Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Note 1 – Basis of Presentation and Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements of Newpark Resources, Inc. and our wholly-owned subsidiaries, which we refer to as “we,” “our” or “us,” have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (“SEC”), and do not include all information and footnotes required by the accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011. Our fiscal year end is December 31, our second quarter represents the three month period ended June 30 and our first half represents the six month period ending June 30. The results of operations for the second quarter and first half of 2012 are not necessarily indicative of the results to be expected for the entire year. Unless otherwise stated, all currency amounts are stated in U.S. dollars.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of June 30, 2012, the results of our operations for the second quarter and first half of 2012 and 2011, and our cash flows for the first half of 2012 and 2011. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2011 is derived from the audited consolidated financial statements at that date.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. For further information, see Note 1 in our Annual Report on Form 10-K for the year ended December 31, 2011.

New Accounting Standards

Each reporting period we consider all newly issued but not yet adopted accounting and reporting guidance applicable to our operations and the preparation of our consolidated financial statements. We do not believe that any issued accounting and reporting guidance we have not yet adopted will have a material impact on our financial statements at the time they may be adopted.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

Note 3 – Stock-Based Compensation

During the second quarter of 2012, the Compensation Committee of our Board of Directors approved equity-based compensation to executive officers and other key employees. These awards included a grant of 871,181 time-vesting shares of stock, which vest equally over a three-year period. The fair value on the date of grant for these awards was $5.57 per share. Non-employee directors received shares of restricted stock totaling 117,115 shares, which will vest in full on the first anniversary of the grant date.

Additionally, 1,438,158 stock options were granted to executive officers and other key employees at an exercise price of $5.57, which provides for equal vesting over a three-year period with a term of ten years. The estimated fair value of the stock options on the grant date using the Black-Scholes option-pricing model was $2.89. The assumptions used in the Black-Scholes model included a risk free interest rate of 0.68%, expected life of 5.22 years and expected volatility of 60.3%.

- Definition

The entire disclosure for compensation-related costs for equity-based compensation, which may include disclosure of policies, compensation plan details, allocation of equity compensation, incentive distributions, equity-based arrangements to obtain goods and services, deferred compensation arrangements, employee stock ownership plan details and employee stock purchase plan details.

Note 5 – Acquisition

In April 2011, we completed the acquisition of the drilling fluids and engineering services business from Rheochem PLC, a publicly-traded Australian-based oil and gas company. The acquired business provides drilling fluids and related engineering services to the oil and gas exploration and geothermal industries with operations in Australia, New Zealand and India. Total cash paid in 2011 was AUD$27.2 million ($28.8 million), including post-closing payments of AUD$0.8 million ($0.8 million) based on a true-up of the final working capital conveyed at closing and AUD$2.0 million ($2.1 million) related to a six month earn-out provision in the agreement. During the second quarter of 2012, the final payment was made which totaled AUD$11.9 million ($11.9 million), reflecting additional consideration required based on financial results of the acquired business over a one year earn-out period ended February 2012.

The transaction has been accounted for using the acquisition method of accounting and accordingly, assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date. The excess of the total consideration, including projected additional consideration, was recorded as goodwill and includes the value of the access to markets in Asia Pacific and an assembled workforce.

The following table summarizes the amounts recognized for assets acquired and liabilities assumed, as of the April 2011 acquisition date.

Deferred tax liability		3,432
Other noncurrent liabilities		271
Total liabilities assumed	$	20,663

Total cash conveyed at closing	$	25,916

The accrued liabilities at the date of acquisition in the table above includes $14.8 million reflecting the post-closing payments to the seller under the terms of the agreement, including $2.9 million that was paid during the third quarter of 2011 and the final payment of $11.9 million paid in the second quarter of 2012.

Proforma results of operation for the acquired business have not been presented as the effect of this acquisition is not material to our consolidated financial statements.

Note 7 – Financing Arrangements and Fair Value of Financial Instruments

Our financing arrangements include $172.5 million of unsecured convertible senior notes (“Senior Notes”) and a $125.0 million revolving credit facility, of which $66.0 million was outstanding at June 30, 2012. The Senior Notes bear interest at a rate of 4.0% per year, payable semi-annually in arrears on April 1 and October 1 of each year, beginning April 1, 2011. Holders may convert the Senior Notes at their option at any time prior to the close of business on the business day immediately preceding the October 1, 2017 maturity date. The conversion rate is initially 90.8893 shares of our common stock per $1,000 principal amount of Senior Notes (equivalent to an initial conversion price of $11.00 per share of common stock), subject to adjustment in certain circumstances. Upon conversion, the Senior Notes will be settled in shares of our common stock. We may not redeem the Senior Notes prior to their maturity date.

Our financial instruments include cash and cash equivalents, receivables, payables and debt. We believe the carrying values of these instruments, with the exception of our Senior Notes, approximated their fair values at June 30, 2012 and December 31, 2011. The estimated fair value of our Senior Notes is $158.6 million at June 30, 2012 and $195.8 million at December 31, 2011, based on Level 2 inputs including quoted market prices at these respective dates.
