Other revenues increased $1.4 million, or 14.3%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The increase was primarily attributable to higher interest income from higher interest rates and higher investment balances and an increase in international fees.
Program revenuesincreased $2.0 million, or 4.9%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The increase was primarily attributable to new PDRs in Australia and Mexico.
Expenses
Total expenses were $86.4 million for the three months ended February 28, 2019 as compared to $87.3 million for the same period in 2018, a decrease of $0.9 million, or 1.0%. Expense summaries for the three months ended February 28, 2019 and changes from the corresponding periods in 2018 are described below:
Compensation, taxes and benefits increased $4.7 million, or 14.0%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The increase was primarily attributable to increased expenditures for resources needed to drive revenue to our Best Western-branded hotels, support operations and support growing self-funding programs. Additionally, there was a general increase in resources over the prior year.
Advertising and promotion decreased $2.4 million, or 16.4%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. While continuing to promote our brands and drive revenues to Best Western-branded hotels, soft brand hotels and SureStay franchises, the decrease was primarily attributable to lower promotion costs, partially offset by an increase in advertising activity.
Depreciation and amortization increased $0.3 million, or 10.6%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The increase was primarily attributable to assets which were placed in service in 2018. We anticipate increases in depreciation and amortization in future periods as we expect to make continued investments in capital assets and infrastructure to drive revenue to hotels and enhance systems.
General and administrative expenses increased $1.4 million, or 7.7%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The increase was primarily attributable to WorldHotels expenses, higher technology support costs and other corporate expenses.
Program cost of sales decreased $4.8 million, or 26.7%, for the three months ended February 28, 2019, as compared to the corresponding period in 2018. The decrease was primarily attributable to lower BWR redemption costs. During the second quarter of 2018, the Company identified and corrected a consistentone-month lag in its recognition of the redemption of free night vouchers, which resulted in a $2.4 million overstatement of accounts receivable as of November 30, 2017 and a net $0.1 million overstatement of program cost of sales during the six months ended May 31, 2017, based on the rollover impact of prior periods. The Company concluded that the effect of the overstatement was not material to prior period financial statements, nor is the correction material to annual operating results for fiscal 2018 and; therefore, we corrected the overstatement in the financial statements for the second quarter of 2018, which resulted in $2.4 million of program cost of sales being recorded in the second quarter of 2018 that related to prior periods.
Income taxes
Income tax provisionwas $4.0 million for the three months ended February 28, 2019, as compared to $1.5 million, for the corresponding period in 2018. Our effective income tax rate from operations was 28%, for the three months ended February 28, 2019 and 45%, for the corresponding period in 2018. The effective income tax rate from operations for the three months ended February 28, 2019 was higher than the United States federal
