Revenue
For the three months ended June 30, 2020, our revenue decreased by $83.1 million, or 21.3%, to $307.7 million from $390.8 million for the three months ended June 30, 2019. We experienced revenue declines on all of our segments due to lower transaction volumes as a result of COVID-19. Our ITPS, HS, and LLPS segments constituted 79.0%, 16.0%, and 5.0% of total revenue, respectively, for the three months ended June 30, 2020, compared to 79.3%, 16.2%, and 4.5%, respectively, for the three months ended June 30, 2019. The revenue changes by reporting segment were as follows:
ITPS— For the three months ended June 30, 2020, revenue attributable to our ITPS segment decreased by $66.8 million, or 21.6% compared to the same period in the prior year. The majority of this revenue decline is attributable to exiting contracts and statements of work in late 2019 from certain customers with revenue that we believe was unpredictable, non-recurring and were not a strategic fit to Company’s long-term success or unlikely to achieve the Company’s long-term target margins (“transition revenue”) in addition to lower transaction volumes as a result of COVID-19.
HS— For the three months ended June 30, 2020, revenue attributable to our HS segment decreased by $14.3 million, or 22.5% compared to the same period in the prior year primarily due to impact of COVID-19 on our healthcare customers.
LLPS— For the three months ended June 30, 2020, revenue attributable to our LLPS segment decreased by $2.0 million, or 11.6% compared to the same period in the prior year primarily due to a decline in legal claims administration services.
Cost of Revenue
For the three months ended June 30, 2020, our direct costs decreased by $62.0 million, or 20.4%, compared to the three months ended June 30, 2019. On each of our segments, the decrease was primarily attributable to the corresponding decline in revenues. Costs on ITPS segment decreased by $53.8 million, or 21.5%, HS segment decreased by $7.2 million, or 16.6%, and LLPS segment decreased by $1.1 million,or 10.0%.
Cost of revenue for the three months ended June 30, 2020 was 78.6% compared to the 77.7% for the comparable same period in the prior year. The increase in cost of revenues, as a percentage of revenues by 0.8% was primarily due to the impact of costs related to the transition revenue that we expect to see gradually removed to further improve the gross margin profile of the business over the remainder of the year.
Selling, General and Administrative Expenses
SG&A expenses decreased $4.1 million, or 8.1%, to $47.0 million for the three months ended June 30, 2020, compared to $51.2 million for the three months ended June 30, 2019. The decrease was primarily attributable to lower compensation expenses, including lower stock compensation expense that was offset by higher professional fees.
SG&A expenses increased as a percentage of revenues to 15.3% in 2020 as compared to 13.1% in 2019. The increase, as a percentage of revenues by 2.2%, was primarily due to the decline in revenues brought on by the COVID-19 pandemic and the transition revenue.
Depreciation & Amortization
Total depreciation and amortization expense was $22.8 million and $24.8 million for the three months ended June 30, 2020 and 2019, respectively. The decrease in total depreciation and amortization expense was primarily due to a decrease in amortization expense from intangible assets resulting from business combinations completed in prior periods and a decrease in depreciation expense related to an increase in assets that are fully amortized.
