On November 1, 2010 (the “Acquisition Date”), MetLife, Inc.  completed the acquisition of American Life Insurance Company (“American Life”) from AM Holdings LLC (formerly known as ALICO Holdings LLC) (“AM Holdings”), a subsidiary of American International Group, Inc.  (“AIG”), and Delaware American Life Insurance Company (“DelAm”) from AIG (American Life, together with DelAm, collectively, “ALICO”) (the “Acquisition”).
ALICO’s fiscal year-end is November 30.
Accordingly, the Company’s consolidated financial statements reflect the assets and liabilities of ALICO as of November 30, 2011 and 2010, and the operating results of ALICO for the year ended November 30, 2011 and the one month ended November 30, 2010.
The assets, liabilities and operating results relating to the Acquisition are included in the Japan and Other International Regions segments.
Prior year results have been adjusted to conform to the current year presentation of segments.
See Note 2 of the Notes to the Consolidated Financial Statements.
We continue to experience an increase in market share and sales in several of our businesses; however, the general economic conditions, including the high levels of unemployment, negatively impacted the demand for certain of our products.
Portfolio growth in response to the higher sales levels drove improved investment results despite lower yields experienced in connection with the continued decline in interest rates in 2011.
The declining interest rate environment, however, also generated significant derivative gains in 2011.
Current year results were negatively impacted by severe weather, including the earthquake and tsunami in Japan in the first quarter, record numbers of tornadoes in the second quarter and Hurricane Irene in the third quarter.
## Table 0 ##
(1) See definitions of operating revenues and operating expenses for the components of such adjustments.
Year Ended December 31, 2011 compared with the Year Ended December 31, 2010 Unless otherwise stated, all amounts discussed below are net of income tax.
During the year ended December 31, 2011, income (loss) from continuing operations, net of income tax, increased $4.2 billion to $7.0 billion from $2.8 billion in 2010.
The change was predominantly due to a $5.1 billion favorable change in net derivative gains (losses), before income tax, and a $1.5 billion favorable change in operating earnings available to common shareholders, which includes the impact of the Acquisition.
The favorable change in net derivative gains (losses) of $3.3 billion was primarily driven by favorable changes in freestanding derivatives, partially offset by unfavorable changes in embedded derivatives.
The favorable change in freestanding derivatives was primarily attributable to the impact of falling long-term and mid-term interest rates and equity market movements and volatility.
The Acquisition drove the majority of the $1.5 billion increase in operating earnings available to common shareholders.
In addition, improved investment performance was the result of portfolio growth in response to increased sales across many of our businesses, which more than offset the negative impact of the declining interest rate environment on yields.
Current year results were negatively impacted by severe weather, as well as, in the third quarter, a charge to increase reserves in connection with the Company’s use of the U. S.  Social Security Administration’s Death Master File and similar databases to identify potential life insurance claims that have not been presented to the Company (“Death Master File”) and expenses incurred related to a liquidation plan filed by the New York State Department of Financial Services (the “Department of Financial Services”) for Executive Life Insurance Company of New York (“ELNY”).
Year Ended December 31, 2010 compared with the Year Ended December 31, 2009 Unless otherwise stated, all amounts discussed below are net of income tax.
During the year ended December 31, 2010, MetLife’s income (loss) from continuing operations, net of income tax increased $5.1 billion to a gain of $2.8 billion from a loss of $2.3 billion in 2009, of which $2 million in losses is from the inclusion of ALICO results for one month in 2010 and the impact of financing costs for the Acquisition.
The change was predominantly due to a $4.6 billion favorable change in net derivative gains (losses), before income tax, and a $2.5 billion favorable change in net investment gains (losses), before income tax.
Offsetting these favorable variances were unfavorable changes in adjustments related to continuing operations of $1.4 billion, before income tax, and $2.2 billion of income tax, resulting in a total favorable variance of $3.5 billion.
In addition, operating earnings available to common shareholders increased $1.6 billion to $3.8 billion in 2010 from $2.2 billion in 2009.
The favorable change in net derivative gains (losses) of $3.0 billion was primarily driven by net gains on freestanding derivatives in 2010 compared to net losses in 2009, partially offset by an unfavorable change in embedded derivatives from gains in 2009 to losses in 2010.
The favorable change in freestanding derivatives was primarily attributable to market factors, including falling long-term and mid-term interest rates, a stronger recovery in equity markets in 2009 than 2010, equity volatility, which decreased more in 2009 as compared to 2010, a strengthening U. S.  dollar and widening corporate credit spreads in the financial services sector.
The favorable change in net investment gains (losses) of $1.6 billion was primarily driven by a decrease in impairments and a decrease in the provision for credit losses on mortgage loans.
These favorable changes in net derivative and net investment gains (losses) were partially offset by an unfavorable change of $518 million in related adjustments.
The improvement in the financial markets, which began in the second quarter of 2009 and continued into 2010, was a key driver of the $1.6 billion increase in operating earnings available to common shareholders.
Such market improvement was most evident in higher net investment income and policy fees, as well as a decrease in variable annuity guarantee benefit costs.
These increases were partially offset by an increase in amortization of DAC, VOBA and deferred sales inducements (“DSI”) as a result of an increase in average separate account balances and higher 2010 gross margins in the closed block driven by increased investment yields and the impact of dividend scale reductions.
The 2010 period also includes one month of ALICO results, contributing $114 million to the increase in operating earnings.
The favorable impact of a reduction in discretionary spending associated with our
IMPAIRED LOANS Impaired loans include commercial nonperforming loans and consumer and commercial TDRs, regardless of nonperforming status.
Excluded from impaired loans are nonperforming leases, loans held for sale, smaller balance homogeneous type loans and purchased impaired loans.
See Note 6 Purchased Loans for additional information.
Nonperforming equipment lease financing loans of $12 million and $22 million at December 31, 2012 and December 31, 2011, respectively, are excluded from impaired loans pursuant to authoritative lease accounting guidance.
We did not recognize interest income on nonperforming impaired loans while they were in impaired loan status during 2012 and 2011.
The following table provides further detail on impaired loans individually evaluated for impairment and the associated ALLL.
Certain commercial impaired loans do not have a related ALLL as the valuation of these impaired loans exceeded the recorded investment.
## Table 1 ##
(a) Recorded investment in a loan includes the unpaid principal balance plus accrued interest and net accounting adjustments, less any charge-offs.
Recorded investment does not include any associated valuation allowance.
Average recorded investment is for the years ended December 31, 2012 and December 31, 2011.
(b) Associated allowance amounts include $587 million and $580 million for TDRs at December 31, 2012 and December 31, 2011, respectively.
(c) Pursuant to regulatory guidance issued in the third quarter of 2012, the impact of TDRs where no formal reaffirmation was provided by the borrower and therefore a concession has been granted based upon discharge from personal liability in bankruptcy is included in the table.
A portion of these loans have been written down to collateral value.
Table 153: Net Outstanding Standby Letters of Credit
## Table 2 ##
(a) Indicates that expected risk of loss is currently low.
(b) Indicates a higher degree of risk of default.
If the customer fails to meet its financial or performance obligation to the third party under the terms of the contract or there is a need to support a remarketing program, then upon the request of the guaranteed party, subject to the terms of the letter of credit, we would be obligated to make payment to them.
The standby letters of credit and risk participations in standby letters of credit and bankers’ acceptances outstanding on December 31, 2012 had terms ranging from less than 1 year to 7 years.
The aggregate maximum amount of future payments PNC could be required to make under outstanding standby letters of credit and risk participations in standby letters of credit and bankers’ acceptances was $14.7 billion at December 31, 2012, of which $7.5 billion support remarketing programs.
As of December 31, 2012, assets of $1.8 billion secured certain specifically identified standby letters of credit.
Recourse provisions from third parties of $3.2 billion were also available for this purpose as of December 31, 2012.
In addition, a portion of the remaining standby letters of credit and letter of credit risk participations issued on behalf of specific customers is also secured by collateral or guarantees that secure the customers’ other obligations to us.
The carrying amount of the liability for our obligations related to standby letters of credit and risk participations in standby letters of credit and bankers’ acceptances was $247 million at December 31, 2012.
STANDBY BOND PURCHASE AGREEMENTS AND OTHER LIQUIDITY FACILITIES We enter into standby bond purchase agreements to support municipal bond obligations.
At December 31, 2012, the aggregate of our commitments under these facilities was $587 million.
We also enter into certain other liquidity facilities to support individual pools of receivables acquired by commercial paper conduits.
At December 31, 2012, our total commitments under these facilities were $145 million.
INDEMNIFICATIONS We are a party to numerous acquisition or divestiture agreements under which we have purchased or sold, or agreed to purchase or sell, various types of assets.
These agreements can cover the purchase or sale of: ?
Entire businesses, ?
Loan portfolios, ?
Branch banks, ?
Partial interests in companies, or ?
Other types of assets.
These agreements generally include indemnification provisions under which we indemnify the third parties to these agreements against a variety of risks to the indemnified parties as a result of the transaction in question.
When PNC is the seller, the indemnification provisions will generally also provide the buyer with protection relating to the quality of the assets we are selling and the extent of any liabilities being assumed by the buyer.
Due to the nature of these indemnification provisions, we cannot quantify the total potential exposure to us resulting from them.
We provide indemnification in connection with securities offering transactions in which we are involved.
When we are the issuer of the securities, we provide indemnification to the underwriters or placement agents analogous to the indemnification provided to the purchasers of businesses from us, as described above.
When we are an underwriter or placement agent, we provide a limited indemnification to the issuer related to our actions in connection with the offering and, if there are other underwriters, indemnification to the other underwriters intended to result in an appropriate sharing of the risk of participating in the offering.
Due to the nature of these indemnification provisions, we cannot quantify the total potential exposure to us resulting from them.
In the ordinary course of business, we enter into certain types of agreements that include provisions for indemnifying third parties.
We also enter into certain types of agreements, including leases, assignments of leases, and subleases, in which we agree to indemnify third parties for acts by our agents, assignees and/or sublessees, and employees.
We also enter into contracts for the delivery of technology service in which we indemnify the other party against claims of patent and copyright infringement by third parties.
Due to the nature of these indemnification provisions, we cannot calculate our aggregate potential exposure under them.
In the ordinary course of business, we enter into contracts with third parties under which the third parties provide services on behalf of PNC.
In many of these contracts, we agree to indemnify the third party service provider under certain circumstances.
The terms of the indemnity vary from contract to contract and the amount of the indemnification liability, if any, cannot be determined.
We are a general or limited partner in certain asset management and investment limited partnerships, many of which contain indemnification provisions that would require us to make payments in excess of our remaining unfunded commitments.
While in certain of these partnerships the maximum liability to us is limited to the sum of our unfunded commitments and partnership distributions received by us, in the others the indemnification liability is unlimited.
As a result, we cannot determine our aggregate potential exposure for these indemnifications.
