Two energy-related master limited partnerships were merged into affiliated businesses and among listed companies.

Williams Pipeline Partners LP was merged into Williams Partners LP, a $12 billion restructuring. Similarly, Magellan Midstream Holdings was dissolved and folded into Magellan Midstream Partners.

Nasdaq removed Vaughan Foods' stock from its listings after the Moore company's shares failed to maintain the exchange's minimum price standards.

Finally, Osage Bancshares, which was required to become a public company several years ago because of the manner in which it was created, voluntarily delisted its stock.
