AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The following table summarizes the preliminary allocation of the aggregate purchase consideration paid and the amounts of assets acquired and liabilities assumed based upon their estimated fair value at the date of acquisition (in thousands):
## Table 0 ##
(1) Consists of customer-related intangibles of approximately $80.0 million and network location intangibles of approximately $38.0 million.
The customer-related intangibles and network location intangibles are being amortized on a straight-line basis over periods of up to 20 years.
(2) The Company expects that the goodwill recorded will be deductible for tax purposes.
The goodwill was allocated to the Company’s international rental and management segment.
Ghana Acquisition—On December 6, 2010, the Company entered into a definitive agreement with MTN Group Limited (“MTN Group”) to establish a joint venture in Ghana.
The joint venture is controlled by a holding company of which a wholly owned subsidiary of the Company (the “ATC Ghana Subsidiary”) holds a 51% interest and Mobile Telephone Networks (Netherlands) B. V. , a wholly owned subsidiary of MTN Group (the “MTN Ghana Subsidiary”) holds a 49% interest.
The joint venture is managed and controlled by the Company and owns a tower operations company in Ghana.
Pursuant to the agreement, on May 6, 2011, August 11, 2011 and December 23, 2011, the joint venture acquired 400, 770 and 686 communications sites, respectively, from MTN Group’s operating subsidiary in Ghana for an aggregate purchase price of $515.6 million (including contingent consideration of $2.3 million and value added tax of $65.6 million).
The aggregate purchase price was subsequently increased to $517.7 million (including contingent consideration of $2.3 million and value added tax of $65.6 million) after certain post-closing adjustments.
Under the terms of the purchase agreement, legal title to certain of the communications sites acquired on December 23, 2011 will be transferred upon fulfillment of certain conditions by MTN Group.
Prior to the fulfillment of these conditions, the Company will operate and maintain control of these communications sites, and accordingly, reflect these sites in the allocation of purchase price and the consolidated operating results.
In December 2011, the Company signed an amendment to its agreement with MTN Group, which requires the Company to make additional payments upon the conversion of certain barter agreements with other wireless carriers to cash-paying master lease agreements.
The Company currently estimates the fair value of remaining potential contingent consideration payments required to be made under the amended agreement to be between zero and $1.0 million and is estimated to be $0.9 million using a probability weighted average of the expected outcomes at December 31, 2012.
The Company has previously made payments under this arrangement of $2.6 million.
During the year ended December 31, 2012, the Company recorded an increase in fair value of $0.4 million as other operating expenses in the consolidated statements of operations.
Regulatory Capital Standards Developments The prospective regulatory capital standards for financial institutions are currently subject to significant debate, rulemaking activity and uncertainty, both in the U. S.  and internationally.
See “Risk Factors” below.
Basel II and III.
In late 2005, the Basel Committee on Banking Supervision (Basel Committee) published a new set of risk-based capital standards (Basel II) that would permit banking organizations, including Citigroup, to leverage internal risk models used to measure credit, operational, and market risk exposures to drive regulatory capital calculations.
In late 2007, the U. S.  banking agencies adopted these standards for large banking organizations, including Citigroup.
As adopted, the standards require Citigroup, as a large and internationally active banking organization, to comply with the most advanced Basel II approaches for calculating credit and operational risk capital requirements.
The U. S.  implementation timetable consists of a parallel calculation period under the current regulatory capital regime (Basel I) and Basel II, followed by a threeyear transitional period.
Citi began parallel reporting on April 1, 2010.
There will be at least four quarters of parallel reporting before Citi enters the three-year transitional period.
The U. S.  banking agencies have reserved the right to change how Basel II is applied in the U. S.  following a review at the end of the second year of the transitional period, and to retain the existing prompt corrective action and leverage capital requirements applicable to banking organizations in the U. S.  Apart from the Basel II rules regarding credit and operational risks, in June 2010, the Basel Committee agreed on certain revisions to the market risk capital framework that would also result in additional capital requirements.
In December 2010, the U. S.  banking agencies issued a proposal that would amend their market risk capital rules to implement certain revisions approved by the Basel Committee to the market risk capital framework.
Further, as an outgrowth of the financial crisis, in December 2010, the Basel Committee issued final rules to strengthen existing capital requirements (Basel III).
The U. S.  banking agencies will be required to finalize, within two years, the rules to be applied by U. S.  banking organizations commencing on January 1, 2013.
Under Basel III, when fully phased in on January 1, 2019, Citigroup would be required to maintain risk-based capital ratios as follows:
## Table 1 ##
While banking organizations may draw on the 2.5% capital conservation buffer to absorb losses during periods of financial or economic stress, restrictions on earnings distributions (e. g. , dividends, equity repurchases, and discretionary compensation) would result, with the degree of such restrictions greater based upon the extent to which the buffer is utilized.
Moreover, subject to national discretion by the respective bank supervisory or regulatory authorities, a countercyclical capital buffer ranging from 0% to 2.5%, consisting of common equity or other fully loss absorbing capital, would also be imposed on banking organizations when it is deemed that excess aggregate credit growth is resulting in a build-up of systemic risk in a given country.
This countercyclical capital buffer, when in effect, would serve as an additional buffer supplementing the capital conservation buffer.
As a systemically important financial institution, Citigroup may also be subject to additional capital requirements.
The Basel Committee and the Financial Stability Board are currently developing an integrated approach to systemically important financial institutions that could include combinations of capital surcharges, contingent capital and bail-in debt.
Under Basel III, Tier 1 Common capital will be required to be measured after applying generally all regulatory adjustments (including applicable deductions).
The impact of these regulatory adjustments on Tier 1 Common capital would be phased in incrementally at 20% annually beginning on January 1, 2014, with full implementation by January 1, 2018.
During the transition period, the portion of the regulatory adjustments (including applicable deductions) not applied against Tier 1 Common capital would continue to be subject to existing national treatments.
Moreover, under Basel III certain capital instruments will no longer qualify as non-common components of Tier 1 Capital (e. g. , trust preferred securities and cumulative perpetual preferred stock) or Tier 2 Capital.
These instruments will be subject to a 10% per-year phase-out over 10 years beginning on January 1, 2013, except for certain limited grandfathering.
This phase-out period will be substantially shorter in the U. S.  as a result of the so-called “Collins Amendment” to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which will generally require a phase out of these securities over a three-year period also beginning on January 1, 2013.
In addition, the Basel Committee has subsequently issued supplementary minimum requirements to those contained in Basel III, which must be met or exceeded in order to ensure that qualifying non-common Tier 1 or Tier 2 Capital instruments fully absorb losses at the point of a banking organization’s non-viability before taxpayers are exposed to loss.
These requirements must be reflected within the terms of the capital instruments unless, subject to certain conditions, they are implemented through the governing jurisdiction’s legal framework.
Although U. S.  banking organizations, such as Citigroup, are currently subject to a supplementary, non-risk-based measure of leverage for capital adequacy purposes (see “Capital Ratios” above), Basel III establishes a more constrained Leverage ratio requirement.
Initially, during a four-year parallel run beginning on January 1, 2013, banking organizations will be required to maintain a minimum 3% Tier 1 Capital Leverage ratio.
Disclosure of such ratio, and its components, will start on January 1, 2015.
Depending upon the results of the parallel run test period, there could be subsequent adjustments to the definition and calibration of the Leverage ratio, which is to be finalized in 2017 and become a formal requirement by January 1, 2018.
Non-Accrual Loans and Assets (continued) The table below summarizes Citigroup’s other real estate owned (OREO) assets.
This represents the carrying value of all property acquired by foreclosure or other legal proceedings when Citi has taken possession of the collateral.
## Table 2 ##
(1) The $6.403 billion of non-accrual loans transferred from the held-for-sale portfolio to the held-for-investment portfolio during the fourth quarter of 2008 were marked to market at the transfer date and, therefore, no allowance was necessary at the time of the transfer.
$2.426 billion of the par value of the loans reclassified was written off prior to transfer.
(2) The allowance for loan losses includes the allowance for credit card and purchased distressed loans, while the non-accrual loans exclude credit card balances and purchased distressed loans as these continue to accrue interest until write-off.
## Table 3 ##
(1) The allowance for loan losses includes the allowance for credit card and purchased distressed loans, while the non-accrual loans exclude credit card balances (with the exception of certain international portfolios) and purchased distressed loans as these continue to accrue interest until write-off.
