BL Ltd operates in the high$-$technology energy solutions sector. The PV Division designs, manufactures and installs solar panel systems $($also known as PV$,$ photovoltaic panels$).$ These systems are sold as either: small, medium or large systems. Small systems have a peak power generating capacity up to $100$ kW $($kilowatts$,$ where one KW $=1000$ watts$)$; medium systems up to $1$ MW $($megawatts$,$ where $1000$ kilowatts $=1$ megawatt$)$; and large systems above $1$ MW $($megawatt$).$ The following information relates to the planning and actual data for $2023,$ as well as some actual data for $2022.$

Note: sales volume and market data are reflected in terms of power generating capacity $($MWs$)$ rather than number of units.Based on the above information, which of the following statements are correct:

Note: multiple answers possible.

The budgeted market share estimate when the $2023$ budget was prepared was approximately $3\mathrm{.}84\%$ which was above the actual market share

of $2\mathrm{.}92\%$

The budgeted market share estimated when the $2023$ budget was prepared was approximately $4\mathrm{.}04\%,$ which was above the actual market share of $2\mathrm{.}92\%$

The market share variance indicates that the PV division did not meet expectations with respect to market share

The volume variance is negative due to the negative variable cost variance

The favourable product mix variance is due to the actual contribution margin being higher than the planned contribution margin
