FHLB Advances and Other Borrowings FHLB Advances—The Company had $0.7 billion and $0.5 billion in floating-rate and $0.2 billion and $1.8 billion in fixed-rate FHLB advances at December 31, 2012 and 2011, respectively.
The floating-rate advances adjust quarterly based on the LIBOR.
During the year ended December 31, 2012, $650.0 million of fixed-rate FHLB advances were converted to floating-rate for a total cost of approximately $128 million which was capitalized and will be amortized over the remaining maturities using the effective interest method.
In addition, during the year ended December 31, 2012, the Company paid down in advance of maturity $1.0 billion of its FHLB advances and recorded $69.1 million in losses on the early extinguishment.
This loss was recorded in the gains (losses) on early extinguishment of debt line item in the consolidated statement of income (loss).
The Company did not have any similar transactions for the years ended December 31, 2011 and 2010.
As a condition of its membership in the FHLB Atlanta, the Company is required to maintain a FHLB stock investment currently equal to the lesser of: a percentage of 0.2% of total Bank assets; or a dollar cap amount of $26 million.
Additionally, the Bank must maintain an Activity Based Stock investment which is currently equal to 4.5% of the Bank’s outstanding advances at the time of borrowing.
On a quarterly basis, the FHLB Atlanta evaluates excess Activity Based Stock holdings for its members and makes a determination regarding quarterly redemption of any excess Activity Based Stock positions.
The Company had an investment in FHLB stock of $67.4 million and $140.2 million at December 31, 2012 and 2011, respectively.
The Company must also maintain qualified collateral as a percent of its advances, which varies based on the collateral type, and is further adjusted by the outcome of the most recent annual collateral audit and by FHLB’s internal ranking of the Bank’s creditworthiness.
These advances are secured by a pool of mortgage loans and mortgage-backed securities.
At December 31, 2012 and 2011, the Company pledged loans with a lendable value of $4.8 billion and $5.0 billion, respectively, of the one- to four-family and home equity loans as collateral in support of both its advances and unused borrowing lines.
Other Borrowings—Prior to 2008, ETBH raised capital through the formation of trusts, which sold trust preferred securities in the capital markets.
The capital securities must be redeemed in whole at the due date, which is generally 30 years after issuance.
Each trust issued Floating Rate Cumulative Preferred Securities (“trust preferred securities”), at par with a liquidation amount of $1,000 per capital security.
The trusts used the proceeds from the sale of issuances to purchase Floating Rate Junior Subordinated Debentures (“subordinated debentures”) issued by ETBH, which guarantees the trust obligations and contributed proceeds from the sale of its subordinated debentures to E*TRADE Bank in the form of a capital contribution.
The most recent issuance of trust preferred securities occurred in 2007.
The face values of outstanding trusts at December 31, 2012 are shown below (dollars in thousands):
## Table 0 ##
As of December 31, 2011, other borrowings also included $2.3 million of collateral pledged to the Bank by its derivatives counterparties to reduce credit exposure to changes in market value.
The Company did not have any similar borrowings for the year ended December 31, 2012.

(1) Metrics have been represented to exclude activity from discontinued operations for the year ended December 31, 2008, and international local market trading for the years ended December 31, 2009 and 2008.
(2) The Company transitioned from reporting under the OTS reporting requirements to reporting under the OCC reporting requirements in the first quarter of 2012.
The Tier 1 leverage ratio is the OCC Tier 1 leverage ratio as of December 31, 2012 and the OTS Tier 1 capital ratio at December 31, 2011, 2010, 2009 and 2008.
The OTS Tier 1 capital ratio and OCC Tier 1 leverage ratio are both calculated in the same manner using adjusted total assets.

Financial Statements and Supplementary Data
There is no goodwill assigned to reporting units within the balance sheet management segment.
The following table shows the amount of goodwill allocated to each of the reporting units and the fair value as a percentage of book value for the reporting units in the trading and investing segment (dollars in millions):
## Table 2 ##
We also evaluate the remaining useful lives on intangible assets each reporting period to determine whether events and circumstances warrant a revision to the remaining period of amortization.
Other intangible assets have a weighted average remaining useful life of 13 years.
We did not recognize impairment on our other intangible assets in the periods presented.
Effects if Actual Results Differ If our estimates of fair value for the reporting units change due to changes in our business or other factors, we may determine that an impairment charge is necessary.
Estimates of fair value are determined based on a complex model using estimated future cash flows and company comparisons.
If actual cash flows are less than estimated future cash flows used in the annual assessment, then goodwill would have to be tested for impairment.
The estimated fair value of the market making reporting unit as a percentage of book value was approximately 115%; therefore, if actual cash flows are less than our estimated cash flows, goodwill impairment could occur in the market making reporting unit in the future.
These cash flows will be monitored closely to determine if a further evaluation of potential impairment is necessary so that impairment could be recognized in a timely manner.
In addition, following the review of order handling practices and pricing for order flow between E*TRADE Securities LLC and GI Execution Services, LLC, our regulators may initiate investigations into our historical practices which could subject us to monetary penalties and cease-and-desist orders, which could also prompt claims by customers of E*TRADE Securities LLC.
Any of these actions could materially and adversely affect our market making and trade execution businesses, which could impact future cash flows and could result in goodwill impairment.
Intangible assets are amortized over their estimated useful lives.
If changes in the estimated underlying revenue occur, impairment or a change in the remaining life may need to be recognized.
Estimates of Effective Tax Rates, Deferred Taxes and Valuation Allowance Description In preparing the consolidated financial statements, we calculate income tax expense (benefit) based on our interpretation of the tax laws in the various jurisdictions where we conduct business.
This requires us to estimate current tax obligations and the realizability of uncertain tax positions and to assess temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities.
These differences result in deferred tax assets and liabilities, the net amount of which we show as other assets or other liabilities on the consolidated balance sheet.
We must also assess the likelihood that each of the deferred tax assets will be realized.
To the extent we believe that realization is not more likely than not, we establish a valuation allowance.
When we establish a valuation allowance or increase this allowance in a reporting period, we generally record a corresponding tax expense in the consolidated statement of income (loss).
Conversely, to the extent circumstances indicate that a valuation allowance is no longer necessary, that portion of the valuation allowance is reversed, which generally reduces overall income tax expense.
At December 31, 2012 we had net deferred tax assets of $1,416.2 million, net of a valuation allowance (on state, foreign country and charitable contribution deferred tax assets) of $97.8 million.
(5) Enterprise net interest spread represents the taxable equivalent rate earned on average enterprise interest-earning assets less the rate paid on average enterprise interest-bearing liabilities, excluding corporate interest-earning assets and liabilities.
The taxable equivalent adjustment to reconcile to net operating interest income was $1 million for each of the years ended December 31, 2015, 2014 and 2013.
