NEW YORK, Nov 11 (Reuters) - CBQ Financial on Wednesday sold $1.6 billion of debt in two parts in the Rule 144a private placement market, said IFR, a Thomson Reuters service.

The debt is guaranteed by the Commercial Bank of Qatar COMB.QA.

The sale included $1 billion of five-year senior unsecured notes priced to yield 283 basis points more than comparable U.S. Treasuries, and $600 million of 10-year subordinated debt yielding 414 basis points over Treasuries.

Credit Suisse and Morgan Stanley were the joint lead managers of the transaction. (Reporting by Pam Niimi; Editing by James Dalgleish)
