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 $25 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 $140.2 million and $164.4 million at December 31, 2011 and 2010, 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, 2011 and 2010, the Company pledged loans with a lendable value of $5.0 billion and $5.6 billion, respectively, of the one- to four-family and home equity loans as collateral in support of both its advances and unused borrowing lines.
During the year ended December 31, 2009, the Company paid down in advance of maturity $1.6 billion of its FHLB advances.
The Company recorded a loss on the early extinguishment of FHLB advances of $50.6 million for the year ended December 31, 2009.
This loss is 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.
Other Borrowings—ETBH raised capital in the past through the formation of trusts, which sell 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, 2011 are shown below (dollars in thousands):
## Table 0 ##
As of December 31, 2011 and 2010, other borrowings also included $2.3 million and $19.3 million, respectively, of collateral pledged to the Bank by its derivatives counterparties to reduce credit exposure to changes in market value.
As of December 31, 2010, other borrowings also included $0.5 million of overnight and other short-term borrowings in connection with the Federal Reserve Bank’s treasury, tax and loan programs.
The Company pledged $0.8 million of securities to secure these borrowings from the Federal Reserve Bank as of December 31, 2010.
NOTE 19—REGULATORY REQUIREMENTS Registered Broker-Dealers The Company’s U. S.  broker-dealer subsidiaries are subject to the Uniform Net Capital Rule (the “Rule”) under the Securities Exchange Act of 1934 administered by the SEC and FINRA, which requires the maintenance of minimum net capital.
The minimum net capital requirements can be met under either the Aggregate Indebtedness method or the Alternative method.
Under the Aggregate Indebtedness method, a broker-dealer is required to maintain minimum net capital of the greater of 6 2?3% of its aggregate indebtedness, as defined, or a minimum dollar amount.
Under the Alternative method, a broker-dealer is required to maintain net capital equal to the greater of $250,000 or 2% of aggregate debit balances arising from customer transactions.
The method used depends on the individual U. S.  broker-dealer subsidiary.
The Company’s international broker-dealer subsidiaries, located in Europe and Asia, are subject to capital requirements determined by their respective regulators.
As of December 31, 2011, all of the Company’s broker-dealer subsidiaries met minimum net capital requirements.
Total required net capital was $0.1 billion at December 31, 2011.
In addition, the Company’s broker-dealer subsidiaries had excess net capital of $0.7 billion at December 31, 2011.
The table below summarizes the minimum excess capital requirements for the Company’s broker-dealer subsidiaries (dollars in thousands):

Banking E*TRADE Bank is subject to various regulatory capital requirements administered by federal banking agencies.
Failure to meet minimum capital requirements can trigger certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on E*TRADE Bank’s financial condition and results of operations.
Under capital adequacy guidelines and the regulatory framework for prompt corrective action, E*TRADE Bank must meet specific capital guidelines that involve quantitative measures of E*TRADE Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices.
In addition, E*TRADE Bank may not pay dividends to the parent company without approval from its regulators and any loans by E*TRADE Bank to the parent company and its other non-bank subsidiaries are subject to various quantitative, arm’s length, collateralization and other requirements.
E*TRADE Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
Quantitative measures established by regulation to ensure capital adequacy require E*TRADE Bank to maintain minimum amounts and ratios of Total and Tier I capital to risk-weighted assets and Tier I capital to adjusted total assets.
As shown in the table below, at both December 31, 2011 and 2010, the most recent notification from its regulators categorized E*TRADE Bank as “well capitalized” under the regulatory framework for prompt corrective action.
However, events beyond management’s control, such as a continued deterioration in residential real estate and credit markets, could adversely affect future earnings and E*TRADE Bank’s ability to meet its future capital requirements.
The following sections describe in detail the changes in key operating factors and other changes and events that affected net revenue, provision for loan losses, operating expense, other income (expense) and income tax expense (benefit).
Revenue The components of revenue and the resulting variances are as follows (dollars in millions):
## Table 2 ##
* Percentage not meaningful.
Net Operating Interest Income Net operating interest income decreased 3% to $1.2 billion for the year ended December 31, 2010 compared to 2009.
The slight decrease in net operating interest income was due primarily to a decrease in our average interest earning assets of $3.4 billion during the year ended December 31, 2010, which was offset by an increase in our net operating interest spread during the same period.
Average enterprise interest-earning assets decreased 8% to $41.1 billion for the year ended December 31, 2010 compared to 2009.
This decrease was primarily a result of the decrease in our average loans portfolio, average available-for-sale mortgage-backed securities and average cash and equivalents, partially offset by an increase in average margin receivables, average available-for-sale and held-to-maturity securities.
Average enterprise interest-bearing liabilities decreased 8% to $38.6 billion for the year ended December 31, 2010 compared to 2009.
The decrease in average enterprise interest-bearing liabilities was primarily due to decreases in average complete savings deposits and average certificates of deposit offset by an increase in average sweep deposits.
Enterprise net interest spread increased by 19 basis points to 2.91% for the year ended December 31, 2010 compared to 2009.
This increase was largely driven by a decrease in the yields paid on our deposits and lower wholesale borrowing costs, partially offset by a decrease in higher yielding enterprise interest-earning assets.
Commissions Commissions decreased 21% to $431.0 million for the year ended December 31, 2010 compared to 2009.
Our DART volume decreased 16% to 150,532 for the year ended December 31, 2010 compared 2009.
Option- related DARTs as a percentage of our total DARTs represented 17% of trading volume for the year ended December 31, 2010 compared to 13% in 2009.
Exchange-traded funds-related DARTs as a percentage of total DARTs represented 10% of trading volume for the year ended December 31, 2010 compared to 14% in 2009
Off-Balance Sheet Arrangements We enter into various off-balance-sheet arrangements in the ordinary course of business, primarily to meet the needs of our customers and to reduce our own exposure to interest rate risk.
These arrangements include firm commitments to extend credit and letters of credit.
Additionally, we enter into guarantees and other similar arrangements as part of transactions in the ordinary course of business.
For additional information on each of these arrangements, see Note 21—Commitments, Contingencies and Other Regulatory Matters of Item 8.
