The company declared an interim dividend of 5 pence per share, though its sustainability is questionable given that dividends are not well covered by earnings or free cash flows. CML's financial stability is supported by no debt and sufficient short-term assets to cover liabilities; however, it faces challenges with low return on equity and declining earnings growth over recent years despite having experienced management and board members.
