In other news, the U.S. Treasury Department has extended the deadline for applications to its public-private initiative to buy up distressed assets from banks. The deadline has been pushed out two weeks until April 24.

The treasury's program allows fund managers to participate with the government in an initiative aimed at taking distressed assets off the balance sheets of banks. These assets have become nearly impossible to sell since the financial turmoil that set in last year, forcing banks to announce huge write-offs and putting the overall financial system in jeopardy.
