          stock under this shelf registration statement. This prospectus provides you with a general description of the common stock the selling stockholders may offer. We may provide a prospectus supplement containing specific information about the terms

      <div><br>
      </div>
      <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">An investment in our
            securities involves a high degree of risk. Before you decide whether to purchase any of our securities, in addition to the other information, documents or reports included in or incorporated by reference into this prospectus and any
            accompanying prospectus supplement or other offering materials, you should carefully consider the risk factors below and the risk factors in the section entitled &#8220;Risk Factors&#8221; in any prospectus supplement as well as in our most recent annual
            report on Form 10-K and any subsequent quarterly reports on Form 10-Q or current reports on Form 8-K, which are incorporated by reference into this prospectus and any prospectus supplement, as the same may be amended, supplemented or superseded
            from time to time by our filings under the Securities Exchange Act of 1934, as amended, or the Exchange Act. For more information please see the section entitled &#8220;Incorporation by Reference.&#8221; </font>The risks described in these documents are
          not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, legal, regulatory or other factors that could have material adverse effects on our future results.
          Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial
          condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below
          entitled &#8220;Forward-Looking Statements.&#8221;</font></div>

      <div><br>
      </div>
      <div style="text-align: left; margin-top: 0.4pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif; font-weight: bold; font-style: italic;">Sales of our common stock by the selling stockholders will dilute existing
          stockholders&#8217; proportionate voting power and their proportionate share of our earnings, and may cause our stock price to decline.</font></div>
      <div><br>
      </div>
      <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">The shares of our common stock being registered under the registration statement of which this prospectus is a part
          are held by majority-owned subsidiaries of ours, and pursuant to Delaware law we treat these shares of our common stock as treasury stock for voting purposes.&#160;&#160; For financial reporting purposes, only our proportional interest (<font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif; font-style: italic;">i.e.</font>, based on our 83% ownership interest of NL) in the shares of our common stock being registered under this registration statement is
          treated as treasury stock.&#160; As a result, our common shares outstanding for voting purposes differs from those outstanding for financial reporting purposes.</font></div>
      <div><br>
      </div>
      <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">As of March 8, 2019, we had
            339,185,449 shares of common stock outstanding for voting purposes, and such number of shares excludes the shares being registered under the registration statement of which this prospectus is a part. Assuming that all of the shares being
            registered under the registration statement of which this prospectus is a part are sold, there would be </font>353,558,419<font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">&#160;shares of common stock outstanding
            for voting purposes.&#160; As of March 8, 2019, approximately 28.8 million shares of our outstanding common stock were held by stockholders who are not affiliates of us. If sold into the public markets, the shares being registered under the
            registration statement of which this prospectus is a part would represent a significant portion of our public float following such sale (approximately 33%). In addition, approximately 11.9 million of the shares of our common stock being
            registered under the registration statement of which this prospectus is a part (representing our proportional interest in such shares) are currently excluded from the calculation of earnings per share because they are not considered outstanding
            for financial reporting purposes, and upon the sale of such shares, the number of shares used in the calculation of earnings per share would be increased.&#160; Sales of substantial amounts of our common stock in the public market by the selling
            stockholders, or the perception that those sales may occur, could cause the market price of our common stock to decline. In addition, the sale of these shares could impair our ability to raise capital through the sale of additional common
            stock.</font></font></div>
      <div><br>
      </div>
      <div style="text-align: left; margin-top: 0.4pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif; font-weight: bold; font-style: italic;">Purchasers may be unable to sell their common shares at or above their
          purchase price, and our stock price may be volatile.</font></div>

        <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">Even if all of the shares being registered under the registration statement of which this prospectus is a part
            are sold into the public markets, most of our shares will be held by one of our parent companies and we will have relatively few common shares outstanding in the public float.&#160; During the three months ended February 28, 2019, the average daily
            trading volume for our common stock as reported by the NYSE was approximately 345,000 shares.&#160;&#160;A more active market for our common stock may not develop or may not be sustained.&#160;&#160;The market price of our common stock could be subject to
            significant fluctuations, and you may not be able to resell your shares at or above your purchase price.</font></div>

          &#8220;forward-looking statements&#8221; within the meaning of Section&#160;27A of the Securities Act, and Section&#160;21E of the Exchange Act. Statements included in this prospectus, any accompanying prospectus supplement and the documents we incorporate by
          reference that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), are forward-looking statements. These
          statements can be identified by the use of forward-looking terminology including &#8220;forecast,&#8221; &#8220;may,&#8221; &#8220;believe,&#8221; &#8220;will,&#8221; &#8220;expect,&#8221; &#8220;anticipate,&#8221; &#8220;estimate,&#8221; &#8220;continue&#8221; or other similar words. These statements discuss future expectations, contain
          projections of results of operations or of financial condition or state other &#8220;forward-looking&#8221; information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.</font></div>

      </div>
      <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: &quot;Times New Roman&quot;,Times,serif;">These forward-looking statements are made based upon management&#8217;s current plans, expectations, estimates,
          assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those
