Formula and method

Cash of 10,000, marketable securities of 5,000 and receivables of 3,250 total 18,250. Annual operating expenses of 40,150 less 3,650 non-cash charges give daily cash spending of 100, so coverage is 182.5 days.

Daily cash spending = (annual operating expenses − non-cash charges) ÷ 365; coverage days = selected liquid assets ÷ daily cash spending
