Operating Segment Information

. OPERATING SEGMENT INFORMATION

We manage our operations and prepare management reports and other information with a primary focus on geographical area. Following the close of business on December 31, 2015, we completed the merger of our subsidiary banks and certain non-banking subsidiaries, including Zions Management Services Company (“ZMSC”), with and into a single bank, ZB, N.A. We continue to manage our banking operations under our existing brand names, including Zions Bank, Amegy Bank, California Bank & Trust, National Bank of Arizona, Nevada State Bank, Vectra Bank Colorado, and The Commerce Bank of Washington. Performance assessment and resource allocation are based upon this geographical structure. Due to the charter consolidation, we have moved to an internal funds transfer pricing allocation system to report results of operations for business segments. Total average loans and deposits presented for the banking segments do not include intercompany amounts between banking segments, but may include deposits with the Other segment. Prior period amounts have been reclassified to reflect these changes.

As of March 31, 2016, Zions Bank operates 99 branches in Utah, 24 branches in Idaho, and one branch in Wyoming. Amegy operates 76 branches in Texas. CB&T operates 94 branches in California. NBAZ operates 65 branches in Arizona. NSB operates 49 branches in Nevada. Vectra operates 36 branches in Colorado and one branch in New Mexico. TCBW operates one branch in Washington and one branch in Oregon. Effective April 1, 2015, TCBO was merged into TCBW.

The operating segment identified as “Other” includes the Parent, ZMSC, certain nonbank financial service subsidiaries, and eliminations of transactions between segments. The Parent’s operations are significant to the Other segment. The Company’s net interest income is substantially affected by the Parent’s interest expense on long-term debt. The condensed statement of income identifies the components of income and expense which affect the operating amounts presented in the Other segment.

The accounting policies of the individual operating segments are the same as those of the Company. Transactions between operating segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations. Operating segments pay for centrally provided services based upon estimated or actual usage of those services.
