We estimate the sensitivity of our net interest income to changes in market interest rates using an interest rate simulation model that includes assumptions related to the level of balance sheet growth, deposit repricing characteristics and the rate of prepayments for multiple interest rate change scenarios.

The higher yield on interest-earning assets was primarily due to the impact of rising rates on adjustable rate assets and cash. The higher rate in interest-bearing liabilities was primarily due to higher rates on interest-bearing customer accounts combined with the higher interest rates on borrowings and customer accounts obtained in the Merger.
The lower yield on interest-earning assets was primarily due to the impact of falling rates on adjustable rate assets and cash. The lower rate in interest-bearing liabilities was primarily due to lower rates on interest-bearing customer accounts and combined with the pay-off of higher borrowings.
Improvement in the net interest income sensitivity during the year is primarily the result of interest rate swap activity, as well as increased time deposits and an increased federal funds balances which help reduce sensitivity in rising shock scenarios. Another method used to quantify interest rate risk is the NPV analysis.
