[1] Includes revolving lines converted to term of $4.3 million of commercial and industrial, $1.0 million of owner-occupied commercial mortgage and $6.9 million of residential home equity.
[2] Certain fixed rate residential mortgage loans are included in a fair value hedging relationship. The amortized cost excludes an adjustment of $58,000 related to basis adjustments for loans in the closed portfolio under the portfolio layer method at March 31, 2025. These basis adjustments would be allocated to the amortized cost of specific loans within the pool if the hedge was de-designated. See "Note 7 - Derivatives" for more information on the fair value hedge.
