Heart Truths. Within the post, Ngerng created a chart which mapped the relationships between the Prime Minister of Singapore, Lee Hsien Loong, the Central Provident Fund (CPF), the Monetary Authority of Singapore (MAS), Temasek Holdings and the Government of Singapore Investment Corporation (GIC). Ngerng claimed there was an "uncanny resemblance" between this chart and another chart by news agency Channel News Asia regarding the relationship among City Harvest Church leaders, who were being charged with misappropriating funds. The CPF has been described as "a forced savings scheme" for Singaporeans with "monthly contributions into the fund" to be saved for retirement, or for expenses on "property, healthcare, and their children's education", while the GIC has been described to have "indirectly invested" funds from the CPF. Singapore's Ministry of Finance on its part has put forth its explanation as to why CPF funds are invested in Special Singapore Government Securities, to enable CPF Board to be able to pay its members all their monies when due, and the interest that it commits to pay on CPF accounts. The government securities are invested as part of a combined pool of funds managed by GIC, rather than managed in a separate dedicated fund, as a standalone fund would have to be managed conservatively to avoid the risk of failing to meet obligations to CPF members. On 18 May, Prime Minister (PM) Lee responded through his lawyer Davinder Singh, who stated that the blog post alleged that Lee "is guilty of criminal misappropriation of the monies paid by Singaporeans to the CPF" and that the allegations were "false and baseless". Ngerng said that the article was a call for greater transparency on the CPF, the GIC and Temasek Holdings. and called for PM Lee to rebut the points made in his blog post. Singapore's Ministry of Finance has publicly stated that CPF monies are safe as all CPF monies are invested in securities that are issued and guaranteed by the Singapore Government, which is one of the few remaining triple-A credit-rated governments in the world. Ngerng apologized "unreservedly" on 23 May, admitting that his allegation was "false and completely without foundation". On 29 May 2014, Prime Minister Lee filed a defamation lawsuit against Ngerng. In a 4 August affidavit, Ngerng argued that his blog post had been misunderstood, and that he was merely asking for more transparency and accountability for CPF monies. On 7 November
