August 10, 2007 (LPAC)--After losing access to the commercial-paper market, Luminent Mortgage Capital isn't sure it can stay in business for much longer, according to Bloomberg News. The company suffered a liquidity loss due to "unanticipated disruptions in the secondary mortgage and national real estate markets," it explained in an Aug. 10 regulatory filing. The filing explained that due to the "significant" and "unprecedented" deterioration of the mortgage market, and the sources of financing it relies on, Luminent is now facing margin calls on its highest-quality assets, and can't borrow as much through repurchase agreements. The company has been forced to delay its quarterly report to the Security and Exchange Commission, and is now said to be exploring all its options.
