§ 3.124 Merger and acquisition transitional arrangements. ( a ) *Mergers and acquisitions of companies without advanced systems.* If a national bank or Federal savings association merges with or acquires a company that does not calculate its risk-based capital requirements using advanced systems, the national bank or Federal savings association may use subpart D of this part to determine the risk-weighted asset amounts for the merged or acquired company's exposures for up to 24 months after the calendar quarter during which the merger or acquisition consummates. The OCC may extend this transition period for up to an additional 12 months. Within 90 days of consummating the merger or acquisition, the national bank or Federal savings association must submit to the OCC an implementation plan for using its advanced systems for the acquired company. During the period in which subpart D of this part applies to the merged or acquired company, any ALLL or AACL, as applicable, net of allocated transfer risk reserves established pursuant to 12 U.S.C. 3904, associated with the merged or acquired company's exposures may be included in the acquiring national bank's or Federal savings association's tier 2 capital up to 1.25 percent of the acquired company's risk-weighted assets. All general allowances of the merged or acquired company must be excluded from the national bank's or Federal savings association's eligible credit reserves. In addition, the risk-weighted assets of the merged or acquired company are not included in the national bank's or Federal savings association's credit-risk-weighted assets but are included in total risk-weighted assets. If a national bank or Federal savings association relies on this paragraph (a), the national bank or Federal savings association must disclose publicly the amounts of risk-weighted assets and qualifying capital calculated under this subpart for the acquiring national bank or Federal savings association and under subpart D of this part for the acquired company.
( b ) *Mergers and acquisitions of companies with advanced systems.* ( 1 ) If a national bank or Federal savings association merges with or acquires a company that calculates its risk-based capital requirements using advanced systems, the national bank or Federal savings association may use the acquired company's advanced systems to determine total risk-weighted assets for the merged or acquired company's exposures for up to 24 months after the calendar quarter during which the acquisition or merger consummates. The OCC may extend this transition period for up to an additional 12 months. Within 90 days of consummating the merger or acquisition, the national bank or Federal savings association must submit to the OCC an implementation plan for using its advanced systems for the merged or acquired company.
( 2 ) If the acquiring national bank or Federal savings association is not subject to the advanced approaches in this subpart at the time of acquisition or merger, during the period when subpart D of this part applies to the acquiring national bank or Federal savings association, the ALLL or AACL, as applicable associated with the exposures of the merged or acquired company may not be directly included in tier 2 capital. Rather, any excess eligible credit reserves associated with the merged or acquired company's exposures may be included in the national bank's or Federal savings association's tier 2 capital up to 0.6 percent of the credit-risk-weighted assets associated with those exposures.
