Citizens is a bank holding company which was incorporated under Delaware state law in 1984 and whose primary federal regulator is the Board of Governors of the Federal Reserve System ("FRB"). As of December 31, 2018, our primary subsidiaries were Citizens Bank, N.A. ("CBNA"), a national banking association whose primary federal regulator is the Office of the Comptroller of the Currency ("OCC"), and Citizens Bank of Pennsylvania ("CBPA"), a Pennsylvania-chartered savings bank regulated by the Department of Banking of the Commonwealth of Pennsylvania and supervised by the Federal Deposit Insurance Corporation (the "FDIC") as its primary federal regulator. On January 2, 2019, we consolidated our banking subsidiaries via a merger of CBPA into CBNA in order to streamline governance and enterprise risk management, improve CBNA's risk profile and gain operational efficiencies. CBNA is now our primary subsidiary and our sole banking subsidiary.
We manage our business through two reportable business operating segments: Consumer Banking and Commercial Banking. The Company's activities outside the two business operating segments are classified as "Other" and include treasury activities, wholesale funding activities, securities portfolio, community development assets and other unallocated assets, liabilities, capital, revenues, provision for credit losses and expenses, including income tax expense. The Other classification also includes the financial impact of non-core, liquidating loan portfolios and other non-core assets and liabilities. For a description of non-core assets, see "Management's Discussion and Analysis of Financial Condition and Results of Operations - Analysis of Financial Condition - Loans and Leases - Non-Core Assets" in Part II, Item 7, of this Report.
