The tenant in-place, above-market and below-market lease intangible assets and the above-market and below-market ground lease intangible assets resulted from real estate acquisitions. The in‑place value and above-market value of tenant leases are included in Prepaid expenses and other assets in our Consolidated Balance Sheets and are amortized over periods that approximate the related lease terms. The above‑market and below‑market tenant and ground leases are included in Prepaid expenses and other assets and Accounts payable and accrued expenses, respectively, as detailed in Note 11 – Other Assets and Other Liabilities and are amortized over the remaining non‑cancelable terms of the respective leases.

Amortization/accretion of these intangible assets and liabilities decreased our pre-tax income (excluding the impact of noncontrolling interest and the provision for income taxes) by $6.1 million in 2016, $10.3 million in 2015 and $1.8 million in 2014.

Future amortization/accretion is estimated to decrease pre-tax income (excluding the impact of noncontrolling interest and the provision for income taxes) by $4.9 million in 2017, $4.5 million in 2018, $3.2 million in 2019, $1.6 million in 2020, and $16.9 million thereafter.
