|  | 2017 |  | 2016
Numerator: |  |  |  |
Net loss attributable to controlling interests |  | $ | (40,781 | ) |  | $ | (6,335 | )
Denominator: |  |  |  |  |  |
Basic (including unvested share-based payment awards) (1) |  | 13,925 |  |  | 13,867 |
Effect of dilutive stock compensation arrangements (2) |  | 15 |  |  | 70 |
Diluted (including unvested share-based payment awards) (1) |  | 13,940 |  |  | 13,937 |

Net loss attributable to controlling interests per common share—diluted |  | $ | (2.93 | ) |  | $ | (0.46 | )
(1) | Shares related to unvested share-based payment awards included in our basic and diluted share counts were 281,282 for the year ended December 31, 2017, compared to 300,478 for the year ended December 31, 2016.
(2) | The effect of dilutive stock compensation arrangements is shown only for informational purposes where we are in a net loss position. In such situations, the effect of including outstanding options and restricted stock would be anti-dilutive, and they are thus excluded from all loss period calculations.
