The regulatory framework under which Nasdaq, OMX and PHLX operate and new regulatory requirements or new interpretations of existing regulatory requirements could require substantial time and resources for compliance, which could make it difficult and costly for the combined company to operate the businesses.
Under current U.S. federal securities laws, changes in Nasdaqs and PHLXs rules and operations, including pricing structure, must be reviewed, and in many cases explicitly approved by the SEC. The SEC may approve, disapprove, or recommend changes to proposals that Nasdaq and PHLX submit. In addition, the SEC may delay either the approval process or the initiation of the public comment process.
OMX is subject to regulatory oversight in all the countries in which it operates regulated businesses, such as operating exchanges or CSDs. The countries in which OMX is currently regulated are Sweden, Finland, Denmark, Iceland, Estonia, Lithuania and Latvia.
OMX has, in all the aforementioned countries, received authorization from the relevant authorities to conduct its regulated business activities. The authorities may revoke this authorization if OMX does not suitably carry out its regulated business activities. The authorities are also entitled to request that OMX adopt measures in order to ensure that OMX continues to fulfill the authorities requirements.
Furthermore, OMX holds minority stakes in other regulated entities. OMX owns approximately 10% of the Oslo Stock Exchange, approximately 24% of the United Kingdom derivatives exchange EDX London, 3% of the Bulgarian Stock Exchange and approximately 33% of the International Exchange St. Petersburg.
In addition, certain of OMXs customers also operate in a highly regulated industry. Regulatory authorities with jurisdiction over OMX and the exchanges it operates could impose regulatory changes that could impact the ability of OMXs customers to use one or more of the exchanges operated by OMX. The loss of a significant number of customers or a reduction in trading activity on any of the exchanges comprising the Nordic Exchange as a result of such changes could have a material adverse effect on the combined companys business, financial condition and operating results. Certain of OMXs customers are themselves exchanges which outsource certain technology functions to OMX, and thus the combined company would be particularly exposed to regulatory or other events impacting the global exchange industry.
