First Citizens BancShares, Inc.(以下簡稱“我們”、“我方”或“BancShares”)就此次提交的現行報告書8-k(以下簡稱“本報告”)對我們在2024年2月23日向美國證券交易委員會(以下簡稱“SEC”)提交的截至2023年12月31日的年度報告書10-k(以下簡稱“我們的2023年10-K”)中包括的某些歷史財務信息及相關公示進行回顧性修訂,以符合下文所述的部門報告變更。

在我們的2023年10-K表格中,部門披露包括通用銀行、商業銀行、矽谷銀行、鐵路部門和企業的財務業績。正如我們於2024年5月9日向美國證券交易委員會提交的2024年第一季度季報表格10-Q中所披露的,我們在2024年第一季度對我們的部門報告進行了以下更改:
矽谷銀行(“SVB”)的私人銀行和財富管理元件被整合到已包括其他財富管理活動的綜合銀行部門中;
由於它的客戶主要涉及關鍵創新市場的商業客戶、股權投資和創投客戶,因此SVb板塊改名為SVb商業。
原本屬於綜合銀行部門的全國數字化銀行平台「Direct Bank」已轉移至企業銀行部門,該部門已包括借款和代理存款。

所有板塊的第二季度和第一季度10-Q表格中的分段披露和相關信息已經遵循了我們可報告分段的上述變更。

本報告第9.01項所附之附錄99.1所述內容已納入本報告中,因應我們經營部門變更,本公司2023年度10-K表格的以下項目已進行回顧性修改:
第一部分,項目1。業務,
第 II 部分,項目 7。管理層對財務狀況和營運結果的討論和分析,以及
第二部分,第8項。基本報表和補充資料。
此報告,包括附件 99.1,不反映我們提交 2023 年 10-K 表格後發生的活動或事件,並且不 modify 或更新我們 2023 年 10-K 表格中的信息或披露,除了反映上述的分段報告變更。本報告中的信息,包括附件 99.1,應與我們的 2023 年 10-K 表格,我們 2024 年 6 月 30 日和 3 月 31 日的 10-Q 表格以及我們後續在 SEC 提交的其他文件一起閱讀。
