Tulsa-based BOK Financial Corp. has acquired the rights to service a $4.1 billion portfolio of mortgage loans from Albuquerque-based Charter Bank.

The 34,400 loans are largely concentrated in New Mexico, with the remainder representing Texas, Oklahoma, Kansas, Arizona, Colorado and Idaho. The loans to be serviced by BOK Financial are predominantly held by Fannie Mae, Freddie Mac and Ginnie Mae. The acquisition will mean a 46-percent increase of BOK Financial’s current $7.4 billion mortgage servicing portfolio.

“This is an attractive portfolio, and we are eager to serve the needs of our new customers,” said BOK Financial President and CEO Stan Lybarger.

The acquisition follows a successful year in 2009 for BOK Financial’s mortgage group, which funded just over $3 billion in loans in 2009, up sharply from $1.3 billion in 2008.

Although the acquisition is complete, the actual transfer of mortgage loans will take place in early April.

Kokoa exits downtown

It puts an ache in our sweet tooth to realize we can no longer run across the street to pick up chocolate delights at Kokoa Kabana, 510 S. Boston Ave.

We heard Stephen Howard, principal of local sweets shop Kokoa Chocolatier, closed the shop last month, consolidating operations in the Utica Square store, after nearly two years at the location.

Kokoa Kabana was a coffee concept offshoot of the original Kokoa Chocolatier and offered coffee, specialty sandwiches, salads and, of course, chocolate, to downtown Tulsans.
