Basis of Presentation

Certain information and footnote disclosures normally included in the financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2018 Annual Report on Form 10-K.

The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the Consolidated Financial Statements for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed.

Leases

We determine whether a contract is or contains a lease at contract inception. Right-of-use (“ROU”) assets and long-term lease liabilities are presented as separate line items on our Consolidated Balance Sheets. Current operating lease liabilities are included in accrued expenses on our Consolidated Balance Sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. As the rate implicit in the lease is not readily determinable in most of our leases, we use our incremental borrowing rate.
