Cornerstone Bank: Securities Portfolio

Data as of · Call Report Schedule RC-B How we update

The investment portfolio: what the bank owns, how it is split between available-for-sale and held-to-maturity, and the unrealized gain or loss sitting in it. Unrealized losses on held-to-maturity securities do not run through capital, which is why the ratio to equity is worth watching.

Pledged share of securities climbed 6.30 percentage points in Q2 2026, from 65.86% to 72.15%. It was the largest change from Q1 2026 among the key lines here.
