15.	Common Stock

Each share of Class A Common Stock entitles its holder to one vote per share, and each share of Class B Common Stock generally entitles its holder to ten votes per share. The amount of any regular cash dividend payable on a share of Class A Common Stock will be an amount equal to 110% of the corresponding regular cash dividend payable on a share of Class B Common Stock. If a shareholder desires to sell shares of Class B Common Stock, such stock must be converted into shares of Class A Common Stock.

On August 4, 2008, our Board of Directors adopted a shareholder rights plan (the “Rights Plan”) designed to preserve shareholder value and the value of certain tax assets primarily associated with net operating loss (NOL) carryforwards and built-in losses under Section 382 of the Internal Revenue Code. Our ability to use NOLs and built-in losses would be limited if there was an “ownership change” under Section 382. This would occur if shareholders owning (or deemed under Section 382 to own) 5% or more of our stock increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a defined period of time. The Rights Plan was adopted to reduce the likelihood of an “ownership change” occurring as defined by Section 382. Under the Rights Plan, one right was distributed for each share of Class A Common Stock and Class B Common Stock outstanding as of the close of business on August 15, 2008. Effective August 15, 2008, if any person or group acquires 4.9% or more of the outstanding shares of Class A Common Stock without the approval of the Board of Directors, there would be a triggering event causing significant dilution in the voting power of such person or group. However, existing stockholders who owned, at the time of the Rights Plan’s adoption, 4.9% or more of the outstanding shares of Class A Common Stock will trigger a dilutive event only if they acquire additional shares. The approval of the Board of Directors’ decision to adopt the Rights Plan may be terminated by the Board of Directors at any time, prior to the Rights being triggered. The Rights Plan will continue in effect until August 15, 2018, unless it expires earlier in accordance with its terms. The approval of the Board of Directors’ decision to adopt the Rights Plan was submitted to a stockholder vote and approved at a special meeting of stockholders held on December 5, 2008. Also at the Special Meeting on December 5, 2008, our stockholders approved an amendment to our Certificate of Incorporation to restrict certain transfers of Class A Common Stock in order to preserve the tax treatment of our NOLs and built-in losses under Section 382 of the Internal Revenue Code. Subject to certain exceptions pertaining to pre-existing 5% stockholders and Class B stockholders, the transfer restrictions in the amended Certificate of Incorporation generally restrict any direct or indirect transfer (such as transfers of our stock that result from the transfer of interests in other entities that own our stock) if the effect would be to (i) increase the direct or indirect ownership of our stock by any person (or public group) from less than 5% to 5% or more of our common stock; (ii) increase the percentage of our common stock owned directly or indirectly by a person (or public group) owning or deemed to own 5% or more of our common stock; or (iii) create a new public group. Transfers included under the transfer restrictions include sales to persons (or public groups) whose resulting percentage ownership (direct or indirect) of common stock would exceed the 5% thresholds discussed above, or to persons whose direct or indirect ownership of common stock would by attribution cause another person (or public group) to exceed such threshold.

On July 3, 2001, our Board of Directors authorized a stock repurchase program to purchase up to 4 million shares of Class A Common Stock. There were no shares purchased during the three and nine months ended July 31, 2016. As of July 31, 2016, the maximum number of shares of Class A Common Stock that may yet be purchased under this program is 0.5 million.
