PROSPECTUS SUPPLEMENT

4,000,000 Shares

Class A Common Stock

We are offering 2,000,000 shares of our Class A common stock in this offering. The selling stockholders, consisting of certain of our former and current employees and members of our management, are selling 2,000,000 shares of Class A common stock in this offering.

We intend to use the net proceeds received by us in this offering to acquire on April 5, 2018 a number of shares of our Class B common stock from ORIX HLHZ Holding LLC equal to the number of shares of Class A common stock sold by us in this offering at a purchase price per share equal to the public offering price in this offering less underwriting discounts and commissions, in a transaction to which we refer in this prospectus supplement as the forward repurchase.

We will not receive any of the proceeds from the sale of our Class A common stock by the selling stockholders in this offering.

We have two classes of authorized common stock, Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock are identical, except with respect to voting and conversion rights. Each share of Class A common stock is entitled to one vote per share. Each share of Class B common stock is entitled to ten votes per share and is convertible into one share of Class A common stock. Outstanding shares of Class B common stock will represent approximately 92.4% of the voting power of our outstanding capital stock immediately following the completion of this offering, and 92.0% of the voting power of our outstanding capital stock immediately following the settlement of the forward repurchase.

Our Class A common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “HLI.” The last reported sale price of our Class A common stock on the NYSE on March 12, 2018 was $48.38 per share.

We are an “emerging growth company” under applicable Securities and Exchange Commission rules and are subject to reduced public company reporting requirements.

Investing in our Class A common stock involves risks. See “Risk Factors” beginning on page S-6.

The Securities and Exchange Commission and state securities regulators have not approved or disapproved these securities, or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the shares of Class A common stock to purchasers on or about March 15, 2018.

RISK FACTORS

Investing in our Class A common stock involves a high degree of risk. You should carefully consider the following risks and all other information contained in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference herein and therein, including our financial statements and the related notes thereto, before investing in our Class A common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, also may become important factors that affect us. If any of the following risks materialize, our business, financial condition and results of operations could be materially adversely affected. In that case, the trading price of our Class A common stock could decline, and you may lose some or all of your investment.

Risks Related to Recent Changes in Tax Laws

Recent U.S. tax legislation may materially adversely affect our financial condition, results of operations and cash flows.

Recently enacted U.S. tax legislation has significantly changed the U.S. federal income taxation of U.S. corporations, including by reducing the U.S. corporate income tax rate, limiting interest deductions, permitting immediate expensing of certain capital expenditures, adopting elements of a territorial tax system, imposing a one-time transition tax (or “repatriation tax”) on all undistributed earnings and profits of certain U.S.-owned foreign corporations, revising the rules governing net operating losses and the rules governing foreign tax credits, and introducing new anti-base erosion provisions. Many of these changes are effective immediately, without any transition periods or grandfathering for existing transactions. ASC 740 requires all companies to reflect the effects of the new law in financial statements of the period in which the law was enacted. Accordingly, we reduced the statutory rate that applies to our year-to-date earnings, remeasured our deferred tax assets and liabilities based on the new rate, and recorded a one-time deemed repatriation tax (a “toll charge”) on our foreign earnings in our reporting period ended December 31, 2017. The impacts of the legislation, including both the adjustment to the deferred tax accounts and the toll charge, are our best estimates based on the information that is available at the time of these financial statements and may change as additional information becomes available. Adjustments to deferred tax expense could arise if the actual timing of future deferred tax reversals and originations differs from current estimates. As for the toll charge, the calculation involves a number of variables and assumptions, including state tax impacts, which will continue to be refined by us from the fourth quarter through the filing date of our federal and state tax returns. In addition, the legislation is unclear in many respects and could be subject to potential amendments and technical corrections, as well as interpretations and implementing regulations by the Treasury and Internal Revenue Service (“IRS”), any of which could lessen or increase certain adverse impacts of the legislation. Furthermore, it is unclear how these U.S. federal income tax changes will affect state and local taxation, which often uses federal taxable income as a starting point for computing state and local tax liabilities. If an adjustment is required, it will be reflected as a discrete expense or benefit in the quarter that it is identified, as allowed by SEC Staff Accounting Bulletin No. 118. We urge our investors to consult with their legal and tax advisors with respect to such legislation and the potential tax consequences of investing in our Class A common stock.

Risks Related to Our Class A Common Stock and this Offering

The dual class structure of our common stock and the existing ownership of our Class B common stock by ORIX USA and the HL Holders through the HL Voting Trust have the effect of concentrating voting control with ORIX USA and the HL Voting Trust for the foreseeable future, which will limit your ability to influence corporate matters. We are controlled by ORIX USA and the HL Voting Trust, whose interests may differ from those of our public stockholders.

Each share of our Class B common stock is entitled to ten votes per share, and each share of our Class A common stock, which is the stock we and the selling stockholders are offering in this offering, is entitled to one vote per share. Given the greater number of votes per share attributed to our Class B common stock, following this offering and the settlement of the forward repurchase, ORIX USA and the HL Holders through the HL Voting Trust, which each hold shares of Class B common stock, will collectively beneficially own shares of Class A common stock and Class B common stock representing approximately 54.2% of the economic interest and 92.1% of the voting power of our outstanding capital stock. ORIX USA and the HL Voting Trust will, for the foreseeable future, have significant influence over our corporate management and affairs, and will be able to control virtually all matters requiring stockholder approval. ORIX USA and the HL Voting Trust are collectively able to, subject to applicable law and to the voting arrangements described under the section “Corporate Governance — Director Nomination and Removal Process” in our definitive proxy statement filed with the Securities and Exchange Commission on July 26, 2017 and in Part II, Item 5 of our quarterly report on Form 10-Q for the quarter ended September 30, 2017 filed with the Securities and Exchange Commission, elect a majority of the members of our board of directors and control actions to be taken by us and our board of directors, including amendments to our amended and restated certificate of incorporation and bylaws and approval of significant corporate transactions, including mergers and sales of substantially all of our assets. Such directors have the authority, subject to the terms of our indebtedness and applicable rules and regulations, to issue additional stock, implement stock repurchase programs, declare dividends and make other decisions.

The continued concentrated control of the HL Voting Trust and ORIX USA will limit your ability to influence corporate matters for the foreseeable future and may materially adversely affect the market price of our Class A common stock. It is possible that the interests of ORIX USA and the HL Voting Trust may in some circumstances conflict with our interests and the interests of our other stockholders, including you. For example, ORIX USA and the HL Voting Trust may have different tax positions or other differing incentives from other stockholders that could influence their decisions regarding whether and when to cause us to dispose of assets, incur new or refinance existing indebtedness or take other actions. Additionally, the holders of our Class B common stock may cause us to make strategic decisions or pursue acquisitions that could involve risks to you or may not be aligned with your interests.

The holders of our Class B common stock are also entitled to a separate vote in the event we seek to amend our amended and restated certificate of incorporation to increase or decrease the par value of a class of our common stock or alter or change the powers, preferences or special rights of the Class B common stock in a manner that affects its holders adversely. Future transfers by holders of Class B common stock will generally result in those shares converting on a one-for-one basis to Class A common stock, which will have the effect, over time, of increasing the relative voting power of those holders of Class B common stock who retain their shares in the long-term.

The trading price of our Class A common stock may be affected by limited trading volume and may fluctuate significantly, which may affect stockholders’ ability to sell shares of our Class A common stock.

There has been a limited public market for our Class A common stock and a more active trading market for our Class A common stock may not develop. A substantial majority of our common stock is Class B common stock that is not freely tradeable unless and until converted into Class A common stock. Following this offering, there can be no assurance that the selling stockholders will convert any additional shares of their existing Class B common stock into Class A common stock and sell any such shares, or that the HL Holders will convert any

S-7

additional shares of Class B common stock into shares of Class A common stock and sell such shares in the future. These factors may result in different prices for our Class A common stock than might otherwise be obtained in a more liquid market and could also result in a significant spread between the bid and ask prices for our Class A common stock. In addition, without a larger public float, our Class A common stock may be less liquid than the stock of companies with broader public ownership, and, as a result, the trading prices of our Class A common stock may be more volatile. In the absence of an active public trading market, an investor may be unable to liquidate its investment in our Class A common stock. Trading of a relatively small volume of our common stock may have a greater impact on the trading price of our Class A common stock than would be the case if our public float were larger. We cannot predict the prices at which our Class A common stock will trade in the future, if at all.

We are a “controlled company” within the meaning of the New York Stock Exchange listing standards and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

We are a “controlled company” within the meaning of the corporate governance standards of the New York Stock Exchange. Under these rules, a listed company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements, including the requirement that a majority of the board of directors consist of independent directors, the requirement that we have a nominating and corporate governance committee that is composed entirely of independent directors and the requirement that we have a compensation committee that is composed entirely of independent directors. We intend to continue to rely on some or all of these exemptions. As a result, we do not and, for the foreseeable future, will not have a majority of independent directors and our compensation and nominating and corporate governance committees will not consist entirely of independent directors. Accordingly, you will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the New York Stock Exchange.

The trading price of our Class A common stock may be volatile or may decline regardless of our operating performance and you may not be able to resell your shares at or above the offering price.

The market price of our Class A common stock may fluctuate significantly in response to a number of factors, most of which we cannot control, including:

S-8

Volatility in the market price of our common stock may prevent investors from being able to sell their Class A common stock at or above the offering price. As a result, you may suffer a loss on your investment. In addition, stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies in our industry. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were involved in securities litigation, we could incur substantial costs and our resources and the attention of management could be diverted from our business.

Our share price may decline due to the large number of shares eligible for future sale.

The market price of our Class A common stock could decline as a result of sales of a large number of shares of Class A common stock in the market after this offering or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Shares of common stock held by HL Holders indirectly through the HL Voting Trust are subject to lock-up agreements that restrict their ability to transfer shares of our capital stock until at least August 18, 2018, subject to acceleration in certain circumstances. After this period, shares of common stock held by HL Holders indirectly through the HL Voting Trust will become transferable in three equal installments on each of August 18, 2018, 2019 and 2020; provided that the shares sold by the selling stockholders in this offering will reduce the number of shares that become transferable on August 18, 2018. In addition, shares of our common stock held by managing directors and certain senior corporate officers of the Company whose employment with the Company or a subsidiary thereof terminates (other than due to a death or disability) before August 18, 2018 will be subject to transfer restrictions until August 2022. As of March 8, 2018, 27,498,840 shares of our common stock were held through the HL Voting Trust and subject to the lock-up agreements described above.

As of the date of this prospectus supplement, subject to the restrictions under the lock-up agreements described above and subject to certain restrictions under the Securities Act of 1933, as amended (the “Securities Act”), the 39,209,171 shares of our Class A common stock issuable upon conversion of outstanding Class B common stock and the 24,250 vested shares of Class A common stock issued under our 2016 Incentive Award Plan to our non-employee directors are eligible for sale. Stockholders who are subject to any of the lock-up agreements described above may be permitted to sell shares prior to the expiration of the applicable lock-up agreement in certain circumstances, including as the result of the waiver or termination of such lock-up agreement.

S-9

While we currently pay a quarterly cash dividend to our stockholders, we may change our dividend policy at any time and we may not continue to declare cash dividends.

Although we currently pay a quarterly cash dividend to our stockholders, we have no obligation to do so, and our dividend policy may change at any time. Returns on stockholders’ investments will primarily depend on the appreciation, if any, in the price of our Class A common stock. The amount and timing of dividends, if any, are subject to capital availability and periodic determinations by our board of directors that cash dividends are in the best interest of our stockholders and are in compliance with all applicable laws and any other contractual agreements limiting our ability to pay dividends. Under our Revolving Credit Facility with Bank of America, N.A., we are restricted from paying cash dividends in certain circumstances, and we expect these restrictions to continue in the future. Our ability to pay dividends may also be restricted by the terms of any future credit agreement or any future debt or preferred equity securities of ours or of our subsidiaries. Future dividends, including their timing and amount, may be affected by, among other factors: general economic and business conditions; our financial condition and operating results; our available cash and current anticipated cash needs; capital requirements; contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our stockholders; and such other factors as our board of directors may deem relevant.

Our dividend payments may change from time to time, and we may not continue to declare dividends in any particular amounts or at all. The reduction in or elimination of our dividend payments could have a negative effect on our stock price.

Lastly, the record date for our previously-announced regular quarterly cash dividend payable on March 15, 2018 is Friday, March 2, 2018. This offering will close after such record date and, as a result, purchasers of the shares in this offering will not be entitled to receive the dividend payable on March 15, 2018 in respect of such shares purchased in this offering.

If securities analysts do not publish research or reports about our business or if they downgrade our Company or our sector, the price of our Class A common stock could decline.

The trading market for our Class A common stock depends in part on the research and reports that industry or financial analysts publish about us or our business. We do not control these analysts. Furthermore, if one or more of the analysts who do cover us downgrades our Company or our industry, or the stock of any of our competitors, the price of our Class A common stock could decline. If one or more of these analysts ceases coverage of our Company, we could lose visibility in the market, which in turn could cause the price of our Class A common stock to decline.

Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make our Class A common stock less attractive to investors. Loss of “emerging growth company” status will increase our legal and financial costs.

The JOBS Act provides that, so long as a company qualifies as an “emerging growth company,” it will, among other things:

S-10

We currently take advantage of each of the exemptions described above. We have irrevocably elected not to take advantage of the extension of time to comply with new or revised financial accounting standards available under Section 107(b) of the JOBS Act. We will be an emerging growth company until March 31, 2018. We cannot predict if investors will find our Class A common stock less attractive if we continue to elect to rely on these exemptions, or if taking advantage of these exemptions would result in less active trading or more volatility in the price of our Class A common stock.

The market value of our common stock held by non-affiliates as of June 30, 2017, was approximately $762 million and exceeded $700 million as of December 31, 2017. As a result, we will no longer be an emerging growth company as of March 31, 2018. When the emerging growth company exemptions cease to apply to us, compliance with additional public company requirements will significantly increase our legal and financial costs and place additional significant demands on our management.

Our anti-takeover provisions could prevent or delay a change in control of our Company, even if such change in control would be beneficial to our stockholders.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law could discourage, delay or prevent a merger, acquisition or other change in control of our Company, even if such change in control would be beneficial to our stockholders. Certain provisions of our amended and restated certificate of incorporation and our amended and restated bylaws that could prevent or delay a change in control of our Company include:

These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and cause us to take other corporate actions you desire. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team.

In addition, the General Corporation Law of the State of Delaware (the “DGCL”), to which we are subject, prohibits us, except under specified circumstances, from engaging in any mergers, significant sales of stock or

S-11

assets or business combinations with any stockholder or group of stockholders who owns at least 15% of our common stock.

We may issue shares of preferred stock in the future, which could make it difficult for another company to acquire us or could otherwise adversely affect holders of our Class A common stock, which could depress the price of our Class A common stock.

Our amended and restated certificate of incorporation authorizes us to issue one or more series of preferred stock. Our board of directors has the authority to determine the preferences, limitations and relative rights of the shares of preferred stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our stockholders. Our preferred stock could be issued with voting, liquidation, dividend and other rights superior to the rights of our Class A common stock. The potential issuance of preferred stock may delay or prevent a change in control of us, discourage bids for our Class A common stock at a premium to the market price, and materially and adversely affect the market price and the voting and other rights of the holders of our Class A common stock.

The provision of our amended and restated certificate of incorporation requiring exclusive venue in the Court of Chancery in the State of Delaware for certain types of lawsuits may have the effect of discouraging lawsuits against our directors, officers and stockholders.

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction in the Court of Chancery of the State of Delaware or (iv) any action asserting a claim governed by the internal affairs doctrine will have to be brought only in the Court of Chancery in the State of Delaware, unless we agree otherwise. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors, officers and stockholders.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement contains forward-looking statements. All statements other than statements of historical facts contained in this prospectus supplement may be forward-looking statements. Statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions.

Forward-looking statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. We believe that these factors include, but are not limited to, the following:

S-13

We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements.

These forward-looking statements speak only as of the date of this prospectus supplement. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this prospectus supplement after we distribute this prospectus supplement, whether as a result of any new information, future events or otherwise.

S-14

USE OF PROCEEDS

We estimate that the net proceeds to be received by us from this offering, after deducting any underwriting discounts and commissions, will be approximately $93.5 million.

We intend to use such net proceeds to acquire 2,000,000 shares of our Class B common stock from ORIX USA at a purchase price per share equal to the public offering price in this offering less underwriting discounts and commissions pursuant to a forward share purchase agreement. See “Description of the Forward Share Purchase Agreement” for additional information.

Because the forward share purchase agreement requires delivery of a fixed number of shares for a fixed amount of cash at settlement, the forward repurchase will be accounted for as a financed purchase of treasury stock and the shares subject to the forward share purchase agreement will not be included in our basic or diluted earnings per share in conformity with U.S. GAAP.

We will not receive any net proceeds from the sale of shares of our Class A common stock by the selling stockholders. We are conducting this offering to facilitate organized liquidity in our Class A common stock and to increase the public float of our Class A common stock.

S-15

DESCRIPTION OF THE FORWARD SHARE PURCHASE AGREEMENT

On January 26, 2018, in connection with, and prior to, the commencement of this offering, we entered into a forward share purchase agreement with ORIX USA, pursuant to which we agreed to repurchase from ORIX USA on April 5, 2018 the number of shares of our Class B common stock equal to the number of shares of Class A common stock sold by us in this offering for a purchase price per share equal to the public offering price in this offering less underwriting discounts and commissions. The effectiveness of the forward share purchase agreement is conditioned only upon the completion of this offering. The rights and obligations of each party under the forward share purchase agreement are non-transferrable without the consent of the non-transferring party. Upon the pricing of this offering, we and ORIX USA will enter into an escrow agreement, pursuant to which we will deposit into escrow the net proceeds received by us from this offering (the “Escrow Amount”) and ORIX USA will deposit into escrow the number of shares of Class B common stock to be acquired by us (the “Escrow Shares”).

If our board of directors pays a dividend on our common stock during the period between the closing of this offering and the settlement of the forward repurchase on April 5, 2018, ORIX USA will be entitled to receive any such dividend payable on the shares of Class B common stock subject to the forward share purchase agreement. If the record date for any such dividend occurs between the closing of this offering and the settlement of the forward purchase on April 5, 2018, then the purchase price per share under the forward repurchase will be reduced by the per share amount of any such dividend. In that case, the Escrow Amount will also be reduced by the amount of any such dividend, without reduction for any withholding or other taxes (the “Dividend Amount”), and each such Dividend Amount will be released to us from the escrow. Prior to April 5, 2018, ORIX USA will retain all voting rights in respect of, and will receive any dividends payable on, such Escrow Shares. During such period, the Escrow Shares will continue to count towards ORIX USA’s ownership thresholds under the Stockholders’ Agreement, dated August 18, 2015, among us, ORIX USA and the HL Voting Trust. As a result of the mechanics described in this paragraph, ORIX USA will be entitled to the regular quarterly cash dividend of $0.20 per share to be paid on March 15, 2018 in respect of the shares of Class B common stock subject to the forward share purchase agreement, but such dividend will not reduce the purchase price per share under the forward share purchase agreement.

On April 5, 2018, we will receive from escrow the Escrow Shares and ORIX USA will receive the Escrow Amount, as reduced by any Dividend Amounts, if applicable. We intend to retire the Escrow Shares after the settlement of the forward repurchase. Because the forward share purchase agreement requires delivery of a fixed number of shares for a fixed amount of cash at settlement, the forward repurchase will be accounted for as a financed purchase of treasury stock and the shares subject to the forward share purchase agreement will not be included in our basic or diluted earnings per share in conformity with U.S. GAAP.

The forward share purchase agreement is a separate transaction entered into by us with ORIX USA, is not part of the terms of the Class A common stock and will not change the holders’ rights with respect to the Class A common stock. As a holder of Class A common stock, you will not have any rights with respect to the forward share purchase agreement.

S-16

Set forth below is information regarding ORIX USA’s ownership of our common stock, both prior to this offering and following this offering and the forward repurchase. The percentages of beneficial ownership prior to and following this offering and the forward repurchase set forth below are based on 26,602,405 shares of Class A common stock and 39,209,171 shares of Class B common stock outstanding as of March 8, 2018, and assume (i) the sale of all shares of Class A common stock offered by the selling stockholders pursuant to this prospectus supplement and (ii) the settlement of the forward repurchase, which has the effect of excluding any shares to be sold by the Company in this offering, since such additional shares will be offset in full by the shares repurchased from ORIX USA in the forward repurchase.

S-17

SELLING STOCKHOLDERS

The selling stockholders named below are offering to sell an aggregate of 2,000,000 shares of Class A common stock, which are issuable upon conversion on a one-for-one basis of shares of Class B common stock currently owned by the selling stockholders.

The percentages of beneficial ownership prior to and following this offering and the forward repurchase set forth below are based on a total of 26,602,405 shares of Class A common stock and 39,209,171 shares of Class B common stock outstanding as of March 8, 2018, and assume (i) the sale of all shares of Class A common stock offered by the selling stockholders pursuant to this prospectus supplement and (ii) the settlement of the forward repurchase, which has the effect of excluding the shares to be sold by the Company in this offering, since such additional shares will be offset in full by the shares repurchased from ORIX USA in the forward repurchase.

Beneficial ownership is determined in accordance with the rules of the SEC.

SUPPLEMENTAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR NON-UNITED STATES HOLDERS OF CLASS A COMMON STOCK

This discussion is a supplement to, and is intended to be read together with, the discussion under the heading “Material United States Federal Income Tax Considerations for Non-United States Holders of Class A Common Stock” contained in the accompanying prospectus. This summary is for general information only and is not tax advice.

The discussion under the heading “Material United States Federal Income Tax Considerations for Non-United States Holders of Class A Common Stock” in the accompanying prospectus is hereby supplemented to delete “and” at the end of the eleventh bullet of the second paragraph, insert “and” at the end of the twelfth bullet of the second paragraph and add the following bullet as the thirteenth bullet of the second paragraph:

S-21

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement among us, the selling stockholders and the underwriters named below, we and the selling stockholders, severally and not jointly, have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase, at the offering price less any underwriting discounts and commissions set forth on the cover page of this prospectus supplement, from us and the selling stockholders, the number of shares of Class A common stock set forth opposite its name below.

The underwriters are collectively referred to as the “underwriters”. To the extent there is one underwriter, “underwriters” refers to the underwriter listed in the table above. The underwriters are committed to purchase all the shares of Class A common stock offered by us and the selling stockholders if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the shares of Class A common stock directly to the public at the offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $0.15 per share. After the initial offering of the shares of Class A common stock, the offering price and other selling terms may be changed by the underwriters.

We and the selling stockholders have agreed to indemnify the several underwriters and their controlling persons against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

Underwriting Discounts and Expenses

The underwriting fee is equal to the public offering price per share of Class A common stock less the amount paid by the underwriters to us per share of Class A common stock. The underwriting fee is $0.50 per share. The offering of the shares of Class A common stock by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses associated with this offering will be approximately $750,000. We have agreed to reimburse the underwriters for certain expenses, including up to an aggregate of $10,000 in connection with the clearance of this offering with FINRA. Such reimbursement is deemed to be underwriting compensation by FINRA.

S-22

Lock-up

We have agreed that we will not:

Our directors, executive officers, ORIX USA and the selling stockholders have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons or entities, with limited exceptions, for a period of 60 days after the date of this prospectus supplement, may not, without the prior written consent of the underwriters:

The foregoing restrictions do not apply to the sale of Class A common stock by the selling stockholders in this offering or the sale of Class B common stock by ORIX USA in the forward repurchase.

Listing

Our Class A common stock is listed on the New York Stock Exchange under the symbol “HLI.”

Price Stabilization, Short Positions and Penalty Bids

In connection with the offering, the underwriters may purchase and sell our Class A common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of

S-23

shares than they are required to purchase in the offering. The underwriters must close out any short position by purchasing shares in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our Class A common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of Class A common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.

None of the underwriters, the selling stockholders or us make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, none of the underwriters, the selling stockholders or us make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full-service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing, and brokerage activities. Certain of the underwriters and their affiliates have provided in the past to us, the selling stockholders and our other affiliates, and may provide from time to time in the future, certain commercial banking, financial advisory, investment banking and other services in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

Selling Restrictions

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered pursuant to this prospectus supplement and the accompanying prospectus in any jurisdiction where action for that purpose is required. The securities offered pursuant to this prospectus supplement and the accompanying prospectus may not be offered or sold, directly or indirectly, nor may this prospectus supplement and the accompanying prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus supplement and the accompanying prospectus come are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus supplement. This prospectus supplement and the accompanying prospectus do not constitute an offer to sell or a solicitation of an offer to buy any securities offered pursuant to this prospectus supplement and the accompanying prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our certificate of incorporation, which has been publicly filed with the SEC. See “Where You Can Find More Information; Incorporation by Reference.”

General

Our authorized capital stock consists of 2,000,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share.

Our common stock is divided into two classes, Class A common stock and Class B common stock. Our authorized Class A common stock consists of 1,000,000,000 shares and our authorized Class B common stock consists of 1,000,000,000 shares.

The following description of our capital stock and provisions of our amended and restated certificate of incorporation and amended and restated bylaws are summaries and are qualified by reference to the amended and restated certificate of incorporation and amended and restated bylaws, which are filed as exhibits to the registration statements of which this prospectus forms a part, and by applicable law.

Class A Common Stock and Class B Common Stock

As of October 16, 2017, there were 24,667,070 shares of our Class A common stock outstanding and 41,999,807 shares of Class B common stock outstanding.

Voting Rights

Holders of our Class A common stock and Class B common stock have identical rights, provided that, except as otherwise described below with respect to the right to vote on any amendment to our amended and restated certificate of incorporation relating to any series of preferred stock or as required by applicable law, on any matter that is submitted to a vote of our stockholders, holders of our Class A common stock are entitled to one vote per share of Class A common stock and holders of our Class B common stock are entitled to ten votes per share of Class B common stock. Holders of shares of Class A common stock and Class B common stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, except as otherwise expressly provided in our amended and restated certificate of incorporation or required by applicable law.

Under our amended and restated certificate of incorporation, we may not increase or decrease the authorized number of shares of Class A common stock or Class B common stock without the affirmative vote of the holders of a majority of the voting power of the outstanding shares of our capital stock entitled to vote, voting together as a single class. Under our amended and restated certificate of incorporation, holders of our Class A common stock and Class B common stock are not entitled to vote on any amendment to our amended and restated certificate of incorporation that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to our amended and restated certificate of incorporation or pursuant to the Delaware General Corporation Law (the “DGCL”).

We have not provided for cumulative voting for the election of directors in our amended and restated certificate of incorporation.

Economic Rights

Except as otherwise expressly provided in our amended and restated certificate of incorporation or required by applicable law, shares of Class A common stock and Class B common stock have the same rights and privileges and rank equally, share ratably and be identical in all respects as to all matters, including, without limitation, those described below.

Dividends. Any dividends or distributions paid or payable to the holders of shares of Class A common stock and Class B common stock shall be paid equally, identically and ratably, on a per share basis, unless different treatment of the shares of each such class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class; provided, however, that if a dividend or distribution is paid in the form of Class A common stock or Class B common stock (or rights to acquire shares of Class A common stock or Class B common stock), then the holders of the Class A common stock will receive Class A common stock (or rights to acquire shares of Class A common stock) and holders of Class B common stock will receive Class B common stock (or rights to acquire shares of Class B common stock) with holders of Class A common stock and Class B common stock receiving an identical number of shares of Class A common stock or Class B common stock (or rights to acquire such stock, as the case may be).

Liquidation. In the event of our dissolution, liquidation or winding-up of our affairs, whether voluntary or involuntary, after payment or provision for payment of our debts and other liabilities and after making provision for the entitlements of holders of any series of preferred stock, our remaining assets and funds, if any, shall be divided among and paid ratably to the holders of the shares of Class A common stock and Class B common stock, treated as a single class, unless different treatment of the shares of each such class is approved by the affirmative votes of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class.

Subdivisions, Combinations and Reclassifications. If we subdivide, combine or reclassify in any manner outstanding shares of Class A common stock or Class B common stock, then the outstanding shares of all common stock will be subdivided, combined or reclassified in the same proportion and manner, unless different treatment of the shares of each such class is approved by the affirmative votes of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class.

Change of Control Transaction. In connection with any change of control transaction (as defined in our amended and restated certificate of incorporation), the holders of Class A common stock and Class B common stock will be treated equally, identically and ratably, on a per share basis, with respect to any consideration into which such shares are converted or any consideration paid or otherwise distributed to stockholders, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class.

Conversion

Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock. In addition, each share of Class B common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value and whether voluntary or involuntary or by operation of law, except for certain transfers described in our amended and restated certificate of incorporation. In addition, upon the date on which (x) the aggregate outstanding shares of common stock owned by (i) ORIX USA, (ii) the HL Voting Trust and (iii) the beneficiaries of the HL Voting Trust or certain of their transferees, together with (y) the outstanding shares of our common stock (A) received by a holder of our common stock in connection with the grant, vesting and/or payment of an equity compensatory award and (B) with respect to which such holder has given the right to vote, pursuant to an irrevocable proxy, to the person or persons as may be designated by us from time to time, collectively represent less than 20% of the then

8

aggregate outstanding shares of common stock, or on a date specified by the holders of at least 66 ²⁄₃% of the outstanding shares of Class B common stock (the “Final Conversion Date”), all outstanding shares of Class B common stock shall convert automatically into Class A common stock.

Transfer Agent and Registrar

The transfer agent and registrar for our Class A common stock is Computershare Trust Company, N.A.

Listing

Our Class A common stock is listed on the New York Stock Exchange under the symbol “HLI.”

Preferred Stock

Under the terms of our amended and restated certificate of incorporation, our board of directors is authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, powers, privileges, preferences and relative, participating, optional or other special rights, and any qualifications, limitations or restrictions, of each series of preferred stock. Subject to the rights of the holders of any series of preferred stock, the number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all the outstanding shares of stock of the Company entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of the preferred stock voting separately as a class shall be required therefor.

The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock. There are currently no shares of preferred stock outstanding.

Registration Rights

We have entered into Registration Rights Agreements with each of ORIX USA and the HL Holders pursuant to which these holders can demand that we file a registration statement relating to shares of our common stock, including shares of our Class A common stock issuable upon conversion of the shares of our Class B Common Stock, which common stock we refer to as registrable shares, and can request that their registrable shares be covered by a registration statement that we are otherwise filing. In the case of the HL Holders, these rights are subject to the lock-up provisions discussed in our Form 10-K under “Certain Relationships and Related Person Transactions—Agreements with the HL Holders—Lock-Up Agreements.”

Demand Registration Rights. Under the terms of each of the Registration Rights Agreements, the holders of registrable shares entitled to demand registration rights may request that we register all or a portion of their registrable shares for sale under the Securities Act. We will effect the registration as requested unless, in the good faith and reasonable judgment of our board of directors, such registration should be delayed. We may be required to effect three of these registrations per year. In addition, at times when we are eligible for the use of Form S-3, or any successor form, holders of registrable shares entitled to demand registration rights may make unlimited requests that we register all or a portion of their registrable shares for sale under the Securities Act on Form S-3, or any successor form.

9

Incidental Registration Rights. In addition, if at any time we register any shares of our Class A common stock, the holders of all registrable shares are entitled to notice of the registration and to have all or a portion of their registrable shares included in the registration. Pursuant to each Registration Rights Agreement, if either ORIX USA or the HL Holders intends to sell shares of Class A common stock in an underwritten offering, the other party has a right to participate in such offering under specified conditions.

Other Provisions. In the event that any registration in which the holders of registrable shares participate pursuant to either of our Registration Rights Agreements is an underwritten public offering, the number of registrable shares to be included may, in specified circumstances, be limited due to market conditions.

We will pay all registration expenses related to any demand or incidental registration, other than underwriting discounts, selling commissions and transfer taxes. Our Registration Rights Agreements contain cross- indemnification provisions, pursuant to which we are obligated to indemnify the selling stockholders in the event of material misstatements or omissions in the registration statement attributable to us, and they are obligated to indemnify us for material misstatements or omissions in the registration statement attributable to them.

Exclusive Venue

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware or (iv) any action asserting a claim governed by the internal affairs doctrine will have to be brought only in the Court of Chancery in the State of Delaware, unless we agree otherwise. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Anti-Takeover Provisions

We are not governed by Section 203 of the DGCL (“Section 203”), and the restrictions contained in Section 203 will not apply to us, until the moment in time immediately following the time at which both of the following conditions exist (if ever): (i) Section 203 by its terms would, but for the provisions of our amended and restated certificate of incorporation, apply to us; and (ii) the Final Conversion Date has occurred, and we will thereafter be governed by Section 203 if and for so long as Section 203 by its terms shall apply to us. Subject to certain exceptions, Section 203 prevents a publicly-held Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person will be an “interested stockholder” subject to any such prohibition on engaging in business combinations with us.

Classified Board of Directors and Removal of Directors

Our amended and restated certificate of incorporation and our amended and restated bylaws provide for the division of our board of directors into three classes, with the classes as nearly equal in number as possible and each class serving three-year staggered terms. Our amended and restated certificate of incorporation and our amended and restated bylaws also provide that, from and after the Final Conversion Date, a director may be removed only for cause and only by the affirmative vote of the holders of at least 66 ²⁄₃% of the votes that all of our stockholders would be entitled to cast in an annual election of directors. Additional provisions with regard

10

to removal of directors are included in our Stockholders’ Agreement. Subject to any rights of the holders of any series of preferred stock to elect directors, any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. The limitations on the removal of directors and filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of our Company.

Super-Majority Voting

The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our amended and restated bylaws may be amended or repealed by a majority vote of our board of directors or the affirmative vote of the holders of at least 66 ²⁄₃% of the votes that all of our stockholders would be entitled to cast in an annual election of directors. In addition, the affirmative vote of the holders of at least 66 ²⁄₃% of the votes of the then-outstanding shares of our capital stock, which all our stockholders would be entitled to cast in an election of directors, voting together as a single class, is required to amend or repeal or to adopt any provisions inconsistent with any of the provisions of our amended and restated certificate of incorporation described in this paragraph and under “—Classified Board of Directors and Removal of Directors” above.

Stockholder Action by Written Consent

Pursuant to Section 228 of the DGCL, any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted, unless our amended and restated certificate of incorporation provides otherwise. From and after the Final Conversion Date, any action required or permitted to be taken by the stockholders of the Company must be effected at a duly called annual or special meeting of stockholders of the Company and may not be effected by any consent in writing by such stockholders in lieu of a meeting.

Special Meeting of Stockholders

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that, except as otherwise required by law, special meetings of our stockholders can only be called by our board of directors pursuant to a resolution adopted by the majority of our board, our chairman of the board (or in the event of co-chairmen, either chairman), our chief executive officer, our president or either of our co-presidents (in the event there is no chief executive officer).

Authorized But Unissued Shares

The authorized but unissued shares of our common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the NYSE. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

SELLING SECURITYHOLDERS

Information about selling securityholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the SEC under the Exchange Act that are incorporated by reference.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR NON-UNITED STATES HOLDERS OF CLASS A COMMON STOCK

The following discussion is a summary of the material United States federal income tax consequences to Non-United States Holders (as defined below) of the purchase, ownership and disposition of our Class A common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other United States federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-United States tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-United States Holder of our Class A common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our Class A common stock.

This discussion is limited to Non-United States Holders that hold our Class A common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all United States federal income tax consequences relevant to a Non-United States Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-United States Holders subject to special rules, including, without limitation:

If an entity treated as a partnership for United States federal income tax purposes holds our Class A common stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our Class A common stock and the partners in such partnerships should consult their tax advisors regarding the United States federal income tax consequences to them.

13

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE UNITED STATES FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-UNITED STATES TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-United States Holder

For purposes of this discussion, a “Non-United States Holder” is any beneficial owner of our Class A common stock that is neither a “United States person” nor an entity treated as a partnership for United States federal income tax purposes. A United States person is any person that, for United States federal income tax purposes, is or is treated as any of the following:

Distributions

If we make distributions of cash or property on our Class A common stock, such distributions will constitute dividends for United States federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under United States federal income tax principles. Amounts not treated as dividends for United States federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-United States Holder’s adjusted tax basis in its Class A common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “—Sale or Other Taxable Disposition.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-United States Holder of our Class A common stock will be subject to United States federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-United States Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). If a Non-United States Holder holds the stock through a financial institution or other intermediary, the Non-United States Holder will be required to provide appropriate documentation to the intermediary, which then will be required to provide certification to the applicable withholding agent, either directly or through other intermediaries. A Non-United States Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-United States Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-United States Holder are effectively connected with the Non-United States Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-United States Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-United States Holder will be exempt from the United States federal

14

withholding tax described above. To claim the exemption, the Non-United States Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-United States Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to United States federal income tax on a net income basis at the regular graduated rates. A Non-United States Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-United States Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

A Non-United States Holder will not be subject to United States federal income tax on any gain realized upon the sale or other taxable disposition of Class A our common stock unless:

Gain described in the first bullet point above generally will be subject to United States federal income tax on a net income basis at the regular graduated rates. A Non-United States Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items. Gain described in the second bullet point above will be subject to United States federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by United States source capital losses of the Non-United States Holder (even though the individual is not considered a resident of the United States), provided the Non-United States Holder has timely filed United States federal income tax returns with respect to such losses. With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC.

Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-United States real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-United States Holder of our Class A common stock will not be subject to United States federal income tax if our Class A common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-United States Holder owned, actually and constructively, 5% or less of our Class A common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-United States Holder’s holding period.

Non-United States Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our Class A common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States

15

person and the holder either certifies its non-United States status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our Class A common stock paid to the Non-United States Holder, regardless of whether any tax was actually withheld.

In addition, proceeds of the sale or other taxable disposition of our Class A common stock within the United States or conducted through certain United States-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A common stock conducted through a non-United States office of a non-United States broker generally will not be subject to backup withholding or information reporting. Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-United States Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-United States Holder’s United States federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-United States financial institutions and certain other non-United States entities. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our Class A common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the United States Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A common stock and will apply to payments of gross proceeds from the sale or other disposition of such stock on or after January 1, 2019.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A common stock.
