Leases

All of our facilities are leased under operating leases, which expire at various times through 2027. We recorded fixed operating lease cost of $7.7 million for fiscal 2019. Rental expense under the previous guidance for operating leases was $8.3 million and $8.9 million for fiscal years 2018 and 2017, respectively.

Our leases have remaining lease terms of 1 to 8 years, some of which include options to extend for up to 5 years, and some of which include options to terminate within 1 year. For our operating leases, the weighted-average remaining lease term was 5.7 years and the weighted-average discount rate is 7.0% as of December 28, 2019.

Our adoption of Topic 842 resulted in the non-cash recognition of additional net ROU assets and lease liabilities of approximately $29.9 million and $32.3 million, respectively, as of December 30, 2018. The difference between these amounts resulted from an adjustment to the deferred rent balance existing under the prior guidance. Adoption of this standard did not materially affect our consolidated net earnings.
