Mortgage Overpayment vs. Shares

Tron103

Hi! 

Hoping for some opinions. I work for a large FTSE 100 Company. Part of my Reward package is receiving shares equivalent to 25% of my salary on an annual basis (give or take). These are taxable and have a 3 year vesting period. The share price is relatively stable. My current shares balance is ~100k (net)

We also have a large mortgage (~600k) and although we are youngish this takes a big chunk of our monthly income. It’s affordable but not particularly enjoyable. 

I wanted to get opinion as to what point (if any) there is value in using shares to pay of a chunk of the mortgage. Or if this is never a good idea?

Holding a large quantity of shares in a single company is high risk especially in the company you work for, if company runs in to financial trouble you could see a large loss at the same time as losing your job.

That does not mean you should use them to pay down your mortgage, that depends on the mortgage rate you are paying and the amount of income that. £100k could earn. If the former is higher than the later then it might be worth doing.
