Kizys Inc. (Kizys), a publicly accountable enterprise, operates in three business areas:
fibre optics, cable TV, and internet services. The fibre optics business has struggled for a number of years, and on March 31, 2020, the board decided to sell the business. A plan was drawn up and the business was put up for sale on June 1, 2020. Management determined the fibre optics business qualified at a non-current asset held for sale on June 1, 2020.
At June 1, 2020, the assets of the disposal group had a carrying value of $15.8 million.
Liabilities to be repaid of as part of the business equalled $1.6 million. The assets of the business had been impaired by $1.5 million in 2018 due to market conditions. There is no goodwill associated with the assets of the group.
At June 1, 2020, the directors estimated that the assets and liabilities of the business had a fair value of $14 million, with costs to sell of $0.2 million. Selling costs are deemed to relate to the assets of the business.
As at December 31, 2020, the company’s year end, the estimated fair value less costs to sell was $17 million — an increase in value due to an improvement of market conditions.
The liabilities of the division equalled $2.1 million on December 31, 2020, and $1.4 million at the date of sale. At all times, the fair value of the liabilities equalled their book value.
The company follows the cost model for all of its non-current assets.
The business was sold in April 2021 for $18.7 million, net of selling costs.
