Installment payment agreement
The Company has entered into an installment payment agreement (“IPA”) with a vendor. Under the IPA the Company may purchase network equipment in exchange for interest free note obligations each with a twenty-four month term. There are no payments under each note obligation for the first six months followed by eighteen equal installment payments for the remaining eighteen month term. As of December 31, 2019 and December 31, 2018, there was $12.5 million and $11.2 million, respectively, of note obligations outstanding under the IPA, secured by the related equipment. The Company recorded the assets purchased and the present value of the note obligation utilizing an imputed interest rate. The resulting discounts totaling $0.4 million and $0.4 million as of December 31, 2019 and December 31, 2018, respectively, under the note obligations are being amortized over the note term using the effective interest rate method.
