(1) The effective interest rates include amortization of debt discount, amortization of deferred financing costs and non-utilization fees, where applicable, calculated for the three months ended June 30, 2015 and based on the average principal balance outstanding during the period. The average outstanding principal balance of the Revolving Credit Facilities was not significant during the three months ended June 30, 2015, resulting in an effective interest rate that was not meaningful.
(2) Represents the weighted average stated interest rate based on the outstanding principal balance as of June 30, 2015.
(3) Represents the weighted average time to maturity based on the outstanding principal balance as of June 30, 2015.
(4) Variable-rate notes are predominantly hedged with interest rate swaps (see Note 5).
(5) The Company early adopted ASU 2015-03 requiring deferred financing costs to be presented as a direct deduction from the carrying amount of the related indebtedness. The Company records deferred financing costs for its 2013 Credit Facility and 2015 Credit Facility in deferred costs and other assets, net on its consolidated balance sheets.
