Other Revenue
Other revenue decreased $0.5 million, or 6%, and $0.6 million, or 3% during the three and nine months ended September 30, 2023, as compared to the corresponding period in 2022. The decreases are primarily due to decreases in advertising, line assurance and other miscellaneous revenue, partially offset by increases in paper statement revenue.
Operating expenses (excluding depreciation and amortization)
Operating expenses (excluding depreciation and amortization) decreased $3.5 million, or 4%, and $20.1 million, or 8%, during the three and nine months ended September 30, 2023, as compared to the corresponding periods in 2022. The decreases are primarily driven by decreases in direct operating expenses, specifically programming expenses of $4.9 million and $16.0 million, respectively, which aligns with the reduction in Video RGUs between periods and increases in capitalized labor, partially offset by increases in bad debt expense and software and hardware costs.
Incremental contribution
Incremental contribution is defined as subscription services revenue less costs directly incurred from third parties in connection with the provision of such services to our customers (service direct expense). Incremental contribution increased $3.8 million, or 3%, during the three months ended September 30, 2023 compared to the three months ended September 30, 2022 and $8.7 million, or 2%, during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.
Selling, general and administrative expenses
Selling, general and administrative expenses decreased $2.2 million, or 6%, and increased $49.3 million, or 42%, during the three and nine months ended September 30, 2023, respectively, compared to the corresponding periods in 2022. For the three months ended, the decrease is primarily attributable to the reduction in stock compensation and marketing expenses, partially offset by increases in restructuring costs related to employee severance and professional service fees. For the nine months ended, the increase is primarily attributable to the patent litigation settlement, increases in restructuring costs associated with employee severance charges and professional service fees, partially offset by a reduction in stock compensation expense and certain cash compensation expenses.
Depreciation and amortization expenses
Depreciation and amortization expenses increased $4.4 million, or 10%, and $8.7 million, or 7%, during the three and nine months ended September 30, 2023, respectively, compared to the corresponding periods in 2022. The increases are primarily due to increases of equipment placed into service as we continue to expand our network.
Impairment losses on intangibles
The Company recognized a non-cash impairment charge related to its franchise operating rights of $131.7 million and $259.8 million for the three and nine months ended September 30, 2023. The impairment charge is primarily due to declining cash flows, which results in an increase in the discount rate, combined with the decline in the Company’s common stock price. If the common stock price continues to decrease or the Company experiences a significant decrease in cash flow, then the Company may incur future non-cash impairment charges on its franchise operating right assets. See Note 5 – Franchising Operating Rights and Goodwill for discussion of non-cash impairment charge.
Interest expense
Interest expense increased $8.4 million, or 80%, and $25.3 million, or 98%, during the three and nine months ended September 30, 2023, respectively, compared to the corresponding periods in 2022. The increases are primarily due to higher interest rates and additional borrowings on the revolving credit facility during the three and nine months ended September 30, 2023.
