NEW YORK >> Apple is opening the doors to its bank vault, saying it will distribute $100 billion in cash to its shareholders by the end of 2015. At the same time, the company said revenue for the current quarter could fall from the year before, which would be the first decline in many years.

Apple Inc. said Tuesday it will expand its share buyback program to $60 billion — the largest buyback authorization in history. It is also raising its dividend by 15 percent from $2.65 to $3.05 per share. The dividend yield will be about 3 percent at current stock prices. The average yield for the top 20 dividend-paying companies in the U.S. is 3.1 percent, according to Standard & Poor’s.

Investors have been clamoring for Apple to give them access to its cash hoard, which ended March at an unprecedented $145 billion. Apple’s tight grip on its cash, along with the lack of ground-breaking new products, has been blamed for the steep decline in its stock price over the winter.

News of the cash bonanza coincided with the company’s release of a poor quarterly outlook for the three-month period that ends in June.

Apple released its fiscal second quarter earnings after the stock market closed Tuesday. The company’s stock initially rose 5 percent to $425 in extended trading, then retreated $2.63, or 0.7 percent, to $403.50. The shares are still down 40 percent from a peak of $705.07 hit on Sept. 21, when the iPhone 5 went on sale.

"The decline in Apple’s stock price over the last couple of quarters has been very frustrating for all of us, but we’ll continue to do what we do best," CEO Tim Cook said on a conference call with analysts after the release of the results. But he reinforced that the company’s job is not to boost its stock price.

"The most important objective for Apple will always be creating innovative products," he added.

Apple’s results beat the consensus estimate of analysts who follow the company, though it posted its first profit decline in ten years.

Net income was $9.5 billion, or $10.09 per share, down 18 percent from $11.6 billion, or $12.30 per share, in the same period a year ago.

Revenue was $43.6 billion, up 11 percent from last year’s $39.2 billion.

Analysts were expecting earnings of $9.97 per share on revenue of $42.3 billion, according to FactSet.

For the quarter that just started, Apple said it expects sales of $33.5 billion to $35.5 billion. In the same quarter last year, sales were $35 billion. Wall Street was expecting sales of $38 billion.

The June quarter is generally a weak one for Apple, since consumers tend to wait for the next iPhone, which the company usually releases in the fall. But a year-over-year decline is a signal that Apple is failing to capitalize on the continued growth of smartphone sales. Sales are tapering off in U.S. and other mature markets, and not many consumers in India and China can afford iPhones.

Apple started paying a dividend last summer and has been buying back a modest number of shares, enough to balance the dilution created by its employee stock option program but not to make a dent in its cash pile. The company says it’s now expanding the buybacks from $10 billion to $60 billion. It’s raising the quarterly dividend starting with the payment due May 16.

The company has faced continued pressure from Wall Street over the use of its cash, which earns less than 1 percent in interest. Investors reason that if the company has no better use for the money, it should be handing it over to shareholders. The company had said it was considering ways to use the money, and this year engaged in a public debate with a hedge fund manager who wanted it to institute a new class of preferred shares.

When a company starts doling out its cash to shareholders, it’s usually a sign that its growth is stalling and it’s finding it hard to identify good ways to invest in its own business. But Apple is still growing fast by the standards of large companies, and its cash pile-up is a reflection of the extraordinary success of the iPhone.

Judging by Apple’s stock price, investors have concluded that Apple will never again launch a revolutionary new product like the iPhone or iPad. The commitment to bigger buybacks may reinforce that impression, said David Tan, a Georgetown University assistant professor of strategy who focuses on technology.

"How are we going to read into what this move says about Apple’s long-term prospects?" Tan said. "Does this mean this is all that Apple has left to offer or is this just something temporary while we wait for the next big thing from the company?"

For now, it seems clear Apple’s well of innovation has temporarily run dry, but that doesn’t mean it won’t be replenished soon, Tan said. "What no investor can see is what is happening between closed doors in research and development," Tan said. "R&D is always very secretive. It always takes a very long time between the inception of an idea and commercializing a product."

Investors have grown increasingly frustrated with Apple. The company has only been releasing updates to its existing line of mobile devices and computers since Cook became CEO 20 months ago instead of blazing new technological trails as it did with the iPod’s 2001 unveiling, the iPhone’s 2007 debut and the iPad’s introduction in 2010, said Lauren Balter, an analyst for Oracle Investment Research. At the same time, Samsung Electronics has been gaining market share with larger smartphone screens and other features while Google Inc. is creating a buzz with its own Nexus tablets. Google is also expanding into "wearable computing" with Internet-connected glasses that are expected to go on sale late this year or early next year.

"The market is tired of the same old thing at Apple," Balter said. "Investors are looking for innovation. The reality is that people are looking at other products now and they are looking at other cool features from competitors."

Apple is rumored to be working on a "smart" watch and a revolutionary TV set, but it hasn’t confirmed that. On Tuesday’s call, Cook sounded slightly more open to making an iPhone with a larger screen, saying merely that Apple would not ship a phone with a larger screen as long as that meant tradeoffs in other measures of screen quality, like brightness.
