The notes, which qualify as Tier 2 capital for Cullen/Frost, bear interest at the rate of 4.50% per annum, payable semi-annually on each March 17 and September 17.

Unamortized debt issuance costs related to these notes, totaled approximately $1.6 million at March 31, 2017. Proceeds from sale of the notes will be used for general corporate purposes.

See Note 8 - Borrowed Funds in our 2016 Form 10-K for additional information about these notes.
