As of September 30, 2026, the website&#x2019;s net book value was $2,350, reflecting accumulated amortization of $650.

This results in a monthly amortization expense of $50, recognized in the Statement of Operations. Beginning October 1, 2026, the Company amortizes the software&#x2019;s cost of $70,380 over five years, resulting in a monthly amortization expense of $1,173. The Company periodically reassesses the estimated useful lives and amortization methods to ensure they remain appropriate and accurately reflect the assets&#x2019; expected consumption of economic benefits.&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;Property and Equipment&lt;/strong&gt;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives.
