According to Macquarie Equities, Myer is at risk of breaching covenants if earnings before interest, tax, depreciation and amortisation fall by one-third, or if Myer cuts the value of intangibles on its balance sheet by two-thirds. Under existing covenants, Myer must maintain shareholder equity of at least $500 million. Equity at last balance date was $1.07 billion, underpinned by $986 million of intangible assets. If Myer wrote down intangibles including goodwill (which is in the books at $465 million) and brand names ($422 million) by $600 million it would breach the $500 million shareholder equity covenant
