Six years ago, the first Mariana 10:10 Plan, designed in conjunction with Lowes Financial Management, was released into the retail space. Today, 49 tranches (138 Options) and 41 maturities later, we are able to reflect on what has proven to be a mainstay within the sector.

The first issue of the 10:10 Plan which struck in October 2015 comprised of two options, each deriving their performance from the FTSE 100 Index. In contrast, the most recent issue, Mariana 10:10 Plan December 2021, is comprised of three options each linked to the new FTSE CSDI.

The 10:10 Plan itself has a number of typical features that have remained constant since the pilot launch. Namely, all issues have been autocall contracts meaning that they have been able to mature early on predetermined dates under pre-defined market conditions. The 10:10 Plan has also been consistent in providing a maximum investment term of ten years, which could prove valuable in the event of a prolonged recovery following another black swan event.

Similarly, all issues of the 10:10 Plan have incorporated a 70% European capital protection barrier, meaning that falls in the underlying due to out of the ordinary events such as the Covid correction have no bearing on the barrier, provided the index recovers to at least above the barrier, or better still, the maturity trigger point before the final maturity date.

However, there have been a anumber of different features within the 10:10 Plan remit...

A total of 6 counterparty banks have been behind the 10:10 Plans, with the most common being Société Générale, accounting for 38 Options with the majority of these further diversifying the counterparty risk across four alternative major financial institutions.

10:10 Counterparty Breakdown by Products Issued


The counterparty bank for the December 2021 10:10 Plan is Citigroup Global Markets Ltd.

Another relatively new differential amongst the 10:10 Plans is the index deployed as the underlying. Whilst every issue of the 10:10 have been indirectly linked to the performance of the UK stock market, all but three of the first 111 Options were linked to the performance of the FTSE 100 Index. The three, which were issued in April 2016, were linked to the FTSE 100 Index and Euro Stoxx 50 Index. The most recent 27 Options issued derive their performance from the FTSE Custom 100 Synthetic 3.5% Fixed Dividend (CSDI) Index. Following the pandemic, the cause for, and rationale behind the change in underlying is explained here

Of the 138 options released into the retail space, 41 (including the three dual index plans) have matured so far, producing capital gains for investors. To allow comparison, we have included the maturity performance of all FTSE 100 linked capital-at-risk autocall products in the sector since the first 10:10 maturity in October 2018.

The 10:10 maturities have achieved an annualised return of 8.53% across an average term of almost three years, outperforming the sector average annualised return by 1.16%.These amply inflation busting figures are certainly nothing to be scoffed at, not least because the FTSE 100 hasn’t enjoyed similar performance.

94 options remain in force, with three further options set to strike on 17th December 2021 – a step down, an at-the-money and a hurdle option – each linked to the performance of the FTSE CSDI. None of the plans in issue will mature with a loss unless they fail to mature early and the FTSE 100 closes below 5,331 (or FTSE CDSI below 115) at the end of their ten-year terms, or the counterparty defaults.
