Stockholders’ Equity and EPS

Common Stock

In June 2010, we repurchased in its entirety the warrant previously issued to the U.S. Treasury in connection with our prior participation in the U.S. Treasury's Capital Purchase Program ("CPP"). The total cash repurchase price paid to the U.S. Treasury was $6.8 million for the aggregate warrant. At the time of issuance, the warrant was initially exercisable for 708,116 shares of our common stock at an exercise price of $49.78 per share. However, due to our completion of a qualified equity offering during the fourth quarter of 2009, the number of shares of common stock exercisable under the warrant was reduced to 354,058 pursuant to applicable CPP rules. The repurchase of the warrant reduced our stockholders' equity by the total cash price of $6.8 million, and did not have any impact on our net income available to common stockholders or diluted earnings per share in 2010.

Additional Paid-In Capital

At December 31, 2009, we had a 65 percent ownership interest in eProsper, an equity ownership data management services company. In December 2010, we acquired the remaining 35 percent ownership interest in eProsper for a total cash price of $1.3 million. This acquisition was accounted for as an equity transaction as we changed our ownership interest, while retaining control of our financial interest in eProsper. As a result, we reduced our stockholders' equity by $1.8 million, reflecting the total cash paid as well as the reduction of the noncontrolling interests' ownership portion.

Stockholders' Rights Plan

Our Board of Directors (the “Board”) has approved and adopted a stockholders' rights plan to, among other things, protect our stockholders from coercive takeover tactics. The current stockholders' rights plan is in effect through January 31, 2014 (the “Rights Plan”).

Under the Rights Plan, each stockholder of record on November 9, 1998 received a dividend of one right (a “Right”) for each outstanding share of common stock of the Company. The Rights are attached to, and presently only traded with, shares of the Company's common stock and are not currently exercisable. Except as specified below, upon becoming exercisable, each Right will entitle the holder to purchase from us 1/1000th of a share of the Company's Series A Participating Preferred Stock at a price of $175.00 per share.

The Rights will be exercisable on the tenth (10th) business day (or such later date as is determined by our Board) following the announcement that a person or group (other than the Company, its subsidiaries or their employee benefit plans) has acquired or announces a tender or exchange offer to acquire beneficial ownership of 15 percent or more of the Company's common stock. If a person or group acquires beneficial ownership of 15 percent or more of the Company's common stock, each Right will then be exercisable for shares of common stock having a value equal to two times the exercise price of the Right. Similarly, in the event the Company is acquired in a merger or other business combination transaction or 50 percent or more of our consolidated assets or earning power are sold following such time as a person or group has acquired beneficial ownership of 15 percent or more of the Company's common stock, the rights will be exercisable for shares of the acquirer or its parent having a value equal to two times the exercise price of the Right.

At any time on or prior to the close of business on the earlier of (i) the fifth day following a public announcement that a person or group (other than the Company, its subsidiaries or their employee benefit plans) has acquired beneficial ownership of 15 percent or more of the Company's outstanding common shares (or such later date as may be determined by action of the Board and publicly announced) or (ii) January 31, 2014, we may redeem the Rights in whole, but not in part, at a price of $0.001 per Right, subject to adjustment.

EPS

Basic EPS is the amount of earnings available to each share of common stock outstanding during the reporting period. Diluted EPS is the amount of earnings available to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options and restricted stock units outstanding under our equity incentive plans and our ESPP. Potentially dilutive common shares are excluded from the computation of dilutive EPS in periods in which the effect would be antidilutive. The following is a reconciliation of basic EPS to diluted EPS for 2012, 2011 and 2010:

Concurrent with the issuance of our 3.875% convertible senior notes ("3.875% Convertible Notes"), we entered into a convertible note hedge and warrant agreement. The warrants expired ratably over 60 business days beginning on July 15, 2011. The common shares under these warrants were excluded from the diluted EPS calculation for all periods presented as they were deemed to be anti-dilutive based on the conversion price of $64.43 per common share. For more information on our 3.875% Convertible Notes and the associated convertible note hedge and warrant agreement, see Note 11-“Short-Term Borrowings and Long-Term Debt” and Note 12-“Derivative Financial Instruments”.

Our $250 million 3.875% Convertible Notes matured on April 15, 2011. All of the notes were converted prior to maturity and we made an aggregate $260 million conversion settlement payment. We paid $250 million in cash (representing total principal) and $10 million through the issuance of 187,760 shares of our common stock (representing total conversion premium value). In addition, in connection with the conversion settlement, we received 186,736 shares of our common stock, valued at $10 million, from the associated convertible note hedge. Accordingly, there was not a significant impact on our total stockholders' equity with respect to settling the conversion premium value.
