When the goodwill is raised at its full value and written off at retirement of a partner, the remaining partners share goodwill in the Gaining Ratio.

Explanation:
Goodwill is an intangible asset that represents the value of a firm's reputation, customer relationships, and other factors that contribute to its earning capacity. When a partner retires from a partnership, the partnership may choose to write off the entire value of the goodwill associated with that partner's share.

In such a scenario, the remaining partners will continue to share the goodwill amongst themselves based on their Gaining Ratio. The Gaining Ratio is the ratio in which the remaining partners acquire the outgoing partner's share of the partnership.

Here's a step-by-step explanation of how the remaining partners share the goodwill in the Gaining Ratio:

1. Calculate the Gaining Ratio: The Gaining Ratio is determined by taking into account the new profit sharing ratio of the remaining partners after the retirement of the outgoing partner. This ratio is calculated based on the agreed terms and conditions of the partnership agreement or as per the adjustments made at the time of retirement.

2. Determine the value of the retiring partner's share of goodwill: The value of the retiring partner's share of goodwill is determined by deducting the amount written off from the total goodwill of the partnership. This value represents the amount that needs to be distributed among the remaining partners.

3. Share the goodwill in the Gaining Ratio: The value of the retiring partner's share of goodwill is shared among the remaining partners in the Gaining Ratio. Each partner receives a portion of the goodwill based on their agreed share in the partnership's profits.

By sharing the goodwill in the Gaining Ratio, the remaining partners are able to benefit from the retired partner's share of goodwill and continue to build on the firm's reputation and earning capacity.

In conclusion, when the goodwill is raised at its full value and written off at retirement of a partner, the remaining partners share the goodwill in the Gaining Ratio. This ensures a fair distribution of the retired partner's share of goodwill among the remaining partners based on their new profit sharing arrangement.
