Highlands’ subsidiaries generally consist of limited liability companies (“LLCs”). The effects of all significant intercompany transactions have been eliminated.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

The accompanying consolidated financial statements include the accounts of Highlands and its consolidated subsidiaries. Highlands consolidates its wholly-owned subsidiaries and any other entities which it controls (i) through voting rights or similar rights or (ii) by means other than voting rights if Highlands is the primary beneficiary of a variable interest entity (“VIE”). The portions of the equity and net income of consolidated subsidiaries that are not attributable to the Company are presented separately as amounts attributable to noncontrolling interests in our consolidated financial statements. Entities which Highlands does not control, and entities which are VIEs in which Highlands is not a primary beneficiary, if any, are accounted for under appropriate GAAP. Highlands’ subsidiaries generally consist of limited liability companies (“LLCs”). The effects of all significant intercompany transactions have been eliminated.
