The Company leases certain equipment, automobiles, manufacturing and office space under operating leases, which are non-cancelable and expire on various dates through the first quarter of 2027. Rental expense for all operating leases was $2.4 million, $2.6 million and $2.5 million in 2018, 2017 and 2016, respectively. The operating lease amounts include the contractual facility lease obligations at the Company's Singapore; Bordeaux, France; Shanghai, China; and Dongtan, Korea sites.

The Company routinely enters into inventory purchase contracts which require purchase commitments. As a result, if the Company experiences lower than anticipated demand for its products, in many cases it would not be able to avoid the cost of purchasing the associated inventory, which could negatively impact its results of operations and liquidity. The Company had purchase commitments of $84.3 million at March 31, 2018, up significantly from previous years primarily due to increased production levels. Of these commitments, $7.9 million represent long term purchase contracts.
