Special purpose vehicles (SPVs) are legal entities, usually Scottish Limited Partnerships, that allow employers to transfer assets and rights to generate an income stream for an underfunded pension scheme. This reduces the employer's cash commitment and provides asset-backed security compared to a standard schedule of contributions. Key considerations for SPVs include accounting, tax, and actuarial impacts as well as ensuring the assets, capital triggers, and structure do not conflict with an employer's other obligations or a trustee's fiduciary duties.
