## Table 0 ##
(1) Home equity loan balances previously included in direct/indirect consumer and other consumer were reclassified to home equity to conform to current year presentation.
Additionally, certain foreign consumer balances were reclassified from other consumer to direct/indirect consumer to conform to current year presentation.
(2) Includes foreign consumer loans of $3.4 billion and $3.9 billion at December 31, 2007 and 2006.
(3) Includes other foreign consumer loans of $829 million and $2.3 billion, and consumer finance loans of $3.0 billion and $2.8 billion at December 31, 2007 and 2006.
(4) Includes small business commercial – domestic loans, primarily card-related, of $17.8 billion and $13.7 billion at December 31, 2007 and 2006.

(6) Certain commercial loans are measured at fair value in accordance with SFAS 159 and include commercial – domestic loans of $3.5 billion, commercial – foreign loans of $790 million and commercial real estate loans of $304 million at December 31, 2007.
See Note 19 – Fair Value Disclosures to the Consolidated Financial Statements for additional discussion of fair value for certain financial instruments.
n/a = not applicable The following table presents the recorded loan amounts, without consideration for the specific component of the allowance for loan and lease losses, that were considered individually impaired in accordance with SFAS 114 at December 31, 2007 and 2006.
SFAS 114 impairment includes performing troubled debt restructurings and excludes all commercial leases
## Table 1 ##
The average recorded investment in certain impaired loans for 2007, 2006 and 2005 was approximately $1.2 billion, $722 million and $852 million, respectively.
At December 31, 2007 and 2006, the recorded investment in impaired loans requiring an allowance for loan and lease losses based on individual analysis per SFAS 114 guidelines was $1.2 billion and $567 million, and the related allowance for loan and lease losses was $123 million and $43 million.
For 2007, 2006 and 2005, interest income recognized on impaired loans totaled $130 million, $36 million and $17 million, respectively, all of which was recognized on a cash basis.
At December 31, 2007 and 2006, nonperforming loans and leases, including impaired and nonaccrual consumer loans, totaled $5.6 billion and $1.8 billion.
In addition, included in other assets were consumer and commercial nonperforming loans held-for-sale of $188 million and $80 million at December 31, 2007 and 2006.
The Corporation has loan products with varying terms (e. g. , interest-only mortgages, option adjustable rate mortgages, etc. )
and loans with high loan-to-value ratios.
Exposure to any of these loan products does not result in a significant concentration of credit risk.
Terms of loan products, collateral coverage, the borrower’s credit history, and the amount of these loans that are retained on the Corporation’s balance sheet are included in the Corporation’s assessment when establishing its allowance for loan and lease losses
Note 19 – Fair Value Disclosures Effective January 1, 2007, the Corporation adopted SFAS 157, which provides a framework for measuring fair value under GAAP.
SFAS 157 also eliminated the deferral of gains and losses at inception of certain derivative contracts whose fair value was not evidenced by market observable data.
SFAS 157 requires that the impact of this change in accounting for derivative contracts be recorded as an adjustment to beginning retained earnings in the period of adoption.
The Corporation also adopted SFAS 159 on January 1, 2007.
SFAS 159 allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis.
The Corporation elected to adopt the fair value option for certain financial instruments on the adoption date.
SFAS 159 requires that the difference between the carrying value before election of the fair value option and the fair value of these instruments be recorded as an adjustment to beginning retained earnings in the period of adoption.
The following table summarizes the impact of the change in accounting for derivative contracts described above and the impact of adopting the fair value option for certain financial instruments on January 1, 2007.
Amounts shown represent the carrying value of the affected instruments before and after the changes in accounting resulting from the adoption of SFAS 157 and SFAS 159.
## Table 2 ##
(1) The transition adjustment reflects the impact of recognizing previously deferred gains and losses as a result of the rescission of certain requirements of EITF 02-3 in accordance with SFAS 157.
(2) Includes loans to certain large corporate clients.
The ending balance at December 31, 2006 and the transition adjustment were net of a $32 million reduction in the allowance for loan and lease losses.
(3) The January 1, 2007 balance after adoption represents the fair value of certain unfunded commercial loan commitments.
The December 31, 2006 balance prior to adoption represents the reserve for unfunded lending commitments associated with these commitments.
(4) Other assets include loans held-for-sale.
No transition adjustment was recorded for the loans held-for-sale because they were already recorded at fair value pursuant to lower of cost or market accounting.
(5) Changes in fair value of these AFS debt securities resulting from foreign currency exposure, which is the primary driver of fair value for these securities, had previously been hedged by derivatives that qualified for fair value hedge accounting in accordance with SFAS 133.
As a result, there was no transition adjustment.
Following the election of the fair value option, these AFS debt securities have been transferred to trading account assets.
(6) Includes structured reverse repurchase agreements that were hedged with derivatives in accordance with SFAS 133.
(7) Includes long-term fixed rate deposits that were economically hedged with derivatives.
Fair Value Option Elections Corporate Loans and Loan Commitments The Corporation elected to account for certain large corporate loans and loan commitments which exceeded the Corporation’s single name credit risk concentration guidelines at fair value in accordance with SFAS 159.
Lending commitments, both funded and unfunded, are actively managed and monitored, and, as appropriate, credit risk for these lending relationships may be mitigated through the use of credit derivatives, with the Corporation’s credit view and market perspectives determining the size and timing of the hedging activity.
These credit derivatives do not meet the requirements for hedge accounting under SFAS 133 and are therefore carried at fair value with changes in fair value recorded in other income.
Electing the fair value option allows the Corporation to account for these loans and loan commitments at fair value, which is more consistent with management’s view of the underlying economics and the manner in which they are managed.
In addition, accounting for these loans and loan commitments at fair value reduces the accounting asymmetry that would otherwise result from carrying the loans at historical cost and the credit derivatives at fair value.
Fair values for the loans and loan commitments are based on market prices, where available, or discounted cash flows using market-based credit spreads of comparable debt instruments or credit derivatives of the specific borrower or comparable borrowers.
Results of discounted cash flow calculations may be adjusted, as appropriate, to reflect other market conditions or the perceived credit risk of the borrower.
At December 31, 2007, funded loans which the Corporation has elected to fair value had an aggregate fair value of $4.59 billion recorded in loans and leases and an aggregate outstanding principal balance of $4.82 billion.
At December 31, 2007, unfunded loan commitments that the Corporation has elected to fair value had an aggregate fair value of $660 million recorded in accrued expenses and other liabilities and an aggregate committed exposure of $20.9 billion.
Interest income on these loans is recorded in interest and fees on loans and leases.
At December 31, 2007, none of these loans were 90 days or more past due and still accruing interest or had been placed on nonaccrual status.
Net losses resulting from changes in fair value of these loans and loan commitments of $413 million were recorded in other income during 2007.
These losses were significantly attributable to changes in instrumentspecific credit risk.
Following adoption of SFAS 159, approximately $5 million of direct loan origination fees and costs related to items for which the fair value option was elected were recognized in earnings during 2007.
Previously, these items would have been capitalized and amortized to earnings over the life of the loans.
seasoning and deterioration, and the level of commercial recoveries declined.
Noninterest expense increased $111 million, or five percent, primarily due to the LaSalle merger.
Capital Markets and Advisory Services CMAS provides financial products, advisory services and financing globally to our institutional investor clients in support of their investing and trading activities.
We also work with our commercial and corporate issuer clients to provide debt and equity underwriting and distribution capabilities, merger-related advisory services and risk management solutions using interest rate, equity, credit, currency and commodity derivatives, foreign exchange, fixed income and mortgage-related products.
The business may take positions in these products and participate in market-making activities dealing in government securities, equity and equity-linked securities, high-grade and high-yield corporate debt securities, commercial paper, mortgage-backed securities and ABS.
Underwriting debt and equity, securities research and certain market-based activities are executed through Banc of America Securities, LLC which is a primary dealer in the U. S.  In January 2008, we announced changes in our CMAS business which better align the strategy of this business with GCIB’s broader integrated platform.
We will continue to provide corporate, commercial and sponsored clients with debt and equity capital-raising services, strategic advice, and a full range of corporate banking capabilities.
We will reduce activities in certain structured products (e. g. , CDOs) and will resize the international platform to emphasize debt, cash management, and trading services, including rates and foreign exchange.
The realignment will result in the reduction of front office personnel with additional infrastructure headcount reduction to follow.
We also plan to sell our equity prime brokerage business.
CMAS evaluates its results using market-based revenue that is comprised of net interest income and noninterest income.
The following table presents further detail regarding market-based revenue.
Sales and trading revenue is segregated into fixed income from liquid products (primarily interest rate and commodity derivatives, foreign exchange contracts and public finance), credit products (primarily investment and noninvestment grade corporate debt obligations and credit derivatives), structured products (primarily CMBS, residential mortgage-backed securities, structured credit trading and CDOs), and equity income from equitylinked derivatives and cash equity activity.
## Table 3 ##
A variety of factors influence results including volume of activity, the degree in which we successfully anticipate market movements, and how our hedges perform in the various markets.
During the second half of 2007, extreme dislocations emerged in the financial markets, including leveraged finance, subprime mortgage, and the commercial paper markets, and these dislocations were further compounded by the decoupling of typical correlations in the various markets in which we participate.
These conditions created less liquidity, a flight to quality, greater volatility, widening of credit spreads and a lack of price transparency.
Furthermore, in the fourth quarter of 2007, the credit ratings of certain structured securities (e. g. , CDOs) were downgraded which among other things triggered further widening of credit spreads for this type of security.
We have been an active participant in the CDO market, maintain ongoing exposure to these securities and incurred losses associated with these exposures.
Many of these conditions continued into 2008 and it is unclear how long these conditions and the overall economic slowdown may continue and what impact they will ultimately have on our results.
CMAS recognized a net loss of $3.4 billion in 2007, a decrease of $5.0 billion, compared to 2006 driven by a decrease in market-based revenue of $8.2 billion.
The decrease was driven by $5.6 billion of losses resulting from our CDO exposure and other trading losses.
Partially offsetting this decrease was a reduction in noninterest expense due to lower performance-based incentive compensation.
Investment banking income increased $61 million to $2.5 billion due to growth in advisory fees.
This growth was driven by increased market activity primarily in the first half of the year partially offset by reduced debt underwriting fees that were affected by the market disruptions during the second half of the year which included the utilization of fees to distribute leveraged loan commitments.
Sales and trading revenue declined $8.3 billion to a loss of $2.3 billion in 2007.
While structured products and credit products reported losses for 2007, liquid products and equities compared reasonably well with 2006 given the market conditions.  ?
Liquid products revenue decreased $47 million as the negative impact of spread widening and correlations breaking down (e. g. , correlation between certain municipal market indices and bond market swap spreads) were partially offset by the strength in interest rate products and foreign exchange contracts.  ?
Credit products losses were $537 million, a decline in revenue of $1.4 billion compared to 2006.
Losses resulted from positions taken in the market as a result of customer market making activities as the widening of spreads during the second half of the year had a negative impact on these positions.
In addition, certain indices became extremely volatile and diverged from other related indices and from single name credit risk (bonds, loans or derivatives) in our portfolio.
This negatively impacted our hedging of portfolios of single name credits with derivatives based on these indices.
One example of this divergence was the widening of the spread between the investment grade cash and the credit derivative markets.
In addition, losses also resulted from positions taken in the market as the widening of spreads during the second half of the year had a negative impact on these positions.
We also incurred losses of $292 million, net of $471 million of fees, on leveraged loans, loan commitments and the Corporation’s share of the leveraged forward calendar.
Losses incurred on our leveraged exposure were not concentrated in any one type (senior secured, covenant light or subordinated/senior unsecured) and were generally due to wider new issuance credit spreads.
Since the negotiated spreads were lower than the then current new issuance spread, a fair value loss
Table 16 presents our commercial loans and leases and related credit quality information for 2007 and 2006.
Table 16 Commercial Loans and Leases
## Table 4 ##
(1) Nonperforming commercial loans and leases as a percentage of outstanding commercial loans and leases measured at historical cost were 0.67 percent and 0.31 percent at December 31, 2007 and 2006.
Including commercial loans and leases measured at fair value the ratio would have been 0.66 percent at December 31, 2007.
(2) Accruing commercial loans and leases past due 90 days or more as a percentage of outstanding commercial loans and leases measured at historical cost were 0.19 percent and 0.16 percent at December 31, 2007 and 2006.
Including commercial loans and leases measured at fair value the ratio would have remained unchanged at December 31, 2007.
(3) Includes a reduction in net charge-offs on commercial – domestic of $34 million, commercial – real estate of $27 million and commercial lease financing of $2 million as a result of the impact of SOP 03-3 for 2007.
Includes a reduction to small business commercial – domestic of $17 million as a result of the impact of SOP 03-3 for 2006.
The impact of SOP 03-3 on average outstanding loans and leases was not material.
(4) Net charge-off ratios are calculated as net charge-offs divided by average outstanding loans and leases measured at historical cost during the year for each loan and lease category.
(5) Excludes small business commercial – domestic loans.
(6) Outstandings include domestic commercial real estate loans of $60.2 billion and $35.7 billion, and foreign commercial real estate loans of $1.1 billion and $578 million at December 31, 2007 and 2006.
(7) Small business commercial – domestic is primarily card related.
(8) Certain commercial loans are measured at fair value in accordance with SFAS 159 and include commercial – domestic loans of $3.5 billion, commercial – foreign loans of $790 million and commercial real estate loans of $304 million at December 31, 2007.  n/a = not applicable Table 17 presents commercial credit exposure by type for utilized, unfunded and total binding committed credit exposure.
The increase in 2007 to commercial committed exposure was due to the addition of LaSalle and organic growth as discussed in the sections on the following pages.
The increase in derivative assets of $11.2 billion was centered in credit derivatives, interest rate and foreign exchange contracts, and was driven by growth in the businesses, widening credit spreads and the strengthening of foreign currencies against the U. S.  dollar.
Table 17 Commercial Credit Exposure by Type
## Table 5 ##
(1) Exposure includes standby letters of credit, financial guarantees, commercial letters of credit and bankers’ acceptances for which the bank is legally bound to advance funds under prescribed conditions, during a specified period.
Although funds have not been advanced, these exposure types are considered utilized for credit risk management purposes.
(2) Total commercial utilized exposure at December 31, 2007 includes loans and issued letters of credit measured at fair value in accordance with SFAS 159 and is comprised of loans outstanding of $4.59 billion and letters of credit at notional value of $1.1 billion.
(3) Total commercial unfunded exposure at December 31, 2007 includes loan commitments measured at fair value in accordance with SFAS 159 with a notional value of $19.8 billion.
(4) Excludes unused business card lines which are not legally binding.
(5) Derivative assets are reported on a mark-to-market basis, reflect the effects of legally enforceable master netting agreements, and have been reduced by cash collateral of $12.8 billion and $7.3 billion at December 31, 2007 and 2006.
In addition to cash collateral, derivative assets are also collateralized by $8.5 billion and $7.6 billion of primarily other marketable securities at December 31, 2007 and 2006 for which credit risk has not been reduced.
(6) Total commercial committed exposure consists of $23.9 billion and $11.0 billion of commercial loans held-for-sale exposure (e. g. , commercial mortgage and leveraged finance) and $4.1 billion and $14.0 billion of investments held-for-sale exposure at December 31, 2007 and 2006.
Estimates of synthetic crude oil reserves are prepared by GLJ Petroleum Consultants of Calgary, Canada, third-party consultants.
Their reports for all years are filed as exhibits to this Annual Report on Form 10-K.

Audits of Estimates Third-party consultants are engaged to provide independent estimates for fields that comprise 80 percent of our total proved reserves over a rolling four-year period for the purpose of auditing the in-house reserve estimates.
We met this goal for the fouryear period ended December 31, 2012.
We established a tolerance level of 10 percent such that initial estimates by the third-party consultants are accepted if they are within 10 percent of our internal estimates.
Should the third-party consultants’ initial analysis fail to reach our tolerance level, both our team and the consultants re-examine the information provided, request additional data and refine their analysis if appropriate.
This resolution process is continued until both estimates are within 10 percent.
In the very limited instances where differences outside the 10 percent tolerance cannot be resolved by year end, a plan to resolve the difference is developed and our senior management is informed.
This process did not result in significant changes to our reserve estimates in 2012 or 2011.
There were no third-party audits performed in 2010.
