Within this segment, our products are sold into the Semiconductor Equipment, Industrial and Medical, Data Center Computing, and Telecom and Networking markets. On April 25, 2022, we acquired 100% of the issued and outstanding shares of capital stock of SL Power, which is based in Calabasas, California.
Within this segment, our products are sold into the Semiconductor Equipment, Industrial and Medical, Data Center Computing, and Telecom and Networking markets. On June 20, 2024, we acquired Airity Technologies, Inc. (“Airity”). This acquisition added high voltage power conversion technologies and products, broadening our range of targeted applications within the Semiconductor Equipment and Industrial and Medical markets. See Note 2.
After that date, the entire balance of our Term Loan Facility will be subject to a variable interest rate. In addition, should we have future borrowings under our Revolving Facility, those borrowings would be subject to a variable rate. As of December 31, 2023, we had $200.0 million in available funding under the Revolving Facility.
Should we have future borrowings under our Term Loan Facility or Revolving Facility, those borrowings would be subject to a variable rate. Other expense, net was $2.0 million in 2024, as compared to $1.8 million of expense in the prior year. Other expense, net consists primarily of foreign exchange gains and losses and other miscellaneous items.
These declines were partially offset by higher revenues in the Industrial and Medical and Telecom and Networking markets, as improved supply of critical components during 2023 enabled us to fulfill demand and reduce backlog for our products. For more details on the trends in our end markets, see “End Markets Summary and Trends” elsewhere in this Item 7.
For more details on the trends in our end markets, see “End Markets Summary and Trends” elsewhere in this Item 7.
The decline was attributable to lower revenue from our Semiconductor Equipment and Data Center Computing markets, both of which experienced a reduced demand environment starting in the fourth quarter 2022 and continued into 2023.
The decline was attributable to lower revenue from our Industrial and Medical and Telecom and Networking markets due to customer inventory rebalancing, resulting in a lower demand environment. These declines were partially offset by higher revenues in the Semiconductor Equipment market, from the 2023 trough level, and growing AI-related demand in the Data Center Computing market.
