Marconi and Son Ltd are auditors of Skyworld Property Ltd. A journal article in Property Survey journal indicates a 25% fall in value of properties in Ho due to the relocation of office to Accra. The company's office blocks were valued at GH5 million, up from GH 4.5 million by a valuer but the property was valued in the name of the Managing Director, Mr Skyworld. The Managing Director refused a suggestion of second valuation on the ground that such cost was unnecessary. Treating the office blocks as an investment property raised profit by GH1,490,000.
