Dell increases stake in SemGroup

The venture capital fund of computer maker Michael Dell has increased its stake in SemGroup Energy Partners LP, according to filings with the Securities and Exchange Commission.

MSD Capital LP bought 123,200 shares of common stock of the oil and asphalt transportation and storage provider at about $9.98 per unit. MSD also took over an additional 519,125 shares through an equity swap with New York-based Citibank, SEC filings show.

MSD now owns nearly 2.3 million shares, or about 10 percent, of SemGroup Energy Partners, the public subsidiary of collapsed Tulsa energy company SemGroup LP.

SemGroup LP filed for Chapter 11 bankruptcy on July 22 after apparently losing a reported $2.4 billion on the oil futures markets. It listed at least $2.5 billion owed to creditors.

Shares of SemGroup Energy Partners rose 2 cents to $10.40 on Friday. They have traded in a 52-week range of $5.98 to $30.50.
