The following table provides the gross carrying value, accumulated amortization, net book value and remaining useful life for intangible assets subject to amortization as of June 30, 2022:

Accreditations and regulatory approvals - MIAT	$	12,800	$	—	$	12,800	Indefinite
Trademarks and trade names - MIAT	3,000		—		3,000		Indefinite

Non-compete agreement and trade name	442		(345)		97		2.83
Total	$	16,642	$	(398)	$	16,244	3.99

Of the $16.6 million gross carrying value recorded as intangible assets as of June 30, 2022, $16.2 million relates to the MIAT acquisition completed on November 1, 2021 as previously described in Note 4. The remaining weighted average useful lives shown are calculated based on the net book value and remaining amortization period of each respective intangible asset. Amortization is computed using the straight-line method based on estimated useful lives of the related assets. Amortization expense related to finite-lived intangible assets was $79.9 thousand and $26.6 thousand for the nine months ended June 30, 2022 and 2021, respectively.

As discussed in our new significant accounting policy on intangible assets in Note 2, our indefinite-lived intangible assets are reviewed at least annually for impairment as of August 1, or more frequently if there are indicators of impairment. There were no indicators of impairment for our indefinite-lived intangible assets as of June 30, 2022.
