Business acquisition, description	the Company entered into two interest rate swaps with UBS AG designed to protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows on a portion of the current floating rate debt facilities. The swaps fix the variable interest rate of the current debt facilities and provide protection over potential interest rate increases by providing a fixed rate of interest payment in return. These interest rate swaps are for £95 million ($129.7 million) at a fixed rate of 0.9255% based on the 6-month LIBOR rate and for €60 million ($73.7 million) at a fixed rate of 0.102% based on the 6 month EURIBOR rate and are effective until maturity on October 1, 2023.		the Company was party to a 3-year, fixed-rate, cross-currency swap with Nomura Global Financial Products Inc. which swapped the principal and interest payments that would be payable in USD under the NPA to Euros (“EUR”), in part, and GBP, in part. Specifically, with respect to the principal payments 1/3 of the payments would be swapped from USD to EUR and 2/3 of the payments from USD to GBP. Additionally, with respect to the interest payments 1/3 would be swapped from USD to GBP and 2/3 from USD to EUR. The swap provided for a foreign exchange rate of $1.13935 USD per €1 EUR and $1.27565 USD per £1 GBP. In connection with the entry into the Senior Facilities Agreement on October 1, 2019, the Company terminated the 3-year, fixed-rate, cross-currency swap and received a settlement of $1.5 million
