of-right  extension

Cash  is  used  in  investing  activities  to  fund  acquisitions,  development  or  redevelopment  projects  and  recurring  and

leasing, financing and property management skills, and invest in existing buildings that meet our investment criteria. During the

We  estimate  that  for  the  year  ending  December  31,  2024,  we  expect  to  incur  $79.0  million  of  recurring  capital 

expenditures on existing consolidated properties and $80.0 million of development or redevelopment expenditures on existing 

consolidated properties, none of which will be funded by construction financing facilities or loan reserves. We expect our share 

of  capital  expenditures  at  our  joint  venture  properties  will  be  $183.6  million,  of  which  $99.2  million  will  be  funded  by 

construction  financing  facilities  or  loan  reserves.  We  expect  to  fund  capital  expenditures  from  operating  cash  flow,  existing 

liquidity,  and  borrowings  from  construction  financing  facilities.  Future  property  acquisitions  may  require  substantial  capital 

investments for refurbishment and leasing costs.

As  of  December  31,  2023,  we  had  liquidity  of  $0.9  billion,  comprised  of  $688.0  million  of  availability  under  our 

revolving  credit  facility  and  $231.4  million  of  consolidated  cash  on  hand,  inclusive  of  $9.6  million  of  marketable  securities. 

This liquidity excludes $161.9 million representing our share of cash at unconsolidated joint venture properties. We may seek to 

divest of properties, interests in properties, or debt and preferred equity investments or access private and public debt and equity 

capital  when  the  opportunity  presents  itself,  although  there  is  no  guarantee  that  this  capital  will  be  made  available  to  us  at 

efficient levels or at all. Management believes that these sources of liquidity, if we are able to access them, along with potential 

refinancing opportunities for secured and unsecured debt, will allow us to satisfy our debt and other obligations, as described 

above, upon maturity, if not before.

We  have  investments  in  several  real  estate  joint  ventures  with  various  partners  who  are  generally  considered  to  be 

financially  stable. Most  of  our joint ventures are financed with non-recourse  debt. We believe  that property level  cash flows 

along with unfunded committed indebtedness and proceeds from the refinancing of outstanding secured indebtedness will be 

sufficient to fund the capital needs of our joint venture properties.

Funds spent on capital expenditures, which are comprised of building and tenant improvements, decreased from $300.8 
million  for  the  year  ended  December  31,  2022  to  $259.7  million  for  the  year  ended  December  31,  2023  due  to  lower  costs 
incurred in connection with our development and redevelopment properties.

We  generally  fund  our  investment  activity  through  the  sale  of  real  estate,  the  sale  of  debt  and  preferred  equity 
investments, property-level financing, our credit facilities, senior unsecured notes, and construction loans. From time to time,

Share Repurchase Program

In  August  2016,  our  Board  of  Directors  approved  a  $1.0  billion  share  repurchase  program  under  which  we  could  buy 
shares of our common stock. The Board of Directors has since authorized five separate $500.0 million increases to the size of 
the share repurchase program in the fourth quarter of 2017, second quarter of 2018, fourth quarter of 2018, fourth quarter of 
2019, and fourth quarter of 2020 bringing the total program size to $3.5 billion.

Dividend Reinvestment and Stock Purchase Plan ("DRSPP")

In  February  2021  the  Company  filed  a  registration  statement  with  the  SEC  for  our  dividend  reinvestment  and  stock 
purchase plan, or DRSPP, which automatically became effective upon filing. The Company registered 3,500,000 shares of our

Fifth Amended and Restated 2005 Stock Option and Incentive Plan

The  Fifth  Amended  and  Restated  2005  Stock  Option  and  Incentive  Plan,  or  the  2005  Plan,  was  approved  by  the 
Company's  Board  of  Directors  in  April  2022  and  its  stockholders  in  June  2022  at  the  Company's  annual  meeting  of 
stockholders. Subject to adjustments upon certain corporate transactions or events, awards with respect to up to a maximum of 
32,210,000  fungible  units  may  be  granted  as  options,  restricted  stock,  phantom  shares,  dividend  equivalent  rights  and  other 
equity-based  awards  under  the  2005  Plan.  As  of  December  31,  2023,  3.9  million  fungible  units  were  available  for  issuance 
under  the  2005  Plan  after  reserving  for  shares  underlying  outstanding  restricted  stock  units  and  phantom  stock  units  granted 
pursuant to our Non-Employee Directors' Deferral Program and LTIP Units.

Deferred Compensation Plan for Directors

Under  our  Non-Employee  Director's  Deferral  Program,  which  commenced  July  2004,  the  Company's  non-employee 
directors may elect to defer up to 100% of their annual retainer fee, chairman fees, meeting fees and annual stock grant. Unless 
otherwise elected by a participant, fees deferred under the program shall be credited in the form of phantom stock units. The 
program provides that a director's phantom stock units generally will be settled in an equal number of shares of common stock 
upon the earlier of (i) the January 1 coincident with or the next following such director's termination of service from the Board 
of Directors or (ii) a change in control by us, as defined by the program. Phantom stock units are credited to each non-employee 
director  quarterly  using  the  closing  price  of  our  common  stock  on  the  first  business  day  of  the  respective  quarter.  Each 
participating  non-employee  director  is  also  credited  with  dividend  equivalents  or  phantom  stock  units  based  on  the  dividend 
rate for each quarter, which are either paid in cash currently or credited to the director’s account as additional phantom stock 
units.

During the year ended December 31, 2023, 39,302 phantom stock units and 27,739 shares of common stock were issued 
to our Board of Directors. We recorded compensation expense of $2.7 million during the year ended December 31, 2023 related 
to the Deferred Compensation Plan. As of December 31, 2023, there were 230,295 phantom stock units outstanding pursuant to 
our Non-Employee Director's Deferral Program.

Employee Stock Purchase Plan

In 2007, the Company's Board of Directors adopted the 2008 Employee Stock Purchase Plan, or ESPP, to provide equity-
based  incentives  to  eligible  employees.  The  ESPP  is  intended  to  qualify  as  an  "employee  stock  purchase  plan"  under 
Section 423 of the Code, and has been adopted by the board to enable our eligible employees to purchase the Company's shares 
of  common  stock  through  payroll  deductions.  The  ESPP  became  effective  on  January  1,  2008  with  a  maximum  of  500,000 
shares  of  the  common  stock  available  for  issuance,  subject  to  adjustment  upon  a  merger,  reorganization,  stock  split  or  other 
similar corporate change. The Company filed a registration statement on Form S-8 with the SEC with respect to the ESPP. The 
common stock is offered for purchase through a series of successive offering periods. Each offering period will be three months

of (1) the market value of the common stock on the first day of the offering period or (2) the market value of the common stock 

on the last day of the offering period. The ESPP was approved by our stockholders at our 2008 annual meeting of stockholders. 

As of December 31, 2023, 224,159 shares of our common stock had been issued under the ESPP.

The variable rate debt shown above generally bears interest at an interest rate based on 30-day LIBOR (0.00% and 4.39% 

as of December 31, 2023 and 2022, respectively), and adjusted Term SOFR (5.35% and 4.30% as of December 31, 2023 and

December 31, 2023 and $144.1 million as of December 31, 2022, are variable rate investments, which mitigate our exposure to 

interest rate changes on our unhedged variable rate debt. Inclusive of the mitigating effect of these investments, the net ratio of 

our variable rate debt to total debt was 3.0% and 7.0% as of December 31, 2023 and 2022, respectively.

As of December 31, 2023, our total mortgage debt (excluding our share of joint venture mortgage debt of $7.4 billion) 

consisted of $1.4 billion of fixed rate debt, including swapped variable rate debt, with an effective weighted average interest 

rate of 4.84% and $0.1 billion of variable rate debt with an effective weighted average interest rate of 6.05%.

Inclusive  of  the  mitigating  effect  of  our  debt,  preferred  equity,  and  other  investments  subject  to  variable  rates,  the  percent  of  total  debt  of  our  net 
exposure to variable rate debt was 3.0% and 7.0% as of December 31, 2023 and December 31, 2022, respectively.

The variable rate debt shown above generally bears interest at an interest rate based on 30-day LIBOR (0.00% and 4.39% 
as of December 31, 2023 and 2022, respectively), and adjusted Term SOFR (5.35% and 4.30% as of December 31, 2023 and 
2022, respectively). Our consolidated debt as of December 31, 2023 had a weighted average term to maturity of 2.69 years.

Certain  of  our  debt  and  equity  investments  and  other  investments,  with  carrying  values  of  $168.7  million  as  of 
December 31, 2023 and $144.1 million as of December 31, 2022, are variable rate investments, which mitigate our exposure to 
interest rate changes on our unhedged variable rate debt. Inclusive of the mitigating effect of these investments, the net ratio of 
our variable rate debt to total debt was 3.0% and 7.0% as of December 31, 2023 and 2022, respectively.

Mortgage Financing

As of December 31, 2023, our total mortgage debt (excluding our share of joint venture mortgage debt of $7.4 billion) 
consisted of $1.4 billion of fixed rate debt, including swapped variable rate debt, with an effective weighted average interest 
rate of 4.84% and $0.1 billion of variable rate debt with an effective weighted average interest rate of 6.05%.

2021 Credit Facility

In December 2021, we entered into an amended and restated credit facility, referred to as the 2021 credit facility, that was 
previously amended by the Company in November 2017, and was originally entered into by the Company in November 2012. 
As of December 31, 2023, the 2021 credit facility consisted of a $1.25 billion revolving credit facility, a $1.05 billion term loan 
(or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of May 15, 2026, May 15, 2027, 
and November 21, 2024, respectively. The revolving credit facility has two six-month as-of-right extension options to May 15, 
2027. We also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at

any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by 
obtaining additional commitments from our existing lenders and other financial institutions.

Restrictive Covenants

As of December 31, 2023, the 2021 credit facility bore interest at a spread over adjusted Term SOFR plus 10 basis points 
with an interest period of one or three months, as we may elect, ranging from (i) 72.5 basis points to 140 basis points for loans 
under the revolving credit facility, (ii) 80 basis points to 160 basis points for loans under Term Loan A, and (iii) 85 basis points 
to 165 basis points for loans under Term Loan B, in each case based on the credit rating assigned to the senior unsecured long 
term indebtedness of the Company. In instances where there are either only two ratings available or where there are more than 
two and the difference between them is one rating category, the applicable rating shall be the highest rating. In instances where 
there are more than two ratings and the difference between the highest and the lowest is two or more rating categories, then the 
applicable rating used is the average of the highest two, rounded down if the average is not a recognized category.

As of December 31, 2023, the applicable spread over adjusted Term SOFR plus 10 basis points for the 2021 credit 
facility was 140 basis points for the revolving credit facility, 160 basis points for Term Loan A, and 165 basis points for Term 
Loan B. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the 
revolving credit facility based on the credit rating assigned to the senior unsecured long-term indebtedness of the Company. As 
of December 31, 2023, the facility fee was 30 basis points.

As of December 31, 2023, we had $2.0 million of outstanding letters of credit, $560.0 million drawn under the revolving 
credit facility and $1.25 billion outstanding under the term loan facilities, with total undrawn capacity of $688.0 million under 
the 2021 credit facility. As of December 31, 2023 and December 31, 2022, the revolving credit facility had a carrying value of 
$554.8 million and $443.2 million, respectively, net of deferred financing costs. As of December 31, 2023 and December 31, 
2022, the term loan facilities had a carrying value of $1.2 billion and $1.2 billion, respectively, net of deferred financing costs.

The Company and the Operating Partnership are borrowers jointly and severally obligated under the 2021 credit facility.

The 2021 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

2022 Term Loan

In October 2022, we entered into a term loan agreement, referred to as the 2022 term loan. The 2022 term loan was repaid 
in full in September 2023. The 2022 term loan consisted of a $425.0 million term loan with a maturity date of October 6, 2023. 
The  2022  term  loan  had  one  six-month  as-of-right  extension  option  to  April  6,  2024.  We  also  had  an  option,  subject  to 
customary conditions, to increase the capacity of the 2022 term loan to $500.0 million on or before January 7, 2023 without the 
consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions. In 
January 2023, the 2022 term loan was increased by $25.0 million to $425.0 million.

The 2022 term loan bore interest at a spread over adjusted Term SOFR plus 0.001 basis points, ranging from 100 basis 
points to 180 basis points, in each case based on the credit rating assigned to the senior unsecured long-term indebtedness of the 
Company. In instances where there were either only two ratings available or where there was more than two and the difference 
between them was one rating category, the applicable rating was the highest rating. In instances where there were more than  
two ratings and the difference between the highest and the lowest were two or more rating categories, then the applicable rating 
used was the average of the highest two, rounded down if the average was not a recognized category. As of December 31, 2022, 
the 2022 term loan had a carrying value of $398.2 million, net of deferred financing costs.

The terms of the 2021 credit facility and our senior unsecured notes include certain restrictions and covenants which may 

limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur 

liens  and  enter  into  negative  pledge  agreements  and  dispose  of  assets,  and  which  require  compliance  with  financial  ratios 

relating  to  the  maximum  ratio  of  total  indebtedness  to  total  asset  value,  a  minimum  ratio  of  EBITDA  to  fixed  charges,  a 

maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered 

asset value. The dividend restriction referred to above provides that, we will not during any time when a default is continuing, 

make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify 

as  a  REIT  for  Federal  income  tax  purposes.  As  of  December  31,  2023  and  2022,  we  were  in  compliance  with  all  such 

covenants.

Junior Subordinated Deferrable Interest Debentures

In  June  2005,  the  Company  and  the  Operating  Partnership  issued  $100.0  million  in  unsecured  trust  preferred  securities 

through  a  newly  formed  trust,  SL  Green  Capital  Trust  I,  or  the  Trust,  which  is  a  wholly-owned  subsidiary  of  the  Operating 

Partnership.  The  securities  mature  in  2035  and  bear  interest  at  a  floating  rate  of  26  basis  points  over  the  three-month  Term 

SOFR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises 

its  right  to  defer  such  payments.  The  Trust  preferred  securities  are  redeemable  at  the  option  of  the  Operating  Partnership,  in 

whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we 

are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance 

sheets and the related payments are classified as interest expense.

Interest Rate Risk

We  are  exposed  to  changes  in  interest  rates  primarily  from  our  variable  rate  debt.  Our  exposure  to  interest  rate 

fluctuations are managed through either the use of interest rate derivative instruments and/or through our variable rate debt and 

preferred equity investments. Based on the debt outstanding as of December 31, 2023, a hypothetical 100 basis point increase in 

the floating rate interest rate curve would increase our consolidated annual interest cost, net of interest income from variable 

rate debt and preferred equity investments, by $1.0 million and would increase our share of joint venture annual interest cost by 

$12.2 million. As of December 31, 2023, $168.7 million, or 90.5%, of our $346.7 million debt and preferred equity portfolio 

was indexed to SOFR.

We recognize most derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value 

through income. If a derivative is considered a hedge, depending on the nature of the hedge, changes in the fair value of the 

derivative  will  either  be  offset  against  the  change  in  fair  value  of  the  hedged  asset,  liability,  or  firm  commitment  through 

earnings, or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings.

Our  consolidated  long-term  debt  of  $3.2  billion  bears  interest  at  fixed  rates,  and  therefore  the  fair  value  of  these 

instruments is affected by changes in the market interest rates. Our variable rate debt and variable rate joint venture debt as of 

December 31, 2023 bore interest based on a spread to LIBOR of 145 basis points and Term SOFR of 50 basis points to 565 

basis points. 

Off-Balance Sheet Arrangements

We  have  off-balance  sheet  investments,  including  joint  ventures  and  debt  and  preferred  equity  investments.  These 

investments all have varying ownership structures. A majority of our joint venture arrangements are accounted for under the 

equity  method  of  accounting  as  we  have  the  ability  to  exercise  significant  influence,  but  not  control,  over  the  operating  and 

financial decisions of these joint venture arrangements. Our off-balance sheet arrangements are discussed in Note 5, "Debt and 

Preferred Equity Investments" and Note 6, "Investments in Unconsolidated Joint Ventures" in the accompanying consolidated 

We expect to pay dividends to our stockholders based on the distributions we receive from our Operating Partnership.

To maintain our qualification as a REIT, we must pay annual dividends to our stockholders of at least 90% of our REIT 

taxable income, determined before taking into consideration the dividends paid deduction and net capital gains.

Any dividend we pay may be in the form of cash, stock, or a combination thereof, subject to IRS limitations on the use of 

stock for dividends. Additionally, if our REIT taxable income in a particular year exceeds the amount of cash dividends we pay 

in that year, we may pay stock dividends in order to maintain our REIT status and avoid certain REIT-level taxes.

 Before we pay any cash dividend, whether for Federal income tax purposes or otherwise, which would only be paid out 

of available cash to the extent permitted under the 2021 credit facility and senior unsecured notes, we must first meet both our 

operating requirements and scheduled debt service on our mortgages and loans payable.

 
 
 
obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2023, the 2021 credit facility bore interest at a spread over adjusted Term SOFR plus 10 basis points 

with an interest period of one or three months, as we may elect, ranging from (i) 72.5 basis points to 140 basis points for loans 

under the revolving credit facility, (ii) 80 basis points to 160 basis points for loans under Term Loan A, and (iii) 85 basis points 

to 165 basis points for loans under Term Loan B, in each case based on the credit rating assigned to the senior unsecured long 

term indebtedness of the Company. In instances where there are either only two ratings available or where there are more than

revolving credit facility based on the credit rating assigned to the senior unsecured long-term indebtedness of the Company. As

the 2021 credit facility. As of December 31, 2023 and December 31, 2022, the revolving credit facility had a carrying value of

January 2023, the 2022 term loan was increased by $25.0 million to $425.0 million.

The 2022 term loan bore interest at a spread over adjusted Term SOFR plus 0.001 basis points, ranging from 100 basis 

points to 180 basis points, in each case based on the credit rating assigned to the senior unsecured long-term indebtedness of the

Prior  to  2023,  Alliance  Building  Services,  or  Alliance,  and  its  affiliates,  which  provide  services  to  certain  properties 
owned by us, were previously partially owned by Gary Green, a son of Stephen L. Green, who serves as a member and as the 
chairman  emeritus  of  our  Board  of  Directors.  Alliance’s  affiliates  include  First  Quality  Maintenance,  L.P.,  or  First  Quality, 
Classic Security LLC, Bright Star Couriers LLC and Onyx Restoration Works, and provide cleaning, extermination, security, 
messenger,  and  restoration  services,  respectively.  In  addition,  First  Quality  has  the  non-exclusive  opportunity  to  provide 
cleaning  and  related  services  to  individual  tenants  at  our  properties  on  a  basis  separately  negotiated  with  any  tenant  seeking 
such additional services. The Service Corporation has entered into an arrangement with Alliance whereby it will receive a profit 
participation above a certain threshold for services provided by Alliance to certain tenants at certain buildings above the base 
services specified in their lease agreements.

Income  earned  from  the  profit  participation  prior  to  2023,  which  is  included  in  Other  income  on  the  consolidated 
statements of operations, was $1.4 million and $1.7 million for the years ended December 31, 2022 and 2021, respectively. We

services provided directly to tenants) for the years ended December 31, 2022 and 2021, respectively.

One Vanderbilt Avenue Investment

Our  Chairman  and  CEO,  Marc  Holliday,  and  our  former  President,  Andrew  Mathias,  made  investments  in  our  One 
Vanderbilt project (inclusive of the property and SUMMIT One Vanderbilt), which entitles Mr. Holliday and Mr. Mathias to 
receive  approximately  1.27%  and  0.85%,  respectively,  on  account  of  the  property  and  1.92%  and  1.28%,  respectively,  on 
account of SUMMIT One Vanderbilt, of any profits realized by the Company from its One Vanderbilt project in excess of the 
Company's capital contributions. Mr. Holliday and Mr. Mathias paid $1.4 million and $1.0 million, respectively, which equaled 
the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an 
independent third party appraisal that we obtained.

Messrs. Holliday and Mathias have the right to tender their interests in the project upon stabilization (50% within three 
years after stabilization and 100% three years or more after stabilization). In addition, the agreement calls for us to repurchase 
these interests in the event of a sale of One Vanderbilt or a transactional change of control of the Company. We also have the 
right to repurchase these interests on the 7-year anniversary of the stabilization of the project or upon the occurrence of certain 
separation events prior to the stabilization of the project relating to each of Messrs. Holliday’s and Mathias’s continued service 
with us. The price paid upon a tender of the interests will equal the liquidation value of the interests at the time, with the value 
being based on the project's sale price, if applicable, or fair market value as determined by an independent third party appraiser. 
In  2022,  stabilization  of  the  property  (but  not  SUMMIT  One  Vanderbilt)  was  achieved.  Therefore,  Messrs.  Holiday  and 
Mathias exercised their rights to tender 50% of their interests in the property (but not SUMMIT One Vanderbilt) for liquidation 
values of $17.9 million and $11.9 million, respectively, which were paid in July 2022.

One Vanderbilt Avenue Leases

In  November  2018,  we  entered  into  a  lease  agreement  with  the  One  Vanderbilt  Avenue  joint  venture  covering  certain 
floors at the property. In March 2021, the lease commenced and we relocated our corporate headquarters to the leased space. 
For the year ended December 31, 2023 and 2022 we recorded $3.0 million and $3.0 million, respectively, of rent expense under 
the  lease.  Additionally,  in  June  2021,  we,  through  a  consolidated  subsidiary,  entered  into  a  lease  agreement  with  the  One 
Vanderbilt  Avenue  joint  venture  for  SUMMIT  One  Vanderbilt,  which  commenced  operations  in  October  2021.  For  the  year 
ended  December  31,  2023,  we  recorded  $38.9  million  of  rent  expense  under  the  lease,  including  percentage  rent,  of  which 
$26.2  million  was  recognized  as  income  as  a  component  of  Equity  in  net  loss  from  unconsolidated  joint  ventures  in  our 
consolidated statements of operations. For the year ended December 31, 2022, we recorded $33.0 million of rent expense under 
the  lease,  including  percentage  rent,  of  which  $22.8  million  was  recognized  as  income  as  a  component  of  Equity  in  net  loss 
from  unconsolidated  joint  ventures  in  our  consolidated  statements  of  operations.  See  Note  20,  "Commitments  and 
Contingencies."

Insurance

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake 
and  terrorism,  excluding  nuclear,  biological,  chemical,  and  radiological  terrorism  ("NBCR")),  within  two  property  insurance 
programs and liability insurance. Separate property and liability coverage may be purchased on a stand-alone basis for certain 
assets, such as development projects. Additionally, one of our captive insurance companies, Belmont Insurance Company, or 
Belmont,  provides  coverage  for  NBCR  terrorist  acts  above  a  specified  trigger.  Belmont's  retention  is  reinsured  by  our  other 
captive insurance company, Ticonderoga Insurance Company ("Ticonderoga"). If Belmont or Ticonderoga are required to pay a 
claim under our insurance policies, we would ultimately record the loss to the extent of required payments. However, there is 
no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are 

uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated 

future  cash  flows  from  those  properties.  Additionally,  our  debt  instruments  contain  customary  covenants  requiring  us  to 

maintain insurance and we could default under our debt instruments if the cost and/or availability of certain types of insurance 

make  it  impractical  or  impossible  to  comply  with  such  covenants  relating  to  insurance.  Belmont  and  Ticonderoga  provide 

coverage solely on properties owned by the Company or its affiliates.

Furthermore, with respect to certain of our properties, including properties held by joint ventures or subject to triple net 

leases, insurance coverage is obtained by a third-party and we do not control the coverage. While we may have agreements with 

such  third  parties  to  maintain  adequate  coverage  and  we  monitor  these  policies,  such  coverage  ultimately  may  not  be 

maintained or adequately cover our risk of loss.

Funds from Operations

FFO  is  a  widely  recognized  non-GAAP  financial  measure  of  REIT  performance.  The  Company  computes  FFO  in 

accordance with standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not 

compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company 

does.  The  revised  White  Paper  on  FFO  approved  by  the  Board  of  Governors  of  NAREIT  in  April  2002,  and  subsequently 

amended  in  December  2018,  defines  FFO  as  net  income  (loss)  (computed  in  accordance  with  GAAP),  excluding  gains  (or 

losses) from sales of properties and real estate related impairment charges, plus real estate related depreciation and amortization 

and after adjustments for unconsolidated partnerships and joint ventures.

The  Company  presents  FFO  because  it  considers  it  an  important  supplemental  measure  of  the  Company’s  operating 

performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation 

of REITs, particularly those that own and operate commercial office properties. The Company also uses FFO as one of several 

criteria  to  determine  performance-based  compensation  for  members  of  its  senior  management.  FFO  is  intended  to  exclude 

GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate 

assets  diminishes  ratably  over  time.  Historically,  however,  real  estate  values  have  risen  or  fallen  with  market  conditions. 

Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions, and real 

estate related impairment charges, it provides a performance measure that, when compared year over year, reflects the impact to 

operations  from  trends  in  occupancy  rates,  rental  rates,  operating  costs,  and  interest  costs,  providing  perspective  not 

immediately  apparent  from  net  income.  FFO  does  not  represent  cash  generated  from  operating  activities  in  accordance  with 

GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of 

the  Company’s  financial  performance  or  to  cash  flow  from  operating  activities  (determined  in  accordance  with  GAAP)  as  a 

measure  of  the  Company’s  liquidity,  nor  is  it  indicative  of  funds  available  to  fund  the  Company’s  cash  needs,  including  our 

ability to make cash distributions.

FFO for the years ended December 31, 2023, 2022, and 2021 are as follows (in thousands):

Cleaning/ Security/ Messenger and Restoration Services

Prior  to  2023,  Alliance  Building  Services,  or  Alliance,  and  its  affiliates,  which  provide  services  to  certain  properties 

owned by us, were previously partially owned by Gary Green, a son of Stephen L. Green, who serves as a member and as the 

chairman  emeritus  of  our  Board  of  Directors.  Alliance’s  affiliates  include  First  Quality  Maintenance,  L.P.,  or  First  Quality, 

Classic Security LLC, Bright Star Couriers LLC and Onyx Restoration Works, and provide cleaning, extermination, security, 

messenger,  and  restoration  services,  respectively.  In  addition,  First  Quality  has  the  non-exclusive  opportunity  to  provide 

cleaning  and  related  services  to  individual  tenants  at  our  properties  on  a  basis  separately  negotiated  with  any  tenant  seeking 

such additional services. The Service Corporation has entered into an arrangement with Alliance whereby it will receive a profit 

participation above a certain threshold for services provided by Alliance to certain tenants at certain buildings above the base 

services specified in their lease agreements.

Income  earned  from  the  profit  participation  prior  to  2023,  which  is  included  in  Other  income  on  the  consolidated 

statements of operations, was $1.4 million and $1.7 million for the years ended December 31, 2022 and 2021, respectively. We 

also  recorded  expenses,  inclusive  of  capitalized  expenses,  of  $8.6  million  and  $14.0  million  for  these  services  (excluding 

services provided directly to tenants) for the years ended December 31, 2022 and 2021, respectively.

One Vanderbilt Avenue Investment

Our  Chairman  and  CEO,  Marc  Holliday,  and  our  former  President,  Andrew  Mathias,  made  investments  in  our  One 

Vanderbilt project (inclusive of the property and SUMMIT One Vanderbilt), which entitles Mr. Holliday and Mr. Mathias to 

receive  approximately  1.27%  and  0.85%,  respectively,  on  account  of  the  property  and  1.92%  and  1.28%,  respectively,  on 

account of SUMMIT One Vanderbilt, of any profits realized by the Company from its One Vanderbilt project in excess of the 

Company's capital contributions. Mr. Holliday and Mr. Mathias paid $1.4 million and $1.0 million, respectively, which equaled 

the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an 

independent third party appraisal that we obtained.

Messrs. Holliday and Mathias have the right to tender their interests in the project upon stabilization (50% within three 

years after stabilization and 100% three years or more after stabilization). In addition, the agreement calls for us to repurchase 

these interests in the event of a sale of One Vanderbilt or a transactional change of control of the Company. We also have the 

right to repurchase these interests on the 7-year anniversary of the stabilization of the project or upon the occurrence of certain 

separation events prior to the stabilization of the project relating to each of Messrs. Holliday’s and Mathias’s continued service 

with us. The price paid upon a tender of the interests will equal the liquidation value of the interests at the time, with the value 

being based on the project's sale price, if applicable, or fair market value as determined by an independent third party appraiser. 

In  2022,  stabilization  of  the  property  (but  not  SUMMIT  One  Vanderbilt)  was  achieved.  Therefore,  Messrs.  Holiday  and 

Mathias exercised their rights to tender 50% of their interests in the property (but not SUMMIT One Vanderbilt) for liquidation 

values of $17.9 million and $11.9 million, respectively, which were paid in July 2022.

For the year ended December 31, 2023 and 2022 we recorded $3.0 million and $3.0 million, respectively, of rent expense under 

the  lease.  Additionally,  in  June  2021,  we,  through  a  consolidated  subsidiary,  entered  into  a  lease  agreement  with  the  One 

Vanderbilt  Avenue  joint  venture  for  SUMMIT  One  Vanderbilt,  which  commenced  operations  in  October  2021.  For  the  year 

ended  December  31,  2023,  we  recorded  $38.9  million  of  rent  expense  under  the  lease,  including  percentage  rent,  of  which 

$26.2  million  was  recognized  as  income  as  a  component  of  Equity  in  net  loss  from  unconsolidated  joint  ventures  in  our 

consolidated statements of operations. For the year ended December 31, 2022, we recorded $33.0 million of rent expense under

or revise any forward-looking statements, whether as a result of future events, new information or otherwise.

Seasonality

Our business at SUMMIT is subject to tourism trends and weather conditions, resulting in seasonal fluctuation. In 2023 
and 2022, approximately 14.0% to 16.0% of our annual SUMMIT revenue was realized in the first quarter, 24.0% to 26.0% was 
realized in the second quarter, 28.0% to 30.0% was realized in the third quarter, and 29.0% to 31.0% was realized in the fourth 
quarter. We do not consider any other components of our business to be subject to material seasonal fluctuations.

Climate Change

With  our  roots  in  New  York  City,  we  are  at  the  center  of  one  of  the  world's  most  ambitious  climate  legislative 
environments.  Through  the  Climate  Leadership  and  Community  Protection  Act  signed  into  law  in  2019,  New  York  State 
mandated the adoption of a net-zero carbon economy statewide by 2050, with a zero-carbon electricity grid by 2040. New York 
City enacted Local Law 97 (LL97) in 2019 under the Climate Mobilization Act, setting carbon caps for large buildings starting 
in 2024 as part of a broader commitment to reducing greenhouse gas emissions by 40% by 2030, and by 80% by 2050. As our 
portfolio  is  principally  located  in  Manhattan,  these  policy  elements  represent  the  most  material  sources  of  transition  risks 
relevant to our business. We do not anticipate any material financial impact on our portfolio in the first compliance period of 
2024 to 2029.

While SL Green's portfolio  has not been substantially affected by climate-related events to New  York City real estate, 
such as Hurricane Sandy in 2012, we have continued to develop our approach to physical climate risk assessment, management, 
and  mitigation  in  order  to  manage  and  minimize  the  impacts  of  future  events.  We  have  conducted  climate-related  scenario 
analyses as part of our first Task Force on Climate-related Financial Disclosures ("TCFD") report published in 2021 and 2023, 
which  we  made  available  on  our  website.  The  Company  has  committed  to  near-term  Scope  1  and  Scope  2  science-based 
emissions  reduction  targets  with  the  SBTi,  which  were  approved  in  early  2023.  Our  goal  is  to  reduce  emissions  for  our 
operationally controlled portfolio to align it with the 1.5 degree Celsius climate scenario. 

We consider the successful management and mitigation of climate-related risks across our portfolio as an opportunity to 
raise the financial value of our buildings and pass on these benefits to our stakeholders, tenants, and investors. We believe our 
investments over the last 20 years in energy efficiency improvements and greenhouse gas emissions reductions have minimized 
the  impact  of  climate  legislation  on  our  portfolio  and  our  active  development  pipeline  sets  the  standard  for  sustainable  new 
construction  and  responsible  community  engagement.  We  leverage  years  of  operational  excellence  to  incorporate  innovative 
design and technological solutions. We also utilize recommendations from our portfolio-wide New York State Energy Research 
and  Development  Authority  ("NYSERDA")  emissions  reduction  study  to  help  lower  emissions  from  tenant  spaces  and  base 
building  operations.  Together,  these  measures  are  expected  to  minimize  our  vulnerability  to  the  physical  risks  of  climate 
change, as well as transition risks covering policy and legal, market, technology, and reputational factors.

Seasonality

Climate Change

Our business at SUMMIT is subject to tourism trends and weather conditions, resulting in seasonal fluctuation. In 2023 

and 2022, approximately 14.0% to 16.0% of our annual SUMMIT revenue was realized in the first quarter, 24.0% to 26.0% was 

realized in the second quarter, 28.0% to 30.0% was realized in the third quarter, and 29.0% to 31.0% was realized in the fourth 

quarter. We do not consider any other components of our business to be subject to material seasonal fluctuations.

With  our  roots  in  New  York  City,  we  are  at  the  center  of  one  of  the  world's  most  ambitious  climate  legislative 

environments.  Through  the  Climate  Leadership  and  Community  Protection  Act  signed  into  law  in  2019,  New  York  State 

mandated the adoption of a net-zero carbon economy statewide by 2050, with a zero-carbon electricity grid by 2040. New York 

City enacted Local Law 97 (LL97) in 2019 under the Climate Mobilization Act, setting carbon caps for large buildings starting 

in 2024 as part of a broader commitment to reducing greenhouse gas emissions by 40% by 2030, and by 80% by 2050. As our 

portfolio  is  principally  located  in  Manhattan,  these  policy  elements  represent  the  most  material  sources  of  transition  risks 

relevant to our business. We do not anticipate any material financial impact on our portfolio in the first compliance period of 

2024 to 2029.

While SL Green's portfolio  has  not been substantially affected by climate-related events to New  York  City real estate, 

such as Hurricane Sandy in 2012, we have continued to develop our approach to physical climate risk assessment, management, 

and  mitigation  in  order  to  manage  and  minimize  the  impacts  of  future  events.  We  have  conducted  climate-related  scenario 

analyses as part of our first Task Force on Climate-related Financial Disclosures ("TCFD") report published in 2021 and 2023, 

which  we  made  available  on  our  website.  The  Company  has  committed  to  near-term  Scope  1  and  Scope  2  science-based 

emissions  reduction  targets  with  the  SBTi,  which  were  approved  in  early  2023.  Our  goal  is  to  reduce  emissions  for  our 

operationally controlled portfolio to align it with the 1.5 degree Celsius climate scenario. 

We consider the successful management and mitigation of climate-related risks across our portfolio as an opportunity to 

raise the financial value of our buildings and pass on these benefits to our stakeholders, tenants, and investors. We believe our 

investments over the last 20 years in energy efficiency improvements and greenhouse gas emissions reductions have minimized 

the  impact  of  climate  legislation  on  our  portfolio  and  our  active  development  pipeline  sets  the  standard  for  sustainable  new 

construction  and  responsible  community  engagement.  We  leverage  years  of  operational  excellence  to  incorporate  innovative 

design and technological solutions. We also utilize recommendations from our portfolio-wide New York State Energy Research 

and  Development  Authority  ("NYSERDA")  emissions  reduction  study  to  help  lower  emissions  from  tenant  spaces  and  base 

building  operations.  Together,  these  measures  are  expected  to  minimize  our  vulnerability  to  the  physical  risks  of  climate 

change, as well as transition risks covering policy and legal, market, technology, and reputational factors.

SL Green Realty Corp. and SL Green Operating Partnership, L.P.
Notes to Consolidated Financial Statements
December 31, 2023 

1. Organization and Basis of Presentation

SL  Green  Realty  Corp.,  which  is  referred  to  as  the  Company  or  SL  Green,  a  Maryland  corporation,  and  SL  Green 
Operating Partnership, L.P., which is referred to as SLGOP or the Operating Partnership, a Delaware limited partnership, were 
formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its 
affiliated partnerships and entities. The Operating Partnership received a contribution of interest in the real estate properties, as 
well  as  95%  of  the  economic  interest  in  the  management,  leasing  and  construction  companies  which  are  referred  to  as  S.L. 
Green  Management  Corp,  or  the  Service  Corporation.  All  of  the  management,  leasing  and  construction  services  that  are 
provided to the properties that are wholly-owned by us and that are provided to certain joint ventures are conducted through SL 
Green  Management  LLC  and  S.L.  Green  Management  Corp.,  respectively,  which  are  100%  owned  by  the  Operating 
Partnership. The Company has qualified, and expects to qualify in the current fiscal year, as a real estate investment trust, or 
REIT, under the Internal Revenue Code of 1986, as amended, or the Code, and operates as a self-administered, self-managed 
REIT. A REIT is a legal entity that holds real estate interests and, through payments of dividends to stockholders, is permitted 
to minimize the payment of Federal income taxes at the corporate level. Unless the context requires otherwise, all references to 
"we,"  "our"  and  "us"  means  the  Company  and  all  entities  owned  or  controlled  by  the  Company,  including  the  Operating 
Partnership.

Substantially all of our assets are held by, and all of our operations are conducted through, the Operating Partnership. The 
Company is the sole managing general partner of the Operating Partnership. As of December 31, 2023, noncontrolling investors 
held,  in  the  aggregate,  a  5.75%  limited  partnership  interest  in  the  Operating  Partnership.  We  refer  to  these  interests  as  the 
noncontrolling interests in the Operating Partnership. The Operating Partnership is considered a variable interest entity, or VIE, 
in  which  we  are  the  primary  beneficiary.  See  Note  11,  "Noncontrolling  Interests  on  the  Company's  Consolidated  Financial 
Statements."

On December 31, 2023, we owned the following interests in properties in the New York metropolitan area, primarily in 

midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

The  weighted  average  leased  occupancy  for  commercial  properties  represents  the  total  leased  square  footage  divided  by  the  total  square  footage  at 
acquisition.  The weighted average leased for residential properties represents the total leased units divided by the total available units. Properties under 
construction are not included in the calculation of weighted average leased occupancy. 
Includes  assets  within  the  Company's  alternative  strategy  portfolio.  Within  that  portfolio,  office  includes one  building  totaling 2,048,725  square  feet, 
retail includes eight buildings totaling 286,738 square feet, and development/redevelopment includes two buildings totaling 1,496,931 square feet. 
As of December 31, 2023, we owned a building at 7 Dey Street / 185 Broadway that was comprised of approximately 140,382 square feet (unaudited) of 
residential space and approximately 50,206 square feet (unaudited) of office and retail space that is under development. For the purpose of this report, 
we have included this building in the number of residential properties we own. However, we have included only the residential square footage in the 
residential approximate square footage, and have listed the balance of the square footage as development square footage.

SL Green Realty Corp. and SL Green Operating Partnership, L.P.

Notes to Consolidated Financial Statements (cont.)

December 31, 2023

As  of  December  31,  2023,  we  also  managed  one  office  building  and  one  retail  building  owned  by  a  third  party 

encompassing approximately 0.4 million square feet (unaudited), and held debt and preferred equity investments with a book 

value of $346.7 million, excluding debt and preferred equity investments and other financing receivables totaling $7.9 million 

that are included in balance sheet line items other than the Debt and preferred equity investments line item.

Partnership Agreement

In accordance with the partnership agreement of the Operating Partnership, or the Operating Partnership Agreement, we 

allocate all distributions and profits and losses in proportion to the percentage of ownership interests of the respective partners, 

subject to the priority distributions with respect to preferred units and special provisions that apply to Long Term Incentive Plan 

("LTIP") Units. As the managing general partner of the Operating Partnership, we are required to take such reasonable efforts, 

as  determined  by  us  in  our  sole  discretion,  to  cause  the  Operating  Partnership  to  distribute  sufficient  amounts  to  enable  the 

payment of sufficient dividends by us to minimize any Federal income or excise tax at the Company level. Under the Operating 

Partnership Agreement, each limited partner has the right to redeem units of limited partnership interests for cash, or if we so 

elect, shares of SL Green's common stock on a one-for-one basis.

Subsequent Events

In January 2024, the Company closed on the acquisition of interests in the joint venture that owns the leasehold interest at 

2  Herald  for  no  consideration,  which  increases  the  Company's  interest  in  the  joint  venture  to  95.0%.  In  addition,  the  joint 

venture  entered  into  an  agreement  to  satisfy  the  existing  $182.5  million  mortgage  on  the  property  for  a  net  payment  of 

$7.0 million, which closed in February 2024. See Note 6, "Investments in Unconsolidated Joint Ventures."

In January 2024, together with its joint venture partner, the Company closed on the sale of the retail condominium at 717 

Fifth Avenue for a total consideration of $963.0 million. See Note 6, "Investments in Unconsolidated Joint Ventures."

2. Significant Accounting Policies

Principles of Consolidation

The  consolidated  financial  statements  include  our  accounts  and  those  of  our  subsidiaries,  which  are  wholly-owned  or 

controlled by us. Entities which we do not control through our voting interest and entities which are variable interest entities, 

but  where  we  are  not  the  primary  beneficiary,  are  accounted  for  under  the  equity  method.  See  Note  5,  "Debt  and  Preferred 

Equity Investments"  and Note  6, "Investments in Unconsolidated Joint  Ventures." All significant intercompany balances and 

transactions have been eliminated. 

We consolidate a VIE in which we are considered the primary beneficiary. The primary beneficiary is the entity that has 

(i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to 

absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

A noncontrolling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary 

not attributable, directly or indirectly, to us. Noncontrolling interests are required to be presented as a separate component of 

equity  in  the  consolidated  balance  sheet  and  the  presentation  of  net  income  is  modified  to  present  earnings  and  other 

comprehensive income (loss) attributed to controlling and noncontrolling interests.

We  assess  the  accounting  treatment  for  each  joint  venture  and  debt  and  preferred  equity  investment.  This  assessment 

includes a review of each joint venture or limited liability company agreement to determine the rights provided to each party 

and whether those rights are protective or participating. For all VIEs, we review such agreements in order to determine which 

party has the power to direct the activities that most significantly impact the entity's economic performance. In situations where 

we and our partner approve, among other things, the annual budget, receive a detailed monthly reporting package, meet on a 

quarterly  basis  to  review  the  results  of  the  joint  venture,  review  and  approve  the  joint  venture's  tax  return  before  filing,  and 

approve all leases that cover more than a nominal amount of space relative to the total rentable space at each property, we do 

not consolidate the joint venture as we consider these to be substantive participation rights that result in shared power of the 

activities  that  most  significantly  impact  the  performance  of  the  joint  venture.  Our  joint  venture  agreements  typically  contain 

certain protective rights such as requiring partner approval to sell, finance or refinance the property and the payment of capital 

expenditures and operating expenditures outside of the approved budget or operating plan.

Investment in Commercial Real Estate Properties

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the 

development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major 

replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated

equity  in  the  consolidated  balance  sheet  and  the  presentation  of  net  income  is  modified  to  present  earnings  and  other 
comprehensive income (loss) attributed to controlling and noncontrolling interests.

We  assess  the  accounting  treatment  for  each  joint  venture  and  debt  and  preferred  equity  investment.  This  assessment 
includes a review of each joint venture or limited liability company agreement to determine the rights provided to each party 
and whether those rights are protective or participating. For all VIEs, we review such agreements in order to determine which 
party has the power to direct the activities that most significantly impact the entity's economic performance. In situations where 
we and our partner approve, among other things, the annual budget, receive a detailed monthly reporting package, meet on a 
quarterly  basis  to  review  the  results  of  the  joint  venture,  review  and  approve  the  joint  venture's  tax  return  before  filing,  and 
approve all leases that cover more than a nominal amount of space relative to the total rentable space at each property, we do 
not consolidate the joint venture as we consider these to be substantive participation rights that result in shared power of the 
activities  that  most  significantly  impact  the  performance  of  the  joint  venture.  Our  joint  venture  agreements  typically  contain 
certain protective rights such as requiring partner approval to sell, finance or refinance the property and the payment of capital 
expenditures and operating expenditures outside of the approved budget or operating plan.

Investment in Commercial Real Estate Properties

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the 
development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major 
replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated

Notes to Consolidated Financial Statements (cont.)

December 31, 2023

We  recognize  the  assets  acquired,  liabilities  assumed  (including  contingencies)  and  any  noncontrolling  interests  in  an 
acquired  entity  at  their  respective  fair  values  on  the  acquisition  date.  When  we  acquire  our  partner's  equity  interest  in  an 
existing unconsolidated joint venture and gain control over the investment, we record the consolidated investment at fair value. 
The  difference  between  the  book  value  of  our  equity  investment  on  the  purchase  date  and  our  share  of  the  fair  value  of  the 
investment's purchase price is recorded as a purchase price fair value adjustment in our consolidated statements of operations. 
See Note 3, "Property Acquisitions."

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to 
be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place 
leases.  We  depreciate  the  amount  allocated  to  building  (inclusive  of  tenant  improvements)  over  their  estimated  useful  lives, 
which generally range from 3 years to 40 years. We amortize the amount allocated to the above- and below-market leases over 
the remaining term of the associated lease, which generally range from 1 year to 15 years, and record it as either an increase (in 
the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount 
allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges 
from 1 year to 15 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are 
being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and 
origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is 
terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections 
that utilize appropriate discount rates and available market information. Estimates of future cash flows are based on a number of 
factors including the historical operating results, known trends, and market/economic conditions that may affect the property. 
To  the  extent  acquired  leases  contain  fixed  rate  renewal  options  that  are  below-market  and  determined  to  be  material,  we 
amortize such below-market lease value into rental income over the renewal period. As of December 31, 2023, the weighted 
average amortization period for above-market leases, below-market leases, and in-place lease costs is 4.7 years, 8.1 years, and 
3.1 years, respectively.

The  Company  classifies  those  leases  under  which  the  Company  is  the  lessee  at  lease  commencement  as  finance  or 
operating leases. Leases qualify as finance leases if the lease transfers ownership of the asset at the end of the lease term, the 
lease grants an option to purchase the asset that we are reasonably certain to exercise, the lease term is for a major part of the 
remaining economic life of the asset, or the present value of the lease payments exceeds substantially all of the fair value of the 
asset.  Leases  that  do  not  qualify  as  finance  leases  are  deemed  to  be  operating  leases.  At  lease  commencement  the  Company 
records a lease liability which is measured as the present value of the lease payments and a right of use asset which is measured 
as the amount of the lease liability and any initial direct costs incurred. The Company applies a discount rate to determine the 
present value of the lease payments. If the rate implicit in the lease is known, the Company uses that rate. If the rate implicit in 
the lease is not known, the Company uses a discount rate reflective of the Company’s collateralized borrowing rate given the 
term of the lease. To determine the discount rate, the Company employs a third party specialist to develop an analysis based 
primarily  on  the  observable  borrowing  rates  of  the  Company,  other  REITs,  and  other  corporate  borrowers  with  long-term 
borrowings.  On  the  consolidated  statements  of  operations,  operating  leases  are  expensed  through  operating  lease  rent  while 
financing  leases  are  expensed  through  amortization  and  interest  expense.  When  applicable,  the  Company  combines  the 
consideration for lease and non-lease components in the calculation of the value of the lease obligation and right-of-use asset.

We incur a variety of costs in the development and leasing of our properties. After the determination is made to capitalize 
a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is 
substantially  complete  and  capitalization  must  cease  involves  a  degree  of  judgment.  The  costs  of  land  and  building  under 
development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs 
essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and 
related  costs  and  other  costs  incurred  during  the  period  of  development.  We  consider  a  construction  project  as  substantially 
completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major 
construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for 
occupancy, and capitalize only those costs associated with the portions under construction.

Properties  other  than  Right  of  use  assets  -  operating  leases  are  depreciated  using  the  straight-line  method  over  the 

estimated useful lives of the assets. The estimated useful lives are as follows:

Right of use assets - financing leases

lesser of 40 years or remaining lease term

Term

40 years

shorter of remaining life of the building or useful life

lesser of 40 years or remaining term of the lease

4 to 7 years

shorter of remaining term of the lease or useful life

Category

Building (fee ownership)

Building improvements

Building (leasehold interest)

Furniture and fixtures

Tenant improvements

842.

Right of use assets - operating leases are amortized over the remaining lease term. The amortization is made up of the 

principal amortization under the lease liability plus or minus the straight-line adjustment of the operating lease rent under ASC 

Depreciation  expense  (including  amortization  of  right  of  use  assets  -  financing  leases)  totaled  $221.0  million,  $190.1 

million, and $187.3 million for the years ended December 31, 2023, 2022 and 2021, respectively.

On a periodic basis, we assess whether there are any indications that the value of our real estate consolidated properties 

may be impaired or that their carrying value may not be recoverable. A consolidated property's value is considered impaired if 

management's  estimate  of  the  aggregate  future  cash  flows  (undiscounted)  to  be  generated  by  the  property  is  less  than  the 

carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying 

amount of the property over the fair value of the property as calculated in accordance with Accounting Standards Codification, 

or ASC 820. We also evaluate our real estate consolidated properties for impairment when a property has been classified as held 

for  sale.  Real  estate  assets  held  for  sale  are  valued  at  the  lower  of  their  carrying  value  or  fair  value  less  costs  to  sell  and 

depreciation expense is no longer recorded.

In April 2023, the ground rent appraisal proceeding concluded for our wholly-owned leasehold interest at 625 Madison 

Avenue. As a result of that proceeding, the ground rent was reset from the previous rent of $4.61 million per annum to a new 

rent of $20.25 million per annum, effective as of July 1, 2022. Following a strategic review of the property that addressed a 

range  of  relevant  considerations,  including  the  increase  in  ground  rent  to  an  amount  substantially  above  what  the  Company 

believed was appropriate, the Company recorded a $249.5 million charge to write down the carrying value of its investment in 

the leasehold interest to zero for the year ended December 31, 2023, which is included in Depreciable real estate reserves and 

impairments in the consolidated statement of operations.

For the years ended December 31, 2023 and 2022, we recognized $14.2 million and $5.7 million, respectively, of rental 

revenue for the amortization of aggregate below-market leases in excess of above-market leases resulting from the allocation of 

the  purchase  price  of  the  applicable  properties.  For  the  year  ended  December  31,  2021,  we  recognized  a  reduction  of  rental 

revenue of ($4.2 million) for the amortization of aggregate above-market leases in excess of below-market leases.

The  following  summarizes  our  identified  intangible  assets  (acquired  above-market  leases  and  in-place  leases)  and 

intangible liabilities (acquired below-market leases) as of December 31, 2023 and 2022 (in thousands):

Fair Value Measurements

See Note 16, "Fair Value Measurements."

Investment in Marketable Securities

At acquisition, we designate a debt security as held-to-maturity, available-for-sale, or trading. As of December 31, 2023, 
we did not have any debt securities designated as held-to-maturity or trading. We account for our available-for-sale securities at 
fair  value  pursuant  to  ASC  820-10,  with  the  net  unrealized  gains  or  losses  reported  as  a  component  of  accumulated  other 
comprehensive  income  or  loss.  The  cost  of  marketable  securities  sold  and  the  amount  reclassified  out  of  accumulated  other 
comprehensive  income  into  earnings  is  determined  using  the  specific  identification  method.  Credit  losses  are  recognized  in 
accordance with ASC 326. We account for our equity marketable securities at fair value pursuant to ASC 820-10, with the net 
unrealized gains or losses reported in net income.

As of December 31, 2023 and 2022, we held the following marketable securities (in thousands):

Deferred Financing Costs

The  cost  basis  of  the  commercial  mortgage-backed  securities  was  $11.5  million  as  of  December  31,  2023  and  2022. 
These securities mature at various times through 2030. All securities were in an unrealized loss  position as of December 31, 
2023 and 2022 with an unrealized loss of $1.9 million and fair market value of $9.6 million as of December 31, 2023, and an 
unrealized  loss  of  $0.3  million  and  a  fair  market  value  of  $11.2  million  as  of  December  31,  2022.  The  securities  were  in  a 
continuous  unrealized  loss  position  for  more  than  12  months  as  of  December  31,  2023  and  less  than  12  months  as  of 
December 31, 2022. We do not intend to sell our other securities, and it is more likely than not that we will not be required to 
sell the investment before the recovery of their amortized cost basis. 

During the year ended December 31, 2023, we did not dispose of any debt marketable securities. During the year ended 
December  31,  2022,  we  received  aggregate  net  proceeds  of  $7.8  million  from  the  sale  of  one  debt  marketable  security  and 
$3.7  million  from  the  repayment  of  one  debt  marketable  security.  During  the  year  ended  December  31,  2021,  we  received 
aggregate net proceeds of $4.5 million from the repayment of one debt marketable security.

that  was  held  as  of  December  31,  2021  during  the  year  ended  December  31,  2022,  for  which  we  received  aggregate  net 

proceeds of $4.2 million. We did not dispose of any equity marketable securities during the year ended December 31, 2021. We 

recognized  $6.5  million  of  realized  losses  and  $0.6  million  of  unrealized  gains  for  the  years  ended  December  31,  2022  and 

2021, respectively.

Investments in Unconsolidated Joint Ventures

We account for our investments in unconsolidated joint ventures under the equity method of accounting in cases where 

we exercise significant influence over, but do not control, these entities and are not considered to be the primary beneficiary. 

We  consolidate  those  joint  ventures  that  we  control  or  which  are  variable  interest  entities  (each,  a  "VIE")  and  where  we  are 

considered to be the primary beneficiary. In all these joint ventures, the rights of the joint venture partner are both protective as 

well as participating. Unless we are determined to be the primary beneficiary in a VIE, these participating rights preclude us 

from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint 

ventures,  and  subsequently  adjusted  for  equity  in  net  income  (loss)  and  cash  contributions  and  distributions.  Equity  in  net 

income (loss) from unconsolidated joint ventures is allocated based on our ownership or economic interest in each joint venture 

and includes adjustments related to basis differences in accounting for the investment. When a capital event (as defined in each 

joint venture agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our 

increased  economic  interest.  We  recognize  incentive  income  from  unconsolidated  real  estate  joint  ventures  as  income  to  the 

extent it is earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures 

in  excess  of  our  basis  in  the  investment  are  recorded  as  offsets  to  our  investment  balance  if  we  remain  liable  for  future 

obligations  of  the  joint  venture  or  may  otherwise  be  committed  to  provide  future  additional  financial  support.  We  generally 

finance our joint ventures with non-recourse debt. In certain cases we may provide guarantees or master leases, which terminate 

upon the satisfaction of specified circumstances or repayment of the underlying loans.

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value 

of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments 

for impairment based on each joint ventures' actual and projected cash flows. Aside from charges noted in Note 6, "Investment 

in  Unconsolidated  Joint  Ventures,"  we  do  not  believe  that  the  values  of  any  of  our  equity  investments  were  impaired  at 

December 31, 2023.

We  may  originate  loans  for  real  estate  acquisition,  development  and  construction  ("ADC  loans"),  where  we  expect  to 

receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same 

as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of 

accounting  for  investments.  Otherwise,  we  account  for  these  arrangements  consistent  with  the  accounting  for  our  debt  and 

preferred equity investments.

Deferred Lease Costs

Deferred lease costs consist of incremental fees and direct costs that would not have been incurred if the lease had not 

been obtained and are amortized on a straight-line basis over the related lease term. Certain of our employees provide leasing 

services to the wholly-owned properties. For the years ended December 31, 2023, 2022 and 2021, $6.8 million, $6.6 million, 

and $6.2 million of their compensation, respectively, was capitalized and is amortized over an estimated average lease term of 

Deferred  financing  costs  represent  commitment  fees,  legal,  title  and  other  third  party  costs  associated  with  obtaining 

commitments  for  financing  which  result  in  a  closing  of  such  financing.  These  costs  are  amortized  over  the  terms  of  the 

respective  agreements.  Unamortized  deferred  financing  costs  are  expensed  when  the  associated  debt  is  refinanced  or  repaid 

before maturity. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is 

determined that the financing will not close. Deferred financing costs related to a recognized debt liability are presented in the 

consolidated balance sheet as a direct deduction from the carrying amount of that debt liability.

Lease Classification

Lease classification for leases under which the Company is the lessor is evaluated at lease commencement and leases not 

classified as sales-type leases or direct financing leases are classified as operating leases. Leases qualify as sales-type leases if 

the contract includes either transfer of ownership clauses, certain purchase options, a lease term representing a major part of the 

economic life of the asset, or the present value of the lease payments and residual guarantees provided by the lessee exceeds

Fair Value Measurements

Investment in Marketable Securities

At acquisition, we designate a debt security as held-to-maturity, available-for-sale, or trading. As of December 31, 2023, 

we did not have any debt securities designated as held-to-maturity or trading. We account for our available-for-sale securities at 

fair  value  pursuant  to  ASC  820-10,  with  the  net  unrealized  gains  or  losses  reported  as  a  component  of  accumulated  other 

comprehensive  income  or  loss.  The  cost  of  marketable  securities  sold  and  the  amount  reclassified  out  of  accumulated  other 

comprehensive  income  into  earnings  is  determined  using  the  specific  identification  method.  Credit  losses  are  recognized  in 

accordance with ASC 326. We account for our equity marketable securities at fair value pursuant to ASC 820-10, with the net 

unrealized gains or losses reported in net income.

As of December 31, 2023 and 2022, we held the following marketable securities (in thousands):

The  cost  basis  of  the  commercial  mortgage-backed  securities  was  $11.5  million  as  of  December  31,  2023  and  2022. 

These securities mature at various times through 2030. All securities were in an unrealized loss  position as of December 31, 

2023 and 2022 with an unrealized loss of $1.9 million and fair market value of $9.6 million as of December 31, 2023, and an 

unrealized  loss  of  $0.3  million  and  a  fair  market  value  of  $11.2  million  as  of  December  31,  2022.  The  securities  were  in  a 

continuous  unrealized  loss  position  for  more  than  12  months  as  of  December  31,  2023  and  less  than  12  months  as  of 

December 31, 2022. We do not intend to sell our other securities, and it is more likely than not that we will not be required to 

sell the investment before the recovery of their amortized cost basis. 

During the year ended December 31, 2023, we did not dispose of any debt marketable securities. During the year ended 

December  31,  2022,  we  received  aggregate  net  proceeds  of  $7.8  million  from  the  sale  of  one  debt  marketable  security  and 

$3.7  million  from  the  repayment  of  one  debt  marketable  security.  During  the  year  ended  December  31,  2021,  we  received 

aggregate net proceeds of $4.5 million from the repayment of one debt marketable security. 

We held no equity marketable securities as of December 31, 2023 and 2022 as we sold the one equity marketable security 
that  was  held  as  of  December  31,  2021  during  the  year  ended  December  31,  2022,  for  which  we  received  aggregate  net 
proceeds of $4.2 million. We did not dispose of any equity marketable securities during the year ended December 31, 2021. We 
recognized  $6.5  million  of  realized  losses  and  $0.6  million  of  unrealized  gains  for  the  years  ended  December  31,  2022  and 
2021, respectively.

Investments in Unconsolidated Joint Ventures

We account for our investments in unconsolidated joint ventures under the equity method of accounting in cases where 
we exercise significant influence over, but do not control, these entities and are not considered to be the primary beneficiary. 
We  consolidate  those  joint  ventures  that  we  control  or  which  are  variable  interest  entities  (each,  a  "VIE")  and  where  we  are 
considered to be the primary beneficiary. In all these joint ventures, the rights of the joint venture partner are both protective as 
well as participating. Unless we are determined to be the primary beneficiary in a VIE, these participating rights preclude us 
from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint 
ventures,  and  subsequently  adjusted  for  equity  in  net  income  (loss)  and  cash  contributions  and  distributions.  Equity  in  net 
income (loss) from unconsolidated joint ventures is allocated based on our ownership or economic interest in each joint venture 
and includes adjustments related to basis differences in accounting for the investment. When a capital event (as defined in each 
joint venture agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our 
increased  economic  interest.  We  recognize  incentive  income  from  unconsolidated  real  estate  joint  ventures  as  income  to  the 
extent it is earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures 
in  excess  of  our  basis  in  the  investment  are  recorded  as  offsets  to  our  investment  balance  if  we  remain  liable  for  future 
obligations  of  the  joint  venture  or  may  otherwise  be  committed  to  provide  future  additional  financial  support.  We  generally 
finance our joint ventures with non-recourse debt. In certain cases we may provide guarantees or master leases, which terminate 
upon the satisfaction of specified circumstances or repayment of the underlying loans.

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value 
of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments 
for impairment based on each joint ventures' actual and projected cash flows. Aside from charges noted in Note 6, "Investment 
in  Unconsolidated  Joint  Ventures,"  we  do  not  believe  that  the  values  of  any  of  our  equity  investments  were  impaired  at

We  may  originate  loans  for  real  estate  acquisition,  development  and  construction  ("ADC  loans"),  where  we  expect  to

and $6.2 million of their compensation, respectively, was capitalized and is amortized over an estimated average lease term of 
seven years.

Deferred Financing Costs

Deferred  financing  costs  represent  commitment  fees,  legal,  title  and  other  third  party  costs  associated  with  obtaining 
commitments  for  financing  which  result  in  a  closing  of  such  financing.  These  costs  are  amortized  over  the  terms  of  the 
respective  agreements.  Unamortized  deferred  financing  costs  are  expensed  when  the  associated  debt  is  refinanced  or  repaid

substantially  all  of  the  fair  value  of  the  asset.  Additionally,  leasing  an  asset  so  specialized  that  it  is  not  deemed  to  have  any 
value to the Company at the end of the lease term may also result in classification as a sales-type lease. Leases qualify as direct 
financing  leases  when  the  present  value  of  the  lease  payments  and  residual  value  guarantees  provided  by  the  lessee  and 
unrelated third parties exceeds substantially all of the fair value of the asset and collection of the payments is probable.

Revenue Recognition

Rental  revenue  for  operating  leases  is  recognized  on  a  straight-line  basis  over  the  term  of  the  lease.  Rental  revenue 

recognition commences when the leased space is available for its intended use by the lessee. 

To determine whether the leased space is available for its intended use by the lessee, management evaluates whether we 
or  the  tenant  are  the  owner  of  tenant  improvements  for  accounting  purposes.  When  management  concludes  that  we  are  the 
owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which 
is when such tenant improvements are substantially complete. In certain instances, when management concludes that we are not 
the owner  of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. 

The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred 

investment income.

rents receivable on the consolidated balance sheets.

In addition to base rent, our tenants also generally will pay variable rent which represents their pro rata share of increases 
in real estate taxes and certain operating expenses for the building over a base year. In some leases, in lieu of paying additional 
rent based upon increases in certain building operating expenses, the tenant will pay additional rent based upon increases in the 
wage rate paid to porters over the porters' wage rate in effect during a base year or increases in the consumer price index over 
the index value in effect during a base year. In addition, many of our leases contain fixed percentage increases over the base 
rent to cover escalations. Electricity is most often supplied by the landlord either on a sub-metered basis, or rent inclusion basis 
(i.e., a fixed fee is included in the rent for electricity, which amount may increase based upon increases in electricity rates or 
increases  in  electrical  usage  by  the  tenant).  Base  building  services  other  than  electricity  (such  as  heat,  air  conditioning  and 
freight elevator service during business hours, and base building cleaning) are typically provided at no additional cost, with the 
tenant paying additional rent only for services which exceed base building services or for services which are provided outside 
normal business hours. These escalations are based on actual expenses incurred in the prior calendar year. If the expenses in the 
current year are different from those in the prior year, then during the current year, the escalations will be adjusted to reflect the 
actual expenses for the current year.

Rental  revenue  is  recognized  if  collectability  is  probable.  If  collectability  of  substantially  all  of  the  lease  payments  is 
assessed as not probable, any difference between the rental revenue recognized to date and the lease payments that have been 
collected is recognized as a current-period adjustment to rental revenue. A subsequent change in the assessment of collectability 
to probable may result in a current-period adjustment to rental revenue for any difference between the rental revenue that would 
have been recognized if collectability had always been assessed as probable and the rental revenue recognized to date.

The Company provides its tenants with certain customary services for lease contracts such as common area maintenance 
and general security. We have elected to combine the non-lease components with the lease components of our operating lease 
agreements and account for them as a single lease component in accordance with ASC 842.

We record a gain or loss on sale of real estate assets when we no longer have a controlling financial interest in the entity 

owning the real estate, a contract exists with a third party and that third party has control of the assets acquired.

Investment income on debt and preferred equity investments is accrued based on the contractual terms of the instruments 
and when it is deemed collectible. Some debt and preferred equity investments provide for accrual of interest at specified rates, 
which  differ  from  current  payment  terms.  Interest  is  recognized  on  such  loans  at  the  accrual  rate  subject  to  management's 
determination  that  accrued  interest  is  collectible.  If  management  cannot  make  this  determination,  interest  income  above  the 
current pay rate is recognized only upon actual receipt.

Deferred origination fees, original issue discounts and loan origination costs, if any, are recognized as an adjustment to 
interest income over the terms of the related investments using the effective interest method. Fees received in connection with 
loan commitments are also deferred until the loan is funded and are then recognized over the term of the loan as an adjustment 
to yield. Discounts or premiums associated with the purchase of loans are amortized or accreted into interest income as a yield 
adjustment  on  the  effective  interest  method  based  on  expected  cash  flows  through  the  expected  maturity  date  of  the  related 
investment. If we purchase a debt or preferred equity investment at a discount, intend to hold it until maturity and expect to 
recover  the  full  value  of  the  investment,  we  accrete  the  discount  into  income  as  an  adjustment  to  yield  over  the  term  of  the 
investment. If we purchase a debt or preferred equity investment at a discount with the intention of foreclosing on the collateral,

we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual 

cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are 

also recognized over the term of the loan as an adjustment to yield.

We consider a debt and preferred equity investment to be past due when amounts contractually due have not been paid. 

Debt and preferred equity investments are placed on a non-accrual status at the earlier of the date at which payments become 90 

days  past  due  or  when,  in  the  opinion  of  management,  a  full  recovery  of  interest  income  becomes  doubtful.  Interest  income 

recognition  is  resumed  on  any  debt  or  preferred  equity  investment  that  is  on  non-accrual  status  when  such  debt  or  preferred 

equity investment becomes contractually current and performance is demonstrated to be resumed.

We may syndicate a portion of the loans that we originate or sell the loans individually. When a transaction meets the 

criteria for sale accounting, we recognize gain or loss based on the difference between the sales price and the carrying value of 

the loan sold. Any related unamortized deferred origination fees, original issue discounts, loan origination costs, discounts or 

premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income 

on  the  consolidated  statement  of  operations.  Any  fees  received  at  the  time  of  sale  or  syndication  are  recognized  as  part  of 

Asset management fees are recognized on a straight-line basis over the term of the asset management agreement.

Revenues  from  the  sale  of  SUMMIT  tickets  are  recognized  upon  admission  or  ticket  expirations.  Deferred  revenue 

related to unused and unexpired tickets as of December 31, 2023 and 2022 was $2.6 million and $2.0 million, respectively, and 

is included in Deferred revenue on the consolidated balance sheets.

Debt and Preferred Equity Investments

Debt and preferred equity investments are presented at the net amount expected to be collected in accordance with ASC 

326. An allowance for loan losses is deducted from the amortized cost basis of the financial assets to present the net carrying 

value at the amount expected to be collected through the expected maturity date of such investments. The expense for loan loss 

and other investment reserves is the charge to earnings to adjust the allowance for loan losses to the appropriate level. Amounts 

are written off from the allowance when we de-recognize the related investment either as a result of a sale of the investment or 

acquisition of equity interests in the collateral.

The Company evaluates the amount expected to be collected based on current market and economic conditions, historical 

loss information, and reasonable and supportable forecasts.  The Company's assumptions are derived from both internal data 

and external data which may include, among others, governmental economic projections for the New York City Metropolitan 

area,  public  data  on  recent  transactions  and  filings  for  securitized  debt  instruments.  This  information  is  aggregated  by  asset 

class and adjusted for duration. Based on these inputs, loans are evaluated at the individual asset level. In certain instances, we 

may also use a probability-weighted model that considers the likelihood of multiple outcomes and the amount expected to be 

collected for each outcome.

The  evaluation  of  the  possible  credit  deterioration  associated  with  the  performance  and/or  value  of  the  underlying 

collateral  property  as  well  as  the  financial  and  operating  capability  of  the  borrower/sponsor  requires  significant  judgment, 

which include both asset level and market assumptions over the relevant time period. 

In addition, quarterly, the Company assigns each loan a risk rating. Based on a 3-point scale, loans are rated “1” through 

“3,” from lower risk to higher risk, which ratings are defined as follows: 1 - Low Risk Assets - Low probability of loss, 2 - 

Watch List Assets - Higher potential for loss, 3 - High Risk Assets - Loss more likely than not. Loans with risk ratings of 2 or 

above are evaluated to determine whether the expected risk of loss is  appropriately captured through the combination of our 

expectations  of  current  conditions,  historical  loss  information  and  supportable  forecasts  described  above  or  whether  risk 

characteristics specific to the loan warrant the use of a probability-weighted model.

Financing investments that are classified as held for sale are carried at the expected amount to be collected or fair market 

value using available market information obtained through consultation with dealers or other originators of such investments as 

well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management 

may conclude not to sell an investment designated as held for sale. In such situations, the investment will be reclassified at its 

expected amount to be collected.

Other  financing  receivables  that  are  included  in  balance  sheet  line  items  other  than  the  Debt  and  preferred  equity 

investments line are also measured at the net amount expected to be collected.

We may syndicate a portion of the loans that we originate or sell the loans individually. When a transaction meets the 
criteria for sale accounting, we recognize gain or loss based on the difference between the sales price and the carrying value of 
the loan sold. Any related unamortized deferred origination fees, original issue discounts, loan origination costs, discounts or 
premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income 
on  the  consolidated  statement  of  operations.  Any  fees  received  at  the  time  of  sale  or  syndication  are  recognized  as  part  of 
investment income.

Asset management fees are recognized on a straight-line basis over the term of the asset management agreement.

Revenues  from  the  sale  of  SUMMIT  tickets  are  recognized  upon  admission  or  ticket  expirations.  Deferred  revenue 
related to unused and unexpired tickets as of December 31, 2023 and 2022 was $2.6 million and $2.0 million, respectively, and 
is included in Deferred revenue on the consolidated balance sheets.

Debt and Preferred Equity Investments

Debt and preferred equity investments are presented at the net amount expected to be collected in accordance with ASC 
326. An allowance for loan losses is deducted from the amortized cost basis of the financial assets to present the net carrying 
value at the amount expected to be collected through the expected maturity date of such investments. The expense for loan loss 
and other investment reserves is the charge to earnings to adjust the allowance for loan losses to the appropriate level. Amounts 
are written off from the allowance when we de-recognize the related investment either as a result of a sale of the investment or 
acquisition of equity interests in the collateral.

The Company evaluates the amount expected to be collected based on current market and economic conditions, historical 
loss information, and reasonable and supportable forecasts.  The Company's assumptions are derived from both internal data 
and external data which may include, among others, governmental economic projections for the New York City Metropolitan 
area,  public  data  on  recent  transactions  and  filings  for  securitized  debt  instruments.  This  information  is  aggregated  by  asset 
class and adjusted for duration. Based on these inputs, loans are evaluated at the individual asset level. In certain instances, we 
may also use a probability-weighted model that considers the likelihood of multiple outcomes and the amount expected to be 
collected for each outcome.

The  evaluation  of  the  possible  credit  deterioration  associated  with  the  performance  and/or  value  of  the  underlying 
collateral  property  as  well  as  the  financial  and  operating  capability  of  the  borrower/sponsor  requires  significant  judgment, 
which include both asset level and market assumptions over the relevant time period. 

In addition, quarterly, the Company assigns each loan a risk rating. Based on a 3-point scale, loans are rated “1” through 
“3,” from lower risk to higher risk, which ratings are defined as follows: 1 - Low Risk Assets - Low probability of loss, 2 - 
Watch List Assets - Higher potential for loss, 3 - High Risk Assets - Loss more likely than not. Loans with risk ratings of 2 or 
above are evaluated to determine whether the expected  risk of loss is  appropriately captured through the combination of our 
expectations  of  current  conditions,  historical  loss  information  and  supportable  forecasts  described  above  or  whether  risk 
characteristics specific to the loan warrant the use of a probability-weighted model.

Financing investments that are classified as held for sale are carried at the expected amount to be collected or fair market 
value using available market information obtained through consultation with dealers or other originators of such investments as 
well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management 
may conclude not to sell an investment designated as held for sale. In such situations, the investment will be reclassified at its 
expected amount to be collected.

Other  financing  receivables  that  are  included  in  balance  sheet  line  items  other  than  the  Debt  and  preferred  equity 

investments line are also measured at the net amount expected to be collected.

SL Green Realty Corp. and SL Green Operating Partnership, L.P.

Notes to Consolidated Financial Statements (cont.)

December 31, 2023

Accrued interest receivable amounts related to these debt and preferred equity investment and other financing receivables 
are recorded at the net amount expected to be collected within Other assets in the consolidated balance sheets. Accrued interest 
receivables that are written off are recognized as an expense in loan loss and other investment reserves.

Rent Expense

Rent  expense  is  recognized  on  a  straight-line  basis  over  the  initial  term  of  the  lease.  The  excess  of  the  rent  expense 
recognized  over  the  amounts  contractually  due  pursuant  to  the  underlying  lease  is  included  in  the  lease  liability  -  operating 
leases on the consolidated balance sheets.

Underwriting Commissions and Costs

Underwriting  commissions  and  costs  incurred  in  connection  with  our  stock  offerings  are  reflected  as  a  reduction  of 

additional paid-in-capital.

Transaction Costs

Transaction costs for real estate asset acquisitions are capitalized to the investment basis, which is then subject to a 

purchase price allocation based on relative fair value. Transaction costs for business combinations or costs incurred on potential 
transactions that are not consummated are expensed as incurred.

Income Taxes

SL Green is taxed as a REIT under Section 856(c) of the Code. As a REIT, SL Green generally is not subject to Federal 
income tax. To maintain its qualification as a REIT, SL Green must distribute at least 90% of its REIT taxable income to its 
stockholders and meet certain other requirements. If SL Green fails to qualify as a REIT in any taxable year, SL Green will be 
subject to Federal income tax on its taxable income at regular corporate rates. SL Green may also be subject to certain state, 
local and franchise taxes. Under certain circumstances, Federal income and excise taxes may be due on its undistributed taxable 
income.

The Operating Partnership is a partnership and, as a result, all income and losses of the partnership are allocated to the 
partners for inclusion in their respective income tax returns. The only provision for income taxes included in the consolidated 
statements  of  operations  relates  to  the  Operating  Partnership’s  consolidated  taxable  REIT  subsidiaries.  The  Operating 
Partnership may also be subject to certain state, local and franchise taxes.

We have elected, and may elect in the future, to treat certain of our corporate subsidiaries as taxable REIT subsidiaries, or 
TRSs. In general, TRSs may perform non-customary services for the tenants of the Company, hold assets that we cannot hold 
directly and generally may engage in any real estate or non-real estate related business. The TRSs generate income, resulting in 
Federal, state and local corporate tax liability for these entities. SUMMIT is held in a TRS and pays Federal, state and local 
taxes.  During  the  years  ended  December  31,  2023,  2022  and  2021,  we  recorded  Federal,  state  and  local  tax  expense  for 
SUMMIT of $9.2 million, $2.6 million, and $1.0 million, respectively.

 During the years ended December 31, 2023, 2022 and 2021, we recorded Federal, state and local tax provisions of $8.2 
million, $3.7 million, and $2.8 million, respectively. For the year ended December 31, 2023, the Company paid distributions on 
its common stock of $3.25 per share which represented $0.00 per share of ordinary income and $3.25 per share of capital gains. 
For  the  year  ended  December  31,  2022,  the  Company  paid  distributions  on  its  common  stock  of  $6.17  per  share  which 
represented $2.56 per share of ordinary income, and $1.17 per share of capital gains. For the year ended December 31, 2021, 
the Company paid distributions on its common stock of $8.09 per share which represented $0.50 per share of ordinary income 
and $5.92 per share of capital gains.

We follow a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise 
concludes  that  a  tax  position,  based  solely  on  its  technical  merits,  is  more-likely-than-not  to  be  sustained  upon  examination. 
Measurement  (step  two)  determines  the  amount  of  benefit  that  is  more-likely-than-not  to  be  realized  upon  settlement. 
Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a 
tax  position  no  longer  meets  the  more-likely-than-not  threshold  of  being  sustained.  The  use  of  a  valuation  allowance  as  a 
substitute for derecognition of tax positions is prohibited.

Stock Based Employee Compensation Plans

We have a stock-based employee compensation plan, described more fully in Note 14, "Share-based Compensation."

For  share-based  awards  with  a  performance  or  market  measure,  we  recognize  compensation  cost  over  the  requisite 
service  period,  using  the  accelerated  attribution  expense  method.  The  requisite  service  period  begins  on  the  date  the 

compensation  committee  of  our  Board  of  Directors  authorizes  the  award,  adopts  any  relevant  performance  measures  and 

communicates  the  award  to  the  employees.  For  programs  with  awards  that  vest  based  on  the  achievement  of  a  performance 

condition or market condition, we determine whether it is probable that the performance condition will be met, and estimate 

compensation cost based on the fair value of the award at the applicable award date estimated using a binomial model or market 

quotes.  For  share-based  awards  for  which  there  is  no  pre-established  performance  measure,  we  recognize  compensation  cost 

over the service vesting period, which represents the requisite service period, on a straight-line basis. In accordance with the 

provisions of our share-based incentive compensation plans, we accept the return of shares of the Company's common stock, at 

the current quoted market price, from certain key employees to satisfy minimum statutory tax-withholding requirements related 

to shares that vested during the period.

Awards  can  also  be  made  in  the  form  of  a  separate  series  of  units  of  limited  partnership  interest  in  the  Operating 

Partnership  called  long-term  incentive  plan  units,  or  LTIP  units.  LTIP  units,  which  can  be  granted  either  as  free-standing 

awards or in tandem with other awards under our stock incentive plan, are valued by reference to the value of the Company's 

common  stock  at  the  time  of  grant  and  are  subject  to  such  conditions  and  restrictions  as  the  compensation  committee  of  the 

Company's  board  of  directors  may  determine,  including  continued  employment  or  service,  computation  of  financial  metrics 

and/or achievement of pre-established performance goals and objectives.

The  Company's  stock  options  are  recorded  at  fair  value  at  the  time  of  issuance.  Fair  value  of  the  stock  options  is 

determined using the Black-Scholes option pricing model. The Black-Scholes model was developed for use in estimating the 

fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models 

require  the  input  of  highly  subjective  assumptions  including  the  expected  stock  price  volatility.  Because  our  plan  has 

characteristics significantly different from those of traded options and because changes in the subjective input assumptions can 

materially affect the fair value estimate, in our opinion, the existing models do not necessarily provide a reliable single measure 

of the fair value of the employee stock options.

Compensation cost for stock options, if any, is recognized over the vesting period of the award. Our policy is to grant 

options with an exercise price equal to the quoted closing market price of the Company's common stock on either the grant date 

or the date immediately preceding the grant date. Awards of stock or restricted stock are expensed as compensation over the 

benefit period based on the fair value of the stock on the grant date.

Derivative Instruments

In the normal course of business, we use a variety of commonly used derivative instruments, including, but not limited to, 

interest rate swaps, caps, collars and floors, to manage interest rate risk. Effectiveness is essential for those derivatives that we 

intend  to  qualify  for  hedge  accounting.  Some  derivative  instruments  are  associated  with  an  anticipated  transaction.  In  those 

cases, hedge effectiveness criteria also require that it be probable that the underlying transaction occurs. Instruments that meet 

these hedging criteria are formally designated as hedges at the inception of the derivative contract.

To determine the fair values of derivative instruments, we use a variety of methods and assumptions that are based on 

market  conditions  and  risks  existing  at  each  balance  sheet  date.  For  the  majority  of  financial  instruments  including  most 

derivatives,  long-term  investments  and  long-term  debt,  standard  market  conventions  and  techniques  such  as  discounted  cash 

flow analysis, option pricing models, replacement cost, and termination cost are used to determine fair value. All methods of 

assessing fair value result in a general approximation of value, and such value may never actually be realized.

In the normal course of business, we are exposed to the effect of interest rate changes and limit these risks by following 

established  risk  management  policies  and  procedures  including  the  use  of  derivatives.  To  address  exposure  to  interest  rates, 

derivatives  are  used  primarily  to  fix  the  rate  on  debt  based  on  floating-rate  indices  and  manage  the  cost  of  borrowing 

obligations.

We  use  a  variety  of  conventional  derivative  products.  These  derivatives  include,  but  are  not  limited  to,  interest  rate 

swaps,  caps,  collars  and  floors.  We  expressly  prohibit  the  use  of  unconventional  derivative  instruments  and  using  derivative 

instruments for trading or speculative purposes. Further, we have a policy of only entering into contracts with major financial 

institutions based upon their credit ratings and other factors.

We  may  employ  swaps,  forwards  or  purchased  options  to  hedge  qualifying  forecasted  transactions.  Gains  and  losses 

related to these transactions are deferred and recognized in net income as interest expense in the same period or periods that the 

underlying transaction occurs, expires or is otherwise terminated.

Hedges that are reported at fair value and presented on the balance sheet could be characterized as cash flow hedges or 

fair value hedges. Interest rate caps and collars are examples of cash flow hedges. Cash flow hedges address the risk associated

with  future  cash  flows  of  interest  payments.  For  all  hedges  held  by  us  that  meet  the  hedging  objectives  established  by  our 
corporate policy governing interest rate risk management, no net gains or losses were reported in earnings. The changes in fair 
value of derivative instruments designated as hedge instruments are reflected in accumulated other comprehensive income. For 
derivative instruments not designated as hedging instruments, the gain or loss, resulting from the change in the estimated fair 
value of the derivative instruments, is recognized in current earnings during the period of change.

Earnings per Share of the Company

The  Company  presents  both  basic  and  diluted  earnings  per  share  ("EPS")  using  the  two-class  method,  which  is  an 
earnings  allocation  formula  that  determines  EPS  for  common  stock  and  any  participating  securities  according  to  dividends 
declared  (whether  paid  or  unpaid).  Under  the  two-class  method,  basic  EPS  is  computed  by  dividing  the  income  available  to 
common stockholders by the weighted-average number of common stock shares outstanding for the period. Basic EPS includes 
participating  securities,  consisting  of  unvested  restricted  stock  that  receive  nonforfeitable  dividends  similar  to  shares  of 
common stock. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock 
were  exercised  or  converted  into  common  stock,  where  such  exercise  or  conversion  would  result  in  a  lower  EPS  amount. 
Diluted EPS also includes units of limited partnership interest. The dilutive effect of stock options is reflected in the weighted 
average diluted outstanding shares calculation by application of the treasury stock method.

Earnings per Unit of the Operating Partnership

Certain prior year balances have been reclassified to conform to our current year presentation.

The Operating Partnership presents both basic and diluted earnings per unit ("EPU") using the two-class method, which is 
an earnings allocation formula that determines EPU for common units and any participating securities according to dividends 
declared  (whether  paid  or  unpaid).  Under  the  two-class  method,  basic  EPU  is  computed  by  dividing  the  income  available  to 
common  unitholders  by  the  weighted-average  number  of  common  units  outstanding  for  the  period.  Basic  EPU  includes 
participating securities, consisting of unvested restricted units that receive nonforfeitable dividends similar to shares of common 
units. Diluted EPU reflects the potential dilution that could occur if securities or other contracts to issue common units were 
exercised or converted into common units, where such exercise or conversion would result in a lower EPU amount. The dilutive 
effect of unit  options  is  reflected  in the weighted  average diluted outstanding units calculation  by  application of  the  treasury 
stock method.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the  financial  statements  and 
accompanying notes. Actual results could differ from those estimates.

Concentrations of Credit Risk

Financial  instruments  that  potentially  subject  us  to  concentrations  of  credit  risk  consist  primarily  of  cash  investments, 
debt  and  preferred  equity  investments  and  accounts  receivable.  We  place  our  cash  investments  with  high  quality  financial 
institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt 
and Preferred Equity Investments." 

We  perform  initial  and  ongoing  evaluations  of  the  credit  quality  of  our  tenants  and  require  most  tenants  to  provide 
security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value 
of  a  tenant's  lease  obligation,  they  are  a  measure  of  good  faith  and  a  potential  source  of  funds  to  offset  the  economic  costs 
associated with lost revenue from that tenant and the costs associated with re-tenanting a space. The properties in our real estate 
portfolio are located in the New York metropolitan area, principally in Manhattan. Our tenants operate in various industries. 
Other than one tenant, Paramount Global  (formerly ViacomCBS Inc.),  which  accounted for  5.9%  of our share of annualized 
cash rent as of December 31, 2023, no other tenant in our portfolio accounted for more than 5.0% of our share of annualized 
cash rent, including our share of joint venture annualized cash rent, as of December 31, 2023.

For  the  years  ended  December  31,  2023,  2022,  and  2021,  the  following  properties  contributed  more  than  5.0%  of  our 

annualized cash rent from office properties, including our share of annualized cash rent from joint venture office properties:

Reclassification

As of December 31, 2023, the SUMMIT meets the criteria of a reportable operating segment pursuant to the guidance in 

ASC 280. Accordingly, we reclassified SUMMIT Operator revenue, SUMMIT Operator expenses, and SUMMIT Operator tax 

expense  to  separate  financial  statement  line  items  in  our  consolidated  statements  of  operations.  These  items  were  previously 

presented on a net basis in Other income. Additionally, the depreciation and amortization of SUMMIT assets are included in 

Depreciation  and  amortization  in  our  consolidated  statements  of  operations.  Prior  period  balances  have  been  reclassified  to 

conform to the current period presentation. 

Accounting Standards Updates

In  December  2023,  the  FASB  issued  ASU  No.  2023-09  Income  Taxes  (Topic  740)  -  Improvements  to  Income  Tax 

Disclosures.  The  objective  of  the  amendments  in  ASU  2023-09  related  to  the  rate  reconciliation  and  income  taxes  paid 

disclosures are to improve transparency of income tax disclosures by requiring consistent categories and greater disaggregation 

of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. The amendment will require that 

public entities on an annual basis disclose specific categories in the rate reconciliation and provide additional information for 

reconciling  items  that  meet  a  quantitative  threshold.  Additionally,  the  amendment  will  require  that  all  entities  disclose  on  an 

annual  basis  the  amount  of  taxes  paid  (net  of  refunds  received)  disaggregated  by  federal,  state  and  foreign  taxes  as  well  as  

disaggregated by individual jurisdictions that meet a quantitative threshold. ASU 2023-09 is effective prospectively for annual 

periods  beginning  after  December  15,  2024.  Early  adoption  and  retrospective  application  is  permitted.  We  are  currently 

evaluating the impact of the adoption of ASU 2023-09 on our consolidated financial statements, but do not believe the adoption 

of this standard will have a material impact on our consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable 

Segment  Disclosures.  ASU  2023-07  amends  the  reportable  segment  disclosure  requirements  to  enhance  disclosures  about 

significant  segment  expenses.  The  objective  of  the  amendment  is  to  improve  financial  reporting  by  requiring  disclosure  of 

incremental  segment  information  on  an  annual  and  interim  basis  for  all  public  entities  to  enable  investors  to  develop  more 

decision-useful  financial  analyses.  The  amendment  will  require  that  a  public  entity  disclose,  on  an  annual  and  interim  basis, 

significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within 

each reported measure of segment profit or loss (collectively referred to as the "significant expense principle"). Additionally, 

the amendment will require an entity to disclose an amount for "other segment items" by reportable segment and a description 

of its composition as well as require annual disclosures about a reportable segment's profit or loss and assets currently required 

by  Topic  280  in  interim  periods.  Lastly,  the  amendment  will  require  a  public  entity  to  disclose  the  title  and  position  of  the 

CODM  and  an  explanation  of  how  the  CODM  uses  the  reported  measures  of  segment  profit  or  loss  in  assessing  segment 

performance and deciding to allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, 

and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and should be applied 

retrospectively to all prior periods presented in the financial statements. We are currently evaluating the impact of the adoption 

of ASU 2023-07 on our consolidated financial statements, but do not believe the adoption of this standard will have a material 

impact on our consolidated financial statements.

with  future  cash  flows  of  interest  payments.  For  all  hedges  held  by  us  that  meet  the  hedging  objectives  established  by  our 

corporate policy governing interest rate risk management, no net gains or losses were reported in earnings. The changes in fair 

value of derivative instruments designated as hedge instruments are reflected in accumulated other comprehensive income. For 

derivative instruments not designated as hedging instruments, the gain or loss, resulting from the change in the estimated fair 

value of the derivative instruments, is recognized in current earnings during the period of change.

Earnings per Share of the Company

The  Company  presents  both  basic  and  diluted  earnings  per  share  ("EPS")  using  the  two-class  method,  which  is  an 

earnings  allocation  formula  that  determines  EPS  for  common  stock  and  any  participating  securities  according  to  dividends 

declared  (whether  paid  or  unpaid).  Under  the  two-class  method,  basic  EPS  is  computed  by  dividing  the  income  available  to 

common stockholders by the weighted-average number of common stock shares outstanding for the period. Basic EPS includes 

participating  securities,  consisting  of  unvested  restricted  stock  that  receive  nonforfeitable  dividends  similar  to  shares  of 

common stock. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock 

were  exercised  or  converted  into  common  stock,  where  such  exercise  or  conversion  would  result  in  a  lower  EPS  amount. 

Diluted EPS also includes units of limited partnership interest. The dilutive effect of stock options is reflected in the weighted 

average diluted outstanding shares calculation by application of the treasury stock method.

The Operating Partnership presents both basic and diluted earnings per unit ("EPU") using the two-class method, which is 

an earnings allocation formula that determines EPU for common units and any participating securities according to dividends 

declared  (whether  paid  or  unpaid).  Under  the  two-class  method,  basic  EPU  is  computed  by  dividing  the  income  available  to 

common  unitholders  by  the  weighted-average  number  of  common  units  outstanding  for  the  period.  Basic  EPU  includes 

participating securities, consisting of unvested restricted units that receive nonforfeitable dividends similar to shares of common 

units. Diluted EPU reflects the potential dilution that could occur if securities or other contracts to issue common units were 

exercised or converted into common units, where such exercise or conversion would result in a lower EPU amount. The dilutive 

effect of unit  options is  reflected  in  the weighted  average diluted outstanding units calculation  by  application of  the  treasury 

stock method.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 

requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the  financial  statements  and 

accompanying notes. Actual results could differ from those estimates.

Concentrations of Credit Risk

Financial  instruments  that  potentially  subject  us  to  concentrations  of  credit  risk  consist  primarily  of  cash  investments, 

debt  and  preferred  equity  investments  and  accounts  receivable.  We  place  our  cash  investments  with  high  quality  financial 

institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt 

and Preferred Equity Investments." 

We  perform  initial  and  ongoing  evaluations  of  the  credit  quality  of  our  tenants  and  require  most  tenants  to  provide 

security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value 

of  a  tenant's  lease  obligation,  they  are  a  measure  of  good  faith  and  a  potential  source  of  funds  to  offset  the  economic  costs 

associated with lost revenue from that tenant and the costs associated with re-tenanting a space. The properties in our real estate 

portfolio are located in the New York metropolitan area, principally in Manhattan. Our tenants operate in various industries. 

Other than one tenant, Paramount Global  (formerly ViacomCBS Inc.),  which  accounted for  5.9%  of our share  of annualized 

cash rent as of December 31, 2023, no other tenant in our portfolio accounted for more than 5.0% of our share of annualized 

cash rent, including our share of joint venture annualized cash rent, as of December 31, 2023.

For  the  years  ended  December  31,  2023,  2022,  and  2021,  the  following  properties  contributed  more  than  5.0%  of  our 

annualized cash rent from office properties, including our share of annualized cash rent from joint venture office properties:

On October 31, 2021, HNA, through an affiliated entity, filed for Chapter 11 bankruptcy protection on account of its investment in 245 Park Avenue, 

together with another asset in Chicago. On July 8, 2022, certain of the debtors and affiliates of SL Green entered into a Plan Sponsorship and Investment 

Agreement  (the  "Plan").  Since  the  debtors  did  not  receive  any  qualifying  bids  for  the  property  and  the  Plan  was  confirmed,  SL  Green  acquired  full 

ownership and control of the property in September 2022, at which time our outstanding preferred equity and accrued interest balance were credited to 

our equity investment in the property. We recorded the assets acquired and liabilities assumed at fair value. See Note 16, "Fair Value Measurements."

In  January  2021,  pursuant  to  the  partnership  documents  of  our  885  Third  Avenue  investment,  certain  participating  rights  of  the  common  member 

expired. As a result, it was determined that this investment is a VIE in which we are the primary beneficiary, and the investment was consolidated in our 

financial  statements.  Upon  consolidating  the  entity,  the  assets  and  liabilities  of  the  entity  were  recorded  at  fair  value.  Prior  to  January  2021,  the 

investment was accounted for under the equity method. See Note 6, "Investments in Unconsolidated Joint Ventures."

In April 2021, the Company exercised its option to acquire the fee interest in the property from the ground lessor and the Company acquired the fee 

interest in June 2021. The Company held the leasehold interest in the property prior to exercising its option.

In September 2021, the Company was the successful bidder for the fee interest in 690 Madison Avenue at the foreclosure of the asset. The property 

previously served as collateral for a debt and preferred equity investment. We recorded the assets acquired and liabilities assumed at fair value.

In  August  2023,  the  FASB  issued  ASU  No.  2023-05  Business  Combinations  -  Joint  Venture  Formations  (Subtopic 
805-60) Recognition and Initial Measurement. ASU 2023-05 addresses the accounting for contributions made to a joint venture, 
upon formation, in a joint venture's separate financial statements. The objectives of the amendments are to provide decision-
useful information to investors and other allocators of capital in a joint venture's financial statements and reduce diversity in 
practice.  The  amendments  require  that  a  joint  venture  apply  the  following  key  adaptations  from  the  business  combinations 
guidance upon formation: (i) a joint venture is the formation of a new entity without an accounting acquirer, (ii) a joint venture 
measures its identifiable net assets and goodwill, if any, at the formation date, (iii) initial measurement of a joint venture's total 
net  assets  is  equal  to  the  fair  value  of  100  percent  of  the  joint  venture's  equity,  and  (iv)  a  joint  venture  provides  relevant 
disclosures. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 
2025,  with  early  adoption  permitted  in  any  interim  or  annual  period  in  which  financial  statements  have  not  yet  been  issued, 
either  prospectively  or  retrospectively.  We  are  currently  evaluating  the  impact  of  the  adoption  of  ASU  2023-05  on  our 
consolidated  financial  statements,  but  do  not  believe  the  adoption  of  this  standard  will  have  a  material  impact  on  our 
consolidated financial statements.

In  March  2022,  the  FASB  issued  ASU  No.  2022-02  Financial  Instruments  -  Credit  Losses  (Topic  326)  Troubled  Debt 
Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the troubled debt restructuring recognition and measurement 
guidance and, instead, requires that an entity evaluate whether the modification represents a new loan or a continuation of an 
existing  loan.  The  amendments  enhance  existing  disclosure  requirements  and  introduce  new  requirements  related  to  certain 
modifications  of  receivables  made  to  borrowers  experiencing  financial  difficulties.  Additionally,  ASU  2022-02  requires  an 
entity to disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases 
within  the  scope  of  Subtopic  326-20.  Gross  write-off  information  must  be  included  in  the  vintage  disclosures  required  for 
entities  in  accordance  with  Subtopic  326-20,  which  requires  that  an  entity  disclose  the  amortized  cost  basis  of  financing 
receivables by credit-quality indicator and class of financing receivable by year of origination. ASU 2022-02 is effective for 
reporting periods beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption 
permitted.  The  Company  adopted  this  guidance  on  January  1,  2023  and  it  did  not  have  a  material  impact  on  the  Company's 
consolidated financial statements.

In  July  2021,  the  FASB  issued  ASU  No.  2021-05  Leases  (Topic  842)  Lessors  -  Certain  Leases  with  Variable  Lease 
Payments. ASU 2021-05 amends the lease classification requirements for lessors when classifying and accounting for a lease 
with variable lease payments that do not depend on a reference rate index or a rate. The update provides criteria, that if met, the 
lease  would  be  classified  and  accounted  for  as  an  operating  lease.  ASU  2021-05  is  effective  for  reporting  periods  beginning 
after December 15, 2021. The Company adopted this guidance on January 1, 2022 and it did not have a material impact on the 
Company's consolidated financial statements.

In August 2020, the FASB issued Accounting Standard Update, or "ASU," No. 2020-06 Debt - Debt with Conversion and 
Other  Options  (Subtopic  470-20)  and  Derivatives  and  Hedging  -  Contracts  in  Entity's  Own  Equity  (Subtopic  815-40).  ASU 
2020-06  simplifies  the  accounting  for  convertible  instruments  by  reducing  the  number  of  accounting  models  for  convertible 
debt instruments and convertible preferred stock, removes certain settlement conditions that are required for equity contracts to 
qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. ASU 
2020-06 is effective for reporting periods beginning after December 15, 2021. The Company adopted this guidance on January 
1, 2022 and it did not have a material impact on the Company's consolidated financial statements.

In  March  2020,  the  FASB  issued  ASU  No.  2020-04  Reference  Rate  Reform  (Topic  848)  Facilitation  of  the  Effects  of 
Reference  Rate  Reform  on  Financial  Reporting  and  then  in  January  2021,  the  FASB  issued  ASU  No.  2021-01.  The 
amendments  provide  practical  expedients  for  reference  rate  reform  related  activities  that  impact  debt,  leases,  derivatives  and 
other contracts. The guidance is optional and is effective between March 12, 2020 and December 31, 2024, which was extended 
from the original sunset date of December 31, 2022 when the FASB issued ASU No. 2022-06 in December 2022. The guidance 
may  be  elected  over  time  as  reference  rate  reform  activities  occur.  During  the  first  quarter  of  2020,  the  Company  elected  to 
apply  the  hedge  accounting  expedients  related  to  probability  and  the  assessments  of  effectiveness  for  future  LIBOR-indexed 
cash  flows  to  assume  that  the  index  upon  which  future  hedged  transactions  will  be  based  matches  the  index  on  the 
corresponding  derivatives.  Application  of  these  expedients  preserves  the  presentation  of  derivatives  consistent  with  past 
presentation. The impact of this guidance did not have a material impact on the Company's consolidated financial statements.

In  January  2021,  pursuant  to  the  partnership  documents  of  our  885  Third  Avenue  investment,  certain  participating  rights  of  the  common  member 
expired. As a result, it was determined that this investment is a VIE in which we are the primary beneficiary, and the investment was consolidated in our 
financial  statements.  Upon  consolidating  the  entity,  the  assets  and  liabilities  of  the  entity  were  recorded  at  fair  value.  Prior  to  January  2021,  the 
investment was accounted for under the equity method. See Note 6, "Investments in Unconsolidated Joint Ventures."
In April 2021, the Company exercised its option to acquire the fee interest in the property from the ground lessor and the Company acquired the fee 
interest in June 2021. The Company held the leasehold interest in the property prior to exercising its option.
In September 2021, the Company was the successful bidder for the fee interest in 690 Madison Avenue at the foreclosure of the asset. The property 
previously served as collateral for a debt and preferred equity investment. We recorded the assets acquired and liabilities assumed at fair value. 

805-60) Recognition and Initial Measurement. ASU 2023-05 addresses the accounting for contributions made to a joint venture, 

upon formation, in a joint venture's separate financial statements. The objectives of the amendments are to provide decision-

useful information to investors and other allocators of capital in a joint venture's financial statements and reduce diversity in 

practice.  The  amendments  require  that  a  joint  venture  apply  the  following  key  adaptations  from  the  business  combinations 

guidance upon formation: (i) a joint venture is the formation of a new entity without an accounting acquirer, (ii) a joint venture 

measures its identifiable net assets and goodwill, if any, at the formation date, (iii) initial measurement of a joint venture's total 

net  assets  is  equal  to  the  fair  value  of  100  percent  of  the  joint  venture's  equity,  and  (iv)  a  joint  venture  provides  relevant 

disclosures. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 

2025,  with  early  adoption  permitted  in  any  interim  or  annual  period  in  which  financial  statements  have  not  yet  been  issued, 

either  prospectively  or  retrospectively.  We  are  currently  evaluating  the  impact  of  the  adoption  of  ASU  2023-05  on  our 

consolidated  financial  statements,  but  do  not  believe  the  adoption  of  this  standard  will  have  a  material  impact  on  our 

consolidated financial statements.

In  March  2022,  the  FASB  issued  ASU  No.  2022-02  Financial  Instruments  -  Credit  Losses  (Topic  326)  Troubled  Debt 

Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the troubled debt restructuring recognition and measurement 

guidance and, instead, requires that an entity evaluate whether the modification represents a new loan or a continuation of an 

existing  loan.  The  amendments  enhance  existing  disclosure  requirements  and  introduce  new  requirements  related  to  certain 

modifications  of  receivables  made  to  borrowers  experiencing  financial  difficulties.  Additionally,  ASU  2022-02  requires  an 

entity to disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases 

within  the  scope  of  Subtopic  326-20.  Gross  write-off  information  must  be  included  in  the  vintage  disclosures  required  for 

entities  in  accordance  with  Subtopic  326-20,  which  requires  that  an  entity  disclose  the  amortized  cost  basis  of  financing 

receivables by credit-quality indicator and class of financing receivable by year of origination. ASU 2022-02 is effective for 

reporting periods beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption 

permitted.  The  Company  adopted  this  guidance  on  January  1,  2023  and  it  did  not  have  a  material  impact  on  the  Company's 

consolidated financial statements.

In  July  2021,  the  FASB  issued  ASU  No.  2021-05  Leases  (Topic  842)  Lessors  -  Certain  Leases  with  Variable  Lease 

Payments. ASU 2021-05 amends the lease classification requirements for lessors when classifying and accounting for a lease 

with variable lease payments that do not depend on a reference rate index or a rate. The update provides criteria, that if met, the 

lease  would  be  classified  and  accounted  for  as  an  operating  lease.  ASU  2021-05  is  effective  for  reporting  periods  beginning 

after December 15, 2021. The Company adopted this guidance on January 1, 2022 and it did not have a material impact on the 

Company's consolidated financial statements.

In August 2020, the FASB issued Accounting Standard Update, or "ASU," No. 2020-06 Debt - Debt with Conversion and 

Other  Options  (Subtopic  470-20)  and  Derivatives  and  Hedging  -  Contracts  in  Entity's  Own  Equity  (Subtopic  815-40).  ASU 

2020-06  simplifies  the  accounting  for  convertible  instruments  by  reducing  the  number  of  accounting  models  for  convertible 

debt instruments and convertible preferred stock, removes certain settlement conditions that are required for equity contracts to 

qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. ASU 

2020-06 is effective for reporting periods beginning after December 15, 2021. The Company adopted this guidance on January 

1, 2022 and it did not have a material impact on the Company's consolidated financial statements.

In  March  2020,  the  FASB  issued  ASU  No.  2020-04  Reference  Rate  Reform  (Topic  848)  Facilitation  of  the  Effects  of 

Reference  Rate  Reform  on  Financial  Reporting  and  then  in  January  2021,  the  FASB  issued  ASU  No.  2021-01.  The 

amendments  provide  practical  expedients  for  reference  rate  reform  related  activities  that  impact  debt,  leases,  derivatives  and 

other contracts. The guidance is optional and is effective between March 12, 2020 and December 31, 2024, which was extended 

from the original sunset date of December 31, 2022 when the FASB issued ASU No. 2022-06 in December 2022. The guidance 

may  be  elected  over  time  as  reference  rate  reform  activities  occur.  During  the  first  quarter  of  2020,  the  Company  elected  to 

apply  the  hedge  accounting  expedients  related  to  probability  and  the  assessments  of  effectiveness  for  future  LIBOR-indexed 

cash  flows  to  assume  that  the  index  upon  which  future  hedged  transactions  will  be  based  matches  the  index  on  the 

corresponding  derivatives.  Application  of  these  expedients  preserves  the  presentation  of  derivatives  consistent  with  past 

presentation. The impact of this guidance did not have a material impact on the Company's consolidated financial statements.

Sales price represents the gross sales price for a property or the gross asset valuation for interests in a property.
The  (losses)  gains  on  sale  are  net  of  $11.3  million,  $11.2  million,  and  $13.7  million  of  employee  compensation  accrued  in  connection  with  the 
realization of the investment dispositions during the years ended December 31, 2023, 2022, and 2021, respectively. Additionally, amounts do not include 
adjustments for expenses recorded in subsequent periods.
In June 2023, the Company sold a 49.9% interest, which resulted in the Company no longer retaining a controlling interest in the entity, as defined in 
ASC 810, and deconsolidation of the 50.1% interest we retained. We recorded our retained investment at fair value which resulted in the recognition of a 
fair value adjustment of ($17.0 million) that is reflected in the Company's consolidated statements of operations within Purchase price and other fair 
value adjustments. See Note 6, "Investments in Unconsolidated Joint Venture" and Note 16, " Fair Value Measurements."
In December 2022, the Company sold 414,317 square feet of office leasehold condominium units at the property. The Company retained the remaining 
218,796 square feet of the building.
In July 2021, the Company sold a 49.9% interest, which resulted in the Company no longer retaining a controlling interest in the entity, as defined in 
ASC 810, and the deconsolidation of the 51.0% interest we retained. We recorded our investment at fair value which resulted in the recognition of a fair 
value adjustment of $206.8 million, which is reflected in the Company's consolidated statements of operations within Purchase price and other fair value 
adjustments. See Note 6, "Investments in Unconsolidated Joint Ventures."
In March 2021, the property was foreclosed by the lender.
Disposition resulted from the ground lessee exercising its purchase option under a ground lease arrangement.

Year in which the investment was originated or acquired by us or in which a material modification occurred.
During the year ended December 31, 2023, we recognized a $6.9 million provision for loan loss related to an investment originated prior to 2021.
Includes two investments with a total carrying value of $49.8 million that are included in the Company's alternative strategy portfolio.

We  have  determined  that  we  have  one  portfolio  segment  of  financing  receivables  as  of  December  31,  2023  and  2022 

comprised of commercial real estate which is primarily recorded in debt and preferred equity investments.

Included  in  Other  assets  is  an  additional  amount  of  financing  receivables  representing  loans  to  joint  venture  partners 
totaling $8.8 million and $9.0 million as of December 31, 2023 and 2022, respectively. The Company recorded no provisions 
for loan losses related to these financing receivables for the years ended December 31, 2023 and 2022, respectively. All of these 
loans have a risk rating of 2 and were performing in accordance with their respective terms. One loan with a carrying value of 
$5.6 million was put on non-accrual in July 2020 and remains on non-accrual as of December 31, 2023. No investment income 
has been recognized subsequent to it being put on non-accrual.

In December 2023, following an assessment of the property and the investment for recoverability, the Company recorded a charge of $101.7 million, which 
is included in Depreciable real estate reserves and impairments in the consolidated statements of operations. In January 2024, the Company closed on the 
acquisition of interests in the joint venture that owns the leasehold interest for no consideration, which increases the Company's interest in the joint venture 
to  95.0%.  In  addition,  the  joint  venture  entered  into  an  agreement  to  satisfy  the  existing  $182.5  million  mortgage  on  the  property  for  a  net  payment  of 
$7.0 million, which closed in February 2024.
In 2020, the Company formed a joint venture, which then entered into a long-term sublease with the Company.
In 2020, the Company admitted partners to the One Madison Avenue development project, which resulted in the Company no longer retaining a controlling 
interest in the entity, as defined in ASC 810, and deconsolidation of our remaining 50.5% interest. We recorded our investment at fair value, which resulted 
in the recognition of a fair value adjustment of $187.5 million. The fair value of our investment was determined by the terms of the joint venture agreement 
governing  the  capitalization  of  the  project.  In  2021,  the  Company  admitted  an  additional  partner  to  the  development  project  with  the  partner's  indirect 
ownership  in  the  joint  venture  totaling  25.0%.  The  transaction  did  not  meet  sale  accounting  under  ASC  860  and,  as  a  result,  was  treated  as  a  secured 
borrowing for accounting purposes and is included in Other liabilities in our consolidated balance sheets at December 31, 2023 and 2022.
The 50.1% ownership interest reflected in this table is comprised of our 25.1% economic interest and a 25.0% economic interest held by a third-party. The 
third-party's  economic  interest  is  held  within  a  joint  venture  that  we  consolidate  and  recognize  in  Noncontrolling  interests  in  other  partnerships  on  our 
consolidated balance sheet. An additional third-party owns the remaining 49.9% economic interest in the property.
In June 2023, the Company sold a 49.9% interest, which resulted in the Company no longer retaining a controlling interest in the entity, as defined in ASC 
810,  and  deconsolidation  of  the  50.1%  interest  we  retained.  We  recorded  our  investment  at  fair  value  which  resulted  in  the  recognition  of  a  fair  value 
adjustment of ($17.0 million) during the year ended December 31, 2023. The fair value of our investment was determined by the terms of the joint venture 
agreement.
In September 2023, following a UCC foreclosure, the Company converted its previous mezzanine debt investments in the fee interest to a 90.43% ownership 
interest. See Note 5, "Debt and Preferred Equity Investments." In December 2023, together with its joint venture, the Company entered into a contract to sell 
the fee ownership in the property. In connection with this contract, the Company recorded a charge of $23.1 million, which is included in Depreciable real 
estate reserves and impairments in the consolidated statements of operations. This transaction is expected to close in the first quarter of 2024.

9. Corporate Indebtedness

2021 Credit Facility

In December 2021, we entered into an amended and restated credit facility, referred to as the 2021 credit facility, that was 
previously amended by the Company in November 2017, and was originally entered into by the Company in November 2012. 
As of December 31, 2023, the 2021 credit facility consisted of a $1.25 billion revolving credit facility, a $1.05 billion term loan 
(or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of May 15, 2026, May 15, 2027, 
and November 21, 2024, respectively. The revolving credit facility has two six-month as-of-right extension options to May 15, 
2027. We also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at 
any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by 
obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2023, the 2021 credit facility bore interest at a spread over adjusted Term SOFR plus 10 basis points 
with an interest period of one or three months, as we may elect, ranging from (i) 72.5 basis points to 140 basis points for loans 
under the revolving credit facility, (ii) 80 basis points to 160 basis points for loans under Term Loan A, and (iii) 85 basis points 
to 165 basis points for loans under Term Loan B, in each case based on the credit rating assigned to the senior unsecured long 
term indebtedness of the Company. In instances where there are either only two ratings available or where there are more than 
two and the difference between them is one rating category, the applicable rating shall be the highest rating. In instances where 
there are more than two ratings and the difference between the highest and the lowest is two or more rating categories, then the 
applicable rating used is the average of the highest two, rounded down if the average is not a recognized category.

As  of  December  31,  2023,  the  applicable  spread  over  adjusted  Term  SOFR  plus  10  basis  points  for  the  2021  credit 
facility was 140 basis points for the revolving credit facility, 160 basis points for Term Loan A, and 165 basis points for Term 
Loan  B.  We  are  required  to  pay  quarterly  in  arrears  a  12.5  to  30  basis  point  facility  fee  on  the  total  commitments  under  the 
revolving credit facility based on the credit rating assigned to the senior unsecured long-term indebtedness of the Company. As 
of December 31, 2023, the facility fee was 30 basis points.

As of December 31, 2023, we had $2.0 million of outstanding letters of credit, $560.0 million drawn under the revolving 
credit facility and $1.25 billion outstanding under the term loan facilities, with total undrawn capacity of $688.0 million under 
the 2021 credit facility. As of December 31, 2023 and December 31, 2022, the revolving credit facility had a carrying value of 
$554.8 million and $443.2 million, respectively, net of deferred financing costs. As of December 31, 2023 and December 31, 
2022, the term loan facilities had a carrying value of $1.2 billion and $1.2 billion, respectively, net of deferred financing costs.

The Company and the Operating Partnership are borrowers jointly and severally obligated under the 2021 credit facility.

The 2021 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

2022 Term Loan

In October 2022, we entered into a term loan agreement, referred to as the 2022 term loan. The 2022 term loan was repaid 
in full in September 2023. The 2022 term loan consisted of a $425.0 million term loan with a maturity date of October 6, 2023. 
The  2022  term  loan  had  one  six-month  as-of-right  extension  option  to  April  6,  2024.  We  also  had  an  option,  subject  to 
customary conditions, to increase the capacity of the 2022 term loan to $500.0 million on or before January 7, 2023 without the 
consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions. In 
January 2023, the 2022 term loan was increased by $25.0 million to $425.0 million. 

The  2022  term  loan  bore  interest  at  a  spread  over  adjusted  Term  SOFR  plus  10  basis  points,  ranging  from  100  basis 
points to 180 basis points, in each case based on the credit rating assigned to the senior unsecured long-term indebtedness of the 
Company. In instances where there were either only two ratings available or where there was more than two and the difference 
between them was one rating category, the applicable rating was the highest rating. In instances where there were more than 
two ratings and the difference between the highest and the lowest were two or more rating categories, then the applicable rating 
used was the average of the highest two, rounded down if the average was not a recognized category. As of December 31, 2022, 
the 2022 term loan had a carrying value of $398.2 million, net of deferred financing costs.

The terms of the 2021 credit facility and our senior unsecured notes include certain restrictions and covenants which may 

limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur 

liens  and  enter  into  negative  pledge  agreements  and  dispose  of  assets,  and  which  require  compliance  with  financial  ratios 

relating  to  the  maximum  ratio  of  total  indebtedness  to  total  asset  value,  a  minimum  ratio  of  EBITDA  to  fixed  charges,  a 

maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered 

asset value. The dividend restriction referred to above provides that, we will not during any time when a default is continuing, 

make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify 

as  a  REIT  for  Federal  income  tax  purposes.  As  of  December  31,  2023  and  2022,  we  were  in  compliance  with  all  such 

covenants.

Junior Subordinated Deferrable Interest Debentures

In  June  2005,  the  Company  and  the  Operating  Partnership  issued  $100.0  million  in  unsecured  trust  preferred  securities 

through  a  newly  formed  trust,  SL  Green  Capital  Trust  I,  or  the  Trust,  which  is  a  wholly-owned  subsidiary  of  the  Operating 

Partnership.  The  securities  mature  in  2035  and  bear  interest  at  a  floating  rate  of  26  basis  points  over  the  three-month  Term 

SOFR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises 

its  right  to  defer  such  payments.  The  Trust  preferred  securities  are  redeemable  at  the  option  of  the  Operating  Partnership,  in 

whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we 

are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance 

sheets and the related payments are classified as interest expense.

Principal Maturities

Combined  aggregate  principal  maturities  of  mortgages  and  other  loans  payable,  the  2021  credit  facility,  trust  preferred

facility was 140 basis points for the revolving credit facility, 160 basis points for Term Loan A, and 165 basis points for Term

The  2022  term  loan  had  one  six-month  as-of-right  extension  option  to  April  6,  2024.  We  also  had  an  option,  subject  to

make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify 
as  a  REIT  for  Federal  income  tax  purposes.  As  of  December  31,  2023  and  2022,  we  were  in  compliance  with  all  such 
covenants.

Junior Subordinated Deferrable Interest Debentures

In  June  2005,  the  Company  and  the  Operating  Partnership  issued  $100.0  million  in  unsecured  trust  preferred  securities 
through  a  newly  formed  trust,  SL  Green  Capital  Trust  I,  or  the  Trust,  which  is  a  wholly-owned  subsidiary  of  the  Operating 
Partnership.  The  securities  mature  in  2035  and  bear  interest  at  a  floating  rate  of  26  basis  points  over  the  three-month  Term 
SOFR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises 
its  right  to  defer  such  payments.  The  Trust  preferred  securities  are  redeemable  at  the  option  of  the  Operating  Partnership,  in 
whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we 
are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance 
sheets and the related payments are classified as interest expense.

Principal Maturities

Combined  aggregate  principal  maturities  of  mortgages  and  other  loans  payable,  the  2021  credit  facility,  trust  preferred

Cleaning/ Security/ Messenger and Restoration Services

Prior  to  2023,  Alliance  Building  Services,  or  Alliance,  and  its  affiliates,  which  provide  services  to  certain  properties 
owned by us, were previously partially owned by Gary Green, a son of Stephen L. Green, who serves as a member and as the 
chairman  emeritus  of  our  Board  of  Directors.  Alliance’s  affiliates  include  First  Quality  Maintenance,  L.P.,  or  First  Quality, 
Classic Security LLC, Bright Star Couriers LLC and Onyx Restoration Works, and provide cleaning, extermination, security, 
messenger,  and  restoration  services,  respectively.  In  addition,  First  Quality  has  the  non-exclusive  opportunity  to  provide 
cleaning  and  related  services  to  individual  tenants  at  our  properties  on  a  basis  separately  negotiated  with  any  tenant  seeking 
such additional services. The Service Corporation has entered into an arrangement with Alliance whereby it will receive a profit 
participation above a certain threshold for services provided by Alliance to certain tenants at certain buildings above the base 
services specified in their lease agreements.

Income  earned  from  the  profit  participation  prior  to  2023,  which  is  included  in  Other  income  on  the  consolidated 
statements of operations, was $1.4 million and $1.7 million for the years ended December 31, 2022 and 2021, respectively. We 
also  recorded  expenses,  inclusive  of  capitalized  expenses,  of  $8.6  million  and  $14.0  million  for  these  services  (excluding 
services provided directly to tenants) for the years ended December 31, 2022 and 2021, respectively.

One Vanderbilt Avenue Investment

Partnership.

Our  Chairman  and  CEO,  Marc  Holliday,  and  our  former  President,  Andrew  Mathias,  made  investments  in  our  One 
Vanderbilt project (inclusive of the property and SUMMIT One Vanderbilt), which entitles Mr. Holliday and Mr. Mathias to 
receive  approximately  1.27%  and  0.85%,  respectively,  on  account  of  the  property  and  1.92%  and  1.28%,  respectively,  on 
account of SUMMIT One Vanderbilt, of any profits realized by the Company from its One Vanderbilt project in excess of the 
Company's capital contributions. Mr. Holliday and Mr. Mathias paid $1.4 million and $1.0 million, respectively, which equaled 
the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an 
independent third party appraisal that we obtained.

Messrs. Holliday and Mathias have the right to tender their interests in the project upon stabilization (50% within three 
years after stabilization and 100% three years or more after stabilization). In addition, the agreement calls for us to repurchase 
these interests in the event of a sale of One Vanderbilt or a transactional change of control of the Company. We also have the 
right to repurchase these interests on the 7-year anniversary of the stabilization of the project or upon the occurrence of certain 
separation events prior to the stabilization of the project relating to each of Messrs. Holliday’s and Mathias’s continued service 
with us. The price paid upon a tender of the interests will equal the liquidation value of the interests at the time, with the value 
being based on the project's sale price, if applicable, or fair market value as determined by an independent third party appraiser. 
In  2022,  stabilization  of  the  property  (but  not  SUMMIT  One  Vanderbilt)  was  achieved.  Therefore,  Messrs.  Holiday  and 
Mathias exercised their rights to tender 50% of their interests in the property (but not SUMMIT One Vanderbilt) for liquidation 
values of $17.9 million and $11.9 million, respectively, which were paid in July 2022.

One Vanderbilt Avenue Leases

In  November  2018,  we  entered  into  a  lease  agreement  with  the  One  Vanderbilt  Avenue  joint  venture  covering  certain 
floors at the property. In March 2021, the lease commenced and we relocated our corporate headquarters to the leased space. 
For  the  years  ended  December  31,  2023  and  2022  we  recorded  $3.0  million  and  $3.0  million,  respectively,  of  rent  expense 
under the lease. Additionally, in June 2021, we, through a consolidated subsidiary, entered into a lease agreement with the One 
Vanderbilt  Avenue  joint  venture  for  SUMMIT  One  Vanderbilt,  which  commenced  operations  in  October  2021.  For  the  year

We have 9,200,000 shares of our 6.50% Series I Cumulative Redeemable Preferred Stock, or the Series I Preferred Stock, 

outstanding  with  a  mandatory  liquidation  preference  of  $25.00  per  share.  The  Series  I  Preferred  stockholders  receive  annual 

dividends  of  $1.625  per  share  paid  on  a  quarterly  basis  and  dividends  are  cumulative,  subject  to  certain  provisions.  We  are 

entitled to redeem the Series I Preferred Stock at any time, in whole or from time to time in part, at par for cash. In August 

2012, we received $221.9 million in net proceeds from the issuance of the Series I Preferred Stock, which were recorded net of 

underwriters'  discount  and  issuance  costs,  and  contributed  the  net  proceeds  to  the  Operating  Partnership  in  exchange  for 

9,200,000  units  of  6.50%  Series  I  Cumulative  Redeemable  Preferred  Units  of  limited  partnership  interest,  or  the  Series  I

Dividend Reinvestment and Stock Purchase Plan ("DRSPP")

In  February  2021,  the  Company  filed  a  registration  statement  with  the  SEC  for  our  dividend  reinvestment  and  stock

We  use  the  two-class  method  of  computing  earnings  per  share  (“EPS”),  which  is  an  earnings  allocation  formula  that 

determines EPS for common stock and any participating securities according to dividends declared (whether paid or unpaid). 

Under the two-class method, basic EPS is computed by dividing the income available to common stockholders by the weighted-

average number of common stock shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur 

from share equivalent activity.

Dividends are cumulative, subject to certain provisions.
Units are redeemable at any time at par for cash at the option of the unit holder unless otherwise specified.
If applicable, units are convertible into a number of common units of limited partnership interest in the Operating Partnership equal to (i) the liquidation 
preference plus accumulated and unpaid distributions on the conversion date divided by (ii) the amount shown in the table.
Issued  through  a  consolidated  subsidiary.  The  units  are  convertible  on  a  one-for-one  basis,  into  the  Series  B  Preferred  Units  of  limited  partnership 
interest, or the Subsidiary Series B Preferred Units. The Subsidiary Series B Preferred Units can be converted at any time, after July 15, 2024 at the 
option of the unitholder, into a number of common stock equal to 6.71348 shares of common stock for each Subsidiary Series B Preferred Unit. As such, 
no Subsidiary Series B Preferred Units have been issued as of December 31, 2023.
The Series V Preferred Units are redeemable at any time after January 1, 2025 at par for cash at the option of the unit holder.
The  Series  W  preferred  unit  was  issued  in  January  2020  in  exchange  for  the  then-outstanding  Series  O  preferred  unit.  The  holder  of  the  Series  W 
preferred unit is entitled to quarterly dividends in an amount calculated as (i) 1,350 multiplied by (ii) the current distribution per common unit of limited 
partnership in SL Green Operating Partnership. The holder has the right to require the Operating Partnership to repurchase the Series W unit for cash, or 
convert the Series W unit for Class B units, in each case at a price that is determined based on the closing price of the Company's common stock at the 
time such right is exercised. The unit's liquidation preference is the fair market value of the unit plus accrued distributions at the time of a liquidation 
event.

13. Partners' Capital of the Operating Partnership 

The  Company  is  the  sole  managing  general  partner  of  the  Operating  Partnership  and  as  of  December  31,  2023  owned 
64,726,253  general  and  limited  partnership  interests  in  the  Operating  Partnership  and  9,200,000  Series  I  Preferred  Units. 
Partnership  interests  in  the  Operating  Partnership  are  denominated  as  “common  units  of  limited  partnership  interest”  (also 
referred  to  as  “OP  Units”)  or  “preferred  units  of  limited  partnership  interest”  (also  referred  to  as  “Preferred  Units”).  All 
references to OP Units and Preferred Units outstanding exclude such units held by the Company. A holder of an OP Unit may 
present  such  OP  Unit  to  the  Operating  Partnership  for  redemption  at  any  time  (subject  to  restrictions  agreed  upon  at  the 
issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). 
Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit in exchange for the cash 
equal to the then value of a share of common stock of the Company, except that the Company may, at its election, in lieu of 
cash  redemption,  acquire  such  OP  Unit  for  one  share  of  common  stock.  Because  the  number  of  shares  of  common  stock 
outstanding at all times equals the number of OP Units that the Company owns, one share of common stock is generally the 
economic  equivalent  of  one  OP  Unit,  and  the  quarterly  distribution  that  may  be  paid  to  the  holder  of  an  OP  Unit  equals  the 
quarterly  dividend  that  may  be  paid  to  the  holder  of  a  share  of  common  stock.  Each  series  of  Preferred  Units  makes  a 
distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred 
Units may also be convertible into OP Units at the election of the holder thereof or the Company, subject to the terms of such 
Preferred Units.

Net income (loss) allocated to the preferred unitholders and common unitholders reflects their pro rata share of net income 

(loss) and distributions.

The  Operating  Partnership  has  excluded  1,273,417  common  unit  equivalents  from  the  diluted  units  outstanding  for  the 

years  ended  December  31,  2023.  The  Operating  Partnership  has  excluded  1,682,236  and  948,017  common  unit  equivalents 

from the diluted units outstanding for the years ended December 31, 2022 and 2021, respectively.

14. Share-based Compensation

We have share-based employee and director compensation plans. Our employees are compensated through the Operating 

Partnership. Under each plan, whenever the Company issues common or preferred stock, the Operating Partnership issues an 

equivalent number of units of limited partnership interest of a corresponding class to the Company.

The  Fifth  Amended  and  Restated  2005  Stock  Option  and  Incentive  Plan,  or  the  2005  Plan,  was  approved  by  the 

Company's  Board  of  Directors  in  April  2022  and  its  stockholders  in  June  2022  at  the  Company's  annual  meeting  of 

stockholders. The 2005 Plan authorizes the issuance of stock options, stock appreciation rights, unrestricted and restricted stock, 

phantom  shares,  dividend  equivalent  rights,  cash-based  awards  and  other  equity-based  awards.  Subject  to  adjustments  upon 

certain corporate transactions or events, awards with respect to up to a maximum of 32,210,000 fungible units may be granted 

under the 2005 Plan. Currently, different types of awards count against the limit on the number of fungible units differently, 

with (1) full-value awards (i.e., those that deliver the full value of the award upon vesting, such as restricted stock) counting as 

2.59 Fungible Units per share subject to such awards, (2) stock options, stock appreciation rights and other awards that do not 

deliver full value and expire five years from the date of grant counting as 0.84 fungible units per share subject to such awards, 

and (3) all other awards (e.g., 10-year stock options) counting as 1.0 fungible units per share subject to such awards. Awards

13. Partners' Capital of the Operating Partnership 

The  Company  is  the  sole  managing  general  partner  of  the  Operating  Partnership  and  as  of  December  31,  2023  owned 

64,726,253  general  and  limited  partnership  interests  in  the  Operating  Partnership  and  9,200,000  Series  I  Preferred  Units. 

Partnership  interests  in  the  Operating  Partnership  are  denominated  as  “common  units  of  limited  partnership  interest”  (also 

referred  to  as  “OP  Units”)  or  “preferred  units  of  limited  partnership  interest”  (also  referred  to  as  “Preferred  Units”).  All 

references to OP Units and Preferred Units outstanding exclude such units held by the Company. A holder of an OP Unit may 

present  such  OP  Unit  to  the  Operating  Partnership  for  redemption  at  any  time  (subject  to  restrictions  agreed  upon  at  the 

issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). 

Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit in exchange for the cash 

equal to the then value of a share of common stock of the Company, except that the Company may, at its election, in lieu of 

cash  redemption,  acquire  such  OP  Unit  for  one  share  of  common  stock.  Because  the  number  of  shares  of  common  stock 

outstanding at all times equals the number of OP Units that the Company owns, one share of common stock is generally the 

economic  equivalent  of  one  OP  Unit,  and  the  quarterly  distribution  that  may  be  paid  to  the  holder  of  an  OP  Unit  equals  the 

quarterly  dividend  that  may  be  paid  to  the  holder  of  a  share  of  common  stock.  Each  series  of  Preferred  Units  makes  a 

distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred 

Units may also be convertible into OP Units at the election of the holder thereof or the Company, subject to the terms of such

14. Share-based Compensation

We have share-based employee and director compensation plans. Our employees are compensated through the Operating 
Partnership. Under each plan, whenever the Company issues common or preferred stock, the Operating Partnership issues an 
equivalent number of units of limited partnership interest of a corresponding class to the Company.

The  Fifth  Amended  and  Restated  2005  Stock  Option  and  Incentive  Plan,  or  the  2005  Plan,  was  approved  by  the 
Company's  Board  of  Directors  in  April  2022  and  its  stockholders  in  June  2022  at  the  Company's  annual  meeting  of 
stockholders. The 2005 Plan authorizes the issuance of stock options, stock appreciation rights, unrestricted and restricted stock, 
phantom  shares,  dividend  equivalent  rights,  cash-based  awards  and  other  equity-based  awards.  Subject  to  adjustments  upon 
certain corporate transactions or events, awards with respect to up to a maximum of 32,210,000 fungible units may be granted 
under the 2005 Plan. Currently, different types of awards count against the limit on the number of fungible units differently, 
with (1) full-value awards (i.e., those that deliver the full value of the award upon vesting, such as restricted stock) counting as 
2.59 Fungible Units per share subject to such awards, (2) stock options, stock appreciation rights and other awards that do not 
deliver full value and expire five years from the date of grant counting as 0.84 fungible units per share subject to such awards, 
and (3) all other awards (e.g., 10-year stock options) counting as 1.0 fungible units per share subject to such awards. Awards

granted  under  the  2005  Plan  prior  to  the  approval  of  the  fifth  amendment  and  restatement  in  June  2022  continue  to  count 
against  the  fungible  unit  limit  based  on  the  ratios  that  were  in  effect  at  the  time  such  awards  were  granted,  which  may  be 
different than the current ratios. As a result, depending on the types of awards issued, the 2005 Plan may result in the issuance 
of more or less than 32,210,000 shares. If a stock option or other award granted under the 2005 Plan expires or terminates, the 
common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case 
may be, will again become available for the issuance of additional awards. Shares of our common stock distributed under the 
2005  Plan  may  be  treasury  shares  or  authorized  but  unissued  shares.  Currently,  unless  the  2005  Plan  has  been  previously 
terminated by the Company's Board of Directors, new awards may be granted under the 2005 Plan until June 1, 2032, which is 
the  tenth  anniversary  of  the  date  that  the  2005  Plan  was  most  recently  approved  by  the  Company's  stockholders.  As  of 
December  31,  2023,  3.9  million  fungible  units  were  available  for  issuance  under  the  2005  Plan  after  reserving  for  shares 
underlying outstanding restricted stock units, phantom stock units granted pursuant to our Non-Employee Directors' Deferral 
Program and LTIP Units.

Stock Options and Class O LTIP Units

Options are granted with an exercise price at the fair market value of the Company's common stock on the date of grant 
and, subject to employment, generally expire five years or ten years from the date of grant, are not transferable other than on 
death, and generally vest in one year to five years commencing one year from the date of grant. We have also granted Class O 
LTIP Units, which are a class of LTIP Units in the Operating Partnership structured to provide economics similar to those of 
stock options. Class O LTIP Units, once vested, may be converted, at the election of the holder, into a number of common units 
of the Operating Partnership per Class O LTIP Unit determined by the increase in value of a share of the Company’s common 
stock at the time of conversion over a participation threshold, which equals the fair market value of a share of the Company’s 
common stock at the time of grant. Class O LTIP Units are entitled to distributions, subject to vesting, equal per unit to 10% of 
the per unit distributions paid with respect to the common units of the Operating Partnership.

The fair value of each stock option or LTIP Unit granted is estimated on the date of grant using the Black-Scholes option 
pricing model based on historical information. There were no options granted during the years ended December 31, 2023, 2022, 
and 2021. 

A summary of the status of the Company's stock options as of December 31, 2023, 2022, and 2021 and changes during

The  remaining  weighted  average  contractual  life  of  the  options  outstanding  was  3.0  years  and  the  remaining  average

As of December 31, 2023, there was no unrecognized compensation cost related to unvested stock options.

Restricted Shares

Shares are granted to certain employees, including our executives, and vesting occurs upon the completion of a service 
period  or  our  meeting  established  financial  performance  criteria.  Vesting  occurs  at  rates  ranging  from  15%  to  35%  once 
performance criteria are reached.

A summary of the Company's restricted stock as of December 31, 2023, 2022, and 2021 and changes during the years

The  fair  value  of  restricted  stock  that  vested  during  the  years  ended  December  31,  2023,  2022,  and  2021  was  $10.2 

million, $9.7 million and $11.3 million, respectively. As of December 31, 2023, there was $20.2 million of total unrecognized 

compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 2.3 years.

We  granted  LTIP  Units,  which  include  bonus,  time-based  and  performance-based  awards,  with  a  fair  value  of  $38.1 

million and $45.0 million during the years ended December 31, 2023 and 2022, respectively. The grant date fair value of the 

LTIP Unit awards was calculated in accordance with ASC 718. A third-party consultant determined that the fair value of the 

LTIP Units has a discount to our common stock price. The discount was calculated by considering the inherent uncertainty that 

the  LTIP  Units  will  reach  parity  with  other  common  partnership  units  and  the  illiquidity  due  to  transfer  restrictions.  As  of 

December  31,  2023,  there  was  $27.1  million  of  total  unrecognized  compensation  expense  related  to  the  time-based  and 

performance-based awards, which is expected to be recognized over a weighted average period of 1.6 years. 

During the years ended December 31, 2023, 2022, and 2021, we recorded compensation expense related to bonus, time-

based and performance-based awards of $50.4 million, $43.5 million, and $41.9 million, respectively.

For the years ended December 31, 2023, 2022, and 2021, $1.4 million, $1.8 million, and $2.1 million, respectively, was 

capitalized  to  assets  associated  with  compensation  expense  related  to  our  long-term  compensation  plans,  restricted  stock  and 

stock options.

Deferred Compensation Plan for Directors

Under  our  Non-Employee  Director's  Deferral  Program,  which  commenced  July  2004,  the  Company's  non-employee 

directors may elect to defer up to 100% of their annual retainer fee, chairman fees, meeting fees and annual stock grant. Unless 

otherwise elected by a participant, fees deferred under the program shall be credited in the form of phantom stock units. The 

program provides that a director's phantom stock units generally will be settled in an equal number of shares of common stock 

upon the earlier of (i) the January 1 coincident with or the next following such director's termination of service from the Board 

of Directors or (ii) a change in control by us, as defined by the program. Phantom stock units are credited to each non-employee 

director  quarterly  using  the  closing  price  of  our  common  stock  on  the  first  business  day  of  the  respective  quarter.  Each 

participating  non-employee  director  is  also  credited  with  dividend  equivalents  or  phantom  stock  units  based  on  the  dividend 

rate for each quarter, which are either paid in cash currently or credited to the director’s account as additional phantom stock 

During the year ended December 31, 2023, 39,302 phantom stock units and 27,739 shares of common stock were issued 

to our Board of Directors. We recorded compensation expense of $2.7 million during the year ended December 31, 2023 related 

to the Deferred Compensation Plan. As of December 31, 2023, there were 230,295 phantom stock units outstanding pursuant to 

our Non-Employee Director's Deferral Program.

different than the current ratios. As a result, depending on the types of awards issued, the 2005 Plan may result in the issuance 

of more or less than 32,210,000 shares. If a stock option or other award granted under the 2005 Plan expires or terminates, the 

common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case 

may be, will again become available for the issuance of additional awards. Shares of our common stock distributed under the

compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 2.3 years.

We  granted  LTIP  Units,  which  include  bonus,  time-based  and  performance-based  awards,  with  a  fair  value  of  $38.1 
million and $45.0 million during the years ended December 31, 2023 and 2022, respectively. The grant date fair value of the 
LTIP Unit awards was calculated in accordance with ASC 718. A third-party consultant determined that the fair value of the 
LTIP Units has a discount to our common stock price. The discount was calculated by considering the inherent uncertainty that 
the  LTIP  Units  will  reach  parity  with  other  common  partnership  units  and  the  illiquidity  due  to  transfer  restrictions.  As  of 
December  31,  2023,  there  was  $27.1  million  of  total  unrecognized  compensation  expense  related  to  the  time-based  and 
performance-based awards, which is expected to be recognized over a weighted average period of 1.6 years. 

During the years ended December 31, 2023, 2022, and 2021, we recorded compensation expense related to bonus, time-

based and performance-based awards of $50.4 million, $43.5 million, and $41.9 million, respectively.

For the years ended December 31, 2023, 2022, and 2021, $1.4 million, $1.8 million, and $2.1 million, respectively, was 
capitalized  to  assets  associated  with  compensation  expense  related  to  our  long-term  compensation  plans,  restricted  stock  and 
stock options.

Deferred Compensation Plan for Directors

Under  our  Non-Employee  Director's  Deferral  Program,  which  commenced  July  2004,  the  Company's  non-employee 
directors may elect to defer up to 100% of their annual retainer fee, chairman fees, meeting fees and annual stock grant. Unless 
otherwise elected by a participant, fees deferred under the program shall be credited in the form of phantom stock units. The 
program provides that a director's phantom stock units generally will be settled in an equal number of shares of common stock 
upon the earlier of (i) the January 1 coincident with or the next following such director's termination of service from the Board 
of Directors or (ii) a change in control by us, as defined by the program. Phantom stock units are credited to each non-employee 
director  quarterly  using  the  closing  price  of  our  common  stock  on  the  first  business  day  of  the  respective  quarter.  Each 
participating  non-employee  director  is  also  credited  with  dividend  equivalents  or  phantom  stock  units  based  on  the  dividend 
rate for each quarter, which are either paid in cash currently or credited to the director’s account as additional phantom stock 
units.

During the year ended December 31, 2023, 39,302 phantom stock units and 27,739 shares of common stock were issued 
to our Board of Directors. We recorded compensation expense of $2.7 million during the year ended December 31, 2023 related 
to the Deferred Compensation Plan. As of December 31, 2023, there were 230,295 phantom stock units outstanding pursuant to 
our Non-Employee Director's Deferral Program.

Employee Stock Purchase Plan

16. Fair Value Measurements

In 2007, the Company's Board of Directors adopted the 2008 Employee Stock Purchase Plan, or ESPP, to provide equity-
based  incentives  to  eligible  employees.  The  ESPP  is  intended  to  qualify  as  an  "employee  stock  purchase  plan"  under 
Section 423 of the Code, and has been adopted by the board to enable our eligible employees to purchase the Company's shares 
of  common  stock  through  payroll  deductions.  The  ESPP  became  effective  on  January  1,  2008  with  a  maximum  of  500,000 
shares  of  the  common  stock  available  for  issuance,  subject  to  adjustment  upon  a  merger,  reorganization,  stock  split  or  other 
similar corporate change. The Company filed a registration statement on Form S-8 with the SEC with respect to the ESPP. The 
common stock is offered for purchase through a series of successive offering periods. Each offering period will be three months 
in duration and will begin on the first day of each calendar quarter, with the first offering period having commenced on January 
1, 2008. The ESPP provides for eligible employees to purchase the common stock at a purchase price equal to 85% of the lesser 
of (1) the market value of the common stock on the first day of the offering period or (2) the market value of the common stock 
on the last day of the offering period. The ESPP was approved by our stockholders at our 2008 annual meeting of stockholders. 
As of December 31, 2023, 224,159 shares of our common stock had been issued under the ESPP.

We  are  required  to  disclose  fair  value  information  with  regard  to  certain  of  our  financial  instruments,  whether  or  not 

recognized in the consolidated balance sheets, for which it is practical to estimate fair value. The FASB guidance defines fair 

value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 

participants  on  the  measurement  date.  We  measure  and/or  disclose  the  estimated  fair  value  of  certain  financial  assets  and 

liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from 

sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. 

This  hierarchy  consists  of  three  broad  levels:  Level  1  -  quoted  prices  (unadjusted)  in  active  markets  for  identical  assets  or 

liabilities that the reporting entity can access at the measurement date; Level 2 - inputs other than quoted prices included within 

Level 1, that are observable for the asset or liability, either directly or indirectly; and Level 3 - unobservable inputs for the asset 

or  liability  that  are  used  when  little  or  no  market  data  is  available.  We  follow  this  hierarchy  for  our  assets  and  liabilities 

measured  at  fair  value  on  a  recurring  and  nonrecurring  basis.  In  instances  in  which  the  determination  of  the  fair  value 

measurement  is  based  on  inputs  from  different  levels  of  the  fair  value  hierarchy,  the  level  in  the  fair  value  hierarchy  within 

which  the  entire  fair  value  measurement  falls  is  based  on  the  lowest  level  of  input  that  is  significant  to  the  fair  value 

measurement  in  its  entirety.  Our  assessment  of  the  significance  of  the  particular  input  to  the  fair  value  measurement  in  its

We  evaluate  real  estate  investments  and  debt  and  preferred  equity  investments,  including  intangibles,  for  potential 

impairment  primarily  utilizing  cash  flow  projections  that  apply,  among  other  things,  estimated  revenue  and  expense  growth 

rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and 

sales contracts. All of which are classified as Level 3 inputs.

In June 2023, the Company sold a 49.9% interest in its 245 Park Avenue investment, which resulted in the Company no 

longer  retaining  a  controlling  interest  in  the  entity,  as  defined  in  ASC  810,  and  deconsolidation  of  the  50.1%  interest  we 

retained.  We  recorded  our  investment  at  fair  value  which  resulted  in  the  recognition  of  a  fair  value  adjustment  of 

($17.0 million) during the year ended December 31, 2023. The fair value of our investment was determined by the terms of the 

joint venture agreement. 

In September 2022, the Company recorded at fair value the assets acquired and liabilities assumed at 245 Park Avenue. 

This fair value was determined using a third-party valuation which primarily utilized cash flow projections that apply, among 

other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison 

approach, which utilizes comparable sales, listings and sales contracts, all of which are classified as Level 3 inputs.

Marketable securities classified as Level 1 are derived from quoted prices in active markets. The valuation technique used 
to measure the fair value of marketable securities classified as Level 2 were valued based on quoted market prices or model 
driven valuations using the significant inputs derived from or corroborated by observable market data. We do not intend to sell 
these  securities  and  it  is  not  more  likely  than  not  that  we  will  be  required  to  sell  the  investments  before  recovery  of  their 
amortized cost bases.

The fair value of derivative instruments is based on current market data received from financial sources that trade such 
instruments and are based on prevailing market data and derived from third party proprietary models based on well-recognized 
financial principles and reasonable estimates about relevant future market conditions, which are classified as Level 2 inputs.

The financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash and 
cash  equivalents,  restricted  cash,  accounts  receivable,  accounts  payable  and  accrued  expenses,  debt  and  preferred  equity 
investments, mortgages and other loans payable and other secured and unsecured debt. The carrying amount of cash and cash 
equivalents,  restricted  cash,  accounts  receivable,  and  accounts  payable  and  accrued  expenses  reported  in  our  consolidated 
balance sheets approximates fair value due to the short-term nature of these instruments. The fair value of debt and preferred 
equity investments, which is classified as Level 3, is estimated by discounting the future cash flows using current interest rates 
at  which  similar  loans  with  the  same  maturities  would  be  made  to  borrowers  with  similar  credit  ratings.  The  fair  value  of 
borrowings, which is classified as Level 3, is estimated by discounting the contractual cash flows of each debt instrument to 
their present value using adjusted market interest rates, which is provided by a third-party specialist.

The following table provides the carrying value and fair value of these financial instruments as of December 31, 2023 and

debt and preferred equity investments had an estimated fair value ranging between $0.6 billion and $0.6 billion.
As  of  December  31,  2023,  variable  rate  debt  with  a  carrying  value  of  $110.0  million  and  fair  value  of  $108.6  million  is  included  in  the  Company's 
alternative strategy portfolio. 

Disclosures  regarding  fair  value  of  financial  instruments  was  based  on  pertinent  information  available  to  us  as  of 
December  31,  2023  and  2022.  Such  amounts  have  not  been  comprehensively  revalued  for  purposes  of  these  financial 
statements since that date and current estimates of fair value may differ significantly from the amounts presented herein.

17. Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, including, but not limited to, 
interest  rate  swaps,  caps,  collars  and  floors,  to  manage,  or  hedge  interest  rate  risk.  We  hedge  our  exposure  to  variability  in 
future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize 
all derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a 
derivative  is  a  hedge,  depending  on  the  nature  of  the  hedge,  changes  in  the  fair  value  of  the  derivative  will  either  be  offset 
against  the  change  in  fair  value  of  the  hedge  asset,  liability,  or  firm  commitment  through  earnings,  or  recognized  in  other 
comprehensive income (loss) until the hedged item is recognized in earnings. Reported net income and equity may increase or 
decrease  prospectively,  depending  on  future  levels  of  interest  rates  and  other  variables  affecting  the  fair  values  of  derivative 
instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are 
effective hedging instruments.

The  following  table  summarizes  the  notional  value  at  inception  and  fair  value  of  our  consolidated  derivative  financial 
instruments as of December 31, 2023 based  on Level 2  information. The  notional  value is an indication of the extent of our 
involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (dollars in 
thousands).

During the year ended December 31, 2023, we recorded a loss of $10.4 million based on the changes in the fair value of 

an interest rate cap we sold and a forward-starting interest rate swap, which is included in Purchase price and other fair value 

adjustments  in  the  consolidated  statements  of  operations.  During  the  year  ended  December  31,  2022,  we  recorded  a  loss  of 

$1.7 million based on the changes in the fair value of an interest rate cap we sold. No interest rate caps were sold or forward-

starting interest rate swaps entered into during the year ended December 31, 2021. During the years ended December 31, 2023, 

2022,  and  2021,  we  recorded  losses  of  $0.2  million,  $0.3  million,  and  $0.0  million,  respectively,  on  the  changes  in  the  fair 

value, which is included in interest expense in the consolidated statements of operations.   

Certain agreements the Company has with each of its derivative counterparties contain a provision where if the Company 

defaults  on  any  of  its  indebtedness,  then  the  Company  could  also  be  declared  in  default  on  its  derivative  obligations.  As  of 

December  31,  2023,  the  fair  value  of  derivatives  in  a  net  liability  position,  including  accrued  interest  but  excluding  any 

adjustment  for  nonperformance  risk  related  to  these  agreements  was  $17.5  million.  As  of  December  31,  2023,  the  Company 

was not required to post any collateral related to these agreements and was not in breach of any agreement provisions. If the 

Company  had  breached  any  of  these  provisions,  it  could  have  been  required  to  settle  its  obligations  under  the  agreements  at 

their aggregate termination value of $18.3 million as of December 31, 2023.

Gains and losses on terminated hedges are included in accumulated other comprehensive income, and are recognized into 

earnings over the term of the related obligation. Over time, the realized and unrealized gains and losses held in accumulated 

other comprehensive income will be reclassified into earnings as an adjustment to interest expense in the same periods in which 

the hedged interest payments affect earnings. We estimate that ($32.5 million) of the current balance held in accumulated other 

comprehensive income will be reclassified into interest expense and ($7.6 million) of the portion related to our share of joint 

venture accumulated other comprehensive income (loss) will be reclassified into equity in net loss from unconsolidated joint 

ventures within the next 12 months.

The following table presents our derivative financial instruments and our share of our joint ventures' derivative financial 

instruments that are designated and qualify as hedging instruments on the consolidated statements of operations for the years 

ended December 31, 2023, 2022, and 2021, respectively (in thousands):

Marketable securities classified as Level 1 are derived from quoted prices in active markets. The valuation technique used 

to measure the fair value of marketable securities classified as Level 2 were valued based on quoted market prices or model 

driven valuations using the significant inputs derived from or corroborated by observable market data. We do not intend to sell 

these  securities  and  it  is  not  more  likely  than  not  that  we  will  be  required  to  sell  the  investments  before  recovery  of  their 

amortized cost bases.

The fair value of derivative instruments is based on current market data received from financial sources that trade such 

instruments and are based on prevailing market data and derived from third party proprietary models based on well-recognized 

financial principles and reasonable estimates about relevant future market conditions, which are classified as Level 2 inputs.

The financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash and 

cash  equivalents,  restricted  cash,  accounts  receivable,  accounts  payable  and  accrued  expenses,  debt  and  preferred  equity 

investments, mortgages and other loans payable and other secured and unsecured debt. The carrying amount of cash and cash 

equivalents,  restricted  cash,  accounts  receivable,  and  accounts  payable  and  accrued  expenses  reported  in  our  consolidated 

balance sheets approximates fair value due to the short-term nature of these instruments. The fair value of debt and preferred 

equity investments, which is classified as Level 3, is estimated by discounting the future cash flows using current interest rates 

at  which  similar  loans  with  the  same  maturities  would  be  made  to  borrowers  with  similar  credit  ratings.  The  fair  value  of 

borrowings, which is classified as Level 3, is estimated by discounting the contractual cash flows of each debt instrument to 

their present value using adjusted market interest rates, which is provided by a third-party specialist.

The following table provides the carrying value and fair value of these financial instruments as of December 31, 2023 and

Amounts exclude net deferred financing costs.

As of December 31, 2023, debt and preferred equity investments had an estimated fair value of approximately $0.3 billion. As of December 31, 2022, 

debt and preferred equity investments had an estimated fair value ranging between $0.6 billion and $0.6 billion.

As  of  December  31,  2023,  variable  rate  debt  with  a  carrying  value  of  $110.0  million  and  fair  value  of  $108.6  million  is  included  in  the  Company's 

alternative strategy portfolio. 

Disclosures  regarding  fair  value  of  financial  instruments  was  based  on  pertinent  information  available  to  us  as  of 

December  31,  2023  and  2022.  Such  amounts  have  not  been  comprehensively  revalued  for  purposes  of  these  financial 

statements since that date and current estimates of fair value may differ significantly from the amounts presented herein.

17. Financial Instruments: Derivatives and Hedging

interest  rate  swaps,  caps,  collars  and  floors,  to  manage,  or  hedge  interest  rate  risk.  We  hedge  our  exposure  to  variability  in 

future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize 

all derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a 

derivative  is  a  hedge,  depending  on  the  nature  of  the  hedge,  changes  in  the  fair  value  of  the  derivative  will  either  be  offset 

against  the  change  in  fair  value  of  the  hedge  asset,  liability,  or  firm  commitment  through  earnings,  or  recognized  in  other 

comprehensive income (loss) until the hedged item is recognized in earnings. Reported net income and equity may increase or 

decrease  prospectively,  depending  on  future  levels  of  interest  rates  and  other  variables  affecting  the  fair  values  of  derivative 

instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are 

effective hedging instruments.

The  following  table  summarizes  the  notional  value  at  inception  and  fair  value  of  our  consolidated  derivative  financial 

instruments as of December 31, 2023 based  on Level 2 information. The  notional  value is an indication of the extent of our 

involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (dollars in

During the year ended December 31, 2023, we recorded a loss of $10.4 million based on the changes in the fair value of 
an interest rate cap we sold and a forward-starting interest rate swap, which is included in Purchase price and other fair value 
adjustments  in  the  consolidated  statements  of  operations.  During  the  year  ended  December  31,  2022,  we  recorded  a  loss  of 
$1.7 million based on the changes in the fair value of an interest rate cap we sold. No interest rate caps were sold or forward-
starting interest rate swaps entered into during the year ended December 31, 2021. During the years ended December 31, 2023, 
2022,  and  2021,  we  recorded  losses  of  $0.2  million,  $0.3  million,  and  $0.0  million,  respectively,  on  the  changes  in  the  fair 
value, which is included in interest expense in the consolidated statements of operations.   

Certain agreements the Company has with each of its derivative counterparties contain a provision where if the Company 
defaults  on  any  of  its  indebtedness,  then  the  Company  could  also  be  declared  in  default  on  its  derivative  obligations.  As  of 
December  31,  2023,  the  fair  value  of  derivatives  in  a  net  liability  position,  including  accrued  interest  but  excluding  any 
adjustment  for  nonperformance  risk  related  to  these  agreements  was  $17.5  million.  As  of  December  31,  2023,  the  Company 
was not required to post any collateral related to these agreements and was not in breach of any agreement provisions. If the 
Company  had  breached  any  of  these  provisions,  it  could  have  been  required  to  settle  its  obligations  under  the  agreements  at 
their aggregate termination value of $18.3 million as of December 31, 2023.

Gains and losses on terminated hedges are included in accumulated other comprehensive income, and are recognized into 
earnings over the term of the related obligation. Over time, the realized and unrealized gains and losses held in accumulated 
other comprehensive income will be reclassified into earnings as an adjustment to interest expense in the same periods in which 
the hedged interest payments affect earnings. We estimate that ($32.5 million) of the current balance held in accumulated other 
comprehensive income will be reclassified into interest expense and ($7.6 million) of the portion related to our share of joint 
venture accumulated other comprehensive income (loss) will be reclassified into equity in net loss from unconsolidated joint 
ventures within the next 12 months.

The following table presents our derivative financial instruments and our share of our joint ventures' derivative financial 
instruments that are designated and qualify as hedging instruments on the consolidated statements of operations for the years

The Operating Partnership is the lessor and the sublessor to tenants under operating and sales-type leases. The minimum 

rental amounts due under the leases are generally subject to scheduled fixed increases or adjustments. The leases generally also 

require that the tenants reimburse us for increases in certain operating costs and real estate taxes above their base year costs.

December 31, 2023

The  building  employees  are  covered  by  multi-employer  defined  benefit  pension  plans  and  post-retirement  health  and 
welfare  plans.  We  participate  in  the  Building  Service  32BJ,  or  Union,  Pension  Plan  and  Health  Plan.  The  Pension  Plan  is  a 
multi-employer,  non-contributory  defined  benefit  pension  plan  that  was  established  under  the  terms  of  collective  bargaining 
agreements  between  the  Service  Employees  International  Union,  Local  32BJ,  the  Realty  Advisory  Board  on  Labor 
Relations, Inc. and certain other employees. This Pension Plan is administered by a joint board of trustees consisting of union 
trustees  and  employer  trustees  and  operates  under  employer  identification  number  13-1879376.  The  Pension  Plan  year  runs 
from July 1 to June 30. Employers contribute to the Pension Plan at a fixed rate on behalf of each covered employee. Separate 
actuarial  information  regarding  such  pension  plans  is  not  made  available  to  the  contributing  employers  by  the  union 
administrators or trustees, since the plans do not maintain separate records for each reporting unit. However, on September 28, 
2021, September 28, 2022 and September 28, 2023, the actuary certified that for the plan years beginning July 1, 2021, July 1, 
2022  and  July  1,  2023,  the  Pension  Plan  was  in  critical  or  endangered  status  under  the  Pension  Protection  Act  of  2006.  The 
Pension  Plan  trustees  adopted  a  rehabilitation  plan  consistent  with  this  requirement.  No  surcharges  have  been  paid  to  the 
Pension  Plan  as  of  December  31,  2023.  For  the  Pension  Plan  years  ended  June  30,  2023,  2022  and  2021,  the  plan  received 
contributions from employers totaling $317.9 million, $305.7 million and $290.1 million, respectively. Our contributions to the 
Pension Plan represent less than 5.0% of total contributions to the plan.

The  Health  Plan  was  established  under  the  terms  of  collective  bargaining  agreements  between  the  Union,  the  Realty 
Advisory Board on Labor Relations, Inc. and certain other employers. The Health Plan provides health and other benefits to 
eligible participants employed in the building service industry who are covered under collective bargaining agreements, or other 
written agreements, with the Union. The Health Plan is administered by a Board of Trustees with equal representation by the 
employers  and  the  Union  and  operates  under  employer  identification  number  13-2928869.  The  Health  Plan  receives 
contributions  in  accordance  with  collective  bargaining  agreements  or  participation  agreements.  Generally,  these  agreements 
provide that the employers contribute to the Health Plan at a fixed rate on behalf of each covered employee. For the Health Plan 
years ended, June 30, 2023, 2022 and 2021, the plan received contributions from employers totaling $1.9 billion, $1.6 billion 
and $1.5 billion, respectively. Our contributions to the Health Plan represent less than 5.0% of total contributions to the plan.

Contributions we made to the multi-employer plans for the years ended December 31, 2023, 2022 and 2021 are included

In August 1997, we implemented a 401(K) Savings/Retirement Plan, or the 401(K) Plan, to cover eligible employees of 
ours, and any designated affiliate. The 401(K) Plan permits eligible employees to defer up to 15% of their annual compensation, 
subject  to  certain  limitations  imposed  by  the  Code.  The  employees'  elective  deferrals  are  immediately  vested  and  non-
forfeitable  upon  contribution  to  the  401(K)  Plan.  During  2003,  we  amended  our  401(K)  Plan  to  provide  for  discretionary 
matching  contributions  only.  For  2023,  2022  and  2021,  a  matching  contribution  equal  to  100%  of  the  first  4%  of  annual 
compensation  was  made.  For  the  years  ended  December  31,  2023,  2022  and  2021,  we  made  matching  contributions  of  $1.8 
million, $1.5 million, and $1.5 million, respectively.

Insurance

As of December 31, 2023, the Company and the Operating Partnership were not involved in any material litigation nor, to 

management's  knowledge,  was  any  material  litigation  threatened  against  us  or  our  portfolio  which  if  adversely  determined 

Our management believes that the properties are in compliance in all material respects with applicable Federal, state and 

local ordinances and regulations regarding environmental issues. Management is not aware of any environmental liability that it 

believes would have a materially adverse impact on our financial position, results of operations or cash flows. Management is 

unaware of any instances in which it would incur significant environmental cost if any of our properties were sold.

We have entered into employment agreements with certain executives, which expire between January 2025 and January 

2026. The minimum cash-based compensation associated with these employment agreements, which is comprised only of base 

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake 

and  terrorism,  excluding  nuclear,  biological,  chemical,  and  radiological  terrorism  ("NBCR"),  within  two  property  insurance 

programs and liability insurance. Separate property and liability coverage may be purchased on a stand-alone basis for certain 

assets, such as development projects. Additionally, one of our captive insurance companies, Belmont Insurance Company, or 

Belmont,  provides  coverage  for  NBCR  terrorist  acts  above  a  specified  trigger.  Belmont's  retention  is  reinsured  by  our  other 

captive insurance company, Ticonderoga Insurance Company ("Ticonderoga"). If Belmont or Ticonderoga are required to pay a 

claim under our insurance policies, we would ultimately record the loss to the extent of required payments. However, there is 

no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are 

uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated 

future  cash  flows  from  those  properties.  Additionally,  our  debt  instruments  contain  customary  covenants  requiring  us  to 

maintain insurance and we could default under our debt instruments if the cost and/or availability of certain types of insurance 

make  it  impractical  or  impossible  to  comply  with  such  covenants  relating  to  insurance.  Belmont  and  Ticonderoga  provide 

coverage solely on properties owned by the Company or its affiliates.

Furthermore, with respect to certain of our properties, including properties held by joint ventures or subject to triple net 

leases, insurance coverage is obtained by a third-party and we do not control the coverage. While we may have agreements with 

such  third  parties  to  maintain  adequate  coverage  and  we  monitor  these  policies,  such  coverage  ultimately  may  not  be 

maintained or adequately cover our risk of loss.

Belmont had loss reserves of $3.3 million and $3.1 million as of December 31, 2023 and 2022, respectively. Ticonderoga 

had no loss reserves as of December 31, 2023 and 2022.

Lease Arrangements

We are a tenant under leases for certain properties, including ground leases. These leases have expirations from 2033 to 

2119,  or  2043  to  2119  as  fully  extended.  Certain  leases  offer  extension  options  which  we  assess  against  relevant  economic 

factors to determine whether we are reasonably certain of exercising or not exercising the option. Lease payments associated 

with  renewal  periods  that  we  are  reasonably  certain  will  be  exercised,  if  any,  are  included  in  the  measurement  of  the 

corresponding lease liability and right of use asset.

Certain  of  our  leases  are  subject  to  rent  resets,  generally  based  on  a  percentage  of  the  then  fair  market  value,  a  fixed 

amount, or a percentage of the preceding rent at specified future dates. Rent resets will be recognized in the periods in which 

they are incurred. Additionally, certain of our leases are subject to percentage rent arrangements based on thresholds established 

in the lease agreement, such as percentage of sales at the property. Percentage rents will be recognized in the periods in which 

they are incurred.

The table below summarizes our current lease arrangements as of  December 31, 2023:

21. Segment Information

The  Company  has  three  reportable  segments,  real  estate,  debt  and  preferred  equity  investments,  and  SUMMIT.  In  the 
fourth quarter of 2023, due to quantitative thresholds, SUMMIT was identified as a reportable segment. As such, prior period 
segment data has been restated to reflect SUMMIT as a reportable segment for comparative purposes. 

We  evaluate  real  estate  performance  and  allocate  resources  based  on  earnings  contributions.  The  primary  sources  of 
revenue  are  generated  from  tenant  rents,  escalations  and  reimbursement  revenue.  Real  estate  property  operating  expenses 
consist  primarily  of  security,  maintenance,  utility  costs,  insurance,  real  estate  taxes  and,  at  certain  properties,  ground  rent 
expense.  See  Note  5,  "Debt  and  Preferred  Equity  Investments,"  for  additional  details  on  our  debt  and  preferred  equity 
investments.  SUMMIT  currently  operates  one  location  at  One  Vanderbilt  Avenue  in  midtown  Manhattan  with  the  primary 
source of revenue generated from ticket sales.

Selected consolidated results of operations for the years ended December 31, 2023, 2022, and 2021, and selected asset 

information as of December 31, 2023 and 2022, regarding our operating segments are as follows (in thousands):

We allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. 
We  do  not  allocate  marketing,  general  and  administrative  expenses  to  the  debt  and  preferred  equity  segment  because  that 
segment does not have dedicated personnel and the use of personnel and resources is dependent on transaction volume between 
the  three  segments,  which  varies  between  periods.  In  addition,  we  base  performance  on  the  individual  segments  prior  to 
allocating  marketing,  general  and  administrative  expenses.  SUMMIT  segment  incurs  its  own  marketing,  general  and 
administrative  expenses  for  its  dedicated  personnel,  which  are  included  in  SUMMIT  Operator  expenses  in  the  consolidated 
statements  of  operations.  For  the  years  ended,  December  31,  2023,  2022,  and  2021  marketing,  general  and  administrative 
expenses  totaled  $111.4  million,  $93.8  million,  and  $94.9  million  respectively.  All  other  expenses,  except  interest  and 
SUMMIT operator expenses, relate entirely to the real estate assets.

There  were  no  transactions  between  the  above  three  segments  other  than  the  SUMMIT  lease  with  our  One  Vanderbilt 

Avenue joint venture, which is part of the real estate segment. See Note 10, "Related Party Transactions."

21. Segment Information

The  Company  has  three  reportable  segments,  real  estate,  debt  and  preferred  equity  investments,  and  SUMMIT.  In  the 

fourth quarter of 2023, due to quantitative thresholds, SUMMIT was identified as a reportable segment. As such, prior period 

segment data has been restated to reflect SUMMIT as a reportable segment for comparative purposes. 

We  evaluate  real  estate  performance  and  allocate  resources  based  on  earnings  contributions.  The  primary  sources  of 

revenue  are  generated  from  tenant  rents,  escalations  and  reimbursement  revenue.  Real  estate  property  operating  expenses 

consist  primarily  of  security,  maintenance,  utility  costs,  insurance,  real  estate  taxes  and,  at  certain  properties,  ground  rent 

expense.  See  Note  5,  "Debt  and  Preferred  Equity  Investments,"  for  additional  details  on  our  debt  and  preferred  equity 

investments.  SUMMIT  currently  operates  one  location  at  One  Vanderbilt  Avenue  in  midtown  Manhattan  with  the  primary 

source of revenue generated from ticket sales.

Selected consolidated results of operations for the years ended December 31, 2023, 2022, and 2021, and selected asset 

information as of December 31, 2023 and 2022, regarding our operating segments are as follows (in thousands):

We allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. 

We  do  not  allocate  marketing,  general  and  administrative  expenses  to  the  debt  and  preferred  equity  segment  because  that 

segment does not have dedicated personnel and the use of personnel and resources is dependent on transaction volume between 

the  three  segments,  which  varies  between  periods.  In  addition,  we  base  performance  on  the  individual  segments  prior  to 

allocating  marketing,  general  and  administrative  expenses.  SUMMIT  segment  incurs  its  own  marketing,  general  and 

administrative  expenses  for  its  dedicated  personnel,  which  are  included  in  SUMMIT  Operator  expenses  in  the  consolidated 

statements  of  operations.  For  the  years  ended,  December  31,  2023,  2022,  and  2021  marketing,  general  and  administrative 

expenses  totaled  $111.4  million,  $93.8  million,  and  $94.9  million  respectively.  All  other  expenses,  except  interest  and 

SUMMIT operator expenses, relate entirely to the real estate assets.

There  were  no  transactions  between  the  above  three  segments  other  than  the  SUMMIT  lease  with  our  One  Vanderbilt 

Avenue joint venture, which is part of the real estate segment. See Note 10, "Related Party Transactions."

2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 

the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 

required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 

rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 

audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 

error  or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial 

statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included 

examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 

evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 

presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 

were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that 

are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex  judgments.  The 

communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken 

as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit 

matters or on the accounts or disclosures to which they relate.

Joint Venture Consolidation Assessment

Description of 
the Matter

The  Company  accounted  for  certain  investments  in  real  estate  joint  ventures  under  the  equity  method  of 

accounting and consolidated certain other investments in real estate joint ventures. At December 31, 2023, 

the Company’s investments in unconsolidated joint ventures was $3.0 billion and noncontrolling interests in 

consolidated  other  partnerships  was  $69.6  million.  As  discussed  in  Note  2  to  the  consolidated  financial 

statements, for each joint venture, the Company evaluated the rights provided to each party in the venture to 

assess the consolidation of the venture.

The aggregate cost of land, buildings and improvements, before depreciation, for Federal income tax purposes as of

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error  or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial 
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

How We 
Addressed the 
Matter in Our 
Audit

Auditing management’s joint venture consolidation analyses was complex and highly judgmental due to the 
subjectivity in assessing which activities most significantly impact a joint venture’s economic performance 
based on the purpose and design of the entity over the duration of its expected life and assessing which party 
has rights to direct those activities. We tested the Company’s controls over the assessment of joint venture 
consolidation. For example, we tested controls over management's review of the consolidation analyses for 
newly formed ventures as well as controls over management's identification of reconsideration events which 
could trigger modified consolidation conclusions for existing ventures.

To  test  the  Company’s  consolidation  assessment  for  real  estate  joint  ventures,  our  procedures  included, 
among others, reviewing new and amended joint venture agreements and discussing with management the 
nature of the rights conveyed to the Company through the joint venture agreements as well as the business 
purpose  of  the  joint  venture  transactions.  We  reviewed  management’s  assessment  of  the  activities  that 
would most significantly impact the joint venture’s economic performance and evaluated whether the joint 
venture  agreements  provided  participating  or  protective  rights  to  the  Company.  We  also  evaluated 
transactions  with  the  joint  ventures  for  events  which  would  require  a  reconsideration  of  previous 
consolidation conclusions.

Description of 
the Matter

Impairment of Commercial Real Estate Properties and Investments in Unconsolidated Joint Ventures
At December 31, 2023, the Company’s commercial real estate properties, at cost totaled approximately $5.0 
billion.  As  described  in  Note  2  to  the  consolidated  financial  statements,  real  estate  properties  are 
periodically reviewed for impairment when circumstances indicate that the carrying value of a property may 
not  be  recoverable.  For  the  year  ended  December  31,  2023,  the  Company  recognized  $249.5  million  of 
impairment  losses  on  its  commercial  real  estate  properties,  which  is  included  in  depreciable  real  estate 
reserves and impairments in the consolidated statements of operations. 

How We 
Addressed the 
Matter in Our 
Audit

At  December  31,  2023,  the  Company’s  investments  in  unconsolidated  joint  ventures  was  $3.0  billion.  As 
described  in  Note  2  to  the  consolidated  financial  statements,  investments  in  unconsolidated  joint  ventures 
are  assessed  for  recoverability,  and  if  it  is  determined  that  a  loss  in  value  of  the  investment  is  other  than 
temporary,  the  investment  is  written  down  to  its  fair  value.  For  the  year  ended  December  31,  2023,  the 
Company  recognized  $132.9  million  of  other  than  temporary  impairment  losses  on  its  investments  in 
unconsolidated joint ventures, which is included in depreciable real estate reserves and impairments in the 
consolidated statements of operations.

Auditing the Company’s accounting for impairment of commercial real estate properties and investments in 
unconsolidated  joint  ventures  was  especially  challenging  and  involved  a  high  degree  of  subjectivity  as  a 
result of the assumptions and estimates inherent in the determination of estimated future cash flows and the 
estimated fair value of commercial real estate properties and investments in unconsolidated joint ventures. 
In  particular,  management’s  assumptions  and  estimates  included  estimated  revenue  and  expense  growth 
rates, discount rates and capitalization rates, which were sensitive to expectations about future operations, 
market  or  economic  conditions,  demand  and  competition.  We  obtained  an  understanding,  evaluated  the 
design,  and  tested  the  operating  effectiveness  of  controls  over  the  Company’s  commercial  real  estate 
properties  and  investments  in  unconsolidated  joint  ventures  impairment  process.  This  included  testing  of 
controls over management's review of the significant assumptions and data inputs utilized in the estimation 
of expected future cash flows and the determination of fair value.

To test the Company's accounting for impairment of commercial real estate properties and investments in 
unconsolidated  joint  ventures,  we  performed  audit  procedures  that  included,  among  others,  evaluating  the 
methodologies applied and testing the significant assumptions discussed above and the underlying data used 
by the Company in its impairment analyses. We held discussions with management about the current status 
of  potential  transactions  and  the  Company’s  intent  and  ability  to  fund  future  operations  of  investments  in 
unconsolidated joint ventures.  We also discussed management’s judgments to understand the probability of 
future  events  that  could  affect  the  holding  period  and  other  cash  flow  assumptions  for  the  properties.  In 
certain cases, we involved our valuation specialists to assist in performing these procedures. We compared 
the significant assumptions used by management to historical data and observable market-specific data. We 
also  assessed  management’s  estimates  and  performed  sensitivity  analyses  of  significant  assumptions  to 
evaluate the changes in estimated future cash flows that would result from changes in the assumptions. In 
addition, we assessed information and events subsequent to the balance sheet date to corroborate certain of 
the key assumptions utilized by management.

Report of Independent Registered Public Accounting Firm

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of SL Green Realty Corp.

Opinion on Internal Control Over Financial Reporting

To the Partners of SL Green Operating Partnership, L.P.

Opinion on the Financial Statements

We have audited SL Green Realty Corp.'s internal control over financial reporting as of December 31, 2023, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, SL Green Realty Corp. (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB),  the  2023  consolidated  financial  statements  of  the  Company  and  our  report  dated  February  23,  2024  expressed  an 
unqualified opinion thereon.

Basis for Opinion

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on  Internal  Control  over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  internal  control 
over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all 
material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a 
reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted  accounting  principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures 
that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and 
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or 
disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

How We 
Addressed the 
Matter in Our 
Audit

Auditing management’s joint venture consolidation analyses was complex and highly judgmental due to the 
subjectivity in assessing which activities most significantly impact a joint venture’s economic performance 
based on the purpose and design of the entity over the duration of its expected life and assessing which party 
has rights to direct those activities. We tested the Operating Partnership’s controls over the assessment of 
joint venture consolidation. For example, we tested controls over management's review of the consolidation 
analyses for newly formed ventures as well as controls over management's identification of reconsideration 
events which could trigger modified consolidation conclusions for existing ventures.

To  test  the  Operating  Partnership’s  consolidation  assessment  for  real  estate  joint  ventures,  our  procedures 
included,  among  others,  reviewing  new  and  amended  joint  venture  agreements  and  discussing  with 
management  the  nature  of  the  rights  conveyed  to  the  Operating  Partnership  through  the  joint  venture 
agreements  as  well  as  the  business  purpose  of  the  joint  venture  transactions.  We  reviewed  management’s 
assessment of the activities that would most significantly impact the joint venture’s economic performance 
and  evaluated  whether  the  joint  venture  agreements  provided  participating  or  protective  rights  to  the 
Operating  Partnership.  We  also  evaluated  transactions  with  the  joint  ventures  for  events  which  would 
require a reconsideration of previous consolidation conclusions.

                              Impairment of Commercial Real Estate Properties and Investments in Unconsolidated Joint Ventures

Description of 
the Matter

At  December  31,  2023,  the  Operating  Partnership’s  commercial  real  estate  properties,  at  cost  totaled 
approximately  $5.0  billion.  As  described  in  Note  2  to  the  consolidated  financial  statements,  real  estate 
properties are periodically reviewed for impairment when circumstances indicate that the carrying value of a 
property  may  not  be  recoverable.  For  the  year  ended  December  31,  2023,  the  Operating  Partnership 
recognized $249.5 million of impairment losses on its commercial real estate properties, which is included 
in depreciable real estate reserves and impairments in the consolidated statements of operations. 

How We 
Addressed the 
Matter in Our 
Audit

At December 31, 2023, the Operating Partnership’s investments in unconsolidated joint ventures was $3.0 
billion. As described in Note 2 to the consolidated financial statements, investments in unconsolidated joint 
ventures are assessed for recoverability, and if it is determined that a loss in value of the investment is other 
than temporary, the investment is written down to its fair value. For the year ended December 31, 2023, the 
Operating  Partnership  recognized  $132.9  million  of  other  than  temporary  impairment  losses  on  its 
investments  in  unconsolidated  joint  ventures,  which  is  included  in  depreciable  real  estate  reserves  and 
impairments in the consolidated statements of operations.

Auditing  the  Operating  Partnership’s  accounting  for  impairment  of  commercial  real  estate  properties  and 
investments  in  unconsolidated  joint  ventures  was  especially  challenging  and  involved  a  high  degree  of 
subjectivity  as  a  result  of  the  assumptions  and  estimates  inherent  in  the  determination  of  estimated  future 
cash  flows  and  the  estimated  fair  value  of  commercial  real  estate  properties  and  investments  in 
unconsolidated  joint  ventures.  In  particular,  management’s  assumptions  and  estimates  included  estimated 
revenue  and  expense  growth  rates,  discount  rates  and  capitalization  rates,  which  were  sensitive  to 
expectations about future operations, market or economic conditions, demand and competition. We obtained 
an understanding, evaluated the design, and tested the operating effectiveness of controls over the Operating 
Partnership’s commercial real estate properties and investments in unconsolidated joint ventures impairment 
process. This included testing of controls over management's review of the significant assumptions and data 
inputs utilized in the estimation of expected future cash flows and the determination of fair value.

To  test  the  Operating  Partnership's  accounting  for  impairment  of  commercial  real  estate  properties  and 
investments in unconsolidated joint ventures, we performed audit procedures that included, among others, 
evaluating  the  methodologies  applied  and  testing  the  significant  assumptions  discussed  above  and  the 
underlying  data  used  by  the  Operating  Partnership  in  its  impairment  analyses.  We  held  discussions  with 
management  about  the  current  status  of  potential  transactions  and  the  Operating  Partnership’s  intent  and 
ability  to  fund  future  operations  of  investments  in  unconsolidated  joint  ventures.    We  also  discussed 
management’s judgments to understand the probability of future events that could affect the holding period 
and other cash flow assumptions for the properties. In certain cases, we involved our valuation specialists to 
assist  in  performing  these  procedures.  We  compared  the  significant  assumptions  used  by  management  to 
historical  data  and  observable  market-specific  data.  We  also  assessed  management’s  estimates  and 
performed sensitivity analyses  of significant assumptions to evaluate  the changes in estimated future cash 
flows that would result from changes in the assumptions. In addition, we assessed information and events 
subsequent to the balance sheet date to corroborate certain of the key assumptions utilized by management.

Report of Independent Registered Public Accounting Firm

To the Partners of SL Green Operating Partnership, L.P.

Opinion on Internal Control Over Financial Reporting

We  have  audited  SL  Green  Operating  Partnership,  L.P.'s  internal  control  over  financial  reporting  as  of  December  31,  2023, 
based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, SL Green Operating Partnership, L.P. (the 
Operating  Partnership)  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of 
December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB),  the  2023  consolidated  financial  statements  of  the  Operating  Partnership  and  our  report  dated  February  23,  2024 
expressed an unqualified opinion thereon.

Basis for Opinion

The Operating Partnership’s management is responsible for maintaining effective internal control over financial reporting and 
for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's 
Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Operating Partnership's 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Operating Partnership in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all 
material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a 
reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

financial reporting was effective as of December 31, 2023.

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted  accounting  principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures 
that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and 
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or 
disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The  Company  maintains  disclosure  controls  and  procedures  that  are  designed  to  ensure  that  information  required  to  be 

disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the 

SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including 

the  Company's  Chief  Executive  Officer  and  Chief  Financial  Officer,  as  appropriate,  to  allow  timely  decisions  regarding 

required disclosure based closely on the definition of "disclosure controls and procedures" in Rule 13a-15(e) of the Exchange 

Act. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, 

not  absolute,  assurance  that  it  will  detect  or  uncover  failures  within  the  Company  to  disclose  material  information  otherwise 

required to be set forth in our periodic reports. Also, the Company has investments in certain unconsolidated entities. As the 

Company  does  not  control  these  entities,  its  disclosure  controls  and  procedures  with  respect  to  such  entities  are  necessarily 

substantially more limited than those the Company maintains with respect to its consolidated subsidiaries.

As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with 

the participation of the Company's management, including our Chief Executive Officer and our Chief Financial Officer, of the 

effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation as of the end of 

the  period  covered  by  this  report,  the  Company's  Chief  Executive  Officer  and  Chief  Financial  Officer  concluded  that  its 

disclosure  controls  and  procedures  were  effective  to  give  reasonable  assurances  to  the  timely  collection,  evaluation  and 

disclosure of information relating to the Company that would potentially be subject to disclosure under the Exchange Act and 

the rules and regulations promulgated thereunder.

Management's Report on Internal Control over Financial Reporting

The Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such

Company's  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  the  Company  conducted  an 

evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023 based on the framework 

in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 

Commission  (2013  Framework)  (COSO).  Based  on  that  evaluation,  the  Company  concluded  that  its  internal  control  over 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 

projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate 

because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2023 has been audited by 

Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Partnership's  general  partner,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosure  based  closely  on  the 

definition  of  “disclosure  controls  and  procedures”  in  Rule  13a-15(e)  of  the  Exchange  Act.  Notwithstanding  the  foregoing,  a

the share repurchase program in the fourth quarter of 2017, second quarter of 2018, fourth quarter of 2018, fourth quarter of 

2019, and fourth quarter of 2020 bringing the total program size to $3.5 billion.

As  of  the  end  of  the  period  covered  by  this  report,  the  Operating  Partnership  carried  out  an  evaluation,  under  the 
supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer of the 
Operating  Partnership's  general  partner,  of  the  effectiveness  of  the  design  and  operation  of  the  Operating  Partnership's 
disclosure  controls  and  procedures.  Based  upon  that  evaluation  as  of  the  end  of  the  period  covered  by  this  report,  the  Chief 
Executive  Officer  and  Chief  Financial  Officer  of  the  Operating  Partnership's  general  partner  concluded  that  the  Operating 
Partnership's  disclosure  controls  and  procedures  were  effective  to  give  reasonable  assurances  to  the  timely  collection, 
evaluation  and  disclosure  of  information  relating  to  the  Operating  Partnership  that  would  potentially  be  subject  to  disclosure 
under the Exchange Act and the rules and regulations promulgated thereunder.

Management’s Report on Internal Control over Financial Reporting

The  Operating  Partnership  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting,  as  such  term  is  defined  in  Exchange  Act  Rules  13a-15  (f)  and  15d-15  (f).  Under  the  supervision  and  with  the 
participation  of  our  management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer  of  the  Operating 
Partnership's general partner, the Operating Partnership conducted an evaluation of the effectiveness of its internal control over 
financial reporting as of December 31, 2023 based on the framework in Internal Control-Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (COSO). Based on that evaluation, 
the Operating Partnership concluded that its internal control over financial reporting was effective as of December 31, 2023.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate 
because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.

The  effectiveness  of  the  Operating  Partnership's  internal  control  over  financial  reporting  as  of  December  31,  2023  has 
been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which appears 
herein.

Changes in Internal Control over Financial Reporting

There have been no significant changes in the Operating Partnership's internal control over financial reporting during the 
year ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, its internal control over 
financial reporting.

As  of  December  31,  2023,  there  were  3,949,448  units  of  limited  partnership  interest  of  the  Operating  Partnership 
outstanding and held by persons other than the Company, which received distributions per unit of the same amount and in the 
same manner as dividends per share were distributed to common stockholders.

There is no established public trading market for the common units of the Operating Partnership. On February 22, 2024, 

weighted-average exercise price calculation.

there were 52 holders of record and 69,221,575 common units outstanding, 64,799,013 of which were held by SL Green.

In order for SL Green to maintain its qualification as a REIT, it must make annual distributions to its stockholders of at 
least 90% of its taxable income (not including net capital gains). SL Green has adopted a policy of paying regular dividends on 
its common stock, and the Operating Partnership has adopted a policy of paying regular distributions to its common units in the 
same  amount  as  dividends  paid  by  SL  Green.  Cash  distributions  have  been  paid  on  the  common  stock  of  SL  Green  and  the 
common  units  of  the  Operating  Partnership  since  the  initial  public  offering  of  SL  Green.  Distributions  are  declared  at  the 
discretion  of  the  Board  of  Directors  of  SL  Green  and  depend  on  actual  and  anticipated  cash  from  operations,  financial 
condition, capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code 
and other factors SL Green’s Board of Directors may consider relevant. 

Each time SL Green issues shares of stock (other than in exchange for common units of limited partnership interest of the 
Operating  Partnership,  or  OP  Units,  when  such  OP  Units  are  presented  for  redemption),  it  contributes  the  proceeds  of  such 
issuance to the Operating Partnership in return for an equivalent number of units of limited partnership interest with rights and 
preferences analogous to the shares issued.
