capital losses on Gilts

In the following scenario: I buy gilts for £1500, receive one coupon payment £100, then they depreciate in value and sell all for £1000, how much income and capital losses should I report on my SA? Is my understand correct that £100 income and £500 capital losses should be reported during my self assessment? Thank you in advance for the answer.
