On a quarterly basis, we evaluate the future deployment of our idle fleet under current market conditions. For the three months ended March 31, 2022 and 2021, we determined to retire 10 and 12 compressor units, respectively, for a total of approximately 1,400 and 5,600 horsepower, respectively, that were previously used to provide compression services in our business. As a result, we recorded impairments of compression equipment of $0.4 million and $2.6 million for the three months ended March 31, 2022 and 2021, respectively. The primary causes for these impairments were: (i) units were not considered marketable in the foreseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performance characteristics of the unit, such as the inability to meet current quoting criteria without excessive retrofitting costs. These compression units were written down to their respective estimated salvage values, if any. Identifiable Intangible Assets Identifiable intangible assets, net consisted of the following (in thousands):
| Customer Relationships |  | Trade Names |  | Total
Net balance as of December 31, 2021 | $ | 276,848 |  |  | $ | 27,563 |  |  | $ | 304,411 |
Amortization expense | (6,526) |  |  | (818) |  |  | (7,344) |
Net balance as of March 31, 2022 | $ | 270,322 |  |  | $ | 26,745 |  |  | $ | 297,067 |
Accumulated amortization of intangible assets was $253.6 million and $246.3 million as of March 31, 2022 and December 31, 2021, respectively.
