Subsequent Events [Text Block]	15. SUBSEQUENT EVENT On April 23, 2018, the Company entered into Amendment No. 1 (the “Repricing Amendment”) to the Amended and Restated Credit Agreement. The Repricing Amendment amended the Amended and Restated Credit Agreement to, among other things, (i) decrease the applicable margin for the Term Loan B to 1.75% for LIBOR borrowings and 0.75% for base rate borrowings, (ii) reset the period during which a prepayment premium in respect of the Term Loan B may be required for a Repricing Transaction until six months after the effective date of the Repricing Amendment and (iii) reset the period during which the Term Loan B benefits from certain “most favored nation” pricing protections until 12 months after the effective date of the Repricing Amendment. Other than as set forth above, all other material terms and provisions of the Senior Credit Facilities remain substantially the same. Debt issuance costs incurred for the repricing totaled $2.0 million.
