CenterState Banks Inc. will close 13% of its retail branch network and cut 57 jobs following a drop in fourth quarter income. The company will close and consolidate 7 smaller branches and 1 stand-alone drive-thru facility effective in mid-April. The drive-thru is leased, and all of the branches are owned by the company.

Five of them will go up for sale after they close. The other two have tenants and will be used as loan production offices by the company. That will leave CenterState with 52 branch offices throughout central Florida.

The company also will restructure its credit administration and portfolio management divisions to streamline the approval process and to focus on larger credits. It also plans savings in the correspondent unit, wealth management department, health care related costs, and communications expenses after existing contracts mature. CenterState announced its restructuring and consolidation plans would cut annual operating expenses by about $6 million.

The company expects to take a $2.8 million charge in the current quarter for costs associated with the efficiency plans and an additional $2.3 million charge for expenses related to its purchase of Gulfstream Bancshares.
