In general. (1) Except as otherwise provided in § 251.4, a company may not consummate a covered acquisition if upon consummation of the transaction, the liabilities of the resulting company would exceed 10 percent of the financial sector liabilities, and the company is or would become a financial company.

Financial sector liabilities. (i) Subject to paragraph (a)(2)(ii) of this section, as of July 1 of a given year, financial sector liabilities are equal to the average of the year-end financial sector liabilities figure for the preceding two calendar years. The measure of financial sector liabilities will be in effect until June 30 of the following calendar year.

For the period beginning July 1, 2015, and ending June 30, 2016, financial sector liabilities are equal to the year-end financial sector liabilities figure as of December 31, 2014.

The year-end financial sector liabilities figure equals the sum of the total consolidated liabilities of all top-tier U.S. financial companies (as calculated under paragraph (b) of this section) and the U.S. liabilities of all top-tier foreign financial companies (as calculated under paragraph (c) of this section) as of December 31 of that year.

On an annual basis and no later than July 1 of any calendar year, the Board will calculate and publish the financial sector liabilities for the preceding calendar year and the average of the financial sector liabilities for the preceding two calendar years.

Calculating total consolidated liabilities. For purposes of paragraph (a) of this section:

Covered acquisition by a U.S. company. For a covered acquisition in which a U.S. company would acquire a U.S. company or a foreign company, liabilities of the resulting U.S. financial company equal the consolidated liabilities of the resulting U.S. financial company, calculated on a pro forma basis in accordance with paragraph (c) of this section.

Covered acquisition by a foreign company of another foreign company. For a covered acquisition in which a foreign company would acquire another foreign company, liabilities of the resulting foreign financial company equal the U.S. liabilities of the resulting financial company, calculated on a pro forma basis in accordance with paragraph (d) of this section.

Covered acquisition by a foreign company of a U.S. company. For a covered acquisition in which a foreign company would acquire a U.S. company, liabilities of the resulting foreign financial company equal the sum of: (i) The U.S. liabilities of the foreign company immediately preceding the transaction (calculated in accordance with paragraph (d) of this section) and (ii) the consolidated liabilities of the U.S. company immediately preceding the transaction (calculated in accordance with paragraph (c) of this section), reduced by the amount corresponding to any balances and transactions that would be eliminated in consolidation upon consummation of the transaction.

Liabilities of a U.S. company—(1) U.S. company subject to applicable risk-based capital rules. For a U.S. company subject to applicable-risk based capital rules, consolidated liabilities are equal to:

Total risk-weighted assets of the company; plus

The amount of assets that are deducted from the company's regulatory capital elements under the applicable risk-based capital rules, times a multiplier that is equal to the inverse of the company's total risk-based capital ratio minus one; minus

Total regulatory capital of the company.

U.S. company not subject to applicable risk-based capital rules. For a U.S. company that is not subject to applicable risk-based capital rules, consolidated liabilities are equal to the total liabilities of such company on a consolidated basis, as determined under applicable accounting standards.

Liabilities of a foreign company—(1) Foreign banking organization. For a foreign banking organization, U.S. liabilities are equal to:

The total consolidated assets of each U.S. branch or U.S. agency of the foreign banking organization, calculated in accordance with applicable accounting standards; plus

The total consolidated liabilities of each top-tier U.S. subsidiary that is subject to applicable risk-based capital rules (or reports information to the Board regarding its capital under risk-based capital rules applicable to bank holding companies), calculated as:

Total consolidated risk-weighted assets of the subsidiary; plus

The amount of assets that are deducted from the subsidiary's regulatory capital elements under the applicable risk-based capital rules, times a multiplier that is equal to the inverse of the subsidiary's total risk-based capital ratio minus one; minus

Total consolidated regulatory capital of the subsidiary; plus

The total consolidated assets of each top-tier U.S. subsidiary that is not subject to applicable risk-based capital rules and does not report information regarding its capital under risk-based capital rules applicable to bank holding companies, calculated in accordance with applicable accounting standards.

Foreign financial company that is not a foreign banking organization. For a foreign company that is not a foreign banking organization, U.S. liabilities are equal to:

The total consolidated liabilities of each top-tier U.S. subsidiary that is subject to applicable risk-based capital rules (or reports information to the Board regarding its capital under risk-based capital rules applicable to bank holding companies), calculated as:

Total consolidated risk-weighted assets of the subsidiary; plus

The amount of assets that are deducted from the subsidiary's regulatory capital elements under the applicable risk-based capital rules, times a multiplier that is equal to the inverse of the company's total risk-based capital ratio minus one; minus

Total regulatory capital of the subsidiary; plus

The total consolidated liabilities of each top-tier U.S. subsidiary that is not subject to applicable risk-based capital rules, calculated in accordance with applicable accounting standards.

Intercompany balances and transactions—(i) Foreign banking organization. A foreign banking organization must reduce the amount of consolidated liabilities of its U.S. operations calculated pursuant to this paragraph (d) by amounts corresponding to intercompany balances and intercompany transactions between the foreign banking organization's U.S. domiciled affiliates, branches or agencies to the extent such items are not eliminated in consolidation, and increase consolidated liabilities by net intercompany balances and intercompany transactions between a non-U.S. domiciled affiliate and a U.S. domiciled affiliate, branch, or agency of the foreign banking organization, to the extent such items are not reflected in the measure of liabilities.

Foreign financial company. A foreign company that is not a foreign banking organization may reduce the amount of consolidated liabilities of its U.S. operations calculated pursuant to this paragraph (d) by amounts corresponding to intercompany balances and intercompany transactions between the foreign organization's U.S. domiciled affiliates to the extent such items are not already eliminated in consolidation; provided that it increases consolidated liabilities by net intercompany balances and intercompany transactions between a non-U.S. domiciled affiliate and a U.S. domiciled affiliate, to the extent such items are not already reflected in the measure of liabilities.

Applicable accounting standard. If a company does not calculate its total consolidated assets or liabilities under GAAP for any regulatory purpose (including compliance with applicable securities laws), the company may submit a request to the Board that the company use an accounting standard or method of estimation other than GAAP to calculate its liabilities for purposes of this part. The Board may, in its discretion and subject to Board review and adjustment, permit the company to provide estimated total consolidated liabilities on an annual basis using this accounting standard or method of estimation.
