(NYSE - NBP) today announced that the Securities and Exchange Commission (SEC) granted Enron's request on behalf of NBP to allow NBP to declare and pay distributions. NBP also will be able to invest as much as an additional $1 billion in energy assets, and to issue and sell debt and equity securities without further authorization from the SEC. The approval is part of an SEC order issued yesterday, after Enron registered as a holding company under the Public Utility Holding Company Act of 1935 (PUHCA). The authorizations are effective until the earlier of the deregistration of Enron under PUHCA or July 31, 2005. "This SEC action minimizes the potential for Northern Border's business to be adversely impacted by Enron's regulation under PUHCA," said Bill Cordes, chairman and chief executive officer of Northern Border Partners.
