[1] Recorded land value was excluded in the impairment determination.

[2] The insurance recoverable of $9.5 million (NZ$13.6 million) as of December 31, 2016 was presented as part of "Other non-current assets" as the timing of the insurance claim receipt is not fixed nor reliably determinable at the time of issuance of the 2016 Form 10-K. Subsequently, we reclassified the insurance recoverable of $9.8 million (NZ$14.1 million) as of March 31, 2017 to a current asset category as part of "Prepaid and other current assets" based on latest developments on our insurance claim, where we expect to receive the final settlement in less than a year. Refer to further details in Note 19 - Subsequent Events.

[3] $306,000 (NZ$429,000) represents changes in our initial estimates for demolition costs, which are allowable to be recorded in the period of change. Also, this amount included legal costs incurred during the insurance claim process which are reimbursable under our insurance policy.

[4] In line with our standard translation policy, balance sheet items were translated into U.S. dollars based on the spot exchange rate as of March 31, 2017 and December 31, 2016, while the impact on our statement of income was translated using the average exchange rate for the current quarter.

[5] This represents the advance claims settlement from the Insurer of $5.0 million (NZ$7.1 million).
