KP Inc. is negotiating a 10-year lease for three floors of space in a commercial office building. KP can't use the space unless a security system is installed. The cost of the system is $50,000, and it will qualify as seven-year recovery property under MACRS. The building's owner has offered KP a choice. The owner will pay for the installation of the security system and charge $79,000 annual rent. Alternatively, KP can pay for the installation of the security system, and the owner will charge only $72,000 annual rent. Assuming that KP has a 21 percent marginal tax rate, cannot make a Section 179 election to expense the $50,000 cost, and uses a 9 percent discount rate to compute NPV, which alternative should it choose?
