Fair Value of Financial Instruments
Note 14: Fair Value of Financial Instruments
 
The Company's financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, derivative instruments and debt instruments. The book values of cash and cash equivalents, trade receivables, trade payables, derivative instruments and floating-rate debt instruments are considered to be representative of their respective fair values.

Cash and cash equivalents include highly liquid investments with a maturity of ninety days or less at the time of purchase. Cash equivalents consist primarily of money market securities, U.S. treasury bills, other U.S. agency notes, short-term commercial paper and corporate debt securities, all of which are considered Level 1 under the ASC's fair value hierarchy. Total cash equivalents were approximately $1.17 billion and $1.38 billion at September 30, 2011 and December 31, 2010, respectively.

Fair value of the Company's fixed rate debt (based on level 1 quoted market rates) was (in millions):

As indicated in Note 8 of the Notes to Consolidated Condensed Financial Statements, during the second quarter of 2011, the Company entered into an agreement with a third party financial intermediary for the purchase of 5.0 million call options on its common stock for a total premium payment of $21.9 million.  During the third quarter of 2011, the Company received net proceeds of $9.7 million for the settlement of 3.2 million options.  The remaining 1.8 million of options expired upon maturity as the market value of the options was below their strike price.

Proceeds received and changes in the estimated fair value of the call options were as follows (in millions):

In order to mitigate the effect of exchange rate changes, the Company will often attempt to structure sales contracts to provide for collections from customers in the currency in which the Company incurs its manufacturing costs. In certain instances, the Company will enter into forward foreign currency exchange contracts to hedge specific large anticipated receipts or disbursements in currencies for which the Company does not traditionally have fully offsetting local currency expenditures or receipts. The Company was party to a number of long-term foreign currency forward contracts at September 30, 2011, some of which extend through 2013. The purpose of the majority of these contracts was to hedge large anticipated non-functional currency cash flows on major subsea, drilling, valve or other equipment contracts involving the Company's United States operations and its wholly-owned subsidiaries in Italy, Romania, Singapore and the United Kingdom. Many of these contracts have been designated as and are accounted for as cash flow hedges with changes in the fair value of those contracts recorded in accumulated other comprehensive income in the period such change occurs.  Certain other contracts, many of which are centrally- managed, are intended to offset other foreign currency exposures but have not been designated as hedges for accounting purposes and, therefore, any change in the fair value of those contracts are reflected in earnings in the period such change occurs.  The Company determines the fair value of its outstanding foreign currency forward contracts based on quoted exchange rates for the respective currencies applicable to similar instruments.  These quoted exchange rates are considered to be Level 2 observable market inputs.  Information relating to the contracts as of September 30, 2011 follows:
