Synlait Milk (ASX:SM1, NZE:SML) secured amendments and extensions to its syndicated bank facilities as it prepares for the completion of its North Island asset sale on April 1, according to a Monday filing with the Australian and New Zealand bourses.

The key changes include an extension of the NZ$50 million "limit step-down" under the revolving credit facility A, a waiver of the minimum earnings before interest, taxes, depreciation, and amortization event of review with adjusted thresholds for subsequent periods, suspension of the net senior leverage ratio, and the waiver and amendment of interest cover ratio, per the filing.

The amendments also extend the maturity date of revolving credit facility A2 to coincide with the revised step-down date of revolving credit facility A, the filing added.
