Segments and Nature of the Business [Abstract]
Segments and Nature of the Business	5.    Segments and Nature of the Business Our segments include the VITAS segment and the Roto-Rooter segment. Relative contributions of each segment to service revenues and sales were 59% and 41% in 2021, 64% and 36% in 2020 and 66% and 34% in 2019. The vast majority of our service revenues and sales from continuing operations are generated from business within the United States. Service revenues and sales by business segment are shown in Note 2. The reportable segments have been defined along service lines, which is consistent with the way the businesses are managed. In determining reportable segments, the RRSC and RRC operating units of the Roto-Rooter segment have been aggregated on the basis of possessing similar operating and economic characteristics. The characteristics of these operating segments and the basis for aggregation are reviewed annually. We report corporate administrative expenses and unallocated investing and financing income and expense not directly related to either segment as “Corporate”. Corporate administrative expense includes the stewardship, accounting and reporting, legal, tax and other costs of operating a publicly held corporation. Corporate investing and financing income and expenses include the costs and income associated with corporate debt and investment arrangements. ‎ Segment data are set forth below (in thousands): For the Years Ended December 31, 2021 2020 2019After-tax Segment Earnings/(Loss) VITAS $ 162,431  $ 238,782  $ 155,822 Roto-Rooter 166,333  120,394  103,710 Total 328,764  359,176  259,532 Corporate (60,214) (39,710) (39,609)Net income$ 268,550  $ 319,466  $ 219,923 Interest Income VITAS $ 18,378  $ 20,565  $ 18,515 Roto-Rooter 7,304  6,332  8,285 Total 25,682  26,897  26,800 Corporate - 13  -Intercompany eliminations (25,305) (26,153) (26,287)Total interest income$ 377  $ 757  $ 513 Interest Expense VITAS $ 160  $ 166  $ 169 Roto-Rooter 595  340  345 Total 755  506  514 Corporate 1,113  1,849  4,021 Total interest expense$ 1,868  $ 2,355  $ 4,535 Income Tax Provision VITAS $ 52,426  $ 76,473  $ 48,711 Roto-Rooter 51,420  37,038  30,276 Total 103,846  113,511  78,987 Corporate (22,082) (36,987) (37,301)Total income tax provision$ 81,764  $ 76,524  $ 41,686 Identifiable Assets VITAS $ 693,490  $ 672,246  $ 663,455 Roto-Rooter 513,191  499,101  507,480 Total 1,206,681  1,171,347  1,170,935 Corporate 136,042  263,564  97,382 Total identifiable assets$ 1,342,723  $ 1,434,911  $ 1,268,317 Additions to Long-Lived Assets VITAS $ 28,583  $ 28,865  $ 25,530 Roto-Rooter 30,249  27,682  162,494 Total 58,832  56,547  188,024 Corporate 24  5,246  1,000 Total additions to long-lived assets$ 58,856  $ 61,793  $ 189,024 Depreciation and Amortization VITAS $ 23,185  $ 22,239  $ 20,055 Roto-Rooter 35,785  34,208  24,994 Total 58,970  56,447  45,049 Corporate 81  136  156 Total depreciation and amortization$ 59,051  $ 56,583  $ 45,205
