[1] The net decrease to the deferred tax asset ("DTA") as at December 29, 2013 due to prior period errors is $791, resulting in an adjusted DTA of $695 compared to the previously filed amount of $1,486.
[2] The property, plant and equipment balance is adjusted to $18,044, representing a $175 reduction resulting from an understatement of the amortization expense previously filed in fiscal 2013 and fiscal 2012 of $102 and $73, respectively.
[3] The net decrease of $129 resulted from a reclassification of $476 pertaining to the derivative liability previously included in accrued liabilities. This was offset by the increase of $347 related to the recognition of the seniority premium for employee benefit obligations in Mexico.
[4] Cash used in accounts payable and accrued liabilities increased by $152 and $531 as at December 29, 2013, which was the result of unpaid property, plant and equipment purchases of $144 offset by cash payments made during 2013 from 2012 additions of $675 which was reclassified from cash flow from investing to accounts payable and accrued liabilities. This was offset by the increased accrual of $32 related to the seniority premium adjustment. Cash provided from accounts payable and accrued liabilities decreased by $497 and $66 respectively as at December 30, 2012, which was the result of unpaid property, plant and equipment purchases of $675 which was reclassified from cash flow from investing. This was offset by the increased accrual of $112 related to the seniority premium adjustment.
