Core price as a percentage of related-business revenue was 4.6% and 5.5% for the three months ended March 31, 2021 and 2020, respectively.

The volume increase in our landfill line of business is primarily attributable to increased solid and special waste volumes.

In mid-March 2020, certain customers in these lines of business began adjusting their service levels as a result of the COVID-19 pandemic.

This decline in service activity peaked in the first half of April 2020 and sequentially improved thereafter, but volumes remained below pre-COVID levels during the three months ended March 31, 2021.

Financial information for the three and six months ended June 30, 2020 reflects the transfer of our environmental solutions operating segment from Group 2 to Corporate entities and other.

Corporate entities and other include legal, tax, treasury, information technology, risk management, human resources, closed landfills, other administrative functions, and environmental solutions.

National Accounts revenue included in Corporate entities and other represents the portion of revenue generated from nationwide and regional contracts in markets outside our operating areas where the associated material handling is subcontracted to local operators.

Consequently, substantially all of this revenue is offset with related subcontract costs, which are recorded in cost of operations.

Significant changes in the revenue and operating margins of our reportable segments comparing the three months ended March 31, 2021 and 2020 are discussed below.

Revenue for the three months ended March 31, 2021 increased 3.5% due to an increase in average yield in all lines of business and an increase in volume in our transfer station line of business as well as an increase in solid and special waste volumes in our landfill line of business.

These increases were partially offset by volume declines in our small- and large-container collection lines of business, a decline in construction and demolition volumes in our landfill line of business, and one less workday for the three months ended March 31, 2021 as compared to the same period in 2020.

Operating income in Group 1 increased from $313.6 million for the three months ended March 31, 2020, or a 25.0% operating income margin, to $351.5 million for the three months ended March 31, 2021, or a 27.1% operating income margin.

The following cost categories impacted operating income margin:

• Cost of operations favorably impacted operating income margin for the three months ended March 31, 2021, primarily due to a decrease in labor and related benefits and maintenance and repairs expenses as a result of decreased service levels attributable to the COVID-19 pandemic, decreased landfill operating costs, and one less workday as compared to the same period in 2020.

• Depreciation unfavorably impacted operating income margin for the three months ended March 31, 2021, primarily due to additional assets acquired with our acquisitions.

Revenue for the three months ended March 31, 2021 increased 1.2%, due to an increase in average yield in all lines of business and volume increases in our transfer station line of business as well as an increase in municipal solid waste volumes in our landfill line of business.

This increase was partially offset by volume declines in our collection lines of business and one less workday for the three months ended March 31, 2021 as compared to the same period in 2020.

Operating income in Group 2 increased from $229.3 million for the three months ended March 31, 2020, or a 19.0% operating income margin, to $261.8 million for the three months ended March 31, 2021, or a 21.4% operating income margin.

The following cost categories impacted operating income margin:

• Cost of operations favorably impacted operating income margin for the three months ended March 31, 2021, primarily due to a decrease in labor and related benefits, transfer and disposal costs, and maintenance and repairs expenses as a result of decreased service levels attributable to the COVID-19 pandemic, decreased landfill operating costs, and one less workday as compared to the same period in 2020.

• Depreciation unfavorably impacted operating income margin during the three months ended March 31, 2021, primarily due to additional assets acquired with our acquisitions.

Operating income in Group 1 increased from $320.4 million for the three months ended June 30, 2020, or a 26.0% operating income margin, to $379.8 million for the three months ended June 30, 2021, or a 27.2% operating income margin.

Operating income in Group 1 increased from $633.9 million for the six months ended June 30, 2020, or a 25.5% operating income margin, to $731.3 million for the six months ended June 30, 2021, or a 27.2% operating income margin.

Operating income margin for the three and six months ended June 30, 2021 was favorably impacted by the increase in revenue attributable to economic recovery coupled with the effective management of certain returning costs.

Revenue for the three and six months ended June 30, 2021 increased 16.7% and 8.7%, respectively, due to an increase in average yield in all lines of business.

Additionally, volume increased in our landfill, transfer station, and small- and large-container collection lines of business, partially offset by volume declines in our residential line of business.

Operating income in Group 2 increased from $226.9 million for the three months ended June 30, 2020, or a 19.7% operating income margin, to $283.6 million for the three months ended June 30, 2021, or a 21.1% operating income margin.

Operating income in Group 2 increased from $456.2 million for the six months ended June 30, 2020, or a 19.3% operating income margin, to $545.4 million for the six months ended June 30, 2021, or an 21.3% operating income margin.

The following also impacted operating income margin:

• Cost of operations favorably impacted operating income margin for the three and six months ended June 30, 2021 as a result of revenue growth from economic recovery.

This benefit was partially offset by an increase in fuel, transfer and disposal, and transportation and subcontract costs.

Corporate Entities and Other

Operating loss in our Corporate entities and other segment increased from $109.8 million for the three months ended March 31, 2020 to $120.9 million for the three months ended March 31, 2021.

The operating loss for the three months ended March 31, 2021 was unfavorably impacted by revenue declines related to our environmental solutions business, an unfavorable amortization adjustment related to the asset retirement obligation at one of our closed landfills, and favorable remediation adjustments recognized during the three months ended March 31, 2020, which did not recur in 2021, partially offset by net favorable actuarial developments recognized during the period.

Operating loss in our Corporate entities and other segment decreased from $151.9 million for the three months ended June 30, 2020 to $145.5 million for the three months ended June 30, 2021.

Operating loss in our Corporate entities and other segment increased from $261.6 million for the six months ended June 30, 2020 to $266.4 million for the six months ended June 30, 2021.
