1. Summary of Significant Accounting Policies

Principles of Consolidation

     All intercompany balances and transactions have been eliminated in consolidation. The Company's investment in entities with less than 20% ownership or in which the Company does not have the ability to influence the operations of the investee are accounted for using the cost method and are included in investments in joint ventures.

 

Allowance for Doubtful Accounts

     The Company establishes its allowance for doubtful accounts to the extent it is probable that a portion or all of a particular account will not be collected. The Company establishes its provision for doubtful accounts primarily by analyzing historical trends and the aging of receivables. In its evaluation, the Company considers other factors including: delays in payment trends in individual states due to budget or funding issues; billing conversions related to acquisitions or internal systems; resubmission of bills with required documentation and disputes with specific payors. An allowance for doubtful accounts is maintained at a level that the Company's management believes is sufficient to cover potential losses. However, actual collections could differ from the Company's estimates.
