NOTE 3 – PROPERTY AND EQUIPMENT, NET

 

Property and equipment are stated at cost and depreciated or amortized using the straight-line method based on useful lives as follows (in thousands):

 

   Useful lives (years)  June 30,
2022		   December 31,
2021		 
            
Laboratory equipment  5  $8,619   $9,081 
Furniture, software and office equipment  3 to 5   1,909    1,896 
Leasehold improvements  Shorter of remaining lease term or useful life   8,603    8,603 
Construction-in-progress      —    3,219 
Subtotal      19,131    22,799 
Less: accumulated depreciation      (11,671)   (10,460)
Total property and equipment, net     $7,460   $12,339 

 

Depreciation expense was $0.8 million for the three months ended June 30, 2022 and 2021, respectively, and $1.6 million for the six months ended June 30, 2022 and 2021, respectively. During the three and six months ended June 30, 2022, the Company incurred a loss on disposal of equipment of $0.1 million which is reflected in general and administrative expenses in the condensed consolidated statements of operations and comprehensive loss.

 

On March 31, 2022, the Company announced that it was pursuing a strategic partner to take over development activities of ABO-102 and that it was discontinuing development of ABO-101. As a result of this shift in priorities, the Company determined the construction-in-progress that was dedicated to the ABO-101 and ABO-102 programs had no future value, and thus, the Company recorded an impairment charge of $3.3 million for the three months ended March 31, 2022. During the three months ended June 30, 2022, the Company received a $1.5 million refund from a vendor related to the proposed construction-in-progress and recorded a reduction of the impairment charge of $1.5 million. For the six months ended June 30, 2022, the net impairment charge recorded was $1.8 million.
