Amortization of intangibles from acquisitions. Amortization of intangibles from acquisitions decreased by $0.1 million to $6.4 million from $6.5 million for the six months ended June 30, 2023 and 2022, respectively.
We expect that amortization of intangibles from acquisitions will decrease as such costs continue to amortize.
Loss on disposition of long-lived assets. During the six months ended June 30, 2023, we recorded a loss on the disposition of long-lived assets of $0.3 million within our US Telecom segment.
During the six months ended June 30, 2022, we recorded a loss on the disposition of long-lived assets of $3.4 million. Of this amount, $2.4 million was incurred in our US Telecom segment relating to the disposal of certain assets while $1.0 million was incurred in our International Telecom segment as a result of the modification of agreements for the use of other certain assets.
Interest income. Interest income was a nominal amount for both the six months ended June 30, 2023 and 2022.
Interest expense. We incur interest expense on the 2019 CoBank Credit Facility, the Alaska Credit and Term Facilities, the Viya Debt, the One Communications Debt and the Receivables Credit Facility. During 2023, interest expense also includes interest expense on the Sacred Wind Term Debt and the GTT Credit Facilities (each as defined below). We also incurred interest expense on the One Communications Debt, which matured on December 22, 2022. In addition, interest expense also includes commitment fees, letter of credit fees and the amortization of debt issuance costs.
Interest expense increased to $19.3 million from $7.6 million for the six months ended June 30, 2023 and 2022, respectively, as additional interest expense was incurred as a result an increase in borrowings under our credit facilities, the inclusion of Sacred Wind Term Debt and the GTT Credit Facilities in 2023, as well as an increase in interest rates on all floating-rate borrowings.
Other income (expenses). For the six months ended June 30, 2023, other income (expenses) was $2.4 million of income primarily related to gains from our noncontrolling investments.
For the six months ended June 30, 2022, other income (expenses) was $1.5 million of income primarily related to gains from our noncontrolling investments partially offset by increased expenses associated with certain employee benefit plans and losses on foreign currency transactions.
Income taxes. Our effective tax rate for the six months ended June 30, 2023 and 2022 was 43.0% and 23.8%, respectively.
We recorded an income tax benefit of $5.8 million in relation to a pretax loss of $13.5 million for the six months ended June 30, 2023. The effective tax rate for the six months ended June 30, 2023 was primarily impacted by the following items (i) the mix of income generated among the jurisdictions in which we operate, (ii) net expense related to valuation allowances placed on certain deferred tax assets that are not expected to be realizable based on the weight of positive and negative evidence and (iii) discrete items including a $4.0 million benefit from the reversal of an unrecognized tax position due to a statute of limitations expiration, and a $1.3 million expense for interest on unrecognized tax positions.
We recorded an income tax benefit of $1.0 million in relation to a pretax loss of $4.3 million for the six months ended June 30, 2022. The effective tax rate for the six months ended June 30, 2022 was primarily impacted by the following items (i) the mix of income generated among the jurisdictions in which we operate, (ii) a $2.1 million net expense recognized discretely to record a valuation allowance on certain deferred tax assets that are not expected to be realizable based on the weight of positive and negative evidence and (iii) discrete items including a $3.3 million benefit from the reversal of an unrecognized tax position due to a statute of limitations expiration, and a $0.8 million expense for interest on unrecognized tax positions.
