How do I complete the sentences below?

Question

This below sentences is part of the letter of appointment:

Your basic daily rate of pay is S$ 18.00 per day. Your salary may be adjusted at the Company’s discretion and your performance on the job.

You are entitled S$1.00 per day of increment per year which is as follows:

1st year = S$ 18.00

2nd year = S$ 21.00

3rd year = S$ 22.00

The annuity will stop due reaching the maximum of S$28.00 per day.

My question does the last sentence 'The annuity will stop due reaching the maximum of S$28.00 per day' implied that every year starting from 1st, second , third, fourth and ........ S$1.00 will be added to your daily rate pay until it reaches to a max of S$28.00 per day or is there any other sentences that I can used?

Thank you for your kind assistance.

Answer 1

The pay terms are unclear and the figures don't add up or make sense.

This won't inspire much employee confidence, especially as pay can be changed at the company's discretion.

I wouldn't work for a company that described their terms in that way.

An annuity is different from an annual salary or payment.

I realise that Singlish is different from English, but I think you should get some legal advice on how to prepare an employment contract or find a local example.
