A magazine publisher offers a reduced annual subscription fee if customers pay for three years in advance. Under this subscription program, the magazine publisher receives from customers \(\$ 45,000\), which it credits to the account Advances from Customers. The estimated cost of publishing and distributing magazines for these customers is \(\$ 32,000\). Why does accounting report a liability of \(\$ 45,000\) instead of \(\$ 32,000\) ?
