CoreCivic Properties
CoreCivic Properties includes the operating results of the properties we leased to government agencies during each period. Total revenue generated by CoreCivic Properties increased $0.3 million, from $4.4 million during the three months ended June 30, 2024 to $4.7 million during the three months ended June 30, 2025, and decreased $8.1 million, from $17.5 million during the six months ended June 30, 2024 to $9.3 million during the six months ended June 30, 2025. CoreCivic Properties' facility net operating income increased $1.6 million, from $1.0 million during the three months ended June 30, 2024 to $2.5 million during the three months ended June 30, 2025, and decreased $6.1 million, from $10.2 million during the six months ended June 30, 2024 to $4.1 million during the six months ended June 30, 2025. During the three and six months ended June 30, 2025, CoreCivic Properties generated 3.2% of our total segment net operating income compared with 2.6% and 5.9%, respectively, during the three and six months ended June 30, 2024.
As previously described herein, on December 6, 2022, we received notice from the CDCR of its intent to terminate the lease agreement for our 2,560-bed California City Facility by March 31, 2024, due to the state's declining inmate population. The California City Facility was idled effective April 1, 2024. Effective April 1, 2025, we entered into a letter agreement with ICE to begin activation efforts at the California City Facility. Because we are now operating the facility rather than leasing it, the California City Facility transitioned from our Properties segment to our Safety segment during the second quarter of 2025. Rental revenue generated from the CDCR at the California City Facility was $8.6 million during the period the lease was active in 2024. Facility net operating loss was $1.1 million and facility net operating income was $6.2 million during the three and six months ended June 30, 2024, respectively, including carrying expenses we continued to incur following the lease termination. Facility net operating loss was $0.9 million during the first quarter of 2025 at the California City Facility while the facility was still being reported in our Properties segment.
General and administrative expenses
For the three months ended June 30, 2025 and 2024, general and administrative expenses totaled $43.9 million and $33.9 million, respectively, while general and administrative expenses totaled $79.9 million and $70.4 million during the six months ended June 30, 2025 and 2024, respectively. General and administrative expenses consist primarily of corporate management salaries and benefits, professional fees, and other administrative expenses. General and administrative expenses increased during the three and six months ended June 30, 2025 when compared to the same periods in 2024 primarily as a result of an increase in corporate salaries and benefits, which was largely related to higher incentive-based compensation. In addition, general and administrative expenses increased in both periods as a result of $1.5 million of expenses incurred in the second quarter of 2025 related to the acquisition of the Farmville Detention Center.
Depreciation and amortization
For the three months ended June 30, 2025 and 2024, depreciation and amortization expense totaled $31.1 million and $32.1 million, respectively, while depreciation and amortization expense totaled $61.6 million and $63.9 million during the six months ended June 30, 2025 and 2024, respectively. Depreciation and amortization expense decreased in both periods primarily as a result of certain assets, including certain information technology assets, becoming fully depreciated. In addition, we have begun to make more investments in "software as a service", or SaaS, technology, which reduces our need to install, maintain, and update certain software applications, but often results in higher operating expenses.
Interest expense, net and expenses associated with debt repayments and refinancing transactions
Interest expense is reported net of interest income for the three and six months ended June 30, 2025 and 2024. Gross interest expense was $18.4 million and $20.1 million for the three months ended June 30, 2025 and 2024, respectively, and was $36.8 million and $42.1 million for the six months ended June 30, 2025 and 2024, respectively. Gross interest expense was based on outstanding borrowings under our revolving credit facility, or Revolving Credit Facility, our outstanding term loan, or Term Loan, or collectively, our Bank Credit Facility, our outstanding senior unsecured notes, and our outstanding non-recourse mortgage note, as well as the amortization of loan costs and unused facility fees. Gross interest income was $5.9 million and $3.0 million for the three months ended June 30, 2025 and 2024, respectively, and was $9.0 million and $6.4 million, for the six months ended June 30, 2025 and 2024, respectively. Gross interest income is earned on notes receivable, investments, cash and cash equivalents, and restricted cash. Interest income also includes interest income associated with the 20-year finance receivable associated with the Lansing Correctional Facility lease to the Kansas Department of Corrections, which commenced in January 2020, and amounted to $2.0 million and $2.1 million for the three months ended June 30, 2025 and 2024, respectively, and $4.1 million and $4.2 million for the six months ended June 30, 2025 and 2024, respectively. During the three and six months ended June 30, 2025, interest income also included $3.2 million and $3.7 million, respectively, for interest collected from the Internal Revenue Service on our ERCs. Net interest expense during the three and six months ended June 30, 2025 decreased when compared to the same periods in 2024 primarily as a result of a decrease in our average outstanding debt balances combined with a decrease in the interest rates associated with our variable rate debt, as further described hereinafter.
