The combined financial statement is prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles. All intercompany accounts have been eliminated in combination.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Actual results could differ from those estimates.

Lease incentives, which are payments made to a tenant as an incentive to sign the lease, are amortized on a straight-line basis over the term of the lease as a reduction of rental revenue.

Real Estate

Expenditures for maintenance and repairs are charged to operations as incurred. Significant renovations or betterments that extend the economic useful life of the assets are capitalized.
