8. Equity

During the six months ended June 30, 2019, Simon issued 24,000 shares of common stock to a limited partner of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership. During the six months ended June 30, 2019, the Operating Partnership redeemed 774 units from three limited partners for $0.1 million. These transactions increased Simon’s ownership interest in the Operating Partnership.

On February 13, 2017, Simon’s Board of Directors authorized a two-year extension of the previously authorized $2.0 billion common stock repurchase plan through March 31, 2019. On February 11, 2019, Simon's Board of Directors authorized a new common stock repurchase plan. Under the new plan, Simon may repurchase up to $2.0 billion of its common stock during the two-year period ending February 11, 2021 in the open market or in privately negotiated transactions as market conditions warrant. During the six months ended June 30, 2019, Simon purchased 1,092,957 shares at an average price of $165.84 per share, of which 46,377 shares at an average price of $164.49 were purchased as part of the previous program. In July 2019, Simon purchased 633,780 shares at an average price of $157.78 per share. During the six months ended June 30, 2018, Simon purchased 1,988,247 shares at an average price of $154.56 per share as part of the previous program. As Simon repurchases shares under these programs, the Operating Partnership repurchases an equal number of units from Simon.

We paid a common stock dividend of $2.05 per share in the second quarter of 2019 and $4.10 per share for the six months ended June 30, 2019. The Operating Partnership paid distributions per unit for the same amounts. We paid dividends of $1.95 and $3.90 per share for the three and six months ended June 30, 2018. The Operating Partnership paid distributions per unit for

the same amounts. Simon’s Board of Directors declared a quarterly cash dividend for the third quarter of 2019 of $2.10 per share of common stock payable on August 30, 2019 to stockholders of record on August 16, 2019. The distribution rate on units is equal to the dividend rate on common stock.

Temporary Equity

Simon

Simon classifies as temporary equity those securities for which there is the possibility that Simon could be required to redeem the security for cash irrespective of the probability of such a possibility. As a result, Simon classifies one series of preferred units in the Operating Partnership and noncontrolling redeemable interests in properties in temporary equity. Each of these securities is discussed further below.

Limited Partners’ Preferred Interest in the Operating Partnership and Noncontrolling Redeemable Interests in Properties. The redemption features of the preferred units in the Operating Partnership contain provisions which could require the Operating Partnership to settle the redemption in cash. As a result, this series of preferred units in the Operating Partnership remains classified outside permanent equity. The remaining interests in a property or portfolio of properties which are redeemable at the option of the holder or in circumstances that may be outside Simon’s control are accounted for as temporary equity. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit in the consolidated statements of equity in issuance of unit equivalents and other. There were no noncontrolling interests redeemable at amounts in excess of fair value as of June 30, 2019 and December 31, 2018. The following table summarizes the preferred units in the Operating Partnership and the amount of the noncontrolling redeemable interests in properties as follows:


	As of		As of
	June 30,		December 31,
	2019		2018
7.50% Cumulative Redeemable Preferred Units, 260,000 units authorized, 255,373 issued and outstanding	$	25,537	$	25,537
Other noncontrolling redeemable interests in properties		205,788		204,626
Limited partners’ preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties	$	231,325	$	230,163

The Operating Partnership

The Operating Partnership classifies as temporary equity those securities for which there is the possibility that the Operating Partnership could be required to redeem the security for cash, irrespective of the probability of such a possibility. As a result, the Operating Partnership classifies one series of preferred units and noncontrolling redeemable interests in properties in temporary equity. The following table summarizes the preferred units and the amount of the noncontrolling redeemable interests in properties as follows:


	As of		As of
	June 30,		December 31,

Stock Based Compensation

Awards under our stock based compensation plans primarily take the form of LTIP unit and restricted stock grants. Restricted stock and awards under the LTIP programs contain both market and performance conditions, which are based on various individual, corporate and business unit performance measures as further described below. The expense related to these programs, net of amounts capitalized, is included within home and regional office costs and general and administrative costs in the accompanying statements of operations and comprehensive income.

LTIP Programs. The Compensation Committee has approved long-term, performance based incentive compensation programs, or the LTIP programs, for certain senior employees. Awards under the LTIP programs take the form of LTIP units, a form of limited partnership interest issued by the Operating Partnership, which are subject to the participant maintaining employment with us through certain dates and other conditions as described in the applicable award agreements. Awarded LTIP units not earned in accordance with the conditions set forth in the applicable award agreements are forfeited. Earned and fully vested LTIP units are equivalent to units of the Operating Partnership. During the performance period, participants are entitled to receive distributions on the LTIP units awarded to them equal to 10% of the regular quarterly distributions paid on a unit of the Operating Partnership. As a result, we account for these LTIP units as participating securities under the two-class method of computing earnings per share.

In 2019, the Compensation Committee established and granted awards under a redesigned LTIP program, or the 2019 LTIP program. Awards under the 2019 LTIP program will be considered earned if, and only to the extent to which, the respective performance conditions (based on Funds From Operations, or FFO, per share, and Objective Criteria Goals) and market conditions (based on Relative TSR performance), as defined in the applicable award agreements, are achieved during the applicable three-year measurement period, subject to the recipient’s continued employment through the vesting date. All of the earned LTIP units under the 2019 LTIP program will vest on January 1, 2023. The 2019 LTIP program provides that the amount earned of the performance-based portion of the awards is dependent on Simon’s performance compared to certain criteria and has a maximum potential fair value at issuance of $22.1 million.

The grant date fair values of any LTIP units for market-based awards are estimated using a Monte Carlo model, and the resulting fixed expense is recorded regardless of whether the market condition criteria are achieved if the required service is delivered. The grant date fair values of the market-based awards are being amortized into expense over the period from the grant date to the date at which the awards, if earned, would become vested. The level of expense of the performance-based award is recorded over the period from the grant date to the date at which the awards, if earned, would become vested, based on our assessment as to whether it is probable that the performance criteria will be achieved during the applicable performance periods.

The Compensation Committee approved LTIP unit grants as shown in the table below. The extent to which LTIP units were earned, and the aggregate grant date fair value, are as follows:


LTIP Program	LTIP Units Earned	Grant Date Fair Value of TSR Award	Grant Date Target Value of Performance-Based Awards

We recorded compensation expense, net of capitalization, related to these LTIP programs of approximately $8.1 million and $8.6 million for the six months ended June 30, 2019 and 2018, respectively.

Restricted Stock. The Compensation Committee awarded 82,969 shares of restricted stock to employees during the six months ended June 30, 2019 at a weighted-average fair market value of $182.21 per share. During the six months ended June 30, 2019, our non-employee Directors were awarded 10,644 shares of restricted stock at a weighted average fair market value of $174.03 per share. These shares represent a portion of the compensation we pay our non-employee Directors, and all of the shares have been placed in a non-employee Director deferred compensation account maintained by us. The grant date fair value of the employee restricted stock awards is being recognized as expense over the three-year vesting service period. The grant date fair value of the non-employee Director restricted stock awards is being recognized as expense over the one-year vesting service period. In accordance with the Operating Partnership's partnership agreement, the Operating Partnership issued an equal number of units to Simon that are subject to the same vesting conditions as the restricted stock.

We recorded compensation expense, net of capitalization, related to restricted stock of approximately $3.8 million and $4.0 million for the six months ended June 30, 2019 and 2018, respectively.

Other Compensation Arrangements. On July 6, 2011, in connection with the execution of an employment agreement, the Compensation Committee granted David Simon, Simon’s Chairman, Chief Executive Officer and President, a retention award in the form of 1,000,000 LTIP units, or the Award, for his continued service through July 5, 2019. Effective December 31, 2013, the Award was modified, or the Current Award, and as a result the LTIP units would become earned and eligible to vest based on the attainment of Company-based performance goals, in addition to the service-based vesting requirement included in the original Award. The Current Award does not contain an opportunity for Mr. Simon to receive additional LTIP units above and beyond the original Award should our performance exceed the higher end of the performance criteria. The performance criteria of the Current Award are based on the attainment of specific FFO per share goals. Because the performance criteria has been met, a maximum of 360,000 LTIP units, or the A units, 360,000 LTIP units, or the B units, and 280,000 LTIP units, or the C units, became earned on December 31, 2015, December 31, 2016 and December 31, 2017, respectively. If the relevant performance criteria had not been achieved, all or a portion of the Current Award would have been forfeited. The earned A units vested on January 1, 2018, earned B units vested on January 1, 2019 and earned C units vested on June 30, 2019. The grant date fair value of the retention award of $120.3 million was recognized as expense over the eight-year term of his employment agreement on a straight-line basis based on the applicable vesting periods of the A units, B units and C units.

Significant Accounting Policies (Policies)

Significant Accounting Policies

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers’ acceptances, Eurodollars, repurchase agreements, and money market deposits or securities. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions of high credit quality. However, at certain times, such cash and cash equivalents are in excess of Federal Deposit Insurance Corporation and Securities Investor Protection Corporation insurance limits.

Equity Instruments and Debt Securities

Equity instruments and debt securities consist primarily of the debt securities of our captive insurance subsidiary, equity instruments, our deferred compensation plan investments, and certain investments held to fund the debt service requirements of debt previously secured by investment properties. At June 30, 2019 and December 31, 2018, we had equity instruments with readily determinable fair values of $74.1 million and $78.1 million, respectively. Effective January 1, 2018, changes in fair value of these equity instruments are recorded in earnings. We recognized a cumulative effect adjustment of $7.3 million as of January 1, 2018 to reclassify unrealized gains previously reported in accumulated other comprehensive income as a result of the adoption of Accounting Standards Update (ASU) 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” Non-cash mark-to-market adjustments related to an investment we hold in units of a publicly traded real estate investment trust are included in unrealized (losses) gains in fair value of equity instruments in our consolidated statements of operations and comprehensive income. Non-cash mark-to-market adjustments related to other securities with readily determinable fair values for the three and six months ended June 30, 2019 and 2018 were not significant. At June 30, 2019 and December 31, 2018, we had equity instruments without readily determinable fair values of $187.5 million and $175.7 million, respectively, for which we have elected the measurement alternative under this guidance. We regularly evaluate these investments for any impairment in their estimated fair value, as well as any observable price changes for an identical or similar equity instrument of the same issuer, and determined that no material adjustment in the carrying value was required for the three or six months ended June 30, 2019 and 2018.

Our deferred compensation plan equity instruments are valued based upon quoted market prices. The investments have a matching liability as the amounts are fully payable to the employees that earned the compensation. Changes in value of these securities and changes to the matching liability to employees are both recognized in earnings and, as a result, there is no impact to consolidated net income.

At June 30, 2019 and December 31, 2018, we held debt securities of $49.8 million and $40.1 million, respectively, in our captive insurance subsidiary. The types of securities included in the investment portfolio of our captive insurance subsidiary are typically U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from less than one year to ten years. These securities are classified as available-for-sale and are valued based upon quoted market prices or other observable inputs when quoted market prices are not available. The amortized cost of debt securities, which approximates fair value, held by our captive insurance subsidiary is adjusted for amortization of premiums and accretion of discounts to maturity. Changes in the values of these securities are recognized in accumulated other comprehensive income (loss) until the gain or loss is realized or until any unrealized loss is deemed to be other-than-temporary. We review any declines in value of these securities

for other-than-temporary impairment and consider the severity and duration of any decline in value. To the extent an other-than-temporary impairment is deemed to have occurred, an impairment is recorded and a new cost basis is established.

Our captive insurance subsidiary is required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to these securities may be limited.

Fair Value Measurements

Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. We have no investments for which fair value is measured on a recurring basis using Level 3 inputs.

The equity instruments with readily determinable fair values we held at June 30, 2019 and December 31, 2018 were primarily classified as having Level 1 and Level 2 fair value inputs. In addition, we had derivative instruments which were classified as having Level 2 inputs, which consist primarily of foreign currency forward contracts and interest rate swap agreements with a gross asset balance of $12.9 million and $10.9 million at June 30, 2019 and December 31, 2018, respectively, and a gross liability balance of $4.0 million and $6.2 million at June 30, 2019 and December 31, 2018, respectively.

Note 7 includes a discussion of the fair value of debt measured using Level 2 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of net operating results of the property, capitalization rates and discount rates.

The Operating Partnership

Our evaluation of the appropriateness of classifying the Operating Partnership’s common units of partnership interest, or units, held by Simon and the Operating Partnership's limited partners within permanent equity considered several significant factors. First, as a limited partnership, all decisions relating to the Operating Partnership’s operations and distributions are made by Simon, acting as the Operating Partnership’s sole general partner. The decisions of the general partner are made by Simon's Board of Directors or management. The Operating Partnership has no other governance structure. Secondly, the sole asset of Simon is its interest in the Operating Partnership. As a result, a share of common stock of Simon, or common stock, if owned by the Operating Partnership, is best characterized as being similar to a treasury share and thus not an asset of the Operating Partnership.

Limited partners of the Operating Partnership have the right under the Operating Partnership’s partnership agreement to exchange their units for shares of common stock or cash, as selected by Simon as the sole general partner. Accordingly, we classify units held by limited partners in permanent equity because Simon may elect to issue shares of common stock to limited partners exercising their exchange rights rather than using cash. Under the Operating Partnership’s partnership agreement, the Operating Partnership is required to redeem units held by Simon only when Simon has repurchased shares of common stock. We classify units held by Simon in permanent equity because the decision to redeem those units would be made by Simon.

Net income attributable to noncontrolling interests (which includes nonredeemable and redeemable noncontrolling interests in consolidated properties) is a component of consolidated net income.

A rollforward of noncontrolling interests is as follows:


	For the Three Months Ended				For the Six Months Ended

Derivative Financial Instruments

We record all derivatives on our consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have designated a derivative as a hedge and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We may use a variety of derivative financial instruments in the normal course of business to selectively manage or hedge a portion of the risks associated with our indebtedness and interest payments. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and caps. We require that hedging derivative instruments be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract.

As of June 30, 2019 and December 31, 2018, we had no outstanding interest rate derivatives. We generally do not apply hedge accounting to interest rate caps, which had a nominal value as of June 30, 2019 and December 31, 2018, respectively.

We are also exposed to fluctuations in foreign exchange rates on financial instruments which are denominated in foreign currencies, primarily in Yen and Euro. We use currency forward contracts, cross currency swap contracts and foreign currency denominated debt to manage our exposure to changes in foreign exchange rates on certain Yen and Euro-denominated receivables and net investments. Currency forward contracts involve fixing the Yen:USD or Euro:USD exchange rate for delivery of a specified amount of foreign currency on a specified date. The currency forward contracts are typically cash settled in U.S. dollars for their fair value at or close to their settlement date.

We had the following Euro:USD forward contracts designated as net investment hedges at June 30, 2019 and December 31, 2018 (in millions):


			Asset (Liability) Value as of
			June 30,		December 31,
Notional Value		Maturity Date	2019		2018
€	50.0	May 15, 2019		—		(0.8)
€	50.0	May 15, 2020		—		(1.5)
€	50.0	May 14, 2021		(0.3)		(2.0)

Asset balances in the above table are included in deferred costs and other assets. Liability balances in the above table are included in other liabilities.

We use a Euro-denominated cross-currency swap agreement to manage our exposure to changes in foreign exchange rates by swapping $150.0 million of 4.38% fixed rate U.S. dollar-denominated debt to 1.37% fixed rate Euro-denominated debt of €121.6 million. The cross-currency swap matures on December 1, 2020. The fair value of our cross-currency swap agreement at June 30, 2019 was $12.9 million and is included in deferred costs and other assets. We use a Yen-denominated cross-currency swap agreement designated as a net investment hedge to manage our exposure to changes in foreign exchange rates by swapping $200.1 million of 4.38% fixed rate U.S. dollar-denominated debt to ¥22.3 billion of 1.19% fixed rate Yen-denominated debt. The cross-currency swap matures on December 1, 2020. The fair value of our cross-currency swap agreement at June 30, 2019 was $3.7 million and is included in other liabilities.

We have designated the currency forward contracts and cross-currency swaps as net investment hedges. Accordingly, we report the changes in fair value in other comprehensive income (loss). Changes in the value of these forward contracts are offset by changes in the underlying hedged Euro or Yen-denominated joint venture investment.

The total gross accumulated other comprehensive income related to the Operating Partnership’s derivative activities, including our share of the other comprehensive income from unconsolidated entities, approximated $42.4 million and $37.9 million as of June 30, 2019 and December 31, 2018, respectively.

New Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, "Leases," codified as Accounting Standards Codification (ASC) 842, which results in lessees recognizing most leased assets and corresponding lease liabilities on the balance sheet. Lessor accounting remains substantially similar to the previous accounting; however, certain refinements were made to conform the standard with the recently issued revenue recognition guidance in ASU 2014-09, “Revenue From Contracts With Customers”, specifically related to the allocation and recognition of contract consideration earned from lease and non-lease revenue components. ASC 842 also limits the capitalization of leasing costs to initial direct costs, which, if applied in 2018, would have reduced our capitalized leasing costs and correspondingly increased expenses by approximately $45 million, of which $11.0 million and $22.3 million related to the three and six months ended June 30, 2018, respectively.

Substantially all of our revenues and the revenues of our equity method investments are earned from arrangements that are within the scope of ASC 842. On July 30, 2018, the FASB issued ASU 2018-11, also codified as ASC 842, which created a practical expedient that provides lessors an option not to separate lease and non-lease components when certain criteria are met and instead account for those components as a single lease component. We determined that our lease arrangements meet the criteria under the practical expedient to account for lease and non-lease components as a single lease component, which alleviates the requirement upon adoption of ASC 842 that we reallocate or separately present consideration from lease and non-lease components. On January 1, 2019, we began recognizing consideration received from fixed common area maintenance arrangements on a straight-line basis as this consideration is attributed to the lease component.

We, as a lessor, retain substantially all of the risks and benefits of ownership of the investment properties and continue to account for our leases as operating leases. We accrue fixed lease income on a straight-line basis over the terms of the leases. Substantially all of our retail tenants are also required to pay overage rents based on sales over a stated base amount during the lease year. We recognize this variable lease consideration only when each tenant’s sales exceed the applicable sales threshold. We amortize any tenant inducements as a reduction of revenue utilizing the straight-line method over the term of the related lease or occupancy term of the tenant, if shorter.

We structure our leases to allow us to recover a significant portion of our property operating, real estate taxes, repairs and maintenance, and advertising and promotion expenses from our tenants. A substantial portion of our leases, other than those for anchor stores, require the tenant to reimburse us for a substantial portion of our operating expenses, including common area maintenance, or CAM, real estate taxes and insurance. This significantly reduces our exposure to increases in costs and operating expenses resulting from inflation or otherwise. Such property operating expenses typically include utility, insurance, security, janitorial, landscaping, food court and other administrative expenses. For substantially all of our leases in the U.S. mall portfolio, we receive a fixed payment from the tenant for the CAM component which is recognized as revenue on a straight-line basis over the term of the lease. When not reimbursed by the fixed-CAM component, CAM expense reimbursements are based on the tenant’s proportionate share of the allocable operating expenses and CAM capital expenditures for the property. We accrue reimbursements from tenants for recoverable portions of all of these expenses as variable lease consideration in the period the applicable expenditures are incurred. We recognize differences between estimated recoveries and the final billed amounts in the subsequent year. These differences were not material in any period presented. Our advertising and promotional costs are expensed as incurred. Provisions for credit losses are recognized as a reduction of lease income. Refer to note 9 for further disclosure of lease income.

Minimum fixed lease consideration under non-cancelable tenant operating leases for each of the next five years and thereafter, excluding variable lease consideration, for the years ending December 31, as of June 30, 2019, is as follows:


2019	$	3,651,178
2020		3,392,090
2021		3,031,609
2022		2,638,397
2023		2,176,031
Thereafter		5,817,996
	$	20,707,301

Further, ASC 842 requires recognition on our consolidated balance sheets of leases of land and other arrangements where we are the lessee. Upon adoption on January 1, 2019, we recognized a right of use asset and corresponding lease liability of $524.0 million representing the present value of future lease payments required under our lessee arrangements. We utilized lease terms ranging from 2019 to 2090 including periods for which exercising an extension option is reasonably assured, and discount rates from 3.97% to 5.52% when determining the present value of future lease payments. All of our existing lessee arrangements upon adoption continue to be classified as operating leases and the pattern of lease expense recognition will be unchanged. Refer to note 10 for further disclosure regarding ground leases recognized as a result of the adoption of ASC 842.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses," which introduced new guidance for an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. Instruments in scope include loans, held-to-maturity debt securities, and net investments in leases as well as reinsurance and trade receivables. In November 2018, the FASB issued ASU 2018-19, which clarifies that operating lease receivables are outside the scope of the new standard. This standard will be effective for us in fiscal years beginning after December 15, 2019. We are currently evaluating the impact that the adoption of the new standard will have on our consolidated financial statements.

Real Estate Joint Ventures and Investments

Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties and diversify our risk in a particular property or portfolio of properties. As discussed in note 2, we held joint venture interests in 82 properties as of June 30, 2019.

Certain of our joint venture properties are subject to various rights of first refusal, buy-sell provisions, put and call rights, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and the industry. We and our partners in these joint ventures may initiate these provisions (subject to any applicable lock up or similar restrictions), which may result in either the sale of our interest or the use of available cash or borrowings, or the use of limited partnership interests in the Operating Partnership, to acquire the joint venture interest from our partner.

We may provide financing to joint ventures primarily in the form of interest bearing construction loans. As of June 30, 2019 and December 31, 2018, we had construction loans and other advances to related parties totaling $85.9 million and $85.8 million, respectively, which are included in deferred costs and other assets in the accompanying consolidated balance sheets.

Unconsolidated Entity Transactions

During the first quarter of 2019, we disposed of our interests in a multi-family residential investment. Our share of the gross proceeds was $17.3 million. The gain of $15.6 million is included in other income in the accompanying consolidated statement of operations and comprehensive income.

On September 25, 2018, as discussed in note 4, we acquired the remaining 50% interest in The Outlets at Orange from our joint venture partner. The Operating Partnership issued 475,183 units at a price of $176.99 to acquire this remaining interest. As a result of this acquisition, we now own 100% of this property.

As of June 30, 2019 and December 31, 2018, we had an 11.7% legal noncontrolling equity interest in HBS, a joint venture we formed with Hudson’s Bay Company. Our share of net (loss) income, net of amortization of our excess investment, was ($5.6) million and $3.7 million for the three months ended June 30, 2019 and 2018, respectively, and ($8.2) million and $7.6 million for the six months ended June 30, 2019 and 2018, respectively. Total revenues, operating income and consolidated net (loss) income of HBS were approximately $67.2 million, $1.1 million and ($22.1) million, respectively, for the six months ended June 30, 2019 and $174.2 million, $102.3 million and $53.8 million, respectively, for the six months ended June 30, 2018.

On June 7, 2018, Aventura Mall, a property in which we own a 33.3% interest, refinanced its $1.2 billion mortgage and its $200.8 million construction loan with a $1.75 billion mortgage at a fixed interest rate of 4.12% that matures on July 1, 2028. An early repayment charge of $30.9 million was incurred at the property, which along with the write-off of deferred debt issuance costs of $6.5 million, is included in interest expense in the accompanying combined joint venture statements of operations. Our $12.5 million share of the charge associated with the repayment is included in income from unconsolidated entities in the accompanying consolidated statements of operations and comprehensive income. Excess proceeds from the financing were distributed to the venture partners in June 2018.

In May 2017, Colorado Mills, a property in which we have a 37.5% interest, sustained significant hail damage. During the second quarter of 2017, the property recorded an impairment charge of approximately $32.5 million based on the net carrying value of the assets damaged, which was fully offset by anticipated insurance recoveries. As of June 30, 2018, the property had received business interruption proceeds and also property damage proceeds of $58.3 million, which resulted in the property recording a $25.8 million gain in 2018. Our share of the gain, $9.7 million, is reflected within the gain upon acquisition of controlling interests, sale or disposal of, or recovery on, assets and interests in unconsolidated entities and impairment, net in the accompanying consolidated statements of operations and comprehensive income.

On September 15, 2016, we and a group of co-investors acquired certain assets and liabilities of Aéropostale, a retailer of apparel and accessories, out of bankruptcy. The interests were acquired through two separate joint ventures, a licensing venture and an operating venture. In April 2018, we contributed our entire interest in the licensing venture in exchange for additional interests in ABG, a brand development, marketing, and entertainment company. As a result, we recognized a $35.6 million non-cash gain representing the increase in value of our previously held interest in the licensing venture, which is included in other income in the accompanying consolidated statements of operations and comprehensive income. At June 30, 2019, our noncontrolling equity method interests in the operations venture of Aéropostale and in ABG were 44.95% and 5.40%, respectively.

European Investments

At June 30, 2019, we owned 63,924,148 shares, or approximately 21.9%, of Klépierre, which had a quoted market price of $33.52 per share. Our share of net income, net of amortization of our excess investment, was $21.2 million and $24.8 million for the three months ended June 30, 2019 and 2018, respectively, and $39.0 million and $47.7 million for the six months ended June 30, 2019 and 2018, respectively. Based on applicable Euro:USD exchange rates and after our conversion of Klépierre’s results to GAAP, Klépierre’s total revenues, operating income and consolidated net income were approximately $760.2 million, $318.5 million and $276.6 million, respectively, for the six months ended June 30, 2019 and $814.7 million, $333.3 million and $364.4 million, respectively, for the six months ended June 30, 2018.

During the six months ended June 30, 2019 and 2018, Klépierre completed the disposal of its interests in certain shopping centers. In connection with these disposals, we recorded gains of $2.7 million and $13.4 million, respectively, representing our

share of the gains recognized by Klépierre, which is included in gain on sale or disposal of, or recovery on, assets and interests in unconsolidated entities and impairment, net in the accompanying consolidated statements of operations and comprehensive income.

We have an interest in a European investee that had interests in nine Designer Outlet properties as of June 30, 2019 and December 31, 2018, respectively. As of June 30, 2019, our legal percentage ownership interests in these properties ranged from 45% to 94%.

In addition, we have a 50.0% noncontrolling interest in a European property management and development company that provides services to the Designer Outlet properties.

We also have minority interests in Value Retail PLC and affiliated entities, which own or have interests in and operate nine luxury outlets located throughout Europe and we also have a direct minority ownership in three of those outlets. At June 30, 2019 and December 31, 2018, the carrying value of these equity instruments without readily determinable fair values was $140.8 million and is included in deferred costs and other assets.

Asian Joint Ventures

We conduct our international Premium Outlet operations in Japan through a joint venture with Mitsubishi Estate Co., Ltd. We have a 40% noncontrolling ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $200.9 million and $232.1 million as of June 30, 2019 and December 31, 2018, respectively, including all related components of accumulated other comprehensive income (loss). We conduct our international Premium Outlet operations in South Korea through a joint venture with Shinsegae International Co. We have a 50% noncontrolling ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $162.3 million and $166.3 million as of June 30, 2019 and December 31, 2018, respectively, including all related components of accumulated other comprehensive income (loss).

“Excess Investment” represents the unamortized difference of our investment over our share of the equity in the underlying net assets of the joint ventures or other investments acquired and has been determined to primarily relate to the fair value of the investment properties, intangible assets, and debt premiums and discounts. We amortize excess investment over the life of the related depreciable components of assets acquired, typically no greater than 40 years, the terms of the applicable leases, the estimated useful lives of the finite lived intangibles, and the applicable debt maturity, respectively. The amortization is included in the reported amount of income from unconsolidated entities.

Unsecured Debt

At June 30, 2019, our unsecured debt consisted of $15.0 billion of senior unsecured notes of the Operating Partnership, $125.0 million outstanding under the Operating Partnership’s $4.0 billion unsecured revolving credit facility, or Credit Facility, and $1.4 billion outstanding under the Operating Partnership’s global unsecured commercial paper note program, or Commercial Paper program.

On June 30, 2019, we had an aggregate available borrowing capacity of $5.9 billion under the Credit Facility and the Operating Partnership’s $3.5 billion unsecured revolving credit facility, or Supplemental Facility, and together with the Credit Facility, the Credit Facilities. The maximum aggregate outstanding balance under the Credit Facilities during the six months ended June 30, 2019 was $130.7 million and the weighted average outstanding balance was $125.2 million. Letters of credit of $11.3 million were outstanding under the Credit Facilities as of June 30, 2019.

The Credit Facility’s initial borrowing capacity of $4.0 billion may be increased to $5.0 billion during its term and provides for borrowings denominated in U.S. dollars, Euro, Yen, Sterling, Canadian dollars and Australian dollars. Borrowings in currencies other than the U.S. dollar are limited to 95% of the maximum revolving credit amount, as defined. The initial maturity date of the Credit Facility is June 30, 2021 and can be extended for an additional year to June 30, 2022 at our sole option, subject to our continued compliance with the terms thereof. The base interest rate on the Credit Facility is LIBOR plus 77.5 basis points with a facility fee of 10 basis points.

The Supplemental Facility’s initial borrowing capacity of $3.5 billion may be increased to $4.5 billion during its term and provides for borrowings denominated in U.S. dollars, Euro, Yen, Sterling, Canadian dollars and Australian dollars. The initial maturity date of the Supplemental Facility was extended to June 30, 2022 and can be extended for an additional year to June 30, 2023 at our sole option, subject to our continued compliance with the terms thereof. The base interest rate on the Supplemental Facility is LIBOR plus 77.5 basis points with a facility fee of 10 basis points.

The Operating Partnership also has available a Commercial Paper program of $2.0 billion, or the non-U.S. dollar equivalent thereof. The Operating Partnership may issue unsecured commercial paper notes, denominated in U.S. dollars, Euro and other currencies. Notes issued in non-U.S. currencies may be issued by one or more subsidiaries of the Operating Partnership and are guaranteed by the Operating Partnership. Notes will be sold under customary terms in the U.S. and Euro commercial paper note markets and rank (either by themselves or as a result of the guarantee described above) pari passu with the Operating Partnership’s other unsecured senior indebtedness. The Commercial Paper program is supported by the Credit Facilities and if necessary or appropriate, we may make one or more draws under either of the Credit Facilities to pay amounts outstanding from time to time on the Commercial Paper program. On June 30, 2019, we had $1.4 billion outstanding under the Commercial Paper program, fully comprised of U.S. dollar-denominated notes with a weighted average interest rate of 2.47%. These borrowings have a weighted average maturity date of September 19, 2019 and reduce amounts otherwise available under the Credit Facilities.

On February 1, 2019, the Operating Partnership repaid at maturity $600.0 million of senior unsecured notes with a fixed interest rate of 2.20%.

Mortgage Debt

Total mortgage indebtedness was $6.8 billion at June 30, 2019 and December 31, 2018.

Covenants

Our unsecured debt agreements contain financial covenants and other non-financial covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender, including adjustments to the applicable interest rate. As of June 30, 2019, we were in compliance with all covenants of our unsecured debt.

At June 30, 2019, our consolidated subsidiaries were the borrowers under 45 non-recourse mortgage notes secured by mortgages on 48 properties, including two separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of five properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt instruments contain financial and other non-financial covenants which are specific to the properties that serve as collateral for that debt. If the applicable borrower under these non-recourse mortgage notes were to fail to comply with these covenants, the lender could accelerate the debt and enforce its rights against their collateral. At June 30, 2019, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance could individually or in the aggregate, giving effect to applicable cross-default provisions, have a material adverse effect on our financial condition, liquidity or results of operations.

Fair Value of Debt

The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimate the fair values of consolidated fixed rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. We estimate the fair values of consolidated fixed rate unsecured notes using quoted market prices, or, if no quoted market prices are available, we use quoted market prices for securities with similar terms and maturities. The book value of our consolidated fixed rate mortgages and unsecured indebtedness including commercial paper was $22.4 billion as of June 30, 2019 and December 31, 2018. The fair values of these financial instruments and the related discount rate assumptions as of June 30, 2019 and December 31, 2018 are summarized as follows:


	June 30,			December 31,
	2019			2018

Litigation

We are involved from time-to-time in various legal and regulatory proceedings that arise in the ordinary course of our business, including, but not limited to, commercial disputes, environmental matters, and litigation in connection with transactions such as acquisitions and divestitures. We believe that current proceedings will not have a material adverse effect on our financial condition, liquidity, or results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated.

During the first quarter of 2019, we settled a lawsuit with our former insurance broker, Aon Risk Services Central Inc., related to the significant flood damage sustained at Opry Mills in May 2010. In accordance with a previous agreement with the prior co-investor in Opry Mills, a portion of the settlement was remitted to the co-investor. Our share of the settlement was approximately $68.0 million, which was recorded as other income in the accompanying consolidated statement of operations and comprehensive income.

Lease Commitments

As of June 30, 2019, a total of 23 of our consolidated properties are subject to ground leases. The termination dates of these ground leases range from 2019 to 2090, including periods for which exercising an extension option is reasonably assured. These ground leases generally require us to make fixed annual rental payments, or a fixed annual rental payment plus a percentage rent component based upon the revenues or total sales of the property. In addition, we have several regional office locations that are subject to leases with termination dates ranging from 2019 to 2028. These office leases generally require us to make fixed annual rental payments plus pay our share of common area, real estate, and utility expenses. Some of our ground and office leases include escalation clauses. All of our lease arrangements are classified as operating leases. We incurred ground lease expense and office lease expense, which are included in other expense and home office and regional expense, respectively, as follows:

Guarantees of Indebtedness

Joint venture debt is the liability of the joint venture and is typically secured by the joint venture property, which is non-recourse to us. As of June 30, 2019 and December 31, 2018, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $216.1 million (of which we have a right of recovery from our venture partners of $10.8 million). Mortgages guaranteed by the Operating Partnership are secured by the property of the joint venture which could be sold in order to satisfy the outstanding obligation and which has an estimated fair value in excess of the guaranteed amount.

Concentration of Credit Risk

Our U.S. Malls, Premium Outlets, and The Mills rely upon anchor tenants to attract customers; however, anchors do not contribute materially to our financial results as many anchors own their spaces. All material operations are within the United States and no customer or tenant accounts for 5% or more of our consolidated revenues.

Hurricane Impacts

During the third quarter of 2017, our two wholly-owned properties located in Puerto Rico sustained significant damage as a result of Hurricane Maria. Since the date of the loss, we have received $68.3 million of insurance proceeds from third-party carriers related to the two properties located in Puerto Rico, of which $42.7 million was used for property restoration and remediation and to reduce the insurance recovery receivable. During the three and six months ended June 30, 2019, we recorded $3.2 million and $7.6 million, respectively, as business interruption proceeds in other income in the accompanying consolidated statements of operations and comprehensive income.

2. Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of all controlled subsidiaries, and all significant intercompany amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim periods ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year.

These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for a fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes contained in the combined 2018 Annual Report on Form 10-K of Simon and the Operating Partnership. Certain reclassifications considered necessary for a fair presentation have been made to the prior period financial statements in order to conform to the current year presentation. These reclassifications have not changed the results of operations.

As of June 30, 2019, we consolidated 135 wholly-owned properties and 18 additional properties that are less than wholly-owned, but which we control or for which we are the primary beneficiary. We account for the remaining 82 properties, or the joint venture properties, as well as our investments in Klépierre, Aéropostale, Authentic Brands Group, LLC, or ABG, and HBS Global Properties, or HBS, using the equity method of accounting, as we have determined we have significant influence over their operations. We manage the day-to-day operations of 57 of the 82 joint venture properties, but have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties. Our investments in joint ventures in Japan, South Korea, Mexico, Malaysia, Germany, Canada, and the United Kingdom comprise 21 of the remaining 25 properties. These international properties are managed by joint ventures in which we share control.

Preferred distributions of the Operating Partnership are accrued at declaration and represent distributions on outstanding preferred units of partnership interests, or preferred units, and are included in net income attributable to noncontrolling interests. We allocate net operating results of the Operating Partnership after preferred distributions to limited partners and to Simon based on the partners’ respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributable to limited partners are reflected in net income attributable to noncontrolling interests. Simon’s weighted average ownership interest in the Operating Partnership was 86.8% and 86.9% for the six months ended June 30, 2019

and 2018, respectively. As of June 30, 2019 and December 31, 2018, Simon’s ownership interest in the Operating Partnership was 86.8%. We adjust the noncontrolling limited partners’ interests at the end of each period to reflect their interest in the net assets of the Operating Partnership.

Preferred unit requirements in the Operating Partnership’s accompanying consolidated statements of operations and comprehensive income represent distributions on outstanding preferred units and are recorded when declared.

4. Real Estate Acquisitions and Dispositions

Unless otherwise noted, gains and losses on property transactions are included in gain on sale or disposal of, or recovery on, assets and interests in unconsolidated entities and impairment, net in the accompanying consolidated statements of operations and comprehensive income. We capitalize asset acquisition costs and expense costs related to business combinations, as well as disposition related costs as they are incurred. We incurred a minimal amount of transaction expenses during the three and six months ended June 30, 2019 and 2018.

On September 25, 2018, we acquired the remaining 50% interest in The Outlets at Orange from our joint venture partner. The Operating Partnership issued 475,183 units, or approximately $84.1 million, as consideration for the acquisition. The property is subject to a $215.0 million, 4.22% fixed rate mortgage. We accounted for this transaction as an asset acquisition and substantially all of our investment has been determined to relate to investment property.

During the first six months of 2018, we recorded net gains of $144.9 million primarily related to our disposition activity which included the foreclosure of a consolidated property in satisfaction of its $200 million non-recourse mortgage.

Per Share and Per Unit Data

Per Share and Per Unit Data

5. Per Share and Per Unit Data

We determine basic earnings per share and basic earnings per unit based on the weighted average number of shares of common stock or units, as applicable, outstanding during the period and we consider any participating securities for purposes of applying the two-class method. We determine diluted earnings per share and diluted earnings per unit based on the weighted average number of shares of common stock or units, as applicable, outstanding combined with the incremental weighted average number of shares or units, as applicable, that would have been outstanding assuming all potentially dilutive securities were converted into shares of common stock or units, as applicable, at the earliest date possible. The following tables set forth the components of basic and diluted earnings per share and basic and diluted earnings per unit.

Net Income attributable to Common Stockholders — Basic and Diluted	$	495,324	$	547,004	$	1,043,799	$	1,167,658
Weighted Average Shares Outstanding — Basic and Diluted		308,708,798		309,355,154		308,842,682		309,966,005

For the three and six months ended June 30, 2019, potentially dilutive securities include units that are exchangeable for common stock and long-term incentive performance units, or LTIP units, granted under our long-term incentive performance programs that are convertible into units and exchangeable for common stock. No securities had a material dilutive effect for the three or six months ended June 30, 2019 and 2018. We have not adjusted net income attributable to common stockholders and weighted average shares outstanding for income allocable to limited partners or units, respectively, as doing so would have no dilutive impact. We accrue dividends when they are declared.
