Accrued interest and penalties related to unrecognized tax benefits as of December 26, 2020 were $1.7 million; this balance decreased by $0.3 million compared to June 27, 2020, largely due to the expiration of the relevant statute of limitations. We classify interest and penalties as components of income tax expense. It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the next twelve months and an estimate of the range of possible changes includes an increase in our liability of up to $3.2 million. Any prospective adjustments to our unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to our effective tax rate. Accordingly, our effective tax rate could fluctuate materially from period to period. Our major tax jurisdictions are the United States, Hong Kong SAR, Japan and the United Kingdom.
