Related Party Transactions	Related Party Transactions QIA Securities Purchase Agreement On August 23, 2016, we entered into a securities purchase agreement (the “Securities Purchase Agreement”) with QIA, pursuant to which QIA purchased from us 29,610,854 shares (the “Shares”) of our Class A common stock, par value $0.01 per share, at a purchase price of $21.00 per share. The Shares represented a 9.9% fully diluted economic interest in us (inclusive of all outstanding common operating partnership units and long term incentive plan units of Empire State Realty OP, L.P., our operating partnership). We received approximately $621.8 million in gross proceeds at the closing for the purchase and sale of the Shares (the “Closing”). Stockholders Agreement In connection with the sale of the Shares to QIA, we and QIA entered into a stockholders agreement, dated as of August 23, 2016 (the “Stockholders Agreement”), which sets forth certain rights and obligations of us and QIA, relating to QIA’s ownership of our Class A common stock, including the following: QIA could not transfer any Shares during the six-month period that followed the Closing, and not transfer more than 50% of the Shares during the period that began six months after the Closing and ended on the one-year anniversary of the Closing. All restrictions on transfer pursuant to the Stockholders Agreement have now lapsed. QIA has agreed to limit its voting power on all matters coming before our stockholders (whether at a meeting or by written consent) to no more than 9.9% of the total number of votes entitled to be cast on such matter. Any shares of Class A common stock held by QIA in excess of such 9.9% threshold will be voted in the same manner and proportion as the votes cast by all other stockholders on such matters. QIA granted our Board of Directors an irrevocable proxy to vote in such manner any shares of Class A common stock it holds in excess of such 9.9%. Further, QIA has agreed to vote all of its shares of Class A common stock up to the 9.9% threshold in favor of the election of each member of any slate of director nominees recommended by our Board of Directors. In connection with any new issuance by us of common equity securities, for so long as QIA maintains at least a 5.0% fully diluted economic interest in us and remains in material compliance with the terms of the Stockholders Agreement, QIA will have the right (but not the obligation) to purchase its pro rata share of such new equity securities in the form of newly issued shares of Class A common stock. These “top up” rights are generally exercisable on a quarterly basis, or sooner if we or the operating partnership issues new equity securities in an issuance in excess of $1.0 million. For an initial period of five years from the date of the Closing, to the extent QIA remains in material compliance with the terms of the Stockholders Agreement, QIA will have the right of first offer to co-invest with us as a joint venture partner in real estate investment opportunities initiated by us where we have elected, at our discretion, to seek a joint venture partner. The right of first offer period will be extended for a 30-month term if at least one joint venture transaction is consummated among us and QIA during the initial five-year term, and will be extended for a further 30-month term if at least one joint venture transaction is consummated during such initial 30-month extension term. Subject to certain minimum thresholds and conditions, we will indemnify QIA for certain applicable U.S. federal and state taxes payable by QIA in connection with dividends paid by us on the Shares (and any “top up” shares) that are attributable to capital gains from the sale or exchange of any U.S. real property interests. Our obligation to indemnify QIA will terminate one year following the date on which the sum of the Shares and any “top up” shares then owned by QIA falls below 10% of our outstanding common shares. Registration Rights Agreement In connection with the sale of the Shares to QIA, we and QIA entered into a registration rights agreement, dated as of August 23, 2016 (the “Registration Rights Agreement”), which required us, among other things, to file with the SEC within 180 days following the Closing, a resale shelf registration statement providing for the resale of the Shares. We filed the resale shelf registration statement with the SEC on February 2, 2017 and renewed it on August 3, 2017. In addition, QIA will be entitled to cause us to include in the registration statement such additional “top up” shares of Class A common stock as QIA may acquire from time to time in the future, up to a 9.9% fully diluted economic interest in us. The registration rights are subject to certain conditions and limitations, including restrictions on sales of shares by the holder in connection with certain public offerings and our right to delay or withdraw a registration statement under certain circumstances. We will generally pay all registration expenses in connection with our obligations under the Registration Rights Agreement. Tax Protection Agreement In 2013, we entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin that is intended to protect to a limited extent the Malkin Group and an additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain tax consequences arising from a transaction involving one of four properties, which we refer to in this section as the protected assets. First, this agreement provides that our operating partnership will not sell, exchange, transfer or otherwise dispose of such protected assets, or any interest in a protected asset, until (i) October 7, 2025, with respect to one protected asset, First Stamford Place, and (ii) the later of (x) October 7, 2021 and (y) the death of both Peter L. Malkin and Isabel W. Malkin, who are 84 and 81 years old, respectively, for the three other protected assets, Metro Center, 10 Bank Street and 1542 Third Avenue, unless: (1)Anthony E. Malkin consents to the sale, exchange, transfer or other disposition; or (2)our operating partnership delivers to each protected party thereunder a cash payment intended to approximate the tax liability arising from the recognition of the pre-contribution built-in gain resulting from the sale, exchange, transfer or other disposition of such protected asset (with the pre-contribution “built-in gain” being not more than the taxable gain that would have been recognized by such protected party if the protected asset been sold for fair market value in a taxable transaction at the time of the consolidation) plus an additional amount so that, after the payment of all taxes on amounts received pursuant to the agreement (including any tax liability incurred as a result of receiving such payment), the protected party retains an amount equal to such protected party’s total tax liability incurred as a result of the recognition of the pre-contribution built-in gain pursuant to such sale, exchange, transfer or other disposition; or (3)the disposition does not result in a recognition of any built-in gain by the protected party. Second, with respect to the Malkin Group, including Anthony E. Malkin and Peter L. Malkin, and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property), to protect against gain recognition resulting from a reduction in such continuing investor’s share of the operating partnership liabilities, the agreement provides that during the period from October 7, 2013 until such continuing investor owns less than the aggregate number of operating partnership units and shares of common stock equal to 50% of the aggregate number of such units and shares such investor received in the formation transactions, which we refer to in this section as the tax protection period, our operating partnership will (i) refrain from prepaying any amounts outstanding under any indebtedness secured by the protected assets and (ii) use its commercially reasonable efforts to refinance such indebtedness at or prior to maturity at its current principal amount, or, if our operating partnership is unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible. The agreement also provides that, during the tax protection period, our operating partnership will make available to such continuing investors the opportunity (i) to enter into a “bottom dollar” guarantee of their allocable share of $160.0 million of aggregate indebtedness of our operating partnership meeting certain requirements or (ii) in the event our operating partnership has recourse debt outstanding and such a continuing investor agrees, in lieu of guaranteeing debt pursuant to clause (i) above, to enter into a deficit restoration obligation, in each case, in a manner intended to provide an allocation of operating partnership liabilities to the continuing investor. In the event that a continuing investor guarantees debt of our operating partnership, such continuing investor will be responsible, under certain circumstances, for the repayment of the guaranteed amount to the lender in the event that the lender would otherwise recognize a loss on the loan, such as, for example, if property securing the loan was foreclosed and the value was not sufficient to repay a certain amount of the debt. A deficit restoration obligation is a continuing investor’s obligation, under certain circumstances, to contribute a designated amount of capital to our operating partnership upon our operating partnership’s liquidation in the event that the assets of our operating partnership are insufficient to repay our operating partnership liabilities. Because we expect that our operating partnership will at all times have sufficient liabilities to allow it to meet its obligations to allocate liabilities to its partners that are protected parties under the tax protection agreement, our operating partnership’s indemnification obligation with respect to “certain tax liabilities” would generally arise only in the event that the operating partnership disposes in a taxable transaction of a protected asset within the period specified above in a taxable transaction. In the event of such a disposition, the amount of our operating partnership’s indemnification obligation would depend on several factors, including the amount of “built-in gain,” if any, recognized and allocated to the indemnified partners with respect to such disposition and the effective tax rate to be applied to such gain at the time of such disposition. The operating partnership agreement requires that allocations with respect to such acquired property be made in a manner consistent with Section 704(c) of the Code. Treasury Regulations issued under Section 704(c) of the Code provide partnerships with a choice of several methods of allocating book-tax differences. Under the tax protection agreement, our operating partnership has agreed to use the “traditional method” for accounting for book-tax differences for the properties acquired by our operating partnership in the consolidation. Under the traditional method, which is the least favorable method from our perspective, the carryover basis of the acquired properties in the hands of our operating partnership (i) may cause us to be allocated lower amounts of depreciation and other deductions for tax purposes than would be allocated to us if all of the acquired properties were to have a tax basis equal to their fair market value at the time of acquisition and (ii) in the event of a sale of such properties, could cause us to be allocated gain in excess of its corresponding economic or book gain (or taxable loss that is less than its economic or book loss), with a corresponding benefit to the partners transferring such properties to our operating partnership for interests in our operating partnership. Registration Rights We entered into a registration rights agreement with certain persons receiving shares of our common stock or operating partnership units in the formation transactions, including certain members of our senior management team and our other continuing investors. In connection therewith, we have filed, and are obligated to maintain the effectiveness of, an automatically effective shelf registration statement, along with a prospectus supplement, with respect to, among other things, shares of our Class A common stock that may be issued upon redemption of operating partnership units or issued upon conversion of shares of Class B common stock to continuing investors in the public existing entities. Pursuant to the registration rights agreement, under certain circumstances, we will also be required to undertake an underwritten offering upon the written request of the Malkin Group, which we refer to as the holder, provided (i) the registrable shares to be registered in such offering will have a market value of at least $150.0 million, (ii) we will not be obligated to effect more than two underwritten offerings during any 12-month period; and (iii) the holder will not have the ability to effect more than four underwritten offerings. In addition, if we file a registration statement with respect to an underwritten offering for our own account or on behalf of the holder, the holder will have the right, subject to certain limitations, to register such number of registrable shares held by him, her or it as each such holder requests. With respect to underwritten offerings on behalf of the holder, we will have the right to register such number of primary shares as we request; provided, however, that if cut backs are required by the managing underwriters of such an offering, our primary shares shall be cutback first (but in no event will our shares be cut back to less than $25.0 million). We have also agreed to indemnify the persons receiving rights against specified liabilities, including certain potential liabilities arising under the Securities Act, or to contribute to the payments such persons may be required to make in respect thereof. We have agreed to pay all of the expenses relating to the registration and any underwritten offerings of such securities, including, without limitation, all registration, listing, filing and stock exchange or FINRA fees, all fees and expenses of complying with securities or “blue sky” laws, all printing expenses and all fees and disbursements of counsel and independent public accountants retained by us, but excluding underwriting discounts and commissions, any out-of-pocket expenses (except we will pay any holder’s out-of-pocket fees (including disbursements of such holder’s counsel, accountants and other advisors) up to $25,000 in the aggregate for each underwritten offering and each filing of a resale shelf registration statement or demand registration statement), and any transfer taxes. Employment Agreement and Change in Control Severance Agreements We entered into an employment agreement with Anthony E. Malkin, which provides for salary, bonuses and other benefits, including among other things, severance benefits upon a termination of employment under certain circumstances and the issuance of equity awards. In addition, we entered into change in control severance agreements with Thomas P. Durels, David A. Karp, Thomas N. Keltner, Jr. and John B. Kessler. Indemnification of Our Directors and Officers We entered into indemnification agreements with each of our directors, executive officers, chairman emeritus and certain other parties, providing for the indemnification by us for certain liabilities and expenses incurred as a result of actions brought, or threatened to be brought, against (i) our directors, executive officers and chairman emeritus and (ii) our executive officers, chairman emeritus and certain other parties who are former members, managers, securityholders, directors, limited partners, general partners, officers or controlling persons of our predecessor in such capacities. Excluded Properties and Businesses The Malkin Group, including Anthony E. Malkin, our Chairman and Chief Executive Officer, owns non-controlling interests in, and Anthony E. Malkin and Peter L. Malkin control the general partners or managers of, the entities that own interests in seven multi-family properties, five net leased retail properties, (including one single tenant retail property in Greenwich, Connecticut), and a parcel that is being developed for residential use. The Malkin Group also owns non-controlling interests in one Manhattan office property, two Manhattan retail properties and several retail properties outside of Manhattan, none of which were contributed to us in the formation transactions. We refer to the non-controlling interests described above collectively as the excluded properties. In addition, the Malkin Group owns interests in two mezzanine and senior equity funds, an industrial fund, and five residential properties, and which we refer to collectively as the excluded businesses. Other than the Greenwich retail property, we do not believe that the excluded properties or the excluded businesses are consistent with our portfolio geographic or property type composition, management or strategic direction. Pursuant to management and/or service agreements with the owners of interests in those excluded properties and services agreements with the five residential property managers and the managers of certain other excluded businesses which historically were managed by affiliates of our predecessor, we are designated as the asset manager (supervisor) and/or property manager of the excluded properties and will provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses. As the manager or service provider, we are paid a management or other fee with respect to those excluded properties and excluded businesses where our predecessor had previously received a management fee on the same terms as the fee paid to our predecessor, and reimbursed for our costs in providing the management and other services to those excluded properties and businesses where our predecessor had not previously received a management fee. Our management of the excluded properties and provision of services to the five residential property managers and the existing managers of the other excluded businesses represent a minimal portion of our overall business. There is no established time period in which we will manage such properties or provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses; and Peter L. Malkin and Anthony E. Malkin expect to sell certain of these properties or unwind certain of these businesses over time. We are not precluded from acquiring all or certain interests in the excluded properties or businesses. If we were to attempt any such acquisition, we anticipate that Anthony E. Malkin, our Chairman and Chief Executive Officer, will not participate in the negotiation process on our behalf with respect to our potential acquisition of any of these excluded properties or businesses, and the approval of a majority of our independent directors will be required to approve any such acquisition. Services are and were provided by us to excluded properties and businesses. These transactions are reflected in our consolidated statements of income as third-party management and other fees. We earned asset management (supervisory) and service fees from excluded properties and businesses of $1.1 million, $1.4 million and $1.8 million during the years ended December 31, 2017, 2016 and 2015, respectively. We earned property management fees from excluded properties of $0.3 million, $0.4 million and $0.3 million during the years ended December 31, 2017, 2016 and 2015, respectively. Other We were reimbursed at allocable cost for 647 square feet of shared office space, equipment, and administrative support shared with us in our corporate offices, as was done prior to our formation, and we received rent generally at market rental rate for 3,074 square feet of leased space, from entities affiliated with Anthony E. Malkin at one of our properties. Total revenue aggregated $0.2 million and $0.2 million, for the years ended December 31, 2016 and 2015, respectively. During August 2016, such entities moved from the previously shared office and leased spaces to relocate to a new 5,351 square foot leased space at one of our properties, paying rent generally at a market rental rate. Under such new lease, the tenant has the right to cancel such lease without special payment on 90 days’ notice. We now have a shared use agreement with such tenant, to occupy a portion of the leased premises as the office location for Peter L. Malkin, our chairman emeritus and employee, utilizing approximately 15% of the space, for which we pay an allocable pro rata share of the cost to such tenant. We also have agreements with these entities and excluded properties and businesses to provide them with general computer-related support. Total revenue aggregated $0.4 million and $0.1 million for the years ended December 31, 2017 and 2016, respectively. During 2016 and in connection with our office move, Peter L. Malkin purchased miscellaneous furniture and artwork from us at their appraised value of $23,300. Remaining office furniture was disposed. One of our directors, James D. Robinson IV, is a general partner in an investment fund, which owns more than a 10% economic and voting interest in one of our tenants, OnDeck Capital, with an annualized rent of $5.8 million and $5.7 million as of December 31, 2017 and 2016, respectively.

QIA

Securities Purchase Agreement

On August 23, 2016, we entered into a securities purchase agreement (the “Securities Purchase Agreement”) with QIA, pursuant to which QIA purchased from us 29,610,854 shares (the “Shares”) of our Class A common stock, par value $0.01 per share, at a purchase price of $21.00 per share. The Shares represented a 9.9% fully diluted economic interest in us (inclusive of all outstanding common operating partnership units and long term incentive plan units of Empire State Realty OP, L.P., our operating partnership).

We received approximately $621.8 million in gross proceeds at the closing for the purchase and sale of the Shares (the “Closing”).

Stockholders Agreement

In connection with the sale of the Shares to QIA, we and QIA entered into a stockholders agreement, dated as of August 23, 2016 (the “Stockholders Agreement”), which sets forth certain rights and obligations of us and QIA, relating to QIA’s ownership of our Class A common stock, including the following:

QIA could not transfer any Shares during the six-month period that followed the Closing, and not transfer more than 50% of the Shares during the period that began six months after the Closing and ended on the one-year anniversary of the Closing. All restrictions on transfer pursuant to the Stockholders Agreement have now lapsed.

QIA has agreed to limit its voting power on all matters coming before our stockholders (whether at a meeting or by written consent) to no more than 9.9% of the total number of votes entitled to be cast on such matter. Any shares of Class A common stock held by QIA in excess of such 9.9% threshold will be voted in the same manner and proportion as the votes cast by all other stockholders on such matters. QIA granted our Board of Directors an irrevocable proxy to vote in such manner any shares of Class A common stock it holds in excess of such 9.9%. Further, QIA has agreed to vote all of its shares of Class A common stock up to the 9.9% threshold in favor of the election of each member of any slate of director nominees recommended by our Board of Directors.

In connection with any new issuance by us of common equity securities, for so long as QIA maintains at least a 5.0% fully diluted economic interest in us and remains in material compliance with the terms of the Stockholders Agreement, QIA will have the right (but not the obligation) to purchase its pro rata share of such new equity securities in the form of newly issued shares of Class A common stock. These “top up” rights are generally exercisable on a quarterly basis, or sooner if we or the operating partnership issues new equity securities in an issuance in excess of $1.0 million.

For an initial period of five years from the date of the Closing, to the extent QIA remains in material compliance with the terms of the Stockholders Agreement, QIA will have the right of first offer to co-invest with us as a joint venture partner in real estate investment opportunities initiated by us where we have elected, at our discretion, to seek a joint venture partner. The right of first offer period will be extended for a 30-month term if at least one joint venture transaction is consummated among us and QIA during the initial five-year term, and will be extended for a further 30-month term if at least one joint venture transaction is consummated during such initial 30-month extension term.

Subject to certain minimum thresholds and conditions, we will indemnify QIA for certain applicable U.S. federal and state taxes payable by QIA in connection with dividends paid by us on the Shares (and any “top up” shares) that are attributable to capital gains from the sale or exchange of any U.S. real property interests. Our obligation to indemnify QIA will terminate one year following the date on which the sum of the Shares and any “top up” shares then owned by QIA falls below 10% of our outstanding common shares.

Registration Rights Agreement

In connection with the sale of the Shares to QIA, we and QIA entered into a registration rights agreement, dated as of August 23, 2016 (the “Registration Rights Agreement”), which required us, among other things, to file with the SEC within 180 days following the Closing, a resale shelf registration statement providing for the resale of the Shares. We filed the resale shelf registration statement with the SEC on February 2, 2017 and renewed it on August 3, 2017. In addition, QIA will be entitled to cause us to include in the registration statement such additional “top up” shares of Class A common stock as QIA may acquire from time to time in the future, up to a 9.9% fully diluted economic interest in us. The registration rights are subject to certain conditions and limitations, including restrictions on sales of shares by the holder in connection with certain public offerings and our right to delay or withdraw a registration statement under certain circumstances. We will generally pay all registration expenses in connection with our obligations under the Registration Rights Agreement.

Tax Protection Agreement

In 2013, we entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin that is intended to protect to a limited extent the Malkin Group and an additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain tax consequences arising from a transaction involving one of four properties, which we refer to in this section as the protected assets.

First, this agreement provides that our operating partnership will not sell, exchange, transfer or otherwise dispose of such protected assets, or any interest in a protected asset, until (i) October 7, 2025, with respect to one protected asset, First Stamford Place, and (ii) the later of (x) October 7, 2021 and (y) the death of both Peter L. Malkin and Isabel W. Malkin, who are 84 and 81 years old, respectively, for the three other protected assets, Metro Center, 10 Bank Street and 1542 Third Avenue, unless:

(1)Anthony E. Malkin consents to the sale, exchange, transfer or other disposition; or

(2)our operating partnership delivers to each protected party thereunder a cash payment intended to approximate the tax liability arising from the recognition of the pre-contribution built-in gain resulting from the sale, exchange, transfer or other disposition of such protected asset (with the pre-contribution “built-in gain” being not more than the taxable gain that would have been recognized by such protected party if the protected asset been sold for fair market value in a taxable transaction at the time of the consolidation) plus an additional amount so that, after the payment of all taxes on amounts received pursuant to the agreement (including any tax liability incurred as a result of receiving such payment), the protected party retains an amount equal to such protected party’s total tax liability incurred as a result of the recognition of the pre-contribution built-in gain pursuant to such sale, exchange, transfer or other disposition; or

(3)the disposition does not result in a recognition of any built-in gain by the protected party.

Second, with respect to the Malkin Group, including Anthony E. Malkin and Peter L. Malkin, and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property), to protect against gain recognition resulting from a reduction in such continuing investor’s share of the operating partnership liabilities, the agreement provides that during the period from October 7, 2013 until such continuing investor owns less than the aggregate number of operating partnership units and shares of common stock equal to 50% of the aggregate number of such units and shares such investor received in the formation transactions, which we refer to in this section as the tax protection period, our operating partnership will (i) refrain from prepaying any amounts outstanding under any indebtedness secured by the protected assets and (ii) use its commercially reasonable efforts to refinance such indebtedness at or prior to maturity at its current principal amount, or, if our operating partnership is unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible. The agreement also provides that, during the tax protection period, our operating partnership will make available to such continuing investors the opportunity (i) to enter into a “bottom dollar” guarantee of their allocable share of $160.0 million of aggregate indebtedness of our operating partnership meeting certain requirements or (ii) in the event our operating partnership has recourse debt outstanding and such a continuing investor agrees, in lieu of guaranteeing debt pursuant to clause (i) above, to enter into a deficit restoration obligation, in each case, in a manner intended to provide an allocation of operating partnership liabilities to the continuing investor. In the event that a continuing investor guarantees debt of our operating partnership, such continuing investor will be responsible, under certain circumstances, for the repayment of the guaranteed amount to the lender in the event that the lender would otherwise recognize a loss on the loan, such as, for example, if property securing the loan was foreclosed and the value was not sufficient to repay a certain amount of the debt. A deficit restoration obligation is a continuing investor’s obligation, under certain circumstances, to contribute a designated amount of capital to our operating partnership upon our operating partnership’s liquidation in the event that the assets of our operating partnership are insufficient to repay our operating partnership liabilities.

Because we expect that our operating partnership will at all times have sufficient liabilities to allow it to meet its obligations to allocate liabilities to its partners that are protected parties under the tax protection agreement, our operating partnership’s indemnification obligation with respect to “certain tax liabilities” would generally arise only in the event that the operating partnership disposes in a taxable transaction of a protected asset within the period specified above in a taxable transaction. In the event of such a disposition, the amount of our operating partnership’s indemnification obligation would depend on several factors, including the amount of “built-in gain,” if any, recognized and allocated to the indemnified partners with respect to such disposition and the effective tax rate to be applied to such gain at the time of such disposition.

The operating partnership agreement requires that allocations with respect to such acquired property be made in a manner consistent with Section 704(c) of the Code. Treasury Regulations issued under Section 704(c) of the Code provide partnerships with a choice of several methods of allocating book-tax differences. Under the tax protection agreement, our operating partnership has agreed to use the “traditional method” for accounting for book-tax differences for the properties acquired by our operating partnership in the consolidation. Under the traditional method, which is the least favorable method from our perspective, the carryover basis of the acquired properties in the hands of our operating partnership (i) may cause us to be allocated lower amounts of depreciation and other deductions for tax purposes than would be allocated to us if all of the acquired properties were to have a tax basis equal to their fair market value at the time of acquisition and (ii) in the event of a sale of such properties, could cause us to be allocated gain in excess of its corresponding economic or book gain (or taxable loss that is less than its economic or book loss), with a corresponding benefit to the partners transferring such properties to our operating partnership for interests in our operating partnership.

Registration Rights

We entered into a registration rights agreement with certain persons receiving shares of our common stock or operating partnership units in the formation transactions, including certain members of our senior management team and our other continuing investors. In connection therewith, we have filed, and are obligated to maintain the effectiveness of, an automatically effective shelf registration statement, along with a prospectus supplement, with respect to, among other things, shares of our Class A common stock that may be issued upon redemption of operating partnership units or issued upon conversion of shares of Class B common stock to continuing investors in the public existing entities. Pursuant to the registration rights agreement, under certain circumstances, we will also be required to undertake an underwritten offering upon the written request of the Malkin Group, which we refer to as the holder, provided (i) the registrable shares to be registered in such offering will have a market value of at least $150.0 million, (ii) we will not be obligated to effect more than two underwritten offerings during any 12-month period; and (iii) the holder will not have the ability to effect more than four underwritten offerings. In addition, if we file a registration statement with respect to an underwritten offering for our own account or on behalf of the holder, the holder will have the right, subject to certain limitations, to register such number of registrable shares held by him, her or it as each such holder requests. With respect to underwritten offerings on behalf of the holder, we will have the right to register such number of primary shares as we request; provided, however, that if cut backs are required by the managing underwriters of such an offering, our primary shares shall be cutback first (but in no event will our shares be cut back to less than $25.0 million).

We have also agreed to indemnify the persons receiving rights against specified liabilities, including certain potential liabilities arising under the Securities Act, or to contribute to the payments such persons may be required to make in respect thereof. We have agreed to pay all of the expenses relating to the registration and any underwritten offerings of such securities, including, without limitation, all registration, listing, filing and stock exchange or FINRA fees, all fees and expenses of complying with securities or “blue sky” laws, all printing expenses and all fees and disbursements of counsel and independent public accountants retained by us, but excluding underwriting discounts and commissions, any out-of-pocket expenses (except we will pay any holder’s out-of-pocket fees (including disbursements of such holder’s counsel, accountants and other advisors) up to $25,000 in the aggregate for each underwritten offering and each filing of a resale shelf registration statement or demand registration statement), and any transfer taxes.

Employment Agreement and Change in Control Severance Agreements

We entered into an employment agreement with Anthony E. Malkin, which provides for salary, bonuses and other benefits, including among other things, severance benefits upon a termination of employment under certain circumstances and the issuance of equity awards. In addition, we entered into change in control severance agreements with Thomas P. Durels, David A. Karp, Thomas N. Keltner, Jr. and John B. Kessler.

Indemnification of Our Directors and Officers

We entered into indemnification agreements with each of our directors, executive officers, chairman emeritus and certain other parties, providing for the indemnification by us for certain liabilities and expenses incurred as a result of actions brought, or threatened to be brought, against (i) our directors, executive officers and chairman emeritus and (ii) our executive officers, chairman emeritus and certain other parties who are former members, managers, securityholders, directors, limited partners, general partners, officers or controlling persons of our predecessor in such capacities.

Excluded Properties and Businesses

The Malkin Group, including Anthony E. Malkin, our Chairman and Chief Executive Officer, owns non-controlling interests in, and Anthony E. Malkin and Peter L. Malkin control the general partners or managers of, the entities that own interests in seven multi-family properties, five net leased retail properties, (including one single tenant retail property in Greenwich, Connecticut), and a parcel that is being developed for residential use. The Malkin Group also owns non-controlling interests in one Manhattan office property, two Manhattan retail properties and several retail properties outside of Manhattan, none of which were contributed to us in the formation transactions. We refer to the non-controlling interests described above collectively as the excluded properties. In addition, the Malkin Group owns interests in two mezzanine and senior equity funds, an industrial fund, and five residential properties, and which we refer to collectively as the excluded businesses. Other than the Greenwich retail property, we do not believe that the excluded properties or the excluded businesses are consistent with our portfolio geographic or property type composition, management or strategic direction.

Pursuant to management and/or service agreements with the owners of interests in those excluded properties and services agreements with the five residential property managers and the managers of certain other excluded businesses which historically were managed by affiliates of our predecessor, we are designated as the asset manager (supervisor) and/or property manager of the excluded properties and will provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses. As the manager or service provider, we are paid a management or other fee with respect to those excluded properties and excluded businesses where our predecessor had previously received a management fee on the same terms as the fee paid to our predecessor, and reimbursed for our costs in providing the management and other services to those excluded properties and businesses where our predecessor had not previously received a management fee. Our management of the excluded properties and provision of services to the five residential property managers and the existing managers of the other excluded businesses represent a minimal portion of our overall business. There is no established time period in which we will manage such properties or provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses; and Peter L. Malkin and Anthony E. Malkin expect to sell certain of these properties or unwind certain of these businesses over time. We are not precluded from acquiring all or certain interests in the excluded properties or businesses. If we were to attempt any such acquisition, we anticipate that Anthony E. Malkin, our Chairman and Chief Executive Officer, will not participate in the negotiation process on our behalf with respect to our potential acquisition of any of these excluded properties or businesses, and the approval of a majority of our independent directors will be required to approve any such acquisition.

Services are and were provided by us to excluded properties and businesses. These transactions are reflected in our consolidated statements of income as third-party management and other fees.

We earned asset management (supervisory) and service fees from excluded properties and businesses of $1.1 million, $1.4 million and $1.8 million during the years ended December 31, 2017, 2016 and 2015, respectively.

We earned property management fees from excluded properties of $0.3 million, $0.4 million and $0.3 million during the years ended December 31, 2017, 2016 and 2015, respectively.

We were reimbursed at allocable cost for 647 square feet of shared office space, equipment, and administrative support shared with us in our corporate offices, as was done prior to our formation, and we received rent generally at market rental rate for 3,074 square feet of leased space, from entities affiliated with Anthony E. Malkin at one of our properties. Total revenue aggregated $0.2 million and $0.2 million, for the years ended December 31, 2016 and 2015, respectively.

During August 2016, such entities moved from the previously shared office and leased spaces to relocate to a new 5,351 square foot leased space at one of our properties, paying rent generally at a market rental rate. Under such new lease, the tenant has the right to cancel such lease without special payment on 90 days’ notice. We now have a shared use agreement with such tenant, to occupy a portion of the leased premises as the office location for Peter L. Malkin, our chairman emeritus and employee, utilizing approximately 15% of the space, for which we pay an allocable pro rata share of the cost to such tenant. We also have agreements with these entities and excluded properties and businesses to provide them with general computer-related support. Total revenue aggregated $0.4 million and $0.1 million for the years ended December 31, 2017 and 2016, respectively.

During 2016 and in connection with our office move, Peter L. Malkin purchased miscellaneous furniture and artwork from us at their appraised value of $23,300. Remaining office furniture was disposed.

One of our directors, James D. Robinson IV, is a general partner in an investment fund, which owns more than a 10% economic and voting interest in one of our tenants, OnDeck Capital, with an annualized rent of $5.8 million and $5.7 million as of December 31, 2017 and 2016, respectively.
