3. Use of Estimates and Uncertainties

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The Company uses estimates to calculate an allowance for doubtful accounts on its accounts receivables, adequacy of reserves, the tax rate applied and the valuation of certain assets and liability accounts. These estimates can be significant to the operating results and financial position of the Company.

The Company has risk participation arrangements with respect to workers compensation and health care insurance. The amounts included in the Company’s costs related to this risk participation are estimated and can vary based on changes in assumptions, the Company’s claims experience or the providers included in the associated insurance programs.

The Company can be affected by a variety of factors including uncertainty relating to the performance of the general economy, competition, demand for the Company’s services, adverse litigation and claims and the hiring, training and retention of key employees.

Fair Value of Financial Instruments

The Company’s carrying value of financial instruments, consisting primarily of accounts receivable, accounts payable and accrued expenses, approximates fair value due to their liquidity or their short-term nature. The Company does not have derivative products in place to manage risks related to foreign currency fluctuations for its foreign operations or for interest rate changes.
