Dividend yields should match SEC yields long term, so the fund should see positive dividend growth from here on out. As a comparison, the iShares Preferred and Income Securities ETF (PFF) noncumulative preferred stock invests in over 400 securities, with the top ten of these comprising 12% of its value. PFFA seems diversified enough, but definitely less than the average preferred shares index fund.

Basically, noncumulative preferred stock is where dividends do not accumulate in arrears. It means that if at any given year the holders of this stock were not paid dividends, they should not expect payment of the same in the future. Skipping dividend payment may happen when the issuing company is not able to achieve the set financial benchmarks.
Examples of Non-Cumulative Preference Shares
There are some preferreds that are not among us anymore and they are not part of the discussion. When a company is in a serious problem even the bonds fall and no one cares about the dividend being cumulative. When you hold a preferred stock bought at $25 that is currently trading at $4, you have to realize that the cumulative clause did not save you. And if for any reason this company survives and the preferred stock starts trading near par again, the cumulative clause is the last reason for that. Noncumulative refers to a type of preferred stock for which dividends are not accumulated over time. The company is not obliged to pay noncumulative stockholders any unpaid dividends.
In many ways, preferred stock shares similar characteristics to bonds, and because of this are sometimes referred to as hybrid securities. But if a company misses dividend payments on preferred stock, investors lose out on that income (unless they own cumulative preferred stock). Cumulative preferred ranks above noncumulative preferred in terms of investment security, so it trades rich to the market for noncumulative preferred. Trading rich means its dividend rate of return is lower and it may have a higher credit rating assigned to the issue compared with that of the noncumulative preferred of the same issuer. A company issues a cumulative preferred so it can price its dividend lower than the market rate for noncumulative preferred.
Missed Payments and Cumulative Preferred Stock
For example, a company issues cumulative preferred stock with a par value of $10,000 and an annual payment rate of 6%. The economy slows down; the company can only afford to pay half the dividend and owes the cumulative preferred shareholder $300 per share. The next year, the economy is even worse and the company can pay no dividend at all; it then owes the shareholder $900 per share. Non-cumulative preferred stock is a type of preferred stock that does not accumulate unpaid dividends. When considering non-cumulative preferred stock, it’s important to understand how it compares to cumulative preferred stock, a similar investment type that does accumulate unpaid dividends.
It means that cumulative preferred shares are important that the noncumulative preferred shares. It is the reason why they are given priority when it comes to the dividend payment. In the case of cumulative preferred shares, the issuing company has to keep track of and pay out dividends first to preferred shareholders in the event dividends were not paid for previous years. If the company later begins to pay dividends again, shareholders with cumulative preferred shares will receive all prior missed dividend payments before common shareholders can receive theirs.
