TD Ameritrade’s Strong Asset Gathering Momentum Continues

Net New Assets of $10.8 billion, 11% annualized growth rate

Record Client Assets of $452 billion

Diluted Earnings per Share of $0.25

OMAHA, Neb., April 17, 2012– TD Ameritrade Holding Corporation (NASDAQ: AMTD) has released results for the second quarter of fiscal 2012. The Company once again gathered assets at an industry-leading, double-digit growth rate and total client assets grew to a new record.

The Company’s results for the quarter ended Mar. 31, 2012 include the following (year-over-year comparisons):⁽¹⁾

• Net income of $137 million, or $0.25 per diluted share

• Net new client assets of $10.8 billion, an annualized growth rate of 11 percent of beginning client assets

• Average client trades per day of approximately 388,000

• Net revenues of $673 million, 54 percent of which were asset-based

• Operating income of $219 million, or 33 percent of net revenues

• Pre-tax income of $212 million, or 31 percent of net revenues

• EBITDA⁽²⁾ of $260 million, or 39 percent of net revenues

• Record interest rate sensitive assets⁽³⁾ of $79 billion, an increase of 13 percent

• Record client assets of approximately $452 billion, an increase of 10 percent

“TD Ameritrade continued to distinguish itself from its peers by again delivering double-digit asset gathering growth,” said Fred Tomczyk, president and chief executive officer. “Net new client assets of $10.8 billion bring client assets to a record $452 billion - double what they were just three years ago. We are now half-way through what we hope will be our fourth consecutive year of double digit asset gathering. This continued strong organic growth, combined with our robust return of capital strategy, has worked well for us during this difficult environment, and positions TD Ameritrade well to deliver enhanced shareholder value over the longer term.”

“TD Ameritrade had a solid quarter, growing net revenues sequentially despite a difficult operating environment that included continued near zero interest rates and low intraday volatility,” said Bill Gerber, executive vice president and chief financial officer. “Our net interest margin stabilized during the quarter

and we remain focused on diligently managing our expense levels. And, our strong financial position and unique business model have earned the Company its third credit rating upgrade from Standard & Poor’s since the beginning of the financial crisis. During that time, we have received rating increases covering six notches, or grade levels - more than any financial firm in the S&P 500.”

Stock Repurchases

During the second quarter of fiscal 2012, TD Ameritrade repurchased 775,000 shares of its common stock at an average price of $19.02 per share, for approximately $14.7 million. Year to date, the Company has repurchased 7.5 million shares at an average price of $16.23 per share.

As of Mar. 31, 2012, the Company had 29.2 million shares remaining on its existing stock repurchase authorization.

Quarterly Dividend

The Company has declared a $0.06 per share quarterly cash dividend, payable on May 15, 2012 to all holders of record of common stock as of May 1, 2012.

Credit Rating Upgrade

During the second quarter of fiscal 2012, Standard & Poor’s upgraded TD Ameritrade’s credit rating to “A”. This was the Company’s third S&P credit rating increase since the financial crisis began three and a half years ago.

Note: The term "GAAP" in the following explanation refers to generally accepted accounting principles in the United States.

(1) EBITDA (earnings before interest, taxes, depreciation and amortization) is considered a non-GAAP financial measure as defined by SEC Regulation G. We consider EBITDA an important measure of our financial performance and of our ability to generate cash flows to service debt, fund capital expenditures and fund other corporate investing and financing activities. EBITDA is used as the denominator in the consolidated leverage ratio calculation for covenant purposes under our holding company's senior revolving credit facility. EBITDA eliminates the non-cash effect of tangible asset depreciation and amortization and intangible asset amortization. EBITDA should be considered in addition to, rather than as a substitute for, pre-tax income, net income and cash flows from operating activities.

(2) Our liquid assets metrics are considered non-GAAP financial measures as defined by SEC Regulation G. We include the excess capital of our broker-dealer and trust company subsidiaries in the calculation of our liquid assets metrics, rather than simply including broker-dealer and trust company cash and cash equivalents, because capital requirements may limit the amount of cash available for dividend from the broker-dealer and trust company subsidiaries to the parent company. Excess capital, as defined below, is generally available for dividend from the broker-dealer and trust company subsidiaries to the parent company. We consider our liquid assets metrics to be important measures of our liquidity and of our ability to fund corporate investing and financing activities. The liquid assets metrics should be considered as supplemental measures of liquidity, rather than as substitutes for cash and cash equivalents.

We define liquid assets - management target as the sum of (a) corporate cash and cash equivalents, (b) corporate short-term investments and (c) regulatory net capital of (i) our clearing broker-dealer subsidiary in excess of 10% of aggregate debit items and (ii) our introducing broker-dealer subsidiaries in excess of a minimum operational target established by management ($50 million in the case of our primary introducing broker-dealer, TD Ameritrade, Inc.). We consider liquid assets - management target to be a measure that reflects our liquidity that would be readily available for corporate investing or financing activities under normal operating circumstances.

We define liquid assets - regulatory threshold as the sum of (a) corporate cash and cash equivalents, (b) corporate short-term investments, (c) regulatory net capital of (i) our clearing broker-dealer subsidiary in excess of 5% of aggregate debit items and (ii) our introducing broker-dealer subsidiaries in excess of the applicable early warning net capital requirement and (d) Tier 1 capital of our trust company in excess of the minimum dollar requirement. We consider liquid assets - regulatory threshold to be a measure that reflects our liquidity that would be available for corporate investing or financing activities under unusual operating circumstances.
