Acquisition of Isle of Capri Casinos, Inc. and Refinancing

On May 1, 2017 (the “Isle Acquisition Date”), the Company completed its acquisition of Isle of Capri Casinos, Inc. pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) dated as of September 19, 2016 with Isle of Capri Casinos, Inc., a Delaware corporation (“Isle” or “Isle of Capri”), Eagle I Acquisition Corp., a Delaware corporation and a direct wholly-owned subsidiary of the Company, and Eagle II Acquisition Company LLC, a Delaware limited liability company and a direct wholly-owned subsidiary of the Company (the “Isle Acquisition” or the “Isle Merger”). As a result of the Isle Merger, Isle became a wholly-owned subsidiary of ERI and, at the effective time of the Isle Merger, each outstanding share of Isle’s stock converted into the right to receive $23.00 in cash or 1.638 shares of ERI common stock (the “Stock Consideration”), at the election of the applicable Isle shareholder and subject to proration such that the outstanding shares of Isle common stock were exchanged for aggregate consideration comprised of 58% cash, or $552.0 million, and 42% ERI common stock, or 28.5 million newly issued shares of ERI common stock. The total purchase consideration was $1.93 billion (See Note 3).

In connection with the Isle Acquisition, the Company completed a debt financing transaction comprised of: (a) a senior secured credit facility in an aggregate principal amount of $1.75 billion with a (i) term loan facility of $1.45 billion and (ii) revolving credit facility of $300.0 million and (b) $375.0 million of senior unsecured notes. The proceeds of such borrowings were used to pay the cash portion of the consideration payable in the Isle Merger, refinance all of Isle’s existing credit facilities, redeem or otherwise repurchase all of Isle’s senior and senior subordinated notes, refinance the Company’s existing credit facility and pay transaction fees and expenses related to the foregoing (See Note 9 for further discussion of the refinancing transaction and terms of such indebtedness).

On September 13, 2017, the Company issued an additional $500.0 million in aggregate principal amount of its 6% Senior Notes (as defined below) at an issue price equal to 105.5% of the principal amount. The 6% Senior Notes were issued as additional notes under the New Indenture dated March 29, 2017 (as defined below), as supplemented by the supplemental indenture dated as of May 1, 2017 between the Company, the guarantors party thereto and U.S. Bank National Association, pursuant to which the Company previously issued $375.0 million aggregate principal amount of 6% Senior Notes. The additional 6% Senior Notes formed part of a single class of securities together with the initial 6% Senior Notes for all purposes under the New Indenture, including waivers, amendments, redemptions and offers to purchase.

Transaction expenses attributed to the Isle Acquisition are reported on the accompanying statements of income related to legal, accounting, financial advisory services, severance, stock awards and other costs totaling $92.8 million and $8.6 million during the years ended December 31, 2017 and 2016, respectively. As of December 31, 2017, $0.1 million of accrued costs and expenses related to the Isle Acquisition are included in accrued other liabilities. Additionally, we recognized a loss of $27.3 million for the year ended December 31, 2017 related to the extinguishment of Isle debt and the payment of interest and call premiums in conjunction with the Isle Acquisition.

On August 22, 2016, Isle entered into a definitive agreement (the “Agreement”) to sell its casino and hotel property in Lake Charles, Louisiana, for $134.5 million, subject to a customary purchase price adjustment, to an affiliate of Laguna Development Corporation (the “Buyer”), a Pueblo of Laguna-owned business based in Albuquerque, New Mexico. The Agreement was assumed by the Company at the Isle Acquisition Date. On November 21, 2017, the Company terminated the Agreement. The closing of the transaction was subject to certain closing conditions, including obtaining certain gaming approvals, and was to occur on or before the termination date, which had been extended by the parties to November 20, 2017. The Buyer did not obtain the required gaming approvals prior to the termination date, and pursuant to the terms of the Agreement, the Company retained the Buyer’s $20.0 million deposit. The Buyer agreed to the termination and its terms. The $20.0 million forfeited deposit was recorded as income on the accompanying statements of income as “Proceeds from Terminated Sale.” In previous periods, the operations of Lake Charles have been classified as discontinued operations and as assets held for sale for all periods presented. As a result of the termination, Lake Charles is no longer classified as assets held for sale and accounted for as discontinued operations and is included in our results of operations for the eight-month period from the Isle Acquisition Date through December 31, 2017.

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation. The accompanying consolidated financial statements include the accounts of the Company as described in Note 1. All significant intercompany transactions have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates incorporated into the Company’s consolidated financial statements include estimated useful lives for depreciable and amortizable assets, estimated allowance for doubtful accounts receivable, estimated cash flows in assessing goodwill and indefinite-lived intangible assets for impairment and the recoverability of long‑lived assets, self‑insurance reserves, players’ club liabilities, contingencies and litigation, claims and assessments, and fair value measurements related to the Company’s long‑term debt. Actual results could differ from these estimates.

Cash and Cash Equivalents. Cash equivalents include investments in money market funds. Investments in this category can be redeemed immediately at the current net asset value per share. A money market fund is a mutual fund whose investments are primarily in short‑term debt securities designed to maximize current income with liquidity and capital preservation, usually maintaining per share net asset value at a constant amount, such as one dollar. Cash and cash equivalents also includes cash maintained for gaming operations. The carrying amounts approximate the fair value because of the short maturity of those instruments (Level 1).

Restricted Cash and Investments. Restricted cash includes cash reserved for unredeemed winning tickets from the Company’s racing operations, funds related to horsemen’s fines and certain simulcasting funds that are restricted to payments for improving horsemen’s facilities and racing purses, cash deposits that serve as collateral for letters of credit, surety bonds and short-term certificates of deposit that serve as collateral for certain bonding requirements. The estimated fair values of our restricted cash and investments are based upon quoted prices available in active markets (Level 1), or quoted prices for similar assets in active and inactive markets (Level 2), and represent the amounts we would expect to receive if we sold our restricted cash and investments. Restricted investments, included in Other Assets, net, relate to trading securities pledged as collateral by our captive insurance wholly-owned subsidiary.

The Company also has certificates of deposit which are used for security with the Nevada Department of Insurance for its self‑insured workers compensation, West Virginia Division of Environmental Protection and Port Resources for the land lease at Lake Charles. The Nevada certificate of deposit of $628,000 matured on January 28, 2018 at which time it was renewed and the maturity date was extended to January 29, 2019. The West Virginia certificates of deposits in the amounts of $123,000 and $76,000 both mature on October 27, 2018 and the Lake Charles certificate of deposit is for $1.0 million and matures on July 13, 2018.

Marketable Securities. Marketable securities consist primarily of trading securities held by the Company’s captive insurance subsidiary. The trading securities are primarily debt and equity securities that are purchased with the intention to resell in the near term. The trading securities are carried at fair value with changes in fair value recognized in current period income, and this accounting policy was implemented as of the Isle Acquisition Date. For the year ended December 31, 2017, we recorded a $0.1 million loss related to the change in fair value which is included in corporate expenses in the accompanying statements of income.

Accounts Receivable and Credit Risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of casino accounts receivable. The Company issues markers to approved casino customers following background checks and assessments of creditworthiness. Trade receivables, including casino and hotel receivables, are typically non‑interest bearing. Accounts are written off when management deems the account to be uncollectible. Recoveries of accounts previously written off are recorded when received. An estimated allowance for doubtful accounts is maintained to reduce the Company’s receivables to their carrying amount, which approximates fair value. The allowance is estimated based on specific review of customer accounts as well as historical collection experience and current economic and business conditions. Management believes that as of December 31, 2017 and 2016, no significant concentrations of credit risk related to receivables existed.

Inventories. Inventories are stated at the lower of average cost, using a first‑in, first‑out basis, or market. Inventories consist primarily of food and beverage, retail merchandise and operating supplies.

Property and Equipment. Property and equipment are stated at cost. Depreciation is computed using the straight‑line method over the estimated useful life of the asset or the term of the capitalized lease, whichever is less. Costs of major improvements are capitalized, while costs of normal repairs and maintenance are charged to expense as incurred. Gains or losses on the disposal of property and equipment are included in operating income.


Buildings and improvements		10 to 40 years
Land improvements		10 to 20 years
Furniture, fixtures and equipment		3 to 20 years
Riverboat		10 to 25 years

Investment in Unconsolidated Affiliates. The Company’s investments in unconsolidated affiliates which are 50% or less owned are accounted for under the equity method and included in other assets, net. The Company does have variable interests in variable interest entities; however, we are not the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.

The Company considers whether the fair values of any of its equity method investments have declined below their carrying value whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. Estimated fair value is determined using a discounted cash flow analysis based on estimated future results of the investee and market indicators of terminal year capitalization rate. There were no impairments of the Company’s equity method investments during 2017, 2016 or 2015.

Goodwill and Other Intangible Assets and Non‑Operating Real Properties. Goodwill represents the excess of purchase price over fair market value of net assets acquired in business combinations. Goodwill and indefinite-lived intangible assets must be reviewed for impairment at least annually and between annual test dates in certain circumstances. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. As a result of the annual impairment review for goodwill and indefinite-lived intangible assets, the Company recorded impairment charges of $34.9 million and $3.1 million related to goodwill and trade names, respectively, in 2017. No impairments were indicated as a result of the annual impairment review for goodwill and indefinite-lived intangible assets in 2016 or 2015.

We have designated certain assets, consisting principally of land and undeveloped properties, as non‑operating real property and have declared our intent to sell those assets. However, we do not anticipate that we will be able to sell the majority of the assets within the next twelve months. As such, these properties are not classified as held‑for‑sale as of December 31, 2017.

Indefinite‑Lived Intangible Assets. Indefinite‑lived intangible assets consist primarily of expenditures associated with obtaining racing and gaming licenses. Indefinite‑lived intangible assets are not subject to amortization, but are subject to an annual impairment test. If the carrying amount of an indefinite‑lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess amount.

Self‑Insurance Reserves. The Company is self‑insured for various levels of general liability, employee medical insurance coverage and workers’ compensation coverage. Insurance claims and reserves include accruals of estimated settlements for known claims, as well as accruals of estimates for claims incurred but not yet reported. We utilize independent consultants to assist management in its determination of estimated insurance liabilities. While the total cost of claims incurred depends on future developments, in managements’ opinion, recorded reserves are adequate to cover future claims payments. Self-insurance reserves for employee medical claims and workers’ compensations are included in accrued payroll and related on the consolidated balance sheets. Self-insurance reserves for general liability claims are included in accrued other liabilities on the consolidated balance sheets.

Outstanding Chip Liability. The Company recognizes the impact on gaming revenues on an annual basis to reflect an estimate of the change in the value of outstanding chips that are not expected to be redeemed. This estimate is determined by measuring the difference between the total value of chips placed in service less the value of chips in the inventory of chips under our control. This measurement is performed on an annual basis utilizing a methodology in which a consistent formula is applied to estimate the percentage value of chips not in custody that are not expected to be redeemed. In addition to the formula, certain judgments are made with regard to various denominations and souvenir chips. The outstanding chip liability is included in accrued other liabilities on the consolidated balance sheets.

Loyalty Program. The Company offers programs at its properties whereby our participating patrons can accumulate points for wagering that can be redeemed for credits for free play on slot machines, lodging, food and beverage, merchandise and in limited situations, cash. Based upon the estimated redemptions of frequent player program points, an estimated liability is established for the cost of redemption of earned but unredeemed points. The estimated cost of redemption utilizes estimates and assumptions of the mix of the various product offerings for which the points will be redeemed and costs of such product offerings. Changes in the programs, membership levels and changes in the redemption patterns of our participating patrons can impact this liability. The loyalty program liability is included in accrued other liabilities on the consolidated balance sheets.

Revenues and Promotional Allowances. The Company recognizes as casino revenue the net win from gaming activities, which is the difference between gaming wins and losses. Progressive jackpots are accrued and charged to revenue at the time the obligation to pay the jackpot is established. Gaming revenues are recognized net of certain cash and free play incentives. Pari‑mutuel commissions consist of commissions earned from thoroughbred and harness racing and importing of simulcast signals from other race tracks and are recognized at the time wagers are made. Such commissions are a designated portion of the wagering handle as determined by state racing commissions, and are shown net of the taxes assessed by state and local agencies, as well as purses and other contractual amounts paid to horsemen associations. The Company recognizes revenues from fees earned through the exporting of simulcast signals to other race tracks at the time wagers are made. Such fees are based upon a predetermined percentage of handle as contracted with the other race tracks. Hotel, food and beverage, and other operating revenues are recognized as services are performed. Advance deposits on rooms and advance ticket sales are recorded as accrued liabilities until services are provided to the customer.

The retail value of food, beverage, rooms and other services furnished to customers on a complimentary basis is included in gross revenues and then deducted as promotional allowances. The Company rewards customers, through the use of our loyalty programs, with complimentaries based on amounts wagered or won that can be redeemed for a specified time period. The Company also offers discretionary coupons to our customers, the retail values of which are included as a component of promotional allowances in the accompanying consolidated statements of income in accordance with FASB Section 605‑50 for revenue recognition.

The retail value of complimentaries included in promotional allowances is as follows (in thousands):

	For the Year Ended December 31,
	2017		2016		2015
Food and beverage	$	87,677	$	56,335	$	44,998
Hotel		37,117		27,070		15,711
Other		8,291		6,895		4,048
	$	133,085	$	90,300	$	64,757

The costs of providing such complimentary services are recorded in casino expenses in the accompanying consolidated statements of income and are estimated as follows (in thousands):

	For the Year Ended December 31,
	2017		2016		2015
Food and beverage	$	73,823	$	39,288	$	31,220
Hotel		15,795		10,077		6,638
Other		6,295		4,672		2,330
	$	95,913	$	54,037	$	40,188

Advertising. Advertising costs are expensed in the period the advertising initially takes place and are included in marketing and promotions expenses. Advertising costs included in marketing and promotion expenses were $33.0 million, $15.5 million and $11.0 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Income Taxes. We account for income taxes in accordance with ASC Topic 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred income tax liabilities and deferred income tax assets for the difference between the book basis and tax basis of assets and liabilities. We have recorded valuation allowances related to net operating loss carry forwards and certain temporary differences. Recognizable future tax benefits are subject to a valuation allowance, unless such tax benefits are determined to be more-likely-than-not realizable. We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Stock‑Based Compensation. We account for stock‑based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation. ASC 718 requires all share‑based payments to employees and non‑employee members of the Board of Directors, including grants of stock options and restricted stock units (“RSUs”), to be recognized in the consolidated statements of income based on their fair values and that compensation expense be recognized for awards over the requisite service period of the award or until an employee’s eligible retirement date, if earlier.

Earnings per Share. Basic earnings per share is computed by dividing net income (loss) by the weighted average shares outstanding during the reporting period. Diluted earnings per share is computed similarly to basic earnings per share except that the weighted average shares outstanding are increased to include additional shares from the assumed exercise of stock options and the assumed vesting of restricted share units, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options were exercised, that outstanding restricted share units were released and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period.

Reclassifications

Certain reclassifications of prior period presentations have been made to conform to the current period presentation.

Recently Issued Accounting Pronouncements – New Developments

In May 2014 (amended January 2017), the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” (Topic 606) which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and eliminates existing industry guidance, including revenue recognition guidance specific to the gaming industry. The FASB has also recently issued several amendments to the standard, including narrow-scope improvements and practical expedients (ASU 2016-12) and clarification on accounting for and identifying performance obligations (ASU 2016-10). The core principle of the revenue model indicates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The guidance is effective for interim and annual periods beginning after December 15, 2017. While early adoption is permitted for interim and annual periods beginning after December 15, 2016, we adopted this standard effective January 1, 2018, and elected to apply the full retrospective adoption method.

The adoption of the new standard on January 1, 2018, principally affects the presentation of promotional allowances and how the Company measures the liability associated with our customer loyalty programs. The current presentation of gross revenues for complimentary goods and services provided to guests with a corresponding offsetting amount included in promotional allowances will be eliminated. This adjustment in presentation of promotional allowances will not have an impact on the Company’s historically reported net operating revenues.

Liabilities associated with our customer loyalty programs are no longer valued at cost; rather a deferred revenue model is used to account for the classification and timing of revenue to be recognized related to the redemption of loyalty program liabilities by the customer. Points earned under the Company’s loyalty programs are deemed to be separate performance obligations, and recorded as a reduction of casino revenues when earned at the retail value of such benefits owed to the customer and recognized as departmental revenue based on where such points are redeemed, upon fulfillment of the performance obligation. Upon adoption, the Company’s change in liability associated with the customer loyalty programs will not be significant. Accordingly, we expect the cumulative effect adjustment to our retained earnings upon adoption will not be significant.

Subsequent to the adoption of Topic 606, food and beverage, lodging and other services furnished to our guests on a complimentary basis will be measured at the respective estimated standalone selling prices and included as revenues within food and beverage, lodging, and retail, entertainment and other, which will result in a corresponding decrease in gaming revenues. The costs of providing such complimentary goods and services will be included as expenses within food and beverage, lodging, and retail, entertainment and other, which will result in a decrease in casino expenses.

Additionally, as a result of the adoption of the new standard, certain adjustments and other reclassifications to and between revenue categories and to and between expense categories were required; however, the amounts associated with such adjustments will not have a significant impact on the Company’s previously reported operating income or net income.

In January 2017, the FASB issued Accounting Standards Update ASU No. 2017-04, “Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment.” This amended guidance is intended to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of goodwill. Under the amended guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The elimination of Step 2 from the goodwill impairment test should reduce the cost and complexity of evaluating goodwill for impairment. Amendments should be applied on a prospective basis disclosing the nature of and reason for the change in accounting principle upon transition. Disclosure should be provided in the first annual period and in the interim period in which the entity initially adopts the amendments. Updated amendments are effective for the interim and annual periods beginning after December 15, 2019, and early adoption is permitted. We adopted this guidance effective October 1, 2017, and, in conjunction with the Company’s annual impairment assessment, recorded a $34.9 million goodwill impairment charge in 2017.

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations – Clarifying the Definition of a Business.” This amendment is intended to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisition (or disposals) of assets or businesses. Amendments in this update provide a more robust framework to use in determining when a set of assets and activities is a business and to provide more consistency in applying the guidance, reduce the costs of application, and make the definition of a business more operable. The amendments are effective for interim and annual periods beginning after December 15, 2017. Early adoption is allowed as follows: (1) transactions for which acquisition date occurs before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance and (2) transactions in which a subsidiary is deconsolidated or a group of assets is derecognized that occur before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. We currently anticipate adopting this accounting standard during the first quarter of 2018, and the adoption will result in future acquisitions which do not involve substantive processes being accounted for as asset acquisitions.

In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows – Restricted Cash.” This guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash and cash equivalents. The amendments in this update are effective for the interim and annual periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We adopted this standard effective January 1, 2018, which will impact the presentation of the Statement of Cash Flows as well as require additional footnote disclosure to reconcile the balance sheet to the revised cash flow presentation.

In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” This new guidance is intended to reduce diversity in practice in how certain cash receipts and payments are classified in the statement of cash flows, including debt prepayment or extinguishment costs, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, and distributions from certain equity method investees. The guidance is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. The guidance requires application using a retrospective transition method. We adopted this standard effective January 1, 2018, which should not have a significant impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Accounting for Credit Losses,” which amends the guidance on the impairment of financial instruments. This update adds an impairment model (known as the current expected credit losses model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes, as an allowance, its estimate of expected credit losses. The effective date for this update is for the annual and interim periods beginning after December 15, 2019 and early adoption is permitted beginning after December 15, 2018. We are currently evaluating the impact of adopting this guidance on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02 “Leases” which addresses the recognition and measurement of leases. Under the new guidance, for all leases (with the exception of short-term leases), at the commencement date, lessees will be required to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Further, the new lease guidance simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and liabilities, which no longer provides a source for off balance sheet financing. The effective date for this update is for the annual and interim periods beginning after December 15, 2018 with early adoption permitted. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements.

Currently, we do not have any material capital leases or any material operating leases where we are the lessor. Our operating leases, primarily relating to certain ground leases and slot machines or VLTs, will be recorded on the balance sheet as an ROU asset with a corresponding lease liability, which will be amortized using the effective interest rate method as payments are made. The ROU asset will be depreciated on a straight-line basis and recognized as lease expense. The qualitative and quantitative effects of adoption of ASU 2016-02 are still being analyzed, and we are in the process of evaluating the full effect the new guidance will have on our consolidated financial statements including any new considerations with respect to the Isle Acquisition.

Isle Acquisition and Reno Acquisition and Preliminary Purchase Accounting

Note 3. Isle Acquisition and Reno Acquisition and Preliminary Purchase Accounting

Preliminary Purchase Price Accounting – Isle of Capri

On May 1, 2017, the Company completed its acquisition of Isle. The purchase consideration and allocation are still considered preliminary pending management’s final assessment of fair values. The total purchase consideration in the Isle Acquisition was determined with reference to the fair value on the date of the Merger Agreement as follows:

Purchase consideration calculation (dollars in thousands, except shares and stock price)	Shares		Per share
Cash paid for outstanding Isle common stock (1)					$	552,050
Shares of ERI common stock issued for Isle common stock (2)		28,468,182	$	19.12		544,312
Cash paid by ERI to retire Isle's long-term debt (3)						828,000
Shares of ERI common stock for Isle equity awards (4)						10,383
Purchase consideration					$	1,934,745

(1)

The cash component of the consideration represents 58% of the aggregate consideration paid in the Isle Acquisition. The Merger Agreement provided that Isle stockholders could elect to exchange each share of Isle common stock for either $23.00 in cash or 1.638 shares of ERI common stock, subject to proration such that the outstanding shares of Isle common stock will be exchanged for aggregate consideration comprised of 58% cash and 42% ERI common stock. See discussion of Stock Consideration component in note (2) below.

(2)

The Stock Consideration component of the consideration represents 42% of the aggregate consideration paid in the Isle Acquisition. The Merger Agreement provided that 58% of the aggregate consideration would be paid by ERI in cash, as described in note (1) above. The remaining 42% of the aggregate consideration was paid in shares of ERI common stock. The total Stock Consideration and per share consideration above were based on the ERI stock price on April 28, 2017 (the last business day prior to Isle Acquisition Date) which was $19.12 per share.

(3)	In addition to the cash paid to retire the principal amounts outstanding of Isle’s long-term debt, ERI paid $26.6 million in premiums and interest.

(4)

This amount represents consideration paid for the replacement of Isle’s outstanding equity awards. As discussed in Note 1, Isle’s outstanding equity awards were replaced by ERI equity awards with similar terms. A portion of the fair value of ERI awards issued represents consideration transferred, while a portion represents compensation expense based on the vesting terms of the equity awards.

The following table summarizes the preliminary purchase accounting of the purchase consideration to the identifiable assets acquired and liabilities assumed in the Isle Acquisition as of the Isle Acquisition Date, with the excess recorded as goodwill. The fair values were based on management’s analysis, including preliminary work performed by third-party valuation specialists. The following table summarizes our preliminary purchase price accounting of the acquired assets and liabilities as of December 31, 2017 (dollars in thousands):

Current and other assets, net	$	135,925
Property and equipment		908,816
Goodwill		715,196
Intangible assets (i)		517,470
Other noncurrent assets		15,082
Total assets		2,292,489
Current liabilities		(144,306	)
Deferred income taxes (ii)		(186,772	)
Other noncurrent liabilities		(26,666	)
Total liabilities		(357,744	)
Net assets acquired	$	1,934,745

(i)	Intangible assets consist of gaming licenses, trade names, and player relationships.

(ii)	Deferred tax liabilities were derived based on fair value adjustments for property and equipment and identified intangibles.

During the three months ended December 31, 2017, the Company adjusted the Isle of Capri preliminary purchase price accounting, as disclosed in the June 30, 2017 and September 30, 2017 Form 10-Q filings, to their updated values. Except for the reclassification of the Lake Charles assets and liabilities, which were previously classified as assets held for sale as of the Isle Acquisition Date and reversed as a result of the sale termination, the updated purchase price accounting resulted in minimal changes and refinements by management.

Valuation methodologies under both a market and income approach used for the identifiable net assets acquired in the Isle Acquisition make use of Level 1 and Level 3 inputs including quoted prices in active markets and discounted cash flows using current interest rates and are provisional pending development of a final valuation.

Trade receivables and payables, inventory and other current and noncurrent assets and liabilities were valued at the existing carrying values as they represented the estimated fair value of those items at the Isle Acquisition Date, based on management’s judgement and estimates.

The fair value of land was determined using the market approach, which arrives at an indication of value by comparing the site being valued to sites that have been recently acquired in arm’s-length transactions. The market data is then adjusted for any significant differences, to the extent known, between the identified comparable sites and the site being valued. Building and site improvements were valued using the cost approach using a direct cost model built on estimates of replacement cost. With respect to personal property components of the assets, personal property assets with an active and identifiable secondary market such as riverboats, gaming equipment, computer equipment and vehicles were valued using the market approach. Other personal property assets such as furniture, fixtures, computer software, and restaurant equipment were valued using the cost approach which is based on replacement or reproduction costs of the asset.

The cost approach is an estimation of fair value developed by computing the current cost of replacing a property and subtracting any depreciation resulting from one or more of the following factors: physical deterioration, functional obsolescence, and/or economic obsolescence. The income approach incorporates all tangible and intangible property and served as a ceiling for the fair values of the acquired assets of the ongoing business enterprise, while still taking into account the premise of highest and best use. In the instance where the business enterprise value developed via the income approach was exceeded by the initial fair values of the underlying assets, an adjustment to reflect economic obsolescence was made to the tangible assets on a pro rata basis to reflect the contributory value of each individual asset to the enterprise as a whole.

The fair value of the gaming licenses was determined using the excess earnings or replacement cost methodology based on the respective states’ legislation. The excess earnings methodology, which is an income approach methodology that allocates the projected cash flows of the business to the gaming license intangible assets less charges for the use of other identifiable assets of Isle including working capital, fixed assets and other intangible assets. This methodology was considered appropriate as the gaming licenses are the primary asset of Isle and the licenses are linked to each respective facility. Under the respective state’s gaming legislation, the property specific licenses can only be acquired if a theoretical buyer were to acquire each existing facility. The existing licenses could not be acquired and used for a different facility. The properties’ estimated future cash flows were the primary assumption in the respective valuations. Cash flow estimates included net gaming revenue, gaming operating expenses, general and administrative expenses, and tax expense. The replacement cost methodology is a cost approach methodology based on replacement or reproduction cost of the gaming license as an indicator of fair value.

Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, ERI would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, ERI avoids any such payments and record the related intangible value of ERI’s ownership of the brand name. The primary assumptions in the valuation included revenue, pre-tax royalty rate, and tax expense.

ERI has assigned an indefinite useful life to the gaming licenses, in accordance with its review of the applicable guidance of ASC Topic 350, “Intangibles-Goodwill and Other” (“ASC 350”). The standard required ERI to consider, among other things, the expected use of the asset, the expected useful life of other related asset or asset group, any legal, regulatory, or contractual provisions that may limit the useful life, ERI’s own historical experience in renewing similar arrangements, the effects of obsolescence, demand and other economic factors, and the maintenance expenditures required to obtain the expected cash flows. In that analysis, ERI determined that no legal, regulatory, contractual, competitive, economic or other factors limit the useful lives of these intangible assets. The acquired Isle properties currently have licenses in Louisiana, Pennsylvania, Iowa, Missouri, Mississippi, Florida and Colorado. The renewal of each state’s gaming license depends on a number of factors, including payment of certain fees and taxes, providing certain information to the state’s gaming regulator, and meeting certain inspection requirements. However, ERI’s historical experience has not indicated, nor does ERI expect, any limitations regarding its ability to continue to renew each license. No other competitive, contractual, or economic factor limits the useful lives of these assets. Accordingly, ERI has preliminarily concluded that the useful lives of these licenses are indefinite.

For the period from the Isle Acquisition Date through December 31, 2017, Isle and its subsidiaries generated net revenue of $599.6 million and net income of $102.6 million.

Final Purchase Price Accounting – Silver Legacy and Circus Reno

On November 24, 2015, the Company acquired all of the assets and properties of Circus Reno and the 50% membership interest in the Silver Legacy Joint Venture owned by Galleon, Inc. The total purchase consideration was $223.6 million as presented in the following table.

Purchase consideration calculation (dollars in thousands)	Silver Legacy			Circus Reno		Total
Cash consideration paid by ERI for MGM’s 50% equity interest and MGM’s member note	$	56,500		$	16,000	$	72,500
Fair value of ERI’s pre-existing 50% equity interest		56,500			—		56,500
Settlement of Silver Legacy’s long-term debt (1)		87,854			—		87,854
Prepayment penalty (1)		1,831			—		1,831
Closing Silver Legacy and Circus Reno net working capital (2)		6,124			2,111		8,235
Reverse member note (3)		(6,107	)		—		(6,107	)
Deferred tax liability		2,769			—		2,769
Purchase consideration	$	205,471		$	18,111	$	223,582

(1)

Represents $5.0 million of short-term debt, $75.5 million of long-term debt, the remaining 50% of the $11.5 million of member notes (net of discount), and accrued interest of $1.6 million. Additionally, the Company paid a $1.8 million prepayment penalty as a result of the early payoff of the Silver Legacy long-term debt.

(2)	Per the Purchase and Sale Agreement, the purchase price was $72.5 million plus the Final Closing Net Working Capital (as defined in the Purchase and Sale Agreement). As agreed by both parties, the final working capital adjustment was $8.2 million.

(3)	Represents 50% of the $11.5 million of member notes (net of discount) due to ERI, and related accrued interest. This amount was settled in conjunction with the final, agreed-upon purchase consideration.

The transaction was accounted for using the acquisition method. No goodwill resulted from the recording of this transaction.

The following table summarizes the allocation of the final purchase consideration to the identifiable assets acquired and liabilities assumed in the Circus Reno/Silver Legacy Purchase. The fair values were based on management’s analysis, including work performed by third‑party valuation specialists. The following table summarizes the final purchase price accounting of the acquired assets and assumed liabilities (dollars in thousands):

	Silver Legacy		Circus Reno		Total
Current and other assets, net	$	21,625	$	2,115	$	23,740
Property and equipment		168,037		14,996		183,033
Intangible assets (1)		5,000		1,000		6,000
Other noncurrent assets		10,809		—		10,809
Net assets acquired	$	205,471	$	18,111	$	223,582

(1)	Intangible assets consist of trade names which are non-amortizable and loyalty programs which were amortized over one year.

Valuation methodologies under both a market and income approach used for the identifiable net assets acquired in the Reno Acquisition make use of Level 1 and Level 3 inputs including quoted prices in active markets and discounted cash flows using current interest rates.

Trade receivables and payables, inventory as well as other current and noncurrent assets and liabilities were valued at the existing carrying values as they represented the fair value of those items at the Reno Acquisition Date, based on management’s judgments and estimates.

The fair value estimate of property and equipment utilized a combination of the cost and market approaches, depending on the characteristics of the asset classification. The fair value of land was determined using the market approach, which considers sales of comparable assets and applies compensating factors for any differences specific to the particular assets. With respect to personal property components of the assets (gaming equipment, furniture, fixtures and equipment, computers, and vehicles) the cost approach was used, which is based on replacement or reproduction costs of the asset. Building and site improvements were valued using the cost approach using a direct cost model built on estimates of replacement cost.

Trade names were valued using the relief‑from‑royalty method. The loyalty program was valued using a comparative business valuation method. Management has assigned trade names an indefinite useful life, in accordance with its review of applicable guidance of ASC Topic No. 350, Intangibles—Goodwill and Other. The standard required management to consider, among other things, the expected use of the asset, the expected useful life of other related asset or asset group, any legal, regulatory, or contractual provisions that may limit the useful life, the Company’s own historical experience in renewing similar arrangements, the effects of obsolescence, demand and other economic factors, and the maintenance expenditures required to obtain the expected cash flows. In that analysis, management determined that no legal, regulatory, contractual, competitive, economic or other factors limit the useful lives of these intangible assets. The loyalty program is being amortized on a straight‑line basis over a one year useful life.

For the period from the Reno Acquisition Date through December 31, 2015, the Silver Legacy generated net revenue of $13.5 million and a net loss of $0.3 million. Circus Reno generated net revenues of $8.3 million and net income of $1.4 million during the same period.

Reserve for Uncollectible Accounts Receivable

We reserve an estimated amount for receivables that may not be collected. Methodologies for estimating bad debt reserves range from specific reserves to various percentages applied to aged receivables. Historical collection rates are considered, as are customer relationships, in determining specific reserves. As with many estimates, management must make judgments about potential actions by third parties in establishing and evaluating our reserves for bad debts. In 2017 and 2016, the Company’s bad debt expense totaled $0.5 million and $0.2 million, respectively.

Hotel Partnership. The Company holds a 42.1% variable interest in a partnership with other investors that developed a new 118-room Hampton Inn & Suites hotel at Scioto Downs that opened in March 2017. Pursuant to the terms of the partnership agreement, the Company contributed $1.0 million of cash and 2.4 acres of a leasehold immediately adjacent to The Brew Brothers microbrewery and restaurant at Scioto Downs. The partnership constructed the hotel at a cost of $16.0 million and other investor members operate the hotel. In November 2017, the Company contributed $0.6 million to the partnership for its proportionate share of additional construction costs pursuant to the partnership agreement. At December 31, 2017 and 2016, the Company’s investment in the partnership was $1.5 million and $1.3 million, respectively, recorded in “Other Assets, Net” in the consolidated balance sheets, representing the Company’s maximum loss exposure. As of December 31, 2017, the Company’s receivable from the partnership totaled $0.2 million and is reflected on the accompanying balance sheet under “Due from Affiliates.”

Silver Legacy Joint Venture. Effective March 1, 1994, Eldorado Limited Liability Company (“ELLC”) and Galleon, Inc. entered into the Silver Legacy Joint Venture pursuant to a joint venture agreement (the “Joint Venture Agreement”) to develop the Silver Legacy.

As a result of these transactions, ELLC became a wholly-owned subsidiary of ERI and Silver Legacy became an indirect wholly‑owned subsidiary of ERI. In conjunction with the Reno Acquisition, we recorded a $35.6 million gain related to the valuation of the pre-acquisition investment in the Silver Legacy Joint Venture.

Equity in income related to the Silver Legacy Joint Venture for the 2015 period prior to the Reno Acquisition Date amounted to $3.5 million.

Goodwill is the excess of the purchase price of acquiring MTR Gaming and Isle over the fair market value of the net assets acquired.

Gaming licenses represent intangible assets acquired from the purchase of a gaming entity located in a gaming jurisdiction where competition is limited, such as when only a limited number of gaming operators are allowed to operate in the jurisdiction. These gaming license rights are not subject to amortization as the Company has determined that they have indefinite useful lives.

During the fourth quarter of 2017, the Company performed its annual impairment tests of its intangible assets by reviewing each of its reporting units. The goodwill analysis of the Company’s Lake Charles, Lula and Vicksburg reporting units indicated the fair value of Lake Charles’ and Vicksburg’s goodwill and all three reporting units’ trade names were less than their carrying values.

The Company adopted the new guidance under ASU No. 2017-04, which eliminated Step 2 from the impairment test. As a result of its analysis, the Company recorded a $38.0 million impairment charge in 2017 comprised of the following: $1.5 million, $0.3 million and $1.3 million related to trade names for Lake Charles, Lula and Vicksburg, respectively, and $11.7 million and $23.2 million related to goodwill for Lake Charles and Vicksburg, respectively.

The Company’s goodwill impairment charges in 2017 were primarily the result of expected decreases in future cash flows as a result of unfavorable economic conditions and the impact of changes in our competitors. The non-recurring fair values used in our determination of the goodwill impairment charges considered Level 2 and 3 inputs, including the review of comparable activities in the marketplace, discounted cash flows and market based multiple valuation methods.

The Company’s trade name impairment charges in 2017 were primarily the result of expected decreases in future net revenues. The non-recurring fair values used in our determination of the trade name impairment charges considered Level 2 and 3 inputs, including use of the relief‑from‑royalty method.

Amortization expense with respect to trade names and the loyalty program for the year ended December 31, 2017 and 2016 amounted to $5.1 million and $4.5 million, respectively, which is included in depreciation and amortization in the consolidated statements of income. Such amortization expense is expected to be $5.0 million, $4.6 million, and $1.5 million for the years ended December 31, 2018, 2019 and 2020, respectively.

In connection with the Isle Acquisition, the Company completed a debt financing transaction comprised of: (a) a senior secured credit facility in an aggregate principal amount of $1.75 billion with a (i) term loan facility of $1.45 billion and (ii) revolving credit facility of $300.0 million and (b) $375.0 million of 6% senior unsecured notes. The proceeds of such borrowings were used to pay the cash portion of the consideration payable in the Isle Merger, refinance all of Isle’s existing credit facilities, redeem or otherwise repurchase all of Isle’s and senior and senior subordinated notes, refinance the Company’s existing credit facility and pay transaction fees and expenses related to the foregoing.

On September 13, 2017, the Company issued an additional $500.0 million in aggregate principal amount of its 6% Senior Notes (as defined below) at an issue price equal to 105.5% of the principal amount. The 6% Senior Notes were issued as additional notes under the 6% Senior Notes Indenture dated March 29, 2017 (as defined below), as supplemented by the supplemental indenture dated as of May 1, 2017 between the Company, the guarantors party thereto and U.S. Bank National Association, pursuant to which the Company previously issued $375.0 million aggregate principal amount of 6% Senior Notes. The additional 6% Senior Notes formed part of a single class of securities together with the initial 6% Senior Notes for all purposes under the 6% Senior Notes Indenture, including waivers, amendments, redemptions and offers to purchase.

The Company used the proceeds of the offering to repay all of the outstanding borrowings under the New Revolving Credit Facility (as defined below) totaling $78.0 million and used the remainder to repay outstanding borrowings totaling $444.5 million under the New Term Loan plus related accrued interest.

Amortization of the debt issuance costs and the discount and premium associated with our indebtedness totaled $6.3 million and $3.5 million for the years ended December 31, 2017 and 2016, respectively. Amortization of debt issuance costs is computed using the effective interest method and is included in interest expense. Amortization expense with respect to deferred financing costs on the Company’s senior secured notes amounted to $0.5 million for year ended December 31, 2015.

In accordance with ASC Topic 470-50, “Debt Modifications and Extinguishments” (“ASC 470-50”), the Company recognized a loss totaling $27.3 million for the year ended December 31, 2017 as a result of the refinance of the Prior Credit Facility (as defined below) in May 2017. The Company also recognized a loss totaling $11.1 million as a result of the issuance of additional 6% Senior Notes in September 2017 resulting in a combined total loss of $38.4 million for the year ended December 31, 2017.

Scheduled maturities of long‑term debt are $375.0 million in 2023, $956.8 million in 2024, and $875.0 million in 2025.

The Company is a holding company with no independent assets or operations. Our 6% Senior Notes and 7% Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by the subsidiary guarantors. As of December 31, 2017, there were no significant restrictions on the ability of our subsidiaries to distribute cash to us or our guarantor subsidiaries.

In accordance with ASC 840, the Company was deemed, for accounting purposes only, to be the owner of these assets provided by the Resort during the construction and casino operating periods due to the Company’s continuing involvement. Therefore, the transaction was accounted for using the direct financing method. As of December 31, 2017, the Company recorded property and equipment, net of accumulated depreciation, of $4.2 million, and a liability of $4.5 million in other long-term liabilities related to the agreement.

Refinancing of the Term Loan and Revolving Credit Facility

Credit Facility

On July 23, 2015, the Company entered into a new $425.0 million seven year term loan (the “Term Loan”) and a $150.0 million five year revolving credit facility (the “Prior Revolving Credit Facility” and, together with the Term Loan, the “Prior Credit Facility”).

The Term Loan bore interest at a rate per annum of, at the Company’s option, either LIBOR plus 3.25%, with a LIBOR floor of 1.0%, or a base rate plus 2.25%. Borrowings under the Prior Revolving Credit Facility bore interest at a rate per annum of, at the Company’s option, either LIBOR plus a spread ranging from 2.5% to 3.25% or a base rate plus a spread ranging from 1.5% to 2.25%, in each case with the spread determined based on the Company’s total leverage ratio. Additionally, the Company paid a commitment fee on the unused portion of the Prior Revolving Credit Facility not being utilized in the amount of 0.50% per annum.

On May 1, 2017, all of the outstanding amounts under the Prior Credit Facility were repaid with proceeds of borrowings under the New Credit Facility and the Prior Credit Facility was terminated.

New Credit Facility

On April 17, 2017, Eagle II entered into a new credit agreement by and among Eagle II, as initial borrower, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto dated as of April 17, 2017 (the “New Credit Facility”), consisting of a $1.45 billion term loan facility (the “New Term Loan Facility” or “New Term Loan”) and a $300.0 million revolving credit facility (the “New Revolving Credit Facility”), which was undrawn at closing. The proceeds of the New Term Loan Facility, and additional funds in the amount of $4.5 million in respect of interest expected to be accrued on the New Term Loan Facility, were placed in escrow pending satisfaction of certain conditions, including consummation of the Isle Acquisition. In connection with the consummation of the Isle Acquisition on May 1, 2017, the escrowed funds were released and ERI assumed Eagle II’s obligations under the New Credit Facility and certain of ERI’s subsidiaries (including Isle and certain of its subsidiaries) executed guarantees of ERI’s obligations under the New Credit Facility.

As of December 31, 2017, the Company had $956.8 million outstanding on the New Term Loan. There were no borrowings outstanding under the New Revolving Credit Facility as of December 31, 2017. The Company had $291.6 million of available borrowing capacity, after consideration of $8.4 million in outstanding letters of credit, under its New Revolving Credit Facility as of December 31, 2017. At December 31, 2017, the weighted average interest rate on the New Term Loan was 3.6%, and the weighted average interest rate on the New Revolving Credit Facility was 4.0% based upon the weighted average interest rate of borrowings outstanding during 2017.

The Company applied the net proceeds of the New Term Loan Facility and borrowings under the New Revolving Credit Facility, together with the proceeds of the 6% Senior Notes and cash on hand, to (i) pay the cash portion of the consideration payable in the Isle Merger, (ii) refinance all of the debt outstanding under Isle’s existing credit facility, (iii) redeem or otherwise repurchase all of Isle’s outstanding senior and senior subordinated notes, (iv) refinance the Company’s Prior Credit Facility and (v) pay fees and costs associated with the foregoing.

The Company’s obligations under the New Revolving Credit Facility will mature on April 17, 2022. The Company’s obligations under the New Term Loan Facility will mature on April 17, 2024. The Company was required to make quarterly principal payments in an amount equal to $3.6 million on the New Term Loan Facility on the last day of each fiscal quarter beginning on June 30, 2017 but satisfied this requirement as a result of the principal prepayment of $444.5 million on September 13, 2017 in conjunction with the issuance of the additional 6% Senior Notes. In addition, the Company is required to make mandatory payments of amounts outstanding under the New Credit Facility with the proceeds of certain casualty events, debt issuances, and asset sales and, depending on its consolidated total leverage ratio, the Company may be required to apply a portion of its excess cash flow to repay amounts outstanding under the New Credit Facility.

The interest rate per annum applicable to loans under the New Revolving Credit Facility are, at our option, either (i) LIBOR plus a margin ranging from 1.75% to 2.50% or (ii) a base rate plus a margin ranging from 0.75% to 1.50%, which margin is based on our total leverage ratio. The interest rate per annum applicable to the loans under the New Term Loan Facility is, at our option, either (i) LIBOR plus 2.25%, or (ii) a base rate plus 1.25%; provided, however, that in no event will LIBOR be less than zero or the base rate be less than 1.00% over the term of the New Term Loan Facility or the New Revolving Credit Facility. Additionally, the Company pays a commitment fee on the unused portion of the New Revolving Credit Facility not being utilized in the amount of 0.50% per annum.

The New Credit Facility contains a number of customary covenants that, among other things, restrict, subject to certain exceptions, the Company’s ability and the ability of the subsidiary guarantors to incur debt; create liens; engage in mergers, consolidations or asset dispositions; pay dividends or make distributions; make investments, loans or advances; engage in certain transactions with affiliates or subsidiaries; or modify their lines of business.

The New Credit Facility is secured by substantially all of the Company’s personal property assets and substantially all personal property assets of each subsidiary that guaranties the New Credit Facility (other than certain subsidiary guarantors designated as immaterial) (the “New Credit Facility Guarantors”), whether owned on the closing date of the New Credit Facility or thereafter acquired, and mortgages on the real property and improvements owned or leased us or the New Credit Facility Guarantors. The New Credit Facility is also secured by a pledge of all of the equity owned by the Company and the New Credit Facility Guarantors (subject to certain gaming law restrictions). The credit agreement governing the New Credit Facility contains a number of customary covenants that, among other things, restrict, subject to certain exceptions, the Company’s ability and the ability of the New Credit Facility Guarantors to incur additional indebtedness, create liens, engage in mergers, consolidations or asset dispositions, make distributions, make investments, loans or advances, engage in certain transactions with affiliates or subsidiaries or make capital expenditures.

The New Credit Facility also includes certain financial covenants, including the requirements that we maintain throughout the term of the New Credit Facility and measured as of the end of each fiscal quarter, and solely with respect to loans under the New Revolving Credit Facility, a maximum consolidated total leverage ratio of not more than 6.50 to 1.00 for the period beginning on the closing date and ending with the fiscal quarter ending December 31, 2018, 6.00 to 1.00 for the period beginning with the fiscal quarter beginning January 1, 2019 and ending with the fiscal quarter ending December 31, 2019, and 5.50 to 1.00 for the period beginning with the fiscal quarter beginning January 1, 2020 and thereafter. The Company will also be required to maintain an interest coverage ratio in an amount not less than 2.00 to 1.00 measured on the last day of each fiscal quarter beginning on the closing date, and ending with the fiscal quarter ending December 31, 2018, 2.50 to 1.00 for the period beginning with the fiscal quarter beginning January 1, 2019 and ending with the fiscal quarter ending December 31, 2019, and 2.75 to 1.00 for the period beginning with the fiscal quarter beginning January 1, 2020 and thereafter.

The New Credit Facility contains a number of customary events of default, including, among others, for the non-payment of principal, interest or other amounts, the inaccuracy of certain representations and warranties, the failure to perform or observe certain covenants, a cross default to our other indebtedness including the Notes, certain events of bankruptcy or insolvency; certain ERISA events, the invalidity of certain loan documents, certain changes of control and the loss of certain classes of licenses to conduct gaming. If any event of default occurs, the lenders under the New Credit Facility would be entitled to take various actions, including accelerating amounts outstanding thereunder and taking all actions permitted to be taken by a secured creditor. As of December 31, 2017, the Company was in compliance with the covenants under the New Credit Facility.

Income Taxes

Note 10. Income Taxes

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) eliminating the corporate alternative minimum tax (AMT) and changing how existing AMT credits can be realized; (3) creating a new limitation on deductible interest expense; (4) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017; (5) bonus depreciation that will allow for full expensing of qualified property; and (6) limitations on the deductibility of certain executive compensation.

The SEC staff issued Staff Accounting Bulletin (“SAB”) 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

In connection with our initial analysis of the impact of the Tax Act, for certain of our net deferred tax liabilities, we have recorded a decrease of $112.4 million, net of the related change in valuation allowance, with a corresponding net adjustment to deferred income tax benefit for the year ending December 31, 2017 as a result of the corporate rate reduction. While we were able to make a reasonable estimate of the impact of the reduction in the corporate rate, it may be affected by other analyses related to the Tax Act, including, but not limited to additional guidance issued by the U.S. Treasury Department and the Internal Revenue Service regarding compensation deferred taxes, as well as the state tax effect of adjustments made to federal temporary differences.

While we have not yet completed all of the computations necessary or completed an inventory of our 2017 expenditures that qualify for immediate expensing, we have recorded a provisional benefit based on our current intent to fully expense all qualifying expenditures. This did not result in any significant change to our current income tax payable or in our deferred tax liabilities due to our federal and state net operating loss carry forwards.

The components of the Company’s provision for income taxes for the years ended December 31, 2017, 2016 and 2015 are presented below (amounts in thousands).

The following is a reconciliation of the statutory federal income tax rate to the Company’s effective tax rate for the years ended December 31, 2017, 2016 and 2015:

	2017				2016				2015
Federal statutory rate		35.0		%		35.0		%		35.0		%

Effective income tax rate		270.6		%		34.8		%		(156.0	)	%

For the year ended December 31, 2017, the difference between the effective rate and the statutory rate is attributable primarily to the impact of the Tax Act discussed more fully below, non-deductible asset impairment charges and non-deductible transaction costs incurred and changes in the effective state tax rate associated with the acquisition of Isle of Capri. The Company continues to provide for a valuation allowance against net federal and state deferred tax assets associated with non-operating land, the sale of which could result in capital losses that can only be offset against capital gains. The Company also continues to provide for a valuation allowance against net state deferred tax assets relating to certain operations in Pennsylvania, Louisiana, Colorado and Iowa. Management determined it was not more-likely-than-not that the Company will realize these net deferred tax assets.

For the year ended December 31, 2016, the difference between the effective rate and the statutory rate is attributable primarily to the release of a majority of the state valuation allowances on the Company’s West Virginia deferred tax assets and excess tax benefits on stock compensation under Accounting Standards Update 2016-09, Compensation – Stock Compensation, which the Company adopted effective the first quarter of 2016. The Company continues to provide for a valuation allowance against net federal and state deferred tax assets associated with non-operating land, the sale of which could result in capital losses that can only be offset against capital gains. As of December 31, 2016, the Company also continued to provide for a valuation allowance against net state deferred tax assets relating to operations in Pennsylvania. Management determined it was not more-likely-than-not that the Company will realize these net deferred tax assets.

For the year ended December 31, 2015, the difference between the effective rate and the statutory rate is attributable primarily to the release of a majority of the federal and related state valuation allowances on the Company’s deferred tax assets and the non-taxable gain on the fair value adjustment of a previously unconsolidated affiliate. The Company continues to provide for a valuation allowance against net federal and state deferred tax assets associated with non-operating land, the sale of which could result in capital losses that can only be offset against capital gains. As of December 31, 2015, the Company also continued to provide for a valuation allowance against net state deferred tax assets relating to operations in Pennsylvania and West Virginia. Management determined it was not more-likely-than-not that the Company will realize these net deferred tax assets.

A valuation allowance is recognized if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax asset will not be realized. Management must analyze all available positive and negative evidence regarding realization of the deferred tax assets and make an assessment of the likelihood of sufficient future taxable income. For the year ended December 31, 2015, the Company was in a three-year cumulative income position and management concluded it was more-likely-than-not to realize its federal, Louisiana and City of Columbus, Ohio deferred tax assets, with the exception of non-operating land. The recognition of the federal deferred tax assets during 2015 resulted in an income tax benefit of $80.3 million. For the year ended December 31, 2016, the Company remained in a three-year cumulative income position and management concluded it was more-likely-than-not to realize its federal, Louisiana, City of Columbus, Ohio and West Virginia deferred tax assets, with the exception of non-operating land. The recognition of the West Virginia deferred tax assets during 2016 resulted in an income tax benefit of $1.4 million. For the year ended December 31, 2017, the Company remained in a three-year cumulative income position and management concluded it is more-likely-than-not to realize its federal, City of Columbus, Ohio, City of Kansas City, Missouri, West Virginia, Missouri and certain Pennsylvania, Colorado and Florida deferred tax assets, with the exception of non-operating land. The recognition of the Pennsylvania deferred tax assets during 2017 resulted in an income tax benefit of $5.2 million. Management has determined that it is not more-likely-than-not that the Company will realize certain of its Pennsylvania, Louisiana, Colorado and Iowa deferred tax assets. Therefore, a full valuation allowance has been recognized against these deferred tax assets, excluding deferred tax liabilities related to indefinite‑lived assets. These indefinite‑lived assets primarily related to gaming licenses in various jurisdictions. These gaming licenses are not being amortized for book purposes, and will only reverse upon ultimate sale or book impairment. Due to the uncertain timing of such reversal, the temporary differences associated with indefinite‑lived intangibles and certain land improvements cannot be considered a source of future taxable income for purposes of determining the valuation allowance. The Company will continue to evaluate the realization of its deferred tax assets on a quarterly basis and make adjustments to its valuation allowance as appropriate.

On November 24, 2015, Eldorado Resorts LLC, an indirect wholly-owned subsidiary of ERI, acquired the additional 50% membership interest in the Silver Legacy Joint Venture partnership. Prior to the 2015 acquisition, a deferred tax asset was recognized to the extent that the tax basis in the partnership interest exceeded the book basis. As a result of the 2015 acquisition, the partnership ceased to exist and the Company wrote off the outside basis deferred tax asset of $8.1 million as a change in tax status.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred taxes related to continuing operations at December 31, 2016 and 2015 are as follows (amounts in thousands):

	2017			2016
Deferred tax assets:
Loss carryforwards	$	58,245		$	38,377
Accrued expenses		9,633			7,748

As of December 31, 2017, the Company had federal and state net operating loss carryforwards of $147.2 million and $387.7 million, respectively. The federal and state net operating losses begin to expire in 2030 and 2018, respectively. As of December 31, 2017, the Company had federal jobs credit carry forwards of $19.6 million, which begin to expire in 2024.

Utilization of net operating loss, credit, and other carryforwards are subject to annual limitations due to ownership changes as provided by the Internal Revenue Code of 1986, as amended and similar state provisions. An ownership change is defined as a greater than 50% change in ownership by 5% stockholders in any three‑year period. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, the Company had a “change in ownership” event that limits the utilization of net operating loss, credit, and other carryforwards that were previously available to MTR, Isle of Capri and the Company to offset future taxable income. The “change in ownership” event for MTR occurred on September 19, 2014 in connection with the MTR Merger. The “change in ownership” event for Isle of Capri and the Company occurred on May 1, 2017 in connection with the merger with Isle of Capri. This limitation resulted in no significant loss of federal attributes, but did result in significant loss of state attributes. The federal and state net operating loss credit and other carryforwards are stated net of limitations.

As of December 31, 2017, there were no unrecognized tax benefits and the Company does not expect a significant increase or decrease to the total amounts of unrecognized tax benefits within the next twelve months. We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense.

The Company and its subsidiaries file US federal income tax returns and various state and local income tax returns. The Company does not have tax sharing agreements with the other members within the consolidated ERI group. With few exceptions, the Company is no longer subject to US federal or state and local tax examinations by tax authorities for years before 2012.

The Company was notified by the Internal Revenue Service in October of 2016 that its federal tax return for the year ended December 31, 2014 had been selected for examination. In September 2017, the IRS informed the Company that they completed the examination of the tax return and made no changes. However, the Company may be subject to audit in the future and the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with the Company’s expectations, we would be required to adjust our provision for income taxes in the period such resolution occurs. While the Company believes its reported results are materially accurate, any significant adjustments could have a material adverse effect on the Company’s results of operations, cash flows and financial position.

Employee Benefit Plans	12 Months Ended
Employee Benefit Plans	Dec. 31, 2017
Employee Benefits And Share Based Compensation [Abstract]
Employee Benefit Plans	Note 11. Employee Benefit Plans Effective January 1, 2016, the Company elected to merge the plan assets of all its wholly-owned subsidiaries into the MTR Gaming Group, Inc. Retirement Plan (the “MTR Retirement Plan”) and renamed it the Eldorado Resorts, Inc. 401(k) Plan (“ERI 401(k) Plan”). As a result, assets of the Eldorado Hotel & Casino Master 401(k) Plan, the Silver Legacy 401(k) Plan and Circus Circus Reno MGM Resorts 401(k) Savings Plan transferred in the ERI 401(k) Plan. Generally, all employees of ERI who are 21 years of age or older, who have completed six months and 1,000 hours of service and who are not covered by collective bargaining agreements, including the named executive officers, are eligible to participate in the ERI 401(k) Plan. Employees who elect to participate in the ERI 401(k) Plan could defer up to 100% but not less than 1% of their annual compensation, subject to statutory and certain other limits. The plan covering ERI’s employees allows for an employer contribution up to 50 percent of the first four percent of each participating employee’s contribution, up to a maximum of $1,000, subject to statutory and certain other limits. ERI’s matching contributions totaled $1.6 million and $1.5 million for the years ended December 31, 2017 and 2016, respectively. Prior to 2016, the Resorts’ 401 (k) plan participated in a multi-employer savings plan (the “401(k) Plan”) qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended. The 401(k) Plan in which Resorts participated functioned as an aggregation of several single-employer plans in order to enable the participating employers to pool plan assets for investment purposes and to reduce the costs of plan administration. The 401(k) Plan maintained separate accounts for each employer so that each employer’s contributions provided benefits only for its employees. Generally, all employees of Resorts who were 21 years of age or older, who had completed six months and 1,000 hours of service and who were not covered by collective bargaining agreements, including the named executive officers, were eligible to participate in the 401(k) Plan. Employees who elected to participate in the 401(k) Plan could defer up to 100% but not less than 1% of their annual compensation, subject to statutory and certain other limits. Effective February 1, 2014, Eldorado Reno implemented an employer matching contribution up to 25 percent of the first four percent of each participating employee’s compensation. Employees of the Eldorado Shreveport also participated in Resorts’ 401(k) Plan. The plan covering Eldorado Shreveport’s employees allowed for an employer contribution up to 50 percent of the first six percent of each participating employee’s contribution, subject to statutory and certain other limits. Resorts’ matching contributions totaled $0.5 million for the year ended December 31, 2015. Isle has a 401(k) plan covering substantially all of its employees who have completed 90 days of service. Expense for contributions from continuing operations related to the 401(k) plan was $1.0 million or the 2017 period subsequent to the Isle Acquisition Date. Isle’s contribution is based on a percentage of employee contributions and may include an additional discretionary amount. Previously MTR Gaming participated in the MTR Retirement Plan. At that time, the Mountaineer qualified defined contribution plan and the Scioto Downs’ 401(k) plan were merged into the MTR Retirement Plan. Additionally, the MTR Retirement Plan provided 401(k) participation to Presque Isle Downs’ employees. Matching contributions by MTR Gaming were $0.1 million for 2015. Mountaineer’s qualified defined contribution plan (established by West Virginia legislation) covers substantially all of its employees and was merged as a component of the MTR Retirement Plan as previously discussed. Contributions to the plan are based on 1/4% of the race track and simulcast wagering handles and approximately 1% of the net win from gaming operations until the racetrack reaches its Excess Net Terminal Income threshold, which for Mountaineer is approximately $160 million per year based on the state’s June 30 fiscal year. Contributions to the ERI 401(k) Plan for the benefit of Mountaineer employees were $1.1 million, $1.2 million and $1.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. Scioto Downs sponsors a noncontributory defined-benefit plan covering all full-time employees meeting certain age and service requirements. On May 31, 2001, the plan was amended to freeze eligibility, accrual of years of service and benefits. As of December 31, 2017, the fair value of the plan assets was $1.2 million and the fair value of the benefit obligations was $0.8 million, resulting in an over-funded status of $0.4 million. The plan assets are comprised primarily of money market and mutual funds whose values are determined based on quoted market prices and are classified in Level 1 of the fair value hierarchy. We did not make cash contributions to the Scioto Downs pension plan during 2017, 2016 and 2015.

Share Based Compensation [Abstract]

Stock-Based Compensation

Note 12. Stock-Based Compensation

Common Stock and Stock‑Based Awards

The Company has authorized common stock of 100,000,000 shares, par value $0.00001 per share.

The Company accounts for stock-based compensation in accordance with ASC 718, Compensation—Stock Compensation. Total stock-based compensation expense in the accompanying consolidated statements of income was $6.3 million, $3.3 million and $1.5 million during the years ended December 31, 2017, 2016 and 2015, respectively.

The Board of Directors (“BOD”) adopted the Eldorado Resorts, Inc. 2015 Equity Incentive Plan (“2015 Plan”) on January 23, 2015 and our stockholders subsequently approved the adoption of the 2015 Plan on June 23, 2015. The Plan permits the granting of stock options, including incentive stock options (“ERI Stock Options”), stock appreciation rights, restricted stock or restricted stock units (“RSUs”), performance awards, and other stock-based awards and dividend equivalents. ERI Stock Options primarily vest ratably over three years and RSUs granted to employees and executive officers primarily vest and become non-forfeitable upon the third anniversary of the date of grant. RSUs granted to non-employee directors vest immediately and are delivered upon the date that is the earlier of termination of service on the BOD or the consummation of a change of control of the Company. The performance awards relate to the achievement of defined levels of performance and are generally measured over a one or two-year performance period depending upon the award agreement. If the performance award levels are achieved, the awards earned will vest and become payable at the end of the vesting period, defined as either a one or two calendar year period following the performance period. Payout ranges are from 0% up to 200% of the award target.

Pursuant to the Merger Agreement, the outstanding equity awards of Isle were converted into comparable equity awards of ERI stock as follows:

Isle stock options. Each option or other right to acquire Isle common stock (each an “Isle Stock Option”) that was outstanding immediately prior to the Isle Acquisition Date (whether vested or unvested), as of the Isle Acquisition Date, (i) continued to vest or accelerate (if unvested), as the case may be, in accordance with the applicable Isle stock plan, the award agreement pursuant to which such Isle Stock Option was granted and, if applicable, any other relevant agreements (such as an employment agreement), (ii) ceased to represent an option or right to acquire shares of Isle common stock, and (iii) was converted into an option or right to purchase that number of shares ERI common stock equal to the number of shares of Isle common stock subject to the Isle Stock Option multiplied by the Stock Consideration at an exercise price equal to the exercise price of the Isle Stock Option divided by the Stock Consideration, subject to the same restrictions and other terms as are set forth in the Isle equity incentive plan, the award agreement pursuant to which such Isle Stock Option was granted and, if applicable, any other relevant agreements (such as an employment agreement).

Isle restricted stock awards. Each share of Isle common stock subject to vesting, repurchase or lapse restrictions (each an “Isle Restricted Share”) that was outstanding under any Isle equity plan or otherwise immediately prior to the Isle Acquisition Date, as of the Isle Acquisition Date, continued to vest or accelerate (if unvested), as the case may be, in accordance with the applicable Isle stock plan, the award agreement pursuant to which such Isle Restricted Share was granted, and, if applicable, any other relevant agreements (such as an employment agreement) and was exchanged for shares of ERI common stock (in an amount equal to the Stock Consideration, with aggregated fractional shares rounded to the nearest whole share) and remain subject to the same restrictions and other terms as are set forth in the Isle stock plan, the award agreement pursuant to which such Isle Restricted Share was granted, and, if applicable, any other relevant agreements (such as an employment agreement).

Isle performance stock units.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 15. Fair Value Measurements

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Accordingly, fair value is a market based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, there is a three‑tier fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows:

•

Level 1 Inputs: Quoted market prices in active markets for identical assets or liabilities.

•

Level 2 Inputs: Observable market‑based inputs or unobservable inputs that are corroborated by market data.

•

Level 3 Inputs: Unobservable inputs that are not corroborated by market data.

Items Measured at Fair Value on a Recurring Basis: The following table sets forth the assets measured at fair value on a recurring basis, by input level, in the consolidated balance sheets at December 31, 2017:

	December 31, 2017
	Level 1		Level 2		Total
Assets:
Marketable securities	$	7,906	$	9,725	$	17,631
Restricted cash and investments		9,055		4,098		13,153

The following methods and assumptions are used to estimate the fair value of each class of financial instruments for which it is practical to estimate fair value:

Cash and Cash Equivalents: Cash equivalents include investments in money market funds. Investments in this category can be redeemed immediately at the current net asset value per share. A money market fund is a mutual fund whose investments are primarily in short‑term debt securities designed to maximize current income with liquidity and capital preservation, usually maintaining per share net asset value at a constant amount, such as one dollar. Cash and cash equivalents also includes cash maintained for gaming operations. The carrying amounts approximate the fair value because of the short maturity of those instruments (Level 1).

Restricted Cash: Restricted cash includes cash reserved for unredeemed winning tickets from the Company’s racing operations, funds related to horsemen’s fines and certain simulcasting funds that are restricted to payments for improving horsemen’s facilities and racing purses, cash deposits that serve as collateral for letters of credit, surety bonds and short-term certificates of deposit that serve as collateral for certain bonding requirements. The estimated fair values of our restricted cash and investments are based upon quoted prices available in active markets (Level 1), or quoted prices for similar assets in active and inactive markets (Level 2), and represent the amounts we would expect to receive if we sold our restricted cash and investments. Restricted investments, included in Other Assets, net, relate to trading securities pledged as collateral by our captive insurance company.

Accounts Receivable and Credit Risk: The allowance is estimated based on specific review of customer accounts as well as historical collection experience and current economic and business conditions. Management believes that no significant concentrations of credit risk related to receivables existed.

Marketable Securities: Marketable securities consist primarily of trading securities held the Company’s captive insurance subsidiary. The estimated fair values of the Company’s marketable securities are determined on an individual asset basis based upon quoted prices of identical assets available in active markets (Level 1), quoted prices of identical assets in inactive markets, or quoted prices for similar assets in active and inactive markets (Level 2), and represent the amounts we would expect to receive if we sold these marketable securities.

Long‑term Debt: The fair value of our long-term debt or other long-term obligations is estimated based on the quoted market price of the underlying debt issue (Level 1) or, when a quoted market price is not available, the discounted cash flow of future payments utilizing current rates available to us for the debt of similar remaining maturities (Level 2). Debt obligations with a short remaining maturity have a carrying amount that approximates fair value.

Acquisition‑Related Contingent Considerations: Contingent consideration related to the July 2003 acquisition of Scioto Downs represents the estimate of amounts to be paid to former stockholders of Scioto Downs under certain earn-out provisions. The Company considers the acquisition related contingency’s fair value measurement, which includes forecast assumptions, to be Level 3 within the fair value hierarchy. Acquisition related contingent considerations is included in accrued other liabilities on the consolidated balance sheets.

There were no transfers between Level 1 and Level 2 investments.

The estimated fair values of the Company’s financial instruments are as follows (amounts in thousands):

	December 31, 2017				December 31, 2016
	Carrying		Fair		Carrying		Fair
	Amount		Value		Amount		Value

The future minimum lease payments, including interest, at December 31, 2017 are $0.6 million, $0.4 million, and $0.1 million in 2018, 2019, and 2020, respectively. After reducing these amounts for interest of $0.2 million, the present value of the minimum lease payments at December 31, 2017 is $0.9 million.

Operating Leases. The Company leases land and certain equipment, including some of our slot machines, timing and photo finish equipment, videotape and closed circuit television equipment, and certain pari‑mutuel equipment, under operating leases. Future minimum payments under non‑cancellable operating leases with initial terms of one year or more consisted of the following at December 31, 2017 (in thousands):

Total rental expense under operating leases totaled $28.2 million, $17.0 million and $14.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. Included in the $28.2 million is rent for land upon which the Eldorado Reno resides of $0.6 million in each of the years ended December 31, 2017, 2016 and 2015 which was paid to C. S. & Y. Associates which is an entity partially owned by Recreational Enterprises, Inc. (“REI”). The Company’s Chief Executive Officer and Chairman of the Board, Gary L. Carano, and its Senior Vice President of Regional operations, Gene Carano, are the directors of REI and members of the Carano family, including Gary L. Carano and Gene Carano, own the equity interests in REI. This rental agreement expires June 30, 2027 and the rental payments are more fully described in Note 17, Related Affiliates.

Litigation. The Company is a party to various legal and administrative proceedings, which have arisen in the normal course of its business. Estimated losses are accrued for these proceedings when the loss is probable and can be estimated. The current liability for the estimated losses associated with these proceedings is not material to the Company’s consolidated financial condition and those estimated losses are not expected to have a material impact on its results of operations. In addition, the Company maintains what it believes is adequate insurance coverage to further mitigate the risks of such proceedings. However, such proceedings can be costly, time consuming and unpredictable and, therefore, no assurance can be given that the final outcome of such proceedings may not materially impact the Company’s consolidated financial condition or results of operations. Further, no assurance can be given that the amount of scope of existing insurance coverage will be sufficient to cover losses arising from such matter.

Collective Bargaining Agreements. As of December 31, 2017, we had approximately 12,500 employees. As of such date, we had 11 collective bargaining agreements covering approximately 970 employees. Three collective bargaining agreements are scheduled to expire in 2018. There can be no assurance that we will be able to extend or enter into replacement agreements. If we are able to extend or enter into replacement agreements, there can be no assurance as to whether the terms will on comparable terms to the existing agreements.

Agreements with Horsemen and Pari-mutuel Clerks. The Federal Interstate Horse Racing Act and the state racing laws in West Virginia, Ohio and Pennsylvania require that, in order to simulcast races, we have written agreements with the horse owners and trainers at those racetracks. In addition, in order to operate slot machines in West Virginia, we are required to enter into written agreements regarding the proceeds of the slot machines (a “proceeds agreement”) with a representative of a majority of the horse owners and trainers and with a representative of a majority of the pari‑mutuel clerks. In Pennsylvania and Ohio, we must have an agreement with the representative of the horse owners. We have the requisite agreements in place with the horsemen at Mountaineer until December 31, 2018. With respect to the Mountaineer pari‑mutuel clerks, we have a labor agreement in force until November 30, 2018, which will automatically renew for an additional one-year period, and a proceeds agreement until April 14, 2018. We are required to have a proceeds agreement in effect on July 1 of each year with the horsemen and the pari‑mutuel clerks as a condition to renewal of our video lottery license for such year. If the requisite proceeds agreement is not in place as of July 1 of a particular year, Mountaineer’s application for renewal of its video lottery license could be denied, in which case Mountaineer would not be permitted to operate either its slot machines or table games. Scioto Downs has the requisite agreement in place with the OHHA until December 31, 2023, with automatic two‑year renewals unless either party requests re‑negotiation pursuant to its terms. Presque Isle Downs has the requisite agreement in place with the Pennsylvania Horsemen’s Benevolent and Protective Association until May 1, 2019. With the exception of the respective Mountaineer, Presque Isle Downs and Scioto Downs horsemen’s agreements and the agreement between Mountaineer and the pari‑mutuel clerks’ union described above, each of the agreements referred to in this paragraph may be terminated upon written notice by either party.

The executive decision maker of our Company reviews operating results, assesses performance and makes decisions on a “significant market” basis. Management views each of our casinos as an operating segment. Operating segments are aggregated based on their similar economic characteristics, types of customers, types of services and products provided, and their management and reporting structure. Prior to the Isle Acquisition, the Company’s principal operating activities occurred in three geographic regions: Nevada, Louisiana and parts of the eastern United States. The Company aggregated its operations into three reportable segments based on the similar characteristics of the operating segments within the regions in which they operated as follows:

Segment	Property	State
Nevada	Eldorado Reno	Nevada
	Silver Legacy	Nevada
	Circus Reno	Nevada

Louisiana	Eldorado Shreveport	Louisiana

Eastern	Presque Isle Downs	Pennsylvania
	Scioto Downs	Ohio
	Mountaineer	West Virginia

Following the Isle Acquisition, the Company’s principal operating activities expanded and now occur in four geographic regions and reportable segments based on the similar characteristics of the operating segments within the regions in which they operate. The following table summarizes our current segments:

Segment	Property	State
West	Eldorado Reno	Nevada
	Silver Legacy	Nevada
	Circus Reno	Nevada
	Isle Black Hawk	Colorado
	Lady Luck Black Hawk	Colorado

Midwest	Waterloo	Iowa
	Bettendorf	Iowa
	Boonville	Missouri
	Cape Girardeau	Missouri
	Caruthersville	Missouri
	Kansas City	Missouri

South	Pompano	Florida
	Eldorado Shreveport	Louisiana
	Lake Charles	Louisiana
	Lula	Mississippi
	Vicksburg	Mississippi

East	Presque Isle Downs	Pennsylvania
	Nemacolin	Pennsylvania
	Scioto Downs	Ohio
	Mountaineer	West Virginia

The following table sets forth, for the periods indicated, certain operating data for our four reportable segments. Amounts related to pre-acquisition periods (prior to May 1, 2017) conform to prior presentation as the additional operating segments associated with the Isle Acquisition are incremental to the previously disclosed reportable segments.

Operating loss carryforwards, limitations		Utilization of net operating loss, credit, and other carryforwards are subject to annual limitations due to ownership changes as provided by the Internal Revenue Code of 1986, as amended and similar state provisions. An ownership change is defined as a greater than 50% change in ownership by 5% stockholders in any threeyear period. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, the Company had a “change in ownership” event that limits the utilization of net operating loss, credit, and other carryforwards that were previously available to MTR, Isle of Capri and the Company to offset future taxable income. The “change in ownership” event for MTR occurred on September 19, 2014 in connection with the MTR Merger. The “change in ownership” event for Isle of Capri and the Company occurred on May 1, 2017 in connection with the merger with Isle of Capri. This limitation resulted in no significant loss of federal attributes, but did result in significant loss of state attributes. The federal and state net operating loss credit and other carryforwards are stated net of limitations.
