Issuer Purchases of Equity Securities During the three months ended December 31, 2007, we repurchased 8,895,570 shares of our Class A common stock for an aggregate of $385.1 million pursuant to the $1.5 billion stock repurchase program publicly announced in February 2007, as follows:
## Table 0 ##
(1) Issuer repurchases pursuant to the $1.5 billion stock repurchase program publicly announced in February 2007.
Under this program, our management was authorized through February 2008 to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices as permitted by securities laws and other legal requirements, and subject to market conditions and other factors.
To facilitate repurchases, we typically made purchases pursuant to trading plans under Rule 10b5-1 of the Exchange Act, which allow us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods.
Subsequent to December 31, 2007, we repurchased 4.3 million shares of our Class A common stock for an aggregate of $163.7 million pursuant to this program.
In February 2008, our Board of Directors approved a new stock repurchase program, pursuant to which we are authorized to purchase up to an additional $1.5 billion of our Class A common stock.
Purchases under this stock repurchase program are subject to us having available cash to fund repurchases, as further described in Item 1A of this Annual Report under the caption “Risk Factors—We anticipate that we may need additional financing to fund our stock repurchase programs, to refinance our existing indebtedness and to fund future growth and expansion initiatives” and Item 7 of this Annual Report under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.

ments of operations during the second quarter of 2012.
We measured the fair values of the previously held investments based on the liquidation preferences and priority of the equity interests and debt, including accrued interest.
In addition, we prepaid the assumed debt obligation of Cameron for approximately $9 million during the second quarter of 2012.
The following summarizes the aggregate preliminary purchase price allocation for the 2012 acquisitions as of December 31, 2012 (in millions):
## Table 1 ##
We allocated a portion of the preliminary purchase price to specific intangible asset categories as of the respective acquisition dates as follows:
## Table 2 ##
Our technology-related intangible assets consist of technical processes, intellectual property, and institutional understanding with respect to products and processes that we will leverage in future products or processes and will carry forward from one product generation to the next.
The technology-related intangible assets are being amortized on a straight-line basis over their assigned estimated useful lives.
Purchased research and development represents the estimated fair value of acquired in-process research and development projects which have not yet reached technological feasibility.
These indefinitelived intangible assets are tested for impairment on an annual basis, or more frequently if impairment indicators are present, in accordance with U. S.  GAAP and our accounting policies.
Upon completion of the associated research and development efforts, we determine the useful life of the technology and begin amortizing the assets to reflect their use over their remaining lives.
The primary basis for determining the technological feasibility or completion of these projects is obtaining regulatory approval to market the underlying products.
We believe that the estimated intangible asset values represent the fair value at the dates of acquisition and do not exceed the amount a third party would pay for the assets.
We used the income approach to derive the fair value of the amortizable intangible assets and purchased research and development.
These fair value measurements are based on significant unobservable inputs, including management estimates and assumptions and, accordingly, are classified as Level 3 within the fair value hierarchy prescribed by ASC Topic 820, Fair Value Measurements and Disclosures.
We recorded the excess of the aggregate purchase price over the estimated fair values of the identifiable assets acquired as goodwill, which is non-deductible for tax purposes.
Goodwill was established due primarily to revenue and cash flow projections associated with future technologies, as well as synergies expected to be gained from the integration of these businesses into our existing operations, and has been allocated to our reportable segments based on the relative expected benefit as follows (in millions):

2011 Acquisitions Sadra Medical, Inc.  On January 4, 2011, we completed the acquisition of the remaining fully diluted equity of Sadra Medical, Inc.
Prior to the acquisition, we held a 14 percent equity ownership in Sadra.
Sadra is developing a fully repositionable and retrievable device for transcatheter aortic valve replacement (TAVR) to treat patients with severe aortic stenosis.
The Lotus?
Valve System consists of a stent-mounted tissue valve prosthesis and catheter delivery system for guidance and placement of the valve.
The low-profile delivery system and introducer sheath are designed to enable accurate positioning, repositioning and retrieval at any time prior to release of the aortic valve implant.
The acquisition was intended to broaden and diversify our product portfolio by expanding into the structural heart market, and TAVR is one of the fastest growing medical device markets.
We have integrated
market data by correlation or other means.
As of December 31, 2012, we have classified all of our derivative assets and liabilities within Level 2 of the fair value hierarchy prescribed by Topic 820, as discussed below, because these observable inputs are avail able for substantially the full term of our derivative instruments.
The following are the balances of our derivative assets and liabilities as of December 31, 2012 and December 31, 2011:
## Table 4 ##
(1) We classify derivative assets and liabilities as current when the remaining term of the derivative contract is one year or less.
Other Fair Value Measurements Recurring Fair Value Measurements On a recurring basis, we measure certain financial assets and financial liabilities at fair value based upon quoted market prices, where available.
Where quoted market prices or other observable inputs are not available, we apply valuation techniques to estimate fair value.
Topic 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements.
The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value.
The three levels of the hierarchy are defined as follows: ‰ Level 1 – Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.
‰ Level 2 – Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.
‰ Level 3 – Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk.
Assets and liabilities measured at fair value on a recurring basis consist of the following as of December 31, 2012 and December 31, 2011:

Our investments in money market and government funds are classified within Level 1 of the fair value hierarchy because they
