Appendix – Reconciliation of US GAAP to Non-GAAP EPS (1)See Explanation of Usage of Non-GAAP Performance Measures included in this supplementary information for additional details on the reasons why management believes presentation of each non-GAAP performance measure provides useful information to investors. The supplementary information included in this press release for the three and six months ended October 31, 2021 is preliminary and subject to change prior to the filing of our upcoming Quarterly Report on Form 10-Q with the Securities and Exchange Commission. (2)All amounts are approximate due to rounding. (3)Reflects the amortization of intangible assets established on the opening balance sheet for an acquired business. This includes the amortization of intangible assets such as developed technology, customer relationships, tradenames, etc., which is reflected in the "Amortization of intangible assets" line in the Condensed Consolidated Statements of Net Income. It also includes the amortization of acquired product development assets, which is reflected in "Cost of sales" in the Condensed Consolidated Statements of Net Income. (4)The gain on sale of certain assets is due to the sale of our world languages product portfolio which was included in our Academic & Professional Learning segment and resulted in a pretax gain of approximately $3.7 million during the six months ended October 31, 2021. (5)In the three months ended July 31, 2021, the UK enacted legislation that increased its statutory rate from 19% to 25% effective April 1, 2023. This resulted in a $20.7 million, or $0.37 per share non-cash deferred tax expense from the re-measurement of the Company’s applicable UK net deferred tax liabilities during the three months ended July 31, 2021. These adjustments impacted deferred taxes. In the three months ended July 31, 2020, the UK enacted legislation that increased its statutory rate from 17% to 19%. This resulted in a $6.7 million, or $0.12 per share non-cash deferred tax expense from the re-measurement of the Company’s applicable UK net deferred tax liabilities during the three months ended July 31, 2020. These adjustments impacted deferred taxes. (6)In connection with the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) and certain regulations, we carried back our April 30, 2020 US net operating loss (NOL) to our year ended April 30, 2015 and claimed a $20.7 million refund. The refund plus interest was received in February 2021. The NOL was carried back to fiscal year 2015 when the US corporate tax rate was 35.0%. The carryback to a year with a higher rate, plus certain additional net permanent deductions included in the carryback resulted in a $14.0 million tax benefit, or $(0.25) per share, $8.4 million from current taxes and $5.6 million from deferred taxes, for the three and six months ended October 31, 2020. (7)For the three and six months ended October 31, 2021 and 2020, substantially all of the tax impact was from deferred taxes.
