Equity crowdfunding in New Zealand: a progressive experiment
When the first tranche of provisions of the Financial Markets Conduct Act 2013 (‘the FMC Act’) came into force on 1 April 2014, a new licensing regime for crowdfunding service providers (‘CSPs’) was introduced into New Zealand law – one of the most progressive and innovative operating in the world today. The regime works on the basis that an offer of financial products to an investor does not require the FMC Act's standard disclosure documents necessary for an initial public offering, if the offer of financial products is by, or through, a licensed CSP and the offer is under the market service licence held by the CSP.
The paper starts with an overview of the nature of equity crowdfunding and how it implicates securities law. It then briefly outlines how this activity was regulated in New Zealand previously and discusses how the new regulatory framework operates. The final part of the paper describes how the crowdfunding markets have developed in the last two years and identifies future developments and potential threats to the operation of New Zealand’s crowdfunding regime
Institutional Investors and Corporate Governance: A New Zealand Perspective
In recent years there has been an increasing expectation that institutional investors should
become more active in the corporate governance of companies in which they invest. The plethora of
renowned corporate governance failures in the last decade has only added to this expectation. The
first part of this paper examines the central arguments supporting increased institutional
shareholder activism in corporate governance. The paper then explores, in the New Zealand context,
the constraints against increased involvement and argues that the proposition for institutional
investors as active shareholders is more normative than realistic, given both the legal and
economical barriers that actively discourage intervention by institutions in their investments
Lower Rydberg 2D states of the lithium atom: Finite-nuclear-mass calculations with explicitly correlated Gaussian functions
Very accurate variational nonrelativistic calculations are performed for the five lowest Rydberg 2D states
(1s2nd1, n = 3, . . . ,7) of the lithium atom (7Li). The finite-nuclear-mass approach is employed and the wave
functions of the states are expanded in terms of all-electron explicitly correlated Gaussian function. Four thousand
Gaussians are used for each state. The calculated relative energies of the states determined with respect to the
2S 1s22s1 ground state are systematically lower than the experimental values by about 2.5 cm−1. As this
value is about the same as the difference between the experimental relative energy between 7Li+ and 7Li in
their ground-state energy and the corresponding calculated nonrelativistic relative energy, we attribute it to the
relativistic effects not included in the present calculation
Refinement of the experimental energy levels of higher 2D Rydberg states of the lithium atom with very accurate quantum mechanical calculations
Very accurate variational non-relativistic calculations are performed for four higher Rydberg 2D
states (1s2nd1, n = 8, . . . , 11) of the lithium atom (7Li). The wave functions of the states are expanded
in terms of all-electron explicitly correlated Gaussian functions and finite nuclear mass is
used. The exponential parameters of the Gaussians are optimized using the variational method with
the aid of the analytical energy gradient determined with respect to those parameters. The results of
the calculations allow for refining the experimental energy levels determined with respect to the 2S
1s22s1 ground stat
Analytical energy gradient in variational calculations of the two lowest 3P states of the carbon atom with explicitly correlated Gaussian basis functions
Variational calculations of ground and excited bound states on atomic and molecular systems
performed with basis functions that explicitly depend on the interparticle distances can generate
very accurate results provided that the basis function parameters are thoroughly optimized by the
minimization of the energy. In this work we have derived the algorithm for the gradient of the
energy determined with respect to the nonlinear exponential parameters of explicitly correlated
Gaussian functions used in calculating n-electron atomic systems with two p-electrons and n−2
s-electrons. The atomic Hamiltonian we used was obtained by rigorously separating out the kinetic
energy of the center of mass motion from the laboratory-frame Hamiltonian and explicitly depends
on the finite mass of the nucleus. The advantage of having the gradient available in the variational
minimization of the energy is demonstrated in the calculations of the ground and the first excited 3P
state of the carbon atom. For the former the lowest energy upper bound ever obtained is reporte
Prediction of 2D Rydberg energy levels of 6Li and 7Li based on very accurate quantum mechanical calculations performed with explicitly correlated Gaussian functions
Very accurate variational nonrelativistic finite-nuclear-mass calculations employing all-electron explicitly correlated Gaussian basis functions are carried out for six Rydberg 2D states (1s2nd, n= 6, . . . , 11) of the 7Li and 6Li isotopes. The exponential parameters of the Gaussian functions are optimized using the variational method with the aid of the analytical energy gradient determined with respect to these parameters. The experimental results for the lower states (n = 3, . . . , 6) and the calculated results for the higher states (n = 7, . . . , 11) fitted with quantum-defect-like formulas
are used to predict the energies of 2D 1s2nd states for 7Li and 6Li with n up to 3
1D states of the beryllium atom: Quantum mechanical nonrelativistic calculations employing explicitly correlated Gaussian functions
Very accurate finite-nuclear-mass variational nonrelativistic calculations are performed for the lowest five
1D states (1s2 2p2, 1s2 2s1 3d1, 1s2 2s1 4d1, 1s2 2s1 5d1, and 1s2 2s1 6d1) of the beryllium atom (9Be). The
wave functions of the states are expanded in terms of all-electron explicitly correlated Gaussian functions. The
exponential parameters of the Gaussians are optimized using the variational method with the aid of the analytical
energy gradient determined with respect to those parameters. The calculations exemplify the level of accuracy
that is now possible with Gaussians in describing bound states of a four-electron system where some of the
electrons are excited into higher angular state
