Impact of new accounting guidance |  | Adoption of new accounting standardsAt the beginning of fiscal 2021, we adopted the guidance in ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The guidance provides for a new impairment model on financial instruments which is based on expected credit losses, which was applied following a modified retrospective approach. Additionally, the new guidance makes targeted improvements to the impairment model for certain available-for-sale debt securities, including eliminating the concept of "other than temporary" from that model. The portion of the guidance related to available-for-sale debt securities was adopted following a prospective approach. The adoption of this ASU did not have a significant impact on earnings or financial condition. Refer to additional disclosures in Notes 2 and 4.
Subsequent Events | Subsequent events We have evaluated subsequent events for potential recognition and disclosure through the date of this filing. Subsequent to the end of the quarter, in September 2020, we sold our McCook, IL building within our LSO segment for $25.1 million. The carrying value of the building was $4.3 million, and we recognized a gain on this sale of approximately $14.8 million, net of taxes and associated transaction costs. We also entered into a separate lease agreement for this facility, which was determined to be an operating lease, and we will have approximately $8.2 million of additional future lease commitments upon commencement of this lease in September 2020. Additionally, in September 2020, we announced the retirement of our Chief Executive Officer, effective February 27, 2021, the end of our current fiscal year, and entered into a transition agreement with him. |
