Business Segments

We have one reportable segment: Consumer. Our Consumer segment consists of our run-off Consumer Lending and Mortgage Services businesses. The Consumer segment provided real estate secured and personal non-credit card loans with both revolving and closed-end terms and with fixed or variable interest rates. Loans were originated through branch locations and direct mail. Products were also offered and customers serviced through the Internet. Our segment results are reported on a continuing operations basis. Prior to the first quarter of 2007, we acquired loans from correspondent lenders and prior to September 2007 we also originated loans sourced through mortgage brokers. While these businesses are operating in run-off, they have not been reported as discontinued operations because we continue to generate cash flow from the ongoing collections of the receivables, including interest and fees.

Previously we reported our corporate and treasury activities, which included the impact of FVO debt, in the All Other caption in our segment reporting. With the completion of the sale of our Insurance business on March 29, 2013 as more fully discussed in Note 3, “Discontinued Operations,” our corporate and treasury activities are now solely supporting our Consumer Lending and Mortgage Services businesses. As a result, beginning in the first quarter of 2013 we are now reporting these activities within the Consumer Segment and no longer presenting an “All Other” caption within segment reporting. Segment financial information has been restated for all periods presented to reflect this new segmentation. There have been no other changes in measurement or composition of our segment reporting as compared with the presentation in our 2012 Form 10-K.

We report financial information to our parent, HSBC, in accordance with International Financial Reporting Standards (“IFRSs”). Our segment results are presented in accordance with IFRSs (a non-U.S. GAAP financial measure) on a legal entity basis (“IFRSs Basis”) as operating results are monitored and reviewed and trends are evaluated on an IFRSs Basis. However, we continue to monitor liquidity and capital adequacy, establish dividend policy and report to regulatory agencies on a U.S. GAAP basis.

A summary of the significant differences between U.S. GAAP and IFRSs as they impact our results are presented below:

Net Interest Income

Effective interest rate - The calculation of effective interest rates under IAS 39, “Financial Instruments: Recognition and Measurement” (“IAS 39”), requires an estimate of changes in estimated contractual cash flows, including fees and points paid or received between parties to the contract that are an integral part of the effective interest rate be included. U.S. GAAP generally prohibits recognition of interest income to the extent the net investment in the loan would increase to an amount greater than the amount at which the borrower could settle the obligation. Under U.S. GAAP, prepayment penalties are generally recognized as received. U.S. GAAP also includes interest income on loans originated as held for sale which is included in other operating revenues for IFRSs.

Deferred loan origination costs and fees - Loan origination cost deferrals under IFRSs are more stringent and generally result in lower costs being deferred than permitted under U.S. GAAP. In addition, all deferred loan origination fees, costs and loan premiums must be recognized based on the expected life of the receivables under IFRSs as part of the effective interest calculation while under U.S. GAAP they may be recognized on either a contractual or expected life basis.

Net interest income - Under IFRSs, net interest income includes the interest element for derivatives which corresponds to debt designated at fair value. For U.S. GAAP, this is included in gain (loss) on debt designated at fair value and related derivatives which is a component of other revenues.

Other Operating Income (Total Other Revenues)

Loans held for sale - IFRSs requires loans originated with the intent to sell in the near term to be classified as trading assets and recorded at their fair value. Under U.S. GAAP, loans designated as held for sale are reflected as loans and recorded at the lower of amortized cost or fair value. Under IFRSs, the income and expenses related to receivables held for sale are reported in other operating income. Under U.S. GAAP, the income and expenses related to receivables held for sale are reported similarly to loans held for investment.

For receivables transferred to held for sale subsequent to origination, IFRSs requires these receivables to be reported separately on the balance sheet when certain criteria are met which are generally more stringent than those under U.S. GAAP, but does not change the recognition and measurement criteria. Accordingly, for IFRSs purposes such loans continue to be accounted for and impairment continues to be measured in accordance with IAS 39 with any gain or loss recorded at the time of sale. U.S. GAAP requires loans that meet the held for sale classification requirements be transferred to a held for sale category at the lower of amortized cost or fair value. Under U.S. GAAP, the component of the lower of amortized cost or fair value adjustment related to credit risk at the time of transfer is recorded in the statement of income (loss) as provision for credit losses while the component related to interest rates and liquidity factors is reported in the statement of income (loss) in other revenues.

Extinguishment of debt - During the fourth quarter of 2010, we exchanged $1.8 billion in senior debt for $1.9 billion in new fixed rate subordinated debt. Under IFRSs, the population of debt exchanged which qualified for extinguishment treatment was larger than under U.S. GAAP which resulted in a gain on extinguishment of debt under IFRSs compared to a small loss under U.S. GAAP.

Securities - Under IFRSs, securities include HSBC shares held for stock plans at fair value. These shares held for stock plans are measured at fair value through other comprehensive income. If it is determined that these shares have become impaired, the unrealized loss in accumulated other comprehensive income is reclassified to profit or loss. There is no similar requirement under U.S. GAAP.

Other-than-temporary impairments - Under U.S. GAAP, a decline in fair value of an available-for-sale debt security below its amortized cost may indicate that the security is other-than-temporarily impaired under certain conditions. IFRSs do not have an “other than temporary” impairment concept. Under IFRSs, a decline in fair value of an available-for-sale debt security below its amortized cost is considered evidence of impairment if the decline can, at least partially, be attributed to an incurred loss event that impacts the estimated future cash flows of the security (i.e., a credit loss event). Thus a security may not be considered impaired if the decline in value is the result of events that do not negatively impact the estimated future cash flows of the security (e.g., an increase in the risk-free interest rate). However, until the entity sells the security, it will have to assess the security for credit losses at each reporting date.

Another difference between U.S. GAAP and IFRSs is the amount of the loss that an entity recognizes in earnings on an impaired (other-than-temporarily impaired for U.S. GAAP) available-for-sale debt security. Under U.S. GAAP, if an entity has decided to sell a debt security whose fair value has declined below its amortized cost, or will be more likely than not required to sell the debt security before it recovers its amortized cost basis, it will recognize an impairment loss in earnings equal to the difference between the debt security's carrying amount and its fair value. If the entity has not decided to sell the debt security and will not be more likely than not required to sell the debt security before it recovers its amortized cost basis, but nonetheless expects that it will not recover the security's amortized cost basis, it will bifurcate the impairment loss into a credit loss component and a non-credit loss component, and recognize the credit loss component in earnings and the non-credit loss component in other comprehensive income. Under IFRSs, the entity recognizes the entire decline in fair value below amortized cost in earnings.

REO expense - Other revenues under IFRSs include losses on sale and the lower of amortized cost or fair value of the collateral less cost to sell adjustments on REO properties which are classified as other expense under U.S. GAAP.

Loan Impairment Charges (Provision for Credit Losses)

IFRSs requires a discounted cash flow methodology for estimating impairment on pools of homogeneous customer loans which requires the discounting of cash flows including recovery estimates at the original effective interest rate of the pool of customer loans. The amount of impairment relating to the discounting of future cash flows unwinds with the passage of time, and is recognized in interest income. Also under IFRSs, if the recognition of a write-down to fair value on secured loans decreases because collateral values have improved and the improvement can be related objectively to an event occurring after recognition of the write-down, such write-down is reversed, which is not permitted under U.S. GAAP. Additionally under IFRSs, future recoveries on charged-off loans or loans written down to fair value less cost to obtain title and sell the collateral are accrued for on a discounted basis and a recovery asset is recorded. Subsequent recoveries are recorded to earnings under U.S. GAAP, but are adjusted against the recovery asset under IFRSs. Under IFRSs, interest on impaired loans is recorded at the effective interest rate on the customer loan balance net of impairment allowances, and therefore reflects the collectability of the loans.

As discussed above, under U.S. GAAP the credit risk component of the initial lower of amortized cost or fair value adjustment related to the transfer of receivables to held for sale is recorded in the statement of income (loss) as provision for credit losses. There is no similar requirement under IFRSs.

Credit loss reserves on TDR Loans for U.S. GAAP are established based on the present value of expected future cash flows discounted at the loans' original effective interest rate. Under IFRSs, impairment on the residential mortgage loans where we have granted the borrower a concession as a result of financial difficulty is measured based on the cash flows attributable to the credit loss events which occurred before the reporting date. HSBC's accounting policy under IFRSs is to remove such loans from the category of impaired loans after a defined period of re-performance, although such loans remain segregated from loans that were not impaired in the past for the purposes of collective impairment assessment to reflect their credit risk. Under U.S. GAAP, when a loan is impaired the impairment is measured based on all expected cash flows over the remaining expected life of the loan. Such loans remain impaired for the remainder of their lives under U.S. GAAP.

For loans collectively evaluated for impairment under U.S. GAAP, bank industry practice adopted in the fourth quarter of 2012 generally results in a loss emergence period for these loans using a roll rate migration analysis which results in 12 months of losses in our credit loss reserves. Under IFRSs, we completed a review in the fourth quarter of 2012 which concluded that the estimated average period of time from current status to write-off for real estate secured loans collectively evaluated for impairment using a roll rate migration analysis was 10 months (previously a period of 7 months was used) which was also adopted in the fourth quarter of 2012.

Operating Expenses

Pension and other postretirement benefit costs - Pension expense under U.S. GAAP is generally higher than under IFRSs as a result of the amortization of the amount by which actuarial losses exceeds the higher of 10 percent of the projected benefit obligation or fair value of plan assets (the “corridor”). As a result of an amendment to the applicable IFRSs effective January 1, 2013, interest cost and expected return on plan assets is replaced by a finance cost component comprising the net interest on the net defined benefit liability. This has resulted in an increase in pension expense as the net interest does not reflect the benefit from the expectation of higher returns on the riskier plan assets. In 2010, changes to future accruals for legacy participants under the HSBC North America Pension Plan were accounted for as a plan curtailment under IFRSs, which resulted in immediate income recognition. Under U.S. GAAP, these changes were considered to be a negative plan amendment which resulted in no immediate income recognition.

Litigation accrual – Under U.S. GAAP litigation accruals are recorded when it is probable a liability has been incurred and the amount is reasonably estimable. Under IFRSs, a present obligation must exist for an accrual to be recorded. In certain cases, this creates differences in the timing of accrual recognition between IFRSs and U.S. GAAP.

Share-based bonus arrangements - Under IFRSs, the recognition of compensation expense related to share-based bonuses begins on January 1 of the current year for awards expected to be granted in the first quarter of the following year. Under U.S. GAAP, the recognition of compensation expense related to share-based bonuses does not begin until the date the awards are granted.

Assets

Customer loans (Receivables) - As discussed more fully above under "Other Operating Income (Total Other Revenues) - Loans held for sale," on an IFRSs basis, loans designated as held for sale at the time of origination and accrued interest are classified as trading assets. However, the accounting requirements governing when receivables previously held for investment are transferred to a held for sale category are more stringent under IFRSs than under U.S. GAAP. Unearned insurance premiums are reported as a reduction to receivables on a U.S. GAAP basis but are reported as insurance reserves for IFRSs. IFRSs also allows for reversals of write-downs to fair value on secured loans when collateral values have improved which is not permitted under U.S. GAAP.

Derivatives - Under U.S. GAAP, derivative receivables and payables with the same counterparty may be reported on a net basis in the balance sheet when there is an executed International Swaps and Derivatives Association, Inc. (“ISDA”) Master Netting Arrangement. In addition, under U.S. GAAP, fair value amounts recognized for the obligation to return cash collateral received or the right to reclaim cash collateral paid are offset against the fair value of derivative instruments. Under IFRSs, these agreements do not necessarily meet the requirements for offset, and therefore such derivative receivables and payables are presented gross on the balance sheet.
