−Removed: The increase in SG&A expenses for the year ended December 31, 2021 was primarily related to full period expenses from Parcus Medical and Arthrosurface, expansion of our commercial capability in the United States and expanded marketing activities and other operational capabilities to support the growing business needs, higher stock based compensation expense, and a non-cash loss on disposal of fixed assets, partially offset by the absence of transaction costs incurred in 2020 related to acquisitions of Parcus Medical and Arthrosurface. Certain activities were curtailed in the year ended December 31, 2020 due to cost optimization in light of the early stages of the COVID-19 pandemic.
−Removed: Goodwill Impairment Charge
−Removed: We assess goodwill for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment.
−Removed: government policy responses to the COVID-19 pandemic and the resulting changes in healthcare guidelines caused a temporary suspension of domestic elective surgical procedures.

+Added: The growth in SG&A expenses also reflects the increase in certain activities that were curtailed in the early stages of the COVID-19 pandemic, such as travel, as well as higher stock-based compensation expense driven by the growth in personnel to support Anika’s strategic transformation, and higher general corporate costs.
Contingent Consideration Fair Value Change
−Removed: In the year ended December 31, 2021, we recorded a $21.1 million net benefit related to the change in fair value of our contingent consideration liabilities incurred associated with the acquisition of Parcus Medical and Arthrosurface in 2020.

The decrease in fair value of the contingent consideration was due primarily to the decrease in the likelihood that certain contingent milestones would be achieved or because certain contingent milestones were not achieved.
−Removed: Also, in July 2021, we made a regulatory milestone payment in connection with the Arthrosurface acquisition in the amount of $10.0 million upon obtaining a regulatory clearance for a reverse shoulder implant system.

−Removed: The net change in the effective tax rate for the year ended December 31, 2021, as compared to the prior year, was primarily due to lower income before tax in 2021, favorable state tax apportionment, a $0.9 million tax benefit on the decrease in the fair value of contingent consideration and the release of a valuation allowance initially recorded in 2020 in the amount of $0.9 million due to increased likelihood regarding the realizability of certain net deferred tax assets in Italy.
+Added: The increase in our effective rate for the year ended December 31, 2022 as compared to the year ended December 31, 2021 is primarily due to the change in fair value of contingent consideration and the release of the valuation allowance related to the net deferred tax assets in Italy during 2021.

+Added: For the year ended December 31, 2022, net loss was $14.9 million, or $1.02 per diluted share, compared to net income of $4.1 million, or $0.28 per diluted share, for the prior year.

We have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value.
When using the qualitative method in 2022, we considered several factors, including the following:
−Removed: the amount by which the fair value of the reporting unit exceeded its carrying value as of the date of the most recent quantitative impairment analysis, which indicated there would need to be substantial negative developments in the markets in which the reporting unit operates in order for there to be potential impairment;
+Added: the amount by which the fair value of the reporting unit exceeded its carrying value as of the date of the most recent quantitative impairment analysis, which indicated there would need to be substantial negative developments in the markets in which the reporting unit operates for there to be potential impairment;
the carrying value of the reporting unit as of the assessment date compared to their previously calculated fair value as of the date of the most recent quantitative impairment analysis;

stock indices that could suggest declines in overall market stability that could impact the valuation of our reporting unit;
−Removed: whether there had been any significant increases to the weighted-average cost of capital rates for the reporting unit, which could materially lower our prior valuation conclusions under a discounted cash flow approach.
+Added: whether there had been any significant increases in the weighted-average cost of capital rates for the reporting unit, which could materially lower our prior valuation conclusions under a discounted cash flow approach.
Significant assumptions utilized in the impairment analysis included valuation multiple with respect to revenue and weighted-average cost of capital.
−Removed: Based on sensitivity analysis performed on key assumptions at November 30, 2021, a 10% decrease valuation multiples or a 10% increase in the weighted average cost of capital assumption would not have resulted in a fair value below the reporting unit’s carrying value.
+Added: Based on sensitivity analysis performed on key assumptions at November 30, 2022, a 10% decrease in valuation multiples or a 10% increase in the weighted average cost of capital assumption would not have resulted in a fair value below the reporting unit’s carrying value.
Accordingly, we determined it was not more likely than not that the fair value of the legacy Anika reporting unit is less than its carrying amount and thus goodwill was not impaired as of November 30, 2022.

+Added: During 2021, we decided not to further invest in certain of our projects and recorded an impairment charge in the amount of $0.6 million in 2021, in research and development expenses in the consolidated statements of operations.
Based on a sensitivity analysis performed on key assumptions at November 30, 2022 with respect to the remaining IPR&D, a 10% decrease in the long-term growth factor assumption, or 10% increase in the weighted average cost of capital assumption would not have resulted in a fair value below the IPR&D carrying value.
