what are the capitalization periods? Please explain

PHO-7 (LO3) GROUPWORK (Capitalization of Interest) Laserwords Inc. is a book distributor that had been operating in its original facility since 1987. The increase in certification programs and continuing education requirements in several professions has contributed to an annual growth rate of 15% for Laserwords since 2012. Laserwords' original facility became obsolete by early 2017 because of the increased sales volume and the fact that Laserwords now carries CDs in addition to books. On June 1, 2017, Laserwords contracted with Black Construction to have a new building constructed for $4,000,000 on land owned by Laserwords. The payments made by Laserwords to Black Construction are shown in the schedule below.
