## Exhibit 99.1

**EXHIBIT 99.1**

**CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS**

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership, and disposition of our 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 U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local, or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. 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-U.S. Holder. 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 Common Stock.

This discussion is limited to Non-U.S. Holders that hold our 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 U.S. federal income tax consequences relevant to a Non-U.S. Holder's particular circumstances, including the impact of the Medicare contribution tax on net investment income and any alternative minimum tax. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;· persons that actually or constructively own more than 5% of our Common Stock (except to the extent specifically
set forth below);

&nbsp;&nbsp;&nbsp;&nbsp;· U.S. expatriates and former citizens or long-term residents of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;· persons holding our Common Stock as part of a hedge, straddle, or other risk reduction strategy or as
part of a conversion transaction or other integrated investment;

&nbsp;&nbsp;&nbsp;&nbsp;· banks, insurance companies, and other financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;· brokers, dealers, or traders in securities;

&nbsp;&nbsp;&nbsp;&nbsp;· "controlled foreign corporations," "foreign controlled foreign corporations,"
 "passive foreign investment companies," and corporations that accumulate earnings to avoid U.S. federal income tax;

&nbsp;&nbsp;&nbsp;&nbsp;· partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes
(and investors therein);

&nbsp;&nbsp;&nbsp;&nbsp;· tax-exempt organizations or governmental organizations;

&nbsp;&nbsp;&nbsp;&nbsp;· persons deemed to sell our Common Stock under the constructive sale provisions of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;· persons who hold or receive our Common Stock pursuant to the exercise of any employee stock option or
otherwise as compensation;

&nbsp;&nbsp;&nbsp;&nbsp;· tax-qualified retirement plans;

&nbsp;&nbsp;&nbsp;&nbsp;· "qualified foreign pension funds" as defined in Section 897(l)(2) of the Code and
entities all of the interests of which are held by qualified foreign pension funds; and

&nbsp;&nbsp;&nbsp;&nbsp;· persons subject to special tax accounting rules as a result of any item of gross income with respect
to our Common Stock being taken into account in an applicable financial statement.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our 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 whether certain determinations are made at the partnership or partner level. In addition, if we are or become a USRPHC (as defined below) it is unclear whether the 5% Test (as defined below) applies at the partnership or partner level, which could affect non-U.S. partners in partnerships that hold our Common Stock. Accordingly, partnerships holding our Common Stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

**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 U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.**

**Definition of a Non-U.S. Holder**

For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our Common Stock that is neither a "U.S. person" nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;· an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;· a corporation created or organized under the laws of the United States, any state thereof, or the District
of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;· an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;· a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or
more "United States persons" (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election
in effect to be treated as a United States person for U.S. federal income tax purposes.

**Distributions**

We currently do not anticipate declaring or paying dividends to holders of our Common Stock in the near term. However, if we do make distributions of cash or property on our Common Stock (other than certain pro rata distributions of our Common Stock), such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder's adjusted tax basis in its 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 and the discussion in the subsequent paragraph regarding our potential USRPHC status, dividends paid to a Non-U.S. Holder will be subject to U.S. 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-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. 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-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If we are considered a USRPHC at any time during the Testing Period (as defined below and treating the date of the distribution described below as the date of the disposition of our Common Stock for that purpose) and either the Non-U.S. Holder owns, actually or constructively, more than 5% of our Common Stock at any time during the Testing Period or our Common Stock ceases to be "regularly traded on an established securities market" (as discussed below under "—Sale or Other Taxable Disposition"), and if any distribution on our Common Stock exceeded our current and accumulated earnings and profits, the applicable withholding agent would satisfy any withholding requirements either by treating the entire distribution as a dividend that is subject to the withholding rules described in the preceding paragraph (and withhold at the rate described above, unless an income tax treaty applies, in which case the withholding agent would withhold at a minimum rate of 15% or such lower rate as may be specified by an applicable income tax treaty for distributions from a USRPHC), or by treating only the amount of the distribution reasonably estimated to be paid from our current or accumulated earnings and profits as a dividend, with the excess portion of the distribution possibly being subject to withholding at a rate of 15% or such lower rate as may be specified by an applicable income tax treaty as if such excess were the result of a sale of shares in a USRPHC.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. 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-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

**Sale or Other Taxable Disposition**

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Common Stock unless:

&nbsp;&nbsp;&nbsp;&nbsp;· the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business within
the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the
United States to which such gain is attributable);

&nbsp;&nbsp;&nbsp;&nbsp;· the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more
during the taxable year of the disposition and certain other requirements are met; or

&nbsp;&nbsp;&nbsp;&nbsp;· our Common Stock constitutes a U.S. real property interest ("USRPI") by reason of our status
as a U.S. real property holding corporation ("USRPHC") for U.S. federal income tax purposes at any applicable time within
the shorter of (i) the five year period preceding the Non-U.S. Holder's disposition of our Common Stock and (ii) the Non-U.S.
Holder's holding period for our Common Stock (such shorter time, the "Testing Period").

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. 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.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on gain realized upon the sale or other taxable disposition of our Common Stock, which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we may be or later become a USRPHC, but we have made no determination to that effect. Because the determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets (all as determined for U.S. federal income tax purposes), 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 of our Common Stock by a Non-U.S. Holder will not be subject to U.S. federal income tax (i.e., such Common Stock will not be a USRPI) if our Common Stock is "regularly traded," as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Common Stock (the "5% Test") throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder's holding period. If we are or were to become a USRPHC and our Common Stock is not or ceases to be regularly traded on an established securities market, a Non-U.S. Holder generally would be subject to U.S. federal income tax on a net income basis, as described above, on any gain realized from the sale or other taxable disposition of our Common Stock and a 15% withholding tax would apply to the gross proceeds from such disposition. Any amounts withheld may be refunded or credited against a Non-U.S. Holder's U.S. federal income tax liability, provided that the required information is timely provided to the IRS.

Non-U.S. 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 Common Stock will not be subject to backup withholding, provided the holder certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, or W-8ECI, and the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person, or the holder otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any distributions on our Common Stock paid to the Non-U.S. Holder, regardless of whether such distributions constitute dividends or whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Common Stock within the United States or conducted through certain U.S.-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 the holder is a United States person or the holder otherwise establishes an exemption. Proceeds of a disposition of our Common Stock conducted through a non-U.S. office of a non-U.S. 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-U.S. 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-U.S. Holder's U.S. 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-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, our 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 U.S. 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 Common Stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Common Stock.
