million and $134 million, net of related taxes, for the six months ended June 30, 2024 and 2023, respectively, due to the increase in amortization of the excess basis of assets with identifiable useful lives and debt, primarily due to a cumulative change in the applicable tax rate. The change in the share of earnings of affiliate in the three and six months ended June 30, 2024, as compared to the corresponding periods in the prior year, was the result of the corresponding increase in net income at Charter, offset by increased amortization.
The following is a discussion of Charter’s results of operations. In order to provide a better understanding of Charter’s operations, we have included a summarized presentation of Charter’s results from operations.

Charter’s revenue increased $26 million and $52 million for the three and six months ended June 30, 2024, respectively, as compared to the corresponding periods in the prior year, primarily due to growth in residential mobile service, residential Internet, enterprise and other revenue, partly offset by lower residential video revenue.
During the three and six months ended June 30, 2024, operating expenses, excluding stock-based compensation, increased $20 million and decreased $149 million, respectively, as compared to the corresponding periods in the prior year. Operating costs during the three and six months ended June 30, 2024, as compared to the corresponding periods in the prior year, were impacted by lower programming costs as a result of fewer video customers and a higher mix of lower cost video packages within Charter’s video customer base, partly offset by contractual rate adjustments, including renewals and increases in amounts paid for retransmission consent. Lower programming costs were offset by higher mobile service direct costs and mobile device sales due to an increase in mobile lines. In addition, costs to service customers decreased primarily due to lower labor costs and, during the three months ended June 30, 2024, lower bad debt expense.
For the three months ended June 30, 2024, as compared to the corresponding period in the prior year, the increases in operating costs described above slightly exceeded the decrease in programming costs. For the six months ended June 30, 2024, as compared to the corresponding period in the prior year, the decrease in programming costs exceeded the increases in operating costs described above.
Charter’s Adjusted OIBDA increased $6 million and $201 million for the three and six months ended June 30, 2024, respectively, as compared to the corresponding periods in the prior year, for the reasons described above.
Depreciation and amortization expense decreased $2 million and $18 million during the three and six months ended June 30, 2024, respectively, as compared to the corresponding periods in the prior year, primarily due to certain assets becoming fully depreciated, partly offset by an increase in depreciation as a result of more recent capital expenditures.
Other expenses, net increased $30 million and $66 million for the three and six months ended June 30, 2024, respectively, as compared to the corresponding periods in the prior year. The increases in other expenses, net were primarily
