Federal Reserve Clears Columbia Bank Conversion, Greenlights Northfield Acquisition

Regulators approve Columbia Financial's mutual-to-stock conversion and purchase of Northfield Bancorp, creating a larger regional banking organization

By Leila Farooq

The Federal Reserve Board approved applications enabling Columbia Bank MHC and Columbia Financial, Inc. to convert from mutual to stock form and for Columbia Financial to acquire Northfield Bancorp, Inc. The approvals permit Columbia Financial to become a savings and loan holding company by acquiring Columbia Bank, and to acquire Northfield Bancorp and indirectly Northfield Bank. Post-transaction, Northfield Bancorp would be merged into Columbia Financial and Northfield Bank would be merged into Columbia Bank, leaving Columbia Financial with roughly $18.1 billion in consolidated assets.

Federal Reserve Clears Columbia Bank Conversion, Greenlights Northfield Acquisition

Key Points

  • Federal Reserve Board approved Columbia Bank MHC and Columbia Financial, Inc. to convert from mutual to stock form and to acquire Northfield Bancorp, Inc., enabling Columbia Financial to become a savings and loan holding company by acquiring Columbia Bank.
  • Post-transaction structure would merge Northfield Bancorp into Columbia Financial and Northfield Bank into Columbia Bank, producing combined consolidated assets of approximately $18.1 billion and making Columbia Financial the 110th largest insured depository organization in the United States.
  • The Board received two adverse comments but determined regulatory considerations supported approval; the Department of Justice reviewed potential competitive effects and did not conclude the proposal would be significantly adverse to competition. Sectors impacted include regional banking, deposit markets, and insured depository institutions in the Metro New York City and Philadelphia markets.

The Federal Reserve Board on Friday granted approvals to Columbia Bank MHC and Columbia Financial, Inc., both of Fair Lawn, New Jersey, allowing the organizations to proceed with a conversion from mutual to stock form and to complete a related acquisition of Northfield Bancorp, Inc.

Under the approvals, Columbia Financial, Inc. may become a savings and loan holding company through the acquisition of Columbia Bank of Fair Lawn, New Jersey. Columbia Financial also received clearance to acquire Northfield Bancorp of Woodbridge, New Jersey, which would entail the indirect acquisition of Northfield Bank of Staten Island, New York.

The approved transactions contemplate that, upon closing, Northfield Bancorp would be merged into Columbia Financial, and Northfield Bank would be merged into Columbia Bank. The combination would consolidate the organizations' assets and deposits under Columbia Financial and Columbia Bank management.

On a consolidated basis, Columbia Bank MHC reported approximately $11.0 billion in assets and controls about $8.5 billion in consolidated deposits. The Fed noted that those deposits represent less than 1 percent of total deposits held by insured depository institutions in the United States. Northfield Bancorp reported consolidated assets of about $5.8 billion and controls approximately $4.0 billion in consolidated deposits.

If the conversion and acquisition are consummated as proposed, Columbia Financial would have consolidated assets of approximately $18.1 billion and would rank as the 110th largest insured depository organization in the United States based on consolidated assets.

The Board disclosed that it received two adverse comments concerning the proposal. Despite those comments, the Board concluded that the statutory and regulatory considerations it reviewed were consistent with granting approval.

As part of its review of competitive effects, the Department of Justice examined the transaction and informed the Board that it did not conclude the proposal would have a significantly adverse effect on competition. The two organizations and their subsidiary banks do compete directly in the Metro New York City and Philadelphia banking markets, a factor that was considered during regulatory review.

The Fed also reported on capital adequacy. Columbia Bank MHC, Northfield Bancorp, and their subsidiary depository institutions are characterized as well capitalized. The Board found that following the proposed conversion Columbia Financial would be well capitalized, and that Columbia Bank would remain well capitalized upon completion of the proposed acquisition of Northfield Bancorp.


This approval clears the regulatory path for the mutual-to-stock conversion and the planned consolidation of Columbia and Northfield operations, subject to the parties consummating the transactions and meeting any additional conditions required by applicable law and regulatory practice.

Risks

  • The Board received two adverse comments about the proposal, indicating some public or stakeholder opposition that regulators considered in their review - this could reflect localized competitive or community concerns in regional banking markets.
  • Columbia Financial and Northfield Bancorp operate subsidiary banks that compete directly in Metro New York City and Philadelphia, so integration could face competitive dynamics or operational risks in those regional banking markets.
  • The approvals are conditional on consummation of the proposed conversion and acquisition; if the parties do not complete the transactions or fail to satisfy any further legal or regulatory requirements, the anticipated consolidation and asset figures would not be realized.
