Reserves & Undistributed Reserves Explained: Codes 3100 & 3101

Not all profit a company makes gets paid out to shareholders as dividends — some is deliberately set aside, either for a specific future purpose or simply left in the business to strengthen its financial position.

The codes, and what each one holds

Code 3100 — Reserves records profit formally earmarked for a specific purpose, such as a reserve set aside to fund future capital investment.

Code 3101 — Undistributed Reserves covers retained profit that hasn't been allocated to any specific reserve and hasn't been distributed as dividends. Both are Capital & Reserves codes and normally carry a credit balance.

A worked example

Say a company's directors decide to set aside £10,000 of this year's profit specifically to fund a planned office refurbishment next year, and leave a further £25,000 of profit simply retained in the business without a specific earmark.

Reserves (code 3100): £10,000 credited for the earmarked refurbishment fund.

Undistributed Reserves (code 3101): £25,000 credited for the remaining retained profit.

Why this matters day to day

Distinguishing earmarked reserves from general undistributed profit gives shareholders and lenders a clearer sense of the company's intentions — money set aside for a named purpose signals it's less likely to be paid out as a dividend any time soon. It's largely a presentational split though: both ultimately form part of the same shareholders' equity shown at the bottom of the balance sheet.
