a. Increased the interest rate used to discount its pension obligations from \(6.0 \%\) to \(6.5 \%\).

b. Renewed a lease on a roof that the company has been using for a microwave transmission tower. The original lease had four years yet to run; the renewal is for an additional five years. The company is obligated to remove the tower and completely restore the roof when the lease expires.

c. Decided that it is more likely than not that the future benefits of tax loss carryforwards of \(\$ 3.0\) million will be realized. The company's tax rate is \(30 \%\).

d. Realized that a \(\$ 10.0\) million improvement in an automated production line had been charged as an expense in \(20 \times 3\), rather than being recorded as a betterment of a capital asset.
